Example 1

[0058] To facilitate understanding of the circuit board pulse welding machine positioning method of this embodiment, the circuit board pulse welding machine implementing this method will be described below.

[0059] Please refer to Figure 1 and Figure 2The circuit board pulse welding machine of this embodiment includes a base 100, an upper template 200, a push-pull sliding mechanism 300, and a positioning assembly. A housing 110 is mounted on the base 100, and a working space 101 is provided between the base 100 and the housing 110. The upper template 200 is mounted on the bottom of the housing 110 and located within the working space 101. A welding head 210 is mounted on the upper template 200. During use, the upper template 200 can drive the welding head 210 to press down, so that the welding head 210 contacts the product to be welded. The push-pull sliding mechanism 300 is mounted on the base 100 and includes a slider 310, a slide rail 320, and a first drive mechanism (not shown). The slider 310 is mounted on the slide rail. The slide rail 320 is located on the base 100 and can enter or leave the working space 101 along the slide rail 320 under the drive of the first drive mechanism. The slider 310 is used to place the fixture 330. The positioning assembly includes a first support rod 420, a second support rod 430, and a laser emitter 440. The first support rod 420 is vertically and rotatably mounted on the base 100. The first end of the second support rod 430 is vertically connected to the first support rod 420. The laser emitter 440 is mounted on the second end of the second support rod 430, and the emitting end of the laser emitter 440 faces the base 100. The second support rod 430 can rotate around the first support rod 420 so that the laser emitter 440 is located at the bottom of the welding head 210. The laser beam emitted by the laser emitter 440 can be a visible laser beam, or the laser beam emitted by the laser emitter 440 can be a non-visible laser beam, but the laser beam can form a spot on the target object, such as the product to be welded.

[0060] Since different products use different welding heads 210 and fixtures 330, the slider 310 only has a front-to-back positioning structure, but not a left-to-right positioning structure, so that the position of the fixture 330 can be adjusted left and right to adapt to the position of the welding head 210. When it is necessary to change to a different type of product to be welded, the welding head 210 is replaced first. Then, by rotating the first support rod 420, the laser emitter 440 is moved to the bottom of the welding head 210, and the welding head 210 triggers the laser emitter 440 to emit a laser beam or spot towards the base 100, thereby forming a visible positioning mark. Then, the fixture 330 with the product to be welded is placed on the slider 310, and the sliding mechanism 300 is pushed and pulled to send the fixture 330 into the working space 101 so that it is located below the welding head 210. At this time, the position of the fixture 330 and the stroke of the slider 310 can be adjusted left and right based on the laser beam or spot emitted by the laser emitter 440. After the adjustment is completed, the laser emitter 440 is reset to complete the positioning calibration. This embodiment can adjust the position of the fixture 330 according to the beam or spot, which helps to improve the efficiency and accuracy of the alignment between the welding head 210 and the fixture 330.

[0061] For details, please refer to Figure 2 A trigger switch 441 is provided at the upper end of the laser emitter 440, and the trigger switch 441 can abut against the welding head 210. When the laser emitter 440 moves to the bottom of the welding head 210, the welding head 210 abuts against the trigger switch 441 of the laser emitter 440, automatically activating the laser emitter 440 without manual activation. This also indicates that the laser emitter 440 is located directly below the welding head 210, thus confirming that the laser emitter 440 is correctly positioned.

[0062] In some embodiments, the trigger switch 441 is a push-button trigger switch. After the trigger switch 441 and the welding head 210 come into contact, the laser emitter 440 is activated due to the contact pressure. In other embodiments, the trigger switch 441 is a capacitive inductive switch. After the trigger switch 441 is located at the bottom of the welding head 210, the laser emitter 440 is activated due to capacitive induction.

[0063] In some embodiments, the second support rod 430 is a telescopic rod, which can extend and retract within a certain distance range, so that the laser emitter 440 can be adjusted in position within a certain distance range to meet the needs of different welding head 210 positions.

[0064] In some embodiments, please refer to Figure 2 The second end of the second support rod 430 is provided with a snap-fit ​​block 450, and the laser emitter 440 is snapped onto the snap-fit ​​block 450. The snap-fit ​​block 450 can conveniently connect the laser emitter 440 to the second support rod 430, and the laser emitter 440 is easy to disassemble, replace and maintain.

[0065] For example, the snap-fit ​​block 450 includes a first body 451. A mounting hole (not shown) is provided on a first side of the first body 451. The second end of the second support rod 430 is connected to the first body 451 through the mounting hole. A claw 452 is provided on the second side of the first body 451, and the laser emitter 440 is snapped onto the first body 451 through the claw 452. The mounting hole can be a through hole or a blind hole. During assembly, the second end of the second support rod 430 is inserted into the mounting hole. Alternatively, the mounting hole can be a threaded hole, and the second end of the second support rod 430 is threadedly connected to the first body 451 through the mounting hole.

[0066] Please refer to Figure 3 In some embodiments, a height adjustment block 460 is provided on the first support rod 420, and the first end of the second support rod 430 is connected to the height adjustment block 460. The height of the second support rod 430 relative to the base 100 can be adjusted by the height adjustment block 460, thereby adjusting the distance between the laser emitter 440 and the welding head 210.

[0067] For example, the height adjustment block 460 includes a second body 461 and an adjusting bolt 462. The second body 461 has a first through hole, through which a first support rod 420 passes. The adjusting bolt 462 is threaded onto the second body 461, and a portion of the adjusting bolt 462 extends into the first through hole. When height adjustment is required, the adjusting bolt 462 is unscrewed to disengage from the first support rod 420, the second body 461 is moved to the target height position, and then the adjusting bolt 462 is tightened to abut against the first support rod 420, thereby fixing the second body 461.

[0068] Please refer to Figure 1 In some embodiments, to improve welding efficiency, the base 100 is provided with a dual-station configuration, namely, two sets of push-pull sliding mechanisms 300, an upper template 200, and a welding head 210. Correspondingly, the number of positioning components is two. For example, the two positioning components are symmetrically mounted on the base 100.

[0069] Please refer to Figure 4 This embodiment discloses a circuit board pulse welding machine positioning method, including steps S110 to S140. It should be noted that the sequential marking of the method steps in this embodiment is only for ease of review and understanding, and should not be construed as a limitation on the order of implementation of the method steps.

[0070] S110. Place the product to be welded on a fixture 330, and place the fixture 330 on the slider 310;

[0071] S120, The slider 310 is moved along the slide rail 320 into the working space 101 by the first driving mechanism and is located below the welding head 210;

[0072] S130. By rotating the first support rod 420, the laser emitter 440 is moved to the bottom of the welding head 210 so that the welding head 210 triggers the laser emitter 440, and the laser emitter 440 emits a beam of light towards the base 100 or forms a light spot on the product to be welded.

[0073] S140. Using the laser beam emitted by the laser emitter 440 or the spot formed on the product to be welded, and the product to be welded as a positioning reference mark, adjust the position of the fixture 330.

[0074] When it is necessary to align the welding head 210 and the fixture 330, the fixture 330 placed on the slider 310 is moved into the workspace 101, and the laser emitter 440 is moved to the bottom of the welding head 210. The laser emitter 440 emits a beam of light towards the base 100. The position of the fixture 330 can be adjusted according to the beam or spot, which helps to improve the efficiency and accuracy of aligning the welding head 210 and the fixture 330.

[0075] Please refer to Figure 1 The first support rod 420 is vertically rotatably mounted on the base 100. Step S130, which moves the laser emitter 440 to the bottom of the welding head 210, includes: rotating the first support rod 420 so that the second support rod 430 and the laser emitter 440 rotate around the first support rod 420 to move the laser emitter 440 to the bottom of the welding head 210.

[0076] The second support rod 430 is a telescopic rod. Step S130, which moves the laser emitter 440 to the bottom of the welding head 210, also includes: adjusting the length of the second support rod 430 to move the laser emitter 440 to the bottom of the welding head 210.

[0077] Please refer to Figure 3 The first support rod 420 is provided with a height adjustment block 460, and the first end of the second support rod 430 is connected to the height adjustment block 460. Step S130, which moves the laser emitter 440 to the bottom of the welding head 210, also includes: adjusting the position of the second support rod 430 on the first support rod 420 by means of the height adjustment block 460, so as to move the laser emitter 440 to the bottom of the welding head 210. Example 2

[0078] This embodiment of the circuit board pulse soldering machine uses a dual-station device as an example. Please refer to [link / reference]. Figure 5 and Figure 6This embodiment of the circuit board pulse welding machine includes a base 100, an upper template 200, a push-pull sliding mechanism 300, and a positioning assembly. A housing 110 is mounted on the base 100, and a working space 101 is provided between the base 100 and the housing 110. There are two upper templates 200, which are respectively installed on the left and right sides of the bottom of the housing 110 and located within the working space 101. Each upper template 200 is equipped with a welding head 210. During use, the upper template 200 can drive the welding head 210 to press down, so that the welding head 210 contacts the product to be welded. There are two push-pull sliding mechanisms 300, which are mounted on the base 100 and adapted to the positions of the two upper templates 200. Each push-pull sliding mechanism 300 includes a slider 310, a slide rail 320, and a first drive mechanism (not shown). The slider 310 is mounted on the slide rail 320 and can enter or leave the working space 101 along the slide rail 320 under the drive of the first drive mechanism. The slider 310 is used to place the fixture 330. The positioning assembly includes a transverse moving mechanism 410, a first support rod 420, a second support rod 430 and a laser emitter 440. The transverse moving mechanism 410 is mounted on the housing 110. The first support rod 420 is vertically mounted on the transverse moving mechanism 410. The first end of the second support rod 430 is vertically connected to the first support rod 420. The laser emitter 440 is mounted on the second end of the second support rod, and the emitting end of the laser emitter 440 faces the base 100. The arrangement direction of the transverse moving mechanism 410 is the same as the arrangement direction of the two upper templates 200, so that the laser emitter 440 can move to the bottom of the welding head 210. The laser beam emitted by the laser emitter 440 can be a visible laser beam, or it can be a non-visual laser beam, but the laser beam can form a spot on the target object, such as the product to be welded.

[0079] To improve welding efficiency, the base 100 in this embodiment is equipped with a dual-station configuration, namely a first station and a second station distributed on the left and right sides. The configuration of the first station and the second station is identical. The first station includes an upper template 200 located on the left, a push-pull sliding mechanism 300, and a welding head 210 mounted on the upper template 200 on the left. Since different products use different welding heads 210 and fixtures 330, the slider 310 is only equipped with a front-to-back positioning structure, but not a left-to-right positioning structure, so that the position of the fixture 330 can be adjusted left and right to adapt to the position of the welding head 210. When it is necessary to change to a different type of product to be welded, the welding head 210 is replaced first. Then, through the lateral movement mechanism 410, the first support rod 420, and the second support rod 430, the laser emitter 440 is moved to the bottom of the welding head 210. The welding head 210 triggers the laser emitter 440 to emit a laser beam or form a light spot in the direction of the base 100, thereby forming a visible positioning mark. Then, the fixture 330, containing the product to be welded, is placed on the slider 310, and the sliding mechanism 300 moves the fixture 330 into the workspace 101 so that it is positioned below the welding head 210. At this point, the position of the fixture 330 and the stroke of the slider 310 can be adjusted left and right based on the laser beam or spot emitted by the laser emitter 440. After adjustment, the laser emitter 440 is reset to complete the positioning calibration. This embodiment allows the position of the fixture 330 to be adjusted according to the beam or spot, which helps improve the efficiency and accuracy of the alignment between the welding head 210 and the fixture 330.

[0080] For details, please refer to Figure 6 A trigger switch 441 is provided at the upper end of the laser emitter 440, and the trigger switch 441 can abut against the welding head 210. When the laser emitter 440 moves to the bottom of the welding head 210, the welding head 210 abuts against the trigger switch 441 of the laser emitter 440, automatically activating the laser emitter 440 without manual activation. This also indicates that the laser emitter 440 is located directly below the welding head 210, thus confirming that the laser emitter 440 is correctly positioned.

[0081] In some embodiments, the trigger switch 441 is a push-button trigger switch. After the trigger switch 441 and the welding head 210 come into contact, the laser emitter 440 is activated due to the contact pressure. In other embodiments, the trigger switch 441 is a capacitive inductive switch. After the trigger switch 441 is located at the bottom of the welding head 210, the laser emitter 440 is activated due to capacitive induction.

[0082] In some embodiments, the second support rod 430 is a telescopic rod, which can extend and retract within a certain distance range, so that the laser emitter 440 can be adjusted in position within a certain distance range to meet the needs of different welding head 210 positions.

[0083] Please continue to refer to Figure 6 In some embodiments, a snap-fit ​​block 450 is provided at the second end of the second support rod 430, and the laser emitter 440 is snapped onto the snap-fit ​​block 450. The snap-fit ​​block 450 can conveniently connect the laser emitter 440 to the second support rod 430, and the laser emitter 440 is easy to disassemble, replace, and maintain.

[0084] For example, the snap-fit ​​block 450 includes a first body 451, a mounting hole on a first side of the first body 451, a second end of a second support rod 430 connected to the first body 451 through the mounting hole, and a claw 452 on the second side of the first body 451, through which the laser emitter 440 is snapped onto the first body 451. The mounting hole can be a through hole or a blind hole, in which the second end of the second support rod 430 is inserted during assembly; alternatively, the mounting hole can be a threaded hole, in which the second end of the second support rod 430 is threadedly connected to the first body 451.

[0085] Please continue to refer to Figure 6 In some embodiments, a height adjustment block 460 is provided on the first support rod 420, and the first end of the second support rod 430 is connected to the height adjustment block 460. The height of the second support rod 430 relative to the base 100 can be adjusted by the height adjustment block 460, thereby adjusting the distance between the laser emitter 440 and the welding head 210.

[0086] For example, the height adjustment block 460 includes a second body 461 and an adjusting bolt 462. The second body 461 has a first through hole, through which a first support rod 420 passes. The adjusting bolt 462 is threaded onto the second body 461, and a portion of the adjusting bolt 462 extends into the first through hole. When height adjustment is required, the adjusting bolt 462 is unscrewed to disengage from the first support rod 420, the second body 461 is moved to the target height position, and then the adjusting bolt 462 is tightened to abut against the first support rod 420, thereby fixing the second body 461.

[0087] In some other embodiments, the first support rod 420 is a telescopic rod, and the length of the first support rod 420 is adjusted by telescoping, thereby adjusting the height of the second support rod 430 relative to the base 100, and further adjusting the height of the laser emitter 440 relative to the base 100.

[0088] In some embodiments, the lateral movement mechanism 410 includes a guide rail 411 and a slider 412. The slider 412 is slidably mounted on the guide rail 411 and is connected to the first support rod 420. Moving the slider 412 on the guide rail 411 allows the laser emitter 440 to move between the two upper templates 200, thereby adjusting the position of the clamps 330 on the two push-pull sliding mechanisms 300.

[0089] Please refer to Figure 7 The circuit board pulse welding machine positioning method of this embodiment includes steps S210 to S240. It should be noted that the sequential marking of the method steps in this embodiment is only for ease of review and understanding, and should not be construed as a limitation on the order of implementation of the method steps.

[0090] S210. Place the product to be welded on a fixture 330, and place the fixture 330 on the slider 310;

[0091] S220, The slider 310 is moved along the slide rail 320 into the working space 101 by the first drive mechanism and is located below the welding head 210;

[0092] S230. By moving the first support rod 420 and the second support rod 430, the laser emitter 440 is moved to the bottom of the welding head 210 so that the welding head 210 triggers the laser emitter 440, and the laser emitter 440 emits a beam of light toward the base 100 or forms a light spot on the product to be welded.

[0093] S240. Using the laser beam emitted by the laser emitter 440 or the light spot formed on the product to be welded, and the product to be welded as a positioning reference mark, adjust the position of the fixture 330.

[0094] When it is necessary to align the welding head 210 and the fixture 330, the fixture 330 placed on the slider 310 is moved into the workspace 101, and the laser emitter 440 is moved to the bottom of the welding head 210. The laser emitter 440 emits a beam of light towards the base 100. The position of the fixture 330 can be adjusted according to the beam or spot, which helps to improve the efficiency and accuracy of aligning the welding head 210 and the fixture 330.

[0095] Please refer to Figure 5 and Figure 6 The first support rod 420 is mounted on the lateral moving mechanism 410, which is mounted on the housing 110. Step S230, which moves the laser emitter 440 to the bottom of the welding head 210, includes: moving the first support rod 420 and the second support rod 430 through the lateral moving mechanism 410 to move the laser emitter 440 to the bottom of the welding head 210.

[0096] In some embodiments, the second support rod 430 is a telescopic rod, and step S230 of moving the laser emitter 440 to the bottom of the welding head 210 further includes: adjusting the length of the second support rod 430 to move the laser emitter 440 to the bottom of the welding head 210.

[0097] In some embodiments, the first support rod 420 is a telescopic rod, and step S230 of moving the laser emitter 440 to the bottom of the welding head 210 further includes: adjusting the telescopic length of the first support rod 420 to move the laser emitter 440 to the bottom of the welding head 210. Example 3

[0098] Please refer to Figures 8 to 11 This embodiment of the circuit board pulse welding machine uses a dual-station device as an example. The circuit board pulse welding machine of this embodiment includes a base 100, upper templates 200, push-pull sliding mechanisms 300, and positioning components. A housing 110 is mounted on the base 100, and a working space 101 is provided between the base 100 and the housing 110. There are two upper templates 200, which are installed on the left and right sides of the bottom of the housing 110 and located within the working space 101. Each upper template 200 is equipped with a welding head 210. During use, the upper template 200 can drive the welding head 210 downwards, causing the welding head 210 to contact the product to be welded. There are two push-pull sliding mechanisms 300, which are mounted on the base 100 and positioned relative to the two... Each upper template 200 is adapted to the position of the sliding mechanism 300. Each sliding mechanism 300 includes a slider 310, a slide rail 320, and a first drive mechanism (not shown). The slider 310 is mounted on the slide rail 320 and can enter or leave the workspace 101 along the slide rail 320 under the drive of the first drive mechanism. The slider 310 is used to place the fixture 330. The positioning component includes a lateral movement mechanism 410 and a laser emitter 440. The lateral movement mechanism 410 is mounted on the housing 110, and the laser emitter 440 is mounted on the lateral movement mechanism 410. The laser emitter 440 has a first laser emission slot (not shown) and a second laser emission slot 443. The first laser emission slot faces the welding head 210, and the second laser emission slot 443 faces the slider 310. The laser beam emitted by the laser emitter 440 can be a visible laser beam, or the laser beam emitted by the laser emitter 440 can be a non-visible laser beam, but the laser beam can form a spot on the target object, such as the product to be welded.

[0099] To improve welding efficiency, the base 100 in this embodiment is equipped with a dual-station configuration, namely a first station and a second station distributed on the left and right sides. The first station and the second station have the same configuration. The first station includes an upper template 200 located on the left side, a push-pull sliding mechanism 300, and a welding head 210 mounted on the upper template 200 on the left side. Since different products use different welding heads 210 and fixtures 330, the slider 310 is only equipped with a front-to-back positioning structure, but not a left-to-right positioning structure, so that the position of the fixture 330 can be adjusted left and right to adapt to the position of the welding head 210. When it is necessary to align the welding head 210 and the fixture 330, the fixture 330, on which the product to be welded is placed, is placed on the slider 310. The laser emitter 440 is moved to a position compatible with the welding head 210 via the lateral moving mechanism 410. The laser emitter 440 emits a beam of light (i.e., the first beam) towards the welding head 210 through the first laser emission slot and a beam of light (i.e., the second beam) towards the fixture 330 through the second laser emission slot 443. The position of the fixture 330 can be adjusted according to the beam or spot, which helps improve the efficiency and accuracy of aligning the welding head 210 and the fixture 330. It should be noted that in this embodiment, the laser emitter 440 irradiates the welding head 210 and the fixture 330 with beams or spots through the first laser emission slot and the second laser emission slot 443 respectively. This eliminates the need to move the fixture 330 below the welding head 210 for positioning, making operation convenient.

[0100] In some embodiments, please refer to Figure 8 The chassis 110 is also equipped with two CCD cameras 500 whose positions are adapted to the slider 310. The lenses of the CCD cameras 500 face the slider 310. Two displays 600 are arranged on the adjacent side of the base 100, and the displays 600 are electrically connected to the CCD cameras 500. The CCD cameras 500 can magnify the image of the slider 310 or the product to be welded and display it on the displays 600. Thus, when the fixture 330 with the product to be welded is installed on the slider 310, and the beam or spot of the laser emitter 440 shines on the product to be welded, the spot on the product to be welded can be magnified and displayed on the displays 600, which is convenient for precise alignment.

[0101] Please refer to Figure 10 and Figure 11The laser emitter 440 includes a housing 444 and a first laser emitting tube and a second laser emitting tube installed within the housing 444. The position of the first laser emitting tube is adapted to the first laser emitting slot, and the position of the second laser emitting tube is adapted to the second laser emitting slot 443. The first and second laser emitting tubes can emit light beams in different directions, wherein the light beams emitted by the first and second laser emitting tubes are located in the same plane, facilitating the positioning reference of the welding head 210 and the fixture 330.

[0102] Please refer to Figure 11 The first laser emitter is connected to a first angle adjustment knob 445. The orientation of the first laser emitter can be adjusted by the first angle adjustment knob 445 so that the beam is directed toward the target position.

[0103] Please refer to Figure 10 The second laser emitter is connected to a second angle adjustment knob 446, which can be used to adjust the orientation of the second laser emitter so that the beam is directed toward the target position.

[0104] In some embodiments, the lateral movement mechanism 410 includes a slider 412, a guide rail 411, and a second drive mechanism (not shown). The slider 412 is slidably mounted on the guide rail 411 and is driven by the second drive mechanism. The second drive mechanism may be a motor and is driven by the slider 412 via a belt or a screw. Driving the slider 412 by the second drive mechanism facilitates the movement of the laser emitter 440 and allows for more precise positioning.

[0105] Please refer to Figure 8 An operation panel 120 is provided on the base 100, and a control knob 121 is provided on the operation panel 120. The control knob 121 is electrically connected to the transverse movement mechanism 410.

[0106] In some embodiments, a laser switch 122 is also provided on the operation panel 120, and the laser switch 122 is electrically connected to the laser emitter 440. The laser switch 122 on the operation panel 120 can be used to easily control the laser emitter 440 to turn on and off, avoiding touching the laser emitter 440 and causing it to tilt.

[0107] In some embodiments, a telescopic rod (not shown) is connected between the laser emitter 440 and the lateral movement mechanism 410. The height of the laser emitter 440 relative to the base 100 can be adjusted by the telescopic rod structure, thereby adjusting the position of the beam emitted by the laser emitter 440 or the spot formed.

[0108] Please refer to Figure 12The circuit board pulse welding machine positioning method of this embodiment includes steps S310 to S340. It should be noted that the sequential marking of the method steps in this embodiment is only for ease of review and understanding, and should not be construed as a limitation on the order of implementation of the method steps.
