Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of safety belt assembly manufacturing, in particular to a safety belt assembly manufacturing device. BACKGROUND

[0002] When driving and riding in a car, users need to wear safety belts to protect themselves. When wearing a safety belt, the user needs to pull the safety buckle of the safety belt, and after the safety belt crosses the user's chest and hip, the safety buckle is inserted into the safety lock to complete the wearing of the safety belt.

[0003] When the user does not wear a safety belt, the retractor at the end of the safety belt will pull the safety belt to a taut state and make the safety belt close to the inner wall of the car. Since the safety buckle is inserted in the safety belt in a slidable manner, when the safety belt is in a taut state, the safety buckle will naturally slide down to the bottom end of the safety belt due to gravity. The user will not be able to easily find and pull the safety buckle at the low end of the safety belt, and thus cannot smoothly insert the safety buckle into the safety lock. Therefore, to avoid the safety buckle from sliding down the safety belt surface to a position that the user cannot easily reach due to gravity, a buckle belt is provided on the surface of the safety belt to prevent the safety buckle from sliding down the safety belt surface to the low end of the safety belt.

[0004] In the prior art, the buckle belt is manually sewn onto the surface of the safety belt. However, when manually sewing the buckle belt, it is difficult for the human to control the position of the buckle belt on the surface of the safety belt, resulting in a deviation in the position of the buckle belt on the surface of the safety belt for different safety belts, which in turn causes the safety buckle to be stopped by the buckle belt at different positions on the surface of the safety belt for different safety belts, affecting the uniformity of the height at which the safety buckle is stopped on the surface of the safety belt, and thus affecting the quality of the product.

[0042] Reference Figures 1 to 20 A safety belt assembly manufacturing apparatus according to a preferred embodiment of the present application will be described in detail below, wherein the safety belt assembly manufacturing apparatus comprises a device body 10, a buckle belt 20, a shaping assembly 30 and a sewing assembly 40.

[0043] Specifically, the device body 10 comprises a device body 11 and a belt placing table 12. The belt placing table 12 is arranged on the device body 11, and the belt placing table 12 has a belt placing channel 121 for placing a safety belt 92.

[0044] The shaping assembly 30 is arranged on the device body 11, and the shaping assembly 30 is used to fold two end portions of the buckle belt 20 consistent with the extension direction of the safety belt 92 to form a folded abutting portion 21 at each end of the buckle belt 20, and the shaping assembly 30 is used to arrange the folded buckle belt 20 at a predetermined position on the surface of the safety belt 92.

[0045] The sewing assembly 40 includes a sewing body 41. The sewing body 41 is disposed on the device body 11, and the sewing body 41 has a sewing end 411. The sewing end 411 is directed towards the buckle strap 20 folded on the surface of the safety belt 92 at a predetermined position, and the sewing end 411 is used to sew the buckle strap 20 on the surface of the safety belt 92.

[0046] Preferably, the buckle strap 20 is implemented by, but not limited to, being made of polyester, polypropylene, or nylon.

[0047] Specifically, the shaping assembly 30 includes a strap receiving member 31 and an edge folding and laminating member 32.

[0048] The strap receiving member 31 includes a strap receiving plate 311 and a lifting plate driving member 312. The lifting plate driving member 312 is disposed on the device body 11. The strap receiving plate 311 is movably disposed on the output end of the lifting plate driving member 312. The width of the strap receiving plate 311 in the direction consistent with the extension of the safety belt 92 is smaller than the length of the buckle strap 20 in the extension direction. The strap receiving plate 311 forms a strap placing space 31101 for placing the unfolded buckle strap 20.

[0049] The edge folding and laminating member 32 includes a shaping body 321 and a moving and pushing unit 322. The moving and pushing unit 322 is disposed on the device body 11. The shaping body 321 is disposed on the output end of the moving and pushing unit 322 in a manner that it can move from above the safety belt 92 to above the strap receiving plate 311. The shaping body 321 and the strap receiving plate 311 correspond to each other in the direction perpendicular to the extension direction of the safety belt 92. The shaping body 321 has at least one pair of top strap portions 3211. One pair of the top strap portions 3211 is disposed on both ends of the shaping body 321 in the direction consistent with the extension direction of the safety belt 92, and extends towards the safety belt 92 to form a shaping groove 32101 matched with the strap receiving plate 311. The strap placing space 31101 and the shaping groove 32101 correspond to each other in the direction perpendicular to the extension direction of the safety belt 92. The strap receiving plate 311 is disposed on the output end of the lifting plate driving member 312 in a manner that the part of the strap receiving plate 311 placing the buckle strap 20 in the strap placing space 31101 can be pushed into the shaping groove 32101, and the two end portions of the buckle strap 20 longer than the width of the strap receiving plate 311 are erected away from the shaping body 321 under the pressing of the one pair of the top strap portions 3211.

[0050] As an example, after the buckle belt 20 is placed in the belt placing space 31101, the two ends of the buckle belt 20 which are longer than the width of the belt receiving plate 311 will extend along the surface of the belt receiving plate 311 and hang down. After the shaping body 321 is moved by the moving and pushing unit 322 from above the safety belt 92 to above the belt receiving plate 311 in a manner that the shaping groove 32101 corresponds to the belt placing space 31101 of the belt receiving plate 311, the plate lifting driving member 312 will drive the belt receiving plate 311 and push the two ends of the buckle belt 20 which extend along the surface of the belt receiving plate 311 and hang down into the shaping groove 32101. Under the pressure of the top belt part 3211, the two ends of the buckle belt 20 which extend along the surface of the belt receiving plate 311 and hang down will stand up in a direction away from the shaping body 321.

[0051] Preferably, the edge folding and overlapping member 32 further comprises a pushing edge unit 323. The pushing edge unit 323 comprises at least one pair of pushing edge driving members 3231 and a pushing edge member 3232 corresponding to the pushing edge driving members 3231. The pair of pushing edge driving members 3231 are arranged on the shaping body 321. The pair of pushing edge driving members 3231 are respectively arranged on the two sides of the shaping body 321 in a direction consistent with the extension direction of the safety belt 92. The pair of pushing edge members 3232 are arranged on the output ends of the pushing edge driving members 3231 in a manner that they can move relative to and push the standing up parts of the two ends of the buckle belt 20.

[0052] As can be understood by those skilled in the art, after the two ends of the buckle belt 20 which extend along the surface of the belt receiving plate 311 and hang down stand up in a direction away from the shaping body 321, the pair of pushing edge driving members 3231 drive the pushing edge members 3232. During the process, the pair of pushing edge members 3232 move relative to and push the standing up parts of the two ends of the buckle belt 20 which stand up in a direction away from the plate lifting driving member 312, and the standing up parts of the two ends of the buckle belt 20 are folded and form the overlapping abutting part 21.

[0053] It is worth mentioning that after the two ends of the buckle belt 20 are folded to form the laminated abutting portion 21, the moving and pushing unit 322 drives the shaping main body 321 and moves the buckle belt 20 with the laminated abutting portion 21 in the shaping groove 32101 to a predetermined position on the surface of the safety belt 92. At the same time, during the movement of the buckle belt 20 driven by the shaping main body 321, the buckle belt 20 will be separated from the belt receiving space 31101 of the belt receiving plate 311, and the buckle belt 20 will fall to the surface of the shaping groove 32101 due to gravity, so that the buckle belt 20 after being folded is supported by the pushing edge member 3232 to avoid falling from the shaping groove 32101.

[0054] Preferably, the belt receiving member 31 further comprises at least one clamping member 313 and at least one clamping driving member 314. The clamping member 313 is arranged on the output end of the clamping driving member 314 in a manner that can approach and move away from the belt receiving plate 311. The clamping driving member 314 is arranged on the end of the belt receiving plate 311 away from the shaping main body 321, and the clamping member 313 can move with the belt receiving plate 311.

[0055] It is worth mentioning that when the buckle belt 20 is arranged in the belt receiving space 31101 of the belt receiving plate 311, the clamping member 313 can be driven by the clamping driving member 314 to move towards the belt receiving plate 311, so that the buckle belt 20 in the belt receiving space 31101 is pressed on the surface of the belt receiving plate 311 by the clamping member 313. When the buckle belt 20 in the belt receiving space 31101 is pushed into the shaping groove 32101 under the drive of the lifting plate driving member 312, the buckle belt 20 is prevented from deviating on the surface of the belt receiving plate 311, thereby preventing the two ends of the buckle belt 20 extending away from the belt receiving plate 311 from being pressed by the top belt portion 3211 of the shaping main body 321 and standing away from the shaping main body 321.

[0056] As an example, when the moving and pushing unit 322 drives the shaping main body 321 and moves the buckle belt 20 in the shaping groove 32101 to a predetermined position on the surface of the safety belt 92, a pair of pushing edge driving members 3231 drives the corresponding pushing edge members 3232 away from the buckle belt 20. After the buckle belt 20 loses the support of the pushing edge members 3232, it falls to the predetermined position on the surface of the safety belt 92 due to gravity. After the shaping main body 321 is driven by the moving and pushing unit 322 and removed from above the safety belt 92, the buckle belt 20 can be sewn on the surface of the safety belt 92 by the sewing end 411.

[0057] As preferred, the plate lifting driving member 312 and the clamping driving member 314 are both implemented as a telescopic cylinder.

[0058] The pushing unit 322 and the pushing edge driving member 3231 are both implemented as a telescopic cylinder.

[0059] It is worth mentioning that, since the two ends of the buckle strap 20 which are consistent with the extending direction of the safety belt 92 are folded and formed as the overlapped abutting portion 21, the thickness of the buckle strap 20 on the surface of the safety belt 92 is increased after the buckle strap 20 is sewn on the surface of the safety belt 92, so that the safety buckle 91 is more easily stopped by the overlapped abutting portion 21 of the buckle strap 20 from sliding on the surface of the safety belt 92 in the extending direction of the safety belt 92.

[0060] It is worth mentioning that, since the two ends of the buckle strap 20 which are consistent with the extending direction of the safety belt 92 are folded and formed as the overlapped abutting portion 21, the thickness of the buckle strap 20 on the surface of the safety belt 92 is increased after the buckle strap 20 is sewn on the surface of the safety belt 92, so that the safety buckle 91 is more easily stopped by the overlapped abutting portion 21 of the buckle strap 20 from sliding on the surface of the safety belt 92 in the extending direction of the safety belt 92.

[0061] Meanwhile, since the two ends of the buckle strap 20 which are consistent with the extending direction of the safety belt 92 are folded and formed as the overlapped abutting portion 21, the surface of the buckle strap 20 extending to the overlapped abutting portion 21 is smooth and more beautiful. The fibers of the overlapped abutting portion 21 formed by folding the buckle strap 20 to stop the safety buckle 91 from sliding on the surface of the safety belt 92 in the extending direction of the safety belt 92 are continuous, so that the toughness of the overlapped abutting portion 21 is improved.

[0062] Preferably, the sewing assembly 40 further comprises at least one stabilizing member 42. The stabilizing member 42 is arranged on the sewing body 41. The stabilizing member 42 is used to press the buckle strap 20 folded from the shaping groove 32101 to a predetermined position on the surface of the safety belt 92, so as to avoid the buckle strap 20 from being shaken by the sewing end 411 during the process of sewing the buckle strap 20 on the surface of the safety belt 92, and to avoid the buckle strap 20 from deviating from the predetermined sewing position due to the shaking.

[0063] Meanwhile, the shaping body 321 is removed from above the safety belt 92 by the moving and pushing unit 322, and the pressing and stabilizing member 42 presses the clasp belt 20 on the surface of the safety belt 92 at a predetermined position after being folded from the shaping groove 32101, so that the clasp belt 20 is prevented from deviating from the predetermined position due to adhesion to the inner side of the shaping groove 32101.

[0064] Specifically, the pressing and stabilizing member 42 has at least one anti-skid part 421. The anti-skid part 421 is located on the side of the pressing and stabilizing member 42 facing the clasp belt 20. The anti-skid part 421 of the pressing and stabilizing member 42 is pressed on the surface of the clasp belt 20, so that the clasp belt 20 is prevented from deviating from the predetermined position due to sliding when being pressed on the surface of the safety belt 92.

[0065] Preferably, the sewing assembly 40 further comprises a line cutting member 43. The line cutting member 43 is arranged on the sewing body 41, and is used to cut the sewing line on the surface of the clasp belt 20 after the clasp belt 20 is sewn on the surface of the safety belt 92.

[0066] Specifically, the line cutting member 43 comprises a telescopic member 431 and a line cutting structure 432. The telescopic member 431 is arranged on the sewing body 41. The line cutting structure 432 has a line cutting end 4321 for cutting the sewing line on the surface of the clasp belt 20. The line cutting structure 432 is arranged on the output end of the telescopic member 431 in such a manner that the line cutting end 4321 can extend to and cut the sewing line on the surface of the clasp belt 20.

[0067] It should be noted that since the sewing line for sewing the clasp belt 20 and the safety belt 92 is composed of a plurality of thin single lines, the thin single lines are prone to separate from each other at the cutting position after the sewing line is cut, which affects the appearance.

[0068] Preferably, the line cutting end 4321 can be heated to a predetermined temperature, so that the ends of the plurality of single lines at the cutting position of the sewing line are fused with each other due to high temperature after the sewing line composed of the plurality of single lines is cut by the line cutting end 4321, thereby preventing the plurality of single lines at the cutting position from separating from each other.

[0069] It is to be noted that in the process of placing the buckle belt 20 in the placing space 31101 by hand and allowing the buckle belt 20 to be clamped by the clamping member 313 and the belt supporting plate 311, the two end portions of the buckle belt 20 extending along the surface of the belt supporting plate 311 in the direction away from the belt supporting plate 311 can deviate from the predetermined positions due to the pose deviation caused by the manual placement of the buckle belt 20, and thus the two end portions of the buckle belt 20 extending along the surface of the belt supporting plate 311 in the direction away from the belt supporting plate 311 cannot be pressed by the top belt portion 3211 of the shaping main body 321 and erected in the predetermined manner in the direction away from the shaping main body 321 when the belt supporting plate 311 pushes the buckle belt 20 into the shaping groove 32101.

[0070] In the present embodiment, the manufacturing device of the safety belt assembly further comprises a placing assembly 50. The placing assembly 50 is used for placing the buckle belt 20. The belt supporting member 31 further comprises a belt supporting driving unit 315. The belt supporting driving unit 315 is arranged on the device body 11, and the lifting plate driving member 312 is arranged on the output end of the belt supporting driving unit 315 in such a manner that the belt supporting plate 311 can be extended below the buckle belt 20 placed in the placing assembly 50 and allow the buckle belt 20 to be in the placing space 31101.

[0071] Specifically, the placing assembly 50 comprises a moving unit 51 and a placing member 52. The moving unit 51 is arranged on the device body 11. The placing member 52 has a placing space 5201 for placing the buckle belt 20 and forms a buckle plate insertion groove 5202 for inserting the belt supporting plate 311, and the placing space 5201 and the buckle plate insertion groove 5202 are in communication. The placing member 52 is arranged on the output end of the moving unit 51, so as to be moved to a predetermined position by the driving of the moving unit 51, and in the process of moving the lifting plate driving member 312 by the belt supporting driving unit 315, the belt supporting plate 311 on the output end of the lifting plate driving member 312 is inserted into the buckle plate insertion groove 5202, and thus the part of the buckle belt 20 in the placing space 5201 and at the position in communication between the placing space 5201 and the buckle plate insertion groove 5202 is lifted.

[0072] It is appreciated by those skilled in the art that, during the process that the carrying belt driving unit 315 drives the lifting plate driving member 312 to move, the carrying plate 311 at the output end of the lifting plate driving member 312 will be inserted into the supporting plate insertion slot 5202, and at the same time, the part of the supporting buckle belt 20 at the position where the placing space 5201 and the supporting plate insertion slot 5202 are communicated will be located in the belt placing space 31101. During the process that the clamping member 313 is driven by the clamping driving member 314 to move towards the carrying plate 311, the part of the supporting buckle belt 20 at the position where the placing space 5201 and the supporting plate insertion slot 5202 are communicated will be clamped by the carrying plate 311 and the clamping member 313, so that the supporting buckle belt 20 is arranged in the belt placing space 31101 in a predetermined pose.

[0073] It is worth mentioning that, since the pose of the supporting buckle belt 20 arranged in the placing space 5201 is controllable, the position of the part of the supporting buckle belt 20 at the position where the placing space 5201 and the supporting plate insertion slot 5202 are communicated in the belt placing space 31101 is also controllable when the carrying plate 311 extends into the supporting plate insertion slot 5202.
