DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Specific examples are given below.

[0031] See also Figure 1 - Figure 8 The present invention provides a PCB board welding device, comprising a welding machine body 1, a supporting base plate 2 is vertically fixed near the center of the side wall of the welding machine body 1, a slide plate groove 21 is provided on the top surface of the supporting base plate 2, a supporting slide plate 3 is slidably installed on the inner wall of the groove of the slide plate groove 21, a circular card groove 31 is provided at the center of the top surface of the supporting slide plate 3, a supporting circular plate 4 is clamped and installed on the inner wall of the groove of the circular card groove 31, a slider track 41 is provided at the center of the top surface of the supporting circular plate 4, a clamping assembly 5 is arranged inside the slider track 41, and the clamping assembly 5 is used to clamp and position the PCB board, conveyor belts 6 are installed on both sides of the outside of the supporting base plate 2 through brackets, and guide assemblies 7 are provided on both sides of one end of the supporting base plate 2 close to the conveyor belt 6, and the guide assembly 7 is used to guide the PCB board;

[0032] In order to solve the problem of high cost of the control device for position adjustment of the PCB board on the support table, such as rotation, displacement and other processes, when the PCB board needs to be welded, it is first placed above the conveyor belt 6 on one side, and the PCB board is conveyed to the support slide 3 under the conveying action of the conveyor belt 6's own structure. During this process, the guide component 7 can guide and transfer the PCB board, and move the PCB board to the support slide 3 through its rotational cooperation. The guide component 7 can adjust its own rotation speed according to the conveying efficiency of the conveyor belt 6 and the conveying efficiency of the PCB board transmitted thereon. Since the support slide 3 is slidably installed inside the slide groove 21, this allows the support slide 3 and the structure thereon to be able to move in the slide groove 21. The PCB board is relatively adjusted under the restriction, so as to achieve the purpose of unidirectional position adjustment of the PCB board entering the supporting slide plate 3. After the PCB board is transferred to the supporting slide plate 3, it is clamped and fixed by the clamping assembly 5 installed on the supporting circular plate 4. The clamping mode between the supporting circular plate 4 and the circular card groove 31 enables the relative angle of the PCB board to be adjusted by rotating the supporting circular plate 4 after the PCB board is fixed, so that the device can realize the position adjustment of the PCB board during the welding process by controlling the rotation of the guide assembly 7 or the supporting circular plate 4, so that the device can replace the control of the more expensive intelligent system by mechanical control without reducing the welding efficiency of the PCB board, thereby reducing the use cost of the device.

[0033] Further, such as Figure 3 and Figure 6 As shown, the clamping assembly 5 includes a bidirectional screw rod 51, both ends of which are fixed to the inner walls of the slider track 41 through bearings, and both ends of the bidirectional screw rod 51 are symmetrically provided with clamping plate sliders 52. The outer wall of the clamping plate slider 52 and the inner wall of the slider track 41 are engaged with each other, and a threaded hole 521 is provided on one side of the clamping plate slider 52. The threaded hole 521 and the bidirectional screw rod 51 are screwed together, and a PCB board clamping plate 522 is fixed to the top surface of one end of the clamping plate slider 52.

[0034] In order to realize the clamping and fixing of the PCB board by the clamping assembly 5, the clamping slider 52 slidably installed between the inner walls of the slider track 41 can be displaced under the restriction of the slider track 41, and the clamping slider 52 is screwed with the bidirectional screw rod 51 inside the slider track 41 through the threaded hole 521, so that the two clamping sliders 52 can be driven to move synchronously in the opposite direction during the rotation of the bidirectional screw rod 51. Because the clamping sliders 52 on both sides are symmetrically arranged at the two ends of the bidirectional screw rod 51, the rotation of the bidirectional screw rod 51 can drive the two PCB board clamps 522 to clamp and fix the PCB board at the relative center of the supporting circular plate 4, thereby realizing the clamping and fixing of the PCB board.

[0035] Further, such as Figure 6 and Figure 7 As shown, a screw cylinder 511 is fixed at the center of the outer wall of the bidirectional screw 51, and a first gear 512 is fixed at the center of the outer wall of the screw cylinder 511.

The gear bracket 531 and the supporting circular plate 4 are through-connected by bolts, and a first sprocket 532 is fixed at one end of the shaft of the second gear 53. A first motor 54 is suspended on one side of the bottom surface of the supporting circular plate 4 near the center through a bracket, and a second sprocket 541 is fixed to the outer wall of the output shaft of the first motor 54, and a chain 55 is installed between the second sprocket 541 and the first sprocket 532.

[0036] In order to provide a rotational output force for the bidirectional screw rod 51, the second sprocket 541 and the first sprocket 532 are connected by a chain 55, so that the rotational output force of the first motor 54 can drive the second gear 53 fixed by the gear bracket 531 to rotate as a whole, and the second gear 53 and the first gear 512 on the screw rod cylinder 511 are meshed with each other, so that the rotational output force of the first motor 54 can achieve the effect of driving the bidirectional screw rod 51 to rotate.

[0037] Further, such as Figure 3 and Figure 4 As shown, a threaded sleeve 32 is fixedly connected to a corner of the bottom surface of the supporting slide plate 3, and an adjusting screw 33 is installed on the internal thread of the threaded sleeve 32. One end of the adjusting screw 33 is fixed with a screw bracket 34 through a bearing, and the top surface of the screw bracket 34 is fixed to the bottom surface of the supporting slide plate 3. The other end of the adjusting screw 33 extends to the interior of the cabin of the welding machine body 1. A screw stabilizing frame 35 is slidingly sleeved on the outer wall of the adjusting screw 33 near the center, and the top surface of one side of the screw stabilizing frame 35 is fixed to the top surface of the supporting bottom plate 2.

[0038] In order to realize the displacement control of the supporting slide 3 in the slide groove 21, the screw rod bracket 34 is threadedly connected to the threaded sleeve 32 through the screw rod bracket 34 fixed under the supporting slide 3, so that the displacement of the supporting slide 3 in the slide groove 21 can be controlled by rotating the adjusting screw rod 33, and one end of the screw rod bracket 34 passes through the inside of the welding machine body 1, so that the displacement control of the supporting slide 3 can be realized by the rotation of the output part inside the welding machine body 1, wherein the screw rod stabilizing frame 35 installed on the supporting base plate 2 can increase its stability during rotation without affecting the rotation of the adjusting screw rod 33 through mutual cooperation with the outer wall of the adjusting screw rod 33, thereby increasing the rationality of the device structure.

[0039] Further, such as Figure 3 and Figure 8As shown, the guide assembly 7 includes a guide cylinder 71, the outer wall of the guide cylinder 71 is fixed to the side wall of the supporting base plate 2 through a bracket, a rotating shaft rod 72 is installed inside the guide cylinder 71, and both ends of the rotating shaft rod 72 respectively extend through the top and bottom surfaces of the guide cylinder 71, one end of the rotating shaft rod 72 supports the top of the base plate 2 and a guide dial plate 721 is fixed thereon, and the other end of the rotating shaft rod 72 supports the bottom of the base plate 2 and a first bevel gear 722 is fixed thereon.

[0040] The guide plate 721 is rotated by the guide plate 721 to move the first bevel gear 722 to the left and right sides of the guide plate 721 to move the first bevel gear 722 to the right and left sides of ...

[0041] Further, such as Figure 3 and Figure 8 As shown, a linkage bracket 73 is fixed at the center of one side of the bottom surface of the support base plate 2, and a transmission straight rod 74 is installed between the inner walls of the through hole of the linkage bracket 73. Second bevel gears 741 are fixed at both ends of the transmission straight rod 74, and the two second bevel gears 741 are respectively meshed with the two first bevel gears 722.

[0042] In order to realize the linkage of the guide plates 721 on both sides, the transmission straight rod 74 is fixed by the mutual cooperation between its outer wall and the linkage bracket 73. Without affecting its rotation, the transmission straight rod 74 meshes with the two first bevel gears 722 through the second bevel gears 741 at both ends, so that the first bevel gears 722 on both sides can perform synchronous and reverse rotational movement, thereby enabling the guide plates 721 to push away the PCB board that is expected to be contacted by synchronous and reverse rotation.

[0043] Further, such as Figure 3 and Figure 8 As shown, a third gear 75 is fixed to the edge of one side of the outer wall of the transmission straight rod 74 close to the linkage bracket 73, and a second motor 8 is fixedly connected to one side of the bottom surface of the support base plate 2. A fourth gear 81 is fixed to the outer wall of the output shaft of the second motor 8, and the fourth gear 81 and the third gear 75 are meshed with each other.

[0044] In order to provide the guide assembly 7 with a rotational output force for guiding the PCB board, the fourth gear 81 installed on the output shaft of the second motor 8 is meshed with the third gear 75 fixed to the outer wall of the transmission straight rod 74, so that the rotational output force of the second motor 8 can be converted into the rotational output force of the transmission straight rod 74, thereby providing an output force for the guide assembly 7 to guide the PCB board.

[0045] Further, such as Figure 2 and Figure 8 As shown, a bevel gear ring 42 is fixedly connected to the lower side wall of the supporting circular plate 4, and a third motor 9 is suspended by a bracket near the edge of a corner on the bottom surface of the supporting slide plate 3, and a third bevel gear 91 is fixed to the outer wall of the output shaft of the third motor 9, and the third bevel gear 91 and the bevel gear ring 42 are meshed with each other.

[0046] In order to realize the rotation of the supporting circular plate 4, the third bevel gear 91 on the output shaft of the third motor 9 meshes with the bevel gear ring 42, so that the third motor 9 can control the rotation state of the supporting circular plate 4 by controlling the on and off of the third motor 9.

[0047] Working principle: In order to solve the problem of high cost of the control device for position adjustment of the PCB board on the support table, such as rotation, displacement and other processes, when the PCB board needs to be welded, it is first placed above the conveyor belt 6 on one side, and the PCB board is conveyed to the support slide 3 under the conveying action of the conveyor belt 6's own structure. During this process, the guide component 7 can guide and transfer the PCB board, and move the PCB board to the support slide 3 through its rotational cooperation. The guide component 7 can adjust its own rotation speed according to the conveying efficiency of the conveyor belt 6 and the PCB board transmitted thereon. Since the support slide 3 is slidably installed inside the slide slot 21, this allows the support slide 3 and the structure thereon to be restricted by the slide slot 21. The PCB board is relatively adjusted in position to achieve the purpose of unidirectional position adjustment of the PCB board entering the supporting slide plate 3. After the PCB board is transferred to the supporting slide plate 3, it is clamped and fixed by the clamping assembly 5 installed on the supporting circular plate 4. The clamping mode between the supporting circular plate 4 and the circular card slot 31 enables the PCB board to be relatively adjusted in angle by rotating the supporting circular plate 4 after the PCB board is fixed, so that the device can realize the position adjustment of the PCB board during the welding process by controlling the rotation of the guide assembly 7 or the supporting circular plate 4, so that the device can replace the control of the more expensive intelligent system with mechanical control without reducing the welding efficiency of the PCB board, thereby reducing the use cost of the device. The CB board is clamped and fixed, and the clamping plate slider 52 slidably installed between the inner walls of the slider track 41 can be displaced under the restriction of the slider track 41, and the clamping plate slider 52 is screwed with the bidirectional screw rod 51 inside the slider track 41 through the threaded hole 521, so that the two clamping plate sliders 52 can be driven to move synchronously in the opposite direction during the rotation of the bidirectional screw rod 51. In addition, because the clamping plate sliders 52 on both sides are symmetrically arranged at the two ends of the bidirectional screw rod 51, the rotating bidirectional screw rod 51 can drive the two PCB board clamping plates 522 to clamp and fix the PCB board at the relative center of the supporting circular plate 4, thereby clamping and fixing the PCB board. In order to provide a rotational output force for the bidirectional screw rod 51, the second sprocket 541 and the first sprocket 532 are connected by a chain 55 so that the first sprocket 532 The rotational output force of a motor 54 can drive the second gear 53 fixed by the gear bracket 531 to rotate as a whole, and the second gear 53 and the first gear 512 on the screw cylinder 511 are meshed with each other, so that the rotational input force of the first motor 54 can achieve the effect of driving the bidirectional screw 51 to rotate. In order to realize the displacement control of the supporting slide 3 in the slide groove 21, the screw bracket 34 is threadedly connected to the threaded sleeve 32 through the screw bracket 34 fixed under the supporting slide 3, so that the displacement of the supporting slide 3 in the slide groove 21 can be controlled by rotating the adjusting screw 33, and one end of the screw bracket 34 passes through the inside of the welding machine body 1, so that the displacement control of the supporting slide 3 can be realized by the rotation of the output part inside the welding machine body 1.The screw rod stabilizing frame 35 installed on the supporting base plate 2 cooperates with the outer wall of the adjusting screw rod 33, thereby increasing the stability of the adjusting screw rod 33 during rotation without affecting the rotation of the adjusting screw rod 33, thereby increasing the rationality of the device structure.

[0048] The first gear 722 of the second end of the guide plate 721 is a gear which is fixed to the support frame 4 so that the guide plate 721 of the second end of the guide plate 721 is fixed to the support frame 4 so that the guide plate 721 of the second end of the guide plate 721 can rotate synchronously with the first gear 722 of the second end of the guide plate 721. The two first bevel gears 722 of 41 are respectively meshed with each other, so that the first bevel gears 722 on both sides can perform synchronous reverse rotational movement, thereby enabling the guide plate 721 to push away the PCB board that is expected to be contacted by synchronous reverse rotation. In order to provide the guide assembly 7 with a rotational output force for guiding the PCB board, the fourth gear 81 installed on the output shaft of the second motor 8 is meshed with the third gear 75 fixed to the outer wall of the transmission straight rod 74, so that the rotational output force of the second motor 8 can be converted into the rotational output force of the transmission straight rod 74, thereby providing the output force for the guide assembly 7 to guide the PCB board. In order to realize the rotation of the supporting circular plate 4, the third bevel gear 91 on the output shaft of the third motor 9 is meshed with the bevel gear ring 42, so that the third motor 9 can control the rotation state of the supporting circular plate 4 by controlling the opening and closing of the third motor 9.
