Description

Technical Field

[0001] The utility model relates to the technical field of wave soldering, and more specifically to a wave soldering tin furnace motion system. Background Art

[0002] At present, printed circuit boards (PCB) and components are mostly soldered with wave soldering equipment. The tin furnace is the core component of the wave soldering process. The height of the tin furnace relative to the PCB determines the success or failure of the soldering result. If the tin furnace is too high, the solder wave will exceed the PCB surface, and the tin will overflow to the components, causing the PCB product to be scrapped; if the tin furnace is too low, the solder wave will be lower than the PCB surface, resulting in poor soldering quality such as empty soldering, leaking soldering, and low tin penetration rate.

[0003] In existing wave soldering equipment, the actions of the tin furnace rising, falling, entering, and exiting are controlled by four switches respectively, and due to the requirement of foolproof operation of the tin furnace, the switch needs to be pressed manually for each action. When the tin furnace needs to be pushed out of the wave soldering machine for maintenance, the "down" switch must be pressed first to lower the tin furnace to the lowest position, and then the "exit" switch must be pressed to push the tin furnace to the maintenance position; after the maintenance is completed, the "enter" switch must be pressed first to return the tin furnace to the inside of the wave soldering machine, and then the "up" switch must be pressed to raise the tin furnace to the welding working position.

[0004] However, there are currently two ways to restore the tin furnace height to the position before maintenance: the first is to install a steel ruler and a pointer to provide a visual reference position; the second is to confirm the relative distance through a fixture. The first method has a simple structure and low cost, but the visual reading error is large. The error range of different people's operations is as high as 2~3mm, and the tin furnace height error exceeds 0.5mm, which will affect the welding quality. The second method is easy to operate and has high accuracy, but it is expensive, and different tin furnace heights require different fixtures.

[0005] In summary, how to achieve accurate monitoring of the height of the tin furnace at a relatively low cost is a problem that currently needs to be solved by those skilled in the art. Utility Model Content

[0030] The utility model embodiment discloses a wave soldering tin furnace movement system, which can realize accurate detection of the tin furnace height at a relatively low cost.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] When using wave soldering equipment, it is necessary to control the height of the tin wave and the height of the tin furnace. By adjusting the relative distance between the solder and the PCB board, the best soldering conditions can be achieved. The height of the tin wave is controlled by a frequency converter. By inputting different frequencies (Hz), tin waves of different heights can be produced. This is a standard parameter. As there are no standardized parameters for the height of the tin furnace, the position can only be adjusted through manual experience, or adjusted to an approximate position first, and then fine-tuned based on the quality feedback after soldering. The above two methods have poor controllability. One requires high skills and experience of personnel, and the other requires repeated trial and error adjustments for each production, which affects industrial production efficiency.

[0033] The utility model provides a wave soldering tin furnace movement to improve automation. On the one hand, the wave soldering tin furnace movement provided by the utility model simplifies the operation of the tin furnace, and can realize that the tin furnace automatically descends and exits outside the machine by pressing a switch; and the tin furnace automatically returns to the machine by pressing the switch again, and then rises to the original working position; on the other hand, the height of the tin furnace can be digitally displayed, and the height of the tin furnace can be added as a quantitative parameter to the process.

[0034] In a specific embodiment, see Figure 1 and Figure 2The wave soldering tin furnace motion system provided by the utility model includes a tin furnace 1, a carrier 2, an origin detection device 8 and a lifting detection device 7. Among them, the structure of the tin furnace 1 can be set with reference to the conventional tin furnace 1, and no specific limitation is made here. According to the welding needs, the tin furnace 1 can adopt different specifications. The carrier 2 cooperates with the tin furnace 1, and the carrier 2 can move to drive the tin furnace 1 forward or backward. Specifically, the tin furnace 1 can be detachably matched with the carrier 2, and tin furnaces 1 of different specifications can be replaced according to different welding needs. The carrier 2 is provided with a lifting device, and the tin furnace 1 is arranged on the lifting device to be lifted and lowered under the drive of the lifting device. The structure of the lifting device can adopt a telescopic drive structure, a screw transmission structure, etc., which is not specifically limited here. The origin detection device 8 is arranged on the carrier 2, and is used to detect whether the tin furnace 1 is at a reference height. Specifically, the origin detection device 8 can be set at the reference height position, and when it detects the tin furnace 1, it indicates that the tin furnace 1 is at the reference height. The lifting detection device 7 is arranged on the carrier 2, and is used to detect the rising height of the lifting device. Therefore, the rising height detected by the lifting detection device 7 can directly reflect the height of the tin furnace 1, and the height of the tin furnace 1 can be quantified, which can be specifically quantified into a digital parameter.

[0035] By using the wave soldering tin furnace motion system provided by the utility model, when the tin furnace 1 needs to be pushed out of the wave soldering machine for maintenance or returned to the wave soldering machine for work after maintenance, the carrier 2 moves forward or backward accordingly to drive the tin furnace 1 thereon to move in and out accordingly. In addition, in the above process, the tin furnace 1 can be driven to rise and fall accordingly by the lifting device to adjust the height of the tin furnace 1. And when the tin furnace 1 returns to the inside of the wave soldering machine, the lifting device drives the tin furnace 1 to rise. When the origin detection device 8 detects that the tin furnace 1 rises to the reference height, the lifting detection device 7 can detect the rising height of the lifting device, and then when it rises to the preset height, the tin furnace 1 is located at the initial set height. In summary, the wave soldering tin furnace motion system provided by the utility model detects whether the tin furnace 1 rises to the reference height, and takes its position at the reference height as the starting point, and detects the rise of the height of the tin furnace 1 through the lifting detection device 7, so that the height of the tin furnace 1 can be restored to the set height before maintenance. It can be seen that the wave soldering tin furnace motion system provided by the utility model can not only realize the accurate detection of the height of the tin furnace 1, but also eliminates the need to manufacture jigs for different tin furnaces 1, thereby reducing the cost.

[0036] In addition, the height of the tin furnace 1 can be quantified as a digital parameter, which can not only be added to the process formula file of the PCB product for management and control, but also be connected to the customer's MES (Manufacturing Execution System) to achieve remote real-time monitoring and recording of the process technology.

[0037] In some embodiments, the lifting device is used to stop when the lifting detection device 7 detects that it has risen to a preset height, and the tin furnace 1 rises to the initial set height. That is, the action of the lifting device is controlled by the lifting detection device 7, and manual operation is not required, which reduces labor costs.

[0038] In some embodiments, the lifting device includes a lead screw 9 and a driving component connected to the lead screw 9, the driving component is used to drive the lead screw 9 to rotate, and the lead screw 9 is threadedly matched with the tin furnace 1. The driving component can specifically adopt a torque output device such as a motor. The driving component drives the lead screw 9 to rotate, and the lead screw 9 drives the tin furnace 1 to rise and fall. The lifting device adopts the lead screw 9 with a simple structure and high matching accuracy. Specifically, the lead screw 9 can extend in the vertical direction and be threadedly matched with the tin furnace 1, and the driving component can be directly connected to the lead screw 9 or indirectly connected to the lead screw 9 through other transmission parts. If the lead screw 9 extends in the vertical direction, a horizontal transmission rod 10 is set to match the lead screw 9, and the horizontal transmission rod 10 is meshed with the lead screw 9 to form a worm gear structure. The driving component is connected to the horizontal transmission rod 10 to drive the horizontal transmission rod to rotate, and the rotation of the horizontal transmission rod 10 drives the lead screw 9 to rotate, thereby driving the tin furnace 1 to rise and fall.

[0039] In some embodiments, the lifting detection device 7 includes an encoder connected to the lead screw 9. By setting the encoder to detect the rotation of the lead screw 9, the rising height of the tin pot 1 can be determined based on the thread matching parameters of the lead screw 9 and the tin pot 1. The encoder can be directly connected to the lead screw 9 to directly detect the rotation of the lead screw 9, or indirectly connected to indirectly detect the rotation of the lead screw 9, such as the encoder is connected to the horizontal transmission rod 10 matched with the lead screw 9 to detect the rotation of the horizontal transmission rod 10, thereby indirectly detecting the rotation of the lead screw 9. Specifically, before the tin pot 1 rises to the reference height, that is, when the tin pot 1 has not reached the reference height, the encoder rotates with the lead screw 9 but it is not powered, so no signal is generated. When the tin pot 1 reaches the reference height, the encoder is turned on, so that the encoder rotates with the lead screw 9 while continuously generating pulse signals to reflect the rising height of the tin pot 1. Specifically, the encoder is connected to the driving component, and the driving component stops the rising action when the lead screw 9 detected by the encoder rotates a preset angle, and the lead screw 9 rotates the preset angle corresponding to the tin pot 1 rising to the initial set height. In other embodiments, the lifting detection device 7 may also adopt a position sensor to detect the height of the tin furnace 1 .

[0040] In some embodiments, the origin detection device 8 includes an origin sensing switch, which is connected to an encoder to turn on the encoder when it is detected that the tin pot 1 has risen to a reference height. The origin sensing switch is triggered when the tin pot 1 is at the reference height, so that the origin sensing switch is actuated to turn on the encoder. The origin sensing switch can be arranged in the control circuit of the encoder. When the origin sensing switch is not triggered, it is in an off state, and the encoder is not powered. When the origin sensing switch is triggered, it is turned on, and the encoder is powered on to work. Through the above arrangement, automatic detection of the encoder can be achieved without manual control, thereby reducing labor costs. In other embodiments, the origin detection device 8 can also use a position sensor and be connected to a controller, and the controller controls the encoder to turn on when the position sensor detects that the tin pot 1 is at the reference height.

[0041] In some embodiments, the wave soldering tin furnace motion system further includes a descending limit device 6 and / or an ascending limit device 5. The descending limit device 6 is arranged on the carrier 2 and connected to the lifting device, so that the lifting device stops when the tin furnace 1 is detected to descend to the lower limit of the height; the ascending limit device 5 is arranged on the carrier 2 and connected to the lifting device, so that the lifting device stops when the tin furnace 1 is detected to rise to the upper limit of the height. Specifically, when the tin furnace 1 is maintained, the lifting device drives the tin furnace 1 to descend. When the tin furnace 1 descends to the lowest position, the descending limit device 6 is triggered, so that the descending action of the lifting device stops, and the carrier 2 starts to retreat to transport the tin furnace 1 to the maintenance position. By setting the descending limit device 6, the automatic stop of the tin furnace 1 descending process can be achieved without manual control, thereby reducing labor costs. In addition, by setting the ascending limit device 5, the limit of the ascending limit position can be achieved on the basis of the lifting detection device 7 providing the rising height and then controlling the lifting device to stop rising, so as to avoid the risk of the lifting device rising higher than the preset height due to the failure of the lifting detection device 7 and other reasons, thereby improving the safety of the system.

[0042] In some embodiments, the descent limit device 6 includes a descent limit switch. The descent limit switch is triggered when the tin pot 1 is at the lower limit height, so that the descent limit switch is actuated, and the lifting device stops moving. That is, the descent limit switch can be set in the control circuit of the lifting device. When the descent limit switch is not triggered, it is in an on state, and the lifting device can drive the tin pot 1 to rise and fall. After the descent limit switch is triggered, it is disconnected, and the lifting device stops working. Through the above arrangement, the automatic detection of the descent process of the tin pot 1 can be achieved without manual control, thereby reducing labor costs. In other embodiments, the descent limit device 6 can also use a position sensor and be connected to a controller. The controller controls the lifting device to stop moving when the position sensor detects that the tin pot 1 is at the lower limit height. Further, the ascending limit device 5 includes an ascending limit switch. The specific working principle of the ascending limit switch is consistent with that of the descending limit switch, which will not be repeated here.

[0043] In some embodiments, a boss is provided on one side of the tin pot 1, and a mounting frame is provided on the carrier 2. An ascending limit switch and a descending limit switch are provided at the upper and lower ends of the mounting frame, respectively. There is a spacing between the ascending limit switch and the descending limit switch, and the boss is located within the spacing, that is, the boss is located between the ascending limit switch and the descending limit switch. Thus, when the tin pot 1 rises or falls driven by the lifting device, when the boss hits the ascending limit switch or the descending limit switch, the corresponding ascending limit switch or the descending limit switch is triggered.

[0044] In some embodiments, the wave soldering tin furnace motion system also includes a forward limit device 4 and / or a backward limit device 3 provided on the carrier 2. The forward limit device 4 is provided on the carrier 2 and connected to the power device of the carrier 2, so that the power device stops when the carrier 2 is detected to move to the first position; the backward limit device 3 is provided on the carrier 2 and connected to the power device of the carrier 2, so that the power device stops when the carrier 2 is detected to move to the first position, wherein the first position is different from the second position. Taking the forward limit device 4 as an example, when the carrier 2 moves to drive the tin furnace 1 to move forward to the first position, the forward limit device 4 is triggered, so that the carrier 2 stops moving forward, and the tin furnace 1 is transported to the first position. By setting the forward limit device 4, the automatic stop of the forward process of the tin furnace 1 can be achieved without manual control, thereby reducing labor costs. The specific working principle of the backward limit device 3 is consistent with the forward limit device 4, which will not be repeated here. As set up above, the tin furnace 1 can be automatically lifted and lowered with one button, and its simple operation method greatly improves the convenience of equipment maintenance and shortens the maintenance time.

[0045] In some embodiments, the first position corresponds to the working position of the tin furnace 1, and the second position corresponds to the maintenance position of the tin furnace 1. This realizes the automatic switching of the working position and the maintenance position of the tin furnace 1, reducing labor costs. In other embodiments, according to the different states of the tin furnace 1, the first position and the second position can also be set in other ways, such as storage positions.

[0046] In some embodiments, the forward limit device 4 includes a forward limit switch; the backward limit device 3 includes a backward limit switch. The forward limit switch is triggered when the carrier 2 advances to the first position, so that the power device of the carrier 2 stops moving and the carrier 2 stops moving. Specifically, the forward limit switch can be set in the control circuit of the power device. When the forward limit switch is not triggered, it is in the on state, and the power device can drive the carrier 2 to move. After the backward limit switch is triggered, it is disconnected and the power device stops working. Through the above settings, it is possible to realize automatic detection and control of the forward process of the carrier 2 without manual control, thereby reducing labor costs. In other embodiments, the forward limit device 4 can also use a position sensor and be connected to the controller. The controller controls the power device to stop moving when the position sensor detects that the carrier 2 is in the first position. The backward limit device 3 includes a backward limit switch. The specific working principle of the backward limit switch is consistent with that of the forward limit switch, which will not be repeated here.

[0047] In some embodiments, the descent limit switch is connected to the carrier 2, so that when the descent limit switch is triggered, the carrier drives the tin furnace 1 to retreat, and when the retreat limit switch is triggered, the carrier stops.

[0048] In some embodiments, the forward limit switch is connected to the lifting device, so that when the forward limit switch is triggered, the lifting device drives the tin furnace to rise until the lifting detection device detects that the tin furnace has risen to an initially set height.

[0049] In some embodiments, the vehicle 2 includes a vehicle frame and running wheels arranged on the vehicle frame, a forward limiter 4 and / or a backward limiter 3 are arranged at both ends of a side wall of the vehicle frame extending in the longitudinal direction, and a lifting detection device 7 is arranged on a side wall of the vehicle frame extending in the transverse direction, wherein the longitudinal direction is the front-to-back direction of the vehicle 2, and the transverse direction is perpendicular to the longitudinal direction. The forward limiter 4, the backward limiter 3 and the lifting detection device 7 are arranged in a reasonable layout as described above, and effective detection can be achieved while achieving effective use of space.

[0050] Furthermore, the two longitudinal side walls of the frame are convex-shaped, and a mounting seat is provided at the upper end of the convex shape with a smaller width, the upward limit switch and the downward limit switch are provided on the mounting seat, and the forward limit device 4 and the backward limit device 3 are provided at the two ends of the lower part of the convex shape with a larger width.

[0051] In order to better describe the wave soldering furnace motion system provided by the present invention, a preferred embodiment is described below.

[0052] In this embodiment, the wave soldering tin furnace motion system includes a tin furnace 1, a carrier 2, a backward limit switch, a forward limit switch, an upward limit switch, a downward limit switch, an encoder and an origin induction switch. The tin furnace 1 is connected to the carrier 2 through a lifting device, and the lifting device includes a lead screw 9 and a driving component.

[0053] During maintenance, the tin furnace 1 is driven by the lifting device to descend from the carrier 2. When the tin furnace 1 descends to the lowest position, the descending limit switch is triggered, the tin furnace 1 stops descending, and the carrier 2 starts to move backward carrying the tin furnace 1. When the carrier 2 moves backward to the maintenance position, the retreat limit switch is triggered, and the retreat of the carrier 2 stops.

[0054] After the maintenance is completed, the carrier 2 carrying the tin pot 1 starts to move forward. When the carrier 2 moves forward to the working position, the forward limit switch is triggered, the forward movement of the carrier 2 stops, and the tin pot 1 starts to rise on the carrier 2. The lead screw 9 drives the encoder to rotate. At this time, the encoder is not powered on and no signal is generated.

[0055] When the tin pot 1 rises to the reference height, the origin sensing switch is triggered, the encoder is powered on and starts working, continuously generating pulse signals, and the driving component drives the lead screw to rotate and drives the encoder to rotate. Specifically, when the encoder rotates one circle, the tin pot 1 rises 0.25mm. After the tin pot 1 rises to the initial set height, the rising action stops, and its positioning accuracy is ±0.02mm.

[0056] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0057] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
