Description
Technical Field
The application relates to the technical field of circuit board welding, in particular to an online spot welding machine.
Background
With the development of society, circuit boards have been commonly used in various devices. The circuit board is internally integrated with a circuit structure, various electrical elements are arranged on the circuit board and are connected into the circuit through structures such as pins, and the spot welding machine is welding equipment for fixing the pins.
The spot welding machine in the related art is usually an off-line spot welding machine, that is, the spot welding machine is not connected to an assembly line, but the circuit board needs to be manually fixed on the spot welding machine for welding operation, and the circuit board is manually taken down and conveyed to the next procedure after welding. This welding method results in low production efficiency. In order to improve the efficiency, an online spot welding machine is developed successively, namely the spot welding machine is brought into a production line, a circuit board is automatically conveyed to the spot welding machine through a conveying belt for welding, and the circuit board is conveyed to the next procedure through the conveying belt after the welding is finished.
In the soldering process, an on-line spot welder needs to place soldering tools such as soldering iron and tin feeding gun close to the circuit board, and since these tools generally require much more space than solder joints, it is usually necessary to find an area around the solder joints where enough soldering tools can pass through and to pass the soldering tools through this area to reach the vicinity of the solder joints. Since the locations of the areas on different types of circuit boards through which the bonding tool passes are not the same, it may be necessary to adjust the orientation of the bonding tool relative to the solder joint by rotation or the like.
In the related art, the orientation is usually adjusted by rotating the welding tool, but as the requirements for the welding process increase, the operation process of the welding tool becomes more and more complex, and the whole welding system including the welding tool becomes more and more complicated, in which case it becomes very difficult to add an operation mechanism for rotating the welding tool in the welding system.
It is therefore desirable to find alternative configurations for designing devices that adjust the orientation of the weld spot with the bonding tool.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The embodiment of the application discloses an online spot welding machine, which comprises a welding system 1 and a circuit board conveying system 2, as shown in fig. 1 and 2. For the convenience of transportation, debugging and protection, a housing 3 may be usually added, and the soldering system 1 and the circuit board conveying system 2 are disposed in the housing 3. It should be noted that the housing 3 is not an essential component of the spot welder, and in some cases the spot welder may not include the housing 3.
The soldering system 1 usually includes a soldering tool for soldering, and generally, the soldering tool required for implementing the existing soldering process includes a soldering iron 10 and a tin feeding gun 11, and besides, the soldering tool may further include a blower, a temperature measuring instrument, a height measuring instrument, etc., which may be selected or selected according to specific requirements. In order to be able to move the welding tools to the desired welding points, a moving mechanism for moving these welding tools needs to be provided inside the welding system 1. In general, the movement of the welding tool in the horizontal direction may be realized by providing the first translation mechanism 12 and the second translation mechanism 13, and the first translation mechanism 12 may be fixedly provided on the housing 3, or may be fixed to a ceiling, a floor, or other tools for positioning in the case where the housing 3 is not provided. The second translation mechanism 13 is connected to the first translation mechanism 12, and the second translation mechanism 13 can move along the X-axis (the X-axis is parallel to the horizontal plane) under the driving of the first translation mechanism 12. Then, the welding tool is connected to the second translation mechanism 13, so that the second translation mechanism 13 can drive the welding tool to move along the Y axis (the Y axis is parallel to the horizontal plane) perpendicular to the X axis.
In this embodiment, the bonding tool typically also needs to be moved in the vertical direction (Z-axis). In a laggard scheme, all welding tools can move along the Z axis through the same vertical moving mechanism, but with the increasingly complicated welding action process, the design scheme can not meet the requirement gradually. Therefore, two sets of vertical moving mechanisms, namely a first vertical moving mechanism 14 and a second vertical moving mechanism 15, are provided in this embodiment, the first vertical moving mechanism 14 is connected with the soldering iron 10 and drives the soldering iron 10 to move along the Z axis, and the second vertical moving mechanism 15 is connected with the tin feeding gun 11 and drives the tin feeding gun 11 to move along the Z axis. Thus, by program control, soldering iron 10 and tin feeding gun 11 can be positioned at different height positions at different times, and thus, more diversified soldering actions can be achieved.
In this embodiment, the moving processes of the first translation mechanism 12, the second translation mechanism 13, the first vertical movement mechanism 14, and the second vertical movement mechanism 15 may be limited by various mechanical structures that can be realized, such as a slide rail and a lead screw, and the power source thereof may be various power sources including pneumatic, electric, hydraulic transmission, and the like, which are not limited in this embodiment.
As shown in fig. 3 to 7, the circuit board conveying system 2 in the present embodiment includes a conveying mechanism 20, an engaging mechanism, and a rotating mechanism 22. The conveying mechanism 20 is used for fixing and conveying a circuit board (not shown in the figure), that is, the conveying mechanism 20 can fix the circuit board thereon in various feasible manners such as clamping, clamping and the like, and can drive the circuit board to move. When the conveying mechanism 20 stops moving, the circuit board is kept in a fixed position and cannot be separated from the conveying mechanism 20 freely.
The conveying mechanism 20 in the present embodiment has a conveying position and a welding position. The conveyor mechanism 20 is engageable at the delivery location with both the upstream conveyor mechanism and the downstream conveyor mechanism (neither shown because they are in-line spot welders) simultaneously or separately to facilitate the transfer of the circuit boards between the conveyor mechanism 20 and either the upstream conveyor mechanism or the downstream conveyor mechanism. In this embodiment, the connection mode between the conveying mechanism 20 and the upstream conveying mechanism and the downstream conveying mechanism is not limited, as long as the normal circulation of the circuit board can be realized.
Normally, the conveying mechanism 20 and the upstream conveying mechanism and the downstream conveying mechanism of the on-line spot welder in the assembly line are arranged in sequence along a straight line (along the Y axis in fig. 1), and in the case of the housing 3, in order to be able to be normally connected, an upstream conveying window 30 and a downstream conveying window 31 are provided on the housing 3 corresponding to the conveying mechanism 20, and the upstream conveying mechanism can be connected through the upstream conveying window 30 and the downstream conveying mechanism can be connected through the downstream conveying window 31 when the conveying mechanism 20 is at the conveying position.
Since it is necessary for an operator to reach into the inside of the casing 3 when performing equipment installation and operations such as testing and maintenance, an operation opening 32 may be provided in the casing 3, and the operation opening 32 is generally provided in a side wall adjacent to the upstream conveying window 30. In order to secure the safety in the welding operation in the production line, the operation opening 32 needs to be closed, and for this reason, a safety door 33 may be provided in the housing 3 of the present embodiment to close the operation opening 32 when necessary. The safety door 33 may be connected to an alarm system, a power supply system, etc. of the on-line spot welding machine, and when the on-line spot welding machine is started in a state where the safety door 33 does not close the operation opening 32, it may warn in an alarm or power-off manner, etc. to improve safety.
In the present embodiment, in order to avoid the complication of the structure of the welding system 1, the orientations of the welding spot and the welding tool are not adjusted by actively rotating the welding tool, but are adjusted by rotating the circuit board. The rotation of the circuit board is realized by the rotation of the conveying mechanism 20, so that the conveying mechanism 20 is required to be capable of horizontal rotation in the embodiment.
In a typical splicing fashion, the conveyor 20 would be in close proximity to either the upstream conveyor or the downstream conveyor at the point of conveyance. In this case, the horizontal rotation of the conveying mechanism 20 may be greatly interfered by the upstream conveying mechanism or the downstream conveying mechanism, and therefore, the problem of interference of the upstream conveying mechanism or the downstream conveying mechanism must be solved in order to realize the horizontal rotation of the conveying mechanism 20.
In the present exemplary embodiment, a soldering position is selected for the feed mechanism 20, which soldering position is remote from the feed position, and a soldering tool, such as a soldering iron 10, a solder gun 11, etc., within the soldering system 1 is able to perform a soldering operation on a circuit board fixed on the feed mechanism 20 when the feed mechanism 20 is in this soldering position. And the conveying mechanism 20 can perform horizontal rotation at the welding position without interference of the upstream conveying mechanism and the downstream conveying mechanism.
In this embodiment, the transfer engagement mechanism of the conveying mechanism 20 between the two positions is implemented, that is, the engagement mechanism enables the conveying mechanism 20 to be transferred between the conveying position and the welding position. While the horizontal rotation of the conveyor 20 is effected by means of a rotating mechanism 22.
In this embodiment, the welding position may be deviated from the conveying position in various directions in a three-dimensional space as long as it is ensured that the conveying mechanism 20 is not interfered by the upstream conveying mechanism and the downstream conveying mechanism when horizontally rotating at the welding position. Two schemes (i.e., scheme one and scheme two) are provided in this example for reference.
As shown in fig. 3 and 4, in the first embodiment, the welding position and the conveying position are at the same level, which means that the process of transferring the conveying mechanism 20 between the welding position and the conveying position only needs to be performed in the horizontal direction, so the engaging mechanism in the first embodiment may be a horizontal moving mechanism 21a that is specially used for moving in the horizontal direction.
In this embodiment, a certain offset may exist between the welding position and the conveying position in both the X-axis and the Y-axis, but the horizontal moving mechanism 21a needs to have the capability of moving in both the X-axis and the Y-axis dimensions, which may complicate the structure of the horizontal moving mechanism 21 a.
When the upstream conveying mechanism, the conveying mechanism 20, and the downstream conveying mechanism are arranged in sequence along the Y-axis, it is also desirable to achieve that the horizontal rotation of the conveying mechanism 20 is not interfered if the conveying mechanism 20 can be moved only along the X-axis and away from the upstream conveying mechanism and the downstream conveying mechanism. However, this movement requires the in-line spot welder to have a greater depth in the X-axis direction, which adversely affects the overall volume and weight control of the in-line spot welder.
As a preferable aspect of this embodiment, the conveying mechanism 20 may have two conveying positions at the same time, that is, an upstream conveying position and a downstream conveying position, which are arranged in order along a straight line (Y axis), and the horizontal moving mechanism may be configured to shift the conveying mechanism 20 between the welding position and the upstream/downstream conveying positions. That is, in this embodiment, when the conveying mechanism 20 is in the welding position (the rectangular area enclosed by the solid lines in fig. 5), a certain gap is formed between the conveying mechanism 20 and both the upstream conveying mechanism and the downstream conveying mechanism, so that the horizontal rotation is not interfered, and when the circuit board needs to be transferred, the conveying mechanism 20 is driven by the horizontal moving mechanism 21a to move along the Y axis to the upstream conveying position (the rectangular area enclosed by the left broken lines in fig. 5) or the downstream conveying position (the rectangular area enclosed by the right broken lines in fig. 5) so as to be engaged with the upstream conveying mechanism or the downstream conveying mechanism.
As shown in fig. 4, the horizontal movement mechanism 21a includes a tray 210a, a guide assembly 211a, and a power assembly 212 a. The rotating mechanism 22 is fixedly connected to the tray 210a, so that the rotating mechanism 22 can drive the horizontal moving mechanism 21a and the conveying mechanism 20 to rotate horizontally together. The conveying mechanism 20 is connected to the tray 210a through a guide assembly 211a and moves along the guide assembly 211a relatively, and the guide assembly 211a may be a guide rail assembly, a lead screw assembly, etc., which is not limited in this embodiment. The power assembly 212a is used for driving the conveying mechanism 20 to move relatively along the guide assembly 211a, and the power assembly 212a in this embodiment may adopt various power sources such as pneumatic, electric, hydraulic transmission, and the like, and this embodiment is not limited thereto.
It should be noted that, in this embodiment, it is also considered that the rotating mechanism 22 is disposed between the conveying mechanism 20 and the horizontal moving mechanism 21a, and in this case, the horizontal moving mechanism 21a can drive the rotating mechanism 22 and the conveying mechanism 20 to move together. The related structure can be designed and laid out by those skilled in the art according to the knowledge grasped by the skilled person, and details are not described in this embodiment.
As shown in fig. 6 and 7, in the second embodiment, the conveying position and the welding position may have a height difference in the vertical direction (Z axis), and since the conveying mechanism 20 at the welding position is at a different horizontal height from the upstream conveying mechanism and the downstream conveying mechanism, it is also possible to avoid interference of the upstream conveying mechanism and the downstream conveying mechanism with the horizontal rotation of the conveying mechanism 20 at the welding position. The engaging mechanism is a lifting mechanism 21 b.
In theory, the welding position above or below the conveying position can avoid interference of the horizontal rotation of the conveying mechanism 20 by the upstream conveying mechanism and the downstream conveying mechanism. However, since the soldering system 1 is usually located above the circuit board conveying system 2, if the soldering position is located below the conveying position, the soldering tool needs to have a larger moving distance in the Z-axis, which increases the complexity of the vertical moving mechanism and increases the cost. In the present embodiment, therefore, it is recommended that the welding position (the rectangular area surrounded by the solid line in fig. 8) be located above the conveying position (the rectangular area surrounded by the broken line in fig. 8).
In this embodiment, as shown in fig. 7, the lifting mechanism 21b may be connected to the conveying mechanism 20 via the rotating mechanism 22, and at this time, the lifting mechanism 21b drives the rotating mechanism 22 and the conveying mechanism 20 to move together. The elevating mechanism 21b may include a fixed plate 210b, a guide assembly 211b, and a power assembly 212b therein. The power assembly 212b provides power for the elevation of the fixed platter 210b, and the guide assembly 211b guides the elevation of the fixed platter 210 b. The rotating mechanism 22 is provided on the fixed disk 210b and can horizontally rotate with respect to the fixed disk 210 b. The conveying mechanism 20 is connected to the fixed disk 210b by the rotating mechanism 22. The guiding component 211b in this embodiment may be a guiding rail component, a sliding sleeve component, a screw rod component, etc., and this embodiment is not limited. The power assembly 212b may be driven by various power sources, such as pneumatic, electric, hydraulic, etc., and the present embodiment is not limited thereto.
It should be noted that, in this embodiment, it is also conceivable to connect the rotating mechanism 22 to the conveying mechanism 20 through the lifting mechanism 21b, and at this time, the rotating mechanism 20 drives the lifting mechanism 21b and the conveying mechanism 20 to rotate. The related structure can be designed and laid out by those skilled in the art according to the knowledge grasped by the skilled person, and details are not described in this embodiment.
In various embodiments of the present application, the conveying mechanism 20 may include a distance adjusting assembly 200 and two conveying belts 201, the two conveying belts 201 are arranged side by side, and the distance between the two conveying belts 201 can be changed by the distance adjusting assembly 200. No matter the conveyer belt 201 adopts the clamping mode or the clamping mode to fix the circuit board, the middle area of the circuit board needs to be left for welding operation, so the clamping or clamping object is the edge of the circuit board, and the size of the circuit board which can be fixed is determined by the distance between the two conveyer belts 201. And the distance between the two conveyer belts 201 can be adjusted by the distance adjusting assembly 200 in each embodiment of the application to fix circuit boards with different sizes, so that the online spot welding machine has stronger universality.
As shown in fig. 9, the conveying mechanism 20 of the present embodiment may have a substrate 202 for connecting with other mechanisms and the distance adjusting assembly 200. The distance adjusting assembly 200 includes a walking structure 200a and a power structure 200b, the power structure 200b is connected with the conveyer belt 201 through the walking structure 200a, the power structure 200b provides power for the walking structure 200a, and the walking structure 200a converts the power into a stroke and drives the conveyer belt 201 to move. In this embodiment, a set of distance adjusting assemblies 200 may be provided for each of the two conveyor belts 201, or one of the conveyor belts 201 may be fixed on the substrate 202, and the other conveyor belt 201 may be connected to the distance adjusting assembly 200.
For integrated control of the spot welder, a control system may be provided in the spot welder, and the control system may generally include a host computer (not shown in the figures) and a human-computer interaction device 40 (see fig. 1 and 2), and the human-computer interaction device 40 includes, but is not limited to, a display screen, a touch screen, a keyboard, a mouse, and the like. The host may be located within the housing 3 for protection and the human interaction device 40 may be secured to an outer surface of the housing 3 for operation by an operator.
In summary, the online spot welding machine provided by the embodiment of the present application avoids the structural complexity of the welding system while realizing the adjustment of the orientation of the welding spot and the welding tool.
