Description

Technical Field

[0001] This utility model relates to the field of circuit board welding technology, and in particular to a transfer mechanism for circuit board welding. Background Technology

[0002] Circuit boards are the mechanical carriers and electrical supports of electronic components, and are an indispensable and important part of electronic equipment. Transfer mechanisms are used to move circuit boards from one workstation to another during the electronic manufacturing process. Their main purpose is to move circuit boards safely and efficiently at different stages of the soldering process, while ensuring that the circuit boards are not damaged during the transfer process.

[0003] During circuit board transportation, in order to ensure the stability and safety of the circuit boards, they are usually kept in a fixed position. However, this increases the difficulty of picking them up. In addition, if the circuit boards are not pre-processed, the soldering quality may be reduced, affecting the quality of subsequent processing. To solve the above problems, we propose a circuit board soldering transportation mechanism. Utility Model Content

[0004] The main purpose of this invention is to provide a transfer mechanism for circuit board soldering, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The circuit board welding transfer mechanism includes a base plate, with a mounting box fixedly connected to the upper end of the base plate. The front end of the mounting box is provided with an opening and closing mechanism, which includes two sets of opening and closing doors. The two sets of opening and closing doors are symmetrical to each other and are movably connected to the front end of the mounting box. The rear ends of the two sets of opening and closing doors are fixedly connected to a fixing plate. The upper ends of the two sets of fixing plates are movably connected to a placement frame. A connecting rod is movably connected between the fixing plate and the placement frame. The placement frame is movably connected to the inside of the mounting box.

[0007] Preferably, the upper end of the base plate is fixedly connected to two sets of symmetrical retaining rings, and the inner side of each set of retaining rings is equipped with a multi-stage electric actuator. The output end of the multi-stage electric actuator is fixedly connected to a connecting block, and the upper end of the connecting block is fixedly connected to the opening and closing door.

[0008] Preferably, a slider is fixedly connected to the rear end of the opening and closing door, and a sliding groove is provided at the front end of the mounting box, with the slider slidably connected to the inner side of the sliding groove.

[0009] Preferably, the inner wall of the mounting box is provided with two sets of mutually symmetrical limiting grooves, and the inner side of each of the two sets of limiting grooves is slidably connected to a limiting block, and the two sets of limiting blocks are together fixedly connected to the placement frame.

[0010] Preferably, both sets of limiting blocks have protrusions movably connected to their inner sides, and a spring is movably connected between the limiting blocks and the protrusions. Both sets of limiting grooves have two sets of positioning holes on their inner sides, and the protrusions are movably connected to the inner sides of the positioning holes.

[0011] Preferably, a storage box is installed at the upper end of the installation box, a conveying pipe is fixedly connected to the front end of the storage box, and a spray head is fixedly connected to the lower end of the conveying pipe through the installation box.

[0012] Preferably, a handle is fixedly connected to the upper end of the base plate, the handle is located on one side of the mounting box, and multiple sets of casters are installed at the lower end of the base plate.

[0013] Compared with the prior art, this utility model has the following beneficial effects: This transfer mechanism for circuit board welding opens from the front end of the mounting box through two sets of opening and closing doors, further driving the fixed plate to move. Under the connection of the connecting rod, the placement rack is pulled forward while the opening and closing doors move. At this time, under the limitation of the limiting groove, the limiting block slides inside the limiting groove, allowing the placement rack to slide out from the inside of the mounting box. At the same time, the protrusion slides out from one set of positioning holes and then slides into the inside of the limiting block, compressing the spring. When the connecting rod rotates from a vertical state to a horizontal state, the tension of the spring pushes the protrusion to slide out from the inside of the limiting block, and the protrusion slides into another set of positioning holes for engagement. Then, the rack to be placed... The circuit board to be transported is placed inside the mounting rack. Then, two sets of multi-stage electric actuators output in opposite directions, which moves the opening and closing door to its original state and pushes the mounting rack back into the mounting box. Under the action of spring extension force, the protrusion returns to its original position and engages with one of the positioning holes again, preventing the mounting rack from slipping out due to shaking during transport. Then, with the connection of the conveying pipe, a mist of flux can be sprayed onto the circuit board through the spray head to facilitate subsequent soldering. This utility model, through the opening and closing mechanism, can protect the circuit board while facilitating its handling. At the same time, the mist of flux can be sprayed during transport, reducing preparation time before soldering and thus improving production efficiency. Attached Figure Description

A fixing plate 64 is fixedly connected to the rear end of each set of opening and closing doors 61. A placement rack 68 is movably connected to the upper end of the two sets of fixing plates 64. A connecting rod 65 is movably connected between the fixing plate 64 and the placement rack 68. The placement rack 68 is movably connected to the inside of the mounting box 2.

[0023] In this embodiment, two sets of symmetrical retaining rings 3 are fixedly connected to the upper end of the base plate 1. Multi-stage electric actuators 4 are installed on the inner side of both sets of retaining rings 3. A connecting block 5 is fixedly connected to the output end of the multi-stage electric actuator 4. The upper end of the connecting block 5 is fixedly connected to the opening and closing door 61.

[0024] Specifically, by activating two sets of multi-stage electric actuators 4, two sets of connecting blocks 5 are moved, which further pushes two sets of opening and closing doors 61 to open. With the connection of connecting rods 65, the opening and closing doors 61 open at the same time, which can drive the placement rack 68 to move, allowing the placement rack 68 to slide out from the inside of the mounting box 2.

[0025] In this embodiment, a slider 62 is fixedly connected to the rear end of the opening and closing door 61, and a slide groove 63 is provided at the front end of the mounting box 2. The slider 62 is slidably connected to the inner side of the slide groove 63.

[0026] Specifically, the slider 62 is slidably connected to the inner side of the slide groove 63, and the rear end of the opening and closing door 61 is fixedly connected to the slider 62, so that the slide groove 63 can limit the opening and closing door 61.

[0027] In this embodiment, the inner wall of the mounting box 2 is provided with two sets of mutually symmetrical limiting grooves 66. The inner sides of the two sets of limiting grooves 66 are slidably connected to limiting blocks 67, and the two sets of limiting blocks 67 are fixedly connected to the placement frame 68.

[0028] Specifically, the limiting block 67 is slidably connected to the inner side of the limiting groove 66, and the two sets of limiting blocks 67 are fixedly connected to the placement rack 68, so that the limiting groove 66 can limit the placement rack 68.

[0029] In this embodiment, protrusions 69 are movably connected to the inner sides of both sets of limiting blocks 67, and springs 610 are movably connected between the limiting blocks 67 and the protrusions 69. Two sets of positioning holes 611 are opened on the inner sides of both sets of limiting grooves 66, and the protrusions 69 are movably connected to the inner sides of the positioning holes 611.

[0030] Specifically, the protrusion 69 is movably connected to the inside of the positioning hole 611, and under the action of the extension force of the spring 610, the placement rack 68 can be fixed to prevent the placement rack 68 from slipping out due to bumps during transportation.

[0031] In this embodiment, a storage box 7 is installed on the upper end of the installation box 2, a conveying pipe 8 is fixedly connected to the front end of the storage box 7, and a spray head 9 is fixedly connected to the lower end of the conveying pipe 8 through the installation box 2.

[0032] Specifically, a conveying pipe 8 is fixedly connected to the front end of the storage box 7, and a spray head 9 is fixedly connected to the lower end of the conveying pipe 8 through the mounting box 2.

[0034] Specifically, by pushing the base plate 1, the circuit board can be transferred to a designated position by rotating multiple sets of casters 11.

[0035] It should be noted that this utility model is a transfer mechanism for circuit board soldering. During use, two sets of multi-stage electric actuators 4 are activated. The positive output of the multi-stage electric actuators 4 causes the connecting block 5 to move. Then, the two sets of connecting blocks 5 drive the two sets of opening and closing doors 61 to move to the sides respectively. Simultaneously, under the limitation of the slide groove 63, the slider 62 slides inside the slide groove 63, allowing the opening and closing door 61 to open from the front end of the mounting box 2. This also drives the fixing plate 64 to move. Connected by the connecting rod 65, the movement of the opening and closing door 61 pulls the placement rack 68 forward. At this time, under the limitation of the limiting groove 66, the limiting block 67 slides inside the limiting groove 66, allowing the placement rack 68 to slide out from the inside of the mounting box 2. Simultaneously, the protrusion 69 slides out from one of the positioning holes 611 and then slides into the limiting block 67. The inner side compresses the spring 610. When the connecting rod 65 rotates from a vertical state to a horizontal state, the tension of the spring 610 pushes the protrusion 69 out of the inner side of the limiting block 67. The protrusion 69 slides into another set of positioning holes 611 for engagement. Then, the circuit board to be transferred is placed inside the placement rack 68. Subsequently, the two sets of multi-stage electric push rods 4 output in opposite directions, which can move the opening and closing door 61 to its original state. At the same time, it pushes the placement rack 68 back into the inner side of the mounting box 2. Under the action of the extension force of the spring 610, the protrusion 69 returns to its original position and engages with one of the positioning holes 611 again. Then, with the connection of the conveying pipe 8, the circuit board can be sprayed with atomized flux through the spray head 9. At the same time, the handle 10 is pushed, and the circuit board is transferred to the designated position by the rotation of multiple sets of universal wheels 11.
