Abstract
The utility model relates to an emptying control device in an integrated circuit lead frame production line, which comprises a base and a fixed plate which is arranged on the base along the vertical direction. The lateral part of the fixed plate is provided with a U-shaped guide plate. The guide plate is vertical to the fixed plate. An emptying photoelectric detector is arranged above the bottom of the guide plate. The middle part of the guide plate is provided with a tailing photoelectric detector. Both the emptying photoelectric detector and the tailing photoelectric detector are in communication connection with a leveler controller. Both an emptying machine and a punching machine are controlled by a controller. The emptying control device is arranged between a lever and the punching machine in the integrated circuit lead frame production line and can be used for controlling the emptying speed and the punching speed according to the condition of the production line so that an integrated circuit lead frame is prevented from being damaged due to ground friction or being deformed due to hooking and materials are prevented from entering a die and being hooked to cause damage to the die.
Description
Technical field
The utility model relates to the control feeding device in a kind of circuit lead frame production line.
Background technology
Circuit lead frame is when producing, and lead frame carries out punch forming by punch press behind the level(l)ing machine blowing.Because the drawing velocity of level(l)ing machine dispensing speed and punch press is difficult to be consistent, when dispensing speed during greater than drawing velocity, the lead frame between straightener and punch press can be because of the long ground that is dragged to, thereby cause lead frame impaired; When the level(l)ing machine dispensing speed is slower than drawing velocity, because lead frame feeding smoothly can cause prepared circuit lead frame modification even cause mould impaired.
The utility model content
The utility model technical problem to be solved is: provide a kind of can be according to the production line situation, control dispensing speed and drawing velocity, thus prevent the control feeding device in the impaired circuit lead frame production line of lead frame modification or mould.
For addressing the above problem; The technical scheme that the utility model adopts is: the control feeding device in the circuit lead frame production line; Comprise base and be arranged on one on the base along the vertical fixed head that is provided with, the sidepiece of said fixed head is provided with U type stock guide, and is vertical each other between stock guide and the fixed head; The top, bottom of stock guide is provided with the blowing photoelectric detector; The middle part of stock guide is provided with end material photoelectric detector, and the blowing detector all communicates with punch press and level(l)ing machine controller with end material detector and is connected, and feeding machine and punch press are controlled by controller.
Said base is provided with material blocking rod, and material blocking rod is positioned at the outside of stock guide, and material blocking rod cooperates with the width adjustment of copper strips with distance between the fixed head.
Also be provided with two limited posts on the said fixed head, two limited posts lay respectively at the inboard at stock guide two ends, and there is the gap in two limited posts respectively and between the stock guide two ends.
The beneficial effect of the utility model is: the control feeding device in the above-mentioned circuit lead frame production line, it is simple in structure, easy to use.When the dispensing speed in the production line during greater than drawing velocity, it can control dispensing speed, thereby prevents that the lead frame between level(l)ing machine and punch press is dragged to the ground scratch or colludes repeatedly impaired because of feeding is long; When the level(l)ing machine dispensing speed is slower than drawing velocity, because lead frame feeding smoothly can cause prepared circuit lead frame modification even cause mould impaired.

Fig. 2 is the plan structure sketch map of Fig. 1;
Among the figure: 1, fixed head, 2, stock guide, 3, the blowing detector, 4, end material detector, 5, material blocking rod, 6, base, 7, limited post.
Embodiment
Through specific embodiment the control feeding device in the utility model circuit lead frame production line is done further to describe in detail below.
Like Fig. 1, shown in Figure 2; Control feeding device in the circuit lead frame production line; Comprise base 6 and be arranged on one on the base along the vertical fixed head 1 that is provided with, the sidepiece of said fixed head 1 is provided with U type stock guide 2, and is mutual vertical between stock guide 2 and the fixed head 1; The top, bottom of stock guide 2 is provided with blowing detector 3; The middle part of stock guide 2 is provided with end material detector 4, and blowing detector 3 all communicates with the controller (not shown) with end material detector 4 and is connected, and level(l)ing machine and punch press are controlled by controller.Said base 6 is provided with material blocking rod 5, and material blocking rod 5 is positioned at the outside of stock guide 2, and material blocking rod 5 can cooperate with the width adjustment of lead frame with distance between the fixed head 1.Also be provided with the inboard that 7, two limited posts 7 of two limited posts lay respectively at stock guide 2 two ends on the said fixed head 1, and there is the gap in two limited posts 7 respectively and between stock guide 2 two ends.
The operation principle of the utility model is: during use; Above-mentioned control feeding device is arranged between the level(l)ing machine and punch press in the circuit lead frame production line; The lead frame that passes from level(l)ing machine passes through between fixed head 1 and material blocking rod 5; And copper strips penetrates from the other end from an end of stock guide 2 and passes, and is fastened between stock guide 2 and the limited post 7, gets into punch press then.When the dispensing speed in the production line during faster than drawing velocity; Copper strips between straightener and punch press is because of the long bottom that is dragged to stock guide 2; Blowing detector 3 detects the copper strips signal and is sent to controller at this moment, and controller control level(l)ing machine stops blowing, when blowing detector 3 detects less than the lead frame signal; Controller control feeding machine continues blowing, and to be dragged to ground impaired because of long thereby can prevent lead frame between level(l)ing machine and punch press; When the dispensing speed in the production line is slower than drawing velocity; Lead frame between straightener and punch press is because of too short linearly state; End material detector 4 detections this moment are less than the copper strips signal and be sent to controller, and controller control punch press stops punching press, when end material detector 4 detects the copper strips signal; Controller control punch press continues punching press, thereby prevents that circuit lead frame modification or mould are impaired.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection range of the utility model.
