Description

Technical Field

[0001] The invention relates to the technical field of electrical component welding, in particular to an electrical component welding fixture. Background Art

[0002] Electrical components are the basic units that make up the circuit and can control, convert, and transmit electrical signals. Electrical components need to be soldered to the circuit board one by one, specifically through the cooperation of the electric soldering iron gun and the solder wire, that is, the electrical components are placed in the appropriate position on the circuit board and clamped and fixed, and then the electric soldering iron gun is started to generate high temperature, and then the soldering iron is used to melt the solder wire around the electrical components to achieve welding between the electrical components and the circuit board.

[0003] When welding a small batch of electrical components on a circular circuit substrate, after the circular circuit substrate is clamped with the help of a fixture and the electrical components are placed on the circular circuit substrate to complete welding on one side, since the other sides of the electrical components are not facing the staff, especially the side facing away from the staff, the staff needs to change their position relative to the electrical components to clearly observe and weld the other sides of the electrical components. Since there are many electrical components to be welded on the circular circuit substrate, the operation is not convenient.

[0004] At the same time, some electrical components also need to be welded on the other side of the circular circuit substrate. At this time, the staff needs to operate the clamp to loosen the circular circuit substrate, flip the circular circuit substrate, and then operate the clamp to fix the circular circuit substrate, which is inconvenient. At the same time, electrical components are large and small, and electrical components are usually clamped by tweezers and placed on the circular circuit substrate. It is convenient for small electrical components, but it is not easy to clamp large electrical components stably. In addition, tweezers are needed to press the electrical components on the circular circuit substrate during welding to avoid the deviation of the electrical components, which is inconvenient to operate.

[0032] The heights of the two secondary wheels 6 are equal to that of the main wheel 3 , and the center between the two secondary wheels 6 corresponds to the center of the main wheel 3 .

[0033] The elastic component includes a square shell 16, which is fixedly connected to the output shaft end of the motor 17, and a block 25 is slidably inserted into the inner side of the square shell 16, the upper end of the block 25 is rotatably connected to the lower end of the main wheel 3, and a spring 27 is fixedly connected between the lower end of the block 25 and the inner wall of the square shell 16.

[0034] The elastic rotation mechanism includes a connecting rod 21, which is fixedly connected to the lower end of the motor 2 17, and the outer wall of the connecting rod 21 is fixedly sleeved with two connecting rings 22 in sequence from top to bottom, and the outer wall of the connecting rod 21 is rotated to sleeve two connecting plates 18 in sequence from top to bottom, the two connecting plates 18 are respectively located below the two connecting rings 22, and the two connecting plates 18 are respectively fixedly connected to the two connecting rings 22 with torsion springs 23, and the two torsion springs 23 are both slidably sleeved on the outer wall of the connecting rod 21, and the upper ends of the two connecting plates 18 are fixedly connected with support columns 7 away from the connecting rod 21, and the upper ends of the two support columns 7 are respectively connected to the lower ends of the two auxiliary wheels 6 through elastic components.

[0035] The elastic component includes a square groove 26, which is opened at the upper end of the support column 7, and a slide rod 19 is slidably inserted into the inner wall of the square groove 26, the upper end of the slide rod 19 is rotatably connected to the lower end of the secondary wheel 6, and a spring 20 is fixedly connected between the lower end of the slide rod 19 and the inner wall of the square groove 26.

[0036] In this embodiment, first, the circular circuit substrate 1 is placed in the annular grooves 14 of two adjacent secondary wheels 6 at one location, and then the bidirectional slide 9 is started. The bidirectional slide 9 can drive the two frames 11 to move closer to each other, so that the two adjacent secondary wheels 6 at one location and the two adjacent secondary wheels 6 at another location will also move closer to each other, and the single main wheels 3 at the two locations will also move closer to each other, and the circular circuit substrate 1 is supported during the process until the annular grooves 14 on the four secondary wheels 6 are all in contact with the circular circuit substrate 1. At this time, the state is as follows: Figure 1 As shown in , as the bidirectional slide 9 continues to drive the two frames 11 to move closer to each other, the four secondary wheels 6 will squeeze the circular circuit substrate 1, and the connecting plate 18 connected under each secondary wheel 6 will rotate outside the corresponding connecting rod 21, and will twist the torsion spring 23 connected to the corresponding connecting ring 22. At the same time, each secondary wheel 6 will also rotate at the upper end of the slide rod 19 until the annular grooves 14 of the two main wheels 3 are closely fitted with the circular circuit substrate 1 (the main wheel 3 and the secondary wheel 6 are made of rubber material with moderate hardness and will not clamp the circular circuit substrate 1). At this time, the circular circuit substrate 1 can be restricted and clamped, and can be suitable for different sizes.

[0037] Start the two motors 2 17, each motor 2 17 can drive the respectively connected square shell 16, block 25, spring 27 and main wheel 3 to rotate together, and the two main wheels 3 have the same direction, then under the friction between the two main wheels 3 and the circular circuit substrate 1, the circular circuit substrate 1 can be driven to rotate continuously in place between the four secondary wheels 6, then when the electrical component is clamped by the clamp mechanism and placed on the circular circuit substrate 1, and one side of the electrical component is welded by the staff with the help of the electric soldering iron gun 4 and the solder wire, the other sides of the electrical component can be turned toward the staff for welding through the rotation of the circular circuit substrate 1. When multiple electrical components are welded on the circular circuit substrate 1, the staff does not need to frequently change their position, making the welding operation more convenient.

[0038] By starting the two motors 12, the two square plates 10 can be driven to rotate. The two square plates 10 can rotate together with the two main wheels 3 and the four auxiliary wheels 6, and the circular circuit substrate 1 will also rotate until the other side of the circular circuit substrate 1 faces upward. Then, the electrical components can be quickly welded to the other side of the circular circuit substrate 1, and there is no need to disassemble the circular circuit substrate 1 during the process, making the welding operation more convenient.

[0039] Example 2: Please refer to Figure 1 as well as Figure 6 - Figure 8The present embodiment further explains the first embodiment, the clamp mechanism includes a gooseneck tube 13, the gooseneck tube 13 is fixedly connected to the lateral upper end surface of the T-shaped seat 8, and the end of the gooseneck tube 13 away from the T-shaped seat 8 is fixedly connected to the grip tube 2, the inner wall of the grip tube 2 is fixedly connected to a cross column 32, the outer wall of the cross column 32 is symmetrically slidably sleeved with a clamping plate 34, the two clamping plates 34 are fitted together, and a spring three 33 is fixedly connected between the wall surfaces away from the two clamping plates 34 and the inner wall of the grip tube 2, the two springs three 33 are slidably sleeved on the outer wall of the cross column 32, the upper edges of the side walls of the two clamping plates 34 are fixedly connected with an inclined magnetic plate 29, a magnetic block 31 is fitted between the two inclined magnetic plates 29, the side wall of the magnetic block 31 away from the two inclined magnetic plates 29 is fixedly connected with a T-shaped column 30, and the T-shaped column 30 moves through the grip tube 2.

[0040] The clamp mechanism also includes two slide grooves 35, which are respectively opened on the wall surfaces corresponding to the two clamping plates 34, and the inner walls of the two slide grooves 35 are both fitted with clamping blocks 36, and the inner walls of the two slide grooves 35 are symmetrically provided with card slots 37, and the upper edges of the two side walls of the two clamping blocks 36 are fixedly connected with rubber card blocks 38, and the four rubber card blocks 38 are respectively slidably matched with the four card slots 37.

[0041] In this embodiment, the gooseneck tube 13 is a tube that can maintain a certain fixed state after being bent in multiple directions or stretched, and has good plasticity. This is a well-known prior art and will not be described in detail. Hold the grip tube 2 and press the end of the T-shaped column 30 located on the outside of the grip tube 2 with your fingers, which will drive the T-shaped column 30 to slide in the grip tube 2, and the T-shaped column 30 will drive the magnetic block 31 to squeeze the two inclined magnetic plates 29. Under the action of the squeezing force, the two inclined magnetic plates 29 will move away from each other, thereby driving the two clamping plates 34 to slide away from each other on the outer wall of the cross column 32, and the two clamping plates 34 will squeeze the spring three 33 connected to the inner wall of the grip tube 2. Then, a larger electrical component can be placed between the two clamping plates 34 and the T-shaped column 30 can be released. Then, under the action of the spring three 33, the two clamping plates 34 can move closer to each other and clamp the larger electrical component, and the clamping is stable, and the magnetic block 31 will be squeezed and moved outward between the two inclined magnetic plates 29, the T-shaped column 30 will slide outward, and the magnetic block 31 will always be adsorbed between the two inclined magnetic plates 29.

[0042] Then, drag the grip 2 to deform the gooseneck 13 until the clamped larger electrical component is placed on the circular circuit substrate 1. Then, release the grip 2 to solder the larger electrical component with the help of an electric soldering iron gun 4 and solder wire. During the process, the larger electrical component will remain stationary to avoid displacement.

[0043] For clamping smaller electrical components, after the two clamping plates 34 move away from each other, the two clamping blocks 36 are dragged downward in sequence, and each clamping block 36 will slide down in the corresponding slide groove 35, and each clamping block 36 will drive the two rubber blocks 38 connected to it to slide down in the corresponding slot 37 until the rubber blocks 38 slide down to the bottom of the slot 37. At this time, under the friction between the rubber blocks 38 and the slot 37, the two clamping blocks 36 can maintain a certain fixed state. Since the clamping blocks 36 are much smaller in size than the clamping plates 34, the smaller electrical components can be placed between the two clamping blocks 36 and the T-shaped column 30 is loosened, so that the smaller electrical components can be well clamped. The clamping method can be adaptively switched according to the larger electrical components and the smaller electrical components, making the welding operation more convenient.

[0044] Example 3: Please refer to Figure 2 - Figure 5 This embodiment further explains the first embodiment. A support ring 15 is fixedly connected to the wall of the square plate 10 away from the motor 12. The support ring 15 is located between the main wheel 3 and the square shell 16. The support ring 15 is located on the outside of the block 25. A plurality of hemispherical blocks 1 24 are fixedly connected to the upper end of the support ring 15 in a circular array around the center. A hemispherical block 2 28 is fixedly connected to the lower edge of the main wheel 3.

[0045] In this embodiment, when the main wheel 3 rotates, it drives the hemispherical block 28 to rotate together, and the hemispherical block 28 will contact multiple hemispherical blocks 1 24 in sequence. Every time the hemispherical block 28 contacts a hemispherical block 1 24, an extrusion will be formed between the two, and the hemispherical block 28 will move up, which will drive the main wheel 3 to move up, and the main wheel 3 will drive the block 25 to slide upward in the square shell 16 and stretch the spring 27, and drive the circular circuit substrate 1 to move upward, and the circular circuit substrate 1 will drive the secondary wheel 6 to move up, and the secondary wheel 6 will drive the slide bar 19 slides upward in the corresponding square groove 26 and stretches the spring 1 20. When the hemispherical block 28 rotates away from the hemispherical block 1 24, the main wheel 3, the secondary wheel 6 and the circular circuit substrate 1 will automatically move downward under the action of the spring 27 and the spring 1 20. Then, as the hemispherical block 28 continues to rotate, the circular circuit substrate 1 will continue to shake up and down, thereby simulating the real working environment of the circular circuit substrate 1 to determine whether the electrical components are firmly welded. While clamping and welding the electrical components, it is also convenient to control the welding quality.
