[0002] With economic development, cars have become a daily means of transportation. As people's living standards continue to improve, the requirements for processing auto parts and components, especially automotive trim, are becoming increasingly demanding. The automotive interior system is a crucial component of the vehicle body and primarily includes subsystems such as the instrument panel, sub-instrument panel, door trim, roof, seat, and pillar trim.

[0003] The manufacturing process of automotive interior parts often requires a glue spraying process. The existing technology lacks a transfer device specifically designed to transfer automotive interior parts between a storage device and a glue spraying device. Typically, a worker must manually move each automotive interior part from the storage device to a glue spraying station within the glue spraying device before glue spraying. After glue spraying is complete, the part is returned to the storage device for storage. The next automotive interior part to be glued is then moved from the storage device to the glue spraying device. This transfer process is time-consuming and labor-intensive, with long time intervals. The glue spraying device is temporarily idle while waiting for parts to be loaded and unloaded, wasting significant time and resulting in low processing efficiency. Summary of the Invention

[0040] like Figure 3 As shown, the support mechanism 10 includes a first frame 11. The first frame 11 is rectangular, with its long sides arranged along the vertical direction and its short sides arranged along the first horizontal direction.

[0041] The support mechanism 10 further includes a position driving unit 15, a third guide rail 14, and a third slider 13 adapted to the third guide rail 14. The third guide rail 14 is fixed to the ground along a first horizontal direction. The third slider 13 is disposed at the bottom of the first frame 11 and is slidably connected to the third guide rail 14, so that the first frame 11 can be horizontally movably disposed on the third guide rail 14.

[0042] Figure 4 yes Figure 3 A partial enlarged view of the structure within the middle circle A.

[0043] like Figure 4 As shown, the position drive unit 15 includes a fourth rack 151, a fourth gear 152 and a fourth motor 153.

[0045] like Figure 5As shown, the vertical movement mechanism 20 includes a second frame 21 disposed on the first frame 11 and a vertical drive unit 22 for driving the second frame 21 to move vertically. The second frame 21 includes two side frames 211, a top frame beam 212, and a bottom frame beam 213. The side frames 211 are hexagonal shapes formed by combining a trapezoid and a rectangle. The two side frames 211 are arranged relative to each other at a certain distance. The top frame beam 212 is disposed at the top of the two side frames 211, and the bottom frame beam 213 is disposed at the bottom of the two side frames 211.

[0046] like Figure 1 As shown, the vertical moving mechanism 20 also includes a first guide unit 23. The first guide unit 23 includes a plurality of first guide rails 232 and a plurality of first sliders 231. In this embodiment, the first sliders 231 and the first guide rails 232 are adapted to each other, and there are four of them. The four first guide rails 232 are equally divided into two groups, and the two groups of first guide rails 232 are respectively arranged on both sides of the first frame 11 in the vertical direction, and the two first guide rails 232 in the same group are arranged on two sides of the first frame 11 opposite to each other. The four first sliders 231 are fixed in pairs on the two side frames 211 on both sides of the second frame 21, and are slidably connected with the four first guide rails 232 in a one-to-one correspondence, which can guide and limit the second frame 21 and improve the stability during the movement.

[0047] The vertical drive unit 22 is capable of driving the second frame 21 vertically. The vertical drive unit 22 includes a first motor 224, at least one first rack 221, and at least one first gear 222. The first gear 222 is rotatably mounted on the second frame 21 and connected to the first motor 224. The first rack 221 is vertically secured to the first frame 11 and meshes with the first gear 222.

[0049] like Figure 6 As shown, the vertical movement mechanism 20 also includes a height limiting unit 24. A vertical strip hole 111 is provided on the first frame 11.

The vertical movement control unit controls the locking cylinder 241 to drive the limiting rod 242 to extend the free end horizontally into the strip hole 111. The limiting rod 242 can abut against the strip hole 111 when the second frame 21 moves, thereby vertically limiting the second frame 21, improving the accuracy of the moving position, and preventing the second frame 21 from accidentally falling or rising too high and colliding with other structures, thereby improving safety during the processing.

[0050] Two horizontal movement mechanisms 30 are vertically spaced apart on the second frame 21. The transfer control unit 50 includes two horizontal movement control units, each of which controls the two horizontal movement mechanisms 30, causing them to drive the support mechanism 40 for horizontal movement toward the storage device or the glue spraying device. In this embodiment, the storage device and the glue spraying device are arranged opposite each other along a second horizontal direction, located on either side of the third guide rail 14. The second horizontal direction is perpendicular to the first horizontal direction.

[0054] like Figure 8As shown, the first guide support assembly 35 includes at least one fourth guide rail 351 and a fourth slider 352 adapted to the fourth guide rail 351. In this embodiment, two fourth guide rails 351 are symmetrically fixed on either side of the second frame 21, and both fourth guide rails 351 are arranged along the second horizontal direction; a plurality of fourth sliders 352 are symmetrically fixed on either side of the third frame 31 and respectively connected to the two fourth guide rails 351, thereby providing support for the third frame 31 and guiding it during movement.

[0055] The primary horizontal drive unit 32 includes a second rack 321, a second gear 322, and a second motor 323. The second gear 322 is rotatably mounted on the third frame 31 and is connected to the motor shaft output end of the second motor 323. The second rack 321 is securely connected to the second frame 21 and meshes with the second gear 322. The second motor 323 is mounted on the third frame 31 and is electrically connected to the transfer control unit 50. The horizontal movement control unit controls the second motor 323 to rotate the second gear 322, thereby driving the third frame 31 to move horizontally along the fourth guide rail 351 (in the second horizontal direction).

In this embodiment, there are two second guide rails 331 and two second sliders 332, each corresponding to the other and symmetrically positioned between the slide 36 and the third frame 31. This provides uniform and stable support for the slide 36 and guides it during movement.

[0059] The secondary horizontal drive unit 34 includes a screw assembly 341, a third motor 342, and a pulley transmission assembly 343. The screw assembly 341 includes a screw shaft 3411 and a nut seat 3412.

The screw shaft 3411 is rotatably arranged on the third frame 31 and is connected to the third motor 342 through the pulley transmission assembly 343. The nut seat 3412 is arranged on one side of the slide 36 and is connected to the screw shaft 3411. The third motor 342 is electrically connected to the transfer control unit. The horizontal movement control unit controls the third motor 342 to drive the screw shaft 3411 to rotate, so that the nut seat 3412 drives the slide 36 to move horizontally along the second guide rail (second horizontal direction). The secondary movement can further expand the telescopic range of the horizontal moving mechanism 30 on the basis of the primary movement. While ensuring that the pallet is transferred into place, it can make the overall structure more compact, occupy less space, and not easily interfere with the spray device and storage device, which helps the smooth progress of processing.

The rotation drive cylinder 423 is arranged at the bottom of the slide 36, and the transfer control unit 50 is electrically connected to the solenoid valve on the air pipe of the rotation drive cylinder 423. The horizontal rotation control unit controls the rotation drive cylinder 423 to drive the third rack 421 to move, driving the third gear 422 to rotate, thereby causing the support arm 41 to rotate horizontally around the end connected to the slide 36, thereby causing the support arm 41 to switch between the first rotation position and the second rotation position. In this embodiment, the rotation angle of the support arm 41 is 180° each time.

[0065] In this embodiment, the second guide support assembly 33 further includes a rotation limit block 334, which is disposed on the slide plate 36 at positions corresponding to the first rotation position and the second rotation position of the support arm 41. The rotation limit block 334 can abut against the side of the support arm 41 to limit the support arm 41.

[0066] Figure 13 2 is a schematic structural diagram of a lifting unit in an embodiment of the present invention.

[0067] like Figure 13 As shown, the supporting mechanism 40 also includes at least one lifting unit 43. The lifting unit 43 includes a lifting plate 431 and a lifting cylinder 432. The lifting cylinder 432 is arranged on the third frame 31, and the lifting plate 431 is arranged on the output end of the lifting cylinder 432, which can support the pallet during lifting. The lifting plate 431 in this embodiment is an L-shaped plate, which can abut against the side of the support plate to limit the position of the pallet, improve the stability during lifting, and avoid displacement of the pallet. The transfer control unit 50 is electrically connected to the solenoid valve on the air pipe of the lifting cylinder 432, and the horizontal rotation control unit controls the lifting cylinder 432 to drive the lifting plate 431 to rise, thereby lifting the pallet on the supporting arm 41.

[0068] In this embodiment, two lifting units 43 are symmetrically positioned on either side of the third frame 31, supporting both sides of the pallet, thereby steadily lifting the pallet and preventing tilting or shaking. The lifting units 43 work in conjunction with the support mechanism 40 to lift the pallet before rotating the support arm 41. This prevents the pallet from rotating with the support arm 41, thus preventing collisions with the third frame and other structures. The support arm 41 requires less space when rotating independently, further expanding its range of motion and making the overall structure more compact.

[0069] During the gluing process for automotive interior parts, the automatic glue transfer device 100 can transfer automotive interior parts supported on a tray between a storage device and the glue spraying device. Taking an automotive interior part as an example: before gluing, the automotive interior part to be glued needs to be transferred from the storage device to the automatic glue transfer device 100 for transfer (i.e., unloading the part), and then transferred from the automatic glue transfer device 100 to the glue spraying device (i.e., loading the part). After gluing is completed, the glued automotive interior part needs to be transferred from the glue spraying device to the automatic glue transfer device 100 for transfer (i.e., unloading the part), and then transferred from the automatic glue transfer device 100 back to the storage device (i.e., placing the part).

[0070] During storage, transfer, and gluing, automotive interior parts are supported by pallets. The storage system consists of multiple layers, each capable of storing a palletized automotive interior part. When in the storage system or gluing system, the pallet is supported from below on both sides, while the center is suspended.

[0071] Figure 14 This is a flow chart of transferring automobile interior trim parts using an automatic transfer device for spraying glue in an embodiment of the present invention. Figure 15 This is a flow chart of the automatic transfer device for spraying glue and unloading the parts in the embodiment of the present invention. Figure 16 This is a flow chart of placing parts and loading materials in an automatic transfer device for spraying glue in an embodiment of the present invention.

[0072] The following is combined with Figures 1 to 16 , describing the specific process and method of transferring automobile interior trim parts using the automatic transfer device 100 for spraying glue of the present invention:

[0073] In step S1, the transfer control unit 50 controls the vertical movement mechanism 20, one of the supporting mechanisms 40 and its corresponding horizontal movement mechanism 30 to transfer the automotive interior parts to be sprayed with glue from the storage device to the transfer device 100 for transfer, thereby completing the removal of the parts;

[0074] Step S2: The transfer control unit 50 controls the vertical movement mechanism 20, the supporting mechanism 40 on which the automotive interior parts to be sprayed are placed, and the corresponding horizontal movement mechanism 30 to transfer the automotive interior parts to be sprayed from the transfer device 100 to the spraying device, thereby completing the loading process.

[0075] Step S3: During the glue spraying process, the transfer control unit 50 controls the vertical movement mechanism 20, one of the supporting mechanisms 40, and its corresponding horizontal movement mechanism 30 to transfer the next automotive interior component to be glued from the storage device to the glue transfer device 100 for transfer, thereby completing the removal of the next automotive interior component to be glued.

[0076] Step S4: After the glue spraying is completed, the transfer control unit 50 controls the vertical moving mechanism 20, a horizontal moving mechanism 30 and its corresponding supporting mechanism 40 to transfer the glue-sprayed automotive interior parts from the glue spraying device to the glue transfer device 100 for transfer, thus completing the unloading;

[0077] Step S5: The transfer control unit 50 controls the vertical movement mechanism 20, the supporting mechanism 40 on which the automotive interior component to be sprayed is placed, and its corresponding horizontal movement mechanism 30 to transfer the next automotive interior component to be sprayed from the spraying transfer device 100 to the spraying device, thereby completing the loading of the next automotive interior component to be sprayed.

[0078] In step S6, during the glue spraying process, the transfer control unit 50 controls the vertical moving mechanism 20, the supporting mechanism 40 on which the glue-sprayed automobile decorative parts are placed, and the corresponding horizontal moving mechanism 30 to operate, and then transfers the glue-sprayed automobile interior parts from the glue-spraying transfer device 100 back to the storage device to complete the placement of the parts, and then returns to step S3 to continue to pick up the next automobile interior parts until all the automobile interior parts on the storage device have been glued.

[0079] Among them, such as Figure 15 As shown, both the picking process and the unloading process include the following sub-steps:

[0080] Step S1-1: The vertical movement control unit controls the vertical drive unit 22 to drive the second frame 21 to move vertically, adjusting one of the supporting mechanisms 40 to a suitable height corresponding to the automotive interior component to be taken from the storage device or the glue spraying device;

[0081] Step S1-2: The horizontal movement control unit controls the primary horizontal drive unit 32 of the horizontal movement mechanism 30 connected to the supporting mechanism 40 to drive the third frame 31 to move horizontally, and the secondary horizontal drive unit 34 to drive the slide 36 to move horizontally, so that the supporting arm 41 extends below the tray where the automotive interior parts to be taken are placed;

[0082] Step S1-3: the vertical movement control unit controls the vertical driving unit 22 to drive the second frame 21 to move vertically upward, so that the supporting arm 41 lifts the tray;

[0083] Step S1-4: The horizontal movement control unit controls the first-level horizontal drive unit 32 to drive the third frame 31 to move horizontally, and the second-level horizontal drive unit 34 to drive the slide 36 to move horizontally, so that the support arm 41 retracts into the second frame 21 and the tray is moved above the lifting unit 43;

[0084] In step S1-5, the horizontal rotation control unit controls the lifting unit 43 to lift the tray on the supporting arm 41, so that the tray is separated from the supporting arm 41, and then controls the rotation drive unit 42 to drive the supporting arm 41 to rotate 180° so that it faces the target placement position where the automobile interior parts need to be placed. Finally, the horizontal rotation control unit controls the lifting unit 43 to lower the tray again, so that the tray returns to the supporting arm 41.

[0085] like Figure 16 As shown, the loading and placing process includes the following sub-steps:

[0086] Step S2-1: The vertical movement control unit controls the vertical drive unit 22 to drive the second frame 21 to move vertically, adjusting the supporting mechanism 40 with the tray to a height corresponding to the target placement position on the glue spraying device or the storage device;

[0087] Step S2-2: The horizontal movement control unit controls the corresponding primary horizontal drive unit 32 of the horizontal movement mechanism 30 to drive the third frame 31 to move horizontally, and the secondary horizontal drive unit 34 to drive the slide 36 to move horizontally, thereby extending the support arm 41 into the glue spraying device or storage device, so that the tray is positioned above the target placement position.

[0088] Step S2-3: The vertical movement control unit controls the vertical drive unit 22 to drive the second frame 21 to move vertically downward, driving the supporting arm 41 to move downward. Both sides of the tray are supported by the glue spraying device or the storage device, and the supporting arm 41 is separated from the tray.

[0089] In step S2-4, the horizontal movement control unit controls the first-level horizontal driving unit 32 in the corresponding horizontal movement mechanism 30 to drive the third frame 31 to move horizontally, and the second-level horizontal driving unit 34 drives the slide 36 to move horizontally, so that the supporting arm 41 retracts into the second frame 21.

[0090] Functions and Effects of the Embodiments

[0091] According to the automatic transfer device for glue spraying provided by the present invention, the support mechanism includes a first frame; the vertical moving mechanism includes a second frame arranged on the first frame and a vertical driving unit that drives the second frame to move vertically; two horizontal moving mechanisms are arranged on the second frame at intervals in the vertical direction; the two supporting mechanisms are respectively arranged on the two horizontal moving mechanisms, and can support the tray respectively. Therefore, the vertical moving mechanism can drive the horizontal moving mechanism and the supporting mechanism arranged on the horizontal moving mechanism to vertically rise and fall, thereby adjusting to a suitable height for picking up and placing parts or loading and unloading materials. The horizontal moving mechanism can drive the supporting mechanism to move horizontally toward the storage device or the glue spraying device. The supporting mechanism includes a supporting arm that supports the tray and a rotating driving unit that drives the supporting arm to rotate toward the storage device or the glue spraying device, thereby further expanding the moving range of the transfer device, ensuring that the automotive interior parts are transferred into place, and at the same time making the structure more compact and occupying less space. The transfer control unit can control the operation of the vertical moving mechanism, the horizontal moving mechanism and the supporting mechanism, thereby realizing automatic picking up and placing parts, and loading and unloading materials.

[0092] The support mechanism also includes a third slider, a third guide rail, and a position drive unit, so that the first frame can be horizontally movably set on the third guide rail. Before the glue spraying process begins, the position drive unit can drive the first frame to move along the first horizontal direction to the corresponding storage device and glue spraying device, without the need for manual push, which is more convenient and labor-saving. The vertical moving mechanism and the horizontal moving mechanism can move the pallet in the vertical direction and the second horizontal direction respectively. The three-axis movement method allows the automatic transfer device for glue spraying to have a wider range of movement, so that the car interior parts can be smoothly transferred into place. The horizontal moving mechanism can be extended and retracted in two stages, making the overall structure more compact and taking up less space. The support arm can rotate around one end of itself, and the space required for rotation is relatively small, which further expands the range of movement and makes the overall structure more compact.

[0093] According to the automatic transfer method for spraying glue provided by the present invention, when it is necessary to spray glue on multiple automobile interior decoration parts one by one in succession, since the automatic transfer device for spraying glue has two horizontal moving mechanisms and two supporting mechanisms, after spraying glue on an automobile interior decoration part, it can be first transferred to one of the supporting mechanisms (unloading), and then the other supporting mechanism can place the next automobile decoration part on the spraying station of the spraying device (loading); while the spraying device is spraying glue on the automobile interior decoration part on the spraying station, the automatic transfer device for spraying glue puts the previous automobile decoration part sprayed with glue back into the storage device (placing the part), and then one of the supporting mechanisms can take the next automobile interior decoration part from the storage device (taking the part), and so on. Therefore, the automatic transfer device for spraying glue of the present invention can not only replace manual transfer of automobile interior decoration parts supported by a tray between the storage device and the spraying device, but also effectively save the time of taking and placing parts, reduce the waiting time of the spraying device, shorten the spraying interval, improve processing efficiency, save time and labor, have strong practicality, and have high promotion and application value.

[0094] The above embodiments are preferred examples of the present invention and are not intended to limit the scope of protection of the present invention.
