Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a multi-station parallel batch welding fixture for integrated circuit boards. Background Technology

[0002] Integrated circuit boards are key carriers that support integrated circuits and other electronic components, and realize electrical signal transmission and functional integration through circuit connections. In order to reduce the production difficulty of integrated circuit boards and improve production efficiency, multi-station batch welding fixtures are usually used to assist in soldering and fixing electronic components such as LED beads onto integrated circuit boards.

[0003] A search revealed that utility model patent CN222094944U discloses a circuit board welding fixture, including a mounting plate. The surface of the mounting plate has a mounting groove with a shape matching the circuit board. The mounting groove has mounting holes for placing LED beads. Through slots are formed on both sides of the mounting groove along its length. The bottom of the through slots is lower than the bottom of the mounting groove. This utility model has the following advantages: When in use, multiple LED beads are first connected to the circuit board, and then the circuit board and LED beads are inverted in the mounting groove. At this time, the circuit board and LED beads are fixed, and the operator can easily weld each LED bead in sequence. The operation can be completed by only one operator, which has the characteristics of saving labor, simple operation, short operation time, and high work efficiency.

[0004] However, due to structural limitations, the aforementioned welding fixture cannot complete the batch output of circuit boards after welding. Operators must remove multiple circuit boards one by one, which affects the overall welding efficiency and still results in high labor costs.

[0005] Therefore, it is necessary to invent a multi-station parallel integrated circuit board batch welding fixture to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-station parallel integrated circuit board batch welding fixture. After batch welding is completed, integrated circuit boards from multiple stations can be output in batches, thereby avoiding the problems of high labor costs and reduced overall welding efficiency caused by manually removing them one by one. This solves the problem mentioned in the background art that due to structural limitations, existing welding fixtures cannot complete the batch output of circuit boards after welding, and operators can only remove multiple circuit boards one by one, which affects the overall welding efficiency and still results in high labor costs.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a multi-station parallel integrated circuit board batch welding fixture, comprising:

[0008] A circuit board positioning assembly is used to support and position multiple integrated circuit boards equipped with LED beads.

[0009] A synchronous lifting mechanism, comprising multiple lifting plates slidably disposed within adjacent receiving slots, a lever plate fixedly disposed at the front end of each lifting plate, and a rotating shaft fixedly connected to the rear end of each lifting plate; and

[0010] A rotary reset mechanism includes a rotating shaft that is rotatably nested inside the mounting channel via a bearing. Both ends of the rotating shaft are fixedly sleeved with annular lugs, and reset torsion springs are fixedly connected between the annular lugs and the inner wall of the adjacent mounting channel.

[0011] According to at least one embodiment of the present disclosure, a multi-station parallel integrated circuit board batch welding fixture is provided, wherein the circuit board positioning assembly includes a fixture plate, and multiple sets of circuit board positioning slots A and circuit board positioning slots B are uniformly formed on the top of the fixture plate, wherein any one of the circuit board positioning slots A cooperates with the adjacent circuit board positioning slot B to position the integrated circuit board.

[0012] According to at least one embodiment of the present disclosure, a multi-station parallel integrated circuit board batch welding fixture is provided on the top of the fixture plate with a plurality of mutually parallel receiving slots, any one of the receiving slots being located between adjacent circuit board positioning slot A and circuit board positioning slot B.

[0013] According to at least one embodiment of the present disclosure, a multi-station parallel integrated circuit board batch welding fixture is provided, wherein each of the circuit board positioning slots B has a plurality of lamp bead positioning holes that are distributed in a straight line and adapted to the lamp beads.

[0014] According to at least one embodiment of the present disclosure, a multi-station parallel integrated circuit board batch welding fixture is provided with a mounting channel through the top rear side of the fixture board, and a plurality of the receiving slots are all connected to the mounting channel.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention incorporates a synchronous lifting mechanism and a rotary reset mechanism. After batch soldering of integrated circuit boards at multiple workstations, the lifting plate is moved upwards. At this time, the lifting plate drives the dial plates located inside multiple receiving slots to rotate continuously around the rotation axis. During this process, multiple integrated circuit boards are moved out from the inner sides of adjacent circuit board positioning slots A and B by the dial plates, and then slid backwards along the dial plates that are tilted due to rotation. Compared with the prior art, this invention can batch output integrated circuit boards from multiple workstations after batch soldering, thereby avoiding the problems of high labor costs and reduced overall soldering efficiency caused by manually removing them one by one.

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1This is a schematic diagram of the overall structure of a multi-station parallel integrated circuit board batch welding fixture according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the circuit board positioning assembly 1 of a multi-station parallel integrated circuit board batch welding fixture according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the synchronous lifting mechanism 2 and the rotary reset mechanism 3 of a multi-station parallel integrated circuit board batch welding fixture according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the multi-station parallel integrated circuit board batch welding fixture disclosed herein may include components such as: circuit board positioning assembly 1, synchronous lifting mechanism 2, and rotary reset mechanism 3.

[0030] like Figure 2 As shown in this disclosure, the circuit board positioning assembly 1 includes a fixture plate 11. The top of the fixture plate 11 is evenly provided with multiple sets of circuit board positioning slots A12 and circuit board positioning slots B13. Any one of the circuit board positioning slots A12 cooperates with the adjacent circuit board positioning slot B13 to position the integrated circuit board. The top of the fixture plate 11 is provided with multiple parallel receiving slots 14. Any one of the receiving slots 14 is located between the adjacent circuit board positioning slots A12 and B13. The inner side of any one of the circuit board positioning slots B13 is provided with multiple lamp bead positioning holes 15 that are distributed in a straight line and adapted to the lamp beads. The rear side of the top of the fixture plate 11 is provided with a through mounting channel 16, and the multiple receiving slots 14 are all connected to the mounting channel 16.

[0031] Therefore, multiple soldering stations for positioning integrated circuit boards are formed by using multiple sets of circuit board positioning slots A12 and B13. When assembling integrated circuit boards, multiple LEDs are first placed into the matching LED positioning holes 15 in sequence, with the LED pins facing upwards. Then, multiple integrated circuit boards are placed into the soldering stations formed by multiple sets of circuit board positioning slots A12 and B13 for positioning. During this process, the LED pins pass through the integrated circuit boards.

[0032] like Figure 3 As shown, in a preferred embodiment, the synchronous lifting mechanism 2 includes a plurality of lifting plates 21 slidably disposed inside adjacent receiving slots 14, a lever 22 fixedly disposed at the front end of the plurality of lifting plates 21, and the rear ends of the plurality of lifting plates 21 fixedly connected to the rotating shaft 31.

[0033] Therefore, after the batch soldering of integrated circuit boards at multiple workstations is completed, the lifting plate 21 is pushed upward. At this time, the lifting plate 21 drives the dial plate 22 located inside the multiple receiving slots 14 to rotate continuously around the rotation axis 31. During this process, multiple integrated circuit boards are pushed out from the inside of the adjacent circuit board positioning slots A12 and B13 by the dial plate 22, and then slid backward along the dial plate 22 which is tilted due to rotation. Compared with the prior art, this utility model can output integrated circuit boards at multiple workstations in batches after the batch soldering is completed, thereby avoiding the problems of high labor costs and impact on overall soldering efficiency caused by manually removing them one by one.

[0034] like Figure 3 As shown in this disclosure, the rotary reset mechanism 3 includes a rotary shaft 31 that is rotatably nested inside the mounting channel 16 via a bearing. Both ends of the rotary shaft 31 are fixedly sleeved with annular ear plates 32. A reset torsion spring 33 is fixedly connected between the annular ear plates 32 and the inner wall of the adjacent mounting channel 16.

[0035] Therefore, during the process of the lever 22 driving the rotating shaft 31 to rotate, the rotating shaft 31 stores energy in the reset torsion spring 33 through the annular ear plate 32. When the lifting plate 21 is released, the stored energy in the reset torsion spring 33 drives the rotating shaft 31 to actively reset through the annular ear plate 32, and the rotating shaft 31 then drives the lever 22 and the lifting plate 21 to actively reset.

[0036] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0037] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
