Detailed Implementation

[0018] 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 protection scope of the present utility model.

[0019] An embodiment provides a ceramic circuit board loading device, such as Figures 1-5 As shown, the device includes a base frame 1, a rotatable turntable 2 on one side of the top of the base frame 1, and a transfer mechanism 3 on the other side of the top of the base frame 1. The transfer mechanism 3 includes a slide table 31, which can move horizontally toward or away from the turntable 2. The turntable 2 is circumferentially provided with four material racks 4, each of which includes two vertically arranged belt assemblies 5. Multiple support bars 6 are distributed along the length of the flat belt of the belt assembly 5. The support bars 6 are used to horizontally support the ceramic circuit boards. A transmission assembly 7 is provided on the side of the material rack 4 near the center of the turntable 2. The transmission assembly 7 is used to convert the movement of the slide table 31 away from the turntable 2 into the operation of the flat belt of the belt assembly 5, thereby causing the support bars 6 and the ceramic circuit boards supported on them to move up for the transfer mechanism 3 to pick up.

[0020] In this embodiment, the transfer mechanism 3 further includes a gantry 32, an electric slide rail 33, a telescopic drive 34, and a suction assembly 35. The gantry 32 is fixed to the top of the base frame 1. An electric slide rail 33 is installed on the top of the gantry 32. A slide table 31 is connected to the output end of the electric slide rail 33. A telescopic drive 34 is installed on the bottom of the slide table 31. The suction assembly 35 is connected to the output end of the telescopic drive 34.

[0021] In this embodiment, the transmission assembly 7 includes a transmission gear 71, a second belt assembly 72, a worm gear 73, a worm 74, and a linkage mechanism 75. Two meshing transmission gears 71 are rotatably connected to the material preparation rack 4. A second belt assembly 72 is provided between each transmission gear 71 and the adjacent first belt assembly 5. One pulley of the second belt assembly 72 is coaxially arranged with the pulley of the first belt assembly 5, and the other pulley of the second belt assembly 72 is coaxially arranged with the transmission gear 71. One of the transmission gears 71 is coaxially arranged with the worm gear 73. A worm 74 is rotatably connected to the material preparation rack 4, and the worm 74 meshes with the worm gear 73. A linkage mechanism 75 is provided on the material preparation rack 4 for cooperating with the slide table 31 to drive the worm 74 to rotate.

[0022] The linkage mechanism 75 includes a ratchet 751, a ratchet rack 752, a stop plate 753, and a push plate 754. The ratchet 751 is coaxially mounted on the worm gear 74. The stop plate 753 is slidably connected to the material rack 4. The ratchet rack 752 is elastically connected to the stop plate 753, and the stop plate 753 is connected to the material rack 4 by an elastic element 755. The ratchet rack 752 matches the tooth profile of the ratchet 751, and can drive the ratchet 751 to rotate only when the ratchet rack 752 moves toward the transfer mechanism 3. The push plate 754 is fixedly connected to the slide table 31 near the turntable 2. The push plate 754 is used to abut against the stop plate 753.

[0023] In this embodiment, the suction assembly 35 includes a fixed plate 351 and suction nozzles 352. The fixed plate 351 is fixed to the output end of the telescopic drive member 34, and four suction nozzles 352 are connected to the bottom of the fixed plate 351 for suctioning ceramic circuit boards.

[0024] In this embodiment, in order to drive the turntable 2 to rotate, a drive motor 21 is installed on the base frame 1, and the output shaft of the drive motor 21 is connected to the turntable 2 in a transmission connection.

[0025] Working principle: During use, ceramic circuit boards to be transferred are placed on two support bars 6 of two belt assemblies 5 on each material rack 4, which are close to each other on one side and at the same horizontal plane. The turntable 2 is rotated by the drive motor 21, so that the ceramic circuit board on one of the material racks 4 is aligned with the slide table 31 of the transfer mechanism 3. The slide table 31 is driven by the electric slide rail 33 to move horizontally towards the material rack 4 until the suction nozzle 352 of the suction assembly 35 is directly above the top ceramic circuit board. During this process, the push plate 754 will... The push plate 753 is pushed to move towards the center of the turntable 2 against the elastic force of the elastic element 755. Since the ratchet 752 is elastically connected to the push plate 753, and the teeth of the ratchet 752 can only drive the ratchet 751 to rotate when it moves towards the transfer mechanism 3, the ratchet 752 does not drive the ratchet 751 when it moves away from the transfer mechanism 3 along with the push plate 753. Then, the suction assembly 35 is driven to move down by the telescopic drive 34 until the suction nozzle 352 of the suction assembly 35 can pick up the ceramic circuit board. Then, through... The telescopic drive 34 drives the suction assembly 35 to move upward and reset, and the electric slide rail 33 drives the slide table 31 to move in the opposite direction and reset, so that the suctioned ceramic circuit board is transferred to the preset position. During the reset process of the slide table 31, the push plate 754 gradually moves away from the abutment plate 753. Under the elastic action of the elastic member 755, the abutment plate 753 drives the ratchet 752 to gradually move towards the transfer mechanism 3. At this time, the ratchet 752 drives the ratchet wheel 751 to rotate, thereby the ratchet wheel 751 drives the worm gear 74 to rotate, and the worm gear 74 then drives the worm wheel 73 to rotate. The worm gear 73 drives the coaxial transmission gear 71 to rotate, which in turn causes the two transmission gears 71 to rotate synchronously in opposite directions. Consequently, the two belt assemblies 72 rotate synchronously with their respective transmission gears 71, and finally, the two belt assemblies 5 on the material preparation rack 4 rotate synchronously with their respective belt assemblies 72. Specifically, the two belt assemblies 5 on the material preparation rack 4 are configured to move the support bars 6 gradually from bottom to top, so that the ceramic circuit boards on each support bar 6 can gradually rise to a position that is convenient for the transfer mechanism 3 to pick up the materials.

[0026] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
