[0046] As shown in Figure 1 The transfer device includes a full-automatic truss and a transfer robot 500 mounted on the full-automatic truss, and the full-automatic truss is erected above the feeding conveying device 100, the discharging conveying device 200, the cleaning device, the draining mechanism and the drying mechanism.

[0047] As shown in Figure 1 The present application provides a first embodiment of the layout of the silicon rod cleaning equipment. The full-automatic truss is composed of a first truss 300 and a second truss 400, and both the first truss 300 and the second truss 400 are provided with a transfer robot 500. Among them, the first truss 300 and the second truss 400 are arranged side by side along the conveying direction of the workpiece. In addition, the feeding conveying device 100 and the discharging conveying device 200 are located on the same side of the cleaning device, and the feeding conveying device 100 and the discharging conveying device 200 are arranged side by side in a direction away from the cleaning device, so that the feeding conveying device 100, the discharging conveying device 200, the cleaning module 1, the first truss 300 and the second truss 400 jointly form a double-station cleaning silicon rod, further improving the production efficiency.

[0048] It can be understood that the working principles of the first truss 300 and the second truss 400 are the same, that is, the equipment of the present application provides two stations to realize the cleaning of the silicon rod. Of course, in actual application, the number of trusses and cleaning modules can be increased or decreased according to actual conditions to meet the actual production needs.

[0049] As Figure 2 shown, the application also provides other embodiments about the layout of the silicon rod cleaning device.

[0050] Specifically, the full-automatic gantry is composed of a first gantry 300 and a second gantry 400, and both the first gantry 300 and the second gantry 400 are provided with a transfer manipulator 500. Among them, the first gantry 300 and the second gantry 400 are arranged side by side along the conveying direction of the workpiece. In addition, the feeding conveying device 100 and the discharging conveying device 200 are located on the same side of the cleaning device, and the feeding conveying device 100 and the discharging conveying device 200 are arranged side by side in a direction away from the cleaning device, so that the feeding conveying device 100, the discharging conveying device 200, the cleaning module 1, the first gantry 300 and the second gantry 400 jointly form a U-shaped conveying line.

[0051] It can be understood that the feeding conveying device 100 conveys the silicon rod to be cleaned to the feeding end of the first gantry 300, the transfer manipulator 500 on the first gantry 300 clamps the silicon rod to be cleaned and transfers it into the cleaning device, after the silicon rod is cleaned in the cleaning device, the transfer manipulator 500 on the first gantry 300 or the manipulator on the second gantry 400 can take out the silicon rod which has been cleaned from the cleaning device and transfer it to the draining mechanism and the drying mechanism to sequentially complete the surface draining and drying. Finally, the transfer manipulator 500 on the first gantry 300 can transfer the silicon rod to the discharging end of the drying mechanism, so that the manipulator on the second gantry 400 clamps and transfers the silicon rod to the feeding end of the discharging conveying device 200 to send out, and the transfer manipulator 500 on the first gantry 300 resets to the discharging end of the feeding conveying device 100 after completing the discharging to transfer the next silicon rod to be cleaned;

[0052] Or, the manipulator on the second gantry 400 can directly take out the silicon rod from the drying mechanism and clamp and transfer it to the feeding end of the discharging conveying device 200 to send out.

[0053] Preferably, the application preferably uses the first gantry 300 only for the transfer of the silicon rod between the feeding conveying device 100 and the cleaning device, and the transfer between the cleaning device and the discharging conveying device 200 is realized by the second gantry 400. Since the silicon rod clamped by the transfer manipulator 500 of the first gantry 300 is not cleaned, it avoids the influence of the impurities remaining on the transfer manipulator 500 of the first gantry 300 on the surface quality of the silicon rod which has completed cleaning and drying.

[0054] And by arranging the feeding conveying device 100, the discharging conveying device 200, the cleaning module 1, the first gantry 300 and the second gantry 400 as a U-shaped conveying line, not only the conveying path of the silicon rod is optimized, but also the equipment is more compact, and the space occupancy rate of the equipment is reduced.

[0055] Optionally, the ultrasonic cleaning machine is preferred as the cleaning device of the present application. Further, a temperature-adjustable heating mechanism can be added in the cleaning tank of the ultrasonic cleaning machine to improve the cleaning effect of the silicon rod.

[0056] According to some embodiments of the present application, the draining mechanism comprises an air pipe 700 connected to an external air blower through a pipe. Further, as shown in Figure 3 The air pipe 700 is provided with a strip-shaped air outlet 710, and the air pipe 700 can output air flow in the form of a sheet to better remove the liquid on the surface of the silicon rod. By blowing away the surface liquid with dry air, the surface of the silicon rod can be prevented from being scratched, which helps to ensure the product quality of the silicon rod.

[0057] Optionally, two air pipes 700 can be arranged on both sides of the silicon rod, and the air outlets 710 of the two air pipes 700 can jointly deliver dry air to the silicon rod from two directions, effectively improving the drying efficiency.

[0058] Further, the air flow output by the air pipe 700 can form a certain angle with the surface of the silicon rod. It can be understood that the air pipe 700 delivers air flow obliquely downward to the silicon rod to better carry away the liquid on the surface of the silicon rod and reduce residue.

[0059] Optionally, a heating element can be added to the air pipe 700, so that the air pipe 700 can output hot air to improve the drying efficiency of the silicon rod.

[0060] According to some embodiments of the present application, as shown in Figure 4 and Figure 5 The transfer manipulator 500 comprises a fixed base 510, a left jaw assembly, and a right jaw assembly. The left and right jaw assemblies are movably connected to the fixed base 510, and the left and right jaw assemblies are oppositely arranged to form a clamping cavity for accommodating the silicon rod.

[0061] One of the left and right jaw assemblies can be fixed to the fixed base 510, and the other can move on the fixed base 510. By adjusting the position of the left or right jaw assembly on the fixed base 510, the opening and closing of the transfer manipulator 500 can be realized.

[0062] Or,

[0063] Both the left and right jaw assemblies can move on the fixed base 510. That is, the left and right jaw assemblies can move closer to or away from each other to realize the opening and closing of the transfer manipulator 500.

[0064] Specifically, the fixed base 510 is provided with an opening and closing driving module 600 for driving the transfer manipulator 500.

[0065] The driving module 600 is composed of a driving member 610 and a screw rod assembly 620. The screw rod assembly 620 is connected with the output end of the driving member 610. The transfer robot 500 is rotatably connected with the screw rod assembly 620. The driving member 610 can drive the screw rod assembly 620 to rotate reversely to realize the opening and closing of the transfer robot 500.

[0066] Optionally, as the first embodiment described above, one of the left jaw assembly and the right jaw assembly is fixed on the fixed base 510, and the other is movable on the fixed base 510.

[0067] Specifically, the left jaw assembly is rotatably connected with the screw rod assembly 620. When the driving member 610 drives the screw rod assembly 620 to rotate reversely, the left jaw assembly can be away from or close to the right jaw assembly, so as to realize the opening and closing of the transfer robot 500.

[0068] Optionally, as the second embodiment described above, the left jaw assembly and the right jaw assembly are both movable on the fixed base 510.

[0069] Specifically, the screw rod assembly 620 includes a first transmission rod 621 and a second transmission rod 622. The left jaw assembly is rotatably connected with the first transmission rod 621, and the right jaw assembly is rotatably connected with the second transmission rod 622.

[0070] It should be noted that the thread rotation direction of the first transmission rod 621 is opposite to that of the second transmission rod 622.

[0071] Optionally, the first transmission rod 621 and the second transmission rod 622 are in a split structure, and one driving member 610 is separately arranged corresponding to the first transmission rod 621 and the second transmission rod 622.

[0072] Preferably, the first transmission rod 621 and the second transmission rod 622 in the present application are in an integrated structure, and one driving member 610 is connected with one of the first transmission rod 621 and the second transmission rod 622. The synchronous rotation of the first transmission rod 621 and the second transmission rod 622 can ensure the stability of the opening and closing of the transfer robot 500, and can reduce the cost of the equipment.

[0073] Further, the fixed base 510 is provided with a guide assembly. As shown in the figure, the guide assembly includes a guide rail 630 fixed on the fixed base 510 and a sliding block 640 slidingly installed on the guide rail 630.

[0074] Optionally, the left jaw assembly and the right jaw assembly are connected with the sliding block 640 at the end close to the fixed base 510.

[0075] It can be understood that the left clamping jaw assembly, the right clamping jaw assembly and the screw rod assembly 620 are rotatably connected, and the left clamping jaw assembly, the right clamping jaw assembly and the sliding block 640 are fixedly connected. When the screw rod assembly 620 rotates to move the left clamping jaw assembly and the right clamping jaw assembly, the left clamping jaw assembly and the right clamping jaw assembly can pull or push the sliding block 640 to slide on the guide rail 630.

[0076] Through the cooperation of the guide rail 630 and the sliding block 640, on the one hand, the guide rail 630 and the sliding block 640 can bear the weight of the left clamping jaw assembly and the right clamping jaw assembly of the screw rod assembly 620, which helps to prolong the service life of the screw rod assembly 620, and on the other hand, it can ensure the straight-line movement of the left clamping jaw assembly and the right clamping jaw assembly to be accurate, thereby ensuring the stable clamping of the transfer robot 500 to the silicon rod.

[0077] According to some embodiments of the present application, as shown in the drawings, the left clamping jaw assembly and the right clamping jaw assembly each consist of a connecting seat 520 and a clamping block 530 arranged on the connecting seat 520. The connecting seat 520 is rotatably connected with the screw rod assembly 620, and is also fixedly connected with the sliding block 640.

[0078] Specifically, the side of the clamping block 530 facing the clamping cavity is provided with a buffer assembly, which includes a buffer spring 531 and a buffer plate 532. One end of the buffer spring 531 is fixed to the connecting seat 520, and the buffer plate 532 is installed on the other end of the buffer spring 531. The buffer plate 532 is arranged on the same side as the clamping cavity.

[0079] As a further optimization of the scheme of the present application, the side of the buffer plate 532 close to the clamping cavity is also provided with a buffer pad 533.

[0080] By using the buffer spring 531 in combination with the buffer pad 533, the silicon rod can be effectively protected, and the surface of the silicon rod can be prevented from being damaged due to rigid contact with the clamping block 530, thereby reducing the production scrap rate.

[0081] Further, the buffer pad 533 can also be provided with a protruding part 5331 for increasing friction. Preferably, the protruding part 5331 of the present application is designed as a strip-shaped protrusion.

[0082] According to some embodiments of the present application, the transfer robot 500 is also provided with a plurality of sensors.

[0083] Specifically, the left clamping jaw assembly and the right clamping jaw assembly are each provided with a pressure sensor, and the pressure sensor is electrically connected with the control module of the device. Through the system preset pressure value, when the pressure sensor on the left clamping jaw assembly and the right clamping jaw assembly detects that the clamping pressure reaches the preset value during clamping of the silicon rod, the driving part 610 stops after receiving the system signal, thereby avoiding excessive clamping of the silicon rod by the transfer robot 500 and causing damage to the surface of the silicon rod.

[0084] Furthermore, a first photoelectric sensor is provided on one side of the clamping cavity or inside the clamping cavity to detect whether there is a silicon rod in the clamping cavity of the transfer robot 500, so as to avoid repeated clamping by the transfer robot 500, which could cause the silicon rod to stack in the clamping cavity, resulting in the silicon rod colliding and being scrapped.

[0085] Furthermore, a second photoelectric sensor is installed on one side of the clamping cavity or inside the clamping cavity. The second photoelectric sensor is mainly used to monitor whether the silicon rod falls off during the transfer process by the transfer robot 500.

[0086] Furthermore, such as Figure 6 As shown, both the first truss 300 and the second truss 400 are equipped with a floating mechanism 800. Specifically, the floating mechanism 800 includes a floating seat 810 mounted on the truss and a floating rod 820 slidably connected to the floating seat 810. One end of the floating rod 820 is connected to the transfer robot 500. A proximity switch 830 is provided on the floating seat 810 or the floating rod 820, wherein the proximity switch 830 is used to monitor whether the floating rod 820 has moved.

[0087] Understandably, if the first photoelectric sensor malfunctions during material handling by the transfer robot 500, causing it to continuously descend, the continuing descent of the robot to a certain height can cause the floating rod 820 to move. Once the proximity switch 830 detects this displacement, it immediately sends a signal to the equipment's control module. The control module then sends a command to the transfer robot 500, which immediately stops descending and begins to slowly rise, resetting to a safe position. This closed-loop control system, formed by the floating mechanism 800 and the second photoelectric sensor, prevents the transfer robot 500 from colliding with the silicon rod and causing damage.

[0088] This application uses a feeding conveyor 100 to automatically feed silicon rods into the equipment. A transfer device is responsible for transferring the silicon rods from the feeding conveyor 100 to the cleaning module 1. After the silicon rods have flowed between the cleaning device, the draining mechanism, and the drying mechanism, that is, after the silicon rods have been cleaned, drained, and dried in sequence, the transfer device transfers the silicon rods from the drying mechanism to the unloading conveyor 200. The unloading conveyor 200 sends the silicon rods out of the equipment, completing the entire cleaning process.

[0089] The whole process, the silicon rod is from loading, unloading and surface drying automatic processing, greatly improves the production efficiency and production automation degree. At the same time, for the surface liquid cleaning of the silicon rod after finishing cleaning, it is not necessary to rely on manual wiping of workers. Before the silicon rod enters the drying mechanism, the application removes the liquid on the surface of the silicon rod by setting the draining mechanism, so that the silicon rod can reduce the residual traces of water stains on the surface of the silicon rod after drying, effectively reducing the labor intensity of workers and the personnel cost of enterprises, and also can avoid scratching the surface of the silicon rod when wiping, effectively ensuring the surface quality of the silicon rod and reducing the production loss.
