[0009] Step 2) flannel edging: spray glue on one side of the flannel, and then stick the flannel to the edge of the cushion plate; wherein the flannel is not attached to the front end of the cushion plate;

[0010] Step 3) One-time lamination of sponge pads: spray glue on the top of the cushion plate, wherein the angle iron is also sprayed with glue; then the first sponge pad, the second sponge pad, the third sponge pad and the fourth sponge pad are affixed to the cushion plate; wherein the first sponge pad is affixed to the left side of the cushion plate, and part of the first sponge pad is pressed on the first folded edge of the angle iron on the left side, the second sponge pad is affixed to the right side of the cushion plate, and part of the second sponge pad is pressed on the first folded edge of the angle iron on the right side, the third sponge pad is affixed to the rear side of the cushion plate, and part of the third sponge pad is pressed on the flannel, and the fourth sponge pad is affixed to a position between the first sponge pad and the second sponge pad on the cushion plate;

[0011] Step 4) Secondary bonding of the sponge pads: spray glue on the first sponge pad, the second sponge pad, the third sponge pad and the fourth sponge pad; then stick the middle sponge pad on the fourth sponge pad, and then stick the U-shaped covering sponge pad on the first sponge pad, the second sponge pad and the third sponge pad; wherein the middle sponge pad fills the middle opening of the U-shaped covering sponge pad;

[0012] Step 5) Remove the assembled sponge cushion from the positioning plate.

[0013] Preferably, in step 1), the cushion plate is fixed on the positioning plate; wherein the positioning plate is mounted on the base plate in a manner that allows it to be raised, lowered and rotated.

[0014] Preferably, a plurality of suction cups are provided on the positioning plate, and the plurality of suction cups are all connected to the air pump; in the step 1), when the seat cushion plate is fixed on the positioning plate, the plurality of suction cups jointly support the seat cushion plate, and then the air pump is started to adsorb the seat cushion plate through the plurality of suction cups, thereby fixing the seat cushion plate on the positioning plate.

[0015] Preferably, a second cylinder is installed on the positioning plate, and a third through hole is opened in the central position of the positioning plate; in the step 5), after the sponge cushion is assembled, the air pump stops running, the suction cup loses its adsorption force, and the telescopic end of the second cylinder extends from the third through hole of the positioning plate, pushing the cushion plate to separate from the suction cup.

[0016] Preferably, a traction clamp, a second glue gun and a roller are also installed on the bottom plate; in the step 2), the traction clamp clamps one end of the flannel; then, the traction clamp moves and drives the flannel to pass through the second glue gun, and the second glue gun sprays glue on one side of the flannel; then the traction clamp moves toward the cushion plate, so that the side of the flannel sprayed with glue is against the edge of the cushion plate; then the end of the flannel is fixed to the edge of the cushion plate, and the traction clamp releases the flannel; then the roller approaches the cushion plate, and the roller pushes the flannel, so that the glue-coated side of the flannel is bonded to the edge of the cushion plate, and the positioning plate is rotated to make the flannel gradually stick to the edge of the cushion plate.

[0017] Preferably, a sixth cylinder is installed on the positioning plate, and a bonding plate is fixed to the telescopic end of the sixth cylinder, and the bonding plate is vertically arranged and located on the outside of the cushion plate; in the step 2), when the traction clamp pulls the flannel cloth to pass between the cushion plate and the bonding plate, the sixth cylinder starts and drives the bonding plate to approach the cushion plate, so that the bonding plate and the cushion plate clamp the flannel cloth, thereby fixing the flannel cloth and the cushion plate.

[0018] Preferably, the flannel is wound in the form of a flannel roll, and a cutting knife capable of being raised and lowered is installed on the bottom plate; in the step 2), the traction claw pulls the flannel on the flannel roll to unfold it and passes it through the second glue gun. When the length of the glue-sprayed part on the flannel reaches a preset length, the cutting knife in a rotating state moves up and down to cut the flannel.

[0019] Preferably, the base plate is installed with a first clamping plate, a second clamping plate and a fourth cylinder, the first clamping plate is fixed on the base plate, the fourth cylinder is connected to the second clamping plate and can drive the second clamping plate to approach or move away from the first clamping plate; in the step 2), one end of the flannel extends from the first clamping plate and the second clamping plate, and the traction claw clamps the part of the flannel extending from the first clamping plate and the second clamping plate; when the length of the glue-sprayed part on the flannel reaches a preset length, the fourth cylinder drives the second clamping plate to approach the first clamping plate, thereby clamping the flannel, and then the flannel cutting mechanism cuts the part of the flannel extending from the first clamping plate and the second clamping plate.

[0020] Preferably, a sixth mounting seat is fixed on the base plate, a slider is slidably mounted on the sixth mounting seat, the roller is vertically arranged and rotatably mounted on the slider, a seventh cylinder is also mounted on the base plate, the telescopic end of the seventh cylinder is connected to the slider and can drive the slider to approach or move away from the positioning plate; in the step 2), the seventh cylinder drives the roller to approach the seat cushion plate, so that the flannel cloth gradually sticks to the edge of the seat cushion plate, and then the seventh cylinder drives the roller to move back and forth, so that the moving trajectory of the roller matches the contour of the seat cushion plate.

[0021] Preferably, a first glue gun is also installed on the base plate, and the first glue gun is located above the cushion plate; in the steps 3) and 4), glue is sprayed on the cushion plate, the first sponge pad, the second sponge pad, the third sponge pad and the fourth sponge pad by moving the first glue gun on the cushion plate.

[0022] The beneficial effects of the technical solution of the present invention are as follows: the sponge used to support the human body on the above-mentioned chair cushion is divided into two parts, one is a U-shaped covering sponge pad, and the other is a middle sponge pad filled with the inner side of the sponge pad, and the hardness of the covering sponge pad is greater than that of the middle sponge pad, and the two sponge pads are not bonded to each other, so that when the user sits on the cushion, the covering sponge pad and the middle sponge pad can be separated, so that the middle position of the contact part of the human body with the cushion is supported by the softer sponge pad, while the outer position of the contact part of the human body with the cushion is supported by the harder sponge pad. With the support of the sponge pad, the sponge pad will not pull the user's pants outward when the user uses the seat cushion, which can improve the comfort of the seat cushion; secondly, the covering sponge pad and the middle sponge pad are not directly bonded to the seat cushion plate, but are bonded to the seat cushion plate through multiple small thin pads. This not only ensures the bonding strength of the middle sponge pad and the covering sponge pad, but also facilitates the separation of the assembled chair cushion if the assembled chair cushion is unqualified, thereby reducing the impact on the seat cushion plate, the middle sponge pad and the covering sponge pad, allowing them to be reused and reducing production costs.
