[0103] The content of the application will be further described in detail below in combination with specific embodiments:

[0104] In order to facilitate understanding, the application scenario of the present application is first described, which is used for preparing a handle structure, including a paper handle in a paper-plastic product, which is formed by bonding a main material and a pair of side cards. In the present application, the main material is defined as base material 001, and the side card is defined as auxiliary material 002, as shown in Figure 1 As shown, the base material 001 needs to be bent at both ends, as shown in Figure 2 The auxiliary material 002 needs to be bonded with the base material 001 and bent in the opposite direction. The forming process involves cutting, bending, dispensing, bubble removing and other operations.

[0105] In combination with Figure 3 , Figure 4 As shown, the material bonding machine provided in the present application includes a conveying assembly 1, a plurality of carrier assemblies 2, a base material feeding assembly 3, a dispensing assembly 5, an auxiliary material feeding assembly 6, and at least one pre-folding assembly.

[0106] The conveying assembly 1 is arranged along a preset first direction, i.e. the X-axis direction as shown in Figure 3 As shown, the X-axis direction, in combination with Figure 4As shown, the conveying pipeline 1 adopts a speed chain structure, and sequentially corresponds to the base material loading station 01, the dispensing station 03, the auxiliary material loading station 04, at least one pre-folding station, and the unloading station 07 along the conveying direction.

[0107] The carrier assembly 2 moves synchronously along the conveying pipeline 1. Since the conveying pipeline 1 adopts a speed chain structure, the carrier assembly 2 is placed on the speed chain, thereby forming a "speed chain-carrier" structure, and the carrier assembly 2 moves with the movement of the speed chain. The base material loading assembly 3 is arranged near the base material loading station 01 and sequentially supplies the base material to the carrier assembly 2 at the base material loading station 01. The dispensing assembly 5 is arranged above the carrier assembly 2 at the dispensing station 03 and dispenses at least one end of the non-pre-folding area of the base material. The auxiliary material loading assembly 6 supplies the auxiliary material to the carrier assembly 2 at the auxiliary material loading station 04 and adheres the auxiliary material to the base material after dispensing in the carrier assembly 2. The pre-folding assembly is arranged at least on one side of the pre-folding station and cooperates with the carrier assembly at the pre-folding station to pre-fold the base material and / or the auxiliary material and obtain a molded part.

[0108] It can be understood that the pre-folding assembly can complete the pre-folding of the base material and the auxiliary material at one time, or can pre-fold the base material and the auxiliary material at least twice.

[0109] Specifically, as shown in Figure 5 The conveying pipeline 1 is further provided with a reflow pipeline 11 below, and the reflow pipeline 11 is arranged along the first direction. The conveying pipeline 1 and the reflow pipeline 11 are respectively provided with a reflow assembly 12 on both sides along the first direction, as shown in Figure 6 The reflow assembly 12 includes a reflow seat 121 and a reflow jacking assembly 122 for driving the reflow seat 121 to lift. The reflow assemblies 12 on both sides respectively transfer the carrier assembly 2 at the end of the conveying pipeline 1 to the starting end of the reflow pipeline 11, and transfer the carrier assembly 2 at the end of the reflow pipeline 11 to the starting end of the conveying pipeline 1.

[0110] In Figure 5As shown, the orientation is taken as an example, the conveying pipeline 1 is set to rotate clockwise, that is, the upper end surface movement direction is from left to right; the return pipeline 11 is set to rotate counterclockwise, that is, the upper end surface movement direction is from right to left; the return assembly 12 on the left side moves in the clockwise direction when its height is the same as the height of the conveying pipeline 1, and moves in the counterclockwise direction when its height is the same as the height of the return pipeline 11; the return assembly 12 on the right side moves in the clockwise direction when its height is the same as the height of the conveying pipeline 1, and moves in the counterclockwise direction when its height is the same as the height of the return pipeline 11. Therefore, the rotation direction of the return seat 121 is always the same as the rotation direction of the pipeline at the same height. Based on the setting of the conveying pipeline 1, the return pipeline 11, and a pair of return jacking assemblies 122, the carrier assembly 2 moving from the base material feeding station 01 to the discharging station 07 can smoothly return in the opposite direction to the side close to the base material feeding station 01, and the transfer of the carrier assembly 2 between the conveying pipeline 1 and the return pipeline 11 is realized based on the setting of the return assembly 12, and finally the efficient flow of the carrier assembly 2 is realized.

[0111] As shown in the figure, Figure 7 the carrier assembly 2 is arranged in turn corresponding to each station, and moves synchronously along the conveying pipeline 1, and the displacement amount of the carrier assembly 2 between adjacent stations is equal, which meets the synchronous movement requirement of multiple carrier assemblies 2, and cooperates with each assembly to perform actions synchronously between stations.

[0112] As shown in the figure, Figure 8 the carrier assembly 2 includes a carrier carrier 21, and the carrier carrier 21 has a plurality of accommodation grooves 211 for placing the base material 001 and the auxiliary material 002, and the accommodation grooves 211 are arranged perpendicular to the first direction in the horizontal plane; at least one side of each accommodation groove 211 is provided with a displacement prevention member 22 for positioning the base material 001; the displacement prevention member 22 has an upper limit station and a lower limit station, and the displacement prevention member 22 is in the upper limit station in the normal state and acts on the material in the accommodation groove 211 to prevent the material from shifting or falling during the transfer process.

[0113] Specifically, as shown in the figure, Figure 9 the carrier carrier 21 has a mounting chamber 212 between adjacent accommodation grooves 211, the displacement prevention member 22 is arranged in the mounting chamber 212, and includes a carrier shaft 221, a plurality of pairs of flaps 222 sleeved on the carrier shaft 221, and a torsional spring 223 arranged between each pair of flaps 222; the carrier shaft 221 is normally at the uppermost end of the mounting chamber 212, that is, Figure 9 as shown in the figure, one end of a pair of flaps 222 abuts against the side of the accommodation groove 211, and then is used for positioning the material placed in the accommodation groove 211 to prevent displacement.

[0114] In the embodiment, the carrier assembly 2 at the base material feeding station 01 and the base material discharging station 07 is respectively provided with an opening and closing assembly 23 on both sides perpendicular to the first direction, the opening and closing assembly 23 drives the anti-displacement member 22 to switch to the lower limit station for feeding or discharging the material; at other stations between the base material feeding station 01 and the base material discharging station 07, the flap 222 always presses against the material.

[0115] As shown in Figure 10 , the opening and closing assembly 23 includes a plurality of rollers 231 and an opening and closing drive 232 for driving the same side rollers 231 to move synchronously; each roller 231 is arranged at the side of the carrier shaft 221, and the height of the central axis of the roller 231 is higher than the height of the central axis of the carrier shaft 221; when the roller 231 is extended by the action of the opening and closing drive 232, it pushes the carrier shaft 221 to move downward along the mounting chamber 212 and drives the flap 222 to overturn the mounting chamber 212 against the action of the torsional spring 223, thereby releasing the positioning of the material in the containing groove 211 by the flap 222. It can be understood that, as shown in Figure 9 , Figure 11 , when the anti-displacement member 22 is at the upper limit station, a pair of flaps 222 form a V-shaped structure with the opening downward; during the gradual downward movement of the carrier shaft 221, a pair of flaps 222 become a V-shaped structure with the opening upward, and as the carrier shaft 221 continuously moves downward, the opening of a pair of flaps 222 gradually becomes smaller, and the flap 222 can be realized without acting on the side of the containing groove 211, thereby releasing the positioning of the material by the anti-displacement member 22.

[0116] In order to facilitate the cooperation of the carrier assembly 2 with other assemblies, the carrier assembly 2 is provided with a carrier jacking assembly 24 below any station, as shown in Figure 11 , the carrier jacking assembly 24 includes a jacking plate 241 and a jacking drive 242, the jacking plate 241 is inserted below the carrier carrier 21 and is separated from the support of the conveying line 1 by the action of the jacking drive 242; the carrier assembly 2 is provided with a check member 25 and a stop member 26 on both sides of any station along the first direction; the check member 25 and the stop member 26 are limited by the side wall of the carrier carrier 21. By providing the jacking assembly 24, the check member 25 and the stop member 26, the stability of the cooperation of the carrier assembly 2 with other assemblies is satisfied, and at the same time, the damage and failure of the conveying line 1 due to long-time overloading can be avoided.

[0117] As shown in Figure 3 , Figure 4 , the base material feeding assembly 3 is arranged on one side deviated from the base material feeding station 01 to sequentially feed the base material 001 to the carrier assembly 2 at the base material feeding station 01.

[0118] Specifically, as shown in Figure 12 , the base material feeding assembly 3 includes a base material feeding device 31 and a base material feeding guide 32; the base material feeding device 31 is arranged on the conveying line 1 and is used to feed the base material 001 to the base material feeding guide 32; the base material feeding guide 32 is arranged on the conveying line 1 and is used to guide the base material 001 to the base material feeding station 01.As shown, the base material loading assembly 3 includes a base material feeding disc 31, a guide assembly 32, a fixed-length feeding assembly 33, a cutting assembly 34, a base material positioning assembly 35, and a base material loading driving member 36 arranged in sequence along the first direction.

[0119] The number of the base material feeding disc 31 is consistent with the number of the accommodation grooves 211 in the carrier carrier 21, and the plurality of base material feeding discs 31 are arranged staggered in the top view direction. In this embodiment, the number of the accommodation grooves 211 is set to four, and the number of the base material feeding discs 31 is the same.

[0120] As shown, Figure 13 The guide assembly 32 includes a plurality of first guide wheels 321 for guiding the material released by the base material feeding disc 31 to ensure that the material can smoothly enter the fixed-length feeding assembly 33. In an embodiment, the first guide wheels 321 are arranged in two groups and distributed along the first direction (X-axis direction), and the axial direction is perpendicular to the first direction. The material is sequentially wound around the two groups of first guide wheels 321 and enters the fixed-length feeding assembly 33.

[0121] As shown, Figure 13 The fixed-length feeding assembly 33 includes a feeding bottom die 331, a feeding upper die 332, and a linear motion module 333 for driving the feeding bottom die 331 and the feeding upper die 332 to move synchronously. The feeding bottom die 331 and the feeding upper die 332 clamp the material and are driven by the linear motion module 333 to convey a fixed length of the material to the cutting assembly 34.

[0122] As shown, Figure 13 The cutting assembly 34 includes a cutting upper die 341, a cutting lower die 342, an upper die cutting knife 343, and a lower die cutting knife 344 for cutting the material and obtaining a fixed-length base material 001, which is positioned in the base material positioning assembly 35.

[0123] The base material positioning assembly 35 has the same number of positioning grooves 351 as the accommodation grooves 211. After the material is accommodated in the positioning groove 351, the cutting assembly 34 performs the cutting action to obtain the base material 001. The length direction of each base material 001 in the positioning groove 351 is arranged along the first direction, and the plurality of base materials 001 are arranged perpendicular to the first direction.

[0124] As shown, Figure 12 The base material loading driving member 36 adopts a four-axis robot, and the movable end of the four-axis robot is provided with a vacuum chuck for synchronously grabbing the plurality of base materials 001 in the base material positioning assembly 35 and placing them in the accommodation grooves 211 of the carrier assembly 2 in the loading station. Since the length direction of each accommodation groove 211 is arranged perpendicular to the first direction, the four-axis robot needs to rotate the posture of the base material 001 by 90° during the transfer of the base material 001.

[0125] In an embodiment, the base material is pre-folded at both ends by a one-time pre-folding assembly 4, and the one-time pre-folding assembly is provided with a one-time pre-folding station 02. The one-time pre-folding station 02 is located between the base material feeding station 01 and the dispensing station 03.

[0126] The one-time pre-folding assembly 4 is symmetrically arranged on both sides of the one-time pre-folding station 02, and cooperates with the carrier assembly 2 at the one-time pre-folding station 02 to complete the downward pre-folding of both ends of the base material 001.

[0127] As shown in Figure 14 , the one-time pre-folding assembly 4 includes a one-time pre-folding block 41 and a one-time pre-folding driving member 42 for driving the one-time pre-folding block 41 to move. The one-time pre-folding block 41 is provided with a gap below, and the one-time pre-folding driving member 42 drives the one-time pre-folding block 41 to move in an oblique direction, so that a set of vertical end faces corresponding to the gap simultaneously act on the accommodation groove 211 and the side wall of the carrier carrier 21, thereby bending both ends of the straight strip-shaped base material 001 downward, and the base material 001 is pre-folded and formed as shown in Figure 1 .

[0128] The dispensing assembly 5 is arranged above the carrier assembly 2 at the dispensing station 03 to dispense glue on both ends of the non-pre-folded structure of the base material 001. The dispensing assembly 5 is provided with two sets, and the two sets of dispensing assemblies 5 are arranged on the same bracket or on two brackets.

[0129] In an embodiment, the dispensing assembly 5 is arranged on two brackets. Taking one of the brackets as an example, as shown in Figure 15 , each set of dispensing assemblies 5 includes a plurality of dispensing guns 51 and a dispensing driving member 52 for driving the plurality of dispensing guns 51 to move synchronously along the length direction of the accommodation groove 211. Each dispensing gun 51 is arranged above the end of the accommodation groove 211 in sequence to dispense glue on both ends of the non-bent area of the base material 001 after pre-folding. The dispensing gun 51 arranged on the other bracket is arranged above the other end of the accommodation groove 211. Thus, the two sets of dispensing assemblies 5 are respectively used to dispense glue on both ends of the non-bent area of the base material 001, and the process of cooperating with other assemblies to move is fast and efficient.

[0130] As shown in Figure 16 , the auxiliary material feeding assembly 6 includes an auxiliary material feeding disc 61, a punching and conveying assembly 62, and a carrying assembly 63. As shown in Figure 4 , the auxiliary material feeding disc 61 and the punching and conveying assembly 62 are provided with two sets and are arranged on both sides of the conveying assembly 1 perpendicular to the first direction. The carrying assembly 63 is arranged above the conveying assembly 1. Based on the cooperation of the auxiliary material feeding disc 61, the punching and conveying assembly 62, and the carrying assembly 63, the auxiliary material 002 is sequentially fed to the carrier assembly 2 at the auxiliary material feeding station 04 and adhered to the dispensing position of the base material 001 after dispensing.

[0131] As shown in Figure 17 , Figure 18 , the auxiliary material feeding tray 61 is used to arrange the material, and a plurality of second guide wheels 611 are arranged on the side edges, and a pair of pressure rollers 612 are arranged at the material output end, the pair of pressure rollers 612 press the end of the material, and the material is guided and conveyed to the punching and conveying assembly 62 through the synchronous rotation of the pair of pressure rollers 612.

[0132] As shown in Figure 17 , the punching and conveying assembly 62 includes a punching member 621, a linear vibration tray 622, a transfer member 623, and a conveying member 624.

[0133] The punching member 621 includes a punching lower die 6211 and a punching upper die 6212, which are used to punch and form the material to obtain the auxiliary material 002, and the punched and formed auxiliary material 002 is pushed onto the linear vibration tray 622 as the material between the pair of pressure rollers 612 is continuously supplied. In order to obtain auxiliary materials 002 of specific specifications, excess material may be generated during the punching and forming process, so a guide groove is arranged below the corresponding punching lower die 6211 to guide the excess material out.

[0134] The linear vibration tray 622 is arranged at the downstream end of the punching member 621 along the material conveying direction, the end abuts the outer wall of the punching lower die 6211, and the upper end surface of the linear vibration tray 622 is not higher than the height of the upper end surface of the punching lower die 6211, so that the auxiliary material 002 on the punching lower die 6211 can be smoothly pushed onto the linear vibration tray 622, and through the action of the linear vibration tray 622, the auxiliary material 002 can be orderly arranged therein, facilitating subsequent material taking by the conveying member 624.

[0135] The transfer member 623 is arranged on the side of the punching member 621 and the linear vibration tray 622, and includes a positioning carrier 6231 and a transfer module 6232 that drives the positioning carrier 6231 to move in a first direction; the positioning carrier 6231 has a positioning cavity 6233 for accommodating the auxiliary material 002, the number of positioning cavities 6233 is the same as the number of accommodation grooves 211, and a plurality of positioning cavities 6233 are arranged in the first direction, and the auxiliary material 002 in the adjacent positioning cavities 6233 can be placed in the adjacent accommodation grooves 211.

[0136] The conveying member 624 includes a conveying jig 6241 and a conveying module 6242 that drives the conveying jig 6241 to move; the conveying jig 6241 adopts a suction cup structure to pick up the auxiliary material 002 at the terminal end of the linear vibration tray 622 and sequentially transfer it into the positioning cavity 6233. In an embodiment, the conveying jig 6241 adopts a fixed-point dispensing method, so after placing one auxiliary material 002 into the positioning cavity 6233, the transfer module 6232 drives the positioning carrier 6231 to move one station until the positioning cavities 6233 in the positioning carrier 6231 all accommodate the auxiliary material 002.

[0137] The conveying assembly 63 is positioned above the conveyor line 1 and is arranged perpendicular to the first direction, such as... Figure 16 As shown, the transport assembly 63 includes a transport fixture 631 and a transport module 632 that drives the transport fixture 631 to move perpendicular to a first direction. The transport fixture 631 simultaneously picks up and transfers all auxiliary materials 002 in the positioning cavities 6233 to the end of the receiving groove 211, and bonds them to the base material 001 that has been applied with adhesive. After the auxiliary material 002 is placed in the receiving groove 211, its end extends out of the receiving groove 211. In one embodiment, each set of transport fixtures 631 uses the same number of vacuum suction cups as the positioning cavities 6233. Two sets of transport fixtures 631 are provided, one for transporting materials in the positioning cavities 6233 on the same side and placing them on the corresponding side of the receiving groove 211.

[0138] Since defoaming is required to ensure the tightness of the bond when bonding auxiliary material 002 with base material 001, a defoaming component 7 is set at the downstream end of the auxiliary material feeding component 6, and the defoaming component 7 has a corresponding defoaming station 05.

[0139] The defoaming component 7 is located downstream of the auxiliary material feeding component 6 along the direction of movement of the conveyor line 1; the defoaming component 7 works with the carrier component 2 at the defoaming station 05 to complete the defoaming at the bonding position of the base material 001 and the auxiliary material 002.

[0140] like Figure 19 As shown, the defoaming assembly 7 includes multiple pressure blocks 71 and a pressure-holding drive component 72 that drives the pressure blocks 71 to rise and fall. Each pressure block 71 is positioned directly above the receiving groove 211 and is embedded into the receiving groove 211 by the pressure-holding drive component 72, thereby pressing the base material 001 and auxiliary material 002 within the receiving groove 211 to complete defoaming and ensure the effective adhesion between the base material 001 and auxiliary material 002. It should be noted that, as... Figure 9 As shown, since the flap 222 in the anti-displacement component 22 acts at the middle position of the base material 001, the corresponding position of the pressure block 71 needs to avoid the flap 222.

[0141] After defoaming, the base material 001 and auxiliary material 002 are bonded together. The base material 001 is in a folded state, while the auxiliary material 002 is in a non-folded state. At this time, the auxiliary material 002 needs to be folded. Since the auxiliary material 002 needs to be folded upward, a secondary pre-folding component 8 is used, and there is a corresponding secondary pre-folding station 06.

[0142] The secondary pre-folding assembly 8 is symmetrically arranged on both sides of the secondary pre-folding station 06, cooperates with the carrier assembly 2 at the secondary pre-folding station 06 and the bubble removing assembly 7 to complete the upward pre-folding of the two ends of the auxiliary material 002, and finally obtains the formed piece. Therefore, in an embodiment, the bubble removing assembly 7 is arranged in two groups, one group is arranged at the bubble removing station 05, and the other group is arranged at the secondary pre-folding station 06, and cooperates with the secondary pre-folding assembly 8 to complete the pre-folding operation of the auxiliary material 002. In other embodiments, when the bubble removing assembly 7 is arranged in only one group, the bubble removing station 05 and the secondary pre-folding station 06 defined in the present application are coincident, that is, the bubble removing operation and the secondary pre-folding operation are both performed at the same station.

[0143] As shown in Figure 20 , the secondary pre-folding assembly 8 is combined with the bubble removing assembly 7, including a secondary pre-folding push piece 81 and a secondary pre-folding driving piece 82 for driving the movement of the secondary pre-folding push piece 81; the secondary pre-folding push piece 81 extends into the auxiliary material 002 below and moves in close contact with the pressing block 71 and the sidewall of the carrier carrier 21, so as to fold the auxiliary material 002 upward, and finally obtain the formed material as shown in Figure 2 .

[0144] The working principle of the present application is as follows:

[0145] a. Base material 001 feeding:

[0146] As shown in Figure 12 , Figure 13 , the uncut material is sequentially clamped between the feeding bottom die 331 and the feeding upper die 332 by the base material feeding disc 31 and the first guide wheel 321; after the material is clamped by the feeding bottom die 331 and the feeding upper die 332, it is driven by the linear motion module 333 to move from one side of the first guide wheel 321 to one side of the cutting assembly 34, thereby dragging the material to move a fixed length, and also making the fixed length of the material enter between the cutting upper die 341 and the cutting lower die 342, so as to realize the cutting of the material by the action of the upper die cutter and the lower die cutter, and obtain the base material 001 with a fixed length, which is positioned in the positioning groove 351; then, the four-axis manipulator simultaneously grasps multiple base materials 001 in the positioning groove 351, rotates the posture by 90°, and places them in the accommodation groove 211 of the carrier assembly 2 of the feeding station;

[0147] b. Base material 001 first pre-folding:

[0148] After the base material 001 is placed in the accommodation groove 211, both ends extend out of the accommodation groove 211, as shown in Figure 14 , the first pre-folding block 41 is driven by the first pre-folding driving piece 42 to press against the accommodation groove 211 and the sidewall of the carrier carrier 21, thereby realizing the downward bending of both ends of the base material 001, and obtaining the base material 001 as shown in Figure 1 .

[0149] c. dispensing treatment of the base material 001:

[0150] After the once pre-folding of the base material 001, the two ends of the base material 001 which are not folded are dispensed by the dispensing gun 51 as shown in the figure. Figure 15

[0151] d. auxiliary material 002 feeding:

[0152] As shown in the figure, Figure 17 , Figure 18 the uncut material is clamped between a pair of pressure rollers 612 by the auxiliary material feeding tray 61, and the end of the material is sent into the punching bottom die 6211 and the punching upper die 6212 by the rotation of the pressure rollers 612. The material is punched into the auxiliary material 002 by the action of the punching bottom die 6211 and the punching upper die 6212. The auxiliary material 002 is pushed onto the linear vibration tray 622 by the subsequent material entering the punching bottom die 6211 and the punching upper die 6212, and moves with the linear vibration tray 622. Then, the conveying jig 6241 picks up the material at the end of the linear vibration tray 622 and transfers it to the positioning cavity 6233. When all the positioning cavities 6233 are arranged with the auxiliary material 002, the handling jig 631 transfers all the materials in the positioning cavities 6233 to the end of the accommodation groove 211, which corresponds to the base material 001 which has been dispensed once after pre-folding, and realizes the adhesion of the two. At this time, the two ends of the auxiliary material 002 also extend to the outside of the accommodation groove 211.

[0153] e. debubbling between the base material 001 and the auxiliary material 002:

[0154] As shown in the figure, Figure 19 the multiple pressing blocks 71 are embedded in the accommodation groove 211 under the action of the pressure maintaining driving member 72, and the base material 001 and the auxiliary material 002 in the accommodation groove 211 are pressed tightly to complete the debubbling at the adhesion position.

[0155] f. secondary pre-folding of the auxiliary material 002:

[0156] As shown in the figure, Figure 20 During this process, the secondary pre-folding assembly 8 works in cooperation with the debubbling assembly 7. The multiple pressing blocks 71 are embedded in the accommodation groove 211, and the secondary pre-folding prongs 81 move upward from the pressing blocks 71 and the sidewall of the carrier 21 below the auxiliary material 002 to fold the auxiliary material 002 upward, obtaining the molded material as shown in the figure. Figure 2

It can be understood that, as long as the production purpose can be met, the base material 001 and the auxiliary material 002 can both be long strip materials, or the base material 001 is a short strip material and the auxiliary material 002 is a long strip material.
