[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1-4 As shown, a resistance measuring device for a double-row stamped frame includes:

[0027] The substrate 1 has a processing station 11 thereon, and the processing station 11 has a reference groove for positioning the resistor strip 5.

[0028] A pressing mechanism is disposed on the substrate 1. The pressing mechanism includes a pressing plate 3 and a pressing cover 4. The pressing cover 4 is used to press and position the processed resistor 6 on the resistor strip 5 in the reference groove. The pressing cover 4 is provided with a plurality of detection holes 42. The detection holes 42 are arranged opposite to the detection end of the processed resistor 6. The pressing plate 3 is used to press the frame 63 of the resistor strip 5 onto the substrate 1.

[0029] The frame 63 of the resistor strip 5 is provided with processing resistors 6 on both sides, and the processing resistors 6 are equally spaced on the frame 63.

[0030] The frame 63 of the resistor strip 5 of this invention has processing resistors 6 on both sides. After the resistor strip 5 is placed in the reference groove on the processing station 11 for positioning, the pressure plate 3 presses the frame 63 of the resistor strip 5 onto the substrate 1, and the pressure cover 4 presses and positions the processing resistors 6 on the resistor strip 5 in the reference groove. This can completely fix the resistor strip 5 product and the test point, and avoid the frame 63 from shaking due to machine shaking during resistance adjustment, which would cause the test point to shift and the resistance adjustment to be inaccurate. The detection hole 42 is set opposite to the detection end of the processing resistor 6. The detection elements such as probes of the detection equipment can pass through the detection hole 42 to quickly realize the resistance value detection of the processing resistor 6, which improves the convenience of detection.

[0031] The frame 63 of the resistor strip 5 is equipped with processing resistors 6 on both sides to form a double-row frame 63 design, which can also save materials and improve production efficiency.

[0032] In one embodiment of the present invention, the pressing cover 4 includes a plurality of cover plates 41, adjacent cover plates 41 are connected by a connecting component 43, the cover plate 41 is provided with a pressing groove that matches the processing resistor 6, the detection hole 42 is provided on the cover plate 41, and the detection hole 42 is connected to the pressing groove.

[0033] Specifically, adjacent cover plates 41 are connected by connecting components 43. The cover plates 41 are provided with pressure grooves that match the processing resistor 6, which completely fix the processed product and test points, and prevent the processing resistor 6 and frame 63 from shaking due to machine shaking during resistance adjustment. The probe passing through the detection device on the detection hole 42 can quickly detect the resistance value of the processing resistor 6, improving the convenience of detection.

[0034] In one embodiment of the present invention, the cover plate 41 is provided with an adjustment opening 83, which is used to expose the resistor body 61 of the processed resistor 6.

[0035] Specifically, by completely fixing the product and test points with the resistor strip 5, the opening 83 is adjusted to expose the resistor body 61 of the processed resistor 6, so as to avoid the frame 63 from shaking due to the machine shaking during resistance adjustment, which would cause the test points to shift.

The positioning pins are used to pass through the limiting holes 64 and the pin holes to position the frame 63 of the resistor strip 5.

[0037] Specifically, the frame 63 of the resistor strip 5 is set in the middle of the reference groove and is pressed onto the substrate 1 by the pressure plate 3. At the same time, the positioning pin on the pressure plate 3 passes through the limiting hole 64 and the pin hole to position the frame 63 of the resistor strip 5 and ensure the positioning accuracy of the resistor strip 5.

[0038] In one embodiment of the present invention, the connecting component 43 includes a connecting rod 44, the connecting rod 44 is provided with tapered heads 46 at both ends, the cover plate 41 is provided with a connecting hole 45 on its side, a rubber plug 47 is provided on the connecting hole 45, and the tapered head 46 is inserted into the rubber plug 47.

[0039] Specifically, a rubber plug 47 is provided on the connecting hole 45, and the conical head 46 is inserted into the insertion hole of the rubber plug 47. The connecting rod 44 can be quickly inserted and removed from the insertion hole, so that it can select the appropriate connecting part 43 for connection according to the specifications of the resistor strip 5, making it more convenient to use and maintain. At the same time, the rubber plug 47 is elastic, which provides a certain amount of wobbling allowance between adjacent cover plates 41, ensuring that each cover plate 41 moves to the corresponding processing fixture position, thereby improving processing efficiency.

[0040] In one embodiment of the present invention, the connecting component 43 includes a connecting nut 49 and two screws 48. The two screws 48 are respectively disposed on the sides of two adjacent cover plates 41. The two ends of the connecting nut 49 are respectively screwed into the two screws 48, and the threads of the two screws 48 are in opposite directions.

[0041] In one embodiment of the present invention, a fixing nut 491 is provided on the screw 48, and the screw 48 is fixedly connected to the connecting nut 49 by the fixing nut 491.

[0042] Specifically, the two ends of the connecting nut 49 are screwed into two screws 48 respectively. The threads of the two screws 48 are turned in opposite directions. By rotating the connecting nut 49, the distance between the two cover plates 41 connected to the screws 48 can be adjusted so that the appropriate connecting parts 43 can be selected for connection according to the specifications of the resistor strip 5. This method has a wide range of applications and is easy to adjust.

[0043] In one embodiment of the present invention, the reference groove is provided with a plurality of positioning fixtures for positioning a single processing resistor 6. The positioning fixture includes two positioning blocks 8, and a material support block 82 is provided between the two positioning blocks 8. The positioning blocks 8 are provided with fixture grooves 81 that match the electrodes 62 of the processing resistor 6. The material support block 82 is used to support the resistive body 61 of the processing resistor 6.

[0044] Specifically, the processing resistors 6 on both sides of the resistance band 5 are respectively placed on the corresponding processing fixtures. The electrodes 62 of the processing resistors 6 are placed in the fixture slots 81. The middle part of the resistor body 61 of the processing resistors 6 is supported by the material support block 82, which completely fixes the processed product and the test point, and avoids the processing resistors 6 and the frame 63 from shaking due to the machine shaking during resistance adjustment, thereby improving the processing accuracy.

[0045] In one embodiment of the present invention, a limiting component is further included. The limiting component includes two support plates 7, which are respectively disposed on both sides of the positioning fixture, and the processing resistor 6 or the pressure cover 4 is connected to the support surface of the support plate 7.

[0046] Specifically, the middle of the resistor body 61 of the processed resistor 6 is supported by the material support block 82, and part of the support surface of the support plate 7 on both sides supports the two sides of the resistor body 61. By supporting the resistor body 61 with the support plate 7, it is convenient to prevent deformation of the resistor body 61 when adjusting the resistance later, thus ensuring the processing quality of the resistor body 61. The edge of the cover plate 41 is connected to another part of the support surface of the support plate 7, which can support the middle of the cover plate 41, avoid deformation of the middle of the processed resistor 6 due to pressing, and improve the service life.

[0047] In one embodiment of the present invention, support blocks 12 are provided at the four corners of the bottom surface of the substrate 1. The support blocks 12 are frustum-shaped and have support holes.

[0048] Specifically, the frustum-shaped support block 12 can conveniently support the substrate 1 and position the substrate 1 on the processing table, which facilitates the quick placement of the resistor strip 5 on the device and improves work efficiency. The support holes on the support block 12 can ensure the positioning accuracy of the substrate 1 on the processing table and ensure the quality of subsequent processing.

[0049] Usage process

[0050] A resistor strip 5 with double-row processed resistors 6 is placed in a reference groove on a substrate 1. The frame 63 of the resistor strip 5 is located in the middle of the reference groove and is pressed onto the substrate 1 by a pressure plate 3. A positioning pin on the pressure plate 3 passes through a limiting hole 64 and a pin hole to position the frame 63 of the resistor strip 5. Simultaneously, the processed resistors 6 on both sides of the resistor strip 5 are placed onto corresponding processing fixtures. The electrodes 62 of the processed resistors 6 are placed in the fixture groove 81. The middle part of the resistor body 61 of the processed resistors 6 is supported by a material support block 82, and a portion of the support plates 7 on both sides supports the electrode. The resistor 61 is supported on both sides. According to the specifications of the resistor strip 5, a suitable connecting part 43 is selected for connection. The cover plate 41 on the pressing cover 4 is pressed onto the processed resistor 6 one by one. The edge of the cover plate 41 is connected to another part of the support surface of the support plate 7. The detection hole 42 is connected to the pressing groove, so that the detection end of the processed resistor 6 is exposed through the detection hole 42. The four test points of the processed resistor 6 are exposed on each cover plate 41. This can completely fix the product and the test points, and avoid the frame 63 from shaking due to the machine shaking during resistance adjustment, which would cause the test points to shift and the resistance adjustment to be inaccurate.
