Description

Technical Field

[0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to a soldering cleaning system for a network transformer. Background Art

[0002] A network transformer, also known as a network isolation transformer or pulse transformer, is an electronic component used for data transmission and signal isolation. It is widely used in network communications, industrial control, power systems and other fields. A network transformer includes core materials, coil structures, insulation materials, pins and welding, shielding and packaging. The core usually uses a ferrite core. The coil can be wound in a single layer or multiple layers. The insulation material is used to ensure electrical isolation between the coils. The pins are made of copper or other conductive materials and are connected to the coil by welding. In order to reduce electromagnetic interference, some network transformers are designed with metal shielding. The outer shell can be plastic or metal to protect the internal structure and provide mechanical support.

[0003] The manufacturing process of network transformers includes core preparation, coil winding, pin welding, insulation treatment, shielding and packaging, as well as testing and aging treatment. According to the design requirements, the primary and secondary coils need to be wound on the core during production. Winding is usually done manually, and there are a small number of automated equipment dedicated to winding network transformers. The wound coils are welded to the pins to ensure the reliability of the connection and electrical performance.

[0004] However, due to its small size and large number of pins, the efficiency is low if each pin is welded separately. In the prior art, the dip soldering process is usually used for the welding of coils and pins, that is, several network transformer winding semi-finished products are placed in corresponding containers through jigs for dip soldering. After welding, the network transformer needs to be cleaned. The existing cleaning methods include semi-automatic and automatic, but the cleaning equipment is usually modified from the existing PCB board cleaning equipment to be suitable for the cleaning of network transformers. Different from the cleaning process of PCB boards, network transformers are usually loaded with jigs with larger areas due to their small size and large number of pins, resulting in more pins and points to be cleaned on each jig, and their uniform distribution density is large, resulting in poor cleaning effect. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a solder cleaning system for a network transformer, which aims to address the problem that PCB cleaning equipment used in the prior art cannot be well applied to the cleaning process of the network transformer.

[0026] Embodiment 1: This embodiment discloses a solder cleaning system for a network transformer, which is used to clean a semi-finished network transformer after the pin winding is dip-soldered. The network transformer in this embodiment is set on a jig 2 for transfer and cleaning, and a plurality of network transformers are placed on the jig 2 at equal intervals. Specifically, the jig 2 in this embodiment is a flat plate structure, and a plurality of mounting grooves or mounting holes that are suitable for the shell of the network transformer are set on its surface, and the network transformer is placed in the mounting groove or mounting hole to form a limit.

[0027] Specifically, the cleaning system includes two independent cleaning units, namely, an ultrasonic cleaning unit 11 and a flip cleaning unit 10. The cleaning system also includes a material grabbing mechanism, which can transfer the fixture 2 between the cleaning units.

[0028] Among them, the ultrasonic cleaning part 11 and the flip cleaning part 10 are determined according to the number of network transformers to be cleaned at a single time, generally including at least two ultrasonic cleaning parts 11 corresponding to one flip cleaning part 10, and the grabbing mechanism can correspond to one group of cleaning units, or can correspond to several groups of cleaning units. The grabbing mechanism transfers the jig 2 carrying a certain number of network transformers on the outside from the production mechanism of the previous step to the ultrasonic cleaning part 11, and then enters the flip cleaning part 10 after cleaning by the ultrasonic cleaning part 11, and finally the grabbing mechanism transfers the jig 2 out of the flip cleaning part 10.

[0029] The ultrasonic cleaning part 11 has an independent shell, which is an open container structure, and is set on the ground or other fixed structures with the opening facing upward, and is provided with corresponding supporting pipeline equipment. The ultrasonic cleaning part 11 has a placement position in which at least one fixture 2 can be placed, and the cleaning liquid filled in the ultrasonic cleaning part 11 can completely submerge the fixture 2 when the fixture 2 is placed on the placement position, and then the ultrasonic generator is set to continuously perform static cleaning. After the set cleaning time is completed, the gripping mechanism connects the fixture 2 from below the water surface and lifts it out.

[0030] It should be noted that the cleaning liquid used in the ultrasonic cleaning part 11 in this embodiment is usually deionized water. In some embodiments, pure water that meets laboratory requirements is used, or a special cleaning detergent is used. However, in this ultrasonic cleaning process, clean water is mainly used. In specific implementation, additional cleaning agents will be added to assist cleaning according to demand and cleaning volume. This embodiment does not limit the configuration of the cleaning liquid.

[0031] The flip cleaning part 10 is different from the ultrasonic cleaning part 11. It is not filled with cleaning liquid. When the fixture 2 enters, the inside is empty. The flip cleaning part 10 meets at least two functional requirements, that is, a water spraying structure is provided inside, and the fixture 2 entering the flip cleaning part 10 is sprayed with water in multiple directions for cleaning. After the spraying process is completed, high-pressure gas is introduced for drying, and the fixture 2 is taken out and transferred after drying.

[0032] The flip cleaning section 10 has movable components therein, so that the entering fixture 2 can move relative to the spraying water flow and air flow, thereby achieving better cleaning and drying effects.

[0033] It should also be noted that the entire system also has a control module and other supporting facilities, which are designed to control all electronic control components through the control module, and sensors are provided on the corresponding functional components to obtain various information of the current system, and adjust the water volume and air volume according to the feedback from the sensors.

[0034] Further, refer to Figure 1-Figure 12, and provide a detailed explanation of the implementation plan.

[0035] First, the whole system is an integrated device with a frame 1 structure based on a metal frame. The frame 1 structure is divided into three layers: upper, middle and lower according to the installed equipment.

[0036] Reference Figure 2 It can be seen that a truss 4 is provided on the upper layer of the frame 1, and the truss 4 can be used as a track. The material grabbing mechanism is provided on the truss 4 and reciprocates along the truss 4. There are many ways of controlled movement. Since the material grabbing mechanism is used to transfer the jig 2 carrying a number of network transformers, its weight is not large, and there is no excessive load requirement for its mobile structure to move controlled along the truss 4. The material grabbing mechanism can be driven to move by a reciprocating belt or rack in the truss 4, and a wheel or gear mechanism with a motor can also be provided to drive the entire material grabbing mechanism to move.

[0037] Reference Figure 1 The lower layer of the frame 1 is provided with an ultrasonic cleaning part 11 and a flip cleaning part 10 arranged side by side. In this embodiment, two ultrasonic cleaning parts 11 and one flip cleaning part 10 are provided.

[0038] Reference Figure 5 and Figure 6 A water circulation module is also provided in the lower layer of the frame 1 corresponding to the two ultrasonic cleaning parts 11 and the flip cleaning part 10. The water circulation module includes a pipeline group, a circulating water tank 13, a circulating pump and a filter. The circulating water tank 13 is respectively connected to the two ultrasonic cleaning parts 11 and the flip cleaning part 10 through the pipeline group. The circulating pump is not limited to the position and number of the setting. Generally, the circulating pump is set on the pipeline group to send the water in the circulating water tank 13 into the corresponding ultrasonic cleaning part 11 and the flip cleaning part 10. At the same time, multiple circulating pumps can be set to form a negative pressure at the water inlet of the circulating water tank 13, so as to facilitate the waste water in the ultrasonic cleaning part 11 and the flip cleaning part 10 to be sucked into the circulating water tank 13.

[0039] Reference Figure 6 There is a through channel in the middle layer of the frame 1, and the openings of the two ultrasonic cleaning parts 11 and the flip cleaning part 10 are both located in the channel. The fixture 2 grasped by the grasping mechanism will be transferred in the channel. The grasping mechanism has a grasping part, which can move horizontally and vertically in the channel.

[0040] exist Figure 2On the right side, the upper frame 1 has an extension to the right, which exceeds the middle frame 1 and extends outward by a certain distance, and the extension distance is at least greater than the width of the jig 2, and a tripod with oblique support is provided on the middle frame 1. At the same time, the truss 4 arranged in the upper layer also extends outward along with the extension, and the mobile frame arranged on the truss 4 can slide from the connection between the upper layer and the middle layer to the extension, so that the jig 2 clamped by the mobile frame can be moved out of the middle frame 1 and placed on the external docking structure at the extension. In some embodiments, the docking structure is a conveyor belt, and the mobile frame can place the jig 2 on the conveyor belt and the conveyor belt will transport it to the next processing mechanism for disposal.

[0041] An observation window 9 that can be flipped open is provided at the channel on the front side of the frame 1. The entire system generally operates automatically, and the operator does not need to operate frequently. The purpose is to conduct regular inspections according to operating specifications. The operating status of the equipment can be checked by opening the observation window 9 during the inspection.

[0042] The shells of the flip cleaning part 10 and the ultrasonic cleaning part 11 are similar in size, so that they have openings of the same size, and corresponding automatic covers 5 are provided at the openings of the flip cleaning part 10 and the ultrasonic cleaning part 11. The automatic cover 5 includes a sliding cover that slidably cooperates with the opening of the flip cleaning part 10 or the ultrasonic cleaning part 11, and then also includes a hydraulic rod / pneumatic rod that is transmission-connected to the sliding cover, and the flip cleaning part 10 and the ultrasonic cleaning part 11 are controlled to open / close the cover through the control module. During cleaning, the automatic cover 5 will be covered to form a closed space, and after cleaning is completed, the automatic cover 5 will be controlled to open to facilitate the transfer of materials.

[0043] Reference Figure 8 , Figure 10-12 The ultrasonic cleaning part 11 includes a rectangular shell structure, which is fixed to the water tank frame 17 in the frame 1. The shell is provided with a heating pipe 20, an ultrasonic module 21, a shelf 22, a liquid level meter 23 and a water inlet and outlet module. The water inlet and outlet module and the ultrasonic module 21 in this embodiment are integrated into one body. Fig.11 The ultrasonic module 21 is a square box structure, one side of which has a water inlet 18 and a water outlet pipe 19, and is connected to an external pipeline group through the water inlet 18 and the water outlet pipe 19.

[0044] The ultrasonic cleaning part 11 needs to maintain a certain level of cleaning liquid, and the liquid level sensor 23 is a floating structure that can change in the liquid as the liquid level changes. The liquid level sensor 23 obtains the height change of the liquid level in the ultrasonic cleaning part 11 in real time, and the control module controls the water intake of the circulating water pump through the liquid level sensor 23.

[0045] The heating tube 20 is arranged on both sides of the ultrasonic module 21 and is designed as a U-shaped structure, which can heat the internal cleaning liquid to ensure that it has a certain solubility during the cleaning process.

[0046] The rack 22 is arranged on the upper part of the ultrasonic module 21, and has a table top for conveniently placing a flat-plate-style fixture 2. There is a large gap between the entire rack 22 and the opening of the shell, so as to facilitate the setting of multiple layers of stacked fixtures 2. The ultrasonic cleaning part 11 can clean several fixtures 2 at a time, thereby improving its cleaning efficiency.

[0047] Further, refer to Figure 5 , it can be seen that the flip cleaning part 10 is arranged at the rear end of the channel, and the housing structure has the same size and shape as the ultrasonic cleaning part 11. A blower 12 is also arranged at the lower side of the flip cleaning part 10, and a high-pressure airflow is formed inside the flip cleaning part 10 by the blower 12.

[0048] Among them, the flip cleaning part 10 is provided with a spray pipe and an air blowing pipe, and also includes a blower 12 controlled by a control module and connected to the air blowing pipe; the spray pipe and the air blowing pipe have at least two groups and are symmetrically arranged in the flip cleaning part 10, a flip frame is arranged between the two groups of spray pipes and air blowing pipes, and the fixture 2 is arranged on the flip frame.

[0049] The shell of the flip cleaning part 10 is fixed on the frame 1, and the internal flip frame is rotatably connected to the shell, and the flip frame is driven by an external rotating motor to rotate circumferentially in the shell. At the same time, the air blow pipe on the shell is also rotatably connected to the shell, and the air blow pipe is driven by a hydraulic push rod assembly arranged on the side of the shell to rotate within a certain range, that is, a 60° fan-shaped flip angle toward the flip frame. The hydraulic push rod assembly can make it sweep 60° up and down toward the flip frame within this angle range.

[0050] Reference Figure 7 and Fig. 9 The material grabbing mechanism includes a movable frame and a grab hook 14. The grab hook 14 has a hook portion that hooks and lifts the jigs 2 from the bottom of a plurality of stacked jigs 2, and the jigs 2 entering the ultrasonic cleaning part 11 and the flip cleaning part 10 remain in a stacked state.

[0051] The mobile frame includes a vertical slide 16, and the lead screw structure provided inside the vertical slide 16 provides vertical limit sliding control for the slider slidably provided on the upper part thereof. The upper side of the vertical slide 16 has a sliding mechanism, and the vertical slide 16 is moved along the truss 4 as a whole through the cooperation of the sliding mechanism and the truss 4.

[0052] The slider on the vertical slide 16 is connected to a door-shaped material grabbing vertical frame 8, and the lower end of the material grabbing vertical frame 8 is connected to a material grabbing horizontal frame 3. The grab hook 14 is arranged on the material grabbing horizontal frame 3 and can perform clamping and releasing operations at the lower part of the material grabbing horizontal frame 3.

[0053] Further, see Fig. 9 The material grabbing frame 8 mainly includes two vertically arranged profile strips, the upper ends of the two profile strips are connected to each other through a slider, and the slider can reciprocate on the vertical slider 16. A horizontally arranged shorter profile strip is provided at the lower part of the two profile strips for fixing. The lower ends of the two profile strips are connected to a horizontally arranged profile frame, and the profile frame is provided with a slide rail. The two material grabbing frames symmetrically arranged on the profile frame slide with the slide rail, and the horizontal push cylinder 15 arranged between the two profile strips provides the power for lateral displacement.

[0054] Reference Fig. 9 The horizontal push cylinder 15 is directly fixed on the material grabbing frame 8 or the profile frame, and various transmission methods can be used. The purpose is to control the relative displacement of the two symmetrically arranged material grabbing frames. One side of the material grabbing frame can be fixed to control the movement of the other side of the material grabbing frame. The solution shown in the figure is to set a symmetrical horizontal push cylinder 15, that is, it has two left and right push rods, which are connected to the material grabbing frames on both sides at the same time to control their relative clamping or separation.

[0055] Reference Figure 7 Each material grabbing cross frame is provided with a group of grab hooks 14, i.e. a strip-shaped structure, one end of which is fixed on the material grabbing cross frame, and one end of which extends downward for a certain length and forms a latch at the extended end. The grab hooks 14 on the same material grabbing cross frame are arranged at the two ends of the length direction of the material grabbing cross frame, and the latches face the same direction.

[0056] The fixture 2 in this embodiment is a frame 1 structure, which has an annular frame on the outside and a hollow plate for placing a number of network transformers on the inside. The annular frame is provided with a socket for engaging with the bayonet. The socket is a conical hole structure, which is small inside and large outside, and is convenient for guiding the bayonet to be inserted from the outside. The upper and lower surfaces of the annular frame of the fixture 2 are respectively provided with a clamping limit structure, which facilitates the overlapping placement of a number of fixtures 2 and forms a certain limit effect.

[0057] Reference Figure 7In this embodiment, the single cleaning object entering the cleaning system is two overlapping fixtures 2. When the material grabbing cross frame is clamped, the grab hooks 14 on both sides correspond to the fixtures 2 on the lower layer. A downward identification camera is provided at the corresponding position of the material grabbing cross frame or the material grabbing vertical frame 8. The plane position of the fixture 2 can be identified by the identification camera. At the same time, there is an area for the fixture 2 to enter on the left side of the frame 1 of the system. The area is the feeding area 6, that is, a platform set on the left side of the middle layer of the frame 1. It has a placement plane. An operation panel 7 is provided on the upper part of the feeding area 6, and a PLC control module is provided inside. Other identification cameras are also provided in the feeding area 6 to determine the number of layers of the fixture 2 entering. When grabbing materials, the material grabbing cross frame is controlled by the system, and position identification and quantity identification are performed in the area where the fixture 2 is placed. After determining the quantity, the grab hook 14 is controlled to move downward to the placement plane, and then the fixture 2 on the bottom layer is clamped and lifted up as a whole for movement.

[0058] It should be noted that, by setting a number of sensors and identification cameras on the frame 1, this embodiment can autonomously adapt and adjust according to the position and number of the entering jigs 2, that is, the moving distance of the grab hook 14, and the water level height and water spraying and blowing range of the ultrasonic cleaning part 11 and the flip cleaning part 10. However, when the grab hook 14 grabs, even if there is no identification camera in the horizontal direction, when the number of layers of the jig 2 cannot be determined, it can also be set through the program so that each time it grabs, it only needs to identify the plane position of the jig 2 from above, and lower the grab hook 14 to a position close to the placement plane, so that it can be clamped and fixed with the jig 2 on the bottom layer.

[0059] The present invention is not limited to the above optional implementations, and anyone can derive other various forms of products under the enlightenment of the present invention. The above specific implementations should not be understood as limiting the scope of protection of the present invention. The scope of protection of the present invention should be based on the definition in the claims, and the description can be used to interpret the claims.
