Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.
Example (b):
referring to fig. 1, the embodiment provides a patch paste brushing device, which includes a machine table 1, an installation frame 2 disposed on the machine table 1, a lifting mechanism 3 disposed between the machine table 1 and the installation frame 2 and used for driving vertical displacement of the installation frame 2, a paste brushing mechanism 6 disposed on the installation frame 2, a steel mesh 4 disposed on a lower portion of the installation frame 2, and a driving mechanism disposed on the installation frame 2 and used for driving lateral displacement of the paste brushing mechanism 6.
Wherein lifting mechanism 3 can adopt the pneumatic cylinder, through installing the pneumatic cylinder on board 1 to install mounting bracket 2 at the output axle head of pneumatic cylinder, so through the work of pneumatic cylinder, lifting/transfer mounting bracket 2. Be provided with the tool 11 of placing the paster on the upper wall of board 1, during operation, place the paster on tool 11, reuse pneumatic cylinder drives mounting bracket 2 and moves down, makes the mesh of steel mesh 4 press on the paster on tool 11, alright begin the work of brushing cream.
The driving mechanism can adopt a rodless cylinder 5 or a lead screw motion module, and is not limited herein; in the embodiment, the rodless cylinder 5 is taken as an example, the rodless cylinder 5 is arranged on the mounting frame 2, and the paste brushing mechanism 6 is arranged on a sliding block of the rodless cylinder 5; in this way, the rodless cylinder 5 drives the paste brushing mechanism 6 to move transversely left and right, and the paste brushing action is completed.
The paste brushing mechanism 6 comprises a mounting seat 61 fixedly mounted on the driving mechanism and two scraper assemblies symmetrically arranged on the mounting seat 61 and used for brushing paste. One of the doctor assemblies is described below:
as shown in fig. 2, the scraper assembly includes a blade holder 621, a primary scraper 622, a secondary scraper 623, and a driving element disposed on the mounting base 61 for driving the blade holder 621 to vertically displace; wherein the driving member adopts a cylinder 624. The cylinder 624 is actuated to displace the blade holder 621 up/down.
An installation groove 73 for installing a main scraper 622 is formed in the inner side wall of the cutter holder 621, and a plurality of screws 7 perpendicular to the cutter holder 621 are fixedly connected in the installation groove 73; for example, this embodiment adopts two screws 7, and every screw 7 all is equipped with the lock nut 8 rather than the adaptation, and for the convenience of bare-handed rotatory lock nut 8, be equipped with the rotor 81 of a set of symmetry setting on lock nut 8, provide the impetus for the hand through rotor 81.
As shown in fig. 3, the main scraper 622 is provided with a mounting hole 71 for the screw 7 to pass through; during mounting, the main scraper 622 is inserted into the screw 7 through the mounting hole 71.
The auxiliary scraper 623 is arranged on the cutter holder 621 through a connecting piece; the secondary blade 623 is spaced apart from and parallel to the primary blade 622, wherein the secondary blade 623 is located outside the primary blade 622, and the primary blade 622 is flush with the bottom of the secondary blade 623.
Specifically, the connecting member includes a transverse plate 625 and a plurality of connecting arms 626 arranged on the transverse plate 625 at intervals, wherein one end of each connecting arm 626 is fixedly connected with the transverse plate 625, and the other end is fixedly connected with the auxiliary scraper 623; the cross plate 625 and the connecting arm 626 may be integrally formed.
A through hole 72 for the screw rod 7 to pass through is formed in the transverse plate 625; the transverse plate 625 is inserted into the screw rod 7 through the through hole 72. During installation, firstly, the main scraper 622 is arranged on the screw rod 7 in a penetrating mode through the installation hole 71, then the through hole 72 of the transverse plate 625 is aligned with the screw rod 7 and arranged on the screw rod 7 in a penetrating mode, finally the locking nut 8 is screwed on the screw rod 7, the transverse plate 625 and the main scraper 622 can be tightly abutted at the same time through the locking nut 8, and installation of the scraper is completed. Similarly, when the scraper is disassembled, the main scraper 622 and the auxiliary scraper 623 can be taken down together with the connecting piece only by screwing off the lock nut 8, so that the main scraper 622 and the auxiliary scraper 623 can be cleaned. It can be seen that the mounting/dismounting process is simplified.
The implementation principle is as follows:
after the steel mesh 4 presses the patch, the first cylinder 624 drives the main scraper 622 and the auxiliary scraper 623 below the first cylinder to press downwards, then the rodless cylinder 5 drives the main scraper 622 and the auxiliary scraper 623 to move rightwards, and the solder paste is scraped through the inner side wall of the main scraper 622 to brush the solder paste; when the main scraper 622 moves to the other side, the first air cylinder 624 drives the main scraper 622 and the auxiliary scraper 623 to reset, then the second air cylinder 624 drives the main scraper 622 and the auxiliary scraper 623 below the first air cylinder to press downwards, and then the rodless air cylinder 5 drives the main scraper 622 to move leftwards to finish paste brushing.
In this process, the secondary scraper 623 scrapes the solder paste overflowing from the outer side wall of the primary scraper 622 toward the center to ensure that the solder paste can be scraped again by the primary scraper 622 for use.
Above only the typical example of the utility model discloses, in addition, the utility model discloses can also have other multiple concrete implementation manners, all adopt the technical scheme that equivalent replacement or equivalent transform formed, all fall in the utility model discloses the scope of claiming.
