Description

Circuit substrate film pasting equipment and film pasting method

Technical Field

The invention relates to the field of circuit substrates, in particular to a circuit substrate film pasting device and a film pasting method.

Background

The circuit substrate product comprises circuit substrate, positioning jig and protection film: the positioning jig is fixed on two sides of the circuit substrate and movably connected with the circuit substrate; the protective film is attached to the surface of the circuit substrate and is not contacted with the positioning jig. The film pasting process of the circuit substrate mainly comprises the following steps: 1) placing the circuit substrate and the positioning jig connected with the circuit substrate into a material storage mechanism, and moving the circuit substrate and controlling the output of the circuit substrate by the material storage mechanism; 2) the material storage mechanism pushes the circuit substrate to the blanking mechanism, and the blanking mechanism quickly blanks the circuit substrate; 3) the circuit substrate is blanked to a mounting device, a film supply mechanism in the mounting device conveys protective films for a film mounting process, and a film pulling mechanism and an upward jacking mechanism mount the protective films to the surface of the circuit substrate; 4) the film pressing device rolls the surface of the circuit substrate on which the protective film is pasted, so that bubbles between the circuit substrate and the protective film are removed, and the pasting of the protective film is more uniform; 5) the moving device moves the rolled circuit substrate to the blanking device; 6) the blanking device carries out circular blanking on the circuit substrate product to complete the film pasting process of the circuit substrate. With the development of the circuit substrate industry, the circuit substrate film pasting equipment has more and more important position.

The prior art has the following defects: 1. when the circuit substrates are pushed and loaded, the driving mechanism drives the storage box to move to a loading station, and then the circuit substrates are manually moved to the corresponding multilayer grooves of the storage box; the grooves in the storage box are through-hole grooves, positioning assemblies for the circuit substrates are not arranged, and after the circuit substrates are manually placed into the through-hole grooves of the storage box, the multilayer circuit substrates need to be manually aligned; due to the lack of accuracy of manual alignment of the multilayer circuit substrates, some circuit substrates are recessed between an upper layer circuit substrate and a lower layer circuit substrate, and the gap between two adjacent layers of circuit substrates is narrow, so that great inconvenience is brought to manual alignment of the circuit substrates; moreover, when the front and the back of the storage box are respectively connected with the blanking mechanism and the circuit substrate pushing mechanism to be close, the front and the back alignment accuracy of the required circuit substrate is higher; when the circuit substrate is manually aligned, due to the fact that no positioning assembly is lack of accuracy, part of circuit substrates are prone to protruding forwards and backwards, when the storage box returns to the position respectively connected with the blanking mechanism and the circuit substrate pushing mechanism from the manual feeding station, the protruding circuit substrates are prone to colliding with the blanking mechanism and the circuit substrate pushing mechanism, and therefore connection of the storage box forwards and backwards is affected. 2. When the circuit substrate is blanked, the sucking disc mechanism reaches the position of the circuit substrate, the sucking disc sucks the circuit substrate, then the moving mechanism acts to drive the sucking disc mechanism to reach the blanking position, and the sucking disc mechanism loosens the circuit substrate to complete blanking of the circuit substrate; the whole blanking process needs a plurality of steps of moving the mechanism back and forth, sucking and loosening by the sucking disc mechanism and the like, so that the complexity of the blanking process of the circuit substrate is increased; and the sucking disc mechanism and the moving mechanism can only suck and move one circuit substrate in one blanking process, so that the moving time of the circuit substrate in each blanking is increased, and the blanking efficiency of the circuit substrate is reduced. 3. When the protective film is fed, after the protective film is cut by the cutting assembly, the extending end of the protective film is away from the pressing end of the protective film by a certain distance, and the protective film is a free section for a next station mechanism to grab the protective film; and because the protective film material is softer, the protective film stretches out the end and can warp along with the circulation of air in the space effect for the protective film stretches out the position of end for next station mechanism and changes, thereby influences the accuracy that the protective film pasted the dress. 4. When the circuit substrate is pasted with the protective film, the circuit substrate moves to drive the protective film wound on the coiling roller to move along with the circuit substrate so as to paste the protective film on the circuit substrate; the circuit substrate is large in size, and can only move at a low speed when moving in order to ensure that the circuit substrate moves stably, so that the process of mounting the protective film is long, and the mounting time of the protective film is prolonged. 5. When the circuit substrate with the attached protective film is blanked, only one blanking station is used for placing the circuit substrate with the attached protective film, and then the circuit substrate at the blanking station is manually moved away; the moving device in the blanking process can move the circuit substrate which is pasted with the film later to the blanking station for blanking from the processing station after the circuit substrate which is pasted with the film is moved away manually, so that the waiting time of the moving device is prolonged, and the blanking efficiency of the circuit substrate is reduced.

The circuit substrate film pasting equipment and the film pasting method adopting the technical scheme have the advantages that:

1. the material storage mechanism is in the working process: the material storage driving cylinder acts to drive the material storage box to move to the material loading station along the material storage driving guide pillar, and a plurality of circuit substrates connected with the positioning jig are manually loaded into a material storage box groove in the material storage box; at the moment, the material storage blocking cylinder is in an extending state, and the material storage blocking plate extends out of the groove of the material storage box to block the circuit substrate; the front end surface of the loaded circuit substrate is tightly attached to the rear end surface of the material storage barrier plate; the material storage driving cylinder acts to drive the material storage box to move to a position connected with the material storage pushing assembly; the material storage blocking cylinder contracts to drive the material storage blocking plate connected with the material storage blocking cylinder to contract to the outside of the groove of the material storage box, and the material storage blocking plate does not block the circuit substrate; the material storage pushing cylinder acts to drive the material storage pushing plate to extend out, and the material storage pushing plate extends out to push the circuit substrate aligned with the material storage pushing plate to move forwards so as to push the circuit substrate into the blanking mechanism to complete the material storage process of the circuit substrate. By arranging the material storage blocking assembly, when the circuit substrate is manually fed, the front end face of the circuit substrate is tightly attached to the rear end face of the material storage blocking plate so as to realize the positioning of the circuit substrate; when the front end surfaces of the circuit substrates are tightly attached to the rear end surface of the material storage blocking plate, the front end surfaces of the circuit substrates are aligned with each other; moreover, because the lengths of the circuit substrates are the same, the rear end faces of the circuit substrates are aligned with each other, so that part of the circuit substrates are prevented from being recessed among the multilayer circuit substrates, and the inconvenience of manually aligning the circuit substrates recessed among the multilayer circuit substrates is avoided; meanwhile, when the front and back of the storage box are respectively connected with the blanking mechanism and the circuit substrate pushing mechanism at a short distance, the storage box returns to the connection positions with the blanking mechanism and the circuit substrate pushing mechanism from the manual feeding station, and the plurality of circuit substrates are positioned by the storage blocking plates and are aligned with each other front and back, so that the front and back bulges of partial circuit substrates cannot be caused, and the front and back end surfaces of the circuit substrates are not contacted with the blanking mechanism and the circuit substrate pushing mechanism; thereby avoiding the contact collision of the blanking mechanism and the circuit substrate pushing mechanism which are respectively connected with the front and the back of the storage box.

2.

By arranging the blanking screw guide rail assembly 122, the blanking box 123 and the conveying belt assembly 124; when the circuit substrate is blanked, only two steps of driving the circuit substrate to move downwards by the blanking box 123 and driving the circuit substrate moved downwards by the conveyor belt assembly 124 are needed, and compared with four steps of driving the suction cup to move downwards, driving the suction cup to move upwards, driving the moving mechanism to move forwards and driving the moving mechanism to move backwards when the suction cup moves and blanks, the steps of blanking the circuit substrate are reduced, and the complexity of the blanking process of the circuit substrate is reduced; meanwhile, the blanking box 123 is provided with a plurality of blanking box grooves 1232, the blanking box grooves 1232 are arranged in a layered manner, and a plurality of circuit substrates are respectively arranged in the blanking box grooves 1232; when the circuit substrates are blanked, the circuit substrate at the lowest layer is firstly contacted with the conveyor belt assembly 124, then the conveyor belt assembly 124 conveys the circuit substrate to the next station to complete the blanking of the circuit substrate at the lowest layer, and then the blanking box 123 directly moves downwards to contact the circuit substrate at the upper layer with the conveyor belt assembly 124 until the circuit substrates in all the blanking box grooves 1232 of the blanking box 123 are blanked; that is, after the feeding of the blanking box 123 is completed, the continuous blanking of a plurality of circuit substrates can be realized in one blanking process, and the intermittent blanking of only a single circuit substrate in one blanking process and the process of moving the circuit substrate every time of blanking are avoided, so that the total moving time of the circuit substrate during the intermittent blanking of the single circuit substrate is reduced, and the blanking efficiency of the circuit substrate is improved.
