This embodiment specifically as follows when combining current other tools to carry out the pressfitting:
the power supply of the tool is connected, the tool is in an initial state, the top cylinder 1 is in a retraction state, the elastic pressing module 6 is in a high position, the rodless cylinder 17 is in an extension state, and the product carrier plate 9 is outside the pressing region along with the extension state of the rodless cylinder 17.
The POS machine front shell 8 to be pressed is placed on a product support plate 9 in a specified direction, a button switch 13 is started, a rodless cylinder 17 is started to retract, a support plate bottom plate 10, a product support plate 9 and the POS machine front shell 8 to be pressed move towards a support side plate 7, when the rodless cylinder 17 retracts to a specified position, the support plate bottom plate 10, the product support plate 9 and the POS machine front shell 8 to be pressed stop at the current position, a sensor senses that the rodless cylinder 17 is in place, the sensor feeds back a signal to a single chip microcomputer, the single chip microcomputer controls a top cylinder 1 to be started, a movable end of the top cylinder 1 extends out, and an elastic pressing module 6 connected with the movable end of the top cylinder 1 moves downwards along a motion track of a linear guide rod 2 and a linear bearing 3 under the pushing action of the movable end of the top cylinder 1. When the rodless cylinder 17 retracts and stops, the stop position of the front shell 8 of the POS machine to be pressed is superposed with the position of the elastic pressing module 6, and the pressing area formed by the silica gel column 26 array in the elastic pressing module 6 is consistent with the position of the front shell 8 of the POS machine to be pressed, which needs to be pressed.
As the top cylinder 1 descends slowly, the elastic pressing module 6 starts to touch the TP of the front housing 8 of the POS machine to be pressed, in the process of touching, the stainless steel column 25 and the silica gel column 26 of the elastic pressing module 6 continuously give TP pressure to the front housing 8 of the POS machine to be pressed under the action of the spring 24, and continuously increase, when the top cylinder 1 descends to the limit position and does not descend any more, and the current position remains still, the elastic pressing module 6 also remains still at the current position, and the stainless steel column 25 and the silica gel column 26 still continuously give TP pressure to the front housing 8 of the POS machine to be pressed under the action of the spring 24, but the pressure does not increase any more. Because the stainless steel columns 25 and the silica gel columns 26 of the array are independent of each other, the uniformity of the pressure of the TP pressing area of the front shell 8 of the POS machine to be pressed is not influenced by factors such as plane precision, tolerance of products, assembly tolerance of the products and the touch screen module, glue dispensing amount and the like.
When the top cylinder 1 descends to the limit position, a sensor feeds back a signal to a single chip microcomputer, the single chip microcomputer controls a time relay to start timing, when the specified time is reached, the top cylinder 1 starts to retract, the movable end of the top cylinder 1 drives the elastic pressing module 6 to move upwards along the motion tracks of the linear guide rod 2 and the linear bearing 3, the rodless cylinder 17 inside the rack drives the support plate bottom plate 10, the product support plate 9 and the POS machine front shell 8 to be pressed to move towards the outside of the rack, and a worker takes down the pressed POS machine front shell, inspects the appearance and the pressing effect and puts the pressed POS machine front shell into a specified tray.
The effects in the present embodiment are specifically described as follows: the advantage of making silica gel column 26 densely arranged is to eliminate the tolerance influence of the front shell parts of the POS machine and the influence of uneven force of the pressing surface caused by the precision of the vertical movement of the tool and the precision of the pressing surface. The POS machine front shell is a plastic part manufactured by an injection molding process, the tolerance of the POS machine front shell is large, in addition, the tooling equipment is also machined and assembled, certain errors can exist in the POS machine front shell, and the errors can have certain influences if accumulated.
If the integrated pressing is made, the gluing surface is formed by subtracting the middle hollow part from the outline area of the touch screen, and the pressing block can only press the gluing surface area, so that when the pressing is performed, the silica gel is too soft, air in the hollow part is avoided in the middle of the silica gel to be discharged, then the touch screen assembly is adsorbed, and when the silica gel is too hard, the effect of eliminating accumulated errors cannot be achieved, so that the columnar spring 24 is selected to apply force for pressing, and the touch screen assembly and the front shell part of the POS machine can be ensured to be relatively uniformly attached and stressed in the gluing area.
To sum up, the utility model provides a pair of pressurize frock of unsteady pressfitting of POS machine touch-sensitive screen, the intensive range of pressfitting subassembly is pushed down by reciprocating the device drive pressfitting subassembly, along with elasticity pressfitting module begins to touch with the TP who treats pressfitting POS machine front shell, touching the in-process, nonrust steel column and silica gel column are under the effort of spring, the TP pressure of treating pressfitting POS machine front shell is given in the continuation to constantly increase, reach the assigned position until reciprocating the device, continuously exert pressure by nonrust steel column and silica gel column. Because the nonrust steel column of array and silica gel column are mutually independent and have selected the column spring to exert pressure and carry out the pressfitting, so treat that the degree of consistency of the pressfitting regional pressure of the TP of pressfitting POS machine front shell is not influenced by factors such as plane precision, the tolerance of product, the assembly tolerance of product and touch-sensitive screen module and point gum volume, make touch-sensitive screen subassembly and POS machine front shell part laminating atress relatively even, simultaneously through reciprocating the device, elasticity pressfitting module and material transport assembly's further structural limitation, make the elasticity pressfitting module of laminating in-process more reliable and more stable, thereby the laminating quality of touch-sensitive screen module has been improved.
