Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions of the embodiments of this disclosure, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] like Figures 1 to 13 As shown, this embodiment of the present disclosure provides a multi-station intelligent fully automatic low-pressure injection molding machine, including: a worktable 100, an annular guide rail 200 disposed on the worktable 100, a mold assembly 300 slidably disposed on the annular guide rail 200, and a feeding assembly 500, a mold closing assembly 800, an injection assembly 900, a heat dissipation assembly 1000, a mold opening assembly 1100, an ejection assembly 1200, a sprue assembly 1300, and a finished product removal assembly 1400 respectively disposed on the worktable 100 along the annular guide rail 200 and respectively corresponding to and cooperating with the mold assembly 300. The mold assembly 300 includes an upper mold 310 and a lower mold 320 respectively having an upper mold cavity and a lower mold cavity. This multi-station intelligent fully automatic low-pressure injection molding machine also includes a drive mechanism 400, which drives the mold assembly 300 sequentially through the feeding component 500, mold closing component 800, injection component 900, heat dissipation component 1000, mold opening component 1100, ejection component 1200, sprue component 1300, and finished product removal component 1400 to achieve automated and multi-station operation of product feeding, mold closing, injection, heat dissipation, mold opening, ejection, sprue removal, and finished product removal. The multi-station intelligent fully automatic low-pressure injection molding machine also includes a barcode scanning component 700 and a detection component; the barcode scanning component 700 is used for binding and inputting information about the mold assembly 300 and its internal products; the detection component 600 includes a feeding detection component 600 for detecting the product feeding status, a mold detection component for detecting mold cleanliness, and a finished product detection component 1800 for detecting finished product qualification.

[0024] This multi-station intelligent fully automatic low-pressure injection molding machine, according to an embodiment of the present disclosure, features a sliding mold assembly 300 mounted on a ring guide rail 200. Along the guide rail, functional components such as feeding, mold closing, injection molding, heat dissipation, mold opening, ejection, sprue, and finished product removal are integrated sequentially. This enables fully automated continuous production from product feeding to finished product removal. Furthermore, the injection molding machine integrates a barcode scanning component 700 for binding and inputting information about the mold assembly 300 and its internal products, as well as detection components for monitoring product feeding status, mold cleanliness, and finished product qualification. This injection molding machine allows for the breakdown of the injection molding process, reducing manual operation and improving work efficiency. Simultaneously, the feeding inspection, mold cleanliness inspection, and finished product inspection processes ensure correct product posture within the mold, absence of residual adhesive in the mold cavity, and detection of product appearance and dimensional defects, reducing product defects caused by human error and significantly improving product yield.

[0025] like Figure 2 As shown, the annular guide rail 200 includes an annular track 210 and a slide block 220 slidably disposed on the annular track 210. The slide block 220 is used to place the mold assembly 300. This annular guide rail 200 features automatic zeroing and high rigidity, enabling multi-station mold transfer. In this embodiment, a wheel set is provided at the bottom of the slide block 220, and the wheel set includes at least two rollers. During installation, the two rollers are respectively embedded on both sides of the annular track 210.

[0026] like Figure 3 As shown, the annular guide rail 200 also includes a first connector 230 disposed on the slide 220. The first connector 230 is used to connect the slide 220 to the drive mechanism 400. During use, the first connector 230 can drive the slide 220 to slide along the annular guide rail 200 under the action of the drive mechanism 400.

[0027] like Figure 3 As shown, the annular guide rail 200 also includes a positioning cylinder 240 fixed on the annular track 210 and a second connecting member 250 connected to the positioning cylinder 240 (the telescopic rod). The first connecting member 230 is provided with a first positioning mechanism 231, and the second connecting member 250 is provided with a second positioning mechanism 251 that cooperates with the first positioning mechanism 231. The positioning cylinder 240 is used to drive the second connecting member 250 to move along the Z-axis, so that the first positioning mechanism 231 and the second positioning mechanism 251 cooperate to achieve the positioning of the slide 220. This annular guide rail 200 has the characteristic of high repeatability positioning accuracy. In this embodiment, the first positioning mechanism 231 is a locking block provided on the first connecting member 230, and the second positioning mechanism 251 is a locking groove provided on the top of the second connecting member 250. During use, the positioning cylinder 240 can drive the second connecting member 250 to move upward, so that the second positioning mechanism 251 is nested in the first positioning mechanism 231 to achieve the positioning of the slide 220.

[0028] like Figure 3 As shown, the upper mold 310 and the lower mold 320 are placed side by side on the slide block 220. In this embodiment, the lower surface of the upper mold 310 is provided with an upper mold cavity, and the upper surface of the lower mold 320 is provided with a lower mold cavity. During use, the upper mold 310 does not need to be flipped. The mold closing assembly 800 and the mold opening assembly 1100 only need to perform simple clamping and XYZ axial movement to complete the mold closing and opening steps. At the same time, cleanliness testing can be completed without flipping.

[0029] like Figure 3 As shown, the upper mold 310 and lower mold 320 also have a positioning mechanism for positioning the upper mold 310 and lower mold 320. For example, the lower mold 320 has a set of positioning grooves 322 on one diagonal side and positioning pins 321 on the other diagonal side; the upper mold 310 has a set of pins corresponding to the positioning grooves 322 on one diagonal side and slots corresponding to the positioning pins 321 on the other diagonal side. During mold closing, the positioning pins 321 are inserted into the corresponding slots, and the positioning grooves 322 accommodate the corresponding pins, thereby achieving the positioning of the upper mold 310 and lower mold 320.

[0030] like Figure 3 As shown, the upper mold 310 also has a first through hole 311 distributed around the upper mold cavity for the mold opening assembly 1100 to pass through and press the lower mold 320. That is, after injection molding is completed, the mold opening assembly 1100 can pass through the first through hole 311 to press and fix the lower mold 320, so as to facilitate mold opening.

[0031] like Figure 3 As shown, the upper mold 310 also has an injection hole 312312 that communicates with the upper mold cavity and is used for injection of glue into the injection component 900. That is, during the injection molding process, the glue output by the injection component 900 enters the space between the upper mold cavity and the lower mold cavity through the injection hole 312312 to achieve injection molding.

[0032] like Figure 3 As shown, the lower mold 320 also has a second through hole 323 distributed around the lower mold cavity for the mold opening assembly 1100 to pass through and push the upper mold 310. That is, after injection molding, the mold opening assembly 1100 can pass through the second through hole 323 to push the upper mold 310, using the pushing force to separate the upper mold 310 from the lower mold 320, thereby realizing mold opening. Correspondingly, in order to facilitate the mold opening assembly 1100 to pass through the second through hole 323, the slide block 220 also has a through hole or opening corresponding to the second through hole 323.

[0033] like Figure 3As shown, the lower mold 320 also has a third through hole 324 communicating with the lower mold cavity and an ejector pin 325 disposed in the third through hole 324 for ejecting the finished product and sprue residue. That is, after the mold is opened, the ejector assembly 1200 can act on the ejector pin 325, causing the ejector pin 325 to move and eject the finished product and sprue residue from the lower mold cavity. Correspondingly, in order to facilitate the ejector assembly 1200 acting on the ejector pin 325, the slide block 220 also has a through hole or opening corresponding to the third through hole 324.

[0034] For example, the lower mold 320 also has a spring disposed between the ejector pin 325 and the lower mold 320 for resetting the ejector pin 325. That is, during the process of ejecting the finished product and sprue residue by the ejector pin 325, the spring can be stretched or compressed to accumulate potential energy. After the finished product and sprue residue are ejected, as the ejector assembly 1200 resets, the ejector pin 325 will also reset under the action of the spring's potential energy.

[0035] like Figure 2 As shown, the drive mechanism 400 includes a drive motor 404 and a transmission component 403 connected to the drive motor 404. The slide 220 is fixed to the transmission component 403 and slidably connected to the annular track 210. The drive motor 404 drives the transmission component 403 to move the slide 220 on the annular track 210. In this embodiment, the transmission component 403 is a transmission chain, which is mounted on the annular track 210 via a drive gear 401 and a driven gear 402. It is mounted on the back of the worktable 100, and its drive end passes through the worktable 100 and connects to the drive gear 401. During use, starting the drive motor 404 drives the transmission component 403 to run via the drive gear 401. During the operation of the transmission component 403, the slide 220 simultaneously slides on the annular track 210.

[0036] like Figure 2 As shown, the drive mechanism 400 also includes a reducer 405, whose input and output shafts are respectively connected to the drive end of the drive motor 404 and the drive gear 401. During use, the reducer 405 can reduce the speed and increase the output torque while transmitting power, so as to ensure the stable operation of the transmission component 403.

[0037] like Figure 4As shown, the loading assembly 500 includes a first linear motor 501, a second linear motor 502, a first electric cylinder 503, and a first vacuum suction cup 504. The first linear motor 501 is mounted on the worktable 100, the second linear motor 502 is mounted on the drive end of the first linear motor 501, the first electric cylinder 503 is mounted on the drive end of the second linear motor 502, and the first vacuum suction cup 504 is mounted on the drive end of the first electric cylinder 503. The first linear motor 501 drives the second linear motor 502 to move along the X-axis, the second linear motor 502 drives the first electric cylinder 503 to move along the Y-axis, and the first electric cylinder 503 drives the first vacuum suction cup 504 to move up and down along the Z-axis. The first vacuum suction cup 504 is used to pick up the product and transport it to the lower mold 320 (lower mold cavity) through three-axis movement. In specific implementations, the first vacuum suction cup 504 can be used with a vacuum generator to suction the product under negative pressure, and precise alignment of the product loading is achieved by the motion axis. In other words, the first linear motor 501, the second linear motor 502, and the first electric cylinder 503 constitute a three-axis manipulator, which can move the product adsorbed by the first vacuum suction cup 504 and transport it to the lower mold cavity of the lower mold 320.

[0038] like Figure 5 As shown, the loading detection component 600 includes a first CCD detection camera 601, which is disposed on the worktable 100. The first CCD detection camera 601 is used to acquire images of the product and determine whether the product's posture in the lower mold cavity meets the injection molding requirements based on the images. Specifically, the first CCD detection camera 601 can capture the posture and position of the product in the mold after loading, and determine whether "loading OK" or "loading NG", thus ensuring that the product's posture in the mold is correct. In this embodiment, the first CCD detection camera 601 is located above the movement trajectory of the mold assembly 300, and the first CCD detection camera 601 can capture images of the product passing below it.

[0039] like Figure 5As shown, the loading and detection assembly 600 also includes a product transfer assembly for removing products whose orientation does not meet the injection molding requirements from the lower mold cavity. The product transfer assembly includes a third linear motor 602, a fourth linear motor 603, a second electric cylinder 604, and a second vacuum chuck 605. The third linear motor 602 is mounted on the worktable 100, the fourth linear motor 603 is mounted on the drive end of the third linear motor 602, the second electric cylinder 604 is mounted on the drive end of the fourth linear motor 603, and the second vacuum chuck 605 is mounted on the drive end of the second electric cylinder 604. The third linear motor 602 drives the fourth linear motor 603 to move along the X-axis, the fourth linear motor 603 drives the second electric cylinder 604 to move along the Y-axis, and the second electric cylinder 604 drives the second vacuum chuck 605 to move up and down along the Z-axis. The second vacuum chuck 605 is used (in conjunction with a vacuum generator) to suction the product with negative pressure and remove the product from the lower mold cavity through three-axis movement. In other words, the third linear motor 602, the fourth linear motor 603, and the second electric cylinder 604 constitute a three-axis robotic arm. When the first CCD detection camera 601 determines that "feeding is not possible," the three-axis robotic arm can move the product adsorbed by the second vacuum suction cup 605 and remove it from the lower mold cavity into the recycling bin. It should be understood that once the product is removed, the mold assembly 300 is no longer ready for injection molding. The control center can control subsequent components to shield the mold assembly 300, and stop performing mold closing, injection molding, and other operations on the mold assembly 300.

[0040] Of course, in other embodiments, the second vacuum suction cup 605 can also be replaced by a robotic arm. When the position of the product in the lower mold cavity does not meet the injection molding requirements, the robotic arm can be used to adjust the position of the product to meet the injection molding requirements.

The mounting frame 701 is disposed on the workbench 100, and the barcode scanner 702 is disposed on the mounting frame 701. The barcode scanner 702 is used to scan the QR code information of the mold assembly 300 and the products, and to bind the QR code information of the mold assembly 300 and the products and then enter it into the MES system. In this embodiment, the barcode scanner 702 is located above the moving trajectory of the mold assembly 300, and the barcode scanner 702 can scan the QR codes of the mold assembly 300 and the products passing below it. In addition, there are three barcode scanners 702, one for scanning the QR code of the mold assembly 300, and the other two for scanning the QR codes of the two products respectively.

[0042] like Figure 7As shown, the mold clamping assembly 800 includes a first mold clamping electric cylinder 801, a second mold clamping electric cylinder 802, and a first gripper 803. The first mold clamping electric cylinder 801 is disposed on the worktable 100, the second mold clamping electric cylinder is disposed on the telescopic rod of the first mold clamping electric cylinder, and the first gripper 803 is disposed on the telescopic rod of the second mold clamping electric cylinder.

The first gripper 803 is used to grip the upper mold 310 and transport the upper mold 310 to the lower mold 320 through the two-axis movement. That is to say, the first mold clamping electric cylinder 801 and the second mold clamping electric cylinder 802 constitute a two-axis manipulator. This two-axis manipulator can move the upper mold 310 gripped by the first gripper 803 to transport it to the lower mold 320 to achieve mold clamping. In this embodiment, the first gripper 803 includes a contour gripper and a gripper cylinder for driving the contour gripper to open and close. The first mold closing electric cylinder 801 and the second mold closing electric cylinder 802 are linear lead screw modules in which a servo motor drives the lead screw to move through a coupling.

[0043] like Figure 8 As shown, the injection molding assembly 900 includes a first injection cylinder 901, a pressure plate 902, a second injection cylinder 903, a glue gun 904, and a glue supply unit 905.

The nozzle is connected to the glue inlet of the glue gun 904; the first injection cylinder 901 is used to drive the pressure plate 902 to move up and down along the Z-axis to press the upper mold 310 so that it fits tightly with the lower mold 320; the second injection cylinder 903 is used to drive the glue gun 904 to move up and down along the Z-axis so that the nozzle of the glue gun 904 aligns with the glue injection hole 312; the glue supply unit 905 is used to supply glue to the glue gun 904 so that the glue gun 904 injects glue into the glue injection hole 312. In other words, during the injection molding process, the first injection cylinder 901 is controlled to drive the pressure plate 902 to move down and press the upper mold 310 to fit tightly against the lower mold 320. Then, the second injection cylinder 903 is controlled to drive the injection gun 904 to move down so that its nozzle aligns with the injection hole 312 of the upper mold 310. Finally, the glue supply unit 905 is controlled to supply glue to the injection gun 904, thereby realizing glue injection between the upper mold 310 and the lower mold 320 through the injection hole 312. In this embodiment, the glue supply unit 905 includes a melting cylinder for melting plastic into liquid glue, a gear pump located at the outlet of the melting cylinder for metering and stabilizing the liquid glue output from the melting cylinder, and a glue delivery tube connected between the outlet of the gear pump and the inlet of the injection gun 904 for conveying the liquid glue to the injection gun 904. It should be noted that the injection molding assembly 900 as a whole can realize a fully automated process including intelligent temperature control, mold closing, glue injection, and pressure holding.

[0044] For example, the injection molding assembly 900 also includes a first guide rod 906, which is disposed on the worktable 100 and extends along the Z-axis. The pressure plate 902 is slidably disposed on the first guide rod 906. During use, the first guide rod 906 can guide the pressure plate 902 to make the operation of the pressure plate 902 more stable and reliable.

[0045] For example, the injection molding assembly 900 further includes a second guide rod 907, a first movable plate 908, and a second movable plate 909. The second guide rod 907 is disposed on the pressure plate 902. The first movable plate 908 is disposed at the top of the second guide rod 907 and connected to the drive end of the first injection cylinder 901. The second movable plate 909 is slidably disposed on the second guide rod 907 and connected between the drive end of the second injection cylinder 903 and the dispensing gun 904. That is, the pressure plate 902 is disposed at the drive end of the first injection cylinder 901 via the second guide rod 907 and the first movable plate 908, and the dispensing gun 904 is disposed at the drive end of the second injection cylinder 903 via the second movable plate 909. Furthermore, during the movement of the dispensing gun 904, the second movable plate 909 and the second guide rod 907 can cooperate to guide the dispensing gun 904.

[0046] like Figure 9 As shown, the heat dissipation assembly 1000 includes a spray head 1001, which is disposed on the worktable 100. The spray head 1001 has at least one spray hole for connecting to an external air source and spraying a cooling medium (such as compressed air) onto the upper mold 310. That is, during use, the control center can control the external air source to deliver a cooling medium to the spray head 1001, which is then sprayed onto the upper mold 310 through the spray hole of the spray head 1001 to cool the mold assembly 300 and the product. In this embodiment, the spray head 1001 is located above the moving trajectory of the mold assembly 300, enabling it to cool the mold assembly 300 passing below it. Furthermore, there are four spray holes arranged in an array.

[0047] like Figure 1 As shown, there are multiple spray heads 1001, which are spaced apart along the conveying direction of the annular track 210. In this embodiment, there are three spray heads 1001, and the three heat dissipation components 1000 can sequentially cool the mold assembly 300.

[0048] like Figure 9As shown, the heat dissipation assembly 1000 also includes at least one connector 1002 for connecting the injection hole to an external air source. In this embodiment, there are four connectors 1002, each connected to the air inlet of a corresponding injection hole. During installation, the connectors 1002 can be connected to an external air source via air pipes, and these air pipes can be equipped with solenoid valves for controlling airflow. After the injection molding process is completed, the solenoid valves can be triggered to use compressed air to cool the mold.

[0049] like Figure 9 As shown, the heat dissipation assembly 1000 also includes a temperature measuring device 1003 (such as an infrared thermometer). The temperature measuring device 1003 is disposed on the spray head 1001 and is used to detect the temperature of the upper mold 310. In this embodiment, the temperature measuring device 1003 is only disposed on the spray head 1001 closest to the mold opening assembly 1100 to detect and record the temperature of the upper mold 310 before mold opening. During use, the control center can determine whether to continue controlling the external air source to output cooling medium based on the temperature detected by the temperature measuring device 1003. At the same time, it can also control the output pressure and flow rate of the external air source to ensure that the temperature of the mold assembly 300 and the product can meet the mold opening requirements.

[0050] like Figure 10As shown, the mold opening assembly 1100 includes a first mold opening electric cylinder 1101, a second mold opening electric cylinder 1102, a third mold opening electric cylinder 1103, a first mounting plate 1104, a second mounting plate 1105, a first ejector pin 1106, a second ejector pin 1107, and a second gripper 1108. The first mold opening electric cylinder 1101 is disposed on the worktable 100, the second mold opening electric cylinder 1102 is disposed on the drive end of the second mold opening electric cylinder 1102, the third mold opening electric cylinder 1103 is disposed on the worktable 100, the first mounting plate 1104 is disposed on the drive end of the second mold opening electric cylinder 1102 and is located above the mold assembly 300, the first ejector pin 1106 and the second gripper 1108 are disposed on the lower surface of the first mounting plate 1104, and the second mounting plate 1105 is disposed on the lower surface of the third mold opening electric cylinder 1106. The driving end of the mold cylinder 1103 is located below the mold assembly 300, and the second ejector rod 1107 is disposed on the upper surface of the second mounting plate 1105. The first mold opening cylinder 1101 is used to drive the second mold opening cylinder 1102 to move along the Y-axis, and the second mold opening cylinder 1102 is used to drive the first mounting plate 1104 to rise and fall along the Z-axis so that the first ejector rod 1106 passes through the first through hole 311 to press the lower mold 320. The third mold opening cylinder 1103 is used to drive the second mounting plate 1105 to rise and fall along the Z-axis so that the second ejector rod 1107 passes through the second through hole 323 to push the upper mold 310 to separate it from the lower mold 320. The second gripper 1108 is used to grip the separated upper mold 310 and move the upper mold 310 back to the slide block 220 by moving the two axes. In other words, during use, the second mold-opening electric cylinder 1102 is first controlled to move the first push rod 1106 downwards to press down the lower mold 320. Then, the third mold-opening electric cylinder 1103 is controlled to move the first push rod 1106 upwards to push up the upper mold 310, thereby separating the upper mold 310 from the lower mold 320 under the pushing force. Subsequently, the second gripper 1108 can be controlled to grip the separated upper mold 310, and then, in conjunction with the two-axis movement of the first mold-opening electric cylinder 1101 and the second mold-opening electric cylinder 1102, the upper mold 310 is moved back to the slide block 220. In this embodiment, the second gripper 1108 includes a contour gripper and a gripper cylinder that drives the contour gripper to open and close.

[0051] For example, the third mold-opening electric cylinder 1103 is disposed on the lower surface of the worktable 100, and the drive end of the third mold-opening electric cylinder 1103 passes through the worktable 100 and is connected to the second mounting plate 1105.

[0052] like Figure 10As shown, the mold inspection assembly includes an upper mold cleanliness inspection assembly 1500 for inspecting the cleanliness of the upper mold 310 after mold opening. The upper mold cleanliness inspection assembly 1500 includes a second CCD inspection camera, which is disposed on the worktable 100. The second CCD inspection camera is used to acquire images of the lower surface of the upper mold 310 and determine whether the upper mold 310 meets the cleanliness requirements based on the images. In this embodiment, the second CCD inspection camera is installed on one side of the annular track 210 and located below the mold assembly 300, and it can capture images of the upper mold 310 passing above it. For example, during the process of the mold opening assembly 1100 transporting the upper mold 310, the first mold opening electric cylinder 1101 can first move the upper mold 310 to a position above the second CCD inspection camera to perform upper mold 310 cleanliness inspection, and then place the upper mold 310 in the parking position.

[0053] like Figure 11 As shown, the ejection assembly 1200 includes a first ejection electric cylinder 1201, a second ejection electric cylinder 1202, a third mounting plate 1203, a fourth mounting plate 1204, a third ejector rod 1205, and a fourth ejector rod 1206. The first ejection electric cylinder 1201 is mounted on the worktable 100, the second ejection electric cylinder 1202 is mounted on the worktable 100, the third mounting plate 1203 is mounted on the drive end of the first ejection electric cylinder 1201 and located above the mold assembly 300, and the third ejector rod 1205 is mounted on the third mounting plate 1203 (see table below). The fourth mounting plate 1204 is located at the drive end of the second ejector cylinder 1202 and below the mold assembly 300. The fourth ejector rod 1206 is located on the upper surface of the fourth mounting plate 1204. The first ejector cylinder 1201 drives the third mounting plate 1203 to move up and down along the Z-axis, so that the third ejector rod 1205 presses down the mold 320. The second ejector cylinder 1202 drives the fourth mounting plate 1204 to move up and down along the Z-axis, so that the fourth ejector rod 1206 pushes the ejector pin 325 to eject the finished product and sprue residue. In other words, during use, the ejector assembly 1200 can use the upper and lower cylinders in conjunction with the ejector rod to make the ejector pin 325 inside the mold eject upward to eject the product and sprue residue. Specifically, first, control the first ejector cylinder 1201 to move the third ejector rod 1205 to lower and press down the mold 320, then control the second ejector cylinder 1202 to move the fourth ejector rod 1206 to move up and push the ejector pin 325 so that the ejector pin 325 ejects the finished product and the remaining material from the sprue.

[0054] For example, the second ejector cylinder 1202 is disposed on the lower surface of the worktable 100, and the drive end of the second ejector cylinder 1202 passes through the worktable 100 and is connected to the fourth mounting plate 1204.

[0055] like Figure 12As shown, the water intake assembly 1300 includes a third electric cylinder 1301, a fourth electric cylinder 1302, and a third gripper 1303. The third electric cylinder 1301 is mounted on the worktable 100, the fourth electric cylinder 1302 is mounted on the drive end of the third electric cylinder 1301, and the third gripper 1303 is mounted on the drive end of the fourth electric cylinder 1302. The third electric cylinder 1301 drives the fourth electric cylinder 1302 to move along the Y-axis, and the fourth electric cylinder 1302 drives the third gripper 1303 to move up and down along the Z-axis. The third gripper 1303 is used to grip the waste material from the water intake and remove it through the movement of the two axes. In other words, the water intake assembly 1300 can move in coordination with the third electric cylinder 1301 and the fourth electric cylinder 1302, and with the third gripper 1303, grip the waste material from the water intake and throw it into the waste bin. Specifically, the third electric cylinder 1301 and the fourth electric cylinder 1302 constitute a two-axis manipulator. This two-axis manipulator can move the third gripper 1303 to pick up the sprue residue and remove it from the lower mold 320, sending it into the waste bin. In this embodiment, the third gripper 1303 includes a contour gripper and a gripper cylinder that drives the contour gripper to open and close.

[0056] like Figure 12 As shown, the mold detection assembly also includes a sprue detection assembly 1600 for detecting residual sprue material. The sprue detection assembly 1600 includes a third CCD detection camera, which is mounted on the worktable 100. The third CCD detection camera is used to acquire images of the lower mold 320 and determine whether residual sprue material still exists in the lower mold cavity based on the images. This allows the sprue removal assembly 1300 to determine whether to end the sprue removal operation based on the detection results of the sprue detection assembly, ensuring that there is no residual sprue material in the cavity of the lower mold 320. In this embodiment, the third CCD detection camera is installed on the drive end of the third electric cylinder 1301 and can move along the Y-axis with the third gripper 1303. After the third gripper 1303 removes the residual sprue material, the third CCD detection camera can detect whether residual sprue material still exists in the lower mold cavity of the lower mold 320. If residual sprue material still exists, the control center can control the sprue removal assembly 1300 to repeat the sprue removal operation until the residual sprue material is completely removed.

In other words, after the third vacuum suction cup 1404 picks up the finished product from the lower mold 320, it can cooperate with the two-axis movement of the fifth linear motor 1401 and the fifth electric cylinder 1402 to transport the picked-up product to the transfer table 1406. Then, the fourth CCD inspection camera is used to detect whether the finished product on the transfer table 1406 is a good product. If the finished product is a good product, the fourth vacuum suction cup 1405 can pick up the finished product on the transfer table 1406 and cooperate with the two-axis movement of the fifth linear motor 1401 and the sixth electric cylinder 1403 to transport the picked-up finished product to the good product area. Otherwise, the fourth vacuum suction cup 1405 can pick up the finished product on the transfer table 1406 and cooperate with the two-axis movement of the fifth linear motor 1401 and the sixth electric cylinder 1403 to transport the picked-up finished product to the defective product area. In this embodiment, the fourth CCD inspection camera is mounted on the fifth linear motor 1401 and can follow the fourth vacuum suction cup 1405 to move along the X-axis. The fourth CCD inspection camera can use AOI visual inspection software and monitoring training software, based on a workflow inspection function that combines deep learning and traditional visual algorithms, to perform fully automatic inspections of finished products, such as appearance inspection and size inspection.

[0058] like Figure 13As shown, the mold inspection assembly also includes a lower mold cleanliness inspection assembly 1700 for inspecting the cleanliness of the lower mold 320 after the finished product is removed. The lower mold cleanliness inspection assembly 1700 includes a fifth CCD inspection camera, which is set on the worktable 100. The fifth CCD inspection camera is used to acquire images of the lower mold 320 and determine whether there is any waste material residue in the lower mold cavity based on the images. In this embodiment, the fifth CCD inspection camera is mounted on a fifth linear motor 1401 and can move along the X-axis following the third vacuum suction cup 1404. The fifth CCD inspection camera can take images of the lower mold 320 after the finished product is removed by the third vacuum suction cup 1404.
