Abstract
Description
Technical Field
[0001] This utility model belongs to the field of semiconductor manufacturing equipment technology, specifically relating to a loading and unloading device for cleaning DBC boards. Background Technology
[0002] During the production of DBC boards, the soldered substrates need to be cleaned to remove contaminants such as flux. During cleaning, a cleaning basket is generally used to hold the carrier, and then the carrier containing the DBC boards is placed into the cleaning basket for batch cleaning.
[0003] The patent specification with announcement number CN221754165U discloses a bipolar plate cleaning device for the hydrogen energy industry, including a cleaning basket, an ultrasonic cleaning workbench and a toothed plate above it. A first groove and a second groove are respectively opened on one side of the toothed plate. A slider is slidably connected to one side of the first groove. A cleaning basket is fixedly connected to one side of the slider. A cleaning basket translation mechanism is provided on one side of the slider to move the cleaning basket left and right along the toothed plate.
[0004] This type of cleaning equipment moves the cleaning basket horizontally by driving a first servo motor, and then drives a second servo motor to lower the cleaning basket connecting rod, immersing it in the cleaning tank mechanism for cleaning. After cleaning, the cleaning basket is lifted by driving a chain to detach it from the cleaning tank mechanism. The drawback of this technical solution is that the cleaning basket is empty before the substrate carrier is placed inside. During the entire operation of the equipment, the substrate carrier is always inside the cleaning basket. That is, it can only maintain automatic operation while the substrate carrier is in the cleaning basket. How the substrate carrier enters and leaves the cleaning basket is unknown. This results in a lack of automation in the loading and unloading process of the DBC substrate carrier with the cleaning basket, leading to a low degree of automation in the DBC board cleaning process.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0006] The purpose of this utility model is to provide a loading and unloading device for DBC board cleaning. The technical problem to be solved is as follows: the existing loading and unloading process of DBC boards with the cleaning basket before cleaning has a low degree of automation.
[0007] The objective of this utility model can be achieved through the following technical solutions:
[0008] A loading and unloading device for cleaning DBC boards includes a shifting module and a soldering and cleaning module. The shifting module includes a shifting frame, a lifting mechanism on one side of the bottom of the shifting frame, and multiple substrate carriers inserted into the lifting mechanism. A lifting belt is provided on one side of the lifting mechanism, and a shifting mechanism is installed on the top side of the shifting frame at the lifting belt. The shifting mechanism is used to shift the substrate carriers laterally and vertically. A rotating mechanism is provided on one side of the top of the shifting frame, which is used to rotate the substrate carriers by 90 degrees. The soldering and cleaning module is located on one side of the shifting module and, after processing the substrate carriers, returns the substrate carriers to the shifting module.
[0009] The process involves moving the lifting mechanism to a suitable position for transferring the substrate carrier at the shifting module, and then sequentially transferring the substrate carrier to the soldering and cleaning module by the shifting module and the rotating mechanism. After the substrate carrier is sequentially soldered with DBC boards and cleaned at the soldering and cleaning module, it is reset to the shifting module. Subsequently, the processed substrate carrier is returned to the lifting mechanism by the rotating mechanism and the shifting module. This process is repeated to achieve fully automated processing of the substrate carrier.
[0010] As a further embodiment of this utility model: the lifting mechanism includes a support plate, a cleaning basket is placed on the top of the support plate, and the base plate carrier is vertically inserted into the cleaning basket;
[0011] The lifting mechanism supports the cleaning basket via a support plate. A large number of substrate carriers to be processed are inserted into the cleaning basket. The grabbing of empty substrate carriers and the return of full-load substrate carriers are both located in the cleaning basket at the top of the support plate. After all the substrate carriers in the cleaning basket are in a full-load state, they can be lowered and reset to the conveying platform (not shown) by the lifting mechanism, thus completely completing the fully automatic soldering and cleaning process of the substrate carriers.
[0012] As a further embodiment of this utility model: the displacement mechanism includes a slide rail one installed on one side of the top of the displacement frame, a horizontal movement motor installed on one side of the slide rail one, a motor frame installed on one side of the top of the slide rail one, a vertical movement motor installed on the top of the motor frame, a clamping frame installed at the output end of the vertical movement motor, and an electric gripper installed at the bottom of the clamping frame.
[0013] The shifting mechanism first moves the substrate carrier vertically to a high position, and then moves it to the rotating mechanism by a horizontal motor, which facilitates the subsequent transfer and processing of the soldering and cleaning module.
[0014] As a further embodiment of this utility model: a vertical slide rail II is provided on one side of the motor frame, and the clamping frame is slidably connected to the slide rail II on one side;
[0015] That is, the vertical movement motor achieves vertical movement of the electric gripper through the guiding action of the slide rail two, and maintains the accuracy of the insertion and removal of the substrate carrier by means of the limiting action of the slide rail two.
[0016] As a further embodiment of this utility model: the rotating mechanism includes a carrier clamp disposed on one side of the top of the transfer frame, and a rotating motor is installed on one side of the carrier clamp;
[0017] That is, the substrate carrier is received by the vertical movement motor through the carrier clamp, and the substrate carrier is rotated to a horizontal state by the rotary motor, so that the soldering and cleaning module can grab it.
[0018] As a further embodiment of this utility model: the welding and cleaning module includes a gantry platform, a transverse frame is slidably connected between the two sides of the top of the gantry platform, a robotic arm is installed on one side of the transverse frame, a cleaning track is provided in the middle of the gantry platform, and a welding track is provided on the side of the gantry platform away from the transverse frame.
[0019] The welding and cleaning module uses a robotic arm to grab a horizontally placed substrate carrier and uses the movement of the gantry to sequentially place the substrate carrier into the welding track for welding and the cleaning track for cleaning. Then, the reverse operation is performed to reset the fully loaded substrate carrier to the rotation mechanism of the shift module. The shift module then moves in reverse to insert the substrate carrier back into the lifting mechanism, thus forming a fully automatic cycle processing function for the substrate carrier.
[0020] The beneficial effects of this utility model are:
[0021] By setting a shift module on one side of the welding and cleaning module, the lifting mechanism of the shift module raises the cleaning basket and the empty substrate carrier in the cleaning basket to the top of the shift frame. Then, the shift mechanism grabs and moves a single substrate carrier to the side close to the welding and cleaning module, and the rotating mechanism uses a horizontal mechanism to make the vertical substrate carrier horizontal, so that the robotic arm of the welding and cleaning module can grab it. After grabbing, the robotic arm, together with the gantry, moves the substrate carrier to the welding track for DBC substrate welding. Then, the fully loaded substrate carrier is moved to the cleaning track for cleaning. After processing, the substrate carrier is returned to the shift module, and then inserted back into the cleaning basket by the rotating mechanism and the shift mechanism in sequence. Its technical advantage is that by transferring and processing the single substrate carrier, the entire process of installing DBC substrates on the substrate carrier and cleaning it is automated, which effectively improves the efficiency of DBC substrate production.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0028] like Figures 1 to 3 As shown, a loading and unloading device for cleaning DBC boards includes a shifting module and a soldering and cleaning module. The shifting module includes a shifting frame 1, with a lifting mechanism 2 installed on one side of the bottom of the shifting frame 1. The lifting mechanism 2 includes multiple substrate carriers 23 inserted inside, and a support plate 21. A cleaning basket 22 is placed on the top of the support plate 21. The substrate carriers 23 are vertically and evenly inserted inside the cleaning basket 22. When the substrate carriers 23 are not in the soldering and cleaning module, they are in an unloaded state, that is, the DBC boards have not yet been soldered onto the substrate carriers 23. They need to be moved out of the cleaning basket 22 by the shifting module and transferred to the soldering and cleaning module for DBC cleaning. The BC substrate is soldered and cleaned, and then returned to the cleaning basket 22. A lifting belt 3 is provided on one side of the lifting mechanism 2. The lifting belt 3 is electrically driven to move the support plate 21 up to near the substrate carrier 23. A shifting frame 1 is equipped with a shifting mechanism 4 on one side of the top of the lifting belt 3. The shifting mechanism 4 is used to shift the substrate carrier 23 horizontally and vertically. A rotating mechanism 5 is provided on the side of the shifting frame 1 away from the lifting belt 3. The rotating mechanism 5 is used to rotate the substrate carrier 23 by 90 degrees. The soldering and cleaning module is located on one side of the shifting module, and after the substrate carrier 23 is processed, it returns the substrate carrier 23 to the shifting module.
[0029] like Figure 3As shown, the shifting mechanism 4 includes a slide rail 41 mounted on one side of the top of the shifting frame 1. A horizontal motor 42 is mounted on one side of the slide rail 41, a motor frame 43 is mounted on the top side of the slide rail 41, a vertical motor 44 is mounted on the top of the motor frame 43, a clamping frame 45 is mounted on the output end of the vertical motor 44, and an electric gripper 46 is mounted on the bottom of the clamping frame 45. After the lifting belt 3 lifts the cleaning basket 22 to the top of the shifting frame 1, the electric gripper 46 of the shifting mechanism 4 moves down along the slide rail 47 under the drive of the vertical motor 44 and clamps... The single substrate carrier 23 in the cleaning basket 22 is held, and the electric gripper 46 is moved upward to bring the substrate carrier 23 to a high position. Then, the horizontal motor 42 drives the motor frame 43 to move horizontally along the slide rail 41 to the side close to the welding cleaning module. This realizes the automatic separation function of the substrate carrier 23 to be welded DBC substrate from the cleaning basket 22. In addition, the electric gripper 46 can also be driven by a pneumatic structure. A vertical slide rail 47 is provided on one side of the motor frame 43, and the clamping frame 45 is slidably connected to the slide rail 47.
[0030] The rotating mechanism 5 includes a carrier clamp 51 located on one side of the top of the shifting frame 1. A rotary motor 52 is installed on one side of the carrier clamp 51. After the shifting mechanism 4 moves a single substrate carrier 23 to the rotating mechanism 5, the electric gripper 46 is driven down again by the vertical shifting motor 44 to insert the substrate carrier 23 into the carrier clamp 51. Then the rotary motor 52 rotates the substrate carrier 23 from a vertical state to a horizontal state, providing horizontal preparation for it to be received by the soldering cleaning module.
[0031] The welding and cleaning module includes a gantry platform 6, with a transverse frame 7 slidably connected between the two sides of the top of the gantry platform 6. A robotic arm 8 is mounted on one side of the transverse frame 7, and a drive belt for moving the robotic arm 8 is mounted on the back of the transverse frame 7 (see...). Figure 1A cleaning track 9 is set in the middle of the gantry platform 6, and a welding track 10 is set on the side of the gantry platform 6 away from the transverse frame 7. After the substrate carrier 23 is placed horizontally, the transverse frame 7 moves along the transverse frame 7 with the help of a transmission belt to the side close to the substrate carrier 23. The robotic arm 8 moves the unloaded substrate carrier 23 radially along the top of the gantry platform 6 to the welding track 10 for welding of the DBC substrates one by one. After welding is completed, it is moved to the cleaning track 9 in the middle of the gantry platform 6 for overall cleaning of the substrate carrier 23. That is, after a single substrate carrier 23 is transferred to the welding and cleaning module, it needs to undergo the following processes. After the DBC board is welded and the fully loaded substrate carrier 23 is cleaned and tidied, it is considered to be in a completed state. Then, the robotic arm 8 grabs the substrate carrier 23 and puts it back into the carrier clamp 51. After that, the rotary motor 52 rotates back to the starting direction, the shifting mechanism 4 grabs the fully loaded substrate carrier 23 and moves it upward. It returns to the initial position with the help of the slide rail 41. Then, the substrate carrier 23 is inserted back into the cleaning basket 22, and the welding and cleaning of the next single empty substrate carrier 23 is carried out. This realizes the fully automated processing of the substrate carrier 23 and improves the production efficiency of processing the substrate carrier 23.
