[0050] When the sensor (not shown in the figure) detects that the first profiling die 221 is in contact with the automobile armrest framework, the pressing driving unit 224 drives the three pressing blocks 223 to extend outward, so as to press the automobile armrest framework, thereby fixing the automobile armrest framework on the first profiling die 221.

[0051] The moving device 210 is used for moving the automobile armrest framework. The moving device 210 is a six-axis mechanical arm 211, which moves under the control of the spraying glue control device 240.

[0052] The spraying glue device 231 is used for spraying polyurethane glue on the automobile armrest framework. The spraying glue device 231 comprises a glue spraying head 231 and a glue coating head 232. The glue spraying head 231 is used for spraying glue to the first surface of the automobile armrest framework, and the glue coating head 232 is used for coating glue to the second surface of the automobile armrest framework.

[0053] The glue spraying head 231 is controlled by the spraying glue control device 240 to open and close the spraying. The glue coating head 232 is controlled by the spraying glue control device 240 to open and close the coating.

[0054] The glue spraying head 231 is a fan-shaped head for spraying fibrous glue, and the glue coating head 232 has a large diameter for coating the edge of the glue strip.

[0055] The glue spraying control device 240 controls the movement device 210 to move above the automobile armrest framework, controls the framework fixing device 220 to grab and fix the automobile armrest framework, controls the movement device 210 to move the automobile armrest framework to the glue spraying head 231, controls the glue spraying head 231 to spray glue, so as to spray polyurethane glue on the entire first surface of the automobile armrest framework, and then controls the movement device 210 to move the automobile armrest framework to the glue coating head 232, controls the glue coating head 232 to coat glue, so as to spray polyurethane glue on the entire edge of the second surface of the automobile armrest framework.

[0056] In this embodiment, the automatic glue spraying method of the automobile armrest framework glue spraying equipment 200 specifically includes the following steps:

[0057] Step I: grabbing and fixing the automobile armrest framework.

[0058] Under the control of the glue spraying control device 240, the mechanical arm 211 moves above the automobile armrest framework, and the plurality of pressing mechanisms 222 extend outward according to the detection signal of the sensor, so as to fix the automobile armrest framework on the first profiling die 221.

[0059] Step II: moving the automobile armrest framework to the glue spraying position of the glue spraying head 231.

[0060] Then the mechanical arm 211 moves the automobile armrest framework below the glue spraying head 231, and at this time the glue spraying head 231 faces the first surface of the automobile armrest framework.

[0061] Step III: spraying polyurethane glue on the entire first surface of the automobile armrest framework.

[0062] The glue spraying head 231 sprays glue on the first surface of the automobile armrest framework.

[0063] During the glue spraying process of the glue spraying head 231, the glue spraying control device 240 controls the mechanical arm 211 to move the automobile armrest framework along the first predetermined track along the glue spraying head 231, until the polyurethane glue is sprayed on the entire first surface of the automobile armrest framework.

[0064] The first predetermined track is that the automobile armrest framework moves in a "one" shape along the direction perpendicular to the glue spraying head 231, so that the glue spraying head 231 relatively moves from one side of the automobile armrest framework to the other side, so that the polyurethane glue is sprayed on the entire first surface of the automobile armrest framework.

[0065] Step IV: moving the automobile armrest framework to the glue coating position of the glue coating head 232.

[0066] Subsequently, the robot arm 211 moves the automobile armrest framework to below the glue applying head 232, at this time, the glue applying head 232 faces the second surface of the automobile armrest framework.

[0067] Step V, polyurethane glue is applied to the edge of the second surface of the automobile armrest framework.

[0068] The glue applying head 232 applies glue to the second surface of the automobile armrest framework.

[0069] During the glue applying process of the glue applying head 232, the glue spraying control device 240 controls the robot arm 211 to move the automobile armrest framework along the second predetermined trajectory along the glue applying head 232, until the polyurethane glue is sprayed to the edge of the second surface of the automobile armrest framework.

[0070] The second predetermined trajectory is that the automobile armrest framework moves in an elliptical shape along a direction perpendicular to the glue applying head 232, so that the glue applying head 232 relatively moves along the edge of the automobile armrest framework for one round, so that the polyurethane glue is sprayed to the edge of the second surface of the automobile armrest framework for one round.

[0071] Figure 7 is a front view of the thread wrapping device in the embodiment of the present application.

[0072] As shown in Figure 7 , the thread wrapping device 300 is used for thread wrapping and edge wrapping of the automobile armrest framework after glue spraying, to obtain a finished product.

The sixth profiling die 332 is the same as the shape of the first surface of the automobile armrest framework, and is used for placing the skin and thread wrapping the skin by manual operation according to the shape of the sixth profiling die 332. The vacuum adsorption unit 333 is arranged in the sixth profiling die 332, and is used for adsorbing the skin on the sixth profiling die 332. Specifically, when the skin is adsorbed on the sixth profiling die 332, the surface of the skin used for laminating with the automobile armrest framework is located below and adheres to the sixth profiling die 332.

[0075] Figure 8 is a rear view of the laminating device in the embodiment of the present application. Figure 9 is a rear view of the laminating device in the embodiment of the present application. Figure 10is a structural schematic diagram of the lower mold mechanism in the embodiment of the present application. Figure 11 is a structural schematic diagram of the upper mold mechanism in the embodiment of the present application.

[0076] As shown in Figures 8-11 The covering device 310 is used for covering the skin to the glue-sprayed automobile armrest framework to obtain the skin-covered automobile armrest framework, and includes the lower mold mechanism 319, the upper mold mechanism 311, the bearing mechanism 322, the heating mechanism 327 and the turnover unit 316.

[0077] The lower mold mechanism 319 includes the fifth profiling die 320 and the vacuum positioning unit 321, the shape of the fifth profiling die 320 is matched with the shape of the first surface of the automobile armrest framework, and the vacuum positioning unit 321 is arranged in the interior of the fifth profiling die 320 and used for adsorbing the skin in the fifth profiling die 320.

[0078] Under the control of the thread wrapping control device 350, the thread turnover driving part 336 drives the thread turnover part 335 to turn over, so that the sixth profiling die 332 is pressed on the fifth profiling die 320 and the skin is located between the sixth profiling die 332 and the fifth profiling die 320, then the vacuum adsorption unit 333 stops adsorbing the skin, the positioning by the vacuum positioning unit 321 starts to adsorb the skin, and thus the skin is fixed on the fifth profiling die 320. Specifically, when the skin is adsorbed on the fifth profiling die 320, the surface thereof for covering the automobile armrest framework is located upward.

[0079] The bearing mechanism 322 includes the bearing unit 323 and the bearing driving unit 324, the bearing unit 323 is used for placing the finished product and the glue-sprayed automobile armrest framework, and the bearing unit 323 can move in the horizontal direction under the driving of the bearing driving unit 324. It has a taking and placing part station and a thread wrapping station in the horizontal direction. When it is in the taking and placing part station, it is located close to the mechanical arm 211, facilitating the mechanical arm 211 to place the box and grab the automobile armrest framework and the finished product; when it is in the thread wrapping station, it is located in the same vertical direction with the upper mold mechanism 311, facilitating the cooperation of the seventh profiling die 314 and the seventh clamping unit 315 to clamp and grab the automobile armrest framework.

[0080] The bearing unit 323 includes the second profiling die 325 and the third profiling die 326, the shape of the second profiling die 325 is matched with the shape of the first surface of the automobile armrest framework, the second profiling die 325 is used for the glue-sprayed automobile armrest framework, the third profiling die 326 is used for placing the finished product, and the second profiling die 325 is located close to the thread wrapping device 330 on the side of the third profiling die 326.

[0081] The upper die mechanism 311 is used for fixing the sprayed automobile handrail framework, and comprises a seventh profiling die body 314, a seventh clamping unit 315, a mounting frame 312 and an upper die driving unit 313.

[0082] The seventh profiling die body 314 is reversibly arranged on the mounting frame 312 through a turnover unit 316. The shape of the seventh profiling die body 314 is matched with the shape of the second surface of the automobile handrail framework, and the seventh clamping unit 315 is used for clamping the sprayed automobile handrail framework.

[0083] The shape of the seventh profiling die body 314 is the same as that of the first profiling die body 221, and is matched with the shape of the central recessed position of the second surface of the automobile handrail framework. The seventh profiling die body 314 is embedded into the inside of the central recessed position of the second surface of the automobile handrail framework, and clamps the sprayed automobile handrail framework through the seventh clamping unit 315. At this time, the first surface of the automobile handrail framework is exposed outside as a whole, faces the lower die mechanism 319, and the glue coating part of the second surface is exposed outside, which is convenient for the subsequent heating mechanism 327 to heat and melt the glue. The automobile handrail framework can be grabbed away from the second profiling die body 325 through the seventh profiling die body 314 and the seventh clamping unit 315.

[0084] The heating mechanism 327 is arranged on the mounting frame 312, and is used for heating the sprayed automobile handrail framework to melt the glue on the automobile handrail framework. The heating mechanism 327 comprises a first heating unit 328 and a second heating unit 329, and the first heating unit 328 and the second heating unit 329 are both long strip-shaped lamp tubes. The first heating unit 328 is arranged on the mounting frame 312, and the second heating unit 329 is arranged on the seventh profiling die body 314.

[0085] The turnover unit 316 comprises a turnover part 317 and a turnover driving part 318. The turnover part 317 is arranged on the mounting frame 312, and the seventh profiling die body 314 is arranged on the turnover part 317.

[0086] The turnover part 317 can be turned over by 180 degrees under the driving of the turnover driving part 318, so that the first surface of the sprayed automobile handrail framework faces upward, and the first heating unit 328 is arranged on the mounting frame 312 and is above the first surface of the sprayed automobile handrail framework, so as to completely heat the first surface of the sprayed automobile handrail framework.

[0087] The adhesive portion of the second side of the car armrest frame is exposed on the outside of the seventh contour mold 314. Therefore, the second heating unit 329 faces the adhesive portion of the second side of the car armrest frame and is located at the bottom of the seventh contour mold 314. This allows it to heat the second side of the car armrest frame after the adhesive has been sprayed. The positions of the second heating unit 329 and the seventh contour mold 314 are relatively fixed. During heating, it is not affected by the flipping of the flipping part 317 or the movement of the mounting bracket 312. Therefore, the second heating unit 329 can continue to heat until the skin is covered.

[0088] Driven by the flipping drive unit 318, the flipping unit 317 can also be flipped by -180 degrees, so that the first side of the car armrest frame after the glue is sprayed is facing down and facing the fifth contour mold 320, which facilitates the subsequent lowering of the mounting bracket 312 to place the car armrest frame in the seventh contour mold 314 into the fifth contour mold 320 for edge wrapping.

[0089] Subsequently, under the drive of the upper mold drive unit 313, the mounting bracket 312 can move vertically to press the glued car armrest frame into the interior of the fifth contour mold 320, thereby covering the skin placed inside the fifth contour mold 320 by the alignment device 330 onto the glued car armrest frame.

[0090] Figure 12 This is a schematic diagram of the edge-binding device in an embodiment of the present invention.

[0091] like Figure 12 As shown, the edge-wrapping device 340 is positioned near the overlay device 310 and is used to wrap the edges of the car armrest frame after the skin is overlaid, to obtain the finished product.

[0092] The alignment and edge-wrapping control device 350 is used to control the alignment mechanism 331 to align and position the skin under the control of the control device 400, then flip the skin and place it into the laminating device 310, then control the laminating device 310 to laminate the skin onto the car armrest frame after spraying glue, and finally control the edge-wrapping device 340 to wrap the edge of the car armrest frame after the skin is laminated.

[0093] Figure 13 This is a control diagram of the control device in an embodiment of the present invention.

[0095] Under the control of the control device 350, the turnover driving part 318 drives the turnover part 317 to turn over, so that the seventh profiling die 314 faces the sprayed automobile armrest framework, the upper die driving unit 313 drives the mounting frame 312 to move downward until the sprayed automobile armrest framework is embedded in the seventh profiling die 314, and the seventh clamping unit 315 clamps the sprayed automobile armrest framework, and then the upper die driving unit 313 drives the mounting frame 312 to move upward.

[0096] The turnover driving part 318 drives the turnover part 317 to turn over by 180 degrees, so that the seventh profiling die 314 faces the first heating unit 328, the first heating unit 328 heats the first surface of the sprayed automobile armrest framework, at the same time, the second heating unit 329 heats the second surface of the sprayed automobile armrest framework, after the heating of the first heating unit 328 is completed, the turnover driving part 318 drives the turnover part 317 to turn over by-180 degrees, so that the seventh profiling die 314 faces the fifth profiling die 320, and then the upper die driving unit 313 drives the mounting frame 312 to move downward until the automobile armrest framework is embedded in the fifth profiling die 320, at this time, the second heating unit 329 stops heating, and the seventh clamping unit 315 releases the automobile armrest framework.

[0097] The application further discloses a car armrest covering and edge bonding alignment integrated method, which comprises the following steps.

[0098] S1, the conveying device 100 conveys the automobile armrest framework.

[0099] Under the control of the control device 400, the conveying control device 130 controls the automobile armrest framework conveying driving mechanism 113 to drive the automobile armrest framework conveying mechanism 111 to convey the automobile armrest framework in the fourth profiling die 112.

[0100] S2, the automobile armrest framework spraying glue device 200 sprays glue and applies glue to the automobile armrest framework, and then places the sprayed automobile armrest framework on the alignment and edge bonding device 300.

[0101] Specifically, in this step, the spraying glue control device 240 controls the moving device 210 to move above the automobile handrail framework, controls the framework fixing device 220 to grab and fix the automobile handrail framework, controls the moving device 210 to move the automobile handrail framework to the position of the spraying glue head 231, controls the spraying glue head 231 to spray glue, so that the polyurethane glue is sprayed on the entire first surface of the automobile handrail framework, and then controls the moving device 210 to move the automobile handrail framework to the position of the glue coating head 232, controls the glue coating head 232 to coat glue, so that the polyurethane glue is sprayed on the entire edge position of the second surface of the automobile handrail framework. Then the automobile handrail framework after spraying glue is placed on the second profiling mold 325 by the mechanical arm 211.

[0102] The process of spraying glue specifically includes the following steps:

[0103] Step I, grabbing and fixing the automobile handrail framework.

[0104] Under the control of the spraying glue control device 240, the mechanical arm 211 moves above the automobile handrail framework, and the plurality of pressing mechanisms 222 extend outward according to the detection signal of the sensor, so as to fix the automobile handrail framework on the first profiling mold 221.

[0105] Step II, moving the automobile handrail framework to the spraying glue position of the spraying glue head 231.

[0106] Then the mechanical arm 211 moves the automobile handrail framework below the spraying glue head 231, at this time the spraying glue head 231 faces the first surface of the automobile handrail framework.

[0107] Step III, spraying polyurethane glue on the entire first surface of the automobile handrail framework.

[0108] The spraying glue head 231 sprays glue on the first surface of the automobile handrail framework.

[0109] During the spraying process of the spraying glue head 231, the spraying glue control device 240 controls the mechanical arm 211 to move the automobile handrail framework along the first predetermined track along the spraying glue head 231, until the polyurethane glue is sprayed on the entire first surface of the automobile handrail framework.

[0110] The first predetermined track is that the automobile handrail framework moves in the direction perpendicular to the spraying glue head 231 in the shape of “one”, so that the spraying glue head 231 relatively moves from one side of the automobile handrail framework to the other side, so that the polyurethane glue is sprayed on the entire first surface of the automobile handrail framework.

[0111] Step IV, moving the automobile handrail framework to the glue coating position of the glue coating head 232.

[0112] Then the mechanical arm 211 moves the automobile handrail framework below the glue coating head 232, at this time the glue coating head 232 faces the second surface of the automobile handrail framework.

[0113] Step V, polyurethane glue is applied to the second edge of the automobile armrest framework.

[0114] The glue head 232 applies glue to the second surface of the automobile armrest framework.

[0115] During the glue application process of the glue head 232, the glue spraying control device 240 controls the mechanical arm 211 to move the automobile armrest framework along the second predetermined trajectory along the glue head 232 until the polyurethane glue is sprayed at the edge of the second surface of the automobile armrest framework.

[0116] The second predetermined trajectory is that the automobile armrest framework moves in an elliptical shape in a direction perpendicular to the glue head 232, so that the glue head 232 relatively moves along the edge of the automobile armrest framework for one round, so that the polyurethane glue is sprayed on the edge of the second surface of the automobile armrest framework.

[0117] S3, the lining and edging device 300 lines the skin, and then covers and edges the automobile armrest framework after glue spraying to obtain a finished product.

[0118] Step S3 specifically includes the following steps:

[0119] Step S3-1, under the control of the lining and edging control device 350, the lining and edging driving part 336 drives the lining and edging turning part 335 to turn, so that the sixth profiling die 332 is pressed on the fifth profiling die 320 and the skin is located between the sixth profiling die 332 and the fifth profiling die 320, then the vacuum suction unit 333 stops suctioning the skin, and the vacuum positioning unit 321 starts to suction the skin, so that the skin is fixed on the fifth profiling die 320. Specifically, when the skin is suctioned on the fifth profiling die 320, the surface for covering the automobile armrest framework is located upward.

[0120] Step S3-2, the lining and edging turning driving part 336 drives the lining and edging turning part 335 to turn, so as to realize resetting.

[0121] Step S3-3, the bearing driving unit 324 drives the bearing unit 323 to move towards the side of the lining and edging device 300 until it moves to the pick-and-place work station, the upper die driving unit 313 drives the mounting frame 312 to move downward until the seventh profiling die 314 contacts the second profiling die 325, at this time the seventh clamping unit 315 clamps the automobile armrest framework after glue spraying and fixes it to the turning part 317.

[0122] Step S3-4, the turnover part 317 is driven by the turnover driving part 318 to turn over 180 degrees, so that the first surface of the sprayed and glued automobile armrest framework faces upward, the first heating unit 328 is arranged on the mounting frame 312, at this time, above the first surface of the sprayed and glued automobile armrest framework, the first surface of the sprayed and glued automobile armrest framework is completely heated. At the same time, the upper die driving unit 313 drives the mounting frame 312 to move upward.

[0123] Step S3-5, the glued part of the second surface of the automobile armrest framework is exposed outside the seventh profiling die 314, so the second heating unit 329 faces the glued part of the second surface of the automobile armrest framework, and is arranged at the bottom of the seventh profiling die 314, so as to heat the second surface of the sprayed and glued automobile armrest framework, and the position of the second heating unit 329 is fixed relative to the seventh profiling die 314, and is not affected by the turning of the turnover part 317 and the movement of the mounting frame 312 during heating, so the second heating unit 329 can continuously heat until the skin is covered.

[0124] Step S3-6, the turnover part 317 is driven by the turnover driving part 318 to turn over-180 degrees, so that the first surface of the sprayed and glued automobile armrest framework faces downward, and faces the fifth profiling die 320, facilitating the subsequent downward movement of the mounting frame 312 to place the automobile armrest framework in the seventh profiling die 314 into the fifth profiling die 320 for edge covering.

[0125] Step S3-7, the mounting frame 312 can move downward along the vertical direction under the driving of the upper die driving unit 313, and press the sprayed and glued automobile armrest framework into the interior of the fifth profiling die 320, so as to cover the skin placed in the fifth profiling die 320 by the aligning device 330 onto the sprayed and glued automobile armrest framework, and perform edge covering by the edge covering device 330 to obtain the finished product.

[0126] Step S3-8, the mounting frame 312 moves upward along the vertical direction under the driving of the upper die driving unit 313, and the bearing mechanism 322 moves back to the aligning and edge covering station along the horizontal direction, the mounting frame 312 moves downward along the vertical direction under the driving of the upper die driving unit 313, and places the finished product on the third profiling die 326, and cooperates with the mechanical arm 211 and the framework fixing device to grasp the finished product to the finished product conveying device 120.

[0127] S4, the conveying equipment 100 conveys the finished product.

[0128] The conveying control device 130 controls the finished product conveying driving mechanism 122 to drive the finished product conveying mechanism 121 to convey the finished product under the control of the control equipment 400.

[0129] Effects of the embodiment

[0130] The automobile armrest framework spraying glue equipment, method and automobile armrest covering and edge bonding alignment integrated system according to the present application, by separating the glue spraying head and the glue coating head, the first surface and the second surface of the automobile armrest framework can be sprayed and coated respectively, and the glue needed for edge bonding can be completely sprayed and distributed on the automobile armrest framework.

[0131] The spraying glue control device controls the movement of the mechanical arm, when spraying glue, the mechanical arm moves in a "I" shape along a direction perpendicular to the glue spraying head, so that the glue spraying head moves from one side to the other side of the automobile armrest framework, and the polyurethane glue can be sprayed on the entire first surface of the automobile armrest framework; when coating glue, the mechanical arm moves in an oval shape along a direction perpendicular to the glue coating head, so that the glue coating head moves along the edge of the automobile armrest framework, and the polyurethane glue is sprayed on the edge of the second surface of the automobile armrest framework.

[0132] The present application can integrally convey, spray glue, cover and align and edge bond the automobile armrest framework, save labor cost, and avoid large errors caused by manual operation. Based on the overall control of the control device and the cooperation of the conveying control device, the spraying glue control device and the alignment and edge bonding control device, the spraying glue, alignment, covering, edge bonding and transportation of finished products can be orderly carried out, and the alignment and skeleton placing of the next product can be manually carried out at the end of the spraying glue step. The processing time of a set of products is 75-80s, which is 25s or more shorter than the existing alignment, glue spraying and covering equipment which need manual placing.

[0133] The present application provides an alignment device, so that the skin after alignment can be directly turned into the fifth profiling die in the lower die mechanism, and the automobile armrest framework in the seventh profiling die can be directly covered with the skin in the fifth profiling die by controlling the up-down movement of the mounting frame in the upper die mechanism, thereby realizing automatic alignment, covering and edge bonding.

[0134] The present application provides an alignment device, so that the skin after alignment can be directly turned into the fifth profiling die in the lower die mechanism, and the automobile armrest framework in the seventh profiling die can be directly covered with the skin in the fifth profiling die by controlling the up-down movement of the mounting frame in the upper die mechanism, thereby realizing automatic alignment, covering and edge bonding.

[0135] The present application is characterized in that the automobile handrail framework after spraying glue can be placed on the second and third profiling mold tires for the next step, and the carrying unit can move to the position close to the mechanical arm under the driving of the carrying driving unit, which facilitates the mechanical arm to place the automobile handrail framework and pick up the finished product.

[0136] The heating unit in the present application includes a first heating unit and a second heating unit, wherein the first heating unit is arranged on the mounting frame, and by combining with the turnover part, the first heating unit can face the first surface of the automobile handrail framework, so as to completely heat the glue sprayed on the automobile handrail framework, and the second heating unit is arranged at the bottom of the seventh profiling mold tire, and the position is fixed relative to the profiling mold tire, so that the heating is not affected by the turnover of the turnover part and the movement of the mounting frame, and can be continuously heated until the mounting frame is lowered and completed. Because the glue coating at the edge of the second surface of the automobile handrail framework is relatively thick, compared with the glue spraying on the first surface, the heating time required is longer, especially in the relatively cold environment in northern China, the hot melt adhesive is prone to rapid cooling, and the subsequent heating and melting is more difficult, and the required time is longer. Therefore, on the one hand, the present application sprays glue on the framework, first sprays glue on the first surface, and then coats glue at the edge of the second surface, shortens the time interval from the completion of coating glue at the edge of the second surface to the heating of the second heating unit, and retains some residual heat when coating glue at the edge of the second surface, so as to shorten the heating time of the second heating unit. On the other hand, the second heating unit starts to heat when the first heating unit starts to heat, and continues to heat after the first heating unit stops heating by using the turnover of the turnover part and the movement of the mounting frame to the position, so as to complete the heating of the glue strip at the edge of the second surface. This way of synchronously completing the longer heating step required by the second surface with other steps can effectively save the processing time.

[0137] The shape of the first profiling mold tire and the shape of the seventh profiling mold tire are both matched with the shape of the second surface central recess position of the automobile handrail framework, when the automobile handrail framework needs to be fixed, the first profiling mold tire and the seventh profiling mold tire are embedded in the inside of the second surface central recess of the automobile handrail framework, and the edge of the second surface of the automobile handrail framework needs to be coated with glue outside the framework fixing device, which is convenient for coating and heating.
