DETAILED DESCRIPTION
[0036] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.
[0037] The first implementation method:
[0038] Figure 1-7 As shown, a high-frequency transformer pin precision soldering device includes a base and a placing table 2, a strip groove is opened on the placing table 2, a movable frame 1 is installed on the base, a clamping plate 3 is installed at the movable end of the movable frame 1, and the clamping plate 3 includes a main clamping plate 31 and an auxiliary clamping plate 32, and the main clamping plate 31 and the auxiliary clamping plate 32 are connected by a pair of cylinders 33;
[0039] Auxiliary columns 4 are installed at both ends of the main splint 31, and a through hole matching the auxiliary column 4 is opened on the auxiliary splint 32. Grating transmitters and grating receivers are installed on the two auxiliary columns 4 respectively. Pressure sensing belts 5 are laid in the middle of the opposite ends of the main splint 31 and the auxiliary splint 32, and a plurality of evenly distributed pressure sensing units are arranged on the pressure sensing belts 5.
[0040] An electric guide rail is installed at the upper end of the main splint 31, and an electric latch 34 is installed at the movable end of the electric guide rail. The movable end of the electric latch 34 is in contact with the inner surface of the main splint 31;
[0041] The bottom end of the placing table 2 is connected to the checking table 6 through a lifting platform. The checking table 6 is provided with a strip groove matching the strip hole. A plurality of equally distributed pin detection units 7 are installed in the strip groove. The pin detection unit 7 includes a U-shaped bracket 71. A laser transmitter 72 and a laser receiver 73 are respectively installed at both ends of the U-shaped bracket 71. An electric telescopic rod is connected between two adjacent pin detection units 7.
[0042] The movable frame 1 includes a lifting frame, a longitudinal guide rail is installed at the movable end of the lifting frame, a transverse guide rail is installed at the movable end of the longitudinal guide rail, and the movable end of the transverse guide rail is connected to the clamping plate 3 through a mechanical arm, which is used to drive the clamping plate 3 to rotate and tilt.
[0043] The laser beams emitted by the multiple laser emitters 72 are located in the same horizontal plane. When the multiple pin detection units 7 adjust the spacing through the electric telescopic rods, the multiple electric telescopic rods work synchronously.
[0044] The auxiliary column 4 includes a fixed column 41, the bottom end of which is slidably connected to a movable plate 42, and the fixed column 41 is provided with a limiting sliding groove matching the movable plate 42. The grating transmitter and the laser receiver are respectively installed on the two movable plates 42. When the movable plate 42 is in the initial position, the grating light beam emitted by the grating transmitter matches the lower surface of the main splint 31.
[0045] A stop column penetrating the strip-shaped hole is installed on the inspection table 6 , and the width of the stop column is smaller than the minimum set distance between the main clamping plate 31 and the auxiliary clamping plate 32 .
[0046] Before soldering, the height of the placing table 2 is set according to the soldering range of the pins, and the placing table 2 is raised by controlling the lifting table until the bottom of the transformer pin matches the laser emitted by the pin detection unit 7 when the transformer is placed on the placing table 2;
[0047] Before soldering, multiple transformers are placed on the placing table 2. The number of transformers placed on the placing table 2 matches the number of pin detection units 7, and the pins are inserted into the strip grooves. When the clamping plate 3 clamps the transformer, the lower surfaces of the main clamping plate 31 and the auxiliary clamping plate 32 are attached to the placing table 2. At this time, the maximum width of the transformers arranged in rows is detected by the grating transmitter and the grating receiver.
[0048] According to the width detection result, the cylinder 33 is controlled to work, so that the main clamping plate 31 and the auxiliary clamping plate 32 clamp the transformer, so that the transformers are arranged neatly;
[0049] Then, the clamping state is maintained and the clamping plate 3 is driven to move along the strip hole. At this time, the pins of the clamped transformer are cut off from the laser at the pin detection unit 7 during the displacement process. By detecting whether the laser beams emitted by multiple pin detection units 7 are all cut off, it is determined whether the pin states of multiple transformers meet the soldering requirements.
[0050] If the pin detection unit 7 at any position detects that the laser beam is not cut off, the electric guide rail is controlled to work, and the electric plug 34 is driven to move to the right side of the pin detection unit 7. Then, when the clamping plate 3 moves upward, the electric plug 34 presses the corresponding transformer; the corresponding transformer is separated from the clamping plate 3, and then the clamping plate 3 moves the transformer to the casting flux pool and the soldering device in turn to perform pin soldering.
[0051] During the clamping process, if the detection value of any pressure sensing unit of the pressure sensing belt 5 is lower than the set value, it is determined that the transformer size is not in compliance with the standard. At this time, the electric latch 34 is driven to move to the corresponding pressure sensing unit position, and then the transformer at this position is pressed to separate it from the clamping plate 3;
[0052] This solution can achieve rapid identification and judgment of whether the transformer pin status and transformer size are qualified when the transformer is clamped, and facilitates the removal of unqualified transformers, thereby reducing the unqualified rate of products after soldering.
[0053] Second implementation method:
[0054] Figure 8 It is shown that the present application also includes an auxiliary soldering system, which includes a processor, and a data processing module, a control module and an alarm module are connected to the processor;
[0055] In the first implementation, the auxiliary soldering system achieves full support and optimization for the precision soldering process of high-frequency transformer pins through a highly integrated module design. The following is a detailed description of the functions of each module and its relationship with the specific structure:
[0056] The data processing module receives the raw data from each sensor, processes and analyzes it, and determines abnormal conditions based on the analysis results;
[0057] Specifically, the abnormal situation judged specifically includes: the data processing module receives the detection data of the pin detection unit 7, and judges whether the pins are neat and meet the requirements;
[0058] The data of each pressure sensing unit on the pressure sensing belt 5 is received to analyze whether the transformer size is in compliance with regulations.
[0059] The data from the grating transmitter and the grating receiver are processed to determine the position deviation of the transformer during the clamping process.
[0060] The control module controls the actions of various actuators according to the results of the data processing module. The actuators include: cylinders, electric guide rails, electric latches 34, etc., to achieve precise control of the soldering process.
[0061] When the alarm module detects an abnormal situation, it will issue an audible and visual alarm to alert the operator. The abnormal situation includes: unqualified pin status, non-compliant transformer size and transformer position deviation.
[0062] A verification unit for detecting the clamping condition of the transformer is provided in the control module. The verification unit controls the operation of relevant actuators to perform transformer detection in the process of clamping the transformer on the placing table 2. After the detection, the transformer with abnormal condition is removed from the clamping plate 3 according to the analysis result of the data processing module. The specific working process of the verification unit includes: when the clamping plate 3 clamps the transformer, the grating transmitter and the receiver are controlled to detect the maximum width of the transformer; according to the width detection result, the cylinder 33 is controlled to work so that the main clamping plate 31 and the auxiliary clamping plate 32 clamp the transformer; after clamping, the clamping plate 3 is driven to reciprocate along the strip hole for a set distance. During the reciprocating motion, the pin state and the clamping state of the transformer are detected by the pin detection unit 7 and the pressure sensing belt 5. If it is detected that the laser emitted by the pin detection unit 7 is not cut off or the detection value of the pressure sensing unit is lower than the set value, the electric latch 34 is controlled to move to the corresponding position to press the unqualified transformer so that it is separated from the clamping plate 3 when the clamping plate 3 rises.
[0063] The distance of the reciprocating motion is smaller than the spacing between two adjacent pin detection units 7. Before the reciprocating motion, the position of the clamping plate 3 is adjusted so that the transformer pin is located between two adjacent pin detection units 7.
[0064] The control module of this embodiment accurately controls the actions of the electric guide rail and the electric latch 34 according to the analysis results of the data processing module, ensuring that unqualified transformers are effectively eliminated, thereby reducing the unqualified rate of products after soldering.
[0065] In summary, through close collaboration, the various modules of the auxiliary soldering system have achieved intelligent control and optimization of the precision soldering process of high-frequency transformer pins, improved the accuracy and efficiency of soldering, and reduced the product failure rate.
[0066] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
