Description

Technical Field

[0001] The invention relates to the technical field of electronic component welding, and in particular to a clamping feeding electronic component welding device and method. Background Art

[0002] Electronic components are the basic elements that make up electronic products and are the smallest units of electronic devices. They are usually made of semiconductor materials, metal materials or other materials, including resistors, capacitors, inductors, diodes, transistors, integrated circuits, etc. These components play various roles in circuits, such as controlling current, storing charge, regulating voltage, amplifying signals, etc. In practical applications, electronic components need to be connected to circuit boards through welding to establish reliable electrical connections to ensure signal transmission and current flow between electronic components.

[0003] When welding electronic components, in order to facilitate welding for workers, the circuit board is usually fixed before welding the electronic components to ensure stability during welding. However, since different electronic components are often connected on the circuit board, these electronic components have different sizes, resulting in different distances between the electronic components. When welding electronic components in the gap, it is necessary to manually rotate the welding angle or remove the circuit board and manually tilt the circuit board for welding. When welding in this way, the downward pressure of the arm during welding can easily cause the circuit board to tilt, making the circuit board unstable, thereby affecting the quality of welding and the efficiency of the entire welding.

[0009] As a further improvement of the present technical solution, the blades coaxially connected to the output shaft of the servo motor are located inside the smoke treatment shell, and the top opening of the conical seat arranged at the bottom of the smoke treatment shell is matched with a second airbag ball. When the servo motor is working, the second airbag ball is away from the top opening and the top opening is in an open state. When the servo motor stops working, the second airbag ball blocks the top opening to limit the reverse flow of gas.

[0010] As a further improvement of the technical solution, locks are provided on both sides of the processing frame, which are used to fix the door panel that is rotatably connected to the processing frame. Baffles are symmetrically provided on the inner side of the door panel, and the baffles are in contact with the air pipe connected to the smoke suction head at the bottom of the smoke treatment shell, and the air pipe is in contact with the first airbag ball on the side.

[0012] As a further improvement of the present technical solution, the piston head coaxially connected to the piston rod is located inside the piston shell, and the end of the piston rod away from the piston head is in contact with the first airbag ball, so that the expanded first airbag ball can push the piston rod to move after being squeezed, and the piston head is used to transport the gas through the trachea connected to the piston shell to the strip airbag at the other end of the trachea, so that the strip airbag expands and is pushed out from the slot hole starting from the processing frame above the oblique support plate, thereby limiting the warped circuit board.

[0013] As a further improvement of the technical solution, a water inlet valve and a water outlet valve are symmetrically provided on the outside of the air pipe at the bottom of the servo motor, and water is injected into the servo motor so that the cleaned impurities fall into the water and mix with the water.

[0014] As a further improvement of the technical solution, the contact position between the auxiliary support plate and the circuit board is inclined, the auxiliary support plate is symmetrically provided with a push rod which is slidably connected to the processing frame, and the end of the push rod away from the auxiliary support plate is in contact with the first airbag ball.

[0015] As a further improvement of the technical solution, the one-way valve is opened to allow gas to pass through the air pipe to blow out the impurities on the filter plate in the opposite direction, and the other one-way valve is in a closed state.

[0016] The second object of the invention is to provide a method for operating the electronic component welding equipment with clamping feeding, characterized in that it includes the following method steps:

[0017] S1. Use the conveyor belts on both sides of the processing table to transport the electronic components to the side of the welding gun, first place the circuit board in the processing frame, and then clamp the electronic components on the circuit board through the welding gun, and support them with the oblique support plate and auxiliary support plate in the processing frame;

[0018] S2. The electronic components are welded by a welding gun. When the electronic components are pressed down, the ejector rod squeezes the first airbag ball and inflates the strip airbag with the assistance of the piston part, so that the strip airbag expands to limit the warped circuit board;

[0019] S3. At the same time, the inflated first airbag ball will also squeeze the air pipe connected to the smoke extraction head, so that the gas flow rate entering the smoke extraction head is increased, so that the smoke generated during welding is sucked into the servo motor and filtered through the filter plate, and finally discharged from the exhaust hole.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the clamping feeding electronic component welding equipment, the welding gun is used to clamp the electronic components on the conveyor belt and transport them to the processing frame, which reduces the labor intensity of the workers and improves the work efficiency. Secondly, the servo motor drives the blades to extract the smoke generated in the welding area, and passes through the filter plate inside the servo motor, and finally discharged into the air, thereby reducing the time spent around the welding area, which helps to reduce the impact of smoke on the surrounding environment and the health of workers.

[0022] 2. In the clamping-type feeding electronic component welding equipment, the inflated first airbag ball squeezes the piston rod, so that the piston rod pushes the piston head to move inside the piston shell. The piston head compresses the air into the strip airbag, and the inflated strip airbag is squeezed out from the slot hole to limit the warped circuit board, thereby maintaining the stability of the electronic components during welding and improving the quality of welding.

[0023] 3. In the clamping feeding electronic component welding equipment, at the end of welding, the gas inside the strip airbag is used to push the piston head in the opposite direction to compress the gas on one side to the disc, and then spray it out through multiple nozzles at the bottom of the disc, so as to achieve reverse cleaning of the filter plate and prevent impurities from clogging the filter plate and affecting the smoke suction efficiency.

[0024] 4. In the clamp-feed electronic component welding equipment, water is injected into the servo motor to mix the backblown impurities with water, thereby increasing the weight of the impurities and preventing the impurities from adhering to the filter plate when the smoke is sucked out again, thereby clogging the filter plate and affecting the suction effect.

[0038] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0040] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0041] like Figure 1-4As shown, a clamping feeding electronic component welding device is provided, comprising a processing table 100, and a mechanical arm 102 and a conveyor belt 103 arranged on both sides of the surface of the processing table 100, and a processing frame 104 for carrying circuit boards and electronic components is provided in the middle of the upper surface of the processing table 100, and a welding gun 101 is provided next to the processing frame 104. The specific process of conveying electronic components is as follows:

[0042] After the electronic components are transported to the clamping position of the robot arm 102 through the conveyor belt 103 on one side of the processing frame 104, the circuit board is placed in the processing frame 104, and then the robot arm 102 there places the electronic components on the circuit board by clamping. After the electronic components are soldered, the electronic components that have been soldered to the circuit board are clamped onto the conveyor belt 103 by the robot arm 102 on the opposite side, thereby reducing the intensity of manual back and forth picking up of electronic components and facilitating use.

[0043] Next, the inclined support plates 106 fixedly connected on both sides of the inner wall of the processing frame 104 are inclined, and the inner wall of the processing frame 104 is also provided with auxiliary support plates 107. This makes it unnecessary to manually place the circuit board in an inclined state when soldering electronic components, and the support of the inclined support plates 106 and the auxiliary support plates 107 is also beneficial to improving the quality of welding. Compared with manually tilting the circuit board, it has a labor-saving effect and is easy to use.

[0044] Because a cavity is formed on the inner side of the door panel provided beside the processing frame 104, a smoke cleaning part 200 for absorbing smoke generated during welding is symmetrically provided in the cavity, and the first airbag ball 105 provided beside the smoke cleaning part 200 contacts the auxiliary support plate 107, and the first airbag ball 105 also abuts against the piston part 300 provided beside it, and the piston part 300 is connected to the strip airbag 310 beside the oblique support plate 106 through the trachea. When the auxiliary support plate 107 squeezes the first airbag ball 105, the cross-sectional area of ​​the trachea connected to the smoke cleaning part 200 beside the first airbag ball 105 is reduced (that is, the gas flow rate in the trachea will increase, while the air pressure will decrease), and the gas flow rate at the air inlet end of the smoke cleaning part 200 increases, so that the smoke generated by welding will be more easily taken away by the flowing gas, reducing the time it stays around the welding area. This helps to reduce the impact of smoke on the surrounding environment and the health of workers.

[0045] It can be seen that the smoke cleaning unit 200 is used to suck the smoke generated during welding, so that the smoke passes through the filter plate 109 inside the smoke cleaning unit 200 and is purified, thereby improving the air quality of the welding working environment and the health and safety of the workers, and achieving the effect of purifying the air.

[0046] Therefore, based on the above structure, Figure 5The specific structure of the smoke cleaning unit 200 is further disclosed. The smoke cleaning unit 200 includes a servo motor 201 and a smoke suction head 202. After the electronic components are placed on the circuit board, the servo motor 201 is arranged in the cavity and fixedly connected to the processing frame 104. The bottom of the smoke treatment shell 203 rotatably connected to the output shaft of the servo motor 201 is connected to the smoke suction head 202 arranged on the inner wall of the processing frame 104 through an air pipe. The smoke treatment shell 203 is fixedly connected to the processing frame 104, so that the welding area is connected to the inside of the servo motor 201 through the air pipe, so as to facilitate the subsequent suction operation.

[0047] The following cooperation Figure 7 As shown, during specific operation: the servo motor 201 drives the blade 204 coaxially connected to the output shaft to rotate, and the smoke generated during welding is sucked into the servo motor 201. After being purified by the filter plate 109 provided inside the servo motor 201, an exhaust hole is finally opened on one side of the top of the smoke treatment shell 203 to achieve the effect of purifying the air and prevent the smoke from polluting the health, safety and vision of the workers.

[0048] It should be noted that: the top opening of the conical seat 205 arranged at the bottom of the smoke treatment shell 203 is matched with the second airbag ball 110. When the servo motor 201 is working, the smoke passes through the smoke suction head 202 and the trachea, and the airflow pushes out the second airbag ball 110 at the top opening, so that the second airbag ball 110 is away from the top opening and abuts against the filter plate 109 (the top opening is in an open state at this time), and the filter plate 109 is provided with activated carbon and filter cotton, so that the smoke can be purified after passing through the filter plate 109 from around the second airbag ball 110, and finally discharged from the exhaust hole.

[0049] In order to prevent the smoke inside the servo motor 201 from flowing back when the servo motor 201 stops working, the second airbag ball 110 blocks the top opening under the action of gravity when the servo motor 201 stops working, thereby limiting the reverse flow of the gas inside the servo motor 201 and preventing the smoke inside the servo motor 201 from flowing back and contaminating the welding area.

[0050] Since the circuit board is tilted during welding, the auxiliary support plate 107 and the circuit board are in a tilted contact position, the first airbag ball 105 is fixedly connected to the processing frame 104, and locks are provided on both sides of the processing frame 104. The locks are used to fix the door panel that is rotatably connected to the processing frame 104, and baffles 108 are symmetrically provided on the inner side of the door panel. When the door panel is in contact with the processing frame 104, the baffle 108 is in contact with the air pipe connected to the smoke suction head 202 at the bottom of the smoke treatment shell 203, and the air pipe is in contact with the first airbag ball 105 on the side.

[0051] Therefore, when the worker presses the electronic components to connect with the circuit board, the auxiliary support plate 107 pushes the symmetrically arranged push rods and the processing frame 104 forward to slide, and the end of the push rod away from the auxiliary support plate 107 abuts against the first airbag ball 105, thereby squeezing the air pipe connected to the servo motor 201, thereby reducing the cross-sectional area of ​​the air pipe, increasing the flow rate of the gas, and reducing the air pressure around the smoke suction head 202 at the air inlet end. In this way, the smoke generated by welding can be more easily taken away by the flowing gas, reducing the time it stays around the welding area, thereby improving the air quality of the welding working environment and ensuring the health and safety of the workers.

[0052] The above is embodiment 1 of the present invention. Figure 6 and Figure 8 Embodiment 2 of the present invention is shown.

[0053] The first airbag ball 105 is squeezed by the push rod, and the first airbag ball 105 expands outward and inflates the strip airbag 310 through the piston part 300, so that the strip airbag 310 expands outward, and the strip airbag 310 is squeezed out from the slot opened above the inclined support plate 106, thereby squeezing one end of the circuit board on the inclined support plate 106 that is raised, so as to limit the lifting of the circuit board and electronic components and ensure the stability of the circuit board during welding.

[0054] Therefore, as described above, the specific structure of the piston part 300 is disclosed. The piston part 300 includes a piston shell 301 and a piston rod 302. The piston shell 301 is located behind the servo motor 201 and is fixedly connected to the processing frame 104. The piston shell 301 is slidably connected to the piston rod 302, and the piston head 303 coaxially connected to the piston rod 302 is located inside the piston shell 301. Therefore, the first airbag ball 105 expands outward to push out the piston rod 302 that is attached to the side, so that the piston head 303 compresses the air inside the piston shell 301 through the air pipe into the strip airbag 310, so that the strip airbag 310 expands and pushes out from the slot starting from the processing frame 104 above the oblique support plate 106, thereby squeezing the warped circuit board (at this time, the upper and lower edges of the circuit board are respectively against the strip airbag 310 and the oblique support plate 106, and cooperate with Figure 3 As shown), keep the circuit board stable, thereby improving the quality of welding.

[0055] It should be noted that: when the strip airbag 310 is inflated, in order to make the piston head 303 move smoothly, through holes are symmetrically provided on one side of the piston housing 301 and the piston rod 302 where they are slidably connected, and a one-way valve is provided in each through hole, and the bottom through hole is connected to the cavity. In this way, when the piston head 303 moves, the one-way valve in the top through hole is closed, and the one-way valve in the bottom through hole is opened, so that air enters the piston housing 301 from the bottom through hole, so as to prevent the piston housing 301 from being in a vacuum state, and the piston head 303 cannot compress the air into the strip airbag 310.

[0056] Further, through Figure 7 Embodiment 3 of the present invention is shown.

[0057] When welding is finished, a layer of impurities will adhere to the bottom of the filter plate 109 due to long-term welding, causing the filter plate 109 to be blocked, thereby affecting the smoke suction effect. Therefore, when welding is finished (the servo motor 201 stops working first, and the second airbag ball 110 blocks the top opening), the following cooperates Figure 8 As shown, the gas inside the strip airbag 310 pushes the piston head 303 to move. At this time, the one-way valve in the top through hole is opened, and the other one-way valve is closed, so that the gas reversely compressed by the piston head 303 is transported to the disc 311 through the air pipe connected to the inside of the servo motor 201, and is sprayed out through a plurality of nozzles arranged in a circle at the bottom of the disc 311, so as to clean the filter plate 109 fixedly connected to the servo motor 201 at the bottom of the nozzle, so as to prevent impurities from clogging the filter plate 109 and affecting the smoke suction effect.

[0058] However, the impurities after backblowing fall around the conical seat 205. When the smoke extraction operation is performed again, the impurities will still adhere to the bottom of the filter plate 109. Therefore, a water inlet valve and a drain valve are symmetrically provided on the outside of the air pipe at the bottom of the servo motor 201, and water is injected into the servo motor 201 to make the cleaned impurities fall into the water and mix with the water. This can increase the weight of the impurities and prevent the impurities after backblowing from adhering again, thereby ensuring the efficiency of extracting smoke.

[0059] After a period of time, the mixture of impurities and water is discharged through the drain valve, and water is injected into the servo motor 201 again.

[0060] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.

The electronic component welding equipment with clamping feeding according to claim 1 is characterized in that: When the first airbag ball (105) changes from expansion to contraction, the gas in the strip-shaped airbag (310) pushes the piston head (303) in the opposite direction to move, and the one-way valve in the through hole opens, allowing the gas to pass through the air pipe to blow out impurities on the filter plate (109) in the opposite direction, and the other one-way valve is in a closed state.

7. A method for operating an electronic component welding device including the clamping feeding device as claimed in claim 1, characterized in that: The method comprises the following steps: S1. Using conveyor belts (103) on both sides of the processing table (100) to transport the electronic components to the side of the welding gun (101), first placing the circuit board in the processing frame (104), and then clamping the electronic components on the circuit board using the welding gun (101), and supporting them with the inclined support plate (106) and the auxiliary support plate (107) in the processing frame (104); S2, welding the electronic components by using a welding gun (101), when pressing down the electronic components, the push rod squeezes the first airbag ball (105), and inflates the strip-shaped airbag (310) with the assistance of the piston part (300), so that the strip-shaped airbag (310) expands to restrict the warped circuit board; S3. At the same time, the inflated first airbag ball (105) also squeezes the air pipe connected to the fume extraction head (202), thereby increasing the flow rate of gas entering the fume extraction head (202), so that the fume generated during welding is sucked into the servo motor (201) and filtered through the filter plate (109), and finally discharged from the exhaust hole.
