[0051] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0052] Please refer to Figure 1 — Figure 12 , a die-casting production line, including a die-casting machine 1, further including:

[0053] A melting furnace 2, inside which a slag filtering and mixing mechanism 21 is provided. The waste materials are mixed through the slag filtering and mixing mechanism 21, and the waste materials are melted into metal liquid through the melting furnace 2;

[0054] A ladling unit 3, the ladling unit 3 includes a ladling robot 31 and a ladle 32. The ladle 32 is driven to move by the ladling robot 31, and the metal liquid is poured into the die-casting machine 1 for die-casting;

[0055] A part picking unit 4, the part picking unit 4 includes a part picking robot 41 and a part picking mechanism 42;

[0056] The recycling conveyor line 5 is arranged on one side of the die-casting machine 1. The recycling conveyor line 5 and the melting furnace 2 are arranged in a linear array. The ladling unit 3 is arranged between the melting furnace 2 and the die-casting machine 1. The workpiece taking unit 4 is arranged between the recycling conveyor line 5 and the die-casting machine 1. The workpiece taking mechanism 42 is driven by the workpiece taking robot 41 to take out the workpiece in the die-casting machine 1.

[0057] Specifically, the die-casting machine 1 is a conventional die-casting device in the prior art, and its structure and working principle are both in the prior art, so no further description will be given here.

[0058] The melting furnace 2 is arranged on one side of the die-casting machine 1. The raw materials and waste materials are melted into metal liquid by the melting furnace 2. A slag filtering and mixing mechanism 21 is arranged inside the melting furnace 2. The slag filtering and mixing mechanism 21 mixes the input waste materials and the metal liquid obtained by melting the raw materials inside the melting furnace 2 to ensure that the metal liquid obtained by melting the raw materials and the melted waste materials can be fully mixed, that is, the metal liquid obtained by melting the raw materials contains a part of the melted waste materials, namely the mixed metal liquid.

[0059] The ladling unit 3 is arranged between the melting furnace 2 and the die-casting machine 1. The ladling unit 3 includes a ladling robot 31 and a ladle 32. The ladling robot 31 is a conventional robot arm in the prior art. The ladle 32 is arranged at the output end of the ladling robot 31. The ladling robot 31 drives the ladle 32 to move, so that the mixed metal liquid can be scooped out from the melting furnace 2 and transferred to the input end of the die-casting machine 1 for pouring. Through the cooperation of the ladling unit 3 and the melting furnace 2, automatic feeding of the die-casting machine 1 can be realized, replacing manual pouring, greatly reducing the labor intensity of workers and improving the production safety.

[0060] The recycling conveyor line 5 is arranged on one side of the die-casting machine 1. Preferably, the recycling conveyor line 5 is arranged on the same side as the melting furnace 2. The workpiece taking unit 4 is arranged between the recycling conveyor line 5 and the die-casting machine 1. The workpiece taking unit 4 includes a workpiece taking robot 41 and a workpiece taking mechanism 42. The workpiece taking robot 41 drives the workpiece taking mechanism 42 to move between the die-casting machine 1 and the recycling conveyor line 5. The workpiece taking robot 41 is a conventional robot arm in the prior art. Through the workpiece taking mechanism 42, the workpiece completed in the die-casting machine 1 can be taken out and placed on the recycling conveyor line 5, and then transported to the manual operation position through the recycling conveyor line 5 for waste removal. After waste removal, the waste is transported back to the melting furnace 2 through the recycling conveyor line 5.

[0061] In this invention, the waste materials and the molten metal inside the melting furnace 2 are mixed in sequence through the slag filtering and mixing mechanism 21 of the melting furnace 2. The ladle robot 31 of the pouring section 3 drives the ladle 32 to move to ladle out a part of the molten metal from the melting furnace 2 and pour it into the die-casting machine 1 for die-casting. After die-casting is completed, the workpiece-taking robot 41 of the workpiece-taking section 4 drives the workpiece-taking mechanism 42 to take out the die-cast workpiece from the die-casting machine 1 and place it on the recycling and transportation line 5. After the waste materials are manually removed, the waste materials are transported back to the melting furnace 2 again. It can realize the automatic die-casting and workpiece-taking of the workpiece and the recycling of the waste materials after workpiece-taking, can reduce the cost of producing die-castings for electronic products or die-castings in other fields while ensuring a certain quality, and thus can improve the economic benefits.

[0062] As an embodiment provided by the present invention, as Figure 3 and Figure 4 shown, there are a blocking baffle 211, a filtering baffle 212, a pressing mechanism 213 and a pushing mechanism 214. The metal liquid level inside the melting furnace 2 is divided into a first area 22, a second area 23 and a third area 24 by the blocking baffle 211 and the filtering baffle 212. Specifically, both ends of the filtering baffle 212 are fixedly connected to both sides inside the melting furnace 2, one end of the blocking baffle 211 is fixedly connected to the filtering baffle 212, and the other end is fixedly connected to the melting furnace 2. Further, the width of the filtering baffle 212 is greater than the width of the blocking baffle 211, that is, the position of the end of the filtering baffle 212 inside the melting furnace 2 is lower than the position of the end of the blocking baffle 211 inside the melting furnace 2 inside the melting furnace 2. The pressing mechanism 213 and the pushing mechanism 214 are both arranged on the melting furnace 2. The output end of the pressing mechanism 213 is located above the first area 22, and the output end of the pushing mechanism 214 is located inside the second area 23. Filtering holes 25 are opened on the filtering baffle 212, and the third area 24 is communicated with the second area 23 through the filtering holes 25.

[0063] During the production process, the first area 22 is the input area for waste materials. The waste materials are input into the first area 22 of the melting furnace 2 through the recycling and transportation line 5. After the waste materials are input into the first area 22, the output end of the pressing mechanism 213 pushes the preliminarily melted waste material blocks in the first area 22 downward. Since the depth of the filtering baffle 212 is greater than the depth of the blocking baffle 211, the waste material blocks will flow to the second area 23. After the waste material blocks flow to the second area 23, the output end of the pushing mechanism 214 pushes the waste material blocks in the second area 23 to flow and flow into the third area 24 through the filtering holes 25 on the filtering baffle 212 for the pouring section 3 to ladle.

[0064] The filter holes 25 provided on the filter baffle 212 can restrict the passage of waste blocks in the second area 23, prevent excessive waste blocks from passing through at one time and affecting the metal liquid components in the third area 24, ensure the performance of the metal liquid for die casting, and ensure the performance of the finally produced die-cast parts. At the same time, since part of the waste is mixed, the overall production cost can be reduced, and the raw material cost for die casting can be reduced without affecting the performance of the final product.

[0065] As a further embodiment provided by the present invention, as Figure 4 shown, the downward pressing mechanism 213 includes a vertical support base 2131, a first slider 2132, a first connecting rod 2133, a vertical driving unit 2134 and a lower pressing plate 2135. The vertical support base 2131 is fixedly installed on the melting furnace 2. The first slider 2132 is slidably connected to the outer wall of the vertical support base 2131. The vertical driving unit 2134 is fixedly installed on the vertical support base 2131, and the output end of the vertical driving unit 2134 penetrates and extends into the interior of the vertical support base 2131. The output end of the vertical driving unit 2134 is connected to the first slider 2132. The first connecting rod 2133 is specifically an "L" - shaped structure. One end of the first connecting rod 2133 is fixedly connected to the first slider 2132, and the other end is fixedly connected to the lower pressing plate 2135. The vertical driving unit 2134 can be a cylinder, an oil cylinder or an electric driving unit, etc., which are mechanical components or mechanisms that can satisfy driving the first slider 2132 to keep vertical lifting. The lower pressing plate 2135 is circular to ensure a certain downward pressing area.

[0066] During the production process, the vertical driving unit 2134 drives the first slider 2132 to lift vertically on the vertical support base 2131, and then drives the lower pressing plate 2135 on the first connecting rod 2133 to lift vertically, and presses the lower pressing plate 2135 into the liquid level of the first area 22 in the melting furnace 2.

[0067] As a further embodiment provided by the present invention, the pushing mechanism 214 includes a horizontal support base 2141, a second slider 2142, a horizontal driving unit 2143, a vertical base 2144, a third slider 2145, a second connecting rod 2146, a pushing plate 2147 and a vertical driving mechanism 2148. The horizontal support base 2141 is fixedly installed on the melting furnace 2. The second slider 2142 is slidably connected to the horizontal support base 2141. The horizontal driving unit 2143 is fixedly installed on the horizontal support base 2141. The output end of the horizontal driving unit 2143 penetrates and extends into the interior of the horizontal support base 2141. The output end of the horizontal driving unit 2143 is fixedly connected to the second slider 2142. The second slider 2142 can be driven by the horizontal driving unit 2143 to move inside the horizontal support base 2141. The vertical base 2144 is fixedly installed on the second slider 2142. The third slider 2145 is slidably connected to the interior of the vertical base 2144. The vertical driving mechanism 2148 is fixedly installed on the vertical base 2144, and the output end of the vertical driving mechanism 2148 is connected to the third slider 2145. The second connecting rod 2146 is specifically an "L" - shaped structure. One end of the second connecting rod 2146 is fixedly connected to the third slider 2145, and the other end is fixedly connected to the pushing plate 2147. The horizontal driving unit 2143 and the vertical driving mechanism 2148 can both be cylinders, oil cylinders or electric driving units, which are mechanical components capable of driving the second slider 2142 and the third slider 2145 to move linearly.

[0068] During the production process, after the waste blocks in the first area 22 flow into the second area 23, the vertical driving mechanism 2148 is used to drive the third slider 2145 to move downward, so that the pushing plate 2147 extends into the metal liquid surface in the second area 23. Subsequently, the horizontal driving unit 2143 is used to drive the second slider 2142 to move, thereby driving the vertical base 2144 to move, and enabling the pushing plate 2147 to move in the horizontal direction, and pushing the metal liquid and waste blocks in the second area 23 through the filter holes 25 into the third area 24.

[0069] As a further embodiment provided by the present invention, as Figure 8 and Figure 9As shown in the figure, the ladling part 3 further includes a connecting base 33, a connecting rod 34 and a detection rod 35. Specifically, the connecting base 33 is fixedly connected to the output end of the ladling robot 31. A connecting hole 331 is formed at one end of the connecting base 33 away from the ladling robot 31. One end of the connecting rod 34 is fixedly connected to the inside of the connecting hole 331. A connecting ear 321 is fixedly arranged on the ladle 32. Preferably, the number of the connecting ears 321 is two, and the two connecting ears 321 are respectively fixedly arranged on both sides of the ladle 32. One end of the connecting rod 34 away from the connecting base 33 is fixedly connected to one of the connecting ears 321 on the ladle 32. The detection rod 35 is fixedly connected to the connecting base 33, and the liquid level height is detected by the detection rod 35.

[0070] The detection rod 35 is specifically a metal guide rod, which is connected to the connecting base 33 through an insulating block and is electrically connected to an external relay. The melting furnace 2 is electrically connected to the external relay. When the ladling part 3 is ladling, the ladle 32 contacts the molten metal inside the melting furnace 2. At this time, the detection rod 35 contacts the molten metal, making the entire detection circuit conductive, and the relay emits a signal.

[0071] As an embodiment provided by the present invention, the ladle 32 is integrally made of ductile iron and can be used normally under the high temperature of molten aluminum.

[0072] As Figure 16 shown in the figure, the front end of the ladle 32 is small and the rear end is large. The smaller front end can enable the molten metal to quickly enter the inside of the ladle 32 during the process of the ladling robot 31 driving the ladle 32 to rotate for ladling. At the same time, when ladling and casting for the die casting machine 1, when pouring outwards, the molten metal can be more concentrated at the front end, so that the molten metal is not easily spilled out during the ladling process. The larger rear end can ensure that the ladle 32 has a sufficient volume inside, and the bottom of the ladle 32 is arc-shaped, which can carry more soup materials during the ladling process, so as to be able to carry the soup volume required for various products, having a certain compatibility. At the same time, the molten metal at the rear end applies a force to the front end to assist the ladling robot 31 in ladling.

[0073] Furthermore, as Figure 16As shown, the angle A between the inner wall of the front end of the ladle 32 and the center line of the ladle 32 is 35° - 45°, preferably 40.77°. The distance between the front end of the ladle 32 and the center line of the ladle 32 is 100 mm - 110 mm, preferably 104.02 mm. A pouring port 322 is provided at the front end of the ladle 32. The angle of the pouring port 322 is 23° - 30°, preferably 26.67°. The width of the pouring port 322 is 65 mm - 75 mm, preferably 69.98 mm, and the depth is 6 mm - 10 mm, preferably 8.59 mm. This ensures that when pouring, the molten metal converges towards the front end during the flow process and flows out at a certain angle, guaranteeing that the molten metal inside the ladle 32 can be completely poured out. The angle B between the inner wall of the rear end of the ladle 32 and the center line of the ladle 32 is 10° - 20°, preferably 16°. The distance between the rear end of the ladle 32 and the center line of the ladle 32 is 70 mm - 78 mm, preferably 74 mm. The distance from the top end to the bottom end of the ladle 32 is 90 mm - 98 mm, preferably 94 mm. In this form, the ladle 32 can fully imitate manual operations during the actions of scooping and pouring soup. And in cooperation with the soup-feeding robot 31 to drive the ladle 32 to move, it can completely replace the manual actions of scooping and feeding soup, reducing the labor intensity of workers and lowering the labor cost.

[0074] As an embodiment provided by the present invention, during the production process of the ladle 32, it is necessary to soak it in a high-temperature anti-sticking aluminum coating to firmly integrate the ladle 32 with the coating, preventing the aluminum melt from adhering to the inner wall of the ladle 32 during the pouring process.

[0075] As an embodiment provided by the present invention, as Figure 5 、 Figure 6 and Figure 7 shown, the workpiece picking part 4 further includes a support plate 44 installed at the output end of the picking robot 41. The picking mechanism 42 is connected to the outer wall of the support plate 44. The picking mechanism 42 includes a clamping rod 421 and a three-finger gripper 422. The three-finger gripper 422 is fixedly installed on the support plate 44. The clamping rod 421 is connected to the output end of the three-finger gripper 422. The clamping rod 421 is specifically an "L" - shaped structure. The "L" - shaped clamping rod 421 and the three-finger gripper 422 cooperate to better grasp the handle of the workpiece, ensuring a stable grip.

[0076] It should be noted that the three-finger gripper 422 can be replaced according to different die-cast workpieces, and can be replaced with an ordinary gripper or other gripper models.

The number of the detection support rods 46 is at least two. In the embodiment provided by the present invention, the number of the detection support rods 46 is two. When picking up a workpiece, after the three-finger gripper 422 grabs the workpiece, the detection support rod 46 abuts against the outer wall of the workpiece. At this time, the relay, the two detection support rods 46 and the workpiece can be electrically connected, and thus a signal can be given to the picking robot 41.

[0078] In the embodiment provided by the present invention, as Figure 5 shown, the picking part 4 further includes a spraying mechanism 43. The spraying mechanism 43 is connected to the output end of the picking robot 41 through the support plate 44. The support plate 44 can be driven to rotate by the output end of the picking robot 41, and then the spraying pipe 431 can be driven to rotate, so as to realize spraying on all angles of the workpiece. The spraying mechanism 43 specifically includes a spraying pipe 431, a first uniform plate 432, a second uniform plate 433 and a connecting plate 434. Specifically, the first uniform plate 432 is fixedly installed on the second uniform plate 433, the second uniform plate 433 is fixedly installed on the connecting plate 434, and the spraying pipe 431 is fixedly installed on the connecting plate 434. Specifically, the number of the spraying pipes 431 is several, and several spraying pipes 431 are linearly arrayed on the connecting plate 434. In the preferred embodiment provided by the present invention, the spraying pipes 431 are distributed in two rows on the connecting plate 434, and multiple spraying pipes 431 are all connected to the inside of the second uniform plate 433.

[0079] The spraying pipe 431 is made of pure copper material and has a certain plasticity. In the actual production process, customers can adjust the angle of the spraying pipe 431 according to production requirements to achieve the spraying effect that best fits the products in the on-site production.

[0080] In a further embodiment provided by the present invention, as Figure 12 shown, a liquid joint 4321 and a gas joint 4322 are fixedly installed on the first uniform plate 432. A plurality of liquid distribution holes 4323 are formed inside the first uniform plate 432. The liquid joint 4321 on the first uniform plate 432 is connected to a water pump, and the gas joint 4322 is connected to an air pump. An air control valve is arranged between the liquid joint 4321 and the water pump to control whether the liquid joint 4321 passes liquid. A liquid distribution groove 435 is formed inside the first uniform plate 432. Specifically, the liquid distribution groove 435 is a waist-shaped hole, and the number of the liquid distribution grooves 435 is several. A plurality of liquid distribution holes 4323 are linearly arrayed. In the embodiment provided by the present invention, the number of the liquid distribution grooves 435 is four, as Figure 7As shown in the figure, four liquid separation tanks 435 are symmetrically distributed on the outer wall of one side of the first uniform plate 432 with respect to the XY axis of the first uniform plate 432. A liquid separation pipe 436 is fixedly installed inside the first uniform plate 432. Specifically, the number of liquid separation pipes 436 is two. One of the liquid separation pipes 436 penetrates through two liquid separation tanks 435. On both sides of the circumferential outer wall of the liquid separation pipe 436, a first liquid separation hole 437 and a second liquid separation hole 438 are respectively formed. As Figure 13 shown, as the first embodiment of the second liquid separation hole 438 provided by the present invention, specifically, the number of the second liquid separation holes 438 is several. The several second liquid separation holes 438 are linearly arrayed on the outer wall of the liquid separation pipe 436. The liquid joint 4321 is communicated with the first liquid separation hole 437. The aperture of the first liquid separation hole 437 is larger than that of the second liquid separation hole 438. During the production process, when the liquid from the liquid joint 4321 enters the liquid separation pipe 436 through the first liquid separation hole 437, the liquid flows inside the liquid separation pipe 436 and is preliminarily split through the second liquid separation holes 438 on the liquid separation pipe 436, and the water flow is preliminarily split. The gas joint 4322 connected to the first uniform plate 432 can send gas into the liquid separation tank 435 of the first uniform plate 432 through an air pump. A gas channel is formed between the liquid separation pipe 436 and the inner wall of the liquid separation tank 435. An embedding groove is formed on the outer wall of one side of the second uniform plate 433. A rubber strip is arranged inside the embedding groove. After the first uniform plate 432 is installed on the second uniform plate 433, the rubber strip is located between the first uniform plate 432 and the second uniform plate 433, and the first uniform plate 432 and the second uniform plate 433 are sealed through the rubber strip.

[0081] As Figure 14 shown, as the second embodiment of the second liquid separation hole 438 provided by the present invention, the number of the second liquid separation holes 438 on the liquid separation pipe 436 is eight, and the eight second liquid separation holes 438 are symmetrically distributed in pairs on the liquid separation pipe 436. The two middle second liquid separation holes 438 are 90° vertical holes, and are successively 100° - 110°, 125° - 135°, 140° - 150° outward in turn. In this range, the effect of splitting can be achieved. Preferably, the specific angles outward in turn are 105°, 130° and 145°. As Figure 14 shown, the multiple second liquid separation holes 438 diverge outward in turn in the length cross-section direction of the liquid separation pipe 436. After the liquid enters the first liquid separation pipe 436 through the first liquid separation hole 437, it is quickly split to both sides through the multiple second liquid separation holes 438, and the speed of liquid splitting can be improved.

[0082] As Figure 15As shown, as the third embodiment of the second liquid separation hole 438 provided by the present invention, the number of the second liquid separation holes 438 on the liquid separation pipe 436 is eight, and the eight second liquid separation holes 438 are symmetrically distributed in pairs on the liquid separation pipe 436. The middle two second liquid separation holes 438 are 90° vertical holes, and are 100°-110°, 125°-135°, 140°-150° respectively towards one side in sequence. In this range, the effect of achieving liquid separation can be satisfied. Preferably, the specific angles outwards are 105°, 130° and 145° in sequence. Please refer to Figure 15 , it should be noted that the 90° vertical hole is the angle on the cross-section of the liquid separation pipe 436, and 105°, 130° and 145° are the angles inclined towards one side in the circumferential direction. When the liquid enters the inside of the liquid separation pipe 436 through the first liquid separation hole 437, it can enter the inside of the liquid separation tank 435 through the multiple second liquid separation holes 438 distributed at an angle around the circumferential wall of the liquid separation pipe 436, so that the liquid is in a swirling flow during the flowing process, and can make the liquid flow more evenly into the inside of the liquid separation tank 435.

[0083] As Figure 14 and Figure 15 shown, as the optimal embodiment of the second liquid separation hole 438 provided by the present invention, the number of the second liquid separation holes 438 on the liquid separation pipe 436 is eight, and the eight second liquid separation holes 438 are symmetrically distributed in pairs on the liquid separation pipe 436. The middle two second liquid separation holes 438 are 90° vertical holes, and are 100°-110°, 125°-135°, 140°-150° respectively outwards in sequence in the length cross-section direction of the liquid separation pipe 436. In this range, the effect of achieving liquid separation can be satisfied. Preferably, the specific angles outwards are 105°, 130° and 145° in sequence. The angles inclined towards one side in the circumferential direction of the liquid separation pipe 436 are 100°-110°, 125°-135°, 140°-150°. In this range, the effect of achieving liquid separation can be satisfied. Preferably, the specific angles outwards are 105°, 130° and 145° in sequence. When the liquid enters the inside of the liquid separation pipe 436 through the first liquid separation hole 437, since the eight second liquid separation holes 438 are radially distributed in the length cross-section of the liquid separation pipe 436, the liquid can be quickly separated to both sides. At the same time, since the multiple second liquid separation holes 438 are circumferentially arrayed in the axial direction of the liquid separation pipe 436, the liquid can flow in an arc surface, and thus the liquid flow is more uniform. In this embodiment, the circumferential cross-section of the liquid separation pipe 436 is the same as that of the third embodiment, and the axial cross-section diagram is similar to that of the second embodiment.

[0084] As a further embodiment provided by the present invention, as Figure 7As shown in the figure, liquid passage grooves 439 are formed inside the second uniform plate 433. Specifically, the number of liquid passage grooves 439 is two, and the two liquid passage grooves 439 are symmetrically arranged. A spiral flow dividing rod 430 is fixedly installed inside the liquid passage groove 439. The pitch of the spiral flow dividing rod 430 is 1 mm - 3 mm, preferably 2 mm; the depth of the thread is 1 mm - 2 mm, preferably 1.6 mm; and the inclination angle is 40° - 50°, preferably 45°. Liquid guiding grooves 4341 are formed on the outer wall of the connecting plate 434. Specifically, the number of liquid guiding grooves 4341 is two, and the two liquid guiding grooves 4341 are symmetrically arranged on the connecting plate 434. A plurality of spray pipes 431 installed on the connecting plate 434 are respectively communicated with the two liquid guiding grooves 4341.

[0085] During use, the water pump inputs liquid into the liquid distribution pipe 436 of the first uniform plate 432 through the liquid joint 4321, and the liquid is preliminarily divided through the first liquid distribution holes 437 and the second liquid distribution holes 438 on the liquid distribution pipe 436. Subsequently, the liquid enters the liquid distribution tank 435 of the first uniform plate 432. Then, the air pump transports gas into the liquid distribution tank 435 through the gas joint 4322, and the liquid is sprayed onto the spiral flow dividing rod 430 inside the second uniform plate 433 through the gas, and the second-step flow division is carried out through the spiral grooves 4301 formed on the spiral flow dividing rod 430. The liquid flows towards both ends of the spiral flow dividing rod 430 through the spiral grooves 4301, and enters the liquid guiding grooves 4341 of the connecting plate 434 under the action of the gas, and finally flows into each spray pipe 431 through the liquid guiding grooves 4341, realizing the third-step flow division, and finally obtaining a uniform and delicate spray. During the part-taking process, the spray can be evenly sprayed on the inner wall of the mold, so that the release agent can be evenly attached to the inner wall of the mold, and the situation of excessive accumulation in a certain corner will not occur.

[0086] The length of the liquid distribution tank 435 is 25 - 35 mm, the width is 10 - 15 mm, and the depth is 13 mm. The outer diameter of the liquid distribution pipe 436 is 6 - 8 mm, the inner diameter is 3 - 4.7 mm. The radius of the first liquid distribution hole 437 is 2 - 2.5 mm, and the radius of the second liquid distribution hole 438 is 1 - 1.25 mm. The distance between every two of one group of the second liquid distribution holes 438 is 8 - 10 mm, and the distance between the two groups of the second liquid distribution holes 438 is 15 - 20 mm. The two groups of the second liquid distribution holes 438 are symmetrical with respect to the first liquid distribution hole 437. The length of the liquid passage groove 439 is 280 - 380 mm, the width is 6 - 8 mm, and the depth is 8 - 10 mm. The length of the liquid guiding groove 4341 is 280 - 380 mm, the width is 8 - 10 mm, and the depth is 10 - 15 mm.

[0087] As an embodiment provided by the present invention, the length of the liquid separation tank 435 is 34 mm, the width is 14 mm, the depth is 13 mm, the outer diameter of the liquid separation pipe 436 is 8.7 mm, the inner diameter is 4.7 mm, the radius of the first liquid separation hole 437 is 2.5 mm, the radius of the second liquid separation hole 438 is 1.25 mm. The distance between every two of one group of the second liquid separation holes 438 is 10 mm, the distance between the two groups of the second liquid separation holes 438 is 20 mm, and the two groups of the second liquid separation holes 438 are symmetric with respect to the first liquid separation hole 437. The length of the liquid passing through tank 439 is 368 mm, the width is 8 mm, the depth is 10 mm, and the length of the liquid guiding tank 4341 is 370 mm, the width is 10 mm, and the depth is 13 mm.

[0088] As an embodiment provided by the present invention, as Figure 10 and Figure 11 shown, the recycling and transportation line 5 includes a first conveyor belt 51, a second conveyor belt 52, and a cold air fan 53. Specifically, the first conveyor belt 51 and the second conveyor belt 52 are vertically arranged, the first conveyor belt 51 is located above the second conveyor belt 52, the cold air fan 53 is fixedly installed on the first conveyor belt 51. Specifically, the cold air fan 53 is fixedly installed on the first conveyor belt 51 through a bracket. The blanking baffle 54 is installed on the second conveyor belt 52, and the blanking baffle 54 is located on one side of the first conveyor belt 51. A blanking hole is opened on the blanking baffle 54. One end of the second conveyor belt 52 is located above the melting furnace 2, and a discharge baffle 55 is fixedly installed at the end of the second conveyor belt 52 close to the melting furnace 2. Both the first conveyor belt 51 and the second conveyor belt 52 are conventional conveyor belts in the prior art.

[0089] During the production process, the picking part 4 places the workpiece taken out from the die-casting machine 1 on the first conveyor belt 51, and conveys the workpiece to the blanking baffle 54 through the first conveyor belt 51. During the conveying process, the workpiece is cooled by the cold air fan 53. After the workpiece reaches the blanking baffle 54, the handle is removed manually to obtain the finished workpiece, and the waste handle is placed on the second conveyor belt 52 through the blanking hole. The waste handle is conveyed towards the melting furnace 2 through the second conveyor belt 52, and the waste handle is put into the first area 22 of the melting furnace 2 through the discharge baffle 55 arranged at the end of the second conveyor belt 52.

[0090] A die-casting production process of a die-casting production line includes the following steps:

[0091] The die-casting machine 1 closes the mold in place. Subsequently, the ladling robot 31 receives the pouring signal and drives the ladle 32 into the melting furnace 2. The liquid level inside the melting furnace 2 is detected by the detection rod 35. After detecting the liquid level, the ladling robot 31 controls the ladle 32 to perform the ladling action;

[0092] After the ladling action, the ladling robot 31 controls the ladle 32 to perform the soup quantity quantification action;

[0093] After completing the soup volume quantification action, the pouring robot 31 controls the ladle 32 to inject the molten metal inside the ladle 32 into the barrel of the die-casting machine 1, and feeds back the injection signal to the die-casting machine 1 through the pouring robot 31;

[0094] After receiving the injection signal, the die-casting machine 1 performs the injection action. After the product is formed and the die-casting machine 1 opens the mold, the die-casting machine 1 feeds back the picking signal to the picking unit 4;

[0095] After receiving the picking signal, the picking unit 4 drives the picking mechanism 42 and the spraying mechanism 43 to move through the picking robot 41. While the picking mechanism 42 is moving, the demolding agent is sprayed onto the die-casting mold through the spraying mechanism 43, and the integrity of the product is detected by the detection support rod 46 provided on the picking unit 4;

[0096] The picking robot 41 drives the picking mechanism 42 to place the workpiece on the recycling and transportation line 5. The first conveyor belt 51 conveys the workpiece towards the blanking baffle 54, and cooling is performed by the cooling fan 53 on the first conveyor belt 51 of the recycling and transportation line 5;

[0097] After the workpiece reaches the blanking baffle 54, the head is removed manually, and the head is placed on the second conveyor belt 52 and re-injected into the first area 22 of the melting furnace 2 through the second conveyor belt 52;

[0098] The single handle put into the first area 22 of the melting furnace 2 is pressed down by the pressing mechanism 213, so that the single handle flows into the second area 23. The single handle melted by the melting furnace 2 in the second area 23 is pushed into the third area 24 by the pushing mechanism 214 for the ladle 32 to scoop up.

[0099] Scooping soup action. When scooping soup, the pouring robot 31 drives the ladle 32 to rotate, so that the inside of the ladle 32 is filled with molten metal.

[0100] Soup volume quantification action. First, scoop up the soup inside the ladle 32, and then drive the ladle 32 to rotate through the pouring robot 31 by setting the movement position of the point, pour out the excess soup volume, ensure that the soup volume is the same every time the same product is made, replace the situation where the soup scooping volume cannot be accurately controlled during manual material taking, improve the stability of the raw material volume during die-casting, and prevent overflow caused by too much soup volume or incomplete products caused by too little soup volume. When different products need to be replaced, change the soup volume poured out by changing the point posture to meet the production requirements of different products.

[0101] Among them, the point is the spatial position of each joint of the robotic arm. By calculating the spatial position of the robotic arm, the soup volume scooped out by the ladle 32 is ensured, and the final soup volume obtained each time of scooping soup is the same.

[0102] The injection action of the die-casting machine 1 is a conventional technology and will not be elaborated here.

[0103] When picking up the workpiece, the picking robot 41 of the picking part 4 drives the support plate 44 to move, making the support plate 44 approach the die part of the die-casting machine 1. The three-finger gripper 422 on the support plate 44 drives the clamping rod 421 to clamp the handle of the workpiece, and the picking robot 41 takes out the workpiece from the die of the die-casting machine 1. After the workpiece is separated from the die, the spraying mechanism 43 can be started to spray the release agent on the inner wall of the die, so as to facilitate the demoulding of the next workpiece and improve the efficiency of die-casting production.

[0104] And during the process of the picking robot 41 picking up the workpiece, the detection support rod 46 connected to the support plate 44 can abut against the outer wall of the workpiece. Since the detection support rod 46 is connected to an external relay, when both detection support rods 46 on the support plate 44 abut against the outer wall of the workpiece, if the workpiece is intact, the relay can be turned on at this time and a feedback signal can be given to the picking robot 41. If the workpiece is incomplete, the relay cannot be turned on, and the picking robot 41 cannot obtain a feedback signal at this time, indicating that there is a quality problem with the workpiece. The picking robot 41 can be controlled to place the problematic workpiece into a special waste recycling bin.

[0105] After the picking robot 41 takes out the workpiece from the die, the controller controls the pneumatic control valve to open. The water pump inputs the liquid into the liquid distribution pipe 436 of the first uniform plate 432 through the liquid joint 4321. The liquid is initially split through the first liquid distribution holes 437 and the second liquid distribution holes 438 on the liquid distribution pipe 436. Then the liquid enters the liquid distribution tank 435 of the first uniform plate 432. Subsequently, the air pump transports the gas into the liquid distribution tank 435 through the gas joint 4322. At this time, since the peripheral wall of the liquid distribution pipe 436 installed in the liquid distribution tank 435 is of an arc-shaped structure, the liquid can be further split to both sides, realizing the initial splitting of the gas, and the gas pushes the liquid to flow. The gas sprays the liquid onto the spiral splitting rod 430 inside the second uniform plate 433, and the second-step splitting is carried out through the spiral grooves 4301 opened on the spiral splitting rod 430. The liquid flows towards both ends of the spiral splitting rod 430 through the spiral grooves 4301 and enters the liquid guiding grooves 4341 of the connecting plate 434 under the action of the gas. Finally, it flows into each spray pipe 431 through the liquid guiding grooves 4341, realizing the third-step splitting, and finally obtaining a uniform and delicate spray, which can spray the spray evenly on the inner wall of the die during or after picking up the workpiece, so that the release agent can be evenly attached to the inner wall of the die.

[0106] It should be noted that before production, the amount of soup inside the ladle 32 needs to be determined according to the posture of the soup-feeding robot 31 to ensure that the amount of soup inside the ladle 32 is exactly adapted to the amount of soup required for die-casting workpieces each time, which can prevent the overflow of the soup amount and also ensure that the produced workpieces will not be defective.

[0107] After the picking robot 41 picks up the qualified workpieces, it places the workpieces on the recycling and transportation line 5, and transports the workpieces through the recycling and transportation line 5. The workpieces are conveyed to the blanking baffle 54 by the first conveyor belt 51. During the conveying process, they are cooled by the cold air fan 53. After the workpieces reach the blanking baffle 54, the material handles are removed manually to obtain the finished workpieces, and the waste material handles are placed on the second conveyor belt 52 through the blanking hole. The waste material handles are conveyed towards the melting furnace 2 by the second conveyor belt 52, and the waste material handles are put into the first area 22 of the melting furnace 2 by the discharge baffle 55 provided at the end of the second conveyor belt 52.

[0108] After entering the first area 22, the output end of the pressing mechanism 213 pushes the preliminarily melted waste blocks in the first area 22 downward. Since the depth of the filtering baffle 212 is greater than the depth of the blocking baffle 211, the waste blocks will flow to the second area 23. After the waste blocks flow to the second area 23, the output end of the pushing mechanism 214 pushes the waste blocks in the second area 23 to flow and flow into the third area 24 through the filtering holes 25 on the filtering baffle 212 for the soup part 3 to scoop up.

[0109] After being mixed in the melting furnace 2, it can be ensured that there is always a part of waste in the third area 24, and at the same time, the content of the waste will not be too much, which can save costs while ensuring a certain product quality.

[0110] Those skilled in the art can understand that other similar connection methods can also implement the present invention. For example, methods such as welding, bonding or screwing.

[0111] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
