Background

In the production process, the hanging rack for clamping the circuit board can be abnormal, such as hanging rack deformation, chuck dislocation and the like, which are not easy to find by operators in the use process, wherein the hanging rack deformation easily causes the uneven clamping of the circuit board, and causes the conditions of poor uniformity of electroplated matters on the surface of the circuit board, burning of edges and the like, and meanwhile, the deformed hanging rack also easily causes the problems of inaccurate positioning, other parts crashing and the like in the operation process, thereby causing serious accidents such as shutdown of the whole production line, scrapping of the whole cylinder board and the like. The deformation and dislocation of the clamping heads easily influence the conductivity and the clamping force of the hanging frames, and the poor conductivity can cause the mutual contention of current between the adjacent hanging frames, so that the electroplating effect of the circuit boards in the same batch is greatly different, and a large number of disqualification and rejection are caused; the hanger clamping force is reduced, so that the circuit board can fall in the electroplating process, the follow-up circuit board movement is affected, the circuit board is clamped and piled up, a large number of boards are scrapped, and the whole production line is stopped and the like.

In this embodiment, the puller 54 may be further connected to an external device in a communication manner, and at this time, a qualified preset value of the pulling force is preset in the external device, if the pulling force is greater than the preset value, the chuck 60 is proved to be qualified, and the manual working strength can be further reduced by judging the clamping force of the chuck 60 by the external device, so that misjudgment possibly caused by manual observation is avoided.

In some embodiments, the cartridge detection assembly 50 further includes a support member 55, the support member 55 is disposed on the frame 10, the support member 55 and the pinch-off element 51 are respectively located on opposite sides of the hanger 200, i.e. the support member 55 is disposed opposite to the pinch-off element 51, and when the hanger 200 moves beside the cartridge detection assembly 50, the hanger 200 is located between the pinch-off element 51 and the support member 55.

Because only a certain section of the hanger 200 is connected to the moving assembly 20, when the opening clamping element 51 extends out and abuts against the clamping head 60, the hanger 200 and the moving assembly 20 are not easy to provide support for the clamping head 60, and the hanger 200 is easy to shift or swing, and the supporting element 55 can provide support for the clamping head 60 when the opening clamping element 51 abuts against the clamping head 60, so as to avoid the hanger 200 from shifting or swinging.

The support element 55 may be a fixed structure, such as a platform, a bump, etc., and the support element 55 may be a telescoping element and move synchronously with the clamping element 51, such as a telescoping cylinder, etc.; further, the support member 55 is a cylinder.

In some embodiments, the collet detection assembly 50 further includes a circuit detection element, the circuit detection element is disposed on the rack 10, the circuit detection element is electrically connected to the spring 52, the circuit detection element is configured to detect a current or a resistance after the collet 60 clamps the spring 52, the collet 60 will supply power to the circuit board after clamping the circuit board, and the stability of the current will affect the consistency of the electroplating effect, if the conductivity of the collet 60 is poor, the current will be unstable, thereby causing a large difference in the electroplating effect and affecting the quality of the circuit board, and the circuit detection element can detect the current or the resistance after the collet 60 clamps the spring 52 and determine the stability of the current; the circuit detection element may be a resistive meter, an ammeter, or other electrical detection device.

It will be appreciated that the rack 10 is further provided with a conductive structure of the hanger 200, which is electrically connected to the chuck 60, and is also connected to an external power source, and the conductive structure of the hanger 200 is capable of supplying power to the chuck 60.

In some embodiments, the clamping elements 51 and the lifting elements 53 are telescopic cylinders, which may be, for example, electric, pneumatic, hydraulic or other telescopic cylinders; further, the clamping opening member 51 and the lifting member 53 are both cylinders.

In some embodiments, when there are two rows of clips 60 with different heights on the hanger 200, the hanger detecting apparatus 100 has two clip detecting assemblies 50, and the number of the clip opening members 51, the supporting members 55, the spring plates 52, the tensioner 54, and the lifting members 53 in each clip detecting assembly 50 corresponds to the number of clips 60 in the corresponding row; the two cartridge detection assemblies 50 may be disposed sequentially along the first direction of the housing 10.

It can be appreciated that in the hanger detecting apparatus 100 provided in the embodiment of the present utility model, the deformation detecting assembly 30, the displacement detecting assembly 40 and the two collet detecting assemblies 50 may be sequentially arranged along the first direction, or may be arranged according to the moving track of the moving assembly 20 driving the hanger 200; the relative positional relationship of the deformation detecting assembly 30, the displacement detecting assembly 40 and the collet detecting assembly 50 may be set according to other requirements and conditions such as the space in which the hanger detecting apparatus 100 is located.

The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model, and are intended to be included in the scope of the present utility model.
