Description

Technical Field

[0001] This utility model belongs to the field of airbag folding technology, and in particular relates to a fully automatic side airbag folding machine. Background Technology

[0002] Typically, various types of airbags are installed in vehicles to protect occupants from collisions. In such airbags, side airbags deploy between the vehicle's doors and the occupants, thereby protecting them by essentially preventing direct impact with the doors and the door glass leading into the vehicle during a side collision.

[0003] Currently, side airbag folding processing is mainly divided into two modes: manual folding and semi-automatic equipment-assisted folding. Manual folding is greatly affected by subjective factors such as worker skill, operating force, concentration, and fatigue. It is difficult to uniformly control the folding angle, number of rolls, and forming size, resulting in extremely poor product consistency. Problems such as folding misalignment, loose edges and corners, and uneven folds are very likely to occur. Some substandard products may directly cause abnormal airbag deployment after being installed in vehicles, creating serious safety hazards.

[0004] To alleviate the drawbacks of manual folding, some side airbag folding auxiliary equipment has gradually appeared on the market. Most existing equipment only has horizontal and vertical folding functions, which is not suitable for folding irregularly shaped airbags. At the same time, the folding and rolling processes require separate manual intervention and cannot achieve continuous fully automatic processing, resulting in limited automation. In addition, the rolling mechanism of existing equipment can not achieve flexible clamping and precise rotational rolling, and the rolling angle and number of turns are difficult to control precisely. The size deviation of the formed airbag is large, which cannot adapt to the process requirements of different specifications of side airbags. Utility Model Content

[0005] In view of this, the present invention aims to provide a fully automatic side airbag folding machine, which solves the problems of low efficiency, poor precision, and insufficient consistency of manual folding, as well as the problems of low automation, poor linkage, and unstable forming of existing equipment, so as to realize fully automatic, high precision, and standardized folding of side airbags, thereby improving production efficiency and product quality.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] like Figures 1 to 3 , Figure 6As shown, a fully automatic side airbag folding machine includes a frame 10, a fixing plate 11, a protective plate 12, a positioning fixture 13, a folding mechanism 14, an upper vertical insertion mechanism 15, a horizontal flipping folding mechanism 16, an oblique flipping folding mechanism 17, and a lower vertical insertion mechanism 18. The fixing plate 11 is installed in the middle of the frame 10, the protective plate 12 is disposed on the front side of the frame 10, two positioning fixtures 13 are disposed on the front and rear sides of the top surface of the fixing plate 11, the folding mechanism 14 and the upper vertical insertion mechanism 15 are disposed on both sides of the positioning fixture 13, and the upper vertical insertion mechanism 18... The bottom surface of the cutting mechanism 15 is higher than the top surface of the folding mechanism 14. The horizontal flipping folding mechanism 16 is installed on one side of the positioning fixture 13 located at the rear and is set close to the folding mechanism 14. The horizontal flipping folding mechanism 16 is set close to the back of the frame 10. The oblique flipping folding mechanism 17 is set between the horizontal flipping folding mechanism 16 and the folding mechanism 14. The lower vertical cutting mechanism 18 is set on the fixed plate 11. The lower vertical cutting mechanism 18 is set between the two positioning fixtures 13. The top surface of the lower vertical cutting mechanism 18 is lower than the bottom surface of the positioning fixture 13.

[0042] The oblique flipping and folding mechanism 17 includes an oblique flipping seat 171, an oblique slide rail 172, an oblique slider 173, an oblique flipping motor 174, and oblique flipping plates 175. The oblique flipping seat 171 is mounted on the top surface of the fixed plate 11. The oblique slide rail 172 is disposed on the top surface of the oblique flipping seat 171. The oblique slider 173 is disposed on the oblique slide rail 172 and moves along the length direction of the oblique slide rail 172. The oblique flipping motor 174 is disposed at one end of the oblique slider 173. The two oblique flipping plates 175 are symmetrically disposed vertically at the output end of the oblique flipping motor 174.

[0043] The folding mechanism 14 includes a folding base 141, longitudinal folding slide rails 142, longitudinal folding sliders 143, transverse folding slide rails 144, transverse folding sliders 145, a folding cylinder 146, a folding motor 147, and a folding plate 148. The folding base 141 is fixed to the top surface of the fixed plate 11. Two longitudinal folding slide rails 142 are installed parallel to each other on the folding base 141, and both longitudinal folding slide rails 142 are perpendicular to the protective plate 12. The longitudinal folding sliders 143 are disposed on the two longitudinal folding slide rails 142 and move along the length direction of the two longitudinal folding slide rails 142. Two transverse folding slide rails 144 are installed parallel to each other on the longitudinal folding slide rails 141. On the top surface of the folding slider 143, two transverse folding slide rails 144 are arranged perpendicularly to two longitudinal folding slide rails 142. The transverse folding slider 145 is arranged on the two transverse folding slide rails 144 and moves along the length of the two transverse folding slide rails 144. The folding cylinder 146 is installed on the top surface of the transverse folding slider 145. The output end of the folding cylinder 146 is connected to one end of the transverse folding slider 145 and pushes the transverse folding slider 145 to move along the transverse folding slide rails 144. The folding motor 147 is arranged at the other end of the transverse folding slider 145. Two folding plates 148 are arranged symmetrically on the output end of the folding motor 147.

[0044] During operation, two positioning fixtures 13 clamp and position the side airbag from the front and rear sides respectively, and place one side of the side airbag into the folding end of the oblique flipping and folding mechanism 17. After the side airbag is installed, the oblique flipping and folding mechanism 17 is activated, and the oblique flipping and folding mechanism 17 folds the side airbag at a 45° angle to the protective plate 12. The folding end of the horizontal flipping and folding mechanism 16 extends out and is located on the upper and lower sides of the output end of the oblique flipping and folding mechanism 17. The folding end of the oblique flipping and folding mechanism 17 retracts, and the horizontal flipping and folding mechanism 16 folds the side airbag again in a direction perpendicular to the protective plate 12, so that the side airbag is folded into a rectangular structure. The folding cylinder 146 is activated, pushing the horizontal folding slider 145 to move along the horizontal folding slide rail 144, driving the two folding plates 148 to move to the middle of the side airbag which is folded into a rectangular structure. The vertical folding slider... 143 moves along the longitudinal folding slide rail 142, so that the two folding plates 148 are located on the upper and lower sides of the middle of the side airbag. The folding end of the horizontal flipping folding mechanism 16 retracts and resets. The upper vertical inserting knife mechanism 15 and the lower vertical inserting knife mechanism 18 work together to assist in clamping the end of the airbag near the protective plate 12 on the folded rectangular structure. The side airbag is pulled out from the positioning fixture 13 away from the end of the protective plate 12. The folding motor 147 starts and drives the two folding plates 148 to rotate synchronously, folding the rectangular side airbag according to the preset angle and number of turns to complete the initial folding and shaping. The folding motor 147 stops working, the horizontal flipping folding mechanism 16 and the oblique flipping folding mechanism 17 reset, and the folded side airbag is removed. During the folding process, the longitudinal folding slider 143 slides synchronously along the longitudinal folding slide rail 142.

[0045] This application enables the folding of side airbags into a rectangular structure, making it suitable for folding side airbags of irregular shapes.

[0046] Two folding plates 148 can be respectively set on clamping sliders. The two clamping sliders move along the clamping slide rail, which is fixed on the clamping seat. The clamping seat is installed at the output end of the folding motor 147. The two clamping sliders are set at both ends of the bidirectional threaded rod. The bidirectional threaded rod is connected to the output end of the rotary motor. The rotary motor drives the bidirectional threaded rod to rotate, which can realize the clamping and separation action of the two folding plates 148.

[0047] When the oblique flipping and folding mechanism 17 is working, the oblique slider 173 extends along the length of the oblique slide rail 172, so that the two oblique flipping plates 175 are at a 45° angle to the protective plate 12 and are located on the upper and lower sides of the side airbag. The oblique flipping motor 174 is started, driving the two oblique flipping plates 175, which are symmetrically arranged at the top and bottom, to perform a 180° flipping action simultaneously. After the flipping is completed, the horizontal flipping and folding mechanism 16 is working, clamping the side airbag in a direction perpendicular to the protective plate 12. At the same time, the oblique slider 173 drives the two oblique flipping plates 175 to retract, and the side airbag after being flipped at 45° is clamped only by the horizontal flipping and folding mechanism 16.

[0048] The clamping structure of the two inclined flipping plates 175 can be the same as the clamping structure of the two folding plates 148.

[0049] One side of the longitudinal folding slider 143 is threadedly connected to the lead screw via a lead screw seat. The lead screw is set parallel to the longitudinal folding slide rail 142. One end of the lead screw is connected to the output end of the drive motor. When the drive motor works, it drives the longitudinal folding slider 143 to move along the length direction of the longitudinal folding slide rail 142.

[0050] like Figure 1 , Figure 5As shown, the horizontal flipping and folding mechanism 16 includes a horizontal flipping base 161, a transverse horizontal flipping slide rail 162, a transverse horizontal flipping slider 163, a longitudinal horizontal flipping slide rail 164, a longitudinal horizontal flipping slider 165, a horizontal flipping motor 166, and a horizontal flipping plate 167. The horizontal flipping base 161 is fixed to the top surface of the fixed plate 11. The two transverse horizontal flipping slide rails 162 are installed parallel to each other on the horizontal flipping base 161. Both transverse horizontal flipping slide rails 162 are perpendicular to the protective plate 12. The transverse horizontal flipping slider 163 is disposed on the two transverse horizontal flipping slide rails 162 and extends along the length of the two transverse horizontal flipping slide rails 162. The two longitudinal horizontal flip slide rails 164 are installed parallel to each other on the top surface of the transverse horizontal flip slider 163. The two longitudinal horizontal flip slide rails 164 are set perpendicular to the two transverse horizontal flip slide rails 162. The longitudinal horizontal flip slider 165 is set on the two longitudinal horizontal flip slide rails 164 and moves along the length direction of the two longitudinal horizontal flip slide rails 164. The horizontal flip motor 166 is set at one end of the longitudinal horizontal flip slider 165. The two horizontal flip plates 167 are symmetrically arranged vertically at the output end of the horizontal flip motor 166. The vertical distance between the two horizontal flip plates 167 is greater than the vertical distance between the two folding plates 148.

[0051] After the two inclined flipping plates 175 simultaneously flip 180°, the longitudinal horizontal flipping slider 165 drives the two horizontal flipping plates 167 to extend, so that the horizontal flipping plates 167 are above the two inclined flipping plates 175. The inclined slider 173 drives the two inclined flipping plates 175 to reset. The two horizontal flipping plates 167 are flipped 180° under the drive of the horizontal flipping motor 166, folding the side airbag into a rectangular structure. At this time, the folding cylinder 146 drives the two folding plates 148 to move to the middle of the side airbag and to the upper and lower sides of the two horizontal flipping plates 167. The longitudinal horizontal flipping slider 165 drives the two horizontal flipping plates 167 to reset, and the folding cylinder 146 drives the two folding plates 148 to complete the folding motion.

[0052] The driving structure of the longitudinal horizontal flip slider 165 and the transverse horizontal flip slider 163 is the same as the driving structure of the longitudinal folding slider 143.

[0053] The clamping structure of the two horizontal flip plates 167 can be the same as the clamping structure of the two folding plates 148.

[0054] like Figures 1 to 2As shown, the positioning fixture 13 includes a positioning seat 131, an upper positioning plate 132, and a lower positioning plate 133. The positioning seat 131 is fixed on the top surface of the fixed plate 11. The upper positioning plate 132 and the lower positioning plate 133 are both installed on the side of the positioning seat 131 near the lower vertical inserting mechanism 18. The side of the positioning seat 131 is recessed inward to form a guide groove. The guide groove is set in the vertical direction. The bottom end of the guide groove extends to the top surface of the lower positioning plate 133. One end of the upper positioning plate 132 extends into the guide groove and can move along the length direction of the guide groove. The top surface of the lower vertical inserting mechanism 18 is lower than the bottom surface of the lower positioning plate 133.

[0055] The front and rear ends of the side airbag are fixed by clamping the upper positioning plate 132 and the lower positioning plate 133 respectively. The lower positioning plate 133 is fixed on the positioning seat 131. The upper positioning plate 132 can be connected to the output end of the cylinder. The cylinder drives the upper positioning plate 132 to move closer to or away from the lower positioning plate 133 in the vertical direction to complete the clamping and releasing of the side airbag.

[0056] like Figure 1 As shown, it also includes a mounting platform 19 and a support leg 20. The support leg 20 is connected to the bottom corner of the mounting platform 19 and is mounted on the fixed plate 11. The upper vertical inserting knife mechanism 15 is set on the top surface of the mounting platform 19.

[0057] By installing the platform 19 and the support legs 20, the upper vertical inserting mechanism 15 is positioned above the positioning seat 131, ensuring the smooth operation of the upper vertical inserting mechanism 15.

[0058] like Figure 1 , Figure 4 As shown, the upper vertical inserting knife mechanism 15 includes an upper vertical inserting knife seat 151, an upper vertical slide rail 152, an upper vertical slide plate 153, an upper vertical cylinder 154, and an upper vertical inserting knife 155. The upper vertical inserting knife seat 151 is disposed on the top surface of the mounting platform 19. Two upper vertical slide rails 152 are mounted on the sides of the upper vertical inserting knife seat 151. The upper vertical slide plate 153 is disposed on the two upper vertical slide rails 152 by a slider. The slider drives the upper vertical slide plate 153 to move along the length direction of the upper vertical slide rails 152. Two upper vertical cylinders 154 are disposed on the outer surface of the upper vertical slide plate 153. Two upper vertical inserting knives 155 are respectively connected to the output end of the corresponding upper vertical cylinder 154. Both upper vertical inserting knives 155 are disposed parallel to the protective plate 12 and facing the fixed plate 11.

[0059] When the side airbag is folded into a rectangular structure, the output end of the lower vertical insert mechanism 18 operates and contacts the bottom surface of the rectangular side airbag. At this time, the upper vertical slide plate 153 slides along the upper vertical slide rail 152 under the drive of the electric telescopic rod, and drives the two upper vertical cylinders 154 to move above the side airbag. The two upper vertical cylinders 154 operate, respectively driving the corresponding upper vertical inserts 155 to move downward. The two upper vertical inserts 155 are located on both sides of the output end of the lower vertical insert mechanism 18, and pull the side airbag out from between the upper positioning plate 132 and the lower positioning plate 133 on the front and rear sides. At this time, the two folding plates 148 are located on the upper and lower sides of the middle of the side airbag. The folding motor 147 starts, driving the two folding plates 148 to rotate synchronously in the direction of the upper vertical insert 155 to complete the folding work.

[0060] like Figure 1 , Figure 7 As shown, the lower vertical inserting knife mechanism 18 includes a lower vertical inserting knife seat 181, a lower vertical cylinder 182, and a lower vertical inserting knife 183. The lower vertical inserting knife seat 181 is mounted on the frame 10. The lower vertical cylinder 182 is located on one side of the lower vertical inserting knife seat 181. The lower vertical inserting knife 183 is mounted on the output end of the lower vertical cylinder 182. The lower vertical inserting knife 183 is located above the fixed plate 11 and between the two upper vertical inserting knives 155.

[0061] Driven by the lower vertical insert 183, the lower vertical insert 183 extends upward and cooperates with the two upper vertical inserts 155 to pull the side airbag out from between the upper positioning plate 132 and the lower positioning plate 133 on the front and rear sides, in preparation for the folding operation.

[0062] This application also includes a vision camera 21, which is mounted on the top surface of the frame 10 and positioned above the two positioning seats 131. The vision camera 21 can identify the size of the airbags clamped by the upper positioning plate 132 and the lower positioning plate 133 on the front and rear sides, and transmit the identified data to the controller. If the size of the side airbag to be folded is preset in the controller, the controller will drive the oblique flipping motor 174, the drive motor, the horizontal flipping motor 166, the folding cylinder 146, the lower vertical cylinder 182, the upper vertical cylinder 154, and the folding motor 147 to work respectively.

[0063] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
