[0029] As disclosed in the background technology, the tinning operation for the lead-out terminals of capacitor products in the prior art is basically done manually. Manual operation has the following disadvantages:

[0030] 1. Manual operation has a large workload and low efficiency, which is not suitable for mass production.

[0031] 2. There are many discrete operations in manual tinning, which leads to differences in the tinning depth, tinning area and tin layer quality on the product lead-out terminals. In addition, the different tinning depths of the products or the different lengths of time the product lead-out terminals are in the high-temperature tin liquid lead to differences in the impact of the high temperature of the tin liquid on product performance.

[0032] 3. The waste gas and waste liquid generated during the process of flux dipping, tin dipping, flux cleaning, etc. are harmful to the human body.

[0033] 4. The high temperature during tinning and drying of products after cleaning can easily cause burns.

[0034] In order to solve the above problems, the present invention provides an automated tinning equipment, which has a good tinning effect, avoids a series of problems caused by manual operation, and improves the tinning efficiency. Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] First embodiment

[0036] Please refer to Figures 1 to 3This embodiment provides an automated tinning equipment 100, which uses an automated production line to automatically complete all operations such as flux dipping, tin dipping, cleaning, rinsing, drying, and unloading. It has a small workload, a high degree of automation, avoids manual operation, and has high production efficiency. At the same time, it is circulated in units of fixtures 181, and multiple products can be operated at a time, which further improves efficiency and is very suitable for mass production. At the same time, the equipment operates automatically with good consistency. Since the depth and time of the product leads / terminals in the high-temperature tin liquid are small, the high temperature of the tin liquid has little effect on product performance, which ultimately ensures the consistency of product tinning quality and product performance. Equipment automation also reduces the harm to the human body caused by waste gas, waste liquid, etc. generated during the processes of flux dipping, tin dipping, and flux cleaning, and the product is unloaded only after it has cooled, reducing the risk of burns to personnel caused by high temperatures during tin dipping and drying after product cleaning.

[0037] The present embodiment provides an automated tinning equipment 100, including a feeding vibration plate 110, a horizontal conveying track 120, a flux-containing immersion tank 130, a tinning tank 140, a cooling conveying track 150, and a cleaning and drying production line 160. The feeding vibration plate 110 is used to realize the feeding of multiple products. The horizontal conveying track 120 is arranged downstream of the feeding vibration plate 110 so that multiple products are arranged on the horizontal conveying track 120. The flux-containing immersion tank 130 and the tinning tank 140 are sequentially arranged downstream of the horizontal conveying track 120. The cooling conveying track 150 is arranged downstream of the horizontal conveying track 120. A first conveying track 170 for movably carrying a plurality of products is provided downstream of the tin immersion tank 140, and above the flux immersion tank 130 and the tin immersion tank 140, so that the plurality of products move along the first conveying track 170 and sequentially pass through the flux immersion tank 130 and the tin immersion tank 140, the flux immersion tank 130 is used to immerse flux on the lead-out end surface of the product, the tin immersion tank 140 is used to immerse tin on the lead-out end surface of the product, and the cleaning and drying production line 160 is provided downstream of the cooling conveying track 150, and is used to clean and dry the products.

[0038] The automated tin dipping equipment 100 provided in this embodiment is used to realize automated tin dipping operations on capacitor products. The capacitor products are loaded by a robot or manually. Of course, only capacitor products are used as an example here for illustration, but any electrical products that require tin dipping operations are within the protection scope of the present invention.

[0039] In this embodiment, the various components of the automated tinning equipment 100 are arranged in sequence, wherein the loading vibration plate 110, the horizontal conveying track 120, the flux-containing immersion tank 130, the tinning tank 140 and the cooling conveying track 150 constitute a tinning production line, which is arranged in a horizontal direction, and the cleaning and drying production line 160 can be arranged below the tinning production line to form an upper and lower distribution structure, that is, the upstream side of the cleaning and drying production line 160 is located below the cooling conveying track 150, and the downstream side of the cleaning and drying production line 160 is located below the loading vibration plate 110. Of course, in other preferred embodiments of the present invention, the cleaning and drying production line 160 can also continue to be arranged in the horizontal direction on the downstream side of the tinning production line to form a horizontal distribution structure, and the arrangement of the various components of the automated tinning equipment 100 is not specifically limited here.

[0040] It should be noted that the upstream and downstream in this embodiment refer to the upstream or downstream in the movement direction of the capacitor product, wherein the capacitor product passes through various production components in sequence, that is, passes through the tin dipping production line and the cleaning and drying production line 160 in sequence, and moves from upstream to downstream.

[0041] The automatic tinning equipment 100 provided in this embodiment enables the product to pass through the flux-containing immersion tank 130 and the tinning tank 140 in sequence through the first conveying track 170 to complete the automatic tinning action, and after the tinning is completed, the cleaning and drying actions are completed through the cleaning and drying production line 160. Due to the adoption of the automatic track solution, automatic tinning, cleaning and drying are realized, and only the loading and unloading actions need to be completed manually, avoiding manual operation during tinning, and the consistency between the various devices is good, ensuring the tinning effect, avoiding a series of problems caused by manual operation, and improving the tinning efficiency.

[0042] It should be noted that in this embodiment, both ends of the first conveying track 170 are connected to the horizontal conveying track 120 and the cooling conveying track 150, respectively, so that multiple products can be conveyed from the horizontal conveying track 120 to the first conveying track 170, and then conveyed from the first conveying track 170 to the cooling conveying track 150. The cooling conveying track 150 is relatively long, and the products that have been tinned can be manually inspected in this area to ensure the tinning effect.

[0043] In this embodiment, a cooling zone 151 is provided at one end of the cooling conveying track 150 close to the tin immersion tank 140, and a cooling fan is provided in the cooling zone 151. The cooling fan is used to cool the product after the tin immersion is completed. Specifically, the cooling fan can be provided separately through a support frame, or can be directly provided at the edge of the cooling conveying track 150. The cooling fan can cool the product through air cooling. Of course, in other preferred embodiments, the cooling of the product can also be achieved by water cooling or coolant, which is not specifically limited here.

[0044] In this embodiment, a first transfer robot 180 is further provided on one side of the horizontal conveying track 120. A clamp 181 is detachably provided on the first transfer robot 180. The clamp 181 is used to clamp a plurality of products on the horizontal conveying track 120 at the same time. The first transfer robot 180 is used to place the clamp 181 holding a plurality of products into the first conveying track 170. Specifically, the first transfer robot 180 carries a clamp 181 to clamp a certain number of products at a time. When clamping, the clamp 181 clamps the product body with the lead exposed downward. Then, the clamp 181 holding a certain number of products is placed into the first conveying track 170. The clamp 181 carrying the product passes through the flux immersion tank 130 and the tin immersion tank 140 in sequence on the first conveying track 170 and reaches the cooling zone 151, completing operations such as immersing the product in flux, immersing in tin, and fan cooling after immersing in tin.

[0045] It should be noted that in this embodiment, the clamp 181 is used to realize the simultaneous turnover of multiple products, which greatly improves the tinning efficiency of the products, and also ensures the consistency of the tinning action of the products, further ensuring the tinning effect. In addition, here only the clamp 181 is used as an example to illustrate the transfer process. In other preferred embodiments of the present invention, the transfer of multiple products can also be achieved by other methods, such as a combination of chains and clamps, a method of vacuum adsorption of products, etc. The transfer method and transfer tools of multiple products are not detailed here.

[0046] It should also be noted that the structural shape of the clamp 181 here is compatible with the structural shape of the capacitor product, so that the clamp 181 can realize the clamping action of multiple products. When the specifications and models of the capacitor products change, it is only necessary to change the form of the clamp 181 according to the structure of the different capacitor products or use other similar functional mechanisms to make the device suitable for all capacitor products.

[0047] In this embodiment, a first lifting mechanism 131 is provided below the flux impregnation tank 130, and the first lifting mechanism 131 is used to lift the flux impregnation tank 130 close to the first conveying track 170 so as to immerse the flux on the lead-out surface of the product; a second lifting mechanism 141 is provided below the tin immersion tank 140, and the second lifting mechanism 141 is used to lift the tin immersion tank 140 close to the first conveying track 170 so as to immerse the solder on the lead-out surface of the product. Specifically, both the flux impregnation tank 130 and the tin immersion tank 140 use up and down movements to immerse the lead-out end of the product in flux and tin. Here, the immersion depth can be controlled by a sensor, or a constant immersion depth can be achieved by fixing the position and lifting height of the first conveying track 170. Of course, the flux and tin are impregnated by moving the flux tank and the tin tank up and down as a whole. A small tank can also be set in the flux tank and the tin tank respectively. Each time the small tank is filled with flux liquid and tin to ensure the liquid level, and the flux and tin are impregnated by moving the small tank up and down. There are many ways to impregnate the flux and tin, which are not limited to the methods mentioned in this embodiment, and are not specifically limited here.

Preferably, the airflow interface 166 is arranged above the second conveying track 164 to blow out air, and the liquid droplets on the product and the fixture 181 on the second track are blown down by blowing air, and are taken away by the liquid receiving tray 167. Of course, the airflow interface 166 here can also be arranged below the second conveying track 164 to inhale air, so as to form a downward airflow on the surface of the product and the fixture 181 by negative pressure adsorption, so as to blow the liquid droplets on the product and the fixture 181 downward and be taken away by the liquid receiving tray 167.

[0051] In this embodiment, a third lifting mechanism 1611 is provided below the ultrasonic cleaning tank 161, and the third lifting mechanism 1611 is used to lift the ultrasonic cleaning tank 161 close to the second conveying track 164 to complete the ultrasonic cleaning of the product; a fourth lifting mechanism 1621 is provided below the ultrasonic rinsing tank 162, and the fourth lifting mechanism is used to lift the ultrasonic rinsing tank 162 close to the second conveying track 164 to complete the ultrasonic rinsing of the product.

The structure and working principle of the ultrasonic cleaning tank 161 and the ultrasonic rinsing tank 162 can refer to the relevant description in the prior art. In addition, sensors can also be used here to control the cleaning or rinsing depth, or the cleaning depth can be controlled by maintaining liquid overflow.

[0052] In this embodiment, a second transfer robot 190 is further provided between the ultrasonic cleaning tank 161 and the cooling conveying track 150, and the second transfer robot 190 is used to place the fixture 181 holding a plurality of products into the second conveying track 164. Specifically, the first conveying track 170 and the second conveying track 164, the cooling conveying track 150 and the second conveying track 164 are parallel to each other and arranged up and down, and the second transfer robot 190 is arranged between the cooling conveying track 150 and the second conveying track 164. The second transfer robot 190 can remove the cooled products and the fixture 181 from the cooling conveying track 150 and place them into the second conveying track 164.

[0053] In this embodiment, a material receiving device 168 is further provided downstream of the drying device 163, and the material receiving device 168 is used to receive a plurality of products taken out from the clamp 181.

[0054] It should be noted that the robot at the unloading point here can also be replaced by the first transfer robot 180, so that the robot at the loading point and the robot at the unloading point can be shared. The first transfer robot 180 takes out the dried clamp 181 with multiple products, and opens the clamp 181 to realize the unloading of multiple products. After unloading, the clamp 181 follows the first transfer robot 180 back to the horizontal conveying track 120 to re-grip multiple products, forming a new cycle.

[0056] Lead-type capacitor products are loaded through the loading vibration plate 110, neatly arranged on the horizontal conveying track 120, and the body is ensured to face upward and the positive and negative leads are facing downward. Then the first transfer robot 180 carries a clamp 181 to clamp a certain number of products at one time, wherein the clamp 181 clamps the product body with the product's leads exposed downward, and then the clamp 181 with the product is placed in the first conveying track 170.

[0057] The fixture 181 carrying the product passes through the flux-containing immersion tank 130 and the tin-immersion tank 140 on the first conveying track 170 in sequence, and arrives at the cooling zone 151 to complete the operations of immersing the product in flux, tinning and cooling. During the immersion in flux and tinning, the flux-containing immersion tank 130 and the tin-immersion tank 140 move up and down to achieve the goal of immersing the product leads in flux and tinning. The immersion depth is mainly controlled by a sensor. At the same time, a cooling fan is set in the cooling zone 151 after tinning for cooling. After cooling, it is transported by the cooling conveying track 150. In this area, the products after tinning can be manually inspected to ensure the tinning effect.
