[0008] The secondary folding mechanism is installed on the jig and consists of a number of folding plates and a driving structure that cooperate with each other. The driving structure is used to drive the folding plates to move closer to the jig. During the process of moving closer, the folding plates bend the folded leather so that the part of the leather that is higher than the accommodating cavity is folded and fits to the top of the workpiece.

[0009] Furthermore, the jig includes a jig base plate, a floating suction cup and a limit frame, a floating suction cup that can be moved up and down is arranged in the limit frame, and the limit frame and the floating suction cup are both installed on the jig base plate, and a receiving groove is provided between the upper surface of the limit frame and the upper surface of the floating suction cup.

[0010] The fixture structure has the advantages of stable fixation, flexible adjustment, precise positioning, easy maintenance and high applicability through the design of the base plate, floating suction cup and limit frame. It is suitable for positioning and fixing when wrapping workpieces, which helps to improve production efficiency and product quality.

[0011] Furthermore, the folding assembly comprises:

[0012] A base plate, serving as a carrier, is installed on the lifting structure and moves under the drive of the lifting structure;

[0013] The specifications of the folding structure are adapted to the workpiece and are used to press the workpiece into the receiving groove. The folding structure is composed of a plurality of folding blocks movably mounted on the bottom plate.

[0014] The expansion structure is used to adjust the distance between the folding blocks, thereby adjusting the specifications of the folding structure.

[0015] The extended structure can adjust the distance between the folding blocks, thereby adjusting the specifications of the folding structure to adapt it to workpieces of different sizes and shapes, thereby improving the flexibility and applicability of the equipment and meeting diverse production needs.

[0016] This folding component structure, through the design of the base plate, folding structure and extension structure, has the advantages of flexible adjustment, precise pressing, efficient movement, easy maintenance and strong adaptability, which helps to improve the efficiency and quality of the wrapping process.

The side wall of the expansion block abuts against the folding block, and the side wall of the expansion block is inclined outward so that the cross section of the expansion block gradually expands from top to bottom.

[0022] The side wall of the expansion block is inclined outward, so that the cross section of the expansion block gradually expands from top to bottom. This design can effectively push or retract the folding block when driving the expansion block to move, thereby realizing the expansion function of the folding structure.

[0023] Furthermore, the folding plates are provided with four pieces and are all L-shaped. When the folding plates are driven by the driving structure to abut against each other, they form a square frame, and a folding groove with a specification smaller than the accommodating groove is provided in the square frame.

This helps to ensure smooth operation during the lifting process, and also provides a good working environment and operating platform.

[0028] The output shaft head of the lifting drive member passes through the inner side of the support frame and is fixedly connected to the movable plate.

DETAILED DESCRIPTION

[0049] See also Figure 1 As shown, the technical solution adopted in this specific embodiment is: a fully automatic leather wrapping device, which includes: a jig 1, a primary folding mechanism 2, a secondary folding mechanism 3 and a positioning mechanism 4. In specific operation, the positioning mechanism 4 moves the workpiece onto the jig 1, and then the primary folding mechanism 2 presses the workpiece downward so that the leather wraps the side wall of the workpiece, and then the secondary folding mechanism 3 performs a secondary folding on the leather folded after the primary folding, so that the part of the leather higher than the accommodating cavity is folded and attached to the top of the workpiece.

[0050] See also Figure 2 As shown, in a specific embodiment:

[0051] The jig 1 is used to place leather and workpieces that are fitted together; the jig 1 includes a jig base plate 11, a floating suction cup 12 and a limit frame 13. A floating suction cup 12 that can be moved up and down is arranged in the limit frame 13. By adjusting the position of the suction cup, it can adapt to workpieces of different thicknesses, which increases the flexibility and applicability of the jig 1 and reduces the adjustment cost and time when replacing the workpiece. The limit frame 13 and the floating suction cup 12 are both installed on the jig base plate 11. The base plate 211 provides a stable support foundation, making the overall structure of the jig 1 more solid and not easy to move or shake, which is conducive to maintaining the stable position of the workpiece and leather during operation.

The shape of the receiving groove 14 is the same as that of the workpiece, and the specifications are exactly the same as the specifications of the side wall of the workpiece after wrapping the leather.

[0052] The fixture 1 structure has the advantages of stable fixation, flexible adjustment, precise positioning, easy maintenance and high applicability through the design of the base plate 211, the floating suction cup 12 and the limit frame 13.

[0054] The primary folding mechanism 2 includes a folding assembly 21 and a lifting structure 22. The lifting structure 22 is used to drive the folding assembly 21 to move, press the workpiece into the accommodating groove 14 so that the upper surface of the workpiece is flush with the upper surface of the fixture 1 and the leather is folded to wrap the side wall of the workpiece.

[0055] The specific folding assembly 21 includes:

[0056] The bottom plate 211 as a carrier is installed on the lifting structure 22 and moves under the drive of the lifting structure 22.

[0057] The folding structure 212 is used to press the workpiece into the receiving groove 14 , and the folding structure 212 is composed of a plurality of folding blocks 2121 movably mounted on the bottom plate 211 .

[0058] The expansion structure 213 is used to adjust the distance between the folding blocks 2121, thereby adjusting the specifications of the folding structure 212. The expansion structure 213 can adjust the distance between the folding blocks 2121, thereby adjusting the specifications of the folding structure 212, so that it can adapt to workpieces of different sizes and shapes, improve the flexibility and applicability of the equipment, and meet diverse production needs.

[0059] This folding assembly 21 structure, through the design of the base plate 211, the folding structure 212 and the extension structure 213, has the advantages of flexible adjustment, precise pressing, efficient movement, easy maintenance and strong adaptability, which helps to improve the efficiency and quality of the wrapping process.

[0060] More specifically, the expansion structure 213 includes an expansion block 2131 and an expansion drive member 2132 for driving the expansion block 2131 to move. The side wall of the expansion block 2131 abuts against the folding block 2121. This tight connection ensures that the expansion block 2131 maintains a good connection with the folding block 2121 during the movement, thereby achieving precise control of the folding block 2121. The side wall of the expansion block 2131 is tilted outward so that the cross section of the expansion block 2131 gradually expands from top to bottom. This design can effectively push or retract the folding block 2121 when driving the expansion block 2131 to move, thereby achieving the expansion function of the folding structure 212.

[0061] The specific lifting structure 22 includes a lifting drive 221, a support frame 222 and a movable plate 223 installed on the support frame 222. The lifting drive 221 is vertically installed at the top of the support frame 222, and the output shaft head of the lifting drive 221 penetrates the inner side of the support frame 222 and is fixedly connected to the movable plate 223. The support frame 222 provides a stable support platform, and the movable plate 223 is installed on the support frame 222. This helps to ensure the smooth operation of the movable plate 223 during the lifting process, and also provides a good working environment and operating platform. The output shaft head of the lifting drive 221 penetrates the inner side of the support frame 222 and is fixedly connected to the movable plate 223. This rigid connection method ensures a firm connection between the lifting drive 221 and the movable plate 223, avoids deviation or looseness during the lifting process, and ensures the stability and safety of the lifting movement.

[0063] The secondary folding mechanism 3 is installed on the jig 1 and consists of a plurality of folding plates 31 and a driving structure 32 that cooperate with each other. The driving structure 32 is used to drive the folding plates 31 to move closer to the jig 1. During the process of moving closer, the folding plates 31 bend the folded leather so that the part of the leather that is higher than the accommodating cavity is folded and fits to the top of the workpiece. The secondary folding mechanism 3 is relatively simple and easy to operate and maintain. The folding plates 31 are relatively easy to adjust, which is convenient for adjusting processing parameters and maintaining equipment, and is conducive to improving the reliability and stability of the equipment.

[0064] More specifically, there are four folding plates 31 and all of them are L-shaped. When the four folding plates 31 are driven by their respective driving structures 32 to abut against each other, they form a square frame and a folding groove 311 with a smaller specification than the accommodating groove 14 is provided in the square frame.

[0065] See also Fig. 9 As shown, in a specific embodiment:

[0066] The alignment mechanism 4 is used to carry the leather and workpiece that are bonded together to the jig 1. The alignment mechanism 4 realizes automatic carrying and alignment of the leather and workpiece that are bonded together, thereby improving production efficiency and work efficiency. No manual intervention is required, and high-speed and accurate carrying and alignment operations can be achieved.

[0067] More specifically, the alignment mechanism 4 includes:

[0068] A feeding assembly 41, for conveying the leather and the workpiece which are bonded together;

[0069] A detection device 42, used to detect the position of the leather and the workpiece on the feeding assembly 41;

[0070] The adsorption structure 43 is used to adsorb the leather and the workpiece on the feeding component 41; the adsorption structure 43 can firmly adsorb the leather and the workpiece, ensuring the stability and reliability of the workpiece and the leather during the alignment process.

[0071] An angle adjuster 44 is used to drive the adsorption structure 43 to rotate so that the leather and the workpiece are aligned with the fixture 1;

[0072] The displacement component 45 is used to adjust the position of the angle adjuster in the three-dimensional coordinate system.

[0073] The working principle of the utility model is as follows: first, the leather pre-bonded to the bottom of the workpiece is transported by the feeding assembly 41 to the bottom of the detection device 42. The detection device 42 is used to detect the position of the leather and the workpiece on the feeding assembly 41, and then the adsorption structure 43 moves down to adsorb the leather and the workpiece. After the adsorption is completed, the angle adjuster 44 rotates to align the angle of the leather and the workpiece with the receiving groove 14 on the fixture 1. After the alignment is completed, the displacement assembly 45 adjusts the position of the angle adjuster in the three-dimensional coordinate system to transfer the workpiece into the fixture 1.

[0074] After the workpiece and the leather are placed in the jig 1, the lifting structure 22 drives the folding assembly 21 to move downward, pressing the workpiece placed on the jig 1 into the receiving groove 14 so that the upper surface of the workpiece is flush with the upper surface of the jig 1 and the leather is folded to wrap the side wall of the workpiece. In this way, one folding in the wrapping process is completed.

[0075] After the first folding is completed, the first folding mechanism 2 and the second folding mechanism 3 cooperate with each other to fold the part of the leather that is higher than the accommodating cavity to fit the top of the workpiece. The specific driving structure 32 drives the folding plate 31 to move closer to the fixture 1. When the folding plate 31 contacts the leather, the expansion block 2131 retracts to reduce the distance between the folding blocks 2121. The folding blocks 2121 retract into the fixture 1, and the folding plate 31 moves toward the inside of the fixture 1 following the retraction of the expansion block 2131 until the second folding in the wrapping process is completed.

[0076] After the secondary folding is completed, the primary folding mechanism 2 and the secondary folding mechanism 3 are reset, and the floating suction cup 12 rises to eject the wrapped workpiece from the accommodating groove 14 .
