[0025] (iii) Beneficial effects.

[0026] The present invention provides an assembly line for producing automotive door interior panels, which has the following advantages compared with the prior art.

[0027] 1) A complete automated production line for automotive door interior panels is formed, which can automatically complete operations such as injection molding, cutting, punching, grinding, inspection, drilling and coding of automotive door interior panels. It has a high degree of automation and low labor intensity. The overall equipment layout is reasonable and compact, the material turnover is completed automatically, the turnover stroke is short and the turnover cost is low.

[0028] 2) The rubber-cutting device, through the cooperation of the rubber-cutting gripper, rubber-cutting assembly, and punching gripper, can achieve automated rubber-cutting of interior panels. It has a high degree of automation, low labor intensity, and high rubber-cutting efficiency. During rubber-cutting, the rubber-cutting gripper can use either the first or second clamping structure according to the workpiece type to place the workpiece on the front door positioning module or the rear door positioning module. When it is a front door workpiece, the C-shaped flip plate flips to the outside, and when it is a rear door workpiece, the C-shaped flip plate flips to the inside. After the rubber-cutting is completed, the punching gripper can use either the third or fourth clamping structure according to the workpiece type to unload the workpiece. It can achieve rubber-cutting of both the front and rear doors with the same rubber-cutting assembly, without the need to change molds, resulting in low cost, small space occupation, and convenient use.

[0029] 3) The quick-change module allows for precise positioning and installation of workpieces, while the rotating frame loads and unloads workpieces simultaneously, improving grinding efficiency. A grinding robot arm drives the grinding spindle to adjust its position, which in turn drives the grinding head for grinding, resulting in excellent grinding quality and high efficiency. Simultaneously, a dust collection component adsorbs the powder during grinding, providing good performance. This system automates grinding operations, reducing manual labor and increasing efficiency. A quick-change installation section houses the quick-change module, enabling rapid mold changes for positioning modules, facilitating mold-change production of similar products and maximizing resource utilization. A locking mechanism, using a locking seat and locking head for locking and an I-shaped support base and support rollers for support, ensures reliable locking and stable support, preventing the rotating frame from shifting during grinding and guaranteeing grinding quality. The dust collection component, using a dust collection cart and air pipe, provides excellent dust collection, ensuring safety during use, and concentrating powder within the dust collection cart for easy cleaning.

[0065] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0066] See Figures 1 to 28 The present invention provides a production line for producing automotive door interior panels, including a baking device 1, an injection molding device 2, a rubber cutting device 3, a punching device 4, a grinding device 5, an inspection device 6, a drilling device 7, and a coding device 8.

[0067] See Figure 1 and Figure 2Baking equipment 1 is located at the front center of the production line to bake the sheet metal to facilitate subsequent injection molding. The sheet metal is fed by a robotic arm. Injection molding equipment 2 is symmetrically positioned behind baking equipment 1. Injection molding equipment 2 is equipped with injection molds for die-casting the baked sheet metal. The injection molds are existing technology and are used for injection molding automotive door interior panels.

[0068] See Figures 2 to 5 A shearing device 3 is installed between two injection molding machines 2. It includes a shearing gripper 31, a shearing assembly 32, and a punching gripper 33 arranged sequentially. The shearing gripper 31 is positioned close to the injection molding machine 2 and is used to grip the molded product in the injection molding machine 2 and feed it to the shearing assembly 32. The punching gripper 33 is positioned close to the punching machine 4 and is used to grip the sheared product in the shearing assembly 32, mark it at the marking device 8, and then feed it into the punching machine 4. The shearing assembly 32 is used to cut the workpiece's glue opening. It includes a fixed plate 321 and front and rear door modules for mounting the front and rear door workpieces, respectively. A C-shaped lifting plate 322 is mounted on the fixed plate 321 and can be raised and lowered. One side of the C-shaped lifting plate 322 has a C-shaped flip plate 323 that can be flipped. The front door module is mounted on the C-shaped lifting plate 322, and part of the rear door module is mounted on the C-shaped lifting plate 322, while the other part is mounted on the C-shaped flip plate 323. The fixed plate 321 is equipped with multiple scissor sets 324 corresponding to the glue outlet and multiple clamping parts 325 for clamping the workpiece.

[0069] See Figure 1 and Figure 2 The punching equipment 4 is symmetrically installed on both sides of the punching gripper 33, and is used to punch the contour of the cut rubber workpiece. The grinding device 5 is installed on the rear side of the punching equipment 4, and is used to grind the punched workpiece. The inspection device 6 is installed on the rear side of the grinding device 5, and includes a weighing inspection device for quality inspection of the workpiece and a visual inspection device for appearance inspection of the workpiece. The weighing inspection device can be an electronic scale, and the visual inspection device is existing technology and will not be described in detail in this embodiment. The drilling device 7 is installed on the rear side of the inspection device 6, and is used to punch air holes on the workpiece for attaching the skin. The marking device 8 is installed between the cut rubber 32 assembly and the punching gripper 33, and is used to mark and mark the workpiece. Among them, the baking equipment 1 is a double-layer flat oven, the injection molding equipment 2 is a vertical injection molding machine, the punching equipment 4 is a trimming punching machine, the drilling equipment 7 is a laser drilling machine, and the marking device 8 is a laser marking machine.

[0070] During manufacturing, a robotic arm can load the sheet material into the baking equipment 1. After baking, the robotic arm can place the sheet material into the injection mold of the injection molding equipment 2, where it is die-cast. Once the workpiece is formed, a shearing gripper 31 picks up the formed product from the injection molding equipment 2 and feeds it into a shearing assembly 32. The shearing assembly 32 shears the glue at the workpiece's glue opening. Then, a punching gripper 33 picks up the sheared product from the shearing assembly 32, marks it at the marking equipment 8, and sends it into the punching equipment 4. After punching, the robotic arm can send the workpiece into the grinding device 5 for grinding. After grinding, the robotic arm can send the workpiece into the inspection equipment 6 for weighing and visual inspection. Finally, the robotic arm can send the qualified workpiece into the punching equipment 7 for punching.

[0071] In some embodiments, such as Figure 6 , Figure 8 and Figure 9 As shown, the front door module includes multiple front door positioning blocks 3261 mounted on a C-shaped lifting plate 322 and arranged along the outer contour of the front door workpiece 9. A first positioning pin 3262 and a positioning plate 3263 are mounted on the C-shaped lifting plate 322. When the workpiece is the front door workpiece 9, it is mounted on the front door module. To prevent interference, the C-shaped flip plate 323 flips to the outside, and the front door workpiece 9 rests between the multiple front door positioning blocks 3261, respectively engaging with the first positioning pin 3262 and the positioning plate 3263.

[0072] The rear door module includes L-shaped positioning components 3271 symmetrically arranged on a C-shaped lifting plate 322 and rear door positioning blocks 3272 symmetrically arranged on both sides of a C-shaped flip plate 323. One side of one rear door positioning block 3272 is fitted with a second positioning pin 3273, and the other side is fitted with a positioning pin 3274. When the rear door workpiece 10 is in use, the C-shaped flip plate 323 flips inward, and the rear door workpiece 10 is installed onto the rear door module. One side of the rear door workpiece 10 abuts against the two L-shaped positioning components 3271, and the other side abuts against the two rear door positioning blocks 3272, respectively engaging with the second positioning pin 3273 and the positioning pin 3274. Through the cooperation of the C-shaped lifting plate and the C-shaped flip plate, the same cutting assembly can be used to cut the glue for both the front and rear doors without changing the mold, resulting in low cost, small space occupation, and ease of use.

[0073] In some embodiments, such as Figure 4 , Figure 7 and Figure 10As shown, the clamping component 325 includes a Z-shaped seat 3251 fixed on a fixed plate 321 and a column 3252 mounted on the Z-shaped seat 3251. A support rod 3253 and a rotating pressure block 3254 are respectively installed at the head end of the column 3252. The support rod 3253 can be screwed and threaded to the top of the column 3252 for easy adjustment of the support height. The body of the rotating pressure block 3254 is hinged to a cylinder, and one end of the rotating pressure block is connected to the cylinder's telescopic rod. During clamping, the support rod supports the bottom of the workpiece's inverted structure, and the rotating pressure block presses against the upper side of the inverted structure, resulting in good clamping effect and preventing workpiece displacement during rubber cutting.

[0074] An adjusting rail 328 is mounted on the upper side of the fixed plate 321. The scissor assembly 324 includes an adjusting seat 3241 that can be adjusted along the adjusting rail 328. The adjusting seat 3241 can be connected to the adjusting rail 328 via fasteners. The adjusting rail is provided with a sliding groove for the fasteners to slide. A vertical adjusting rod 3242 is mounted on the adjusting seat 3241, and a horizontal adjusting rod 3243 is mounted on the vertical adjusting rod 3242. A pneumatic scissor 3244 corresponding to the nozzle is mounted at the end of the horizontal adjusting rod 3243.

[0075] In some embodiments, such as Figures 12 to 15 As shown, the rubber-cutting gripper 31 includes a horizontally sliding slide 311, a rubber-cutting robot 312 mounted on the slide 311, and a first clamp 313 mounted on the end of the rubber-cutting robot 312. The first clamp 313 has a first clamping structure 314 and a second clamping structure 315. The rubber-cutting gripper 31 can use the first clamping structure 314 or the second clamping structure 315 to clamp the workpiece according to the workpiece type and place it on the corresponding front door module or rear door module. The punching gripper 33 includes a punching robot 331 and a second clamp 332 mounted on the end of the punching robot 331. The second clamp 332 has a third clamping structure 333 and a fourth clamping structure 334. The punching gripper 33 can use the third clamping structure 333 or the fourth clamping structure 334 to clamp the workpiece according to the workpiece type and place it in the punching equipment.

[0076] The first gripping structure 314 and the second gripping structure 315 are respectively installed on both sides of the cross 316, which is installed at the end of the rubber cutting robot 312. The first gripping structure 314 and the second gripping structure 315 have the same structure, both including multiple main grippers 3141 and a first top post 3142 installed on the cross 316. Scrap gripping assemblies for gripping the scrap edges of the workpiece are respectively installed on both sides of the cross 316. The scrap gripping assemblies include multiple fixed claws 3143 spaced apart and multiple movable claws 3144 corresponding to the fixed claws 3143. The movable claws 3144 can move towards the fixed claws 3143 to clamp.

[0077] The third and fourth clamping structures are located on both sides of the T-shaped frame 335, which is mounted on the end of the punching robot 331. The third clamping structure 333 and the fourth clamping structure 334 have the same structure, both including mounting rods 3331 fixed at both ends of the T-shaped frame 335 and gripper cylinders 3332 mounted at both ends of the mounting rods 3331. A second top column 3333 is installed between the two gripper cylinders 3332, and the gripper cylinders 3332 cooperate with the second top column 3333 to clamp the workpiece.

[0078] During the cutting process, the cutting gripper 31 uses either the first or second clamping structure to clamp the workpiece according to its type and places it on the corresponding front or rear door module. During clamping, the main jaw holds the workpiece, the first top post supports the workpiece, and the movable jaw moves towards the fixed jaw to clamp the waste edges on both sides of the workpiece. Then, the cutting robot 312 moves the workpiece and waste edges towards the cutting assembly 32. During this movement, the waste clamping assembly releases, causing the waste edges to fall off. When the workpiece is a front door workpiece 9, the C-shaped flip plate 323 flips to the outside, positioning the front door workpiece 9 on the front door module. The front door workpiece rests against the front door positioning block and is inserted into the first positioning pin and positioning plate.

[0082] During grinding, the quick-change module 52 is pushed to the quick-change mounting part 511 of the rotating frame 51 via an external mold-changing trolley, with the guide hole inserted at the end of the trolley. Then, under the action of the rolling balls, the quick-change module is moved from the trolley to the quick-change mounting part, placing the positioning pin in the positioning hole. The locking rod is inserted and locks the positioning seat plate, and the mold pressure block is pressed against the positioning seat plate. A robotic arm is used to position the workpiece on the positioning block structure of the positioning seat plate. The rotating frame rotates 180 degrees, sending the workpiece located on the outer side to the grinding assembly. During the rotating feeding process, the inclined guide surfaces on both sides of the I-shaped support seat guide the support rollers to abut against the lower end of the I-shaped support seat. Then, the locking head moves towards the locking seat, inserting and locking itself inside the locking seat, thereby locking the rotating frame. The grinding robot drives the grinding spindle to adjust its position, and the grinding spindle drives the grinding head to rotate and grind the workpiece. During the grinding process, the air nozzle blows the ground powder towards the dust collection trolley. Under the suction force of the dust collection trolley, the powder is collected inside. After grinding is completed, the locking head retracts, disengaging from the locking seat and unlocking the rotating frame. While the rotating frame is feeding material, the ground workpiece located at the grinding assembly rotates to the outside to facilitate unloading.
