In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] The present invention provides a method for splicing soft materials, including the following steps:

[0031] Step 1: Through vacuum adsorption, the protective film drives two pieces of soft material A to present an arc-shaped convex state, so that the contact surfaces of the two pieces of soft material A tilt towards both sides, and thus a splicing position appears at the position where the two pieces of soft material A are in contact.

[0032] Step 2: Press the splicing material B into the splicing position between the two pieces of soft material A, release the vacuum adsorption on the protective film, so that the protective film drives the two pieces of soft material A to return to their original state, thereby clamping the splicing material B and fixing the splicing material B between the two pieces of soft material A.

[0033] In this embodiment, a splicing position appears between the two pieces of soft material A through vacuum adsorption, and then the splicing material B is pressed into the splicing position. After releasing the vacuum adsorption, the splicing material B is spliced into the splicing position of the two pieces of soft material A, overcoming the problem that when splicing by the traditional splicing method, since the splicing material first contacts the upper surface of the soft material, the splicing material easily presses the upper surface of the soft material into the splicing position, resulting in wrinkles after splicing the soft materials and causing the splicing to be not firm.

[0034] In a specific embodiment, the following steps are further included before the step 1:

[0035] Step 10: Select the soft material A to be spliced and measure the maximum deformation value of the splicing material A;

[0036] Step 11: Fix and bond the two pieces of soft material A to be spliced tightly next to each other on the protective film, so that the two pieces of soft material A are joined together.

[0037] In this embodiment, by measuring the maximum deformation value of the splicing material A, that is, the maximum deformation value that the soft material A can still recover in the stretched state, the deformation amount of the soft material A is controlled not to exceed this deformation value during subsequent vacuum pumping, preventing the soft material from being unable to recover after being stretched, and thus unable to clamp the splicing material B and failing to achieve the splicing effect; two soft materials A are fixedly bonded to the protective film closely, so that when the two soft materials A are opened at the splicing position by vacuum pumping, the two soft materials A can remain relatively stable, and after losing the effect of vacuum pumping, they can clamp the splicing material B by the squeezing force of recovery.

[0038] In a specific embodiment, in the step 10, the tools used to measure the maximum deformation value of the splicing material A are a tensile machine and a length measuring instrument. During specific testing, the tensile machine is used to pull the opposite ends of the soft material A in opposite directions and continuously measure its stretched length with the length measuring instrument. When the tensile machine releases the pulling of the soft material A and the soft material A cannot recover, the length of the stretched soft material A measured at this time minus the length of the soft material A when it is not pulled is the maximum deformation value of the soft material A.

[0039] In a specific embodiment, in the step 11, the sum of the horizontal lengths of the two soft materials A inclined to both sides is not greater than the maximum deformation value of the soft material A, so that the two soft materials A can clamp the splicing material B after being stretched and recovered, thus ensuring the tightness of the splicing.

[0040] As Figures 1-4 shown, the present invention also provides a soft material splicing device, including a frame 1, a conveying mechanism 2 installed on the frame 1 for conveying materials, a stretching mechanism 3 installed on the conveying mechanism 2 for stretching the soft material A, and a pressing mechanism installed on the frame 1 for pressing the splicing material B into the soft material A; the stretching mechanism 3 includes a stretching base 31 installed on the conveying mechanism 2, an adsorption component installed on the stretching base 31, a stretching station arranged at the upper end of the adsorption component, and a stretching component connected to the stretching station for driving the stretching station to move so as to stretch the product.

[0041] In this embodiment, the soft material A to be spliced is placed on the stretching station, and the soft material A to be spliced is firmly adsorbed on the stretching station by the adsorption component and conveyed by the conveying mechanism 2 to the lower part of the pressing mechanism. Then, the stretching component drives the stretching station to change from a horizontal state (such as Figure 3 ) to an arc-shaped convex state (such as Figure 4), at this time, due to the adsorption of the soft material A by the adsorption component, the soft material A is also subjected to a stretching effect, so that the side surface of the splicing position of the soft material A tilts outward and opens, so that the splicing position of the soft material A can be opened, making the splicing space of the soft material A larger. At this time, the splicing material B is pressed into the splicing position of the soft material A by the pressing component, and the stretching component restores the stretching station, so that the stretching station changes from a downward inclined state to a horizontal state, so that the splicing space of the soft material A adsorbed on the stretching station returns to the initial state, so that the soft material A can firmly press the splicing material B inside the soft material A; specifically, in the product involved in the present invention, a protective film is laid at the lower end of the soft material A, so that the soft material A can still remain as a whole after being stretched. During the actual product manufacturing, first detect the deformation value of the soft material A under stretching (that is, the stretching degree value that can be restored after being stretched to the maximum extent), and the deformation value of the splicing material B is half of that of the soft material A. Therefore, after the splicing material B is pressed into the splicing position of the soft material A, the splicing material B will not be squeezed and deformed to form a bulge, thus ensuring the flatness of the product surface after splicing.

[0042] In a specific embodiment, the stretching station includes a first stretching block 321 respectively connected to the stretching component and a second stretching block 322 movably connected to the first stretching block 321; a first placement groove is provided on the first stretching block 321; a second placement groove is provided on the second stretching block 322; the first placement groove and the second placement groove together form a product groove 323 for placing products; in this embodiment, the connector between the first stretching block 321 and the second stretching block 322 is provided with a rotating shaft. In the initial state (that is, the surface where the first stretching block 321 and the second stretching block 322 are connected is in a horizontal state), there is an avoidance space 3231 at the connection position of the first stretching block 321 and the second stretching block 322 (such as Figure 3 ), so that under the drive of the stretching component, the first stretching block 321 and the second stretching block 322 can close downward, so that the surface formed by the first stretching block 321 and the second stretching block 322 forms an arc-shaped convex state, thereby driving the soft material A adsorbed in the product groove 323 to also form an arc-shaped convex state, and the splicing position is just located at the vertex position of the convexity, so that the side surface of the splicing position tilts outward, and then the space of the splicing position becomes larger, so that when the splicing material B is pressed into the splicing position, it will not contact the edge of the splicing position, so that the spliced complete product will not produce wrinkles.

[0043] In an alternative embodiment, the stretching station can also be integrally formed of a soft material, so that under the drive of the stretching assembly, it can change from a horizontal state to an upwardly convex arc state. The stretching station is provided with a plurality of adsorption holes, so that under the action of the vacuum pump, the soft material A can be adsorbed.

[0044] In a specific embodiment, the stretching base 31 is provided with a plurality of first adsorption holes; a plurality of second adsorption holes 3232 communicating with the first adsorption holes are provided in the product groove 323; the adsorption assembly includes a vacuum pump disposed at the upper end of the stretching base 31 and connected to the first adsorption holes; in this embodiment, the vacuum pump can evacuate the first adsorption holes and the second adsorption holes 3232, so that the soft material A to be spliced can be firmly adsorbed on the product groove 323, and further the soft material A can be stretched as the product groove 323 is stretched.

[0045] In a specific embodiment, the stretching assembly includes a first stretching assembly installed at one end of the stretching base 31 and connected to the first stretching block 321 and a second stretching assembly installed at the other end of the stretching base 31 and connected to the second stretching block 322; the first stretching assembly is used to pull the first stretching block 321 up and down, and the second stretching assembly is used to pull the second stretching block 322 up and down. Thus, under the cooperation of the first stretching assembly and the second stretching assembly, the product groove 323 formed by the first stretching block 321 and the second stretching block 322 can be switched between a horizontal state and an arc-shaped convex state, facilitating splicing.

[0046] In a specific embodiment, the first stretching assembly includes a first stretching power member 331 installed at one end of the stretching base 31 and a first stretching member 332 connected to the output end of the first stretching power member 331; the first stretching member 332 is connected to the first stretching block 321; the second stretching assembly includes a second stretching power member installed at the other end of the stretching base 31 and a second stretching member 341 connected to the output end of the second stretching power member; the second stretching member 341 is connected to the second stretching block 322; specifically, in the initial state, the first stretching block 321 and the second stretching block 322 slightly float above the upper end of the stretching base 31 under the connection action of the first stretching member 332, so that when stretching the soft material A, the first stretching block 321 and the second stretching block 322 have a downward movement space, and at this time, the upper surfaces of the first stretching block 321 and the second stretching block 322 are in a horizontal state. When splicing the splicing material B into the splicing position of the soft material A, the first stretching power member 331 and the second stretching power member simultaneously drive the first stretching member 332 and the second stretching member 341 to move downward, thereby driving the first stretching block 321 and the second stretching block 322 to descend, so that the product groove 323 formed by the first stretching block 321 and the second stretching block 322 forms an arc-shaped protrusion, which is convenient for splicing.

[0047] In a specific embodiment, the conveying mechanism 2 includes a conveying guide rail 21 installed on the frame 1, a conveying base slidably installed on the conveying guide rail 21, and a conveying power member for driving the conveying base to move directionally on the conveying guide rail 21; the stretching mechanism 3 is installed on the conveying base; in this embodiment, when transporting the soft material A, the conveying power member drives the conveying base to drive the stretching mechanism 3 to move directionally on the conveying guide rail 21, so that the soft material A can be conveyed to the lower end of the pressing mechanism or sent away from the pressing mechanism for blanking.

[0048] In a specific embodiment, the material pressing mechanism includes a material pressing frame 41 installed on the frame 1, a downward pressing power member 42 installed on the material pressing frame 41, and a downward pressing member 43 connected to the output end of the downward pressing power member 42; an air suction pipe 44 is provided on the downward pressing member 43; the air suction pipe 44 is connected to an air suction machine; in this embodiment, when it is necessary to adsorb the splicing material B, the downward pressing power member 42 drives the downward pressing member 43 to press down, so that the air suction pipe 44 contacts the splicing material B. Under the adsorption action of the air suction machine, the air suction pipe 44 can adsorb the splicing material B and drive it to rise by the downward pressing power member 42. When the soft material A is stretched by the stretching mechanism 3, the downward pressing power member 42 drives the downward pressing member 43 to drive the adsorbed splicing material B to press down, so as to press the splicing material B into the splicing position of the soft material A, and thus complete the splicing under the action of the stretching mechanism 3.
