Description

Technical Field

[0001] This utility model relates to the field of sewing equipment, and in particular to a fully automatic gantry sewing machine. Background Technology

[0002] Template sewing is a sewing process that uses automated equipment to cut grooves into an acrylic sheet to the required dimensions, allowing for sewing along the grooved path. It is particularly useful in the automotive interior and luggage industries, where the cut pieces are relatively large. Template sewing significantly improves production efficiency and quality consistency. This modular sewing method simplifies and standardizes complex processes for factories, increasing efficiency, reducing defect rates, improving quality and production time stability, and reducing reliance on highly skilled workers.

[0003] Existing template sewing machines have a fixed sewing machine table, and the template is moved left and right by a clamp to achieve the sewing trajectory. This results in insufficient sewing accuracy. In addition, each time the template is changed, it needs to be replaced manually, which requires stopping the machine to replace it, seriously affecting efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned defects in the prior art and provide a fully automatic gantry sewing machine. Through the cooperation of the lifting and returning mechanism and the template conveying mechanism, the sewing template can be automatically changed, replacing the manual replacement method, effectively improving the efficiency and accuracy of sewing template replacement. At the same time, through the clamping sewing mechanism in conjunction with the sewing machine, automated sewing can be achieved, effectively improving sewing efficiency and product sewing quality.

[0005] To achieve the above objectives, this utility model provides a fully automatic gantry sewing machine, comprising:

[0006] A machine base, on which a working platform, a gantry beam, and a sewing template for carrying materials are provided, the gantry beam being horizontally positioned above the working platform;

[0007] A sewing machine, wherein a first displacement mechanism is provided on the gantry beam, and the first displacement mechanism is connected to the sewing machine;

[0008] A lifting and retracting mechanism is symmetrically arranged on both sides of the work platform. The lifting and retracting mechanism is connected to a support extending into the work platform. The support is placed below the work platform and is used to abut against the two ends of the sewing template for lifting.

[0009] A template conveying mechanism is symmetrically arranged below the work platform. The template conveying mechanism abuts against the end of the sewing template and drives the template to move downwards towards the sewing machine.

[0010] The clamping sewing mechanism is located at the rear of the work platform. The clamping sewing mechanism is used to clamp the sewing template and to cooperate with the sewing machine to sew.

[0011] A second displacement mechanism is provided on the base, which is connected to the lifting and retraction mechanism and the template conveying mechanism to achieve synchronous and opposite-direction movement of the two.

[0012] Furthermore, the second displacement mechanism includes a first fixed base fixed within the machine base, a first motor mounted on the first fixed base, and two sets of first transmission belts, a first driving pulley, and a first driven pulley symmetrically arranged on both sides below the work platform. The two ends of the first transmission belt are arranged in a loop around the first driving pulley and the first driven pulley. The first driving pulley is linked to the first motor via a transmission shaft. The lifting and retraction mechanism and the template conveying mechanism are respectively connected to the upper and lower ends of the first transmission belt and are staggered. Thus, using the same power source, the first motor, in conjunction with the first transmission belt enables the lifting and retraction mechanism and the template conveying mechanism to move synchronously and in opposite directions, achieving precise and synchronous replacement of two sewing templates on the work platform, resulting in a compact and stable structure.

[0013] Furthermore, the template conveying mechanism includes a first slide rail fixed to the machine base, a first movable seat movably disposed on the first slide rail, and a first cylinder fixed to the first movable seat. The first cylinder is connected to a first connecting member, and the first movable seat is provided with a first connecting arm, which is connected to the first transmission belt. The precise lifting and lowering of the first connecting member driven by the first cylinder enables the insertion of the sewing template and assists in moving the sewing template to the bottom of the sewing machine for operation. This method is highly automated, requires no manual assistance, and improves the efficiency of changing sewing templates.

[0014] Furthermore, the first connector is a rod-shaped structure, and a second connector corresponding to the position of the first connector is provided at the bottom rear end of the sewing template. The second connector has a first through-hole for inserting the first connector, and a tapered through-hole is formed at the end of the first connector. By providing the through-hole, the accuracy of inserting the first connector into the second connector is improved, and the second connector can distribute the force of the first connector, making the sewing template more stable when moving.

[0015] Furthermore, the lifting and retraction mechanism includes a second slide rail fixed to the machine base, a second sliding seat slidably disposed on the second slide rail, and a second cylinder fixed to the second sliding seat. A third slide rail is provided on the second sliding seat, and a third sliding seat is movably connected to the third slide rail. The second cylinder is connected to the third sliding seat. One end of the support member is fixed to the end of the third sliding seat. The second sliding seat is provided with a second connecting arm, which is connected to the first transmission belt. Through precise lifting and forward / backward displacement, the support member can lift the sewing template after sewing and bring it back to the feeding area for unloading and loading. The action is precise and highly automated.

[0016] Furthermore, the clamping sewing mechanism includes a second transmission belt, a second transmission motor, and two sets of fourth slide rails symmetrically arranged on the machine base. A fourth sliding seat is movably connected to the fourth slide rail. A through-slot is provided at the rear end of the work platform, extending longitudinally to below the gantry beam. The fourth sliding seat passes through the through-slot and is connected to the clamping beam. Several first clamping components are provided on the clamping beam. The second transmission motor is fixed to the machine base and linked to the second transmission belt via a transmission shaft. A third connecting arm is provided on one side of the fourth sliding seat, and the third connecting arm is connected to the second transmission belt. This allows the sewing template to move back and forth to cooperate with the sewing equipment for sewing along different sewing trajectories, making it highly practical.

[0017] Furthermore, the first clamping assembly includes a first clamping main seat fixed to the working platform and a first clamping cylinder disposed on the first clamping main seat, the first clamping cylinder being connected to a clamping member; a clamping column cooperating with the clamping member is provided on the sewing template, a first groove matching the shape of the clamping column is provided at the front end of the first clamping main seat, the middle part of the clamping member is rotatably disposed on the first clamping main seat via a movable shaft, one end of the clamping member is a barb-shaped clamping part, the clamping part is positioned above the first groove, and the other end of the clamping member away from the clamping part is connected to the first clamping cylinder. The first groove at the front end of the first clamping main seat matches the shape of the clamping column on the sewing template, ensuring accurate alignment during clamping, and the barb-shaped clamping part of the clamping member can firmly engage the clamping column, preventing movement and template loosening due to vibration or pulling during sewing, thus affecting sewing quality.

[0018] Furthermore, it also includes an auxiliary component, which is fixedly connected above the first clamping main seat, positioning the clamping member between the auxiliary component and the first clamping main seat. The auxiliary component has a second groove that matches the first groove. The auxiliary component ensures that the clamping column is constrained both vertically when clamped, preventing displacement due to vibration or tension during sewing and movement, thereby improving sewing quality.

[0019] Furthermore, the first displacement mechanism includes a first X-axis assembly mounted on the gantry beam and a Z-axis assembly connected to the first X-axis assembly. The first X-axis assembly includes a fifth slide rail fixed to the gantry beam, a third motor, and a third transmission belt connected to the third motor. The Z-axis assembly includes a Z-axis support slidably mounted on the fifth slide rail, a sixth slide rail mounted on the Z-axis support, and a fourth motor. The fourth motor is connected to a first sewing support via a transmission screw. The first sewing support is slidably mounted on the sixth slide rail, and the sewing device is fixed to the first sewing support. This allows for rapid and precise movement of the X-axis and Z-axis of the sewing device, meeting the needs of various sewing trajectories and achieving a high degree of automation.

[0020] Furthermore, the sewing equipment also includes a second X-axis assembly. The sewing device comprises an upper sewing head and a lower sewing head. The upper sewing head is fixedly connected to the sewing support. The second X-axis assembly includes a seventh slide rail fixed to the base, a fourth drive belt, and a fifth motor linked to the fourth drive belt. A second sewing support is movably connected to the seventh slide rail. A fourth connecting arm is provided on one side of the second sewing support and is connected to the fourth drive belt. The lower sewing head is fixed to the second sewing support and moves synchronously with the upper sewing head. This dual-head sewing equipment, through the cooperation of the first and second X-axis assemblies, enables the upper and lower sewing heads to operate synchronously, ensuring sewing quality.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] This utility model adopts a gantry beam, and a sewing device and a first displacement mechanism are set on the gantry beam to realize the movement of the XZ axis of the upper sewing head, which can improve the sewing operation with precision and efficiency. At the same time, the upper and lower sewing heads are moved synchronously by the cooperation of the first X-axis component and the second X-axis assembly to ensure the sewing quality.

[0023] This utility model employs a template conveying mechanism to push newly loaded sewing templates to the bottom of the sewing equipment for sewing, and a lifting and retracting mechanism to lift the completed sewing templates and bring them back to the initial position for unloading and reloading. The power for the back-and-forth movement is provided by a second displacement mechanism, which drives the lifting and retracting mechanism and the template conveying mechanism to achieve synchronous and opposite-direction movement of the two, thereby realizing automated sewing template replacement sewing operations.

[0024] Before the sewing equipment starts working, the clamping sewing mechanism clamps the new sewing template and transports it to a suitable working position to await the operation of the sewing equipment. When the sewing operation begins, the clamping sewing mechanism adjusts the position of the sewing template back and forth according to the sewing trajectory to cooperate with the sewing operation of the sewing equipment, thereby realizing automated sewing and improving sewing accuracy.

[0025] In summary, this utility model can automatically replace sewing templates without the need for manual intervention, reducing the error rate of manual operation, improving the level of automation in production, optimizing equipment space utilization, reducing equipment and labor costs, meeting the production needs of enterprises, and possessing strong market competitiveness and adaptability.

The lower sewing head 32 is fixed to the second sewing support 333 and moves synchronously with the upper sewing head 31. The configuration of the fourth transmission belt 332 is the same as that of the third transmission belt 213 and will not be described again.

[0045] like Figure 1 The sewing clamping mechanism 6 is located at the rear of the work platform 11. The sewing clamping mechanism 6 is used to clamp the sewing template 13 and to cooperate with the sewing machine for sewing; for example... Figure 3 As shown, the clamping sewing mechanism 6 includes a second transmission belt 61, a second transmission motor 62, and two sets of fourth slide rails 63 symmetrically arranged on the machine base 1. A fourth sliding seat 64 is movably connected to the fourth slide rail 63. A through slot 113 is provided at the rear end of the work platform 11, which is longitudinally arranged and extends to the bottom of the gantry beam 12. The fourth sliding seat 64 passes through the through slot 113 and is connected to the clamping beam 65. Several first clamping components 66 are provided on the clamping beam 65. The second transmission motor 62 is fixed to the machine base 1 and is linked to the second transmission belt 61 through a transmission shaft. A third connecting arm 641 is provided on one side of the fourth sliding seat 64 and is connected to the second transmission belt 61.

[0046] like Figure 5 and Figure 6As shown, the first clamping assembly 66 includes a first clamping main seat 661 fixed to the work platform 11 and a first clamping cylinder 662 disposed on the first clamping main seat 661. The first clamping cylinder 662 is connected to a clamping member 663. A clamping column 131 that cooperates with the clamping member 663 is provided on the sewing template 13. A first groove 6611 matching the shape of the clamping column 131 is provided at the front end of the first clamping main seat 661. The middle part of the clamping member 663 is rotatably disposed on the first clamping main seat 661 through a movable shaft. One end of the clamping member 663 is a barb-shaped clamping part 6631.

To increase the clamping firmness, this embodiment also includes an auxiliary member 664. The auxiliary member 664 is fixedly connected above the first clamping main seat 661, so that the clamping member 663 is positioned between the auxiliary member 664 and the first clamping main seat 661. A second groove 6641 matching the first groove 6611 is provided on the auxiliary member 664. To increase the clamping accuracy, a clamping sensor 665 can also be provided on the auxiliary member for processing the clamping.

[0047] like Figure 8 As shown, to achieve synchronous and opposite-direction movement of the lifting and retraction mechanism 4 and the template conveying mechanism, a second displacement mechanism 7 is provided on the base 1. The second displacement mechanism 7 is connected to the lifting and retraction mechanism 4 and the template conveying mechanism. Specifically, the second displacement mechanism 7 includes a first fixed base 71 fixed in the base 1, a first motor 72 provided on the first fixed base 71, and two sets of first transmission belts 73, a first driving wheel 74, and a first driven wheel 75 symmetrically arranged on both sides below the working platform 11. The two ends of the first transmission belt 73 are arranged in a loop around the first driving wheel 74 and the first driven wheel 75. The first driving wheel 74 is linked to the first motor 72 through a transmission shaft. The lifting and retraction mechanism 4 and the template conveying mechanism are respectively connected to the upper and lower ends of the first transmission belt 73 and are staggered.

[0048] The lifting and retraction mechanisms 4 are symmetrically arranged on both sides of the working platform 11. Each lifting and retraction mechanism 4 is connected to a support member 41 extending towards the working platform 11, specifically as follows: Figure 8As shown, the lifting and retraction mechanism 4 includes a second slide rail 42 fixed to the base 1, a second sliding seat 43 slidably disposed on the second slide rail 42, and a second cylinder 44 fixed to the second sliding seat 43. A third slide rail 45 is provided on the second sliding seat 43, and a third sliding seat 46 is movably connected to the third slide rail 45. The second cylinder 44 is connected to the third sliding seat 46. One end of the support member 41 is fixed to the end of the third sliding seat 46. The second sliding seat 43 is provided with a second connecting arm 431, which is connected to the first transmission belt 73. In the initial state, the lifting and retraction mechanism 4 is lower than the working platform 11, so that the support member 41 is placed below the sewing template 13 for lifting by abutting against both ends of the sewing template 13.

[0049] The template conveying mechanism 5 is symmetrically arranged below the work platform 11. The template conveying mechanism 5 abuts against the end of the sewing template 13 and drives the sewing template 13 to move downwards towards the sewing equipment 3. Specifically, the template conveying mechanism 5 includes a first slide rail 51 fixed to the machine base 1, a first movable seat 52 movably arranged on the first slide rail 51, and a first cylinder 53 fixed to the first movable seat 52. The first cylinder 53 is connected to a first connecting member 54. The first movable seat 52 is provided with a first connecting arm 521, and the first connecting arm 521 is connected to a first transmission belt 73.

[0050] As a preferred option, such as Figures 7-9 As shown, the first connector 54 in this embodiment is a rod-shaped structure. The bottom rear end of the sewing template 13 is provided with a second connector 132 corresponding to the position of the first connector 54. The second connector 132 is provided with a first through hole 133 for the first connector 54 to pass through. A tapered through part 541 is formed at the end of the first connector 54. The tapered through part 541 can be inserted into the first through hole 133 more accurately. The four sides of the sewing template 13 in this embodiment are formed by splicing together with slots 134. The position of the first through hole 133 is placed in the slot 134. Therefore, after the first connector 54 is inserted, it is placed in the slot 134. The first through hole 133 abuts against the middle position of the first connector 54. When the template conveying mechanism 5 is started, the second connector 132 can share the thrust of the first connector 54, making the overall sewing template 13 move more smoothly.

[0051] Brief description of the working principle of this utility model: During operation, all mechanisms are in their initial positions. Two or more sets of sewing templates 13 can be prepared in advance for feeding. Then, with the help of a robotic arm or manual labor, the sewing templates 13 are lowered and placed on the feeding area 111 of the work platform 11. Then, the equipment is started, the second displacement mechanism 7 is activated, driving the template conveying mechanism forward, so that the first connecting piece 54 is placed below the first through hole 133. The specific positioning can be achieved with the help of a sensor. Then, the first cylinder 53 is activated to lift the first connecting piece 54 and insert it into the first through hole 133 to abut against the inner wall of the slot 134. After completion, the second displacement mechanism 7 rotates in the reverse direction, driving the template conveying mechanism to move towards the work area 112 of the work platform 11. Simultaneously, the first connecting piece 54 pushes the sewing template 13 towards the work area 112 until the sewing template 13 reaches the work area 112. Correspondingly, the lifting and retraction mechanism 4 returns to the feeding area 111. Since the work area 112 is not in the initial state... The sewing template 13 is initially unloaded when the lifting and retraction mechanism 4 returns to the loading area 111 during its first operation. After the sewing template 13 reaches the working area 112, a new sewing template 13 is placed in the loading area 111. Then, the clamping sewing mechanism 6 is activated, and the second drive motor 62 drives the first clamping component 66 to move towards the working area 112, causing the clamping component 663 to move forward and clamp the clamping column 131. Then, the second displacement mechanism 7 drives the template conveying mechanism back to the loading area 111, and the lifting and retraction mechanism 4 returns to the working area 112. Then, the sewing operation begins. The first displacement mechanism 2 is activated to drive the sewing equipment 3 to sew according to the set sewing trajectory. Similarly, the clamping sewing mechanism 6 will also assist the sewing equipment 3 in sewing according to the sewing trajectory. The clamping sewing mechanism 6 mainly provides the function of driving the sewing template 13 to move back and forth, while the first displacement mechanism 2 provides the movement of the X-axis and Z-axis. The two work together to realize the movement of the XYZ axes and meet the needs of different sewing trajectories in sewing.

[0052] After sewing is completed, the template conveying mechanism repeats the above actions to insert a new sewing template 13. Simultaneously, the lifting and retracting mechanism 4 is activated, raising the support 41. The support 41 will press against the left and right ends of the sewing template 13, causing it to rise along with the support 41 until the sewing template 13 that has been sewn is higher than the working area 112. The height of its rise only needs to ensure that it collides with the new sewing template 13. Then, the second displacement mechanism 7 continues to be activated, driving the lifting and retracting mechanism 4 to move towards the loading area 111, and the template conveying mechanism 5 to move towards the working area 112. After reaching the position, it resets, placing the new sewing template 13 in the working area 112. The sewing template 13 that has been sewn is placed in the loading area 111, and the worker can assist in unloading the material. This process is repeated to achieve uninterrupted sewing operations.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
