Description

Technical Field

[0001] The present invention relates to the technical field of leather processing, and particularly refers to a replaceable mode leather laminating device and method. Background Art

[0002] In the field of industrial manufacturing, the processing method of covering leather on the surface of a mold is widely used, and is commonly seen in industries such as automotive interiors, furniture manufacturing, and luggage production. It can endow products with an aesthetic appearance and a comfortable touch.

[0003] The traditional leather covering mold processing process includes multiple key steps. First, glue needs to be evenly applied on the surface of the lower mold. The quality of glue application directly affects the bonding effect between the leather and the lower mold. If the glue is unevenly applied, it may cause local poor bonding of the leather, resulting in problems such as bubbles and wrinkles, reducing the overall quality of the product. Then, in order to make the glue reach the best viscous state, an infrared lamp module is usually used to activate the glue. The specific wavelength light emitted by the infrared lamp can accelerate the chemical reaction of the glue and make it quickly reach a state suitable for bonding. Finally, the upper mold drives the leather to be pressed onto the surface of the lower mold after glue application to complete the bonding of the leather and the mold.

[0004] In the above process, in order to ensure the consistency and efficiency of the glue activation effect and improve the processing quality, the shape design of the lamp module needs to correspond one by one to the shape of the lower mold. The molds used for different products have various shapes, including flat, curved, and irregular shapes. Therefore, for molds of different shapes, different lamp modules need to be matched. For example, in the leather covering processing of automotive seat interiors, the mold shapes of different parts of the seat vary greatly. Special lamp modules need to be designed to match the molds at positions such as the backrest and seat cushion to ensure that the glue can be evenly activated at each part.

[0005] However, the current processing equipment has obvious shortcomings. The lamp module and the leather transmission structure are integrally arranged. When it is necessary to replace different lamp modules to adapt to molds of different shapes, the available operation methods are extremely limited.

[0006] One way is to disassemble the lamp. However, a large amount of heat is generated during the operation of the infrared lamp, and the temperature of the lamp module is relatively high. Before disassembling the lamp, it is necessary to wait for the lamp module to cool down. Otherwise, the high temperature may cause burns to the operator, and may also damage the lamp and related equipment. This cooling waiting process will consume a large amount of time, resulting in a significant reduction in production efficiency. For example, during the continuous production of products with different shapes, every time the mold is changed, it is necessary to wait for the lamp module to cool down, and the waiting time may be as long as ten or even dozens of minutes each time, seriously affecting the overall production capacity of the production line.

[0007] Another way is to use an external handling device to replace the leather material transmission structure connected to the lamp tube module as a whole. Since the leather material transmission structure is usually large in volume and heavy in weight, professional handling equipment is required for overall replacement, and the operation process is complex and cumbersome. Moreover, the scheduling and use of the handling equipment also require additional time and costs. At the same time, frequent overall replacement may also cause certain damage to the leather material transmission structure, affecting its service life and transmission accuracy.

Detailed implementation manners

[0037] The present invention will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments given are not intended to limit the present invention. Embodiment 1

[0038] Refer to Figure 1As shown in the figure, this embodiment provides a leather laminating device with replaceable modes, which can achieve the purpose of flexible die replacement through the cooperation between the composite function table 300 and the laminating mechanism 400, thereby enabling it to be applicable to the wrapping and processing processes between different leathers and modules. It includes: a leather processing mechanism 100, a transmission mechanism 200, a composite function table 300, and a laminating mechanism 400. Among them, the leather processing mechanism 100 is used for transporting and cutting the rolled leather. The composite function table is used to carry and install the cut leather and the lamp module 340. The transmission mechanism 200 is used to drive the composite function table to move. The laminating mechanism 400 is used to complete the leather laminating process by relatively squeezing the upper and lower dies.

[0039] See Figure 1 and Figure 2 As shown in the figure, in this embodiment, the leather processing mechanism 100 is arranged at the feeding end of the transmission mechanism 200. It includes a coil rack 110, a loading component 120, and a cutting component 130. The leather 500 to be laminated is wound around the coil rack 110. The loading component 120 and the cutting component 130 are arranged in sequence along the transmission direction of the leather 500 to be laminated. Among them, the loading component 120 includes a support roller 121 and a pressing roller 122. The pressing roller 122 moves up and down above the support roller 121 to press / release the leather 500 to be laminated. The cutting component 130 includes a cutter 131. Further, one end of the leather can be clamped between the support roller 121 and the pressing roller 122, and the leather is moved to the composite function table 300 through the support roller 121 and the pressing roller 122. At the same time, the cutter 131 in this embodiment can cut out leathers of different lengths along the horizontal direction according to actual usage requirements. The specific structure of the present invention is not limited thereto.

[0040] See Figure 3 and Figure 4 As shown in the figure, the transmission mechanism 200 includes a base frame 210, a sliding frame 220, and a connecting plate 240. A first horizontal module 211 extending horizontally towards the laminating mechanism 400 is provided on the base frame 210. The sliding frame 220 is slidably connected to the first horizontal module 211, and a first lifting module 221 extending along the height direction of the transmission mechanism 200 is provided thereon. The connecting plate 240 is slidably connected to the first lifting module 221. The table body 310 is detachably connected to the connecting plate 240. Based on the above structure, the flexible movement of the connecting plate 240 in the horizontal and / or vertical directions can be realized, thereby driving the composite function table to be adjusted according to actual usage requirements.

[0041] Specifically, see Figures 3 to 7As shown in the figure, the carriage 220 in this embodiment moves linearly on the base frame 210 through a driving motor, and the connecting plate 240 moves up and down along the carriage 220 through a lifting drive assembly 230. Among them, the lifting drive assembly 230 includes a rotary driver 231, a transmission rod 232, a gear 233 and a rack 234. The rotary driver 231 is arranged on the base frame 210. The transmission rod 232 connects the working end of the rotary driver 231 and the gear 233. The rack 234 is arranged on the connecting plate 240 and extends along the height direction of the transmission mechanism 200. The gear 233 meshes with the rack 234 to drive the connecting plate 240 to move up and down. Based on this structural setting, on the one hand, its load-bearing capacity can be improved, and on the other hand, it can also maintain stable position accuracy in applications that require high-precision positioning and stable operation, reduce vibration and deformation, thereby reducing the mutual wear between the connecting plate 240 and the composite function table 300 and extending its service life.

[0042] In this embodiment, the connecting plate 240 and the composite function table are configured to be detachably connected. Therefore, positioning is required during the disassembly and assembly of the two to ensure the accuracy of the connection position. Based on this, a positioning pin 241 is further provided on the connecting plate 240 in this embodiment. The positioning pin 241 protrudes from the top surface of the connecting plate 240. A positioning hole 312 is provided on the composite function table 300. The positioning holes 312 are arranged in one-to-one correspondence with the positioning pins 241, thereby realizing the positioning connection between the connecting plate 240 and the composite function table 300. Further, in order to improve the relative stability between the two, in this embodiment, the composite function table and the connecting plate 240 are further fixed and limited by bolts and other connecting parts.

[0043] See Figure 5 and Figure 6 As shown in the figure, the composite function table 300 in this embodiment includes a table body 310, a plurality of double-sided plug-in columns 320, a leather pulling assembly 330 and a lamp module 340. The table body 310 is detachably connected to the transmission mechanism 200. The leather pulling assembly 330 is connected to the table body 310 to pull the leather material 500 to be laminated. The lamp module 340 is arranged on the bottom surface of the table body 310. A plurality of the double-sided plug-in columns 320 are arranged around the table body 310. Among them, the table body 310 serves as an installation and connection platform for the leather pulling assembly 330 and the lamp module 340. Positioning holes 312 are respectively provided on both sides thereof for detachably connecting with the connecting plate 240.

[0044] Furthermore, the frustum 310 in this embodiment is configured as a rectangular plate structure, with four bidirectional insertion columns 320 connected thereto, and the four bidirectional insertion columns 320 are respectively arranged at the four corners of the frustum 310, thereby forming a stable support structure for the frustum 310. Specifically, the bidirectional insertion columns 320 in this embodiment extend along the thickness direction of the frustum 310, and the extension thickness is greater than the thickness of the frustum 310. The bidirectional insertion column 320 includes a first body 321, a first insertion bump 322, and a first insertion groove 323. The first body 321 is connected to the frustum 310. The first insertion groove 323 is recessed from the top surface of the first body 321, and the first insertion bump 322 protrudes outward from the first body 321 along the extending direction of the first body 321.

[0045] In this embodiment, the leather pulling assembly 330 is used to move and traction the leather after being cut by the leather processing mechanism 100, so as to make its surface flat and avoid generating bubbles or wrinkles during the subsequent laminating process. Specifically, the leather pulling assembly 330 includes a leather support plate 331 and a plurality of leather pulling jaws 332. The leather support plate 331 is detachably connected to the frustum 310 to receive and support the leather 500 to be laminated. Specifically, there are a plurality of adjustment holes 313 on the frustum, and the leather support plate 331 can be connected to different adjustment holes through connecting pieces such as screws. The plurality of leather pulling jaws 332 are arranged on opposite sides of the leather support plate 331 and can move along the transmission direction of the leather 500 to be laminated. Specifically, as shown in Figure 8 As shown, the leather support plate 331 in this embodiment is used to support the leather to avoid collapse in the middle of the leather. The leather support plate 331 and the frustum 310 are configured as a detachable connection structure, so that the support plate can be set at different positions or different numbers can be installed according to actual usage requirements. The leather pulling jaws 332 move through the second horizontal module 311. During actual operation, the leather pulling jaws 332 need to move to one end of the second horizontal module 311 facing the leather processing mechanism 100 to wait for clamping the leather. After clamping the leather, it can drive the leather to move away from the leather processing mechanism 100 synchronously, and at the same time make the leather 500 to be laminated supported on the leather support plate 331, and it is also configured as a detachable connection structure with the frustum 310. Further, in this embodiment, two leather pulling jaws 332 are provided on opposite sides of the leather to traction both sides of the leather at the same time.

[0046] In this embodiment, the lamp tube module 340 is fixedly connected to the bottom surface of the table body 310 and can move synchronously with the table body 310 to above the lower mold 431. It should be noted that in the actual processing, glue is coated on the lower mold 431. During the waiting process for covering the skin, the bonding force of the glue will gradually decrease as its solidification degree increases. Therefore, the lamp tube module 340 is required to heat and bake it to activate the glue. Further, in order to adapt to different lower molds 431, it is often necessary to frequently replace different lamp tube modules 340 so that the glue can be in an optimal state during the skin covering process.

[0047] Refer to Figures 9 to 11 As shown, the laminating mechanism 400 in this embodiment includes a laminating frame 410, an upper mold assembly 420, and a lower mold assembly 430. The lower mold assembly 430 is fixed to the bottom of the laminating frame 410, and the upper mold assembly 420 is slidably connected to the laminating frame 410. Among them, the upper mold assembly 420 moves up and down above the lower mold assembly 430, and the composite function table 300 can be moved between the upper mold assembly 420 and the lower mold assembly 430 through the transmission mechanism 200 so that the lamp tube module 340 approaches the lower mold 431 after glue application. Among them, the upper mold assembly 420 includes a plurality of first one-way plug-in columns 424, and the lower mold assembly 430 includes a plurality of second one-way plug-in columns 433. The first one-way plug-in columns 424, the two-way plug-in column 320, and the second one-way plug-in columns 433 can be plugged into each other to form a support connection structure among the three.

[0048] Further, the upper mold assembly 420 in this embodiment includes a mounting plate 423, an upper mold 421, a lifting driver 425, and a plurality of material transfer jaws 422. The lifting driver 425 is fixed to the top of the laminating frame 410, and its working end is connected to the center of the mounting plate 423. The upper mold 421 is arranged on the mounting plate 423, and a plurality of the material transfer jaws 422 are arranged around the upper mold 421. Among them, the mounting plate 423 provides an installation and connection platform for the upper mold 421 and the material transfer jaws 422, and a plurality of the material transfer jaws 422 are used to clamp and transfer the skin material 500 to be laminated on the table body 310. After the material transfer jaws 422 clamp the edge of the skin material, the skin pulling jaws 332 will release the skin material, so that the skin material can move with the upper mold assembly 420 to above the lower mold assembly 430. Specifically, the lifting driver 425 in this embodiment is preferably a linear motor.

[0049] In this embodiment, the first one-way insertion post 424 extends from the mounting plate 423 towards the lower die assembly 430. Among them, the first one-way insertion post 424 extends along the moving direction of the upper die assembly 420. The first one-way insertion post 424 includes a second body 4241 and a second insertion bump 4242. The second insertion bump 4242 protrudes from the second body 4241 towards the two-way insertion post 320 to be inserted into the first insertion slot 323, thereby forming a mating insertion relationship between the table 310 and the upper die assembly 420.

[0050] Correspondingly, the lower die assembly 430 in this embodiment includes a support table 432 and a lower die 431. The lower die 431 is arranged on the support table 432. The second one-way insertion post 433 extends from the support table 432 towards the upper die assembly 420. Further, the second one-way insertion post 433 extends along the moving direction of the upper die assembly 420. It includes a third body 4331 and a second insertion slot 4332. The second insertion slot 4332 is recessed from the top surface of the third body 4331 for the first insertion bump 322 to be inserted, thereby forming a mating insertion relationship between the table 310 and the lower die assembly 430. Embodiment Two

[0051] This embodiment provides a method for leather composite with replaceable mode, which uses the leather composite device with replaceable mode described in Embodiment One to perform leather composite processing and die replacement. Among them,

[0052] The die replacement method includes:

[0053] Step a: Move the table with a kind of lamp module between the upper die and the lower die through the transmission mechanism;

[0054] Step b: Drive the table to approach the lower die assembly through the transmission mechanism until one end of the two-way insertion post connected to the table is inserted into the second one-way insertion post of the lower die assembly;

[0055] Step c: Disconnect the table from the transmission mechanism and make the transmission mechanism return to the initial position. In this embodiment, the table and the transmission mechanism are detachably connected, and the operator can disconnect the table from the transmission mechanism by removing screws or other means.

[0056] Step d: Drive the upper die assembly to approach the table until the first one-way insertion post of the upper die assembly is inserted into the other end of the two-way insertion post, so as to form a support connection structure among the first one-way insertion post, the two-way insertion post and the second one-way insertion post;

[0057] Step e: Clamp the table body with an external handling device. After stabilization, drive the upper mold mechanism away from the table body, and synchronously lift the table body by the external handling device until the first one-way insertion column and the second one-way insertion column are disengaged from the two-way insertion column respectively.

[0058] Step f: Transfer the table body with the external handling device. At the same time, assemble a table body with another type of lamp module on the transmission mechanism after the external handling device returns to the initial position. Thus, the mold change is completed. Among them, the external handling device is preferably a transfer robot, and the present invention does not make specific restrictions on this.

[0059] Based on the above process, in the present application, the disassembly and transfer of the old mold and the assembly and connection of the new mold can be achieved simultaneously without additional waiting beats, thereby significantly improving the mold change efficiency.

[0060] The leather composite processing method includes:

[0061] Step S1: Transport the table body connected with the leather to be composite and the lamp module between the upper mold and the lower mold, and set the leather to be composite facing the upper mold assembly and the lamp module facing the lower mold assembly. It should be noted that before step S1, the rolled leather to be processed needs to be fed, roll-pressed, leather traction transported and cut in sequence to obtain the leather to be composite.

[0062] Step S2: After the table body approaches the lower mold coated with glue, activate the glue on the surface of the lower mold through the lamp module.

[0063] Step S3: Drive the lamp component to move by the table body to avoid the moving path of the upper mold assembly.

[0064] Step S4: Drive the upper mold assembly to move towards the lower mold assembly until the leather to be composite is pressed between the upper mold and the lower mold, and the leather composite process is completed.

[0065] In summary, for the replaceable-mode leather composite device and method of the present invention, the leather to be processed can be supplied through the transmission mechanism, the leather and the lamp tube module can be driven to move by the composite function table, and the leather and the mold body can be pressed through the composite mechanism, thereby realizing the leather composite processing process. When it is necessary to change the mold, a stable support connection structure that can be mutually inserted can be formed among the first one-way insertion column, the two-way insertion column, and the second one-way insertion column, and the composite function table can also be separately transferred by an external handling device through its detachable connection structure with the transmission mechanism. Therefore, not only can the synchronous replacement of new and old molds be realized, but also the transfer safety level can be improved, and the transfer damage to components can be reduced. Compared with the current conventional leather composite technology, this application has significant advantages such as high structural cooperation degree, reasonable layout, strong flexibility in use, high mold-changing efficiency, and extendable service life of the equipment, providing new ideas and directions for the improvement of leather composite technology.
