Detailed Implementation

[0037] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] This embodiment provides a welding apparatus for a vehicle-mounted power amplifier, including a carrier. The circuit board of the vehicle-mounted power amplifier is mounted on the carrier, which is used to position the circuit board to facilitate the machine to weld the pins on the back of the circuit board. The vehicle-mounted power amplifier 100 includes a housing 101 and a cover plate 103 for accommodating the circuit board 102, and the cover plate 103 and the housing 101 are fixedly connected by screws.

[0039] Figures 1 to 11 A vehicle amplifier carrier according to this embodiment is shown. The carrier includes a carrier base 2, a carrier plate 1, a rotating pressure block 22, a pressure cover 3, a reinforcing strip 4, and a snap-fit ​​assembly 5.

[0040] Furthermore, the carrier seat 2 is disposed on the conveyor belt and has a receiving space 21 for accommodating the carrier piece 1. The carrier piece 1 is used to carry the circuit board 102 and is detachably connected to the carrier seat 2. The carrier piece 1 and the battery cell are of a one-to-one correspondence, which can be quickly adapted and replaced during production. That is, the carrier in this embodiment can be compatible with the production of different products. After the circuit board 102 is placed in the carrier piece 1, soldering is performed. At this time, the carrier seat 2 carries the carrier piece 1 and the circuit board 102 and flows on the automated production line.

[0041] The carrier piece 1 is made of non-metallic material, which provides excellent insulation and reduces the risk of malfunctions in some testing equipment due to electrical conductivity issues in the production line. Furthermore, the carrier piece 1 includes a first carrier piece 13, a second carrier piece 14, a third carrier piece 15, and a fourth carrier piece (not shown in the figure) spaced apart. The circuit board 102 includes a first circuit board, a second circuit board, and a third circuit board. A first station for carrying the first circuit board is formed between the first carrier piece 13 and the second carrier piece 14, with a first gap between them exposing a portion of the lower surface of the first circuit board. A second station for carrying the second circuit board is formed between the second carrier piece 14 and the third carrier piece 15, with a second gap exposing a portion of the lower surface of the second circuit board. A third station for carrying the third circuit board is formed between the third carrier piece 15 and the fourth carrier piece, with a third gap exposing a portion of the lower surface of the third circuit board. That is, the first and second circuit boards can share the intermediate second carrier piece 14, and the second and third circuit boards share the intermediate third carrier piece 15. There is a first gap 6 between the first carrier piece 13 and the second carrier piece 14, and a second gap 7 between the second carrier piece 14 and the third carrier piece 15. This not only facilitates welding, but also reduces the material used for the carrier pieces 1, saving materials and reducing production costs. In addition, there are multiple carrier pieces 1 instead of a single piece, which has the advantage of being less prone to deformation and is also more convenient in terms of processing.

[0042] A rotating pressure block 22 is mounted on the carrier base 2, and the carrier piece 1 is in an installed state, which is the state in which the carrier piece 1 is mounted on the carrier base 2. In the installed state, the rotating pressure block 22 presses against the carrier piece 1 to connect the carrier piece 1 and the carrier base 2. Specifically, the carrier base 2 is provided with a rivet stud 23, the rotating pressure block 22 is sleeved on the rivet stud 23 and the rotating pressure block 22 can rotate relative to the rivet stud 23, and a spring (not shown in the figure) is also provided between the rivet stud 23 and the rotating pressure block 22. The spring is always in a compressed state, and the spring provides a downward pressure to the rotating pressure block 22 so that it can press the carrier piece 1 tightly and prevent the carrier piece 1 from being pulled along when gripping the circuit board 102.

[0043] Combination Figure 4 and Figure 5 As shown, the carrier piece 1 is provided with a positioning pin 11, and the circuit board 102 is provided with a first positioning hole 1021. The positioning pin 11 is inserted into the first positioning hole 1021 to position the circuit board 102 on the carrier piece 1. Through the first positioning hole 1021 and the positioning pin 11, the carrier piece 1 and the circuit board 102 can be easily matched and installed, meeting the requirements of circuit board production. The pressure cover 3 is provided with a positioning post 31, and the carrier piece 1 is provided with a second positioning hole 12. The positioning post 31 is inserted into the second positioning hole 12 to position the pressure cover 3. Specifically, each pressure cover 3 is provided with four positioning posts 31, and the carrier piece 1 is provided with four corresponding second positioning holes 12. The cover 3 also has multiple cutouts 32, which can save material costs. Furthermore, the cover 3 is pressed onto multiple components 1023 on the circuit board 102 to prevent the circuit board 102 from shaking. Specifically, the cover 3 is pressed onto the components 1023 by multiple pressing assemblies 8. The pressing assembly 8 includes a pressing member 81 pressed onto the component 1023, a screw 82 set on the pressing member 81, and a spring sleeved on the outside of the screw 82. The pressing member 81 has an internal thread and the internal thread is threadedly connected to the external thread of the screw 82. The screw 82 passes through the cover 3 and can move up and down according to the height change of the component 1023. The spring plays a buffering role.

[0044] The reinforcing strip 4 is provided on the carrier piece 1 and / or the carrier base 2. Specifically, in this embodiment, refer to... Figure 5 As shown, there are three reinforcing strips 4. One reinforcing strip is set on the second carrier piece 14 and the carrier seat 2, and the other two reinforcing strips are set on the carrier seat 2. The two reinforcing strips are set in parallel. The three reinforcing strips are in the shape of "I". The purpose of setting the reinforcing strips is to prevent the carrier piece 1 or the carrier seat 2 from deforming under high temperature conditions, which would lead to abnormal welding quality. It can also be understood that the reinforcing strips 4 play the role of reinforcing ribs.

[0045] The carrier also includes a snap-fit ​​assembly 5, which is used to snap the pressure cap 3 in place to prevent deformation or loosening of the pressure cap 3. Figure 2 and Figure 9As shown, each pressure cap 3 has two opposing snap-fit ​​components 5. Each snap-fit ​​component 5 has a first pressure block 51, a second pressure block 52, and a snap-fit ​​member 53. The pressure cap 3 is located between the first pressure block 51 and the second pressure block 52. The second pressure block 52 is fixedly mounted on the carrier base 2, and the first pressure block 51 is mounted on the pressure cap 3. The snap-fit ​​member 53 is connected to the first pressure block 51 via a first connecting pin 54 and a second connecting pin 55. An elastic element 56 is sleeved on the first connecting pin 54. The snap-fit ​​component 53 has a hook 531, and the second pressing block 52 has a snap-fit ​​surface 521. When the snap-fit ​​component 5 is snapped onto the cover 3, the hook 531 snaps onto the snap-fit ​​surface 521. When it is necessary to remove the cover 3 from the snap-fit ​​component 5, the upper end of the snap-fit ​​component 53 is moved. The upper end of the snap-fit ​​component 53 rotates towards the center of the cover 3 about the second connecting pin 55 as the pivot. At this time, the elastic element 56 is compressed, the hook 531 leaves the snap-fit ​​surface 531, the snap-fit ​​component 5 loses its snap-fit ​​function on the cover 3, and the cover 3 can be detached from the snap-fit ​​component 5. The "upper end" here can be referred to as Figure 2 The up, down, left, and right directions shown in the drawing.

[0046] In this embodiment, during the assembly of the vehicle amplifier carrier, the carrier base 2 is first placed on the conveyor belt, then the carrier piece 1 is placed on the carrier base 2, followed by the circuit board 102 being placed on the carrier piece 1. Finally, the pressure cap 3 is pressed onto the circuit board 102, and the assembled carrier is then conveyed to the production stage via an automated assembly line. In this embodiment, when positioning different circuit boards, the carrier pieces 1 are detached one by one from the carrier base 2, allowing for quick replacement of the carrier pieces 1. This ensures compatibility with different vehicle amplifiers and is convenient to use. The carrier pieces 1 are independently set up, and there are multiple carrier pieces 1, making them less prone to deformation during use and easier to process. Furthermore, the carrier in the middle position can simultaneously supply two adjacent battery cells, saving materials and reducing production costs.
