New Description: [New Technology Field] This creation is about a broken needle detection device for a printed circuit board drilling machine. The Lu finger-type design is simple, easy to use and convenient, and can be used to detect the drill needle. And the accuracy and immediacy of 'and thus the drilling of the printed circuit board is more efficient and succinct': - and the practical applicability, ideality and progress 'and the unprecedented hole _ _ broken needle detection Device improvement. I [Prior Art] According to the 'drilling of the printed circuit board, due to the large number of special machines for drilling the aperture plate and small holes, it is not set to operate at high speed, β, ', white, p, and/or In order to ensure the quality of the wrong holes, each σ is equipped with a riding device, 俾 monitoring (4), _received to break, ', and thus to prevent circuit board leakage drilling or drilling is not effective. Kind: In addition, the detection method and device for detecting whether the drill needle is broken or not according to the conventional method are as follows: the following two divisions touch the first figure, mainly in the spindle lifting mechanism (not shown), the position = ρ Brush circuit board 1 (the pressure foot 1 按 is provided with a dust collecting tube, the dust collecting tube 2 has & dust thin Μ ' and the dust side device M JL is connected through a line to a == (Fig. This embodiment is mainly used for printing by the drilling when the drilling operation is performed on the printed circuit board κ by a drill Α provided on the spindle rotating shaft: anti-dust (dust) Κ, Through the pressure foot 1 (), the sleeve magic and the dust collection tube (8) will be detected and detected when passing through the dust detector M. At the same time, through the electric automatic controller (Fig. v, ', operation The instrument will show that the drill pin is in a normal state; 6 M335908 On the contrary, if the ride is fine, the automatic controller of the fine electrical control box of the device will operate, and the instrument will be 丨 = dust = dust detector Detecting the drilling dust, as a, 疋 using the powder j ===__' to know the drill to tear, tender __f chest plum, and cause the road In short, due to the shortcomings of defective products; in other words, because of the _ fine Cui, the poorness of the 'drilled needle often after the break, she _ do the drilling action, the mechanical needle of the instant needle will often be issued or Zheng Yi compiled. Finance, fine friends (micro-break) situation when 'drilled to the surface of the printed circuit board, will still produce the heart two for the dust detector to sense, and the machine A lion chain _ _ still produce the dust (powder) is not sure and printed The coffee flap, which (four) is caused by the square hole lowering mechanism 1 and the grounding_hole machine is insulated, and the absolute door is attached to the spindle lifting mechanism 1 and the machine reciprocating table that provides the mounting 2 Ϊ木=f can shaft W ^ _ job tank insulator B (if the wire is connected to the electric eliminator G and is transmitted through the misaligned ribs for the spindle A fixed spindle rotation axis) A small potential difference generated between 202 (when any motor is shipped, M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M The foot 〇 touches the printed circuit board κ, and the main shaft 2G is lowered to press the argon A of the arbor on the rotating shaft 2G1 to The brush circuit board κ ... the small potential difference between the spindle body housing 2G2 and the rotating shaft center 2G1 can be rotated via the rotating shaft 2, the iron pin A, the printed circuit board [drive mechanism C, the table 5 cum. Shape (four), and the box _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In the case of a fracture, as the spindle 20 runs from the highest point to the hole, it is inevitable that the printed circuit board K cannot be touched, and the control of the electronic control II cannot generate the trigger money, or the tip of the drill pin is slightly collapsed. The operation of the spindle 20 from the highest point of the drill hole is also inevitable due to delayed contact with the printed circuit board. K 'causes the controller to delay the generation of the trigger signal phenomenon. Further, the control of the electric control box is based on the fact that the trigger signal cannot be generated or delayed, and the instrument (not shown) can immediately display the abnormality of the iron needle. Achieve the purpose and effect of the expected test. It is a kind of operation mode. It is indeed more accurate, accurate and immediate effect on the detection of the abnormality of the drill needle > and it also effectively reduces the occurrence of defective products on the printed circuit board. However, in the secret service, the operator π feels that there is still a slight lack of ointment; that is, because the driving mechanism C must be applicable to various printing jobs, so its overall structure is relatively small, and there is an increase in the production of troublesome β cost phenomenon. In particular, it is necessary to perform a separate loading and unloading operation for each of the printed circuit boards (ie, 'the driving mechanism must be placed before the drilling of the printed circuit, and the printed circuit board is turned into an iron hole.' The drive mechanism needs to be disassembled), and there are troubles, inconveniences, low cost, and reduced production efficiency. Of course, the drive mechanism is continuously operated and installed, and the M335908 is disassembled, and its failure rate and loss rate are There are also disadvantages of relative improvement. Re-moving mechanism cf wire machine red work # 5 phase due to the driver's workbench - the fixed garden, for this reason, the various sizes = standing often "placed in the workbench position, 1 2: hole inconvenience and It is necessary to constantly adjust the whisker phenomenon of the drive mechanism according to the installation position.镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔 镔. Self-awareness plus [new content] The main purpose of the creation of this book is to provide an improvement of the circuit-measuring device of the species, in the first, 兮 h + h, the use of the broken needle to check the Μ 升降 lift mechanism and grounding When the machine component is in the state of a conduction loop, the drilling causes the pressure foot to touch the printed circuit board... the pressure foot, the printed circuit board and the ground will be-conducted, and the spindle-driven pin 7 is printed. The circuit tree, the small potential difference between the body casing and the _-thin, can be directly turned on by the rotation of the fine, the needle, the printed circuit board, the pressure foot and the ground, and the side squeezing device generates the trigger signal and the detection drill accordingly. Whether the needle is abnormal or not, and then the implementation of the needle _ needle can be combined with _ easier, convenient, accurate, and can improve the efficiency of production. The other purpose of this creation is to provide a simple design, easy to use, and convenient, which can make the iron & measurement and abnormal lying more accurate and miscellaneous, and enter the printed circuit board. Efficient and high-quality f' secrets are actually suitable for women, ideality and progress, and the unprecedented _ circuit board drilling machine broken needle inspection position improvement. In order to make the Responsibility Review Committee (4) have a more advanced 9 M335908 solution and approval in the purpose of this creation, the following is a detailed description of the drawings and examples: [Embodiment] First, please refer to the fourth , Wuqi ^ 本创粒要_(4) The pressure foot 10 of the spindle lifting mechanism 1 of the circuit board drilling machine is in a state of forming a conduction loop with the grounded machine member in advance, and the conduction circuit is driven by the wire lifting mechanism.
