All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As shown in fig. 1 to 6, the present application provides an automatic conveying device of a circuit board drilling device, which comprises a mechanical arm 1 and a horizontal fine adjustment component 2 arranged at the end of the mechanical arm 1, wherein the horizontal fine adjustment component 2 is used for clamping a circuit board and pushing the circuit board to a drilling area after fine adjustment and correction of the circuit board to a horizontal state.

When the application is used, the mechanical arm 1 is used for driving the horizontal fine adjustment component 2 to move so as to transport the circuit board to a designated area.
When the horizontal fine adjustment component 2 is used, the position of the adsorption structure 202 is fixed by the rotation adjustment component 201, the adsorption structure 202 adsorbs a circuit board to be transported to the horizontal reference surface of the auxiliary correction structure 203, and at the moment, the position of the adsorption structure 202 is fixed by the rotation adjustment component 201 in a contact way, so that the circuit board drives the adsorption structure 202 to rotate under the contact pressure between the circuit board and the horizontal reference surface, the circuit board is corrected to be in fit with the horizontal reference surface, and the problem that the production quality is influenced by deformation caused by the fact that the circuit board is placed to a drilling position and is in a non-horizontal state is avoided.

When the rotation adjusting structure 201 is used, when the adsorption structure 202 adsorbs a circuit board, the side fixing assemblies 207 simultaneously fix the two ends of the connecting shaft 205, so that the stability of the adsorption structure 202 during the adsorption of the circuit board is ensured.
When the circuit board contacts with the horizontal reference surface of the auxiliary correction structure 203, the side fixing component 207 contacts with the fixing of the connecting shaft 205, so that the circuit board and the adsorption structure 202 rotate under the action of the contact pressure between the circuit board and the horizontal reference surface until the circuit board is attached to the horizontal reference surface, and at this time, the side fixing component 207 again fixes the connecting shaft 205, so that the horizontal state of the circuit board is ensured not to change.
The torsion spring is used for resetting the connecting shaft 205 through elasticity generated after deformation, so that conditions for adsorbing and transporting the circuit board by the adsorption structure 202 are the same, thereby accurately and stably adsorbing the circuit board, and the elasticity coefficient of the torsion spring is smaller, so that the connecting shaft 205 is only required to be ensured to reset, and the problem that the contact pressure between the circuit board and the auxiliary correction structure 203 is larger and causes deformation damage due to larger elasticity generated after deformation due to larger elasticity coefficient of the torsion spring is avoided.
The side fixing assembly 207 comprises two locking screws 208 which are arranged on the inner wall of the U-shaped groove 204 along the radial direction of the connecting shaft 205, the two locking screws 208 are symmetrically arranged by taking one diameter of the connecting shaft 205 as a symmetrical center, each locking screw 208 is in threaded connection with an arc plate 209 which is in sliding connection with the inner wall of the U-shaped groove 207, and the opposite arc inner sides of the two arc plates 209 are respectively provided with a first friction layer 210 which is used for contacting with the surface of the connecting shaft 205;
wherein the two circular arc plates 209 are not in contact with each other at the ends of the two circular arc plates 209 when they are in surface contact with the connection shaft 205.
When the side fixing assembly 207 is used, the two circular arc plates 209 are driven to move in opposite directions or move in opposite directions through the locking screw 208, when the two circular arc plates 209 move in opposite directions, the fixing restriction on the connecting shaft 205 is released, and when the two circular arc plates 209 move in opposite directions, the first friction layer 210 is in contact with the surface of the connecting shaft 205 and generates pressure, and the connecting shaft 205 is limited to rotate through the friction force generated between the first friction layer 210 and the connecting shaft 205, so that the fixing of the connecting shaft 205 is completed.
In this embodiment, the first friction layer 210 is a material with a larger friction coefficient with the connecting shaft 205, and may be made of rubber or other materials.

The stability of the circular arc plate 209 in fixing the connection shaft 205 is further enhanced by the provision of the reinforcing ribs 211.
The fact that the ends of the two arc plates 209 are not contacted avoids the problem that the connecting shaft 205 is poor in fixing stability due to the fact that the arc plates 209 are not tightly contacted with the connecting shaft 205.

When the arc plate 209 is away from the connection shaft 205, the arc plate 216 moves in the axial direction of the connection shaft 205 out of contact with the inner wall of the circumferential groove 218 by the drive of the auxiliary screw 214, and at this time the connection shaft 205 rotates normally.
When the first friction layer 210 on the arc plate 209 contacts and abuts against the surface of the connecting shaft 205, the auxiliary screw 214 drives the arc plate 216 to move along the circumferential groove 218 towards the direction approaching the locking screw 208 until abutting against the inner wall of the circumferential groove 218, and the axis of the connecting shaft 205 is further limited by the friction force generated by the pressure between the second friction layer 217 and the inner wall of the circumferential groove 218, so that the stability of the connecting shaft 205 in the fixed position is further improved.
The arcuate surface of the arcuate plate 216 is adapted to engage and not contact the inner bottom of the circumferential groove 218, thereby avoiding interference with movement of the arcuate plate 216 and increasing the contact area between the second friction layer 217 and the circumferential groove 218, thereby increasing the contact stability between the second friction layer 217 and the inner wall of the circumferential groove 218.

Next, the horizontal base 219 is used to provide a horizontal reference, and at the same time, the circuit board is commonly carried by the two sets of balls 220 to ensure the horizontal state of the circuit board.
The horizontal lifting assembly 222 is used for lifting the circuit board after the circuit board is horizontally corrected, so that the circuit board is prevented from influencing the horizontal state due to the state change of the gap between the balls 220 when the mechanical arm 1 is pushed in the horizontal direction.
