Abstract

The present invention relates to a pressing and ironing intelligent device and a pressing and ironing method based on a seat cover. A power device drives a mounting seat and drives a hot stamping head mounted thereon to perform intaglio printing on a fabric laid on an intaglio printing female die. A servo telescopic cylinder drives the mounting seat and drives the hot stamping head and a baffle plate arranged thereon to move in the vertical direction. The baffle plate is mounted on the mounting seat through a cylinder and can adjust the vertical position of the baffle plate relative to the hot stamping head through the cylinder. First, the vertical position of the baffle plate is adjusted through the cylinder so that the bottom surface is slightly lower than the bottom surface of the hot stamping head. After the driving mechanism is started, the baffle plate can contact the cloth surface prior to the hot stamping head, which is convenient for adjusting the parallelism with the cloth surface before the hot stamping head contacts the cloth surface, so as to realize horizontal hot stamping on the cloth surface. Further, the intaglio printing female die is arranged on a detection mechanism of a hot stamping platform, which can monitor the hot stamping pressure at each part of the cloth surface in real time during the intaglio printing operation, and stop the machine in time to adjust the parallelism between the hot stamping head and the cloth surface to ensure the uniformity of hot stamping at each part of the cloth surface.

Description

Technical Field

[0001] The present invention relates to the technical field of hot stamping equipment, and particularly to an intelligent hot stamping device and a hot stamping method based on a seat cover. Background Art

[0002] With the development of the automotive industry, the demand for interior personalization is becoming increasingly strong, and among them, the hot stamping of seat covers is becoming more and more popular in the market. More and more seat cover projects require pattern hot stamping on cowhide, artificial leather, etc.

[0003] Traditional hot stamping equipment basically uses air cylinders for stamping. The pressure and level of the air cylinders cannot be quantitatively controlled, and precise regulation cannot be achieved. During the hot stamping operation, the lack of parallelism between the hot stamping head and the cloth surface makes the contact with the cloth surface uneven, resulting in poor hot stamping quality of the cloth surface. Summary of the Invention

[0004] The present invention provides an intelligent hot stamping device and a hot stamping method based on a seat cover, which can effectively solve the problems in the background art.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] An intelligent hot stamping device based on a seat cover, comprising: a frame and a hot stamping female die, a hot stamping head, a driving mechanism and a detection mechanism provided thereon. The detection mechanism is arranged on the hot stamping platform in cooperation with the hot stamping female die. The hot stamping head is located above the hot stamping female die and is driven by the driving mechanism to approach or move away from the hot stamping female die;

[0007] The driving mechanism includes a mounting seat, a slide rail, a power device fixedly arranged and a limit seat. The slide rail is arranged in the vertical direction and is slidably connected with the limit seat. The hot stamping head is arranged on the mounting seat and is connected to the slide rail through the mounting seat. The power device is connected to the mounting seat;

[0008] The detection mechanism includes a support plate and a pressure sensor. The support plate is arranged on the hot stamping platform. The hot stamping female die is arranged on the support plate. The pressure sensor is arranged on the side of the support plate away from the hot stamping female die.

[0009] Further, two slide rails are arranged in parallel and are respectively connected to both ends of the mounting seat. The power device is connected to the middle position of the mounting seat;

[0010] One end of the slide rail is hinged to the mounting seat. The power device is set as a servo telescopic cylinder, and its output shaft is hinged to the mounting seat.

[0011] Further, it further includes a baffle and a cylinder. The cylinder is arranged on the mounting seat and can drive the baffle to approach or move away from the hot stamping female die.

[0012] Further, the baffles are symmetrically arranged on both sides of the hot stamping head. Four cylinders are symmetrically arranged at the four corners close to the hot stamping head, and four pressure sensors are arranged at the four corners of the support plate.

[0013] Further, the baffle is arranged as an L-shaped folding plate, including a horizontal plate portion and a vertical plate portion. The output shaft of the cylinder is vertically arranged and connected to the horizontal plate portion.

[0014] Further, manual clamps are arranged on the hot stamping platform, and two manual clamps are symmetrically arranged on both sides of the hot stamping female die.

[0015] Further, positioning columns are arranged on the manual clamps, positioning grooves are correspondingly arranged on the hot stamping female die for the positioning columns, and the positioning columns are arranged at intervals from the bottom surface of the positioning grooves.

[0016] A hot stamping method for a hot stamping intelligent device based on a seat cover uses the above-mentioned hot stamping intelligent device and includes the following steps:

[0017] After leveling the hot stamping head and the baffle, start the hot stamping intelligent device;

[0018] Drive the hot stamping head through the driving mechanism to perform intaglio printing on the material laid on the hot stamping female die;

[0019] Detect the pressure value applied to the hot stamping female die during the intaglio printing process through the detection mechanism;

[0020] Stop the machine in time according to the real-time feedback of the detection mechanism and level the baffle.

[0021] Further, during the leveling operation before starting the hot stamping intelligent device:

[0022] A leveling seat is arranged on the hot stamping platform, and the structure of the leveling seat is in an inverted U shape;

[0023] First, remove the baffle on the mounting seat, and lower the hot stamping head through the driving mechanism to fit with the plane of the leveling seat;

[0024] After the bottom of the baffle is attached to the plane of the leveling seat, connect it to the output shaft of the cylinder;

[0025] After removing the leveling seat, fix the hot stamping female die on the detection mechanism, and then zero the readings of the pressure sensors.

[0026] Further, it is characterized in that during the intaglio printing process, the pressure value is fed back by a detection mechanism. Specifically, the sum of the readings of four pressure sensors is denoted as Σ. When the die head descends, when the value of Σ falls within the set interval, the descent stops. When the die head stops descending, the readings of the four pressure sensors are recorded as F1, F2, F3, and F4 respectively.

[0027] And a leveling operation is performed when the following situations occur:

The baffle plate is mounted on the mounting seat through a cylinder and can further adjust the vertical position of the baffle plate relative to the hot stamping head through the cylinder; before the power device drives the hot stamping head to perform intaglio printing operation, first adjust the vertical position of the baffle plate through the cylinder so that the bottom surface is slightly lower than the bottom surface of the hot stamping head, which can make the baffle plate contact the cloth surface before the hot stamping head after the driving mechanism is started, facilitating the adjustment of the parallelism between the hot stamping head and the cloth surface before the hot stamping head contacts the cloth surface, and realizing horizontal hot stamping on the cloth surface.

[0033] Further, the intaglio printing die is arranged on the detection mechanism of the hot stamping platform, which can monitor the hot stamping pressure at various parts of the cloth surface during the intaglio printing operation in real time and adjust the parallelism between the hot stamping head and the cloth surface in time to ensure the uniformity of hot stamping at various parts of the cloth surface.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used herein in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0047] As Figures 1 to 8The shown embodiment is an intelligent pressing device and pressing method based on seat cover, comprising a frame 1 and a hot stamping die 3, a hot stamping head 4, a driving mechanism 5 and a detecting mechanism 6 arranged thereon, wherein the detecting mechanism 6 is arranged on a hot stamping platform 2 in cooperation with the hot stamping die 3, and the hot stamping head 4 is located above the hot stamping die 3 and is driven by the driving mechanism 5 to approach or move away from the hot stamping die 3.

[0048] Among them, the driving mechanism 5 includes a mounting seat 51, a slide rail 52, and a fixed power device 53 and a limit seat 54. The slide rail 52 is arranged in the vertical direction and is slidably connected to the limit seat 54. The hot stamping head 4 is arranged on the mounting seat 51 and is connected to the slide rail 52 through the mounting seat 51. The power device 53 is connected to the mounting seat 51; the detection mechanism 6 includes a support plate 61 and a pressure sensor 62. The support plate 61 is arranged on the hot stamping platform 2, the hot stamping die 3 is arranged on the support plate 61, and the pressure sensor 62 is arranged on the side of the support plate 61 away from the hot stamping die 3.

[0049] like Figures 1 to 3 As shown, in the present application, the mounting seat 51 is driven by the power device 53 and the hot stamping head 4 mounted thereon is driven to perform the gravure printing operation on the fabric laid on the hot stamping concave die 3, wherein the mounting seat 51 is connected to the slide rail 52 and the vertical displacement of the mounting seat 51 is guided by the slide rail 52. The hot stamping concave die 3 is arranged on the detection mechanism 6 of the hot stamping platform 2, which can monitor the hot stamping pressure at various places on the fabric surface in real time during the gravure printing operation, and timely adjust the parallelism between the hot stamping head 4 and the fabric surface to ensure the uniformity of hot stamping at various places on the fabric surface.

[0050] In the present application, two slide rails 52 are arranged in parallel and are respectively connected to the two ends of the mounting seat 51, and the power unit 53 is connected to the middle position of the mounting seat 51; one end of the slide rail 52 is hinged to the mounting seat 51, the power unit 53 is configured as a servo telescopic cylinder, and its output shaft is hinged to the mounting seat 51.

[0051] Servo control is used to replace the traditional downward pressure method of the cylinder 56 to achieve precise speed control and pressure control, making the production process more stable and controllable; the mounting seat 51 is hinged at three connections with the two slide rails 52 and the output shaft of the power device 53, so that the mounting plate can produce slight rotation under the action of external force. In actual production, the thickness of the cloth to be stamped is uneven, and it often gradually thickens from one end of the cloth to the other end; therefore, during the movement of the stamping head 4 toward the stamping die 3, the baffle 55 first contacts the cloth, and when the bottom plate of the baffle 55 is in contact with the cloth, it synchronously drives the adjustment of the stamping head 4 to form a good parallelism between its bottom surface and the cloth.

[0052] Further, such as Figure 3As shown in the figure, it further includes a baffle 55 and a cylinder 56. The cylinder 56 is arranged on the mounting seat 51 and can drive the baffle 55 to approach or move away from the hot stamping female die 3. The baffles 55 are symmetrically arranged on both sides of the hot stamping head 4, and four cylinders 56 are symmetrically arranged at the four corners close to the hot stamping head 4. Four pressure sensors 62 are arranged at the four corners of the support plate 61. The baffle 55 is set as an L-shaped folding plate, including a horizontal plate portion 551 and a vertical plate portion 552. The output shaft of the cylinder 56 is arranged vertically and is connected to the horizontal plate portion 551.

[0053] After the hot stamping head and the bottom of the baffle are leveled, the bottom of the baffle 55 is further slightly lower than the bottom of the hot stamping head 4 under the initial drive of the cylinder, and the constant pressure value of the cylinder is maintained. During the process of the subsequent power device 53 driving the hot stamping head 4 to move towards the hot stamping female die 3, the bottom of the baffle 55 will first contact the cloth surface, which is convenient for adjusting the parallelism between the bottom surface of the hot stamping head 4 and the cloth surface. By providing vertical movement power to different positions of the same baffle 55 through the two cylinders 56 on one side of the hot stamping head 4, and during the continuous downward pressing of the hot stamping head, the four cylinders 56 generate equal tension on the two baffles 55 on both sides. After the bottom of the baffle 55 moves to be parallel to the cloth surface, the hot stamping head 4 will further press towards the hot stamping female die. By providing a constant force through the cylinder 56, the bottom of the baffle 55 will not hinder the downward pressing of the hot stamping head due to the continuous output of the power device after contacting the hot stamping platform 2. Instead, the two baffles on both sides can be slightly deformed outwards, and at the same time, the cloth is flattened, as Figure 8 shown.

[0054] In the present application, as Figure 5 and Figure 6 shown, manual clamps 21 are arranged on the hot stamping platform 2, and two manual clamps 21 are symmetrically arranged on both sides of the hot stamping female die 3. Positioning posts 211 are arranged on the manual clamps 21, and positioning grooves 31 are correspondingly arranged on the hot stamping female die 3 for the positioning posts 211. The bottom surfaces of the positioning posts 211 and the positioning grooves 31 are spaced apart.

[0055] Position the ink grooves on the hot stamping female die 3 and the position of the hot stamping head 4 through the manual clamps 21 symmetrically arranged on both sides of the hot stamping concave plate; when the manual clamps 21 limit and fix the hot stamping concave plate, the end surfaces of the positioning posts 211 arranged on the manual clamps 21 do not fit with the bottom surfaces of the positioning grooves 31, so as to avoid the manual clamps 21 pressing the hot stamping female die 3 and further affecting the reading of the pressure sensor 62 at the bottom of the support plate 61.

[0056] The present invention further discloses a hot stamping method for a hot stamping intelligent device based on a seat cover. Using the above-mentioned hot stamping intelligent device, it includes the following steps:

[0057] After leveling the hot stamping head 4 and the baffle 55, start the hot stamping intelligent device; drive the hot stamping head 4 through the driving mechanism 5 to perform intaglio printing on the material laid on the intaglio die 3; detect the pressure value applied to the intaglio die 3 during the intaglio printing process through the detection mechanism 6; level the baffle 55 in a timely manner by shutting down according to the real-time feedback of the detection mechanism 6.

[0058] In the specific implementation process, drive the mounting seat 51 through the servo telescopic cylinder and drive the hot stamping head 4 and the baffle 55 arranged thereon to move in the vertical direction. The baffle 55 is installed on the mounting seat 51 through the cylinder 56 and can further adjust the vertical position of the baffle 55 relative to the hot stamping head 4 through the cylinder 56; before the power device 53 drives the hot stamping head 4 to perform intaglio printing, first adjust the vertical position of the baffle 55 through the cylinder 56 so that the bottom surface is slightly lower than the bottom surface of the hot stamping head 4, which can make the baffle 55 contact the cloth surface before the hot stamping head 4 after the driving mechanism 5 is started, facilitating the adjustment of the parallelism between the hot stamping head 4 and the cloth surface before contacting the cloth surface, and realizing horizontal hot stamping of the cloth surface.

[0059] Further, as Figure 7 shown, during the leveling operation before starting the hot stamping intelligent device:

[0060] Set a leveling seat 7 on the hot stamping platform 2, and the structure of the leveling seat 7 is in an inverted "U" shape; first remove the baffle 55 on the mounting seat 51, and lower the hot stamping head 4 to fit with the plane of the leveling seat 7 through the driving mechanism 5; after the bottom of the baffle 55 is fitted with the plane of the leveling seat 7, connect it to the output shaft of the cylinder 56; after removing the leveling seat 7, fix the intaglio die 3 on the detection mechanism 6, and then zero the readings of the pressure sensors 62. After leveling, the parallelism between the bottom of the baffle 55 and the bottom surface of the hot stamping head 4 is consistent, which is convenient for slightly adjusting the angle of the hot stamping head 4 through the baffle 55 during the stamping process to make it adapt to the cloth thickness and always be parallel to the cloth surface.

[0061] Further, during the intaglio printing process, the pressure value is fed back through the detection mechanism 6. Specifically, the sum of the readings of the four pressure sensors 62 is recorded as Σ. When the die head descends, when the value of Σ falls within the set interval, the descent stops. When the die head stops descending, record the values of the four pressure sensors 62 as F1, F2, F3, and F4 respectively,

[0062] and perform a leveling operation when the following situations occur:

[0063] a. The variance of F1, F2, F3, and F4 is greater than the set threshold A, indicating that there are obvious differences in the forces at the four corners of the support plate 61 at this time, and the parallelism between the hot stamping head 4 and the cloth surface is insufficient and needs to be leveled again;

[0064] b. If the detected values of any one of the pressure sensors 62 are the maximum or minimum among F1, F2, F3, and F4 for n consecutive times, it indicates that the fixed position of one corner of the hot stamping head 4 is too low or too high;

[0065] c. Any one of F1, F2, F3, and F4 exceeds the set threshold B.

[0066] Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
