Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of laser resistance adjustment, and in particular relates to a simple manual laser resistance adjustment platform. Background Art
[0002] The principle of laser resistance trimming is to use an extremely fine laser beam to hit the rod-shaped resistor, and cut the rod-shaped resistor by vaporizing and evaporating the resistor body. The laser beam cuts the rod-shaped resistor according to a computer preset program, and changes the resistance value of the resistor by changing the geometric shape of the rod-shaped resistor. As the laser cutting process proceeds, the real-time measurement circuit monitors the change in the resistance value of the rod-shaped resistor in real time, and the resistance value of the rod-shaped resistor continues to approach the target resistance value. When the rod-shaped resistor reaches the target resistance value, the laser beam is turned off, and the laser resistance trimming process is realized. The equipment for laser resistance trimming is called a laser resistance trimming platform or a laser resistance trimming machine.
[0003] With the widespread application of rod resistors, the products of rod resistors are gradually showing a trend of diversification, and the application of laser resistance trimming is also showing the characteristics of diversification, precision and automation. The construction cost of an automated laser resistance trimming production line is very high, and often requires companies to have a large-scale rod resistor production demand. Some companies have a small demand for rod resistor production and produce a large number of rod resistor models. For this reason, the construction of an automated laser resistance trimming production line is costly and has a low utilization rate. Generally, companies are unwilling to invest in the construction of automated production lines, but have actual production needs, so they can only choose manual laser resistance trimming machines. The existing manual laser resistance trimming machines have a relatively complex structure. Before production personnel can actually use the manual laser resistance trimming machines, they need a long period of learning and training, which increases the economic burden of the company and also affects production efficiency.
[0004] In summary, there is an urgent need for a laser resistance trimming platform that is low-cost, suitable for rod resistors of different specifications, and easy to operate. Utility Model Content

At this time, the V-shaped groove 1011 at the front end of the clamping positioning plate 108 presses the upper part of the rod-shaped resistor 11; then the PLC control module sends a control command to the servo motor of the synchronous moving device 6 The servo motor 66 sends a control command to start the rotation.

The servo motor 66 stops rotating. At this time, the left and right rotating electrodes 76 tighten the rod-shaped resistor 11. At this time, the CCD visual camera 5 obtains The position signal of the rod-shaped resistor 11 is transmitted to the PLC control module, and the PLC control module sends a start control instruction to the laser emitting device 3.

At this time, the V-shaped groove 1011 at the front end of the clamping positioning plate 108 presses the upper part of the rod-shaped resistor 11; on the one hand, the rod-shaped resistor 11 is pressed tightly, and on the other hand, the upper part of the rod-shaped resistor 11 is pressed; under the joint action of the two, the fixed clamping effect of the rod-shaped resistor 11 is realized.
[0021] The main purpose of setting up the synchronous moving device 6 and the clamping device 10 is: under the joint cooperation of the synchronous moving device 6 and the clamping device 10, on the one hand, the rod-shaped resistor 11 can be fixed and clamped in the radial direction, and on the other hand, the rod-shaped resistor 11 can be synchronously pressed in the axial direction; under the joint action, the stability of the fixed clamping and the top clamping of the rod-shaped resistor 11 is improved, and the resistance adjustment accuracy of the rod-shaped resistor 11 is improved.

At this time, the left and right rotating electrodes 76 tighten the rod-shaped resistor 11. On the one hand, it plays a tightening role in the axial direction of the rod-shaped resistor 11. On the other hand, when the laser adjustment resistance position of the rod-shaped resistor 11 needs to be rotated, the rotation of the servo motor 2 72 can be used to drive the coupling 2 73, the right rotating cylinder 75 and the right rotating electrode 76 to rotate, and at the same time drive the left rotating electrode 76 and the left rotating cylinder 75 to rotate synchronously, and finally rotate the rod-shaped resistor 11 to a certain angle.

The servo motor 2 72 starts to rotate, and the servo motor 2 72 drives the coupling 2 73, the right rotating cylinder 75 and the right rotating electrode 76 to rotate, and at the same time drives the left rotating electrode 76 and the left rotating cylinder 75 to rotate synchronously, and finally the rod-shaped resistor 11 is rotated by a certain angle.
