[0020] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0021] This invention provides an automatic dyeing method and apparatus based on a multi-station turntable. The automatic dyeing method includes: after a control module receives a start signal, resetting the second and first cylinders to position the mounting platform above the dye tank; controlling the second cylinder to sequentially move the mounting platform downwards and upwards based on a staining height value to complete the staining operation, wherein the staining height value indicates the distance between the dyeing ball and the liquid surface in the dye tank; and driving the mounting platform laterally towards the turntable based on a reference lateral value and the first cylinder, wherein the reference lateral value is used to indicate the distance between the dyeing ball and the liquid surface in the dye tank. The distance between the workpiece carrier and the dye box is indicated; the dyeing movement distance is determined based on the sum of the workpiece distance value and a preset dyeing adjustment value, wherein the workpiece distance value is used to indicate the height distance between the dyeing soft ball and the upper surface of the target workpiece; the second cylinder is controlled to drive the mounting platform to move down and up to complete the dyeing operation based on the dyeing movement distance; based on the reference lateral value and the first cylinder driving the mounting platform to move laterally in the direction of rotating the dye box, the turntable is controlled to perform one rotation so that the carrier is aligned with the next dyeing soft ball; the next dyeing operation, dyeing operation, and turntable rotation are performed. According to the technical solution of the present invention, multiple dyeing soft balls can be synchronously dipped and dyed by cylinder drive, the elasticity of the dyeing soft balls can be used to achieve printing, and the target workpiece can be moved one station at a time by the turntable control, so that the target workpiece moves one station each time it is dyed, realizing multi-process automatic dyeing, improving dyeing efficiency and automation.

[0022] Reference Figures 1 to 5 First, the structure of the automatic dyeing equipment involved in this embodiment will be described by way of example. The automatic dyeing equipment in this embodiment includes: a turntable 10, a dye table 20, and a control module 30.

[0023] It should be noted that, referring to Figures 1 to 3 Multiple workpiece platforms 11 are arranged side by side on the turntable 10. The workpiece platforms 11 are used to mount the target workpiece 12, such as... Figure 1 As shown, the target workpiece 12 of the carrier table 11 in the straight area near the dye table 20 is dyed by the dyeing soft ball 212. The straight area away from the dye table is used for loading and unloading. The operator can take off the target workpiece 12 that has been dyed in this area and load the target workpiece 12 to be dyed. Of course, loading and unloading can also be carried out by automated devices such as robotic arms. This embodiment does not limit the loading and unloading method of the carrier table 11.

[0024] It should be noted that, referring to Figure 3 and Figure 5Each time the turntable 10 rotates, the workpiece stage 11 moves one station, aligning the target workpiece 12 with the next dyeing soft ball 212. This allows for multiple dyeing operations on different parts of the same target workpiece 12 using multiple dyeing soft balls 212, thus achieving automated multi-position dyeing of the target workpiece 12. Since the position of the soft ball mounting plate 211 is fixed, those skilled in the art are familiar with setting the rotation parameters of the turntable 10 when the moving distance is fixed, and will not be elaborated upon here.

[0025] It should be noted that, referring to Figure 4 The dyeing station 20 is equipped with a first cylinder 41, which is fixedly connected to a cylinder mounting plate 44 in the horizontal direction via a first push rod 43. To improve stability, a fixing rod 45 can be added above the cylinder mounting plate 44, through which the cylinder mounting rod passes. The fixing rod 45 provides support for the upper part of the cylinder mounting plate 44, ensuring the stability of the upper part of the cylinder mounting plate 44 after the second cylinder 42 is installed. The second cylinder 42 is fixedly connected to the mounting platform 22 in the vertical direction via a second push rod 46. The first cylinder 41 drives the first push rod 43 to move back and forth in the horizontal direction, thereby driving the cylinder mounting plate 44 to move in the horizontal direction, which in turn drives the second cylinder 42 and the mounting platform 22 to move in the horizontal direction. The second cylinder 42 drives the mounting platform 22 to move back and forth in the vertical direction. Through the connection structure of the first cylinder 41 and the second cylinder 42, the four-way movement of the mounting platform 22 is realized, providing a moving structural basis for automatic dyeing and printing. The control module 30 is electrically connected to the first cylinder 41 and the second cylinder 42, and can control the first cylinder 41 and the second cylinder 42 through the control module 30, thereby achieving precise control of the dipping and dyeing actions.

[0026] It should be noted that, referring to Figure 3 and Figure 5 The dyeing station 20 is also equipped with multiple dye boxes 23, which are aligned with the carrier stage 11. In the actual printing and dyeing process, the dye color of each process can be different. For example, for the head component, it is necessary to first dye the eye area white as the eye base, and then further dye it black as the eyeball. The dye in each dye box 23 in this embodiment can be adjusted according to the actual printing and dyeing process, and no further limitations are made here.

[0027] It should be noted that, referring to Figure 1 and Figure 5Multiple soft ball mounting plates 211 are arranged side by side on the lower side of the mounting platform 22. The multiple soft ball mounting plates 211 are located between the dye box 23 and the carrier stage 11, and the soft ball mounting plates 211 are respectively aligned with the dye box 23 and the carrier stage 11. At least one soft ball mounting plate 211 has a printing soft ball 212 mounted on its bottom side. Each soft ball mounting plate 211, printing soft ball 212, dye box 23, carrier stage and target workpiece 12 form a workstation. Each time the mounting platform 22 moves, it can drive all the soft ball mounting plates 211 to move synchronously. First, the printing soft ball 212 is dipped in dye in the dye box 23, and then the dipped dye is printed onto the target workpiece 12 at the corresponding position. It is worth noting that the soft ball mounting plate 211 may not be equipped with the dyeing soft ball 212. In the technical solution of this embodiment, each soft ball mounting plate 211 moves synchronously, so the frequency of the dyeing action is fixed. The target workpiece 12 will contact the dyeing soft ball 212 once at a fixed time interval to achieve dyeing. However, for some target workpieces 12 with specific dyeing processes, such as those that require a long time to solidify after being colored with a dye, if they come into contact with the dyeing soft ball 212, the dye may be pushed away, affecting the production quality. In this case, the dyeing soft ball 212 may not be installed on the next soft ball mounting plate 211, so that the target workpiece 12 will not come into contact with the dyeing soft ball 212 at the next station. Process control is achieved by controlling the installation position and whether or not the dyeing soft ball 212 is installed.

[0028] It should be noted that, referring to Figure 5 The bottom of the printing soft ball 212 is the printing area. The shape and height of the printing area of ​​different printing soft balls 212 are different. The maximum thickness of all printing soft balls 212 is the same. Since the printing soft balls 212 in this embodiment are mounted on the soft ball mounting plate 211, and the soft ball mounting plate 211 is mounted on the mounting platform 22, the mounting platform 22 is driven to move by the first cylinder 41 and the second cylinder 42. Therefore, the displacement of each printing soft ball 212 occurs synchronously. Based on this, this embodiment uses printing soft balls 212 with the same maximum thickness, which can ensure that the reachable area of ​​all printing soft balls 212 is the same during synchronous movement. Thus, the synchronous movement of multiple printing soft balls 212 is achieved by driving the mounting platform 22.

[0029] It should be noted that a pressure sensor is provided in the printing and dyeing soft ball 212. The pressure sensor is connected to the control module 30. The pressure sensor is used to detect the pressure value of the printing and dyeing area, so that the control module 30 can collect the pressure in each printing and dyeing operation for subsequent judgment operations.

[0030] It should be noted that, as Figure 1 As shown, the control module 30 can be controlled by the touch screen 31, such as inputting process parameters and importing process documents. This embodiment does not limit the specific touch operation.

[0031] The following is based on Figures 1 to 5 The automatic printing and dyeing equipment shown further illustrates the technical solution of the embodiments of the present invention.

[0032] Reference Figure 6 , Figure 6 The flowchart illustrates an automatic dyeing method based on a multi-station turntable 10, as provided in this embodiment of the invention. This automatic dyeing method based on the multi-station turntable 10 includes, but is not limited to, the following steps: S10, after the control module receives the start signal, it resets the second cylinder and the first cylinder so that the mounting platform is positioned above the dye box; S20, based on the staining height value, the second cylinder drives the mounting platform to move down and up in sequence to complete the staining operation. The staining height value is used to indicate the distance between the printing and dyeing soft ball and the liquid surface of the dye box. S30, the mounting stage is moved laterally toward the turntable based on a reference lateral value and the first cylinder, wherein the reference lateral value is used to indicate the distance between the carrier stage and the dye box; S40, the dyeing movement distance is determined based on the sum of the workpiece distance value and the preset dyeing adjustment value, wherein the workpiece distance value is used to indicate the height distance between the dyeing soft ball and the upper surface of the target workpiece. S50, based on the dyeing movement distance control, the second cylinder drives the mounting platform to move down and up to complete the dyeing operation; S60, based on the reference lateral value and the first cylinder driving the mounting table to move laterally toward the dye box, controls the turntable to perform one rotation so that the carrier stage is aligned with the next printing and dyeing soft ball; S70 executes the next dyeing operation, printing operation, and turntable rotation.

[0033] It should be noted that the reset of the first cylinder 41 and the second cylinder 42 can be achieved by preset coordinates. Since the height of the carrier stage 11 can be lower than the opening of the dye box 23, the second cylinder 42 can be controlled to move upward to the preset reset height value first, and then the first cylinder 41 can be used to achieve lateral movement to avoid interference between the printing and dyeing soft ball 212 and the dye stage 20 during the reset process, and to ensure that the mounting stage 22 and the printing and dyeing soft ball 212 are both located above the dye box 23 after reset.

[0034] It should be noted that the dye tank 23 can be considered to be full of dye in the initial state. Given the known reset position, the distance between the dye ball and the surface of the dye tank 23 in the reset state can be determined, i.e., the staining height value in this embodiment. Using the staining height value as the moving distance, the second cylinder 42 is controlled to move downwards, causing the dyeing ball 212 to come into contact with the dye, thereby achieving dyeing of the dyeing ball 212. After staining is completed, it moves upwards based on the staining height value, causing the dyed dyeing ball 212 to return to the reset position.

[0035] It should be noted that in this embodiment, the target workpiece 12 is sequentially dyed by each dyeing soft ball 212 through the movement of the turntable 10. Therefore, different dyeing soft balls 212 correspond to different processes, and the dyeing position in each process may be different. Thus, the dyeing area of ​​each dyeing soft ball 212 in this embodiment can be different. When the thickness of the dyeing soft balls 212 is the same, the dyeing area can be distinguished by setting different shapes and protrusions of the dyeing soft balls 212. For example, the bottom surface of the dyeing soft ball 212 is not a regular sphere. One dyeing soft ball 212 has a protrusion at the position corresponding to the eyeball area, and another dyeing soft ball 212 has a protrusion at the position corresponding to the nose area. When the displacement is the same, due to the different positions of the protrusions, they contact the target workpiece 12 in the eyeball area and the nose area respectively, thereby achieving different dyeing processes through the same displacement.

[0036] It should be noted that, referring to Figure 1 and Figure 2 Since both the turntable 10 and the dyeing table are fixed installations, the distance between the workpiece platform 11 and the dye box 23 in the working area of ​​the turntable 10 is fixed and measurable. After pre-measurement, the distance is input into the control module 30, and the first cylinder 41 moves with the reference lateral value as the moving distance, so that the mounting platform 22 drives the printing and dyeing soft ball 212 to move from the position of the dye box 23 to the workpiece platform 11, thereby aligning it above the target workpiece 12.

[0037] It should be noted that, referring to Figure 1 and Figure 4 When the dyeing soft ball 212 is aligned above the target workpiece 12, the distance between the dyeing soft ball 212 and the stage is known when the reset height value is known. Based on this, the distance between the dyeing soft ball 212 and the target workpiece 12 can be determined. However, if the moving distance is only the height difference between the two, the dyeing soft ball 212 will only contact the target workpiece 12 after the movement, which cannot ensure the dyeing effect. In this embodiment, the dyeing soft ball 212 is made of soft material, and the dyeing area of ​​the dyeing soft ball 212 is different in different processes. Therefore, the dyeing area of ​​the dyeing soft ball 212 contacts the target workpiece 12 first. Based on this height difference, this embodiment further introduces a dyeing adjustment value to determine the dyeing moving distance, further increasing the moving distance when the mounting stage 22 descends, so that the dyeing area of ​​the dyeing soft ball 212 undergoes elastic deformation, which increases the force during dyeing and also ensures that the dyeing area can completely contact the target workpiece 12, thereby improving the dyeing effect.

[0038] It should be noted that after the dyeing operation is completed, the dye box 23 is returned to the reference horizontal value and dyeing movement distance for dyeing, and the turntable 10 is controlled to move, so that the target workpiece 12 moves to the dyeing soft ball 212 corresponding to the next process, and the cycle is repeated, so that each target workpiece 12 is dyed by all the dyeing soft balls 212 starting from the entrance of the turntable 10, realizing automated dyeing. At the same time, due to the multi-station configuration, the dyeing of multiple target workpieces 12 can be performed simultaneously, for example... Figure 1 As shown, taking 12 printing and dyeing soft balls 212 as an example, a track that can accommodate 12 workpiece platforms 11 can be set on the side of the turntable 10 near the dye table 20, so that each printing and dyeing can be performed on 12 target workpieces 12, and each time it moves one station to realize automatic printing and dyeing.

[0039] Additionally, in one embodiment, during execution Figure 6 Before step S10 shown, there are, but are not limited to, the following steps: S11, Import the target process file of the target workpiece into the control module; S12, the control module determines the reset height value, liquid level reference value, workpiece thickness value, reference lateral value, soft ball thickness value and dyeing adjustment value based on the parsed target process file. Among them, the reset height value is used to indicate the height difference between the mounting platform and the carrier platform after the second cylinder is reset, the liquid level reference value is used to indicate the liquid level height of the dye box, the workpiece thickness value is used to indicate the maximum thickness of the target workpiece, and the soft ball thickness value is used to indicate the maximum thickness of the dyeing soft ball. S13, the control module determines the staining height value based on the reset height value, the liquid level reference value, and the soft ball thickness value; the control module determines the workpiece distance value based on the reset height value, the soft ball thickness value, and the workpiece thickness value.

[0040] It should be noted that, referring to Figure 1 In related technologies, it is necessary to set and adjust the specific movement parameters of the first cylinder 41 and the second cylinder 42, which requires the debugging personnel to spend a lot of time testing. The dyeing and printing process does not require overly precise control. Therefore, this embodiment directly imports the target process file, which only records parameters that can be easily measured. The control parameters of the first cylinder 41 and the second cylinder 42 are calculated using the known fixed parameters and process parameters, which effectively simplifies the complexity of equipment configuration and improves control accuracy.

[0041] It should be noted that the reset height value is the height difference between the mounting platform 22 and the carrier platform 11 after reset. The second cylinder 42 is controlled to rise to the reset position by the reset height value. Since the positions of the carrier platform 11 and the dye platform 20 are fixed, the height difference between the dye platform 20 and the mounting platform 22 can be determined based on the height difference between the carrier platform and the dye platform 20, combined with the reset height value, thus serving as the basis for printing and dyeing control.

[0042] It should be noted that the position of the dye box 23 is also based on the known position of the dye station 20. With the reset height value determined, the height of the soft ball mounting plate 211 after reset can be considered to be known, and the height difference between the soft ball mounting plate 211 and the dye box 23 after reset can also be determined. On this basis, the dye liquor in the dye box 23 is prepared in advance, and its liquid level is easy to measure. The soft ball mounting plate 211 is equipped with printing and dyeing soft balls 212, which face the dye box 23. Therefore, in this embodiment, the difference in the adhesive height between the printing and dyeing area and the liquid surface of the dye box 23 can be determined based on the liquid level value, the reset height value, and the soft ball thickness value. The second cylinder 42 is then controlled to move down in sequence to complete the adhesive application.

[0043] It should be noted that, similarly to the above, when the reset height value is known, the distance between the printing area and the upper surface of the target workpiece 12 can be determined by combining the soft ball thickness value and the workpiece thickness value, thereby determining the workpiece distance value used for lowering the printing area.

[0044] In another embodiment, Figure 6 The step S50 shown also includes, but is not limited to, the following steps: S51, whenever a printing and dyeing operation is completed, the printing and dyeing pressure value collected by the pressure sensor is recorded by the control module; S52, the control module determines the first pressure reference value based on multiple printing and dyeing pressure values ​​of the same printing and dyeing soft ball; S53, when the difference between the newly acquired printing and dyeing pressure value and the first pressure reference value is greater than the preset alarm threshold, or when the newly acquired printing and dyeing pressure value is zero, an alarm signal is generated and an alarm prompt is issued.

[0045] It should be noted that, referring to Figure 1 and Figure 5 For the same printing and dyeing soft ball 212, the moving distance of each printing and dyeing is the same, and the pressure value formed by the elastic deformation is also the same. Even if there is a certain measurement error, the printing and dyeing pressure value collected each time will be within the error range. The first pressure reference value can be calculated by multiple printing and dyeing pressure values, which can provide a more accurate reference value.

[0046] It should be noted that if the difference between a given dyeing pressure value and the first pressure reference value exceeds a preset alarm threshold, it may be due to the target workpiece 12 not being placed accurately, causing the dyeing area to contact the wrong part. Since the surface of the head assembly has an irregular contour, this can lead to excessive or insufficient pressure. In this embodiment, the difference can be an absolute value; when it exceeds the alarm threshold, an alarm is triggered, prompting the operator to correct the corresponding target workpiece 12. Similarly, if the dyeing pressure is 0, but the first pressure reference value is not 0, then the carrier stage 11, where the target workpiece 12 should be placed, is not, and an alarm is triggered accordingly.

[0047] Additionally, in one embodiment, reference is made to Figure 1 After execution Figure 6 Following step S70, the following steps may also be included, but are not limited to: S71, when the first stop signal is received, the operation of the turntable, the first cylinder and the second cylinder is stopped, wherein the first stop signal is used to indicate immediate stop; S72, when a second stop signal is received and at least one printing and dyeing pressure value is not zero, the dyeing operation, printing and dyeing operation and turntable rotation continue to be performed. When all printing and dyeing pressure values ​​are detected to be zero, the operation of the turntable, the first cylinder and the second cylinder is stopped. The second stop signal is used to indicate that the machine is stopped after printing and dyeing is completed.

[0048] It should be noted that the first stop signal can be triggered when an immediate stop is required. For example, if the target workpiece 12 is found to be misplaced and needs to be corrected, after receiving the first stop signal, the movement of all parts will stop immediately, and the current running status can be recorded. It can be restored after restarting.

[0049] It should be noted that the second stop signal can be initiated after the placement of the target workpiece 12 in the current batch is completed. Based on the description of the above embodiment, the target workpiece 12 needs to pass through each dyeing soft ball 212 during the dyeing process. Therefore, the target process files of different target workpieces 12 are different, and it may be necessary to replace the new dyeing soft ball 212. On this basis, the second stop signal can be initiated when the placement of the target workpiece 12 is about to be completed. When the control module 30 detects that the dyeing pressure value of each workpiece is 0, it can be determined that the last target workpiece 12 has been dyed. The remaining carrier table 11 has no target workpiece 12. At this time, the control stops and waits for the next batch of dyeing, which can effectively improve the automation level of dyeing.

[0050] Additionally, in one embodiment, reference is made to Figure 1 After completing step S71 or step S72, the following steps may also be included, but are not limited to: S53, after the mounting platform has moved down, it moves up after a pause based on the staining duration; S54, based on the number of dyeing cycles, controls the second cylinder to drive the mounting platform to make at least one up-and-down reciprocating motion.

[0051] Based on the same pressure sensor, non-zero printing and dyeing pressure values ​​are determined as effective pressure values; based on all effective pressure values, the second pressure reference value corresponding to the printing and dyeing soft ball 212 is determined; and the second pressure reference value corresponding to each printing and dyeing soft ball 212 is written into the target process file.

[0052] It should be noted that, based on the above embodiments, the dyeing pressure value can be used to determine whether the target workpiece 12 is placed correctly. If the first pressure reference value is calculated after multiple collections of dyeing pressure values ​​each time, it is impossible to effectively judge the previous dyeing. In this embodiment, the correspondence between the target workpiece 12 and the target process file is utilized. After each batch of dyeing is completed, the non-zero dyeing pressure value is determined as the effective pressure value. After excluding erroneous parameters, the average value is determined as the second pressure reference value and saved to the target process file. The second pressure reference value can be directly used as the first pressure reference value when the same target process file is imported again, thereby improving efficiency.

[0053] In addition, in one embodiment, the target process document also records the dyeing duration and the number of dyeing cycles. Figure 6 The step S50 shown also includes, but is not limited to, the following steps: It should be noted that for some scenarios requiring special printing and dyeing processes, this embodiment can also record the dyeing time and number of dyeing times in the target process document. The dyeing time determines the dwell time after each printing and dyeing area is pressed onto the target workpiece 12, and the number of dyeing times determines the number of times each target workpiece 12 is printed and dyed in the same process. For example, the target workpiece 12 stays for 2 seconds after each printing and dyeing soft ball 212 is pressed, and the turntable 10 is rotated after 2 printing and dyeing processes, which effectively improves the applicability of the automatic printing and dyeing equipment.

[0054] In another embodiment, after execution Figure 6 Following step S70, the following steps may also be included, but are not limited to: S81, whenever the number of times the coloring operation is performed reaches a preset threshold, the liquid level reference value is reduced based on the preset liquid level drop value; S82, perform the staining operation based on the reduced liquid level reference value.

[0055] It should be noted that during the printing and dyeing process, the height of the dye liquid level will decrease continuously with the number of times the dye is applied. Therefore, this embodiment presets a threshold number of times. After the threshold number is reached, the reference value of the liquid level is reduced, so that the control module triggers the update of the dyeing height value. No manual adjustment is required, and the liquid level of the dye is adaptively reduced.
