Description

Technical Field

[0001] The invention relates to an alloy resistor particle classification device, in particular to an alloy resistor particle classification device, an alloy resistor production process, and an alloy resistor. Background Art

[0002] Figure 1 The alloy resistor strip material 20 includes a resistor body 21, and an ink layer 22 and an epoxy resin layer 23 attached to both sides of the resistor body 21. The alloy resistor strip material 20 is a semi-finished product in the resistor production process and needs to be divided through a granulation process to form an alloy resistor.

[0003] The existing granulation process mainly uses punching to punch out the alloy resistor strip 20. The alloy resistor strip 20 is transferred to the punching equipment, and the traction mechanism is used to drive the strip to feed intermittently, so that the end of the strip enters under the punch, and the punch drops and punches the alloy resistor strip 20 when the feeding action stops. However, the above granulation method has the following problems:

[0004] 1. The stamping process easily causes burrs on the cross section of the alloy resistor strip material 20, making the size of the resulting alloy resistor particles uneven;

[0005] 2. Intermittent stamping is adopted, and each stamping action needs to wait for the punch to be reset, and only a single alloy resistance strip material 20 is subjected to granulation operation each time, resulting in low granulation efficiency. Summary of the invention

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an alloy resistor grading device, an alloy resistor production process, and an alloy resistor to improve the grading efficiency during the alloy resistor production process and to improve the dimensional accuracy of the alloy resistors obtained by grading.

[0007] The objective of the present invention is achieved through the following technical solutions:

[0008] An alloy resistor particle sorting device comprises: a cutter, a base, a pressing plate and an upper cover;

[0009] The base is provided with an inner cavity and a plurality of first avoidance grooves connected with the inner cavity, the pressing plate is located in the inner cavity, the pressing plate comprises a main body, a plurality of bearing parts and a plurality of second avoidance grooves, the first avoidance grooves are aligned with the second avoidance grooves, the plurality of bearing parts cooperate to carry the alloy resistance strip material to be granulated, and the main body cooperates with the inner cavity to extrude the alloy resistance strip material;

[0010] The upper cover is covered on the base, and the upper cover is provided with a plurality of tool alignment grooves, and the tool alignment grooves are connected with the first avoidance grooves;

[0012] In one of the embodiments, a plurality of auxiliary bosses are disposed in the inner cavity, and the auxiliary bosses and the bearing portions are alternately distributed.

[0013] In one of the embodiments, a copper gasket is provided at a position on the main body that contacts the alloy resistance strip material and a position on the inner cavity that contacts the alloy resistance strip material.

[0014] In one embodiment, the length of the copper gasket is greater than the length of the alloy resistor strip material.

[0015] In one embodiment, the thickness of the copper gasket is greater than the thickness of the alloy resistor strip material, and a sliding area and multiple cutting areas are provided on the copper gasket. Grooves are provided at the junction of the bearing portion and the main body and at the end of the bearing portion. Two copper gaskets are spaced apart on the bearing portion, and the sliding area is located in the groove, and each of the second avoidance grooves faces one of the cutting areas.

[0016] In one of the embodiments, a discharge port communicating with the inner cavity is provided on the base.

[0017] In one of the embodiments, an anti-drift strip is further included. The anti-drift strip is located on a side of the base away from the upper cover, and the anti-drift strip is abutted against the bearing portion.

[0018] In one of the embodiments, a machine screw is provided on the base, and the machine screw is used to push the pressing plate.

[0019] A production process of alloy resistors is implemented based on the above alloy resistor particle classification device, comprising the following steps:

[0020] Separate the upper cover from the base, remove the upper cover, and stack the alloy resistor strips to be granulated one by one on the bearing part of the pressing plate. When stacking the alloy resistor strips, make the alloy resistor strips parallel to the main body, and there are gaps between the alloy resistor strips.

[0021] Push the pressing plate to make the main body and the cavity wall of the inner cavity cooperate to clamp the alloy resistance strip material, so that the various alloy resistance strip materials on the bearing part are close to each other;

[0022] After the upper cover is covered, the knife groove, the first avoidance groove and the second avoidance groove are aligned, and the three are connected to form a channel. At this time, the part of the alloy resistor strip material located in the channel is the part to be cut;

[0023] Perform the knife setting operation, so that the saw blade on the cutter can be extended into the knife setting groove, start the cutter, the saw blade starts to rotate, and the cutter is translated along the extension direction of the knife setting groove. During the translation of the cutter, the saw blade contacts the alloy resistance strip material and cuts it off;

[0024] After the cutter moves from one end of the knife groove to the other end, the cutter starts to move horizontally along the long side direction of the main body, aligns the saw blade with the part of the alloy resistor strip material that has not been pelletized, and moves horizontally along the extension direction of the knife groove again to perform pelletizing action, repeating the above action until the saw blade passes through all the knife grooves;

[0025] Open the upper cover and take out the alloy resistance particles.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0050] See also Figure 2 and Figure 4 The present invention provides an alloy resistor particle classification device 10, which includes: a cutter 100, a base 200, a pressing plate 300 and an upper cover 400.

[0051] See also Figure 5 and Figure 6 The base 200 is provided with an inner cavity 210 and a plurality of first avoidance grooves 220 communicating with the inner cavity 210;

[0052] See also Figure 7 , Figure 8 and Fig. 9 The pressing plate 300 is located in the inner cavity 210. The pressing plate 300 includes a main body 310, a plurality of bearing parts 320 and a plurality of second avoidance grooves 330. The first avoidance groove 220 is aligned with the second avoidance groove 330. The plurality of bearing parts 320 are spaced apart along the extension direction of the long side of the main body 310. When the alloy resistor strip 20 is placed, the alloy resistor strip 20 is parallel to the main body 310. The plurality of bearing parts 320 jointly support the alloy resistor strip 20, and a plurality of alloy resistor strips 20 can be placed on the bearing parts 320 at the same time. Pushing the pressing plate 300 can clamp the alloy resistor strips 20, so that the plurality of alloy resistor strips 20 located on the bearing parts 320 are close to each other.

[0053] See also Figure 2 and Figure 3 The upper cover 400 covers the base 200 to prevent the alloy resistor strip material 20 from jumping when the cutter 100 tries to cut the pellets. The upper cover 400 is provided with a plurality of knife alignment grooves 410, which are connected to the first avoidance groove 220;

[0054] See also Figure 2 and Figure 3 The cutter 100 is provided with a plurality of saw blades 110, and the saw blades 110 pass through the knife groove 410 for cutting the alloy resistor strip material. The spacing between the saw blades 110 is consistent with the spacing between the knife grooves 410. When the cutter 100 is started, the saw blades 110 rotate and drive the saw blades 110 to translate along the extension direction of the knife groove 410, that is, the saw blades 110 move from one end of the knife groove 410 to the other end, and the saw blades 110 cut off each alloy resistor strip material 20 on the pressing plate 300 during the movement.

[0055] See also Fig. 9 It should be emphasized that the extension direction of the blade groove 410, the first avoidance groove 220 and the second avoidance groove 330 is perpendicular to the extension direction of the alloy resistor strip material 20. When the cutter 100 performs the dicing operation, the saw blade 110 moves along the extension direction perpendicular to the alloy resistor strip material 20 and cuts off each alloy resistor strip material 20 one by one during the movement.

[0056] See also Figures 9 to 12 , the process of implementing the pelletizing operation is as follows:

[0057] First, separate the upper cover 400 from the base 200. After removing the upper cover 400, stack the alloy resistor strip materials 20 to be granulated one by one on the bearing portion 320 of the pressing plate 300. When stacking the alloy resistor strip materials 20, make the alloy resistor strip materials 20 parallel to the main body 310. At this time, there are gaps between the alloy resistor strip materials 20. The distribution state of the alloy resistor strip materials 20 on the bearing portion 320 is as shown in FIG. Fig.10 As shown;

[0058] The pressing plate 300 is pushed so that the main body 310 and the cavity wall of the inner cavity 210 cooperate to clamp the alloy resistance strip material 20, so that the alloy resistance strip materials 20 on the bearing part 320 are close to each other. Fig.12 As shown;

[0059] After the upper cover 400 is covered, the knife groove 410, the first avoidance groove 220 and the second avoidance groove 330 are aligned, and the three are connected to form a channel 31. At this time, the part of the alloy resistor strip material 20 located in the channel 31 is the part to be cut;

[0060] Perform a knife alignment operation, so that the saw blade 110 on the cutter 100 can be extended into the knife alignment groove 410, start the cutter 100, the saw blade 110 starts to rotate, and the cutter 100 is translated along the extension direction of the knife alignment groove 410. During the translation of the cutter 100, the saw blade 110 contacts the alloy resistance strip material 20 and cuts it off;

[0061] After the cutter 100 moves from one end of the knife groove 410 to the other end, the cutter 100 begins to move horizontally along the long side direction of the main body 310, aligns the saw blade 110 with the uncut part of the alloy resistor strip material 20, and moves horizontally along the extension direction of the knife groove 410 again to perform the cutting action, and repeats the above action until the saw blade 110 passes through all the knife grooves 410. Finally, the upper cover 400 is opened to take out the alloy resistor particles.

[0062] During the pelletizing process, the bearing portion 320 of the pressure plate 300 can carry multiple alloy resistor strips 20 at the same time, and pushing the pressure plate 300 can gather the multiple alloy resistor strips 20 together, and the main body 310 and the inner wall of the inner cavity 210 can jointly limit the horizontal freedom of the alloy resistor strips 20 so that they cannot move away from each other; the upper cover 400 and the bearing portion 320 cooperate to press the alloy resistor strip 20 to prevent the alloy resistor strip 20 from jumping when the saw blade 110 is cutting, thereby ensuring the pelletizing accuracy.

[0063] The alloy resistance particle classification device 10 has the following advantages:

[0064] 1. When clamping, a plurality of alloy resistance strips are fixed at the same time by using a pressing plate 300, and a plurality of saw blades 110 are arranged on the cutter 100, so that a single feed can cut multiple parts of the strip, thereby greatly improving the pelletizing efficiency;

[0065] 2. The alloy resistor strip is cut by the saw blade 110 to reduce the impact of the strip on the strip during the granulation process, and burrs are not easily generated, so that the cutting surface is flat and uniform. Before cutting, the pressure plate 300 in the inner cavity 210 limits the horizontal freedom of the strip, and the upper cover 400 covers the strip, exposing only the part to be cut on the strip, preventing the strip from shifting during the granulation process, thereby improving the granulation accuracy.

[0066] See also Fig.10 and Fig.12 As can be seen from the above pelletizing process, when clamping the alloy resistor strip 20, it is necessary to push the pressing plate 300 so that the main body 310 and the cavity wall of the inner cavity 210 cooperate to clamp the alloy resistor strip 20. This process will bring the alloy resistor strips 20 together, and each alloy resistor strip 20 is subjected to extrusion force. The alloy resistor strip 20 includes a resistor body 21, and an ink layer 22 and an epoxy resin layer 23 attached to both sides of the resistor body 21. When the alloy resistor strip 20 is subjected to excessive pressure, the ink layer 22 is easily crushed, and a concave surface is pressed out on the epoxy resin layer 23, that is, the pressure exerted by the pressing plate 300 on the alloy resistor strip 20 is too large, which can easily damage the product. To solve this problem, a copper gasket 500 is provided at the position on the main body 310 that contacts the alloy resistor strip and at the position on the inner cavity 210 that contacts the alloy resistor strip 20. Since copper is soft, when the thrust of the pressing plate 300 is too large, the copper gasket 500 is first dented. The copper gasket 500 is used as a buffer to avoid crushing the product during the clamping process.

[0067] It should be noted that the addition of the copper gasket 500 can avoid crushing the product when clamping the alloy resistor strip 20, but the copper gasket 500 is placed at the position on the main body 310 that contacts the alloy resistor strip and at the position on the inner cavity 210 that contacts the alloy resistor strip 20. In fact, the copper gasket 500 is also clamped between the inner wall of the main body 310 and the inner cavity 210. Therefore, the copper gasket 500 will be cut off together during the pelletizing operation. When cutting, the granular copper gasket 500 is mixed with the alloy resistor particles. The copper gasket 500 particles need to be sorted out in the subsequent workstation, which reduces the production efficiency of the alloy resistor, and each pelletizing action requires the consumption of 2 copper gaskets 500, and the resulting copper gasket 500 particles are non-target products, which increases the production cost of the alloy resistor.

[0068] See also Figure 7 and Fig.13 To solve the above problems, the present application also makes the following improvements to the copper gasket 500 and the pressing plate 300:

[0069] The length of the copper gasket 500 is greater than the length of the alloy resistance strip material 20. The thickness of the copper gasket 500 is greater than the thickness of the alloy resistance strip material, and the copper gasket 500 is provided with a sliding area 510 and a plurality of cutting areas 520. The copper gasket 500 is in the shape of a rectangular parallelepiped, wherein Fig.13 The area circled by the inner dotted line is the cutting area 520 .

[0070] A groove 340 is formed at the junction of the bearing portion 320 and the main body 310 and at the end of the bearing portion 320 . Two copper washers 500 are spaced apart on the bearing portion 320 . The sliding area 510 is located in the groove 340 . Each second avoidance groove 330 faces a cutting area 520 .

[0071] See also Fig. 9 A machine screw 250 is provided on the base 200 , and the machine screw 250 is used to push the pressing plate 300 .

[0072] See also Fig.10 and Fig.14 Before clamping the alloy resistor strip material 20, a copper gasket 500 is placed on each end of the main body 310 and the bearing part 320 close to the inner cavity 210, and the sliding area 510 on the copper gasket 500 is sunk into the groove 340 at its position. At this time, the cutting area 520 is located in the channel 31 formed by the knife groove 410, the first avoidance groove 220 and the second avoidance groove 330. Therefore, when the saw blade 110 passes through the channel 31, the cutting area 520 will be cut together with the alloy resistor strip material 20 to form an incision 32, but the sliding area 510 sunk into the groove 340 does not contact the saw blade 110, so the copper gasket 500 will not be directly cut off;

[0073] See also Fig.15 and Fig.16 After the pelletizing operation is completed, the copper gasket 500 will not be cut off. The next batch of alloy resistor strip materials 20 to be pelletized are placed between the two copper gaskets 500, and the copper gasket 500 is pushed to slide along the long side direction of the main body 310, so that the incision 32 and the channel 31 are staggered. When the pelletizing operation is performed, the saw blade 110 will leave another incision 32 in the cutting area 520. Similarly, each time a pelletizing operation is performed, the copper gasket 500 is pushed to slide once, so that the copper gasket 500 can be reused until the cutting area 520 is full of incisions 32, and then replaced with a new copper gasket 500.

[0074] It should be noted that the length of the copper gasket 500 is greater than the length of the alloy resistor strip 20, and the thickness of the copper gasket 500 is greater than the thickness of the alloy resistor strip. The sliding area 510 on the copper gasket 500 is sunk into the groove 340, and the saw blade 110 cannot contact the sliding area 510 during the pelletizing operation, thereby ensuring that the copper gasket 500 will not be cut off, allowing the copper gasket 500 to be reused, which can reduce the loss of the copper gasket 500 in the pelletizing process and reduce the production cost of the alloy resistor.

[0075] Furthermore, after optimization, the copper gasket 500 will not be cut directly, thus avoiding the problem of the copper gasket 500 particles and the alloy resistor particles being mixed together during the pelletizing process, and no additional station is required to sort the intermediate products; the production process of the alloy resistor is shortened, which is conducive to improving its production efficiency;

[0076] It should be emphasized that when cutting, the saw blade 110 feeds along the channel 31 formed by the blade groove 410, the first avoidance groove 220 and the second avoidance groove 330. The cutting process applies radial force to the alloy resistor strip material 20. Before each cutting, the copper gasket 500 is pushed to make the part without the incision 32 on the cutting area 520 close to the part to be cut on the alloy resistor strip material 20 to prevent the alloy resistor strip material 20 from radial displacement and deformation during the cutting process, so as to ensure the flatness of the cutting surface and improve the size accuracy of the alloy resistor particles obtained by cutting.

[0077] See also Figure 4 In one embodiment, the cutter 100 is further provided with a protective cover 120 to prevent the debris generated during the pelletizing process from splashing outside the device.

[0078] In one embodiment, a pin (not shown) is provided between the base 200 and the upper cover 400 , and the matching accuracy between the upper cover 400 and the base 200 is improved by the pin.

[0079] See also Figure 6In one embodiment, a discharge port 240 communicating with the inner cavity 210 is provided on the base 200, and the debris generated during the pelletizing process can be discharged through the discharge port 240, which is convenient for centralized cleaning.

[0080] See also Figure 4 In one embodiment, the alloy resistor particle classification device 10 further includes an anti-drift strip 600, which is located on a side of the base 200 away from the upper cover 400, and the anti-drift strip 600 abuts against the bearing portion 320. The anti-drift strip 600 provides support for the pressing plate 300 in the inner cavity 210 to prevent the bearing portion 320 from deflecting.

[0081] See also Figure 5 Preferably, a plurality of auxiliary bosses 230 are provided in the inner cavity 210 , and the auxiliary bosses 230 and the bearing parts 320 are alternately distributed. The auxiliary bosses 230 and the bearing parts 320 jointly bear the alloy resistor strip material 20 .

[0082] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
