[0003] Welding is a very important part of electronic manufacturing. The quality of welding directly affects the quality of the product. If there is a deviation or mistake in the welding process, the performance of the product will easily fail to meet the design requirements. Therefore, the circuit board will be positioned first during welding to prevent it from moving during welding and causing deviation.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0028] It should be further explained that the drawings and implementation modes of the present invention mainly describe the concept of the present invention. On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above-mentioned specific forms and settings in a well-known manner.

[0029] When an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

[0030] The directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself. The directions or positional relationships indicated by the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0031] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.

[0032] 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, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0033] An automatic welding auxiliary device for electrical components provided by the present invention is now described.

[0034] like Figure 1 and Figure 2 As shown, an automatic welding auxiliary device for electrical components provided by an embodiment of the present invention includes a main platform 1 and a conveyor belt 2 arranged on the main platform 1, the length direction of the circuit board is perpendicular to the conveying direction of the conveyor belt 2, and the length of the circuit board is greater than the width of the conveyor belt 2; support frames 3 are arranged on both sides of the conveyor belt 2, and a driving member 31 for driving the corresponding support frame 3 to rise and fall is arranged on the main platform 1; a moving frame 32 is horizontally slidably arranged on one of the support frames 3, and a moving member 33 is arranged on the support frame 3 for driving the moving frame 32 to move toward the conveyor belt 2; the moving frame 32 is rotatably connected to a rotating plate 34 at the top near one end of the conveyor belt 2, the rotating plate 34 and the top surface of the other support frame 3 are contact surfaces with the circuit board, and a rotating component 4 for driving the rotating plate 34 to rotate is arranged on the moving frame 32; a clamping component 5 for clamping and fixing the circuit board is arranged on the main platform 1.

[0035] Specifically, in this embodiment, the driving member 31 and the moving member 33 are both cylinders, wherein the driving member 31 is vertically installed on the main platform 1, the moving member 33 is horizontally installed on the support frame 3, and the moving frame 32 is fixed to the piston rod of the moving member 33.

[0036] The present embodiment provides an automatic welding auxiliary device for electrical components. Compared with the prior art, the circuit board is transported by the conveyor belt 2. When the circuit board is transported to the welding station, the driving member 31 drives the two support frames 3 to rise at the same time. The two support frames 3 support the two ends of the circuit board and drive it to rise. The clamping assembly 5 then clamps and fixes the circuit board after the lifting. At this time, the driving member 31 drives the support frame 3 to descend to the rotating plate 34 to separate from the circuit board, so as to avoid the subsequent movement of the rotating plate 34 causing wear to the circuit board; the moving member 33 then drives the moving frame 32 to move toward the conveyor belt 2. Until the rotating plate 34 moves to the bottom of the middle part of the circuit board, the driving member 31 drives the supporting frame 3 to rise until the rotating plate 34 is in contact with the circuit board, and the clamping assembly 5 cancels the clamping of the circuit board. At this time, the rotating assembly 4 drives the rotating plate 34 and the circuit board to rotate 90°, so that the length direction of the circuit board is consistent with the conveying direction of the conveyor belt 2. At this time, the long side of the circuit board is facing the welder, reducing the distance between the farthest side of the circuit board and the welder, making it convenient for the welder to weld electrical components at various positions on the circuit board, and realizing the automatic transportation, lifting, rotation and positioning of the circuit board as a whole, thereby improving the welding efficiency of electrical components.

[0037] like Figure 1 to Figure 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0038] The clamping assembly 5 includes two mounting frames 51, two clamping cylinders 52 and two clamping plates 53. The two mounting frames 51 are arranged on the main platform 1, the clamping cylinders 52 are arranged on the corresponding mounting frames 51 and are arranged opposite to each other, the clamping plates 53 are fixed on the piston rods of the corresponding clamping cylinders 52, and the clamping plates 53 are all located directly above the conveyor belt 2.

[0039] When the circuit board needs to be clamped, the two clamping cylinders 52 are started so that the two clamping plates 53 can clamp and fix the circuit board. The structure is simple and the operation is convenient.

[0040] like Figure 3 to Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0041] The rotating assembly 4 includes a rotating shaft 41, a sprocket 42, a chain 43 and a driving motor 44. There are two rotating shafts 41 and they are vertically rotatably connected in the moving frame 32. There are two sprockets 42 and they are coaxially fixed on the corresponding rotating shafts 41. The chain 43 is engaged with the two sprockets 42. The top of the rotating shaft 41 close to the conveyor belt 2 is fixed to the rotating plate 34, and the rotating shaft 41 away from the conveyor belt 2 is connected to the output shaft of the driving motor 44. The driving motor 44 is arranged below the moving frame 32.

[0042] When the angle of the circuit board needs to be adjusted, the driving motor 44 is started to make the sprocket 42 drive the rotating shaft 41 to rotate through the chain 43, and the rotating shaft 41 drives the circuit board to rotate, thereby improving the efficiency of adjusting the angle of the circuit board.

[0043] like Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0044] The interior of the moving frame 32 is a closed space. The rotating plate 34 is provided with a plurality of air holes 341 connected to the interior of the moving frame 32 . The outside of the moving frame 32 is connected to a small air pump 321 .

[0045] When the rotating plate 34 is in contact with the bottom surface of the circuit board, the small air pump 321 is used to evacuate air from the inside of the moving frame 32, so that the air holes 341 can generate suction force on the circuit board, thereby improving the stability of the circuit board on the rotating plate.

[0046] like Figures 4 to 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0047] A rotating plate 411 is fixed on the rotating shaft 41 connected to the rotating plate 34 . A limiting plate 322 for limiting the rotating plate 411 is arranged in the moving frame 32 . The maximum rotation angle of the rotating plate 411 between the two limiting plates 322 is 90°.

[0048] The two limiting plates 322 can limit the rotation angle of the rotating plate 411 , thereby improving the accuracy of a single rotation of the rotating plate 34 and the circuit board, and facilitating the subsequent stable clamping of the circuit board by the clamping assembly 5 .

[0049] like Figure 5 to Figure 6 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0050] An automated welding auxiliary device for electrical components also includes an angle sensor, a controller and an alarm. The angle sensor is arranged on a rotating shaft 41 connected to a rotating plate 34. The output end of the angle sensor is connected to the input end of the controller, and the output end of the controller is connected to the alarm. The angle sensor is used to detect the single rotation angle of the corresponding rotating shaft 41 and output an angle signal. The controller is used to receive the angle signal, and when the angle value of the angle signal exceeds 90°, the controller outputs a warning signal, and the alarm issues an alarm when receiving the warning signal.

[0051] The angle sensor can detect the single rotation angle of the rotating plate 34, and can issue an alarm through the controller and the alarm when the single rotation exceeds 90°, so as to timely inspect and repair the drive motor 44, the limit plate 322 or the rotating plate 411.

[0052] like Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0053] A supporting mechanism 6 for providing real-time support to the supporting frame 3 connected with the moving frame 32 is provided on the main platform 1 . The supporting mechanism 6 is located below the supporting frame 3 on the side close to the conveyor belt 2 .

[0054] After the moving member 33 drives the moving frame 32 to move toward the conveyor belt 2, the gravity of the support frame 3 close to the conveyor belt 2 is larger, and the support mechanism 6 can support this side of the support frame 3, thereby improving the stability of the driving member 31 and the support frame 3.

[0055] like Figure 7 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0056] The supporting mechanism 6 includes a screw 61, a screw sleeve 62, a ratchet 63, a pawl 64 and a separation assembly 65. The screw sleeve 62 is vertically fixed under the corresponding supporting frame 3. The screw sleeve 62 is rotatably connected to the main platform 1 and is threadedly connected to the screw 61. The lifting and lowering of the screw 61 drives the screw sleeve 62 to rotate; the ratchet 63 is coaxially arranged on the screw sleeve 62. When the pawl 64 is engaged with the ratchet 63, the screw 61 can only move upward; the separation assembly 65 is used to cancel the steering restriction of the ratchet 63 and the pawl 64 on the screw sleeve 62.

[0057] When the driving member 31 drives the support frame 3 to rise, the support frame 3 drives the screw rod 61 to rise together, and the screw rod 61 drives the screw sleeve 62 and the ratchet 63 to rotate. The pawl 64 can have a one-way restriction effect on the screw sleeve 62 through the ratchet 63, thereby improving the stability of the support frame 3 when rising; and because the one-way restriction between the ratchet 63 and the pawl 64 is affected by the shape and size of the teeth on the ratchet 63, the one-way restriction gap between the ratchet 63 and the pawl 64 can be compensated through the threaded friction fit between the screw rod 61 and the screw sleeve 62, thereby further improving the one-way restriction effect on the support frame 3.

[0058] like Figure 7 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0059] The separation assembly 65 includes a separation cylinder 651 and a lifting frame 652 . The separation cylinder 651 is vertically arranged on the main platform 1 . The lifting frame 652 is fixed on the piston rod of the separation cylinder 651 . The pawl 64 is arranged on the lifting frame 652 .

[0060] The lifting frame 652 is also provided with a rotating support ring 653 coaxially connected to the ratchet 63. A limit block 631 is provided on the inner circumference of the ratchet 63. An annular groove 621 is provided on the outer circumference of the screw sleeve 62 for the limit block 631 to rotate inside. A limit groove 622 is provided on the inner wall of the annular groove 621 along the vertical direction for the limit block 631 to slide into. The ratchet 63 and the pawl 64 are always in a meshing state.

[0061] When the support frame 3 needs to be lowered, the separation cylinder 651 is started to drive the lifting frame 652 to move. The lifting frame 652 drives the ratchet 63 to move by rotating the support ring 653. The limit block 631 in the ratchet 63 moves from the limit groove 622 to the annular groove 621. At this time, the screw sleeve 62 and the ratchet 63 are in a relative rotation state, so the support frame 3 and the screw rod 61 can move downward.

[0062] After the support frame 3 is completely lowered, the separation cylinder 651 is started again to move the lifting frame 652 to reset, and the limit block 631 in the ratchet 63 moves from the annular groove 621 to the limit groove 622. At this time, the screw sleeve 62 and the ratchet 63 are in a synchronous rotation state, and the support frame 3 and the screw rod 61 can only rise. The ratchet 63 and the lifting frame 652 are in a relative rotation state through the rotating support ring 653, which improves the rotation stability of the ratchet 63, and ultimately improves the efficiency of unidirectional restriction and cancellation of the unidirectional restriction of the support frame 3 and the screw rod 61.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
