Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the following embodiments are described in detail with reference to the accompanying drawings.

[0033] Example

[0034] Figure 1 This is a structural diagram of an adhesive spraying equipment for automotive interior parts.

[0035] like Figure 1As shown, this embodiment provides an automotive interior parts adhesive spraying device, including a material cart 10, an AGV trolley 20, a material cart positioning mechanism 30 (not shown in the figure), a pallet detection component 40, a transfer device 50, and an adhesive spraying device 60. The material cart 10, AGV trolley 20, material cart positioning mechanism 30, and pallet detection component 40 are arranged on one side of the transfer device 50. This side of the transfer device 50 has at least one parking position for the material cart 10. The material cart 10 is driven in and out of the parking position by the AGV trolley 20. The material cart 10 is used to store multiple automotive interior parts supported by pallets 1 in layers. The material cart positioning mechanism 30 and pallet detection component 40 are arranged at the parking position, respectively used to fix the position of the material cart 10 and detect the position and quantity of pallets 1 on the material cart 10. The adhesive spraying device 60 is arranged on the other side of the transfer device 50, having an adhesive spraying position corresponding to the parking position. The adhesive spraying device 60 is used to spray adhesive onto the automotive interior parts supported by the pallets 1. The transfer device 50 is used to transfer automotive interior parts supported by the pallet 1 between the material cart 10 located at the docking position and the glue spraying device 60.

[0036] Figure 2 This is a structural diagram of the material cart 10, AGV trolley 20, material cart positioning mechanism 30, and pallet detection component 40. Figure 3 This is a structural schematic diagram of the material cart 10 and the material cart positioning mechanism 30.

[0037] like Figure 2 and Figure 3 As shown, the material cart 10 includes a frame 11, a plurality of support plates 12 disposed on the frame 11, and a plurality of casters 13 disposed at the bottom of the frame 11.

[0038] In this embodiment, the frame 11 is a square frame structure with an open top and one side, forming an opening for placing and removing the tray 1. A crossbar 111 is located near the opening at the bottom of the frame. Multiple support plates 12 are evenly spaced vertically in pairs on the frame 11. The two support plates 12 in each group are symmetrically positioned on either side of the opening in the horizontal direction to support one tray 1. Each support plate 12 is an L-shaped strip with multiple adhesive holes distributed along its length. Four casters 13 are located at the four corners of the bottom of the frame 11; the casters 13 are swivel casters.

[0039] Each support plate 12 is also equipped with a limiting block 14, which can block the side 31 of the pallet 1 to prevent the pallet 1 from shifting horizontally. In this embodiment, each support plate 12 has a limiting block 14 at both ends. The distance between the two limiting blocks 14 is adapted to the width of the pallet 1, which can limit the pallet 1 in the horizontal direction of entering and exiting the opening, thus preventing the pallet 1 from shifting. The height of the limiting block 14 near the opening is smaller than the height of the other limiting block 14, so that the limiting block 14 near the opening can support the pallet 1 when it is horizontally transferred, facilitating its horizontal transfer. The top of the adjacent sides of the two limiting blocks 14 are also chamfered, so that the pallet 1 transferred to the support plate 12 falls between the two limiting blocks 14.

[0040] The AGV trolley 20 lifts the material cart 10 by jacking it up from the bottom of the frame 11, thereby enabling the material cart 10 to move along a set route.

[0041] Figure 4 This is a schematic diagram of the material cart positioning mechanism 30.

[0042] like Figure 4 As shown, the material cart positioning mechanism 30 mainly includes a mounting base 31, a blocking component 32, a lifting guide rail 33, a lifting drive component 34, and a limiting component 35, all installed at the parking position. In the following text, the direction in which the material cart 10 enters and exits the parking position is defined as the first horizontal direction, and the direction perpendicular to the first horizontal direction is defined as the second horizontal direction.

[0043] The mounting base 31 is fixed to the ground and includes a base plate 311 and two side plates 312 vertically fixed to the base plate 311. The two side plates 312 are distributed along a first horizontal direction. A blocking member 32 is installed on the top of the side plate 312 located rearward in the direction the material trolley 10 enters the parking position. The blocking member 32 is positioned directly opposite the direction the material trolley 10 enters the parking position and is used to block the crossbar 111 at the bottom of the frame 11. The side plate 312 located forward in the direction the material trolley 10 enters the parking position is lower than the crossbar 111 at the bottom of the frame 11 to avoid collision with the frame 11. A lifting guide rail 33 is installed on this side plate 312.

[0044] The lifting drive component 34 is mounted on the base plate 311 with its output end facing upward. In this embodiment, the lifting drive component 34 is a cylinder.

[0045] The limiting member 35 is installed on the slider of the lifting guide rail 33 and connected to the output end of the lifting drive member 34. The limiting member 35 is driven by the lifting drive member 34 to move up and down along the lifting guide rail 33. The lifting drive member 34 and the limiting member 35 are configured such that when the lifting member 35 is raised, the top of the limiting member 35 is higher than the lower surface of the crossbar 111, and when the lifting member 35 is lower than the lower surface of the crossbar 111, the limiting member 35 can cooperate with the blocking member 32 to block both sides of the crossbar 111, thereby achieving positioning of the material cart 10 in the first horizontal direction.

[0046] In this embodiment, the limiting member 35 has two vertically adjacent sides 351, respectively arranged corresponding to the first horizontal direction and the second horizontal direction. For example... Figure 3 As shown, two rolling elements 36 are installed on the crossbar 111 at the bottom of the frame 11, which cooperate with the two sides 351 of the limiting member 35. This prevents the crossbar 111 from making hard contact with the lifting limiting member 35. The rolling elements 36 can be rollers or bearings. The top of the two sides 351 of the limiting member 35 is also provided with chamfers 352, which can reduce the impact when in contact with the two rolling elements 36.

[0047] Furthermore, such as Figure 2 and Figure 3 As shown, in this embodiment, there are two material cart positioning mechanisms 30, distributed along the second horizontal direction. Four rolling elements 36 are provided on the crossbar 111, with each pair of rolling elements 36 corresponding to one material cart positioning mechanism 30. The limiting elements 35 of the two material cart positioning mechanisms 30 have their corresponding sides 351 facing away from each other in the second horizontal direction. This allows the material cart 10 to be positioned in the second horizontal direction when the two raised limiting elements 35 engage with the corresponding rolling elements 36 on the crossbar 111.

[0048] like Figure 2 As shown, the pallet detection assembly 40 includes a stand plate 41 and multiple pallet detection sensors 42.

[0049] The upright plate 41 is fixed to the ground. Multiple pallet detection sensors 42 are evenly spaced vertically on the upright plate 41, each corresponding to one of the multiple sets of support plates 12 on the material cart 10. Each pallet detection sensor 42 detects whether a pallet 1 is stored on its corresponding support plate 1, thus enabling the multiple pallet detection sensors 42 to detect the number of pallets 1 on the material cart 10. In this embodiment, the pallet detection sensor 42 is a proximity sensor.

[0050] Figure 5 This is a schematic diagram of the transfer device 50.

[0051] like Figure 5As shown, the transfer device 50 includes a support mechanism 51, a lifting mechanism 52, two horizontal moving mechanisms 53, and two supporting mechanisms 54. The support mechanism 51 primarily supports the other mechanisms. The lifting mechanism 52 is mounted on the support mechanism 51, and the two horizontal moving mechanisms 53 are arranged parallel to each other on the lifting mechanism 52 and are driven by the lifting mechanism 52 to move up and down. The two supporting mechanisms 54 are respectively mounted on the two horizontal moving mechanisms 53 and are driven by the corresponding horizontal moving mechanisms 53 to move horizontally. Each supporting mechanism 54 supports one pallet 1.

[0052] Figure 6 This is a structural schematic diagram of the support mechanism 51.

[0053] like Figure 6 As shown, the support mechanism 51 mainly includes a first frame 511 that provides support and has a rectangular structure.

[0054] In this embodiment, the support mechanism 51 further includes a support guide rail 512 and a support drive unit 513. The support drive unit 513 can drive the first frame 511 to move along the support guide rail 512, so that the first frame 511 can be aligned with different stopping positions. Specifically, the support guide rail 512 is a linear guide rail arranged along the second horizontal direction, and the bottom of the first frame 511 is mounted on the slider of the support guide rail 512. The support drive unit 513 includes a reduction motor 5131, a fourth gear 5132, and a fourth rack 5133. The reduction motor 5131 is mounted on the bottom of the first frame 511 and its output shaft is arranged vertically downward. The fourth gear 5132 is mounted on the output shaft of the reduction motor 5131 and meshes with the fourth rack 5133 arranged along the second horizontal direction.

[0055] Figure 7 This is a structural schematic diagram of the lifting mechanism 52.

[0056] like Figure 7 As shown, the lifting mechanism 52 mainly includes a second frame 521, a lifting guide rail 522, and a lifting drive unit 523.

[0057] The second frame 521 includes two side frames 5211, a top frame beam 5212, and a bottom frame beam 5213. The side frames 5211 are hexagonal in shape, formed by combining trapezoids and rectangles. The two side frames 5211 are arranged opposite each other at a certain distance in the second horizontal direction. The top frame beam 5212 is connected to the top of the two side frames 5211, and the bottom frame beam 5213 is connected to the bottom of the two side frames 5211.

[0058] The lifting guide rail 522 is a linear guide rail arranged in the vertical direction, and multiple lifting guide rails 522 are symmetrically distributed on both sides of the first frame 511 (see...). Figure 5The second frame 521 is mounted on the sliders of the corresponding side lifting guide rails 522 on both sides. In this embodiment, there are four lifting guide rails 522, with two lifting guide rails 522 on each side of the first frame 511.

[0059] The lifting drive unit 523 can drive the second frame 521 to move along the lifting guide rail 522, so that the horizontal moving mechanism 53 and the supporting mechanism 54 on the lifting mechanism 52 can be aligned vertically with the pallet pick-up and drop positions on the material cart 10 and the glue spraying device 60. Specifically, the lifting drive unit 523 includes a motor 5231, a dual-shaft reducer 5232, two drive shafts 5233, two first gears 5234, and two first racks 5235. Among them, the dual-shaft reducer 5232 is installed at the center of the top frame beam 5212 of the second frame 521. The input end of the dual-shaft reducer 5232 is connected to the output shaft of the motor 5231. The two output shafts of the dual-shaft reducer 5232 are arranged on both sides of the first frame 511 and are respectively connected to one end of the two drive shafts 5233. The two drive shafts 5233 are respectively mounted on the top frame beam 5212 through bearing seats, and the other end of each drive shaft 5233 is equipped with a first gear 5234. Two first racks 5235 are respectively installed on both sides of the first frame 511 in a vertical direction and mesh with the first gears 5234 on the corresponding sides.

[0060] In this embodiment, a plurality of strip-shaped holes 5111 are provided on each side of the first frame 511 at intervals along the vertical direction. The lifting mechanism 52 also includes a lifting limiting unit 524 that cooperates with the strip-shaped holes 5111 on the first frame 511. The lifting limiting unit 524 includes a locking cylinder 5241 and a limiting rod 5242. The cylinder body of the locking cylinder 5241 is installed at the end position of the top frame beam 5212 of the second frame 521. The piston rod of the locking cylinder 5241 is coaxially connected with the limiting rod 5242. The locking cylinder 5241 can drive the limiting rod 5242 to extend horizontally into the strip-shaped hole 5111, thereby limiting the second frame 521 in the vertical direction. This can improve the accuracy of the position of the second frame 521 when it is raised and lowered, and also prevent the second frame 521 from accidentally falling or rising too high and colliding with other structures, thereby improving the safety of the lifting mechanism 52 when it is raised and lowered.

[0061] Figure 8 This is a schematic diagram of the structure of the first-stage horizontal drive unit 533 of the horizontal moving mechanism 53. Figure 9 This is a schematic diagram of the structure of the secondary horizontal drive unit 536 of the horizontal moving mechanism 53.

[0062] Each horizontal moving mechanism 53 can drive the supporting mechanism 54 on it to move along a first horizontal direction. Each horizontal moving mechanism 53 includes a third frame 531, a primary horizontal guide rail 532, a primary horizontal drive unit 533, a sliding plate 534, a secondary horizontal guide rail 535, and a secondary horizontal drive unit 536.

[0063] like Figure 8 As shown, the third frame 531 is a hexagonal shape formed by splicing a trapezoid and a rectangle, and the long base of the trapezoid coincides with the long side of the rectangle.

[0064] The first-level horizontal guide rail 532 is a linear guide rail set along the first horizontal direction. The two first-level horizontal guide rails 532 are respectively set on the two side frames 5211 of the second frame 521. The two sides of the third frame 531 are respectively mounted on the sliders of the two first-level horizontal guide rails 532.

[0065] The primary horizontal drive unit 533 can drive the third frame 531 to move along the primary horizontal guide rail 532, realizing primary horizontal movement. Specifically, the primary horizontal drive unit 533 includes a geared motor 5331, a second gear 5332, and a second rack 5333. The geared motor 5331 is installed on the side of the third frame 531, and the output shaft of the geared motor 5331 is arranged vertically and connected to the second gear 5332. The second rack 5333 is arranged on the corresponding side frame 5211 along the first horizontal direction and meshes with the second gear 5332.

[0066] like Figure 9 As shown, the secondary horizontal guide rail 535 is a linear guide rail arranged along the first horizontal direction. In this embodiment, the two secondary horizontal guide rails 535 are arranged in parallel on the third frame 531, and the slide plate 534 is straddled and installed on the slider of the two secondary horizontal guide rails 535.

[0067] The secondary horizontal drive unit 536 can drive the slide plate 534 to move along the secondary horizontal guide rail 535, achieving secondary horizontal movement based on the primary horizontal movement. Specifically, the secondary horizontal drive unit 536 includes a motor 5361, a pulley drive assembly 5362, and a lead screw and nut assembly 5363. The motor 5361 is mounted on the third frame 531, and its output shaft is connected to the lead screw via the pulley drive assembly 5362. The pulley drive assembly 5362 includes a driving pulley connected to the output of the motor 5361, a driven pulley connected to the lead screw, and a synchronous belt fitted onto the driving and driven pulleys. The lead screw and nut assembly 5363 includes a lead screw and a lead screw nut. The lead screw is mounted on the third frame 531 along the first horizontal direction via a lead screw seat, and the lead screw nut is connected to the slide plate 534 via a connector.

[0068] As can be seen, the two-stage horizontal movement design of the horizontal movement mechanism 53 not only expands the horizontal movement range, but also makes the structure more compact and occupies less space. It is also less likely to collide with the material cart 10 and the glue spraying device 60 when performing horizontal transfer operations, which helps to ensure the smooth progress of the transfer operation.

[0069] Figure 10 This is a schematic diagram of the supporting arm 541 of the supporting mechanism 54 when it is in the first rotational position. Figure 11 This is a schematic diagram of the supporting arm 541 of the supporting mechanism 54 when it is in the second rotational position. Figure 12 This is a schematic diagram of the rotary drive unit 542.

[0070] like Figure 10 and Figure 11 As shown, each support mechanism 54 is mounted on the slide plate 534 of the horizontal moving mechanism 53, and includes a support arm 541 and a rotary drive unit 542.

[0071] One end of the support arm 541 is rotatably mounted on the slide plate 534, enabling it to support the tray 1 from the bottom. In this embodiment, the support arm 541 has an octagonal frame structure, and the maximum width of the support arm 541 is less than the width of the tray 1.

[0072] The rotary drive unit 542 is mounted on the slide plate 534 and is capable of driving the support arm 541 to rotate horizontally. Specifically, as shown... Figure 12 As shown, the rotary drive unit 542 includes a rotary drive cylinder 5421, a third rack 5422, a third gear 5423, and a connecting shaft 5424. The rotary drive cylinder 5421 is mounted on the bottom surface of the slide plate 534. The third rack 5422 is arranged parallel to the piston rod of the rotary drive cylinder 5421 and connected to the piston rod via a connector. The third gear 5423 meshes with the third rack 5422 and is connected to one end of the support arm 541 via the connecting shaft 5424, which is rotatably mounted on the slide plate 534.

[0073] In this embodiment, the rotation drive unit 542 drives the support arm 541 to rotate alternately at +180° and -180°, corresponding to two rotation positions for the support arm 541, namely the first rotation position and the second rotation position, see... Figure 10 and Figure 11 The support mechanism 54 also includes a rotation limiter 54335, which is block-shaped and mounted on the slide plate 534. The rotation limiter 54335 limits the rotation of the support arm 541 by blocking the side 351 of the support arm 541.

[0074] To prevent the pallet 1 from rotating when the support arm 541 rotates, thus avoiding collisions with other structures, the support mechanism 54 also includes a lifting unit 544. The lifting unit 544 mainly includes a lifting cylinder 5441 and a lifting plate 5442. The lifting cylinder 5441 is mounted on the third frame 531, and the lifting plate 5442, driven by the lifting cylinder 5441, can lift the pallet 1. In this embodiment, two lifting cylinders 5441 are symmetrically installed on both sides of the third frame 531. The piston end of each lifting cylinder 5441 is vertically upward and connected to a lifting plate 5442 positioned along a first horizontal direction. The two lifting plates 5442, driven by their respective lifting cylinders 5441, can smoothly lift the pallet 1 from both sides. Each lifting plate 5442 is an L-shaped strip plate, which can block the side of the pallet 1 in the second horizontal direction, preventing the pallet 1 from moving in that direction when lifted. The bottom of each lifting plate 5442 is also connected to multiple vertically arranged guide shafts 5443. Each guide shaft 5443 is guided and engaged with a corresponding guide bearing installed on the third frame 531 to ensure the stability of the lifting plate 5442 when it is raised or lowered.

[0075] Figure 13 This is a schematic diagram of the adhesive spraying device 60.

[0076] like Figure 13 As shown, the glue spraying device 60 includes a glue spraying robot 61 and a glue spraying support plate 62.

[0077] In this embodiment, the glue spraying device 60 has multiple glue spraying positions arranged along the second horizontal direction. Each glue spraying position corresponds to a docking position. Each glue spraying position is provided with a glue spraying robot 61 and two glue spraying support plates 62 arranged on both sides below the glue spraying robot 61. The two glue spraying support plates 62 can support the tray 1 from both sides. The glue spraying robot 61 can spray glue on the automotive interior parts supported on the tray 1.

[0078] This automotive interior parts adhesive spraying equipment also includes a control system that can control the operation of the AGV trolley 20, the material cart positioning mechanism 30, the pallet detection component 40, the transfer device 50, and the adhesive spraying device 60.

[0079] Taking a material cart 10 with multiple pallets 1, each pallet 1 supporting a clamp and a car interior part to be sprayed with adhesive, as an example, the working process of this car interior part adhesive spraying equipment is described below.

[0080] First, the AGV trolley 20 delivers the material cart 10 to a parking position next to the transfer device 50. At the parking position, the material cart positioning mechanism 30 positions the material cart 10, including positioning in a first horizontal direction and positioning in a second horizontal direction, ensuring the material cart 10 is in a fixed position. After positioning, the pallet detection sensor 42 of the pallet detection assembly 40 detects whether a pallet 1 is stored at the corresponding horizontal position on the material cart 10, and sends information including the position and quantity of the pallets 1 to the control system.

[0081] Next, the transfer device 50 first aligns with the parking position of the material cart 10, and then takes a pallet 1 from the material cart 10. After taking the pallet 1, the transfer device 50 adjusts according to the glue spraying position of the glue spraying device 60, and after adjustment, puts the taken pallet 1 into the glue spraying position.

[0082] Then, the glue-spraying robot 61 of the glue-spraying device 60 sprays glue onto the automotive interior parts on the tray 1. During the glue-spraying process, the transfer device 50 removes the next tray 1 from the material cart 10 according to the aforementioned steps. Before placing it into the glue-spraying position, the control system first determines whether the transfer device 50 needs to remove the tray 1 from the glue-spraying position first. If so, the transfer device 50 removes the tray 1 from the glue-spraying position first, and then places the next tray 1 into the glue-spraying position. For the tray 1 that has already been removed from the glue-spraying position, the transfer device 50 places it into the material cart 10. If not, the transfer device 50 directly places the next tray 1 into the glue-spraying position. After the glue-spraying process is completed, the transfer device 50 places the tray 1 into the material cart 10.

[0083] In this way, the transfer device 50 cyclically performs the transfer operation of picking up and putting down the pallet 1 from the material cart 10 or the glue spraying device 60, and the glue spraying device 60 continuously performs glue spraying operation at short intervals, which can complete the glue spraying processing operation of all automotive interior parts supported by the pallet 1 on the material cart 10.

[0084] The alignment of the transfer device 50 with the material cart 10 is achieved by the support mechanism 51. Specifically, the support drive unit 513 drives the first frame 511 to move along the support guide rail 512, so that the first frame 511 is aligned with the material cart 10.

[0085] The process of the transfer device 50 picking up pallet 1 is as follows: Step 1: The lifting mechanism 52 operates, and the lifting drive unit 523 drives the second frame 521 to rise and fall, so that the support arm 541 of the support mechanism 54 is adjusted to a suitable height corresponding to the pallet 1 to be picked up; Step 2: The horizontal moving mechanism 53 operates, and the first-level horizontal drive unit 533 drives the third frame 531 to move horizontally, and the second-level horizontal drive unit 536 drives the slide plate 534 to move horizontally, so that the support arm 541 of the support mechanism 54 extends below the pallet 1 to be picked up; Step 3: The lifting mechanism 52 operates, and the lifting drive unit 523 drives the second frame 521 to rise, so that the support arm 541 lifts the pallet 1; Step 4: The horizontal moving mechanism 53 operates, and the first-level horizontal drive unit 533 drives the third frame 531 to move horizontally in the opposite direction, and the second-level horizontal drive unit 536 drives the slide plate 534 to move horizontally in the opposite direction, so that the support arm 541 returns to the second frame 521, and the pallet 1 is located above the lifting unit 544.

[0086] Before transferring pallet 1 to the opposite side of the side where pallet 1 is located, the transfer device 50 adjusts according to the glue spraying device 60 or the material cart 10 on the opposite side as follows: Step 1: The supporting mechanism 54 operates, and the lifting unit 544 first lifts the pallet 1 on the supporting arm 541, so that the pallet 1 is separated from the supporting arm 541; Step 2: The horizontal moving mechanism 53 operates, and the secondary horizontal drive unit 536 drives the sliding plate 534 to move horizontally to adjust the position of the supporting arm 541, so as to facilitate the subsequent rotation of the supporting arm 541; Step 3: The supporting mechanism 54 operates, and the rotation drive unit 542 drives the supporting arm 541 to rotate +180° or -180°; Step 4: The horizontal moving mechanism 53 operates, and the secondary horizontal drive unit 536 drives the sliding plate 534 to move horizontally to adjust the position of the rotated supporting arm 541, so that it corresponds with the pallet 1; Step 5: The supporting mechanism 54 operates, and the lifting unit 544 then lowers the pallet 1, so that the pallet 1 is placed back on the supporting arm 541. This adjustment of the support arm 541 ensures that when the pallet 1 is subsequently stored, the support arm 541 can extend horizontally into the glue spraying device 60 or the material cart 10 on the opposite side.

[0087] The process of placing pallet 1 using transfer device 50 is as follows: Step 1: Lifting mechanism 52 operates, lifting drive unit 523 drives second frame 521 to lift, adjusting support arm 541 supporting pallet 1 to a suitable height corresponding to the support plate at the target placement position; Step 2: Horizontal movement mechanism 53 operates, first-level horizontal drive unit 533 drives third frame 531 to move horizontally, and second-level horizontal drive unit 536 drives slide plate 534 to move horizontally, extending support arm 541 and pallet 1 on it to the support plate at the target placement position. Above the plate 12; Step 3, the lifting mechanism 52 works, the lifting drive unit 523 drives the second frame 521 to descend, and the support arm 541 descends accordingly, so that the pallet 1 is placed on the support plate 12 at the target placement position, and the support arm 541 is separated from the pallet 1; Step 4, the horizontal moving mechanism 53 works, the first-level horizontal drive unit 533 drives the third frame 531 to move horizontally in the opposite direction, and the second-level horizontal drive unit 536 drives the slide plate 534 to move horizontally in the opposite direction, so that the support arm 541 returns to the second frame 521.

[0088] The role and effect of the embodiments

[0089] The automotive interior trim adhesive spraying equipment according to this embodiment includes a transfer device, a material cart, a material cart positioning mechanism, a pallet detection component, and an adhesive spraying device. The material cart can store multiple automotive interior trim parts supported by pallets in layers, and the automotive interior trim parts before and after adhesive spraying are stored through the material cart. The material cart positioning mechanism and the pallet detection component are located on one side of the transfer device, respectively fixing the position of the material cart and detecting the position and quantity of the pallets on the material cart. The adhesive spraying device is located on the other side of the transfer device. The transfer device transfers the automotive interior trim parts supported by pallets between the material cart and the adhesive spraying device. The transfer device includes a support mechanism, a lifting mechanism, two horizontal moving mechanisms, and two supporting mechanisms. During operation, the material cart is fixed in position by the material cart positioning mechanism. A transfer device is positioned between the material cart and the glue spraying device. Through its support mechanism, lifting mechanism, and horizontal movement mechanism, it drives the supporting mechanism to pick up and place automotive interior parts supported by pallets. The glue spraying device then performs the glue spraying operation. This cycle of "picking up parts from the material cart, placing parts on the glue spraying device, spraying glue, picking up parts again, and placing parts back on the material cart" is achieved, enabling the glue spraying of multiple automotive interior parts. Therefore, this automotive interior part glue spraying equipment replaces manual labor with mechanical equipment, realizing centralized picking up and placing, rapid transfer, and glue spraying of automotive interior parts. In particular, the transfer device has two horizontal movement mechanisms and two supporting mechanisms, enabling alternating picking and placing, thus shortening the time interval between glue spraying operations and significantly improving processing efficiency.
