Description

Technical Field

[0001] The utility model relates to the technical field related to chip inserting machines, in particular to an adaptive chip inserting machine transmission structure. Background Art

[0002] The chip inserter is mainly used to insert chips into circuit boards to ensure that the chips can be correctly connected with other components on the circuit board. Therefore, the chip inserter needs to be driven by a transmission structure during operation. The transmission structure is usually achieved through the meshing transmission between gears and racks during operation. Racks with longer specifications are usually assembled in a splicing manner to achieve long-distance meshing with gears. However, the existing transmission structure still has the following disadvantages in actual use:

[0003] After multiple racks are spliced, slight height differences are inevitable at the joints, resulting in insufficient meshing between the gears and different racks, which in turn affects subsequent transmission. Therefore, there is a lack of a structure to ensure that the gears are always fully meshed with the racks. To address the above problems, innovative designs are urgently needed based on the original transmission structure. Utility Model Content

[0004] The purpose of the present utility model is to provide an adaptive sheet inserting machine transmission structure to solve the problem proposed in the above background technology that slight height differences are inevitable at the connection points of multiple racks after splicing, resulting in insufficient meshing between the gears and different racks, thereby affecting subsequent transmission. Therefore, there is a lack of a structure to ensure that the gears are always fully meshed with the racks.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an adaptive sheet inserting machine transmission structure, comprising a crossbeam, a motor is mounted below the crossbeam by bolts, and the output shaft of the motor is connected to a transmission shaft through a transmission assembly, the transmission shaft is rotatably arranged below the connecting beam, and the connecting beam and the crossbeam are fixedly connected;

[0006] It also includes: both ends of the connecting beam are connected to each other through a universal joint and a gear, and the gear and the rack are meshed, the rack is fixed to the surface of the mounting plate, and the racks are distributed at equal intervals;

[0007] The cleaning components are arranged at both ends of the transmission shaft, and the cleaning components are slidably arranged on the mounting plate through a support seat.

[0008] Preferably, the cleaning assembly includes a connecting shaft arranged on the side of the universal shaft, and the connecting shaft and the transmission shaft are connected by the universal shaft, and an impeller is fixedly installed on the end of the connecting shaft away from the universal shaft, which can drive the gear to slightly change its angle according to the action of the universal shaft, thereby ensuring sufficient engagement with the rack.

[0009] Preferably, a protective box is provided on the outer side of the impeller, and a connecting rod is fixed to the bottom of the protective box, and the end of the connecting rod away from the protective box is connected to a support seat, and when the connecting shaft rotates, the impeller can be driven to rotate, thereby generating airflow.

[0010] Preferably, the connecting rod and the support seat are slidably connected, and a pulley is embedded in the internal rotation of the support seat, and the pulley is in contact with the surface of the mounting plate. The setting of the support seat will not affect the movement of the gear and can ensure the stability of the protective box.

[0011] Preferably, air pipes are fixed on both sides of the protective box, and the end of the air pipe away from the protective box is connected to a bellows, and the end of the bellows away from the air pipe is fixed to a connecting pipe. The airflow in the protective box can be transmitted to the bellows through the air pipe and then enter the connecting pipe.

[0012] Preferably, the protective box is connected to each other through the air pipe and the bellows, and the bellows is connected to the air nozzle through the connecting pipe, and the air nozzles are evenly spaced on the connecting pipe. The airflow in the connecting pipe can eventually be discharged from the air nozzle and blown onto the gear and rack to clean them.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the adaptive inserting machine transmission structure has a drive gear shaft and a gear connected by a universal shaft. Therefore, when the gear is engaged with racks at different heights, the universal shaft can drive the gear to rotate slightly, thereby ensuring that the gear and rack are more fully engaged and avoiding affecting subsequent transmission. The specific contents are as follows:

[0014] 1. The motor drives the transmission shaft and gear to rotate. When the gear engages with racks at different heights, the universal joint at the end of the transmission shaft can drive the gear to rotate slightly to change the angle, thereby ensuring that the gear and rack are more fully engaged and the subsequent transmission is smooth.

[0015] 2. When the gear rotates, it can drive the connecting shaft to rotate synchronously, and then drive the impeller to rotate to generate airflow. The airflow can be transmitted to the bellows through the air pipe, then enter the connecting pipe and finally be discharged from the air nozzle to blow onto the rack and gear, playing a cleaning role;

[0016] Furthermore, during the movement of the gear, the support seat is driven to slide on the mounting plate through the pulley, and the support seat can be driven to slide on the connecting rod according to the height of the mounting plate, thereby ensuring the stability of the protective box during movement and not affecting the cleaning of the rack and gear.
