Abstract
Description
Technical Field
[0001] The present application relates to the technical field of welding strip processing, and in particular to a device for maintaining liquid level balance and a wire processing system. Background Art
[0002] The double-head tinning machine is a device used for soldering electronic components. It consists of a tin furnace, a tinning head, a tooling device and an air knife. The tinning head is used to apply tin liquid to the wire body. The two tinning heads of the tinning machine share a tin furnace. Each tinning head can operate independently, so that two lines can be soldered at the same time during the soldering process, greatly reducing the production cycle. The tooling equipment is used to fix and guide the wire body. The tooling equipment and the tinning head are set correspondingly and can be lifted or lowered separately when needed. The air knife is used to cool the wire body by blowing air.
[0003] In the actual production process, the two heads of the tinning machine work at the same time. When both tooling equipment are immersed in solder, the liquid level of the solder and the frequency of tinning are relatively stable. If one of the tinning heads is abnormal, such as the need to shut down for maintenance, the tooling equipment corresponding to the tinning head will be instantly lifted from the solder, causing the solder liquid level to drop instantly, below the standard liquid level. This instantaneous drop will affect the coating thickness of the line product in the other tooling equipment; then the automatic tinning system starts to replenish solder to the tin furnace to restore the liquid level to the standard liquid level. When the abnormality is handled and the tooling equipment is lowered into the solder again, the solder liquid level will rise instantly, higher than the standard liquid level. This instantaneous rise will also affect the coating thickness of the line product in the other tooling equipment.

[0029] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0030] As described in the background technology, in the actual production process, the two heads of the tinning machine work simultaneously. When both tooling equipment are immersed in solder, the liquid level height of the solder and the frequency of tinning are relatively stable. If one of the tinning heads is abnormal, such as the need to shut down for maintenance, the tooling equipment corresponding to the tinning head will be instantly lifted from the solder, causing the solder liquid level to drop instantly, below the standard liquid level. This instantaneous drop phenomenon will affect the coating thickness of the line product in the other tooling equipment; then the automatic tinning system is started to replenish solder to the tin furnace to restore the liquid level to the standard liquid level. When the abnormality handling is completed and the tooling equipment is lowered into the solder again, the solder liquid level will rise instantly, higher than the standard liquid level. This instantaneous rise phenomenon will also affect the coating thickness of the line product in the other tooling equipment.
[0031] Based on this, the present application provides a device for maintaining liquid level balance and a wire processing system, aiming to solve the technical problem of uneven wire coating thickness caused by liquid level fluctuations existing in the prior art.
[0032] Embodiment 1
[0033] refer to Figures 1 to 4 , a device for maintaining liquid level balance, applied to processing equipment, the processing equipment includes at least two processing heads, the device includes: a tooling device connected to the processing head, when immersed in the processing liquid, the processing liquid has a preset standard liquid level; a liquid level adjustment mechanism, including a regulating body, connected to the tooling device; wherein, when the tooling device moves out of the processing liquid, the regulating body is synchronously immersed in the processing liquid, and the volume of the regulating body is equal to the volume of the liquid displaced when the tooling device is immersed in the processing liquid, so that the liquid level of the processing liquid maintains the preset standard liquid level.
[0034] Among them, the device is suitable for a variety of usage scenarios, such as 3D printing, electroplating, chemical cleaning, tinning, etc. In the following embodiments, the tinning scenario is taken as an example for specific analysis, wherein the processing head is specifically a tinning head, the processing liquid is specifically tin liquid, and the wire body is specifically a solder strip.
[0035] In a specific embodiment, a fixed amount of processing liquid 10 is contained in the device, and the tooling equipment is used to penetrate and fix the line body, including a first tooling equipment 20 and a second tooling equipment 21, both of which are immersed in the processing liquid 10. At this time, Figure 1 The dotted line shown, the liquid level of the processing liquid 10 meets the preset standard liquid level. The regulating body includes a first regulating body 30 and a second regulating body 31, the first regulating body 30 is connected to the first tooling equipment 20, and the second regulating body 31 is connected to the second tooling equipment 21. The air knife is arranged above the processing liquid 10, and maintains a preset distance from the liquid surface with the preset standard liquid level.
[0036] In one case, if Figure 2 As shown, when the first tooling equipment 20 is lifted, the first tooling equipment 20 moves out of the processing liquid 10, and the liquid level decreases, the distance between the air knife and the liquid surface increases, which will cause the coating of the line body product in the second tooling equipment 21 to become thicker and the particles to be poor. If new liquid is added using the automatic liquid adding system later to make the liquid surface meet the preset standard liquid level, the first tooling equipment 20 is immersed in the processing liquid 10 again, and the liquid level rises, the distance between the air knife and the liquid surface decreases, which will cause the coating of the line body product in the second tooling equipment 21 to become thinner and the particles to be poor. In order to solve this problem and avoid using the secondary liquid adding method, when the first tooling equipment 20 moves out of the processing liquid 10, the first adjusting body 30 is simultaneously immersed in the processing liquid 10 to make the liquid level rise and the liquid level meet the preset standard liquid level.
[0037] In one case, if Figure 3 As shown, when the second fixture 21 is lifted, the second fixture 21 moves out of the processing liquid 10, and the liquid level decreases, the distance between the air knife and the liquid surface increases, which will cause the coating of the line body product in the first fixture 20 to become thicker and the particles to be poor. If new liquid is added using the automatic liquid adding system later to make the liquid surface meet the preset standard liquid level, the second fixture 21 is immersed in the processing liquid 10 again, and the liquid level rises, the distance between the air knife and the liquid surface decreases, which will cause the coating of the line body product in the first fixture 20 to become thinner and the particles to be poor. In order to solve this problem and avoid using the secondary liquid adding method, when the second fixture 21 moves out of the processing liquid 10, the second regulating body 31 is simultaneously immersed in the processing liquid 10 to make the liquid level rise and the liquid level meet the preset standard liquid level.
[0038] In one case, if Figure 4As shown, when the first fixture 20 and the second fixture 21 are lifted at the same time, the liquid level decreases. If new liquid is added using the automatic liquid adding system later to make the liquid level meet the preset standard liquid level, the first fixture 20 and the second fixture 21 are immersed in the processing liquid 10 again, and the liquid level rises, the distance between the air knife and the liquid level decreases, which will cause the coating of the line products in the first fixture 20 and the second fixture 21 to become thinner and have poor particles. To solve this problem and avoid using the secondary liquid adding method, when the first fixture 20 and the second fixture 21 are both removed from the processing liquid, the first adjustment body 30 and the second adjustment body 31 are simultaneously immersed in the processing liquid 10 to make the liquid level rise and meet the preset standard liquid level.
[0039] It should be noted that the volume of the first regulating body 30 is equal to the volume of the liquid displaced when the first tooling device 20 is immersed in the processing liquid 10, and the volume of the second regulating body 31 is equal to the volume of the liquid displaced when the second tooling device 21 is immersed in the processing liquid 10. The shape of the regulating body can be any shape, and the material is an alloy body such as stainless steel or titanium alloy.
[0040] In summary, the volume of the regulating body is equal to the volume of the liquid displaced by the tooling equipment, and the Archimedes principle can be directly used to achieve liquid level compensation when the tooling equipment is immersed in or removed from the processing liquid, solving the technical problem of uneven coating thickness of the wire body caused by liquid level fluctuations in the prior art. In addition, the device does not need to use a complex electronic control logic system for liquid level adjustment, and a linkage mechanical structure can ensure the balance of the liquid level, which is simple, low-cost, and highly reliable.

One end of the second connecting member 51 is connected to the second tooling equipment 21, and the other end is connected to the second adjusting body 31 after passing through the second sliding member 41.

Figures 1 to 4 As shown, the first sliding member 40 and the second sliding member 41 both use fixed pulleys. When the first tooling equipment 20 rises or falls, the first adjusting body 30 falls or rises synchronously, and the first sliding member 40 rotates. When the second tooling equipment 21 rises or falls, the second adjusting body 31 falls or rises synchronously, and the second sliding member 41 rotates.

Among them, the above-mentioned connection methods are all detachable connections, so as to realize the rapid disassembly and assembly when any part of the connector, tooling equipment and adjustment body needs to be repaired and replaced.
[0047] In an optional embodiment, the liquid level adjustment mechanism also includes a connecting rod assembly (not shown in the figure), which is connected between the tooling equipment and the adjustment body, and is used to convert the lifting movement of the tooling equipment into the lifting movement of the adjustment body, driving the adjustment body to be synchronously immersed in the processing liquid when the tooling equipment moves out of the processing liquid, and driving the adjustment body to be moved out of the processing liquid when the tooling equipment is immersed in the processing liquid.
[0048] Among them, compared with the sliding assembly, the connecting rod assembly has no flexible parts, such as the aforementioned steel cable, and has higher transmission accuracy.
