Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to an automatic unloading device for keycap carriers. Background Technology

[0002] After assembling the keycaps on the keyboard, the carrier used to hold the keycaps needs to be unloaded and recycled (at this time, the carrier is empty). Currently, for semi-automatic keyboard assembly machines, the unloading of the carrier is mostly done manually or by a robotic arm. Manual unloading is relatively inefficient, while the robotic arm unloading method requires precise control of its gripping action. Once a deviation occurs, it may damage the carrier, increasing production costs. At the same time, the maintenance cost of the robotic arm is high, and it needs to be maintained and repaired regularly, otherwise it is prone to failure, which will affect production efficiency.

[0015] Reference Figures 1 to 4As shown, this utility model provides an automatic feeding device for a keycap carrier. In one embodiment, it includes a first transmission line 1 and a second transmission line 2 arranged at one end of the first transmission line 1. The second transmission line 2 includes two feeding base plates 21. The two feeding base plates 21 are arranged in parallel and spaced apart, and two feeding brackets 22 are connected between the tops of the two feeding base plates 21. The two feeding brackets 22 are arranged in parallel and spaced apart, and a feeding conveyor belt module is installed on the opposite side of the two feeding brackets 22. A feeding lifting mechanism 23 is also installed between the two feeding brackets 22. Furthermore, a material distribution mechanism 24 is installed on each feeding bracket 22 on one side of the feeding lifting mechanism 23; a front guide plate 25 is installed on each end of the top of one feeding bracket 22 on one side of the feeding lifting mechanism 23, and a rear guide plate 26 is installed on each end of the top of the other feeding bracket 22 on the other side of the feeding lifting mechanism 23; the front guide plate 25 and the rear guide plate 26 are both arranged in a vertical direction; a strip-shaped hole is also opened on one side of the rear guide plate 26 in a vertical direction, and a photoelectric sensor 27 is installed on the rear guide plate 26 at the corresponding position of the strip-shaped hole.

[0016] In this embodiment, the first transmission line 1 is used to transport the carrier carrying keycaps to the loading position, where an external robot will transfer the keycaps to the assembly table. Subsequently, the first transmission line 1 transports the empty carrier to the second transmission line 2. The unloading conveyor belt module includes a conveyor belt assembly and a transmission motor assembly for driving the conveyor belt assembly. The unloading conveyor belt module is used to connect the carrier transported by the first transmission line 1 and transport it to the unloading lifting mechanism 23. The unloading lifting mechanism 23 can lift the carrier and detach it from the first transmission line 1, while the material distribution mechanism 24 can lift the carrier and gradually stack it. At the same time, a front guide plate 25 and a rear guide plate 26 are provided to guide and limit the stacking of empty carriers to prevent the carriers from shaking. A photoelectric sensor 27 is also installed on the rear guide plate 26 to detect the position of the carrier.

[0017] Preferably, the unloading lifting mechanism 23 includes an unloading mounting plate 231 connected between two unloading base plates 21, a lifting drive assembly mounted on the unloading mounting plate 231, an unloading top plate 232 connected to the lifting drive assembly, and an unloading support plate 233 mounted on the top of the unloading top plate 232; the unloading support plate 233 is also equipped with an unloading positioning pin. The lifting drive assembly includes a cylinder, which can drive the unloading top plate 232 to move the unloading support plate 233 (the unloading support plate 233 is used to support the carrier) up and down, thereby completing the lifting action of the carrier.

[0018] Meanwhile, to improve the stability of the lifting and lowering of the feeding pallet 233, a feeding guide rod 234 is connected to each of the four bottom corners of the feeding top plate 232; a first linear bearing is also installed on the feeding mounting plate 231 at the position corresponding to the feeding guide rod 234, and the feeding guide rod 234 is connected to the first linear bearing.

After the material lifting mechanism 23 lifts the carrier, the material distribution translation cylinder 242 drives the material distribution vertical plate 243 to move the material distribution insert plate 244 to the bottom of the carrier to hold the carrier. The material lifting mechanism 23 then resets and lifts another carrier. At this time, the material distribution translation cylinder 242 drives the material distribution insert plate 244 to retract, and the carrier on the material distribution insert plate 244 is stacked onto the carrier on the material lifting mechanism 23. Subsequently, the material lifting mechanism 23 drives the carrier to rise one stroke, and the material distribution translation cylinder 242 drives the material distribution insert plate 244 to move to the bottom of the carrier to hold the carrier. The above actions are repeated to complete the stacking and unloading of the carrier. In addition, a material distribution block 245 is connected to the lower part of one side of the material distribution vertical plate 243. The material distribution block 245 can limit the side of the carrier.

This structural design allows the first guide strip 20 to form a stable guide channel, guiding and limiting the stacked empty carriers, and preventing the carriers from shaking or deviating. Meanwhile, a first guide sleeve 221 is installed on one of the feeding brackets 22; the second transmission line 2 also includes an adjusting guide rod 222, which moves through the first guide sleeve 221 and is connected to the other feeding bracket 22 at one end. This allows for easy adjustment of the distance between the two feeding brackets 22, thus adapting to the feeding requirements of keycap carriers of different specifications. It is highly versatile. After adjusting the distance between the two feeding brackets 22, screws are then driven into the holes at the bottom of the feeding brackets 22 to fix them to the feeding base plate 21.

[0021] In one embodiment, the first transmission line 1 includes two first transmission frames 11; the two first transmission frames 11 are arranged in parallel and spaced apart, and a first transmission belt module is installed on each opposite side of the two first transmission frames 11; a clearance slot 12 is opened at each of the top two ends of the first transmission frame 11, and the portion of the first transmission belt module located in the clearance slot 12 is arranged below one side of the clearance slot 12. This structural design provides space for the installation and operation of the first lifting mechanism, so that the first lifting mechanism can lift the carrier, which is convenient for the robot arm to transfer the keycap.

[0022] Preferably, a first lifting mechanism is also installed on the first transmission line 1; a lifting mounting plate 13 is connected to the other side of each of the first transmission frames 11, and a lifting guide rail is arranged on one side of the lifting mounting plate 13 in the vertical direction; the first lifting mechanism includes a lifting support plate 14 and two lifting cylinders 15; the two lifting cylinders 15 are respectively installed on one side of a lifting mounting plate 13; the lifting support plate 14 has a rectangular hollow structure, and the bottom of both sides of the lifting support plate 14 are respectively connected to a lifting cylinder 15, and the two ends of the lifting support plate 14 are arranged through the clearance slots 12; the bottom two sides of the lifting support plate 14 are also connected to lifting connecting plates 16, and the lifting connecting plates 16 are slidably arranged on the lifting guide rail. The lifting cylinders 15 can drive the lifting support plate 14 to rise, thereby lifting the carrier, and the lifting connecting plates 16 on both sides of the bottom of the lifting support plate 14 are slidably arranged on the lifting guide rail, which can guide the lifting support plate 14 when it is raised and lowered, thereby improving its stability during the lifting and lowering movement.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
