Description

Technical Field

[0001] The invention relates to the field of alloy resistor processing, in particular to an automatic polishing device for alloy resistor strip material and an alloy resistor production process. Background Art

[0002] Figure 1 It is a schematic diagram of the structure of the alloy resistor strip 20, which includes a resistor body 21 and a conductor 22 located on both sides of the resistor body 21. The resistor body 21 and the conductor 22 are strips of two different materials. The junction between the resistor body 21 and the conductor 22 is a weld 23. The two raw materials are connected by welding. The alloy resistor strip 20 undergoes subsequent workstations such as pelletizing and resistance adjustment to obtain an alloy resistor.

[0003] It can be seen that during the welding process, bulges 24 will be formed at the location of the weld 23, and it is necessary to use a polishing machine to grind and eliminate these bulges 24 in order to improve the accuracy of subsequent processing. The alloy resistance strip material 20 is a slender strip material, which is soft and does not bear force. When the existing polishing equipment is used to grind the bulge 24, it is necessary to configure a positioning fixture to provide support for the alloy resistance strip material 20. In order to ensure the polishing quality, it is necessary to extend the contact time between the polishing wheel and the position to be polished, that is, it is necessary to limit the feeding speed of the alloy resistance strip material 20, and the polishing efficiency is low; On the other hand, in the existing polishing equipment, the direction of the force generated by the polishing wheel when grinding the alloy resistor strip 20 is either consistent with the feeding direction of the alloy resistor strip 20, or perpendicular to the feeding direction of the alloy resistor strip 20. When the first polishing method is used, the contact area between the polishing wheel and the bump 24 is small, and a longer polishing time is required; although the second polishing method can improve the polishing efficiency, the alloy resistor strip 20 is welded by three strips. When polishing in this way, the external force generated by the polishing wheel on the strip is easy to damage the weld 23, resulting in the separation of the resistor 21 and the conductor 22, and then resulting in defective alloy resistor strip 20.

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 of the related listed items.

[0021] See also Figure 3 and Figure 4 The present invention provides an automatic polishing device 10 for alloy resistance strip materials, which includes: a frame 100 and a polishing mechanism 200 located on the frame 100, a limiting roller 300, a slide table 400, and a winding disk 500.

[0022] See also Figure 5 , the alloy resistance strip material 20 is stored on the winding reel 500, and the end of the alloy resistance strip material 20 is fixed on the limiting roller 300; See also Figure 3 and Figure 4 The slide 400 is used to drive the winding disc 500 to translate along the extension direction of the axis of the limiting roller 300; See also Figure 4 and Figure 8 The polishing mechanism 200 is disposed toward the limiting roller 300 and is used for polishing the alloy resistance strip material 20 located on the limiting roller 300 .

[0023] Before polishing, the winding reel 500 is moved to one end of the limiting roller 300 through the slide 400, the alloy resistance strip 20 is pulled out from the winding reel 500, and the end of the alloy resistance strip 20 is fixed on the limiting roller 300. The slide 400 is started again to drive the winding reel 500 to move toward the other end of the limiting roller 300, so that the alloy resistance strip 20 is spread on the outer wall of the limiting roller 300, and then the polishing mechanism 200 polishes the alloy resistance strip 20 on the limiting roller 300.

[0024] During the above-mentioned polishing process, the limiting roller 300 provides support for the alloy resistance strip material, so that the polishing mechanism 200 can be in stable contact with the alloy resistance strip material 20, thereby ensuring the polishing quality and improving the polishing efficiency.

[0025] In the existing polishing equipment, the direction of the force generated by the polishing wheel when grinding the alloy resistor strip 20 is either consistent with the feeding direction of the alloy resistor strip 20 or perpendicular to the feeding direction of the alloy resistor strip. When the first polishing method is used, the contact area between the polishing wheel and the bump 24 is small, and a longer polishing time is required; although the second polishing method can improve the polishing efficiency, the alloy resistor strip 20 is welded by three strips. When polishing in this way, the external force generated by the polishing wheel on the strip is easy to damage the weld 23, causing the resistor 21 and the conductor 22 to separate, thereby causing the alloy resistor strip 20 to be defective.

[0026] See also Figure 6 , Figure 7 and Figure 8 To solve the above problems, in the present application, a winding motor 130 matching the limiting roller 300 is provided on the frame 100, and the winding motor 130 is used to drive the limiting roller 300 to rotate so that the alloy resistance strip material 20 is spirally wound on the limiting roller 300. At the same time, the polishing mechanism 200 is improved as follows: The polishing mechanism 200 includes a follower platform 210 , a polishing motor 220 , a bracket 230 , and a polishing belt 240 , a driving wheel 250 , a driven wheel 260 , and a tensioning wheel 270 located on the bracket 230 .

[0027] The driven wheel 260 and the tension wheel 270 are located on the side of the limiting roller 300 . The driven wheel 260 and the tension wheel 270 cooperate to drive the polishing belt 240 to contact the alloy resistance belt material 20 on the limiting roller 300 .

[0028] The polishing mechanism 200 also includes an adjustment handle 280 , which is rotatably disposed on the bracket 230 . The adjustment handle 280 is provided with a rotating shaft 281 matching the driven wheel 260 . The bracket 230 is provided with an arc-shaped avoidance groove 231 . The adjustment handle 280 is used to drive the rotating shaft 281 to slide along the arc-shaped avoidance groove 231 .

[0029] The frame 100 is provided with a belt transmission module 110 and a track 120 . The follower platform 210 is provided on the track 120 . The belt transmission module 110 is used to drive the follower platform 210 to reciprocate along the extension direction of the axis of the limiting roller 300 .

[0030] A vacuum cleaner 233 is provided on the bracket 230 , and the vacuum cleaner 233 faces the position where the polishing belt 240 contacts the alloy resistance belt material 20 . The vacuum cleaner 233 is used to absorb debris generated during the polishing process.

[0031] The outer walls of the driving wheel 250 , the driven wheel 260 and the tensioning wheel 270 are all provided with anti-slip stripes.

[0032] A clearance opening 232 is formed on the bracket 230 near the limiting roller 300 .

[0033] The specific working principle of the above structure is as follows: In the process that the slide 400 drives the winding reel 500 to move from one end of the limiting roller 300 to the other end, the winding motor 130 drives the limiting roller 300 to rotate, and the limiting roller 300 rotates to wind up the alloy resistance strip material 20. Since the winding reel 500 unwinds the alloy resistance strip material 20 while translating, the alloy resistance strip material 20 wound on the outer wall of the limiting roller 300 is in a spiral shape; While the limiting roller 300 is winding the alloy resistance belt material 20, the belt transmission module 110 pulls the follower platform 210 to slide along the track 120 to the position where the alloy resistance belt material 20 is wound. The polishing motor 220 is started, and the polishing belt 240 is driven to rotate through the driving wheel 250 to polish the alloy resistance belt material 20 spirally wound on the limiting roller 300. While the polishing belt 240 is grinding the bulge 24 at the position of the weld 23, the limiting roller 300 keeps rotating to ensure that all parts of the alloy resistance belt material 20 can contact the polishing belt 240.

[0034] It can be seen that the driven wheel 260 and the tension wheel 270 are located on the side of the limiting roller 300, so that the polishing belt 240 polishes the alloy resistance belt material 20 on the limiting roller 300 from the side. The positional relationship between the polishing belt 240 and the alloy resistance belt material 20 is as shown in FIG. Figure 8 As shown, the debris generated during the grinding process can be directed toward the ground, and a vacuum cleaner 233 is provided to generate negative pressure to suck away the debris, thereby preventing the debris from splashing out of the equipment and contaminating the workshop, and reducing the cleaning pressure.

[0035] See also Fig. 9Furthermore, since the polishing belt 240 approaches the limiting roller 300 from the side to polish the alloy resistance strip material 20 thereon, and the alloy resistance strip material 20 spirally wound on the limiting roller 300 is in a spiral shape, during the polishing process, there is an angle between the direction 31 of the force exerted by the polishing belt 240 on the alloy resistance strip material 20 and the extension direction 32 of the alloy resistance strip material 20, and the angle formed by the two is greater than 0° and less than 90°, that is, the moving direction of the polishing belt 240 is not along the extension direction of the weld 23, which is beneficial for the polishing belt 240 to grind the bulge 24 and improve the polishing efficiency.

[0036] It should be noted that the alloy resistor strip 20 is wound around the limiting roller 300 in circles, and the two adjacent circles of the alloy resistor strip 20 are attached to each other, so that the two adjacent circles of the alloy resistor strip 20 cannot move along the axis of the limiting roller 300, that is, the alloy resistor strip 20 provides a limit for itself, and there is no space for the resistor 21 and the conductor 22 to separate from each other. Therefore, even if the polishing belt 240 generates too much external force on the alloy resistor strip 20 during the grinding process, since the two adjacent circles of the alloy resistor strip 20 have no movable space, the resistor 21 and the conductor 22 also do not have a space to separate from each other, which can avoid the pulling force generated during the polishing process that causes the resistor 21 and the conductor 22 to separate. That is, the method of limiting the alloy resistor strip 20 on the limiting roller 300 eliminates the problem of the weld 23 being torn due to the excessive polishing force of the polishing belt 240. The operator can increase the rotation speed of the polishing belt 240 and reduce the distance between the polishing mechanism 200 and the limiting roller 300 as required to increase the polishing force, thereby improving the polishing efficiency of the alloy resistance belt material 20.

[0037] See also Figure 3 It can be seen that when the polishing belt 240 performs the polishing action, it is in contact with multiple circles of the alloy resistance strip material 20 on the limiting roller 300 at the same time, that is, the polishing belt 240 can polish multiple parts on the alloy resistance strip material 20 at the same time, which can effectively improve the polishing efficiency.

[0038] Furthermore, in the process that the belt transmission module 110 drives the follower platform 210 to translate along the track 120, the polishing belt 240 still keeps in contact with the polished portion of the alloy resistance belt material 20, thereby extending the polishing time of the polishing belt 240 on the alloy resistance belt material 20, as follows: See also Fig.10 and Fig.11 For the convenience of description, each circle of the alloy resistance strip 20 wound on the limiting roller 300 is referred to as a strip segment below. The direction indicated by the arrow in the figure is the moving direction of the polishing belt 240. Along the moving direction of the polishing belt 240 are strip segment 1, strip segment 2, strip segment 3, strip segment 4, and strip segment 5. The polishing belt 240 will polish the strip segment in contact with it.

[0039] exist Fig.10 In the state shown, the polishing belt 240 is in contact with the belt material segment 1, the belt material segment 2 and the belt material segment 3, and the polishing belt 240 performs a polishing operation on the above three belt material segments; Fig.10 Move the position shown to Fig.11 In the position shown, the polishing belt 240 is in contact with the belt segment 2, the belt segment 3 and the belt segment 4, wherein the belt segment 2 and the belt segment 3 have been in contact with and polished before the position of the polishing belt 240 changes, and continue to polish after the position of the polishing belt 240 changes, which is equivalent to extending the contact time between the alloy resistance belt 20 and the polishing belt 240, which is beneficial to improving the polishing quality.

[0040] See also Fig.11 and Fig.12 It should be emphasized that in the existing polishing equipment, the part of the polishing wheel 40 (or polishing belt) that contacts the alloy resistor strip material 20 is always the same contact surface 41, which will cause wear of the part in contact with the alloy resistor strip material 20 and reduce the polishing effect, and the polishing wheel 40 needs to be replaced frequently, while the parts of the polishing wheel 40 except the contact 41 are not utilized, and there is a problem of low utilization rate of consumables; in the present application, each strip segment can be moved from one end of the polishing belt 240 to the other end, and the strip segment will contact the entire strip surface of the polishing belt 240, and the entire strip surface participates in the polishing process of the alloy resistor strip material 20, which can improve the utilization rate of the polishing belt 240 and extend the service life of the polishing belt 240, and the polishing mechanism 200 can perform polishing operations for a long time, reduce the number of shutdowns to replace consumables, and thus improve polishing efficiency.

[0041] In summary, the automatic polishing device 10 for alloy resistance strip material provided by the present application has the following beneficial effects: 1. The polishing belt 240 polishes the alloy resistance belt material 20 on the limiting roller 300 from the side, so that the debris generated during the grinding process faces the ground, and is equipped with a vacuum cleaner 233. The vacuum cleaner 233 generates negative pressure to suck away the debris, which can prevent the debris from splashing out of the equipment and polluting the workshop, thereby reducing the cleaning pressure.

[0042] 2. The alloy resistance strip 20 wound on the limiting roller 300 is in a spiral shape, so that during the polishing process, there is an angle between the direction 31 of the force exerted by the polishing strip 240 on the alloy resistance strip 20 and the extension direction 32 of the alloy resistance strip 20, which is beneficial for the polishing strip 240 to grind the bulge 24 and improve the polishing efficiency.

[0043] 3. The alloy resistor strip 20 is wound around the limiting roller 300 in circles, so that two adjacent circles of the alloy resistor strip 20 cannot move along the axis of the limiting roller 300 to avoid the pulling force generated during the polishing process causing the resistor 21 and the conductor 22 to separate, to avoid excessive polishing force causing the weld 23 to be torn, and to reduce the generation rate of defective products during the polishing process.

[0044] 4. The polishing belt 240 can perform polishing operations on multiple locations on the alloy resistor strip material 20 at the same time, which can effectively improve the polishing efficiency.

[0045] 5. During the translation process, the polishing belt 240 will keep in contact with the polished part of the alloy resistor strip material 20, thereby extending the polishing time of the polishing belt 240 on the alloy resistor strip material 20, which is beneficial to improving the polishing quality.

[0046] 6. During the polishing process, the entire surface of the polishing belt 240 participates in the polishing process of the alloy resistor belt material 20, thereby improving the utilization rate of the polishing belt 240 and extending the service life of the polishing belt 240. The polishing mechanism 200 can also perform polishing operations for a long time, reducing the number of shutdowns to replace consumables, thereby improving polishing efficiency.

[0047] In one embodiment, a thread-shaped limiting stripe (not shown) is provided on the outer wall of the limiting roller 300, and the thread-shaped limiting stripe assists in winding the alloy resistor strip 20.

[0048] See also Figure 3 and Figure 4 In one embodiment, a winding motor 410 is provided on the slide 400, and the winding motor 410 is used to drive the winding reel 500 to rotate. When the polishing operation is implemented, the winding motor 410 drives the winding reel 500 to rotate forward, slowly unwinds the alloy resistance strip material 20, and assists the alloy resistance strip material 20 to spirally wind around the limiting roller 300; after the polishing operation is completed, the winding motor 410 starts to drive the winding reel 500 to rotate in the opposite direction, and at the same time, the slide 400 drives the winding reel 500 to return to the original path, and the two cooperate to wind up the alloy resistance strip material 20 on the limiting roller 300.

[0049] The present application also provides an alloy resistor production process, which is implemented by the above-mentioned automatic polishing device 10 for alloy resistor strip material, and includes the following steps: Step 1: welding the conductor 22 on both sides of the resistor 21 to obtain the alloy resistor strip material 20; Step 2: Winding the alloy resistance strip material 20 into a bundle and transferring it to the winding reel 500; Step 3: Pull out the alloy resistance strip material 20 from the winding reel 500 and fix the end of the alloy resistance strip material 20 on the limiting roller 300; Step 4: while driving the winding disk 500 to translate along the axis direction of the limiting roller 300, the limiting roller 300 is kept rotating, so that the alloy resistance strip material is spirally wound on the limiting roller 300; Step 5: Start the polishing motor 220 to allow the polishing belt 240 to polish the alloy resistance belt material on the limiting roller 300, and keep the limiting roller 300 rotating during the polishing process; Step 6: Rotate the limiting roller 300 in the opposite direction to remove the polished alloy resistance strip material 20; Step 7: pelletize, adjust resistance, and electroplate the polished alloy resistor strip 20 to obtain the target alloy resistor.

[0050] 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.
