Description

TECHNICAL FIELD

[0001] The present application relates to the field of alloy resistance processing, in particular to an automatic polishing equipment for alloy resistance strip and an alloy resistance production process. BACKGROUND

[0002] Figure 1 A structure diagram of the alloy resistance strip 20, which includes a resistance body 21 and a conductive body 22 located on both sides of the resistance body 21, the resistance body 21 and the conductive body 22 are two different material strips, the junction of the resistance body 21 and the conductive body 22 is a weld 23, and the two raw materials are connected by welding. The alloy resistance strip 20 can obtain the alloy resistance after subsequent workstations such as particle cutting, resistance processing.

[0003] It can be seen that a bulge 24 will be formed at the position of the weld 23 during the welding process, and the polishing machine needs to be used to polish and eliminate these bulges 24 in order to improve the accuracy of subsequent processing. The alloy resistance strip 20 is a long and thin strip material, which is soft and not stressed. When polishing the bulges 24 by using the existing polishing equipment, a positioning clamp needs to be configured to provide support for the alloy resistance strip 20. In order to ensure the polishing quality, the contact time between the polishing wheel and the position to be polished needs to be prolonged, that is, the feeding speed of the alloy resistance strip 20 needs to be limited, and the polishing efficiency is low.

[0004] On the other hand, in the existing polishing equipment, the direction of the force generated by the polishing wheel when polishing the alloy resistance strip 20 is either consistent with the feeding direction of the alloy resistance strip 20 or perpendicular to the feeding direction of the alloy resistance strip 20. When the first polishing method is used, the contact area between the polishing wheel and the bulge 24 is small, and a longer polishing time is needed. Although the second polishing method can improve the polishing efficiency, the alloy resistance strip 20 is welded by three strips, and the external force generated by the polishing wheel on the strip when polishing in this way is easy to damage the weld 23, causing the resistance body 21 and the conductive body 22 to separate, and further causing the alloy resistance strip 20 to be defective.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0045] Referring to Figure 3 and Figure 4 , the present application provides an automatic polishing equipment 10 for alloy resistance strips, which comprises a frame 100 and a polishing mechanism 200, a limiting roller 300, a sliding table 400, and a winding disc 500 located on the frame 100.

[0046] Referring to Figure 5The alloy resistance strip 20 is stored on the winding disc 500, and the end of the alloy resistance strip 20 is fixed on the limiting roller 300.

[0047] Please refer to Figure 3 and Figure 4 The sliding table 400 is used to drive the winding disc 500 to translate along the extension direction of the axis of the limiting roller 300.

[0048] Please refer to Figure 4 and Figure 8 The polishing mechanism 200 is arranged towards the limiting roller 300, and is used to polish the alloy resistance strip 20 on the limiting roller 300.

[0049] Before polishing, the winding disc 500 is moved to one end of the limiting roller 300 by the sliding table 400, the alloy resistance strip 20 is drawn out from the winding disc 500, and the end of the alloy resistance strip 20 is fixed on the limiting roller 300. The sliding table 400 is started again to drive the winding disc 500 to move towards the other end of the limiting roller 300, so that the alloy resistance strip 20 is laid on the outer wall of the limiting roller 300, and then the alloy resistance strip 20 on the limiting roller 300 is polished by the polishing mechanism 200.

[0050] In the above polishing process, the limiting roller 300 provides support for the alloy resistance strip, so that the polishing mechanism 200 can stably contact the alloy resistance strip 20, ensure the polishing quality, and improve the polishing efficiency.

[0051] In the existing polishing equipment, the direction of the force generated when the polishing wheel polishes the alloy resistance strip 20 is either consistent with the feeding direction of the alloy resistance strip 20 or perpendicular to the feeding direction of the alloy resistance strip. When the first polishing method is adopted, the contact area between the polishing wheel and the bulge 24 is small, and a longer polishing time is required. Although the second polishing method can improve the polishing efficiency, the alloy resistance strip 20 is welded by three strips, and the external force generated by the polishing wheel on the strip when the alloy resistance strip 20 is polished in this way can easily damage the weld 23, causing the resistance body 21 and the conductor 22 to separate, and further causing the alloy resistance strip 20 to be defective.

[0052] Please refer to Figure 6 , Figure 7 and Figure 8 To solve the above problems, in the present application, the winding motor 130 matched with the limiting roller 300 is arranged on the rack 100, and the winding motor 130 is used to drive the limiting roller 300 to rotate, so that the alloy resistance strip 20 is spirally wound on the limiting roller 300. At the same time, the following improvements are made to the polishing mechanism 200:

[0053] The polishing mechanism 200 comprises a follower platform 210, a polishing motor 220, a support 230, a polishing belt 240 on the support 230, a driving wheel 250, a driven wheel 260 and a tension wheel 270.

[0054] The driven wheel 260 and the tension wheel 270 are located on the side of the limiting roller 300, and the driven wheel 260 cooperates with the tension wheel 270 to drive the polishing belt 240 to contact the alloy resistance strip 20 on the limiting roller 300.

[0055] The polishing mechanism 200 further comprises an adjusting handle 280 rotatably arranged on the support 230, and the adjusting handle 280 is provided with a rotating shaft 281 matched with the driven wheel 260, and the support 230 is provided with an arc-shaped avoiding slot 231, and the adjusting handle 280 is used to drive the rotating shaft 281 to slide along the arc-shaped avoiding slot 231.

[0056] The rack 100 is provided with a belt transmission module 110 and a track 120, and the follower platform 210 is arranged on the track 120, and 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.

[0057] The support 230 is provided with a dust collector 233, and the dust collector 233 is located at the position where the polishing belt 240 contacts the alloy resistance strip 20, and the dust collector 233 is used to absorb the debris generated in the polishing process.

[0058] The outer wall of the driving wheel 250, the driven wheel 260 and the tension wheel 270 is provided with anti-skid stripes.

[0059] The support 230 is provided with an avoiding opening 232 near the limiting roller 300.

[0060] The specific working principle of the above structure is as follows:

[0061] In the process that the sliding table 400 drives the winding disc 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 the alloy resistance strip 20, and since the winding disc 500 winds the alloy resistance strip 20 while translating, the alloy resistance strip 20 wound on the outer wall of the limiting roller 300 is in a spiral shape;

[0062] When the limiting roller 300 winds the alloy resistance strip 20, the belt transmission module 110 drags the follow-up platform 210 to slide along the track 120 to the position where the alloy resistance strip 20 is wound. The polishing motor 220 is started, and the polishing belt 240 is driven to rotate by the driving wheel 250 to polish the alloy resistance strip 20 spirally wound on the limiting roller 300. The polishing belt 240 grinds the bulge 24 at the position of the weld 23 while the limiting roller 300 keeps rotating, ensuring that all parts of the alloy resistance strip 20 can contact the polishing belt 240.

[0063] It can be seen that the driven wheel 260 and the tensioning wheel 270 are located on the side of the limiting roller 300, so that the polishing belt 240 polishes the alloy resistance strip 20 on the limiting roller 300 from the side. The position relationship between the polishing belt 240 and the alloy resistance strip 20 is as shown in Figure 8 Thus, the debris generated in the grinding process can be directed towards the ground, and a dust collector 233 is arranged to generate negative pressure to suck away the debris, preventing the debris from splashing out of the equipment to contaminate the workshop and reducing the cleaning pressure.

[0064] Please refer to Figure 9 Further, since the polishing belt 240 approaches the limiting roller 300 from the side to polish the alloy resistance strip 20 thereon, and the alloy resistance strip 20 spirally wound on the limiting roller 300 is in a spiral shape, in the polishing process, the direction 31 of the force of the polishing belt 240 acting on the alloy resistance strip 20 and the extension direction 32 of the alloy resistance strip 20 form an angle, and the angle 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 to the grinding of the bulge 24 by the polishing belt 240 and improves the polishing efficiency.

[0065] It should be noted that the alloy resistance strip 20 is wound on the limiting roller 300 in turns, and the adjacent two turns of the alloy resistance strip 20 are in close contact with each other, so that the adjacent two turns of the alloy resistance strip 20 cannot move along the axis of the limiting roller 300, that is, the alloy resistance strip 20 provides its own limiting, and the resistance body 21 and the conductive body 22 do not have a space for mutual separation. Therefore, even if excessive external force is generated on the alloy resistance strip 20 during the grinding process of the polishing belt 240, since the adjacent two turns of the alloy resistance strip 20 do not have a movable space, and the resistance body 21 and the conductive body 22 do not have a space for mutual separation, the alloy resistance strip 20 can be prevented from being separated by the pulling force generated in the polishing process. That is, the alloy resistance strip 20 wound on the limiting roller 300 eliminates the problem that the weld 23 is torn due to excessive polishing force of the polishing belt 240. The operator can increase the rotating speed of the polishing belt 240, reduce the distance between the polishing mechanism 200 and the limiting roller 300, and thus increase the polishing force, thereby improving the polishing efficiency of the alloy resistance strip 20.

[0066] See Figure 3 It can be seen that when the polishing belt 240 performs the polishing action, it is in contact with multiple circles of 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.

[0067] Furthermore, while the belt transmission module 110 drives the follower platform 210 to translate along the track 120, the polishing belt 240 remains in contact with the polished portion of the alloy resistance strip material 20, thereby extending the polishing time of the polishing belt 240 on the alloy resistance strip material 20, as follows:

[0068] See also Figure 10 and Figure 11 For the convenience of description, each circle of alloy resistance strip 20 wound on the limiting roller 300 will be 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, there are strip segment 1, strip segment 2, strip segment 3, strip segment 4, and strip segment 5 in sequence. The polishing belt 240 will polish the strip segments that come into contact with it.

[0069] exist Figure 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; Figure 10 Move the position shown to Figure 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 it 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.

[0070] See also Figure 11 and Figure 12It 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. This will cause wear of the part in contact with the alloy resistor strip material 20 and a decrease in the polishing effect. The polishing wheel 40 needs to be replaced frequently, and the parts of the polishing wheel 40 other than the contact 41 are not utilized, resulting in a problem of low consumable utilization. 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. 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. 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.

[0071] In summary, the automatic polishing device 10 for alloy resistance strip provided in this application has the following beneficial effects:

[0072] 1. The polishing belt 240 polishes the alloy resistance strip material 20 on the limiting roller 300 from the side, so that the debris generated during the polishing process is directed toward the ground. A vacuum cleaner 233 is also provided to generate negative pressure to suck away the debris, thereby preventing the debris from splashing out of the equipment and contaminating the workshop, thereby reducing the cleaning pressure.

[0073] 2. The alloy resistance strip 20 wound on the limiting roller 300 is spirally shaped, 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.

[0074] 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, thereby avoiding the pulling force generated during the polishing process that causes the resistor body 21 and the conductor 22 to separate, and avoiding excessive polishing force that causes the weld 23 to be torn, thereby reducing the rate of defective products during the polishing process.

[0075] 4. The polishing belt 240 can simultaneously polish multiple locations on the alloy resistor strip material 20, which can effectively improve the polishing efficiency.

[0076] 5. During the translation process, the polishing belt 240 will keep in contact with the polished portion 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.

[0077] 6. During the polishing process, the entire surface of the polishing tape 240 participates in the polishing process of the alloy resistor strip material 20, thereby improving the utilization rate of the polishing tape 240 and extending the service life of the polishing tape 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.

[0078] In one embodiment, the outer wall of the limiting roller 300 is provided with thread-shaped limiting stripes (not shown), and the thread-shaped limiting stripes assist in winding the alloy resistance strip material 20 .

[0079] See also Figure 3 and Figure 4 In one embodiment, a winding motor 410 is mounted on the slide 400 to rotate the take-up reel 500. During polishing, the motor 410 rotates the take-up reel 500 in the forward direction, slowly unwinding the alloy resistance strip 20 and assisting in spirally winding the alloy resistance strip 20 around the limiting roller 300. After the polishing operation is completed, the motor 410 starts to rotate the take-up reel 500 in the reverse direction, while the slide 400 simultaneously drives the take-up reel 500 back along its original path. The two motors work together to wind the alloy resistance strip 20 around the limiting roller 300.

[0080] The present application also provides an alloy resistor production process, which is implemented by the above-mentioned automatic polishing device 10 for alloy resistor strips, and includes the following steps:

[0081] Step 1: Welding the conductors 22 on both sides of the resistor 21 to obtain the alloy resistor strip 20;

[0082] Step 2: Winding the alloy resistance strip material 20 into a bundle and transferring it to the winding reel 500;

[0083] Step 3: Pull out the alloy resistance strip 20 from the reel 500 and fix the end of the alloy resistance strip 20 on the limiting roller 300;

[0084] Step 4: While driving the winding disk 500 to translate along the axis of the limiting roller 300, the limiting roller 300 is kept rotating so that the alloy resistance strip is spirally wound on the limiting roller 300;

[0085] Step 5: Start the polishing motor 220 to allow the polishing belt 240 to polish the alloy resistance strip material on the limiting roller 300, and keep the limiting roller 300 rotating during the polishing process;

[0086] Step 6: Rotate the limiting roller 300 in the opposite direction to remove the polished alloy resistance strip material 20;

[0087] Step 7: The polished alloy resistor strip material 20 is granulated, resistance-adjusted, and electroplated to obtain the target alloy resistor.

[0088] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
