Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts production equipment technology, and in particular to a dot-drawing device. Background Technology
[0002] There are many types of car seat rail trim products. To differentiate between different models, it is necessary to mark the trim products with dots. Currently, this dotting process is done manually on the surface of the car seat rails. To reduce manpower, lower costs, and automate the dotting process, a robot has been added to the dotting production line. The robot picks up the seat rail trim and uses a pen at a fixed position to automatically draw dots. Currently, there is no device that can work with a robot to achieve such automated dotting. Summary of the Invention
[0003] This application aims to solve one of the aforementioned technical problems in the prior art. To this end, embodiments of this application provide a dot-drawing device.
[0004] According to an embodiment of this application, a dot drawing device is provided, including a first module, including a first sliding member capable of sliding along a first direction; A pen-holding component is rotatably mounted on the first sliding member. The pen-holding component is provided with a storage slot for holding a pen. The width of the storage slot can be adaptively adjusted according to the size of the pen. The second module includes a second sliding member that can slide along a second direction. The second sliding member is provided with a pen holder and a trigger. Under the action of the second module, the pen holder or the trigger can move to be collinear with the movement path of the pen holding member. During the movement of the pen-holding component from the first module toward the second module, the orientation of the storage slot is adjusted by the adjusting component.
[0005] The above-mentioned dotting device has at least the following beneficial effects: In use, the pen is inserted into the pen holder, the second sliding member moves the pen holder to a position facing the pen holding member, and then the first sliding member moves toward the second sliding member. During the movement of the first sliding member, the adjusting member drives the pen holding member to rotate and adjust its position, so that the pen holding member adjusts the storage slot to face the pen holder before reaching the pen picking position. After the first sliding member reaches the pen picking position, the pen in the pen holder is inserted into the storage slot. Since the width of the storage slot can be adaptively adjusted according to the size of the pen, it can hold the pen and pull the pen out of the pen holder. Then the first sliding member moves back a distance, and the second sliding member moves the trigger to a position facing the pen holding member. The first sliding member moves the pen to a point where it contacts the trigger to complete the pressing and ink dispensing of the pen. Finally, the first sliding member moves the pen holding member back to the dotting position, so that the robot can grasp the seat rail trim and use the fixed pen to dot the work. The dot-drawing device of this application effectively promotes the automation process of dot-drawing operations. The entire process of clamping the brush and pressing the brush to dispense ink does not require manual operation, thereby enabling automatic brush replacement, avoiding production accidents caused by manual brush replacement, and also enabling brush replacement operations without stopping the machine.

[0022] Due to production line upgrade requirements, the dot-marking production line needs to be upgraded from manual to automated operation by machines. To this end, a robot capable of dot-marking has been introduced. The robot moves the seat rail trim to the designated dot position to mark the corresponding dot. However, the paint used for dot-marking is disposable and needs to be replaced regularly. Currently, replacement is done manually, but because the dot position is close to the robot and within the robot's working range, the machine must be stopped every time the dot is replaced, which is very inconvenient and indirectly affects the production line's cycle time and efficiency. Therefore, it is necessary to develop a device that can automatically replace the dot without stopping the machine.
[0023] Reference Figures 1 to 4 The drawing device provided in this application can solve the above problems. Specifically, the drawing device of this application includes a first module, a pen holding component 300, a second module 400, and an adjustment component.
[0024] In this embodiment, the first sliding member 110 of the first module can slide along the first direction. The first direction is the vertical direction. The pen holding member 300 is rotatably disposed on the first sliding member 110. The pen holding member 300 is provided with a storage groove for holding the pen 500. The width of the storage groove can be adaptively adjusted according to the size of the pen 500 so as to be able to hold a fixed type of pen 500.
[0025] The second module 400 includes a second sliding member 430 that can slide along a second direction. In this embodiment, the second direction is horizontal. The second sliding member 430 is provided with a pen holder 440 and a trigger member 460. Under the action of the second module 400, the pen holder 440 or the trigger member 460 can move to be collinear with the movement path of the pen holding member 300. The pen holder 440 is used to hold the pen 500 to be replaced, and the trigger member 460 is used to press the pen 500 to dispense ink. When it is necessary to replace the pen 500 or take the pen 500, the pen holder 440 moves to face the pen holding member 300. When it is necessary to press the pen 500 to dispense ink, the trigger member 460 moves to face the pen holding member 300.
[0026] The function of the adjusting component is as follows: during the movement of the pen-holding component 300 from the first module toward the second module 400, the orientation of the storage slot is adjusted by the adjusting component to facilitate pen retrieval.
[0027] Specifically, such as Figure 3 and Figure 4As shown, in use, the brush 500 is inserted into the brush holder 440. The second sliding member 430 moves the brush holder 440 to a position directly opposite the brush holding member 300. Then, the first sliding member 110 moves towards the second sliding member 430. During the movement of the first sliding member 110, the adjusting member rotates the brush holding member 300 to adjust its position, so that the brush holding member 300 adjusts the storage slot to be directly opposite the brush holder 440 before reaching the brush-taking position. After the first sliding member 110 reaches the brush-taking position, the brush 500 in the brush holder 440 is inserted into the storage slot. Because the width of the storage slot can be adjusted according to… The size of the brush 500 is adaptively adjustable, thus it can hold the brush 500 and pull it away from the pen holder 440. Then, the first sliding member 110 returns to one end, and the second sliding member 430 drives the trigger member 460 to move to the position facing the pen holding member 300. The first sliding member 110 moves the brush 500 to abut against the trigger member 460 to complete the pressing and ink dispensing of the brush 500. Finally, the first sliding member 110 drives the pen holding member 300 to return to the drawing point position, so that the robot can grasp the seat slide rail trim and use the fixed brush 500 to perform the drawing operation.
[0028] The dot-drawing device of this application effectively promotes the automation process of dot-drawing operations. The entire clamping of the pen 500 and the pressing of the pen 500 to dispense ink do not require manual operation, thereby enabling automatic replacement of the pen 500, avoiding production accidents caused by manual pen replacement, and also enabling pen replacement operations without stopping the machine.
[0029] In addition, when the ink in the pen 500 in the storage slot is used up, the pen 500 can be removed manually and a new pen 500 can be placed on the pen holder 440. The pen 500 can be automatically changed and the ink can be dispensed by pressing through the cooperation of the trigger 460 and the pen holder 440, avoiding the situation where the pen tip of the pen 500 is forgotten when the pen is changed manually.
[0030] Furthermore, when the dot-painting production line stops, the first sliding component 110 and the adjusting component can work together to place the pen 500 with its tip facing downwards, preventing the ink on the pen tip from drying out. During normal dot-painting, after each seat rail trim strip is painted, the pen 500 needs to be rotated and swung by the first sliding component 110 and the adjusting component during the robot's material handling process, allowing the ink on the pen 500 to be splashed onto the pen tip for replenishment. This avoids the situation where the pen 500 dries out when placed upside down.
[0031] In some embodiments, such as Figure 2As shown, the adjustment component includes a guide plate, a connecting rod 350, and a grooved wheel 360. One end of the connecting rod 350 is rotatably mounted on the first sliding member 110, and the pen-holding member 300 can rotate with the connecting rod 350. The grooved wheel 360 is rotatably mounted on the other end of the connecting rod 350. The fixedly mounted guide plate is provided with a guide groove 130, and the grooved wheel 360 is located in the guide groove 130.
[0032] In a specific embodiment, a rotating shaft 310 is provided on the first sliding member 110, the pen holding member 300 is rotatably disposed at one end of the rotating shaft 310, and the connecting rod 350 is rotatably disposed at the other end of the rotating shaft 310, so that the pen holding member 300 can rotate with the connecting rod 350.
[0033] In this embodiment of the application, the dot drawing device also includes a standing plate 100. The first module and the guide plate are both fixed on the standing plate 100. The guide groove 130 on the guide plate drives the grooved wheel 360 to move along a predetermined route, which in turn drives the connecting rod 350 to swing. During the swing of the connecting rod 350, the pen holding component 300 is rotated, thereby realizing the direction adjustment of the pen holding component 300.
[0034] In a specific embodiment, the guide groove 130 includes a first straight section, a curved section, and a second straight section arranged sequentially. The first and second straight sections are arranged in a direction parallel to the first direction. When the groove wheel 360 passes through the curved section, it drives the connecting rod 350 to rotate by a preset angle. The straight section fixes the direction of the pen-holding component 300, that is, the final posture of the pen-holding component 300 is determined by the straight section, and the rotation angle and speed of the pen-holding component 300 are determined by the curved section, ensuring that the pen-holding component 300 can rotate to the desired angle and the required pen-flicking amplitude.
[0035] In some embodiments, such as Figure 5 As shown, the pen-holding component 300 includes a fixing member 320 and an elastic member 330. The fixing member 320 is provided with a groove 321. The elastic member 330 is fixed at the opening of the groove 321 to form a storage groove. The depth of the groove 321 is less than the diameter of the pen 500, the depth of the groove 321 is greater than the radius of the pen 500, and the width of the groove 321 is greater than the diameter of the pen 500. This makes it easier to insert the pen 500 into the groove 321, and also makes it easier to use the elastic member 330 to press and confine the pen 500 in the groove 321. It is also compatible with different types of pens 500.
[0036] Among them, the elastic element 330 is a metal sheet or rubber so as to have a certain elastic deformation and be able to provide a certain clamping force.
[0037] In some other embodiments, the pen-holding component 300 further includes a limiting member 340 disposed at the end of the storage slot. The limiting member 340 limits the position of the pen 500 entering the storage slot, ensuring that the position of the pen tip relative to the position of the pen-holding component 300 remains constant each time the pen is taken out, thus guaranteeing that the position of the pen tip's drawing point remains constant after each replacement of the pen 500.
[0038] In some embodiments, the drawing device further includes an assisting component that provides a rotational torque to the pen-holding component 300. Specifically, when the grooved wheel 360 reaches the curved section, the rotational torque provided by the assisting component makes the rotation of the pen-holding component 300 smoother, avoiding jamming or sluggish movement.
[0039] In this embodiment of the application, the assisting component includes an assisting spring 120. One end of the assisting spring 120 is fixed to the upright plate 100, and the other end of the assisting spring 120 is connected to one end of the pen holding component 300. The assisting spring 120 can realize the storage of potential energy and also provide the required rotational torque.
[0040] In some instances, such as Figure 3 and Figure 4 As shown, the first module includes a first cylinder 200, a first limiting block and a second limiting block. The cylinder rod of the first cylinder 200, which is fixedly mounted on the upright plate 100, is connected to the first sliding member 110. The first limiting block and the second limiting block are used to limit the sliding range of the first sliding member 110. Both the first limiting block and the second limiting block are provided with a buffer.
[0041] Specifically, the first cylinder 200 is fixed on the upright plate 100, and the first sliding member 110 is slidably set on the upright plate 100 through the guide rail slider structure. The pen holding member 300 is accurately restricted in the pen picking position and drawing point position by the first limit block and the second limit block. The impact of the cylinder is effectively reduced by setting a buffer on the limit block.
[0042] In some embodiments, the second module 400 includes a second cylinder 420, a third limiting block and a fourth limiting block. The cylinder rod of the fixedly disposed second cylinder 420 is connected to the second sliding member 430. The third limiting block and the fourth limiting block are used to limit the sliding range of the second sliding member 430. Both the third limiting block and the fourth limiting block are provided with a buffer.
[0043] Specifically, the second module 400 also includes a mounting plate 410, which is vertically mounted on the upright plate 100. The second cylinder 420 is fixed to the mounting plate 410, and the second sliding member 430 is slidably mounted on the mounting plate 410 through a guide rail slider structure. The positions of the pen holder 440 and the trigger are accurately limited by the third limit block and the fourth limit block, and the impact of the cylinder is effectively reduced by setting a buffer on the limit block.
[0044] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
