Description

Technical Field

[0001] This invention relates to the field of aluminum casting processing technology, and in particular to an aluminum casting pin pressing device. Background Technology

[0002] The casting production process includes mold making, sand mixing, molding, melting, casting, cooling and solidification, demolding and cleaning. In traditional processes, the cast liquid metal workpiece is usually allowed to solidify naturally or the cavity is transferred to a cooling zone for separate cooling.

[0003] Among them, cast aluminum parts have unparalleled advantages over other castings, such as aesthetics, light weight, and corrosion resistance. Cast aluminum parts have low density and high specific strength. Using cast aluminum parts under the same load can reduce the weight of the structure. Therefore, cast aluminum parts are widely used in the automotive industry. With the booming development of the automotive manufacturing industry, the requirements for lightweight vehicles are becoming increasingly stringent, and cast aluminum parts have a unique advantage in this regard. Automotive cast aluminum parts are generally complex in shape, with varying wall thicknesses and many internal grooves. After casting, the surface quality of the workpiece is relatively rough, and there may be burrs on the outer edge. Therefore, the workpiece must be machined before assembly and use.

[0004] After the aluminum castings are processed, screws need to be installed on them. Existing processing equipment uses a support platform to move the aluminum castings to the required position for screw installation. However, the coaxiality between the screw and the aluminum casting cannot be guaranteed during screw installation, which can easily lead to the screw tilting, damage to the screw hole, and affect the quality of the aluminum casting. Summary of the Invention

[0005] The purpose of this invention is to provide an aluminum casting pressing device to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] An aluminum casting pin pressing device includes a first processing mechanism, a second processing mechanism, and a screw mounting mechanism, and further includes a transfer mechanism for transferring the aluminum casting from the first processing mechanism to the second processing mechanism and from the second processing mechanism to the screw mounting mechanism;

[0008] The transfer mechanism includes a transfer frame, a transfer linear module is arranged along the length of the transfer frame, a transfer drive plate is installed at the drive end of the transfer linear module, a transfer lifting plate that can move longitudinally is installed on the transfer drive plate, a longitudinally arranged transfer lifting cylinder is installed on the transfer drive plate, the drive end of the transfer lifting cylinder is connected to the transfer lifting plate, and a plurality of first transfer clamps are installed on the transfer lifting plate. The first transfer clamps include a transverse clamp and a transfer clamp block that can be flipped and installed at the bottom of the transverse clamp.

[0009] The screw mounting mechanism includes a detection component and a conveying component located below the detection component. The detection component includes a detection plate and a detection hole opened on the detection plate, with a detection camera arranged above the detection hole.

[0010] The conveying assembly includes a conveying platform and a conveying support plate that moves along the length of the conveying platform. The conveying support plate is provided with a positioning fixture for positioning the aluminum casting. The conveying platform is provided with a locking assembly along its route to lock the conveying support plate that has passed the detection assembly. The locking assembly includes a locking block. The conveying support plate is provided with a locking groove for the locking block to be inserted.

[0011] The screw installation mechanism also includes an assembly mechanism arranged along the conveying assembly. The assembly mechanism includes an assembly frame located beside the conveying assembly. The assembly frame is equipped with an assembly head that can move longitudinally. The assembly head can move laterally and longitudinally. The assembly head is equipped with a rotatable assembly sleeve. A magnetic adsorption structure for picking up screws is installed inside the assembly sleeve.

[0012] The beneficial effects of this invention are: multiple first transfer fixtures work simultaneously, aluminum castings can be transferred from the outside to the first processing mechanism, aluminum castings located in the first processing mechanism can be transferred to the second processing mechanism, and aluminum castings located in the second processing mechanism are simultaneously transferred to the screw mounting mechanism; multiple aluminum castings move synchronously, and the transfer efficiency is further improved;

[0013] The transfer lifting plate can be moved vertically, i.e., in the Z-axis direction, by the transfer lifting cylinder installed on the transfer drive plate. When clamping the aluminum casting, the first transfer clamp moves until it is coaxially aligned with the aluminum casting and then moves longitudinally close to the aluminum casting. The transfer clamp can swing longitudinally to support and clamp the aluminum casting on the horizontal clamp, which can prevent the aluminum casting from falling off the first transfer clamp.

[0014] After the aluminum casting is transferred to the screw mounting mechanism by the first transfer fixture, it is fixed by the positioning fixture. Then the conveying support plate moves forward along the length of the conveying platform. When it passes the detection component, the locking block of the locking component is inserted into the locking groove of the conveying support plate. The locking block and the locking groove lock together, so the conveying support plate will not move. It can be accurately detected by the detection component. The detection camera takes pictures of the aluminum casting of the positioning fixture through the detection hole to ensure the detection effect.

[0015] Subsequently, as it passes through the assembly mechanism, the assembly sleeve is coaxially aligned with the mounting hole of the aluminum casting. The assembly sleeve of the assembly head attracts the screw, and then the screw is inserted into the mounting hole of the aluminum casting. The screw is installed into the mounting hole of the aluminum casting by rotation. The screw to be installed will not tilt or shift, which can improve its installation stability and ensure installation quality. Attached Figure Description

[0061] The present invention will now be described in detail with reference to the accompanying drawings.

[0062] like Figure 1-15 As shown, an aluminum casting pin pressing device includes a first processing mechanism 101, a second processing mechanism 102, and a screw mounting mechanism 2. It also includes a transfer mechanism 1 for transferring aluminum castings from the first processing mechanism 101 to the second processing mechanism 102 and from the second processing mechanism 102 to the screw mounting mechanism 2.

[0063] Preferably, the first processing mechanism 101 and the second processing mechanism 102 can be arranged according to the structural requirements of the aluminum casting, and can be set as cleaning station, pin assembly, pre-testing station, etc.

[0064] The transfer mechanism 1 includes a transfer frame 111, a transfer linear module 112 is provided along the length of the transfer frame 111, a transfer drive plate 113 is installed at the drive end of the transfer linear module 112, a transfer lifting plate 114 that can move longitudinally is installed on the transfer drive plate 113, and the transfer linear module 112 can drive the transfer drive plate 113 to move laterally, that is, move in the X-axis direction.

[0065] In addition, the transfer drive plate 113 is equipped with longitudinally arranged transfer lifting cylinders 115. The drive end of the transfer lifting cylinders 115 is connected to the transfer lifting plate 114. The transfer lifting plate 114 can be moved vertically, i.e., in the Z-axis direction, by the transfer lifting cylinders 115 installed on the transfer drive plate 113. The transfer lifting plate 114 is equipped with multiple first transfer clamps 12. Through the cooperation of the transfer linear module 112 and the transfer lifting cylinders 115, the aluminum casting can be clamped and lifted, and then transferred laterally to the conveyor belt assembly or the defective product unloading station.

[0066] Preferably, the transfer drive plate 113 is equipped with a longitudinally arranged transfer longitudinal guide rail 116, and a transfer longitudinal sliding seat 117 is slidably installed on the transfer longitudinal guide rail 116. The back of the lifting drive plate is connected to the transfer longitudinal sliding seat 117, which can improve the movement stability of the transfer lifting plate 114.

[0067] The first transfer clamp 12 includes a transverse clamping plate 121 and a transfer clamping block 124 that can be flipped and installed at the bottom of the transverse clamping plate 121. A guide fulcrum block 122 and a plurality of insertion posts 123 that mate with the holes of the aluminum casting are installed at the bottom of the transverse clamping plate 121. One end of the transfer clamping block 124 is provided with a support block 125 that can abut against the aluminum casting, and a first movable block 126 that can rotate is installed in the middle. The first movable block 126 is rotatably connected to the guide fulcrum block 122. The transfer clamping block 124 can swing longitudinally around the guide fulcrum block 122 and support the aluminum casting through the support block 125.

[0068] In this embodiment, when clamping the aluminum casting, the first transfer clamp 12 moves to be coaxially aligned with the aluminum casting and then longitudinally approaches the aluminum casting, so that the insertion post 123 installed at the bottom of the transverse clamping plate 121 is inserted into the hole of the aluminum casting to prevent the aluminum casting from shifting laterally; then the transfer clamping block 124 can swing longitudinally around the guide fulcrum block 122 and support the aluminum casting through the support block 125 to achieve clamping of the aluminum casting and prevent the aluminum casting from falling off the first transfer clamp 12.

[0069] Specifically, a second movable block 127 capable of rotation is installed at the other end of the transfer clamping block 124, and a longitudinal telescopic cylinder 128 is also provided on the transverse clamping plate 121. The driving end of the longitudinal telescopic cylinder 128 is rotatably connected to the second movable block 127. When clamping the aluminum casting, the piston rod of the longitudinal telescopic cylinder 128 extends, causing the second movable block 127 to descend. At this time, the transfer clamping block 124 swings around the guide fulcrum block 122 via the first movable block 126, and the support block 125 located at one end of the transfer clamping block 124 tilts up, which can support the bottom of the aluminum casting and prevent the aluminum casting from falling from the first transfer clamping fixture 12. Conversely, the longitudinal telescopic cylinder 128 retracts, and the support block 125 located at one end of the transfer clamping block 124 swings downward. At this time, the aluminum casting is not supported and can fall from the insertion post 123.

[0070] Preferably, the first movable block 126 is rotatably connected to the guide fulcrum block 122 through a shaft hole structure; the first movable block 126 is rotatably connected to the middle position of the transfer clamping block 124 through a shaft hole structure; the second movable block 127 is rotatably connected to the drive end of the longitudinal telescopic cylinder 128 and the end of the transfer clamping block 124 through shaft holes respectively; when the transfer clamping block 124 swings, the first movable block 126 and the second movable block 127 can adaptively tilt and swing, ensuring the smoothness of the swing and the stability of the clamping.

[0071] Preferably, there are three first transfer clamps 12, with adjacent first transfer clamps 12 equidistant from each other, allowing for the simultaneous clamping of three aluminum castings. The three first transfer clamps 12 operate simultaneously, enabling the aluminum castings to be transferred from the outside to the first processing mechanism 101. The aluminum castings located in the first processing mechanism 101 are then transferred to the second processing mechanism 102, and simultaneously, the aluminum castings located in the second processing mechanism 102 are transferred to the screw mounting mechanism. This synchronous movement of the aluminum castings further improves transfer efficiency.

[0072] The screw installation mechanism 2 includes a detection component 24 and a conveying component 21 located below the detection component 24. The detection component 24 includes a detection plate 244 and a detection hole 245 opened in the detection plate 244. A detection camera 249 is arranged above the detection hole 245. The conveying component 21 includes a conveying platform 211 and a conveying support plate 22 that moves along the length of the conveying platform 211. The conveying support plate 22 is provided with a positioning fixture 220 for positioning the aluminum casting. The conveying platform 211 is provided with a locking component along its path to lock the conveying support plate 22 that has passed through the detection component 24. The locking component includes a locking block 217. The conveying support plate 22 is provided with a locking groove 219 for the locking block 217 to be inserted.

[0073] The aluminum castings requiring photographic inspection are fixed by the positioning fixture 220. Then, the conveying support plate 22 moves forward along the length of the conveying platform 211. When it passes the inspection component 24, the locking block 217 of the locking component is inserted into the locking groove 219 of the conveying support plate 22. The locking block 217 and the locking groove 219 lock together, so the conveying support plate 22 will not shift and can be accurately inspected by the inspection component 24. The inspection camera 249 takes pictures of the aluminum castings in the positioning fixture 220 through the inspection hole 245 to ensure the inspection effect. When the aluminum casting is detected as defective, the conveying component 21 can retract, so that the defective aluminum casting is in contact with the first transfer fixture 12.

[0074] The conveying support plate 22 is equipped with a fitting plate 218, and a locking groove 219 is formed on the fitting plate 218. The movement direction of the locking block 217 is perpendicular to the movement direction of the conveying assembly 21. Under the drive of the locking telescopic cylinder 216, the locking block 217 can extend and lock with the locking groove 219 of the fitting plate 218 to intercept the conveying support plate 22 and prevent it from continuing to move forward, so that the detection camera 249 can accurately take pictures and detect it.

[0075] The conveying platform 211 includes a support guide rail 212 arranged along its length and a support sliding seat 213 slidably mounted on the support guide rail 212. A conveying support plate 22 is mounted on the support sliding seat 213. A belt conveyor 214 is arranged along its length on the side of the support guide rail 212. A transmission seat 215 is mounted on the long side of the belt conveyor 214 and is connected to the conveying support plate 22. The belt conveyor 214 moves under the drive of a motor, and the transmission seat 215 moves along the length of the belt conveyor 214. The conveying support plate 22, connected to the transmission seat 215, moves along the length of the support guide rail 212 via the support sliding seat 213, allowing the aluminum castings on the conveying support plate 22 to be conveyed forward through different workstations. The detection component 24 allows the detection camera 249 to take pictures and detect the workpieces, thus improving the conveying stability.

[0076] The specific positioning fixture 220 structure includes a positioning plate 221 arranged on the conveying support plate 22 and multiple positioning columns 222 formed on the top of the positioning plate 221, which mate with the holes of the aluminum casting. The positioning plate 221 is also equipped with a corner cylinder 223 that presses and positions the aluminum casting on the positioning plate 221. The driving end of the corner cylinder 223 is equipped with a pressing block 224 that can contact and mate with the top of the aluminum casting. The holes of the aluminum casting mate with the positioning columns 222 of the positioning plate 221 to limit the lateral position of the aluminum casting and prevent it from shifting laterally. Then the corner cylinder 223 works to drive the pressing block 224 to press the top of the aluminum casting, preventing the aluminum casting from shifting longitudinally and achieving complete positioning of the aluminum casting.

[0077] A buffer pad 225 is installed at the bottom of the pressing block 224. When the pressing block 224 is pressed, the buffer pad 225 contacts the aluminum casting and has a buffering effect, which can reduce the probability of collision, protect the aluminum casting, and reduce wear.

[0078] The conveyor support plate 22 is equipped with a flipping drive 23 that drives the positioning plate 221 to flip. The aluminum casting has a pin installed in the previous process. The pin is in a vertical state. Therefore, the flipping drive 23 can flip the aluminum casting by 20 degrees, so that the pin becomes a horizontal position. This makes it easier for the inspection camera 249 to take pictures of the installation length of the pin during inspection, thereby checking whether the installation of the pin meets the requirements and whether it is a qualified product.

[0079] The flipping drive 23 includes a rotating shaft 232 installed at both ends of the positioning plate 221. Bearing seats 231 for rotating the rotating shaft 232 are respectively provided on both sides of the positioning plate 221. One of the rotating shafts 232 is equipped with a gear 233. The conveying support plate 22 is slidably installed with a gear condition 234 that meshes with the gear 233. The flipping drive 23 also includes a rotating shaft 232 installed at the other end of the positioning plate 221 and a bearing seat 231 for rotating the rotating shaft 232. By moving the gear condition 234, the gear condition 234 meshes with the gear 233, and the positioning plate 221 rotates around the bearing seat 231 through the rotating shaft 232 to achieve a flip of °, which facilitates the inspection of whether the pin installation of the aluminum casting meets the requirements and whether its installation length meets the requirements.

[0080] Furthermore, the conveying support plate 22 is equipped with a drive cylinder 235 that moves the tooth condition 234 and a sliding guide rail 236 that guides the tooth condition 234 to move. The drive cylinder 235 moves the tooth condition 234 back and forth, which can move the positioning plate 221 to a vertical or horizontal position. The conveying support plate 22 is also equipped with a support positioning column for horizontal positioning support of the positioning plate 221. When the positioning plate 221 is in a horizontal position, the support positioning column precisely positions and supports the positioning plate 221, which is used for the installation and disassembly of aluminum castings.

[0081] The aluminum casting passes through the inspection assembly 24 via the forward movement of the conveying support plate 22. The inspection assembly 24 also includes a gantry support frame 240 arranged above the conveying assembly 21. The inspection plate 244 is mounted on the gantry support frame 240 with adjustable height. The gantry support frame 240 is also provided with a camera plate 246 for mounting the inspection camera 249. The height of the inspection plate 244 can be adjusted according to the size of the aluminum casting, so that the distance between the inspection hole 245 and the inspection camera 249 changes, thereby adjusting the amount of light entering the device.

[0082] Furthermore, the gantry support frame 240 includes a pair of guide columns 241. A first tensioning sleeve 242 and a second tensioning sleeve 243 are slidably mounted on the guide columns 241 and aligned coaxially. The tension of the first tensioning sleeve 242 and the second tensioning sleeve 243 relative to the guide columns 241 is adjusted by rotating bolts, facilitating adjustment of their installation height. The second tensioning sleeve 243 is located above the first tensioning sleeve 242. A detection plate 244 is mounted on the first tensioning sleeve 242, and a camera plate 246 is mounted on the second tensioning sleeve 243. When photographing and inspecting aluminum castings of different sizes, the height of the camera plate 246 can be adjusted for accurate photographing and inspection of the aluminum castings' inspection positions.

[0083] In addition, the camera plate 246 has a horizontally arranged horizontal adjustment groove 247, and a fixing plate 248 that can adjust the horizontal position is installed in the horizontal adjustment groove 247. The detection camera 249 is mounted vertically on the fixing plate 248. The horizontal position of the detection camera 249 can be adjusted by the cooperation of the fixing plate 248 and the horizontal adjustment groove 247. The horizontal position of the detection camera 249 can be finely adjusted to facilitate accurate photographic inspection of aluminum castings.

[0084] The assembly mechanism 3 includes an assembly head 32 disposed beside the conveying assembly 21. The assembly head 32 is capable of moving laterally and longitudinally. The assembly head 32 is equipped with a rotatable assembly sleeve 317. A magnetic adsorption structure 318 for picking up screws is installed inside the assembly sleeve 317.

[0085] The aluminum castings requiring screw installation are conveyed forward by the conveying assembly 21. In the conveying assembly 21, the positioning fixture 220 positions the aluminum castings on the conveying support plate 22. When passing the assembly mechanism 3, the assembly sleeve 317 is coaxially aligned with the mounting hole of the aluminum casting. The assembly sleeve 317 of the assembly head 32 attracts the screw, and then the screw is inserted into the mounting hole of the aluminum casting. The screw is installed into the mounting hole of the aluminum casting by rotation. The screws to be installed will not tilt or shift, which can improve the installation stability and ensure the installation quality.

[0086] The assembly mechanism 3 also includes an assembly gantry 311 located above the conveying assembly 21. The assembly gantry 311 is provided with a first linear module 312 arranged perpendicular to the conveying assembly 21. A vertically arranged second linear module 313 is installed at the drive end of the first linear module 312. The assembly head 32 is installed at the drive end of the second linear module 313. With the cooperation of the first linear module 312 and the second linear module 313, the assembly head 32 can move vertically and laterally to install screws into the mounting holes of the aluminum casting.

[0087] Specifically, the assembly head 32 includes a vertical drive plate 314 mounted longitudinally on the drive end of the second linear module 313. A horizontal drive plate 315 is slidably mounted on the vertical drive plate 314. A rotary servo motor 316 is mounted on the horizontal drive plate 315. The drive end of the rotary servo motor 316 is connected to the assembly sleeve 317. The rotary servo motor 316 drives the assembly sleeve 317 to rotate. The end of the magnetic adsorption structure 318 is a magnetic screw head with a magnetic adsorption effect. The magnetic screw head is inserted into the assembly sleeve 317. After the screw is adsorbed by the magnetic structure, it is then rotated to install the screw into the mounting hole of the aluminum casting.

[0088] Preferably, the vertical drive plate 314 is equipped with a longitudinally arranged longitudinal guide rail 321, and a longitudinal sliding seat 322 is slidably mounted on the longitudinal guide rail 321. The transverse drive plate 315 is equipped with a longitudinal guide rod 323, and the vertical drive plate 314 has a longitudinal guide hole 324 for the longitudinal guide rod 323 to slide through; this ensures the stability of the transverse drive plate 315 in the vertical direction. The top of the longitudinal guide rod 323 is nested with a stop sleeve 325 that cooperates with the stop of the longitudinal guide hole 324, and the longitudinal guide rod 323 is nested with a compression spring 326 located between the vertical drive plate 314 and the transverse drive plate 315; when the transverse drive plate 315 moves in the vertical direction, the compression spring 326 has a buffering effect to prevent excessive vibration amplitude from causing the screw to fall off the assembly sleeve 317.

[0089] Assembly mechanism 3 also includes a screw feeding mechanism 33 for feeding screws one by one. The screw feeding mechanism 33 includes a feeding station 332, which is equipped with a positioning clamping member 333 that can be opened and closed to hold and position the screws. A screw unloading station 338 is provided next to the feeding station 332 for unloading screws. A transverse transfer seat 336 for transferring screws is provided between the unloading station 338 and the feeding station 332. The unloading station 338 is equipped with a longitudinal... A guide seat 334 is arranged to guide the screws as they fall. The guide seat 334 is formed with a guide hole 335 for the screws to pass through. A transverse transfer seat 336 has a guide positioning hole 337 for positioning the screws. When the transverse transfer seat 336 is at the unloading station 338, the guide positioning hole 337 is coaxially aligned with the guide hole 335. When the transverse transfer seat 336 is at the loading station 332, it is coaxially aligned with the clamping end of the positioning clamp 333. The screws to be loaded fall sequentially from the vibrating plate and vibrating track onto the guide seat 334. After passing through the guide seat 334, the screws enter the guide positioning hole 337 of the transverse transfer seat 336. Then, the transverse transfer seat 336 moves laterally from the unloading station 338 to the loading station 332. After reaching the loading station 332, the screws are clamped by the positioning clamp 333 and then adsorbed by the assembly head 332.

[0090] Preferably, the positioning clamp 333 is a finger cylinder, which can open and close to clamp and position the screw.

[0091] The screw feeding mechanism 33 also includes a feeding support plate 331. The unloading station 338 and the feeding station 332 are both set on the feeding support plate 331. The feeding support plate 331 is provided with a transfer drive component 34 that drives the transverse transfer seat 336 to move between the unloading station 338 and the feeding station 332. The transfer drive component 34 includes a bottom guide rail 341 and a bottom sliding seat 342 that is slidably installed on the bottom guide rail 341. The transverse transfer seat 336 is installed on the top of the bottom sliding seat 342. The feeding support plate 331 is equipped with a transverse telescopic cylinder 343 that is arranged parallel to the bottom guide rail 341. The driving end of the transverse telescopic cylinder 343 is equipped with a bottom drive plate 344, and the bottom drive plate 344 is connected to the transverse transfer seat 336. In this embodiment, the transverse telescopic cylinder 343 drives the transverse transfer seat 336 connected to the bottom drive plate 344 to slide laterally along the bottom guide rail 341 through the bottom sliding seat 342, that is, to slide between the unloading station 338 and the loading station 332, so as to transfer and load the screws to be installed.

[0092] Preferably, the feeding support plate 331 is also provided with bottom limiting seats 345 located on both sides of the bottom guide rail 341. The transverse transfer seat 336 moves laterally between the two bottom limiting seats 345. The bottom limiting seats 345 are equipped with buffers 346 that elastically contact the transverse transfer seat 336. When the transverse transfer seat 336 moves laterally between the two bottom limiting seats 345 and approaches the bottom limiting seats 345, the buffers 346 make buffer contact with the transverse transfer seat 336. On the one hand, this prevents the transverse transfer seat 336 from exceeding its travel when it moves. On the other hand, when the transverse transfer seat 336 approaches the bottom limiting seats 345, the buffers 346 can make elastic contact with the transverse transfer seat 336 to reduce the vibration caused by the collision and prevent the screws from falling out of the guide positioning holes 337.

[0093] In addition, a qualified product unloading station 137 is installed at one end of the conveyor platform 211, and a defective product unloading station 136 is installed at the other end of the conveyor platform 211.

[0094] The first transfer fixture 12 can transfer defective products from the conveyor platform 211 to the defective product unloading station 136. Specifically, aluminum castings are defective products before entering the bolt installation mechanism 2. The transfer mechanism 1 directly transfers the defective products to the defective product unloading station 136 on the side via the first transfer fixture 12 for direct unloading. Alternatively, it can be transferred to the bolt installation mechanism 2 via the first transfer fixture 12. After entering the bolt installation mechanism 2, the aluminum casting components are moved forward along the conveyor platform 211 via the positioning fixture 42 and continue to the side of the qualified product unloading station 137 for unloading. This achieves classified unloading, prevents mixing, and improves unloading efficiency.

[0095] A material unloading and transfer robot 13 is installed between the conveying platform 211 and the qualified product unloading station 137.

[0096] The unloading and transfer robot 13 includes a second transfer fixture 131 that can move along the length of the conveying platform 211 and longitudinally. The structure of the second transfer fixture 131 is the same as that of the first transfer fixture 12. The second transfer fixture 131 of the unloading and transfer robot 13 can transfer products from the conveying platform 211 to the qualified product unloading station 137 for unloading, thereby realizing classified unloading.

[0097] Preferably, the unloading and transfer robot 13 further includes an unloading linear module 132. The drive end of the unloading linear module 132 is equipped with an unloading stand 133. The unloading stand 133 is longitudinally arranged with an unloading cylinder 134. The drive end of the unloading cylinder 134 is equipped with an unloading drive plate 135. The second transfer fixture 131 is installed at the bottom of the unloading drive plate 135. With the cooperation of the unloading linear module 132 and the unloading cylinder 134, the second transfer fixture 131 can move in the Y-axis direction and the Z-axis direction, and can move between the conveying platform 211 and the qualified product unloading station 137 to unload the aluminum casting.

[0098] Furthermore, the defective product unloading station 136 and the qualified product unloading station 137 have the same structure, and both use a conveyor to advance and unload the aluminum castings.

[0099] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0100] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
