下面参照图1至图8描述根据本公开一些实施例所述的激光调阻机。Hereinafter, the laser trimmer according to some embodiments of the present disclosure will be described with reference to FIGS. 1 to 8.

本公开提供了一种激光调阻机，如图1至图7所示，包括激光切割头1、第一多轴导轨2和治具3；治具3配置成固定待调阻的电阻；激光切割头1与第一多轴导轨2相连接，第一多轴导轨2能够带动激光切割头1在三维空间内运动，使激光切割头1能够移动至位于治具3上的电阻的上方，以对电阻进行切割调阻。换句话说，第一多轴导轨2能够带动激光切割头1在三维空间内运动，从而带动激光切割头1相对于位于治具3上的电阻运动，以对电阻进行切割，切割后的电阻的阻值能够发生改变，从而通过切割实现对电阻的调阻。The present disclosure provides a laser resistance trimming machine, as shown in Figures 1 to 7, comprising a laser cutting head 1, a first multi-axis guide rail 2 and a fixture 3; the fixture 3 is configured to fix the resistance to be trimmed; laser The cutting head 1 is connected to the first multi-axis guide rail 2. The first multi-axis guide rail 2 can drive the laser cutting head 1 to move in the three-dimensional space, so that the laser cutting head 1 can move to above the resistance on the jig 3 to Cut and adjust the resistance. In other words, the first multi-axis guide rail 2 can drive the laser cutting head 1 to move in a three-dimensional space, thereby driving the laser cutting head 1 to move relative to the resistance located on the jig 3 to cut the resistance. The resistance value can be changed, so that the resistance can be adjusted by cutting.

本公开提供的激光调阻机包括激光切割头1、第一多轴导轨2和治具3；在对电阻进行切割调阻时，电阻放置于治具3的操作台上，治具3能够对放置于其上的电阻进行固定，防止其在切割过程中发生移动，影响切割调阻的精度和准确性。同时，治具3还能够解除对电阻的固定，从而在不进行电阻切割时将电阻从治具3上取下，以及便于更换新的电阻。The laser trimming machine provided by the present disclosure includes a laser cutting head 1, a first multi-axis guide rail 2 and a fixture 3. When cutting and trimming the resistor, the resistor is placed on the operating table of the fixture 3, and the fixture 3 can The resistor placed on it is fixed to prevent it from moving during the cutting process and affect the precision and accuracy of cutting resistance. At the same time, the fixture 3 can also release the fixing of the resistor, so that the resistor can be removed from the fixture 3 when the resistance cutting is not performed, and it is convenient to replace a new resistor.

在对金属材料的电阻进行激光切割调阻时，可以采用高功率的激光，高功率的激光穿透力强，可以配备激光切割头1，通过激光切割头1发出的激光束来对电阻进行切割；且由于激光功率高，无法利用振镜来控制激光束移动；因此，本公开通过直接移动激光切割头1至待调阻的电阻处来对电阻进行切割调阻。When performing laser cutting and resistance adjustment on the resistance of metal materials, high-power lasers can be used. The high-power lasers have strong penetrating power and can be equipped with a laser cutting head 1. The laser beam emitted by the laser cutting head 1 can cut the resistance ; And because the laser power is high, the galvanometer cannot be used to control the movement of the laser beam; therefore, the present disclosure directly moves the laser cutting head 1 to the resistor to be adjusted to cut and adjust the resistance.

激光切割头1能够发出高功率的激光束；激光切割头1位于第一多轴导轨2上，第一多轴导轨2的X轴导轨、Y轴导轨和Z轴导轨共同限定出一个三维空间，第一多轴导轨2能够带动激光切割头1在该三维空间内运动，也即第一多轴导轨2能够带动激光切割头1在x轴、y轴和z轴的方向上运动；治具3位于该三维空间内，因此在将待调阻的电阻固定在治具3上后，第一多轴导轨2能够带动激光切割头1移动至位于治具3上的电阻的上方，并进一步精确调整激光切割头1的位置，使激光切割头1移动至待调阻的电阻需要进行激光切割的位置，然后开启激光切割头1使其发出激光束，对电阻进行激光切割调阻。在完成一次切割调阻后，可以继续移动激光切割头1至下一处需要切割的位置继续切割调阻的工作。从而，可以根据金属电阻需要切割的不同位置，依次移动激光切割头1的位置，完成对其的阻值调整；并且通过第一多轴导轨2能够快速和精确地移动激光切割头1至指定位置，对激光切割头1进行快速和精确定位，从而提高调阻的精度和效率。The laser cutting head 1 can emit a high-power laser beam; the laser cutting head 1 is located on the first multi-axis guide 2, and the X-axis guide, Y-axis guide and Z-axis guide of the first multi-axis guide 2 jointly define a three-dimensional space. The first multi-axis guide rail 2 can drive the laser cutting head 1 to move in the three-dimensional space, that is, the first multi-axis guide rail 2 can drive the laser cutting head 1 to move in the x-axis, y-axis and z-axis directions; fixture 3 Located in the three-dimensional space, so after fixing the resistor to be adjusted on the fixture 3, the first multi-axis guide 2 can drive the laser cutting head 1 to move above the resistor on the fixture 3, and further accurately adjust The position of the laser cutting head 1 moves the laser cutting head 1 to the position where the resistance to be adjusted requires laser cutting, and then the laser cutting head 1 is turned on to emit a laser beam to perform laser cutting and resistance adjustment on the resistance. After finishing a cutting and adjusting resistance, you can continue to move the laser cutting head 1 to the next position to be cut to continue cutting and adjusting resistance. Therefore, the position of the laser cutting head 1 can be moved in sequence according to the different positions where the metal resistance needs to be cut to complete the resistance adjustment; and the laser cutting head 1 can be quickly and accurately moved to the specified position through the first multi-axis guide 2 , The laser cutting head 1 is quickly and accurately positioned, thereby improving the precision and efficiency of resistance adjustment.

请参阅图6，可选的，治具3的操作台上形成有压件31，压件31的数量可以为两个，两个压件31间隔相对设置，通过两个压件31能够分别对电阻宽度方向的两侧进行压制，以对操作台上的电阻进行固定；且每个压件31均与一个升降驱动装置的活动端相连接，通过升降驱动装置能够驱动压件31的升降。当需要将电阻放置于治具3的操作台上时，先通过升降驱动装置驱动两个压件31向远离治具3的操作台的方向运动，使压件31与操作台之间具有间距以形成夹持空间，然后将电阻从一侧置入操作台和压件31之间，然后再次通过升降驱动装置驱动使两个压件31向靠近操作台的方向运动，使夹持空间缩小，利用压件31将电阻压紧于压件31和操作台之间，从而将电阻稳固地压制在治具3上，防止其在调阻过程中发生窜动，影响调阻的精度和效率。Referring to FIG. 6, optionally, a pressing piece 31 is formed on the operating table of the jig 3, and the number of pressing pieces 31 can be two. The two pressing pieces 31 are arranged opposite to each other. The two sides in the width direction of the resistance are pressed to fix the resistance on the operating table; and each pressing member 31 is connected to a movable end of a lifting driving device, and the lifting driving device can drive the lifting of the pressing member 31. When the resistance needs to be placed on the operating table of the fixture 3, the two pressing pieces 31 are first driven to move away from the operating table of the fixture 3 through the lifting drive device, so that the pressing piece 31 and the operating table have a distance between them. The clamping space is formed, and then the resistance is inserted between the operating table and the pressing piece 31 from one side, and then the two pressing pieces 31 are driven by the lifting drive device to move closer to the operating table to reduce the clamping space and use The pressing piece 31 presses the resistor between the pressing piece 31 and the operating table, thereby firmly pressing the resistor on the jig 3 to prevent it from moving during the resistance adjustment process, which affects the accuracy and efficiency of the resistance adjustment.

显然，还可以通过设置一个升降驱动装置来同时控制两个压件31的升降运动。Obviously, it is also possible to control the lifting movement of the two pressing members 31 at the same time by setting a lifting drive device.

此外，压件31的数量可以不限于是两个，还可以是一个、三个或者四个等。In addition, the number of pressing members 31 may not be limited to two, and may also be one, three, or four.

And after the resistance adjustment operation is completed, the material picking and discharging mechanism 5 can be used to remove the resistance that has been adjusted from the jig 3.

在进行激光调阻作业前，可以将一定数量的需要调阻的电阻装填于料仓4内，然后通过取放料机构5依次逐个将待调阻的电阻移动至治具3上进行调阻，从而提高工作效率，降低操作人员的劳动强度。Before the laser trimming operation, a certain number of resistors that need to be trimmed can be loaded into the silo 4, and then the resistors to be trimmed are moved to the fixture 3 one by one through the picking and unloading mechanism 5. Thereby improving work efficiency and reducing the labor intensity of operators.

可选的，一定数量待调阻的电阻可以以层叠的方式排布，取放料机构5从上至下依次取出电阻。Optionally, a certain number of resistors to be adjusted can be arranged in a layered manner, and the material taking and discharging mechanism 5 takes out the resistors in order from top to bottom.

在本公开中，如图2和图3所示，料仓4内间隔设置有上料部41和下料部42；上料部41和下料部42均包括料盘43和升降装置44，其中料盘43配置成放置电阻，可选的，上料部41的料盘43配置成放置调阻前的电阻，下料部42的料盘43配置成放置调阻后的电阻。上料部41和下料部42的料盘43均与各自的升降装置44相连接，升降装置44配置成驱动料盘43升降，从而提升或者降低电阻的高度。In the present disclosure, as shown in Figs. 2 and 3, the silo 4 is provided with a feeding part 41 and a feeding part 42 at intervals; the feeding part 41 and the feeding part 42 each include a feeding tray 43 and a lifting device 44, The tray 43 is configured to place a resistor. Optionally, the tray 43 of the loading part 41 is configured to place the resistor before adjusting the resistance, and the tray 43 of the feeding part 42 is configured to place the resistance after adjusting the resistance. The trays 43 of the loading part 41 and the unloading part 42 are both connected to their respective lifting devices 44, and the lifting devices 44 are configured to drive the trays 43 up and down, thereby increasing or reducing the height of the resistance.

具体使用时，当需要取出料仓4内的位于上料部41上的待调阻的电阻时，可以通过上料部41的升降装置44驱动上料部41的料盘43上升，使位于其上的电阻到达料仓4的敞口端，从而方便取放料机构5取出位于上料部41内的电阻；位于治具3上的调阻后的电阻需要通过取放料机构5放回料仓4的下料部42进行存放时，可以先将利用下料部42的升降装置44驱动下料部42对应的料盘43升起至敞口端，利用取放料机构5将调阻后的电阻放置于料盘43上后，再利用升降装置44使料盘43下降回料仓4内。如此设置，电阻能够收纳至料仓4中，电阻不易被污染，且电阻没有凸出料仓4，不会干扰电阻的调阻作业。In specific use, when the resistance to be adjusted on the loading portion 41 in the silo 4 needs to be taken out, the lifting device 44 of the loading portion 41 can be used to drive the tray 43 of the loading portion 41 to rise, so that it is located there. The resistance on the upper reaches the open end of the silo 4, so that it is convenient for the feeding and unwinding mechanism 5 to take out the resistance in the feeding part 41; the resistance adjusted on the jig 3 needs to be put back through the feeding and unwinding mechanism 5 When the blanking part 42 of the bin 4 is stored, the lifting device 44 of the blanking part 42 can be used to drive the feeding tray 43 corresponding to the blanking part 42 to the open end, and the feeding and unloading mechanism 5 is used to adjust the resistance. After placing the resistor of φ on the tray 43, the lifting device 44 is used to lower the tray 43 back into the bin 4. With this arrangement, the resistor can be stored in the silo 4, the resistor is not easily contaminated, and the resistor does not protrude from the silo 4, which will not interfere with the resistance adjustment operation of the resistor.
