Technical Field
[0001] This invention relates to the field of resistor production, and in particular to a device for stable feeding of Z-shaped resistors based on an air gap. Background Technology
[0002] Production Figure 1 When the resistor 20 is shown in the figure-eight shape, pins 23 need to be soldered onto the two legs 22 of the resistor body 21. In existing production lines, a vibrating plate and guide rail are usually used for feeding. When feeding, the resistor body 21 is inverted and the soldered surfaces of the two legs are facing upwards and conveyed forward along the guide rail.
[0003] However, due to the small mass and thinness of the resistor 21, and the fact that the material on the guide rail is squeezed together during the feeding of the vibratory feeder, relying on the material behind to push the material in front forward, the resistor 21, located in the middle of the material pile, bears both the thrust from behind and the resistance from the front. It is prone to tilting and misalignment under the pushing action from both sides, which can lead to blockages and material jamming. The operator needs to remove the lifted resistor 21 to restore feeding, and frequent equipment adjustments will affect the normal production of the Z-shaped resistor 20.
[0004] On the other hand, when using a vibratory feeder, the power driving the resistor 21 forward comes from the vibration generated by the vibratory feeder. Therefore, there is a sufficient gap between the side of the guide rail 31 and the side of the resistor 21. If the gap is too small, the resistor 21 has little room to move and is not prone to misalignment or displacement. However, the friction generated by the contact between the resistor 21 and the surface of the guide rail 31 when it moves forward will hinder the normal feeding of the resistor 21. Conversely, if the gap is too large, the resistor 21 has more room to move and is more likely to stack during the feeding process, causing jamming.
[0005] Therefore, how to make the feeding of resistor 21 more stable is a problem that needs to be solved. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for stable feeding of Z-shaped resistors based on air gap, so as to prevent the resistors from being blocked during the feeding process and achieve stable feeding.
[0007] The objective of this invention is achieved through the following technical solution: A device for stable feeding of Z-shaped resistance based on air gap includes: a vibrating plate, an anti-detachment bracket, and a track; The track includes a converging platform and two guide plates. The converging platform is disposed between the two guide plates. Each guide plate has a bearing surface for supporting the legs of the resistor, so that the resistor is suspended above the converging platform. The side of the guide plate does not contact the resistor and forms an air gap. The converging platform is used to spray air into the air gap. The anti-detachment bracket includes an L-shaped support rod and a baffle. The L-shaped support rod is disposed on the vibrating plate, and the baffle is connected to the L-shaped support rod so that the baffle is suspended above the combiner table. The baffle is used to prevent the resistor from detaching from the guide plate.
[0008] In one embodiment, the combiner includes a housing, a sealing plate, and an air connector. The sealing plate seals the opening of the housing. The housing has two inclined surfaces facing the guide plates located between the two guide plates, and each inclined surface has multiple air holes, each air hole being inclined in the forward direction of the resistor. The guide plates have a limiting portion and a recessed portion on their sides. The limiting portion is located on the side adjacent to the bearing surface and faces the resistor. The recessed portion is located near the inclined surface, and a pressure relief port is provided at the boundary between the limiting portion and the recessed portion. There is no direct contact between the recessed portion and the limiting portion and the resistor.
[0009] In one embodiment, the width of the air gap at the location of the recess is greater than the width of the air gap at the location of the limiting portion.
[0010] In one embodiment, the track further includes a double-threaded screw rotatably disposed on the edge of the housing. The double-threaded screw has two threads with opposite directions of rotation, which are threadedly connected to the guide plates. Rotating the double-threaded screw drives the two guide plates to move away from or towards each other.
[0011] In one embodiment, the junction box further includes a direct vibrator connected to the bottom of the sealing plate, the direct vibrator being used to assist the advance of the resistive element on the bearing surface.
[0012] In one embodiment, the gas connector intermittently supplies pressurized gas to the housing.
[0013] In one embodiment, the track further includes a guide line connected to the vibrating plate via a bracket, the guide line being used to guide the resistive element from the vibrating plate into the guide plate.
[0014] In one embodiment, the vibrating plate is provided with a feed cylinder and a recovery cylinder that are connected to each other. The guide line extends from the feed cylinder to the guide plate and is located above the recovery cylinder. The recovery cylinder is used to recover the fallen resistor.
[0015] In one embodiment, an adjustment plate is provided at the connection position between the L-shaped support rod and the baffle. The adjustment plate has an elongated waist-shaped hole, through which the position of the baffle is adjusted so that the baffle is closer to or further away from the junction box.
[0016] A method for feeding Z-shaped resistors, based on the aforementioned device for stable feeding of Z-shaped resistors using an air gap, includes the following steps: Step 1: Place the resistor into the oscillating plate, and let the oscillating plate provide power to drive the resistor to move towards the guide plate; Step 2: The two legs on the resistor contact the bearing surfaces on the two guide plates respectively, so that the resistor is inverted and suspended above the combiner block; Step 3: The combiner unit sprays air into the resistor, assisting the resistor to move along the guide plate; and the high-pressure gas impacts the surface of the resistor, restoring it to a movable state; Step 4: The limiting part and the recessed part cooperate to guide the high-pressure airflow into the air gap, forming an air cushion at the air gap position to guide the resistor to move towards the center of the two guide plates, so that the tilted resistor is corrected. Step 5: The rear resistors sequentially enter the guide plate and push the front resistors forward along the guide plate, driving the resistors from the guide plate into the next processing device, completing the loading action. The above-described device and method for stable loading of Z-shaped resistors based on air gaps has the following beneficial effects: 1. The guide plate supports the resistor only with its bearing surface, and the side of the guide plate maintains a gap with the resistor to form an air gap. This ensures that the resistor only contacts the bearing surface during the conveying process, effectively reducing the contact area and frictional resistance during feeding, and ensuring that the resistor can move forward smoothly under the drive of the vibrating plate.
[0017] 2. The confluence platform sprays high-pressure gas towards the air gap. When the resistor body shifts laterally, the airflow generates a corrective force within the air gap, pushing it back onto the normal conveying path. Simultaneously, the baffle suspended above provides vertical restraint for the resistor body, preventing it from bouncing off the guide plate under the influence of the airflow. This combined action achieves non-contact correction and effectively avoids material stacking and jamming issues, thereby reducing the frequency of manual intervention and downtime for adjustments. 3. After high-pressure gas is continuously injected into the air gap, a stable air cushion isolation layer is formed between the resistor and the side of the guide plate, physically separating the two and eliminating the conditions for the generation of contact friction from the root. It takes into account both guiding accuracy and feeding smoothness, which avoids the resistor frequently rubbing against the guide plate due to the gap being too small, and also prevents the resistor position from shifting due to the gap being too large.

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0023] 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 invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0024] Please see Figure 2 This invention provides a device for stable feeding of a U-shaped resistor based on an air gap, comprising: a vibrating plate 100, an anti-detachment bracket 200, and a track 300. The track 300 is connected to a lead soldering device and is used to guide the resistor body from the vibrating plate 100 toward the lead soldering device.
[0025] Please see Figure 3 and Figure 4 The track 300 includes a junction platform 310 and two guide plates 320, which are spaced apart. The junction platform 310 is located between the two guide plates 320. Each guide plate 320 has a bearing surface 321, which supports the legs 22 of the resistor 21, so that the resistor 21 is suspended above the junction platform 310 (e.g., ...). Figure 6 As shown), the side of the guide plate 320 is not in contact with the resistor 21 and forms an air gap 11. The confluence platform 310 is used to spray gas into the air gap 11. The high-pressure gas increases the pressure at the air gap 11 and forms an air cushion at the air gap 11. In this way, when the resistor 21 moves along the guide plate 320, it is not easy to contact the side of the guide plate 320 under the action of the air cushion. The gap reserved between the guide plate 320 and the resistor 21 (i.e., the air gap 11) can be further reduced, which can prevent the resistor 21 from tilting or shifting during the feeding process and reduce the occurrence of jamming.
[0026] Please see Figure 3The anti-detachment bracket 200 includes an L-shaped support rod 210 and a baffle 220. The L-shaped support rod 210 is mounted on the vibrating plate 100, and the baffle 220 is connected to the L-shaped support rod 210 so that the baffle 220 is suspended above the combiner table 310. Since the combiner table 310 is located below the resistor 21 and sprays air upwards, the baffle 220 can form a blockage above the resistor 21. Whenever the resistor 21 has a tendency to bounce upwards, it will be blocked by the baffle 220, which can prevent the resistor 21 from falling off the guide plate 320.
[0027] It should be noted that the feeding device of this application is used for feeding lead soldering equipment. When soldering leads, the resistor 21 needs to be inverted so that the two legs 22 on the resistor 21 face upwards, so that the soldering equipment can solder the leads 23 at the ends of the legs 22. Since the vibrating plate relies on vibration to drive the material movement, high-frequency vibration needs to minimize the distance between the guide plate 320 and the outer surface of the resistor 21 to provide effective limit for the resistor 21. However, if the distance between the two is too small, the resistor 21 will frequently hit the side of the guide plate 320 due to vibration when moving, resulting in high resistance during the forward movement. If the distance between the two is too large, the movable space of the resistor 21 increases, and the probability of misalignment due to vibration during the feeding process increases. In actual production, processing errors are objectively present, and the dimensions of the resistor 21 vary. Simply increasing or decreasing the distance between the two guide plates 320 is insufficient to solve the problems of material jamming and obstruction during the feeding process. A larger resistor 21 is more likely to rub against the guide plate 320, while a smaller resistor 21 is more prone to misalignment due to vibration. The problem that needs to be solved is how to enable the guide plate 320 to overcome the dimensional errors of the resistor 21 caused by processing, and to prevent the resistor 21 from getting stuck on the guide plate 320 during the feeding process.
[0028] Please see Figure 4 and Figure 5 To solve the above problems, the manifold 310 includes a housing 311, a sealing plate 312, and an air connector 313. The sealing plate 312 seals the opening of the housing 311. The housing 311 has two inclined surfaces 31 facing the guide plates 320, located between the two guide plates 320. Each inclined surface 31 has multiple air holes 32, each inclined in the direction of the resistor 21's movement. The gas ejected from the air hole 32 both lifts the resistor 21 and generates a thrust in the direction of the resistor 21's movement. This allows the rear resistor 21 to more easily push the front resistor 21 forward, while simultaneously blowing the resistor 21 in the forward direction to disperse any stuck resistors 21, thus preventing jamming and blockage. Specifically, the air connector 313 connects to an external air source (such as an air pump) to supply high-pressure gas to the housing 311. High-pressure gas is ejected from the vent 32. Since the vent 32 is tilted in the direction of the resistor 21, the gas generates a thrust when it impacts the resistor 21, which helps it move forward along the guide plate 320.
[0029] Please see Figure 6 and Figure 7 The guide plate 320 has a limiting part 322 and a recessed part 323 on its side. The limiting part 322 is located on the side adjacent to the bearing surface 321 and faces the resistor 21. The recessed part 323 is located near the inclined surface 31, that is, the air hole 32 faces the location of the recessed part 323. A pressure relief port 33 is opened at the boundary between the limiting part 322 and the recessed part 323. There is no direct contact between the recessed part 323 and the limiting part 322 and the resistor 21.
[0030] Please see Figure 7 and Figure 8 The air gap 11 refers to the space between the guide plate 320 and the resistor 21. A limiting part 322 and a recessed part 323 are provided on the side of the guide plate 320, making the width of the air gap 11 wider at the bottom and narrower at the top. When high-pressure gas is ejected from the air hole 32, it can quickly enter the air gap 11 and then be discharged from the pressure relief port 33 at the boundary between the limiting part 322 and the recessed part 323. The gas flow direction is as follows... Figure 8 As shown by the middle arrow, when gas is injected into the air gap 11, the pressure at that location will increase. This is equivalent to forming an air cushion in the space between the resistor 21 and the side of the guide plate 320, making it less likely for the resistor 21 to scrape against the side of the guide plate 320 during the feeding process, which helps to reduce the resistance 21 generated during the feeding process.
[0031] This application also provides a method for feeding a U-shaped resistor, based on the above-mentioned device for stable feeding of U-shaped resistors using an air gap, comprising the following steps: Step 1: Place the resistor 21 into the oscillating plate 100, and the oscillating plate 100 provides power to drive the resistor 21 to move toward the guide plate 320; When the vibrating plate 100 is started, it generates vibration, which moves the resistor 21 toward the guide plate 320 by shaking it. During the feeding process, the resistor 21 located at the rear pushes the resistor 21 located at the front to move. Therefore, the resistors 21 entering the guide plate 320 are one after another.
[0032] Step 2: The two legs 22 on the resistor 21 contact the bearing surfaces 321 on the two guide plates 320 respectively, so that the resistor 21 is inverted and suspended above the combiner 310; The bearing surface 321 on the guide plate 320 is the part that supports the resistor 21. The two legs 22 on the resistor 21 are supported by the bearing surfaces 321 on the two guide plates 320 respectively. The resistor 21 is in an inverted state, and the resistor 21 is located above the combiner 310 throughout its movement on the guide plate 320.
[0033] Step 3: The combiner 310 sprays gas into the resistor 21, which helps the resistor 21 move forward along the guide plate 320; and the high-pressure gas impacts the surface of the resistor 21, making it movable again. The confluence platform 310 sprays air upwards. Since the air hole 32 is tilted towards the direction of the resistor 21, the air impacts the resistor 21 and generates an upward lifting force, as well as a thrust that drives the resistor 21 to feed. This makes it easier for the resistor 21 behind to push the resistor 21 in front forward. At the same time, the tilted airflow can blow away any stuck resistors 21 in the direction of the resistor 21's feed, preventing them from clogging the guide plate 320.
[0034] Step 4: The limiting part 322 and the recessed part 323 cooperate to guide the high-pressure airflow into the air gap 11, forming an air cushion at the position of the air gap 11 to guide the resistor 21 to move toward the center of the two guide plates 320, so that the tilted resistor 21 is corrected. The air hole 32 is located on the inclined surface 31, which faces the guide plate 320. That is, the high-pressure gas is directly injected into the guide plate 320 instead of the resistor 21. This prevents the direct injection from disrupting the normal feeding of the resistor 21 and allows the high-pressure gas to be quickly injected into the air gap 11, forming an air cushion between the resistor 21 and the guide plate 320. This makes it less likely for the resistor 21 to scrape against the side of the guide plate 320 during its forward movement.
[0035] Step 5: The rear resistor 21 enters the guide plate 320 in sequence and pushes the front resistor 21 forward along the guide plate 320, driving the resistor 21 from the guide plate 320 into the next processing equipment, completing the loading action.
[0036] It should be emphasized that the vent 32 is located on the inclined surface 31, so that the vent 32 is inclined towards the guide plate 320, allowing high-pressure gas to be quickly injected into the air gap 11, forming an air cushion at the air gap 11. Figure 7 As shown, there are air gaps 11 on both sides of the resistor 21. The air cushions generated at the air gaps 11 on both sides can keep the resistor 21 in the area of the center of the two guide plates 320 during the feeding process, preventing it from scraping against the limiting part 322 (the side of the guide plate 320) during the feeding process. At the same time, the air hole 32 itself is inclined towards the feeding direction of the resistor 21. When the high-pressure gas is sprayed upward, it is also inclined towards the feeding direction of the resistor 21. While the gas generates a supporting force, it can also push the resistor 21 forward along the guide plate 320. The baffle 220 faces the resistor 21, which can prevent the resistor 21 from jumping upward and prevent the resistor 21 from being blown away from the surface of the guide plate 320 when the air pressure is too high.
[0037] The above-mentioned device and method for achieving stable feeding of Z-shaped resistors based on air gaps have the following beneficial effects: 1. The support leg 22 of the resistor 21 on the guide plate 320 is supported only by the bearing surface 321. The side of the guide plate 320 maintains a gap with the resistor 21 and forms an air gap 11, so that the resistor 21 only contacts the bearing surface 321 during the conveying process, which effectively reduces the contact area and frictional resistance during feeding and ensures that the resistor 21 can move forward smoothly under the drive of the vibrating plate 100.
[0038] 2. The confluence platform 310 sprays high-pressure gas toward the air gap 11. When the resistor 21 shifts laterally, the airflow generates a corrective force in the air gap 11, pushing it back onto the normal conveying path. Simultaneously, the baffle 220 suspended above provides a vertical limit for the resistor 21, preventing it from bouncing off the guide plate 320 under the action of the airflow. The combined effect of these two mechanisms achieves non-contact correction and effectively avoids material stacking and jamming problems, thereby reducing the frequency of manual intervention and downtime for debugging. 3. After high-pressure gas is continuously injected into the air gap 11, a stable air cushion isolation layer is formed between the resistor 21 and the guide plate 320, physically separating the two and eliminating the conditions for the generation of contact friction from the root. It takes into account both guiding accuracy and feeding smoothness, which avoids the resistor 21 frequently rubbing against the guide plate 320 due to the gap being too small, and also prevents the resistor 21 from shifting position due to the gap being too large.
[0039] Please see Figure 7 In one embodiment, the width of the air gap 11 at the location of the recess 323 is greater than the width of the air gap 11 at the location of the limiting part 322. This makes the air gap 11 wider at the bottom and narrower at the top, and the pressure relief port 33 is located at the boundary between the limiting part 322 and the recess 323, allowing high-pressure gas to be quickly discharged at the narrowing position of the air gap 11, making the air pressure in the air gap 11 relatively stable, and preventing the air pressure in the air gap 11 from being too high, which would prevent the resistor 21 from feeding normally.
[0040] Please see Figure 4 and Figure 6 In one embodiment, the track 300 further includes a double-threaded screw 330, which is rotatably disposed on the edge of the housing 311. The double-threaded screw 330 has two threads 331 with opposite directions of rotation, which are threadedly connected to the guide plates 320. Rotating the double-threaded screw 330 drives the two guide plates 320 to move away from or towards each other. When producing Z-shaped resistors 20 of different specifications, the double-threaded screw 330 can be rotated to adjust the spacing between the two guide plates 320 according to the size of the resistor 21, so that the feeding device can adapt to the feeding requirements of resistors 21 of various sizes.
[0041] Please see Figure 2 and Figure 3In one embodiment, the junction box 310 further includes a direct vibrator 314, which is connected to the bottom of the sealing plate 312. The direct vibrator 314 is used to assist the resistor 21 on the bearing surface 321 in moving forward. It should be noted that when the resistor 21 moves onto the guide plate 320, it has detached from the vibrating plate 100. The vibration generated by the operation of the vibrating plate 100 can no longer serve as the driving force for the resistor 21 to move forward at this position. It mainly relies on the resistor located behind the vibrating plate 100 to push it forward. The guide plate 320 is connected to the junction box 310. By setting the direct vibrator 314 on the junction box 310, the vibration of the direct vibrator 314 can drive the resistor 21 on the guide plate 320 to move forward, which serves as an auxiliary means to make the feeding process of the resistor 21 smoother.
[0042] In one embodiment, a sealing strip is attached to the sealing plate 312 at the position where it contacts the outer casing 311. This improves the sealing performance of the manifold 310 and prevents air leakage that could lead to uncontrollable air pressure within the air gap 11.
[0043] Please see Figure 2 In one embodiment, the track 300 further includes a guide line 340, which is connected to the vibrating plate 100 via a bracket 341. The guide line 340 guides the resistor 21 from the vibrating plate 100 into the guide plate 320. The guide line 340 connects the vibrating plate 100 and the guide plate 320, ensuring stable feeding of the resistor 21. The vibrating plate 100 is provided with a feed cylinder 110 and a recovery cylinder 120 that are connected. The guide line 340 extends from the feed cylinder 110 to the guide plate 320 and is located above the recovery cylinder 120, which is used to recover any fallen resistors 21. When the guide line 340 falls, the resistor 21 will fall into the recovery cylinder 120 and then re-enter the feed cylinder 110 from the recovery cylinder 120 to resume feeding, preventing the fallen resistors 21 from scattering around the equipment.
[0044] Please see Figure 3 and Figure 4 In one embodiment, an adjusting plate 230 is provided at the connection position between the L-shaped support rod 210 and the baffle 220. The adjusting plate 230 has an oblong hole 231. The position of the baffle 220 is adjusted through the oblong hole 231 so that the baffle 220 is closer to or further away from the combiner table 310. This makes the position of the baffle 220 adjustable. The position of the baffle 220 is adjusted according to the size of the resistor 21 so that the baffle 220 can always limit the upward floating distance of the resistor 21 and prevent it from being blown out of the guide plate 320 by high-pressure gas.
[0045] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.

10. A method for feeding a Z-shaped resistor, based on the apparatus for stable feeding of a Z-shaped resistor using an air gap as described in any one of claims 2 to 9, characterized in that, Includes the following steps: Step 1: Place the resistor into the oscillating plate, and let the oscillating plate provide power to drive the resistor to move towards the guide plate; Step 2: The two legs on the resistor contact the bearing surfaces on the two guide plates respectively, so that the resistor is inverted and suspended above the combiner block; Step 3: The combiner unit sprays air into the resistor, assisting the resistor to move along the guide plate; and the high-pressure gas impacts the surface of the resistor, restoring it to a movable state; Step 4: The limiting part and the recessed part cooperate to guide the high-pressure airflow into the air gap, forming an air cushion at the air gap position to guide the resistor to move towards the center of the two guide plates, so that the tilted resistor is corrected. Step 5: The rear resistors sequentially enter the guide plate and push the front resistors forward along the guide plate, driving the resistors from the guide plate into the next processing equipment, thus completing the loading action.
