Description

Technical Field

[0001] The utility model relates to the technical field of SMT equipment, in particular to a width-adjustable conveyor rack for SMT equipment. Background Art

[0002] SMT is surface assembly technology (surface mount technology), also known as surface mount or surface mounting technology. It is currently the most popular technology and process in the electronic assembly industry. The finished products of SMT technology are mainly PCB boards. PCB boards need to be transported during production and transportation, so special conveyor racks are needed.

[0003] In actual use, the existing SMT conveyor rack places the boards inside the conveyor rack and distributes them up and down. The boards are pushed to the equipment on one side by an external pushing mechanism, and then the conveyor rack is automatically lifted to facilitate the next board to move up for stocking. However, in actual use, PCB boards vary in size. One conveyor rack can only feed PCB boards of one specification, and its scope of use is limited. Therefore, to address the above problems, a conveyor rack with adjustable width for SMT equipment is proposed. Utility Model Content

[0004] The purpose of the present invention is to provide a width-adjustable conveyor rack for SMT equipment to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a width-adjustable conveyor rack for SMT equipment, comprising a conveyor rack, a placement mechanism, and a substrate;

[0006] The conveyor frame is internally provided with placement mechanisms distributed on the left and right, the outer side of the placement mechanism on one side is fixedly connected to the conveyor frame, and the outer side of the placement mechanism on the other side is slidably connected to the conveyor frame, and a plurality of substrates are arranged between the placement mechanisms;

[0007] A hydraulic rod is fixedly connected to the side of the conveying frame, and the free end of the hydraulic rod is fixedly connected to the placement mechanism;

[0008] The placing mechanism includes a placing frame, an adjusting body and a push plate. The outer side of the placing frame on one side is fixedly connected to the conveying frame, and the outer side of the placing frame on the other side is slidably connected to the conveying frame. The inner side of the placing frame is fixedly connected to the adjusting body, and the bottom of the adjusting body is fixedly connected to the push plate. The inner side of the push plate is rotatably connected to the central rotating shaft, and the outer side of the central rotating shaft is rotatably connected to the cross-arranged rotating plates, and the other ends of the rotating plates are rotatably connected to the side rotating shafts.

[0009] The outer side of the central rotating shaft is also fixedly connected with a placement plate.

[0010] Furthermore, the central rotating shaft at the bottom is rotatably connected to the placement rack.

[0011] Furthermore, a slide groove is provided inside the placement rack, and a plurality of central rotating shafts are slidably connected inside the slide groove.

[0012] In actual use, the existing SMT conveyor rack has its plates placed inside the conveyor rack and distributed up and down. The plates are pushed to the equipment on one side by an external pushing mechanism, and then the conveyor rack is automatically lifted to facilitate the next plate to move up for stocking. However, in actual use, the PCB plates are of different sizes. One conveyor rack can only transport PCB plates of one specification, and its scope of use is limited. When in use, the placement mechanism on one side is driven to move by activating the hydraulic rod according to the size of the PCB plate. At this time, the distance between the placement mechanisms on both sides can be controlled, thereby ensuring that PCB plates of different widths can be fixed, expanding the scope of use of the conveyor rack, and the rotating plate, central rotating shaft and side rotating shaft are used together to control the distance between the placement plates, which is convenient for controlling the distance between the substrates and ensuring that the substrates can be stably pushed to the next process.

[0013] Furthermore, the adjusting body includes a fixed frame, a motor and a threaded shaft. The outer side of the fixed frame is fixedly connected to the placement frame, the inner side of the fixed frame is fixedly connected to the motor, the end of the main shaft of the motor is fixedly connected to the threaded shaft, and the outer side of the threaded shaft is spirally connected to a threaded sleeve, and the bottom of the threaded sleeve is fixedly connected to the push plate.

[0014] Furthermore, a groove is provided on the side surface of the threaded sleeve, and a limiting block is provided inside the groove, and the outer side of the limiting block is fixedly connected to the fixing frame.

[0015] By starting the motor to rotate, the threaded shaft is driven to rotate. At this time, the threaded sleeve drives the push plate to move, so that the central shaft can slide inside the slide groove to control the distance between the central shafts, thereby ensuring the use range of the equipment.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When the utility model is in use, the placement mechanism on one side is moved by activating the hydraulic rod according to the size of the PCB board. At this time, the distance between the placement mechanisms on both sides can be controlled, thereby ensuring that PCB boards of different widths can be fixed, expanding the use range of the conveyor rack;

[0018] The rotating plate, central rotating shaft and side rotating shaft are used together to control the distance between the placement plates, which is convenient for controlling the distance between the substrates and ensuring that the substrates can be stably pushed to the next process.

[0019] 2. Start the motor to rotate the threaded shaft, and the threaded sleeve drives the push plate to move, so that the central shaft can slide inside the slide groove to control the distance between the central shafts, thereby ensuring the use range of the equipment.

[0024] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention. Example 1

[0025] See also Figure 1 and Figure 2 , the utility model provides a technical solution:

[0026] A width-adjustable conveyor rack for SMT equipment, comprising a conveyor rack 1, a placement mechanism 2, and a substrate 3;

[0027] The conveyor frame 1 is internally provided with placement mechanisms 2 distributed on the left and right. The outer side of the placement mechanism 2 on one side is fixedly connected to the conveyor frame 1, and the outer side of the placement mechanism 2 on the other side is slidably connected to the conveyor frame 1. A plurality of substrates 3 are arranged between the placement mechanisms 2.

[0028] The side of the conveying frame 1 is fixedly connected to a hydraulic rod 4, and the free end of the hydraulic rod 4 is fixedly connected to the placement mechanism 2;

[0029] The placement mechanism 2 includes a placement frame 201, an adjustment body 202, and a push plate 203. The outer side of the placement frame 201 on one side is fixedly connected to the conveying frame 1, and the outer side of the placement frame 201 on the other side is slidably connected to the conveying frame 1. The adjustment body 202 is fixedly connected to the interior of the placement frame 201, and the bottom of the adjustment body 202 is fixedly connected to the push plate 203. The inner side of the push plate 203 is rotatably connected to the central rotating shaft 205, and the outer side of the central rotating shaft 205 is rotatably connected to the cross-arranged rotating plates 204. The other ends of the rotating plates 204 are rotatably connected to the side rotating shafts 206.

[0030] A placement plate 207 is also fixedly connected to the outer side of the central rotating shaft 205 .

[0031] The central rotating shaft 205 at the bottom is rotatably connected to the placement rack 201 .

[0032] A sliding groove 208 is formed inside the placement rack 201 , and a plurality of central rotating shafts 205 are slidably connected inside the sliding groove 208 .

[0033] In actual use, the existing SMT conveyor rack has its plates placed inside the conveyor rack and distributed in an upper and lower manner. The plates are pushed to the equipment on one side by an external pushing mechanism, and then the conveyor rack is automatically lifted to facilitate the next plate to move up for stocking. However, in actual use, the PCB plates are of different sizes. One conveyor rack can only transport PCB plates of one specification, which has a limited scope of use. When in use, the placement mechanism 2 on one side is driven to move by activating the hydraulic rod 4 according to the size of the PCB plate. At this time, the distance between the placement mechanisms 2 on both sides can be controlled, thereby ensuring that PCB plates of different widths can be fixed, thereby expanding the scope of use of the conveyor rack 1. The rotating plate 204, the central rotating shaft 205 and the side rotating shaft 206 are used in combination to control the distance between the placement plates 207, which facilitates the control of the distance between the substrates 3 and ensures that the substrates 3 can be stably pushed to the next process.

[0034] In this embodiment, the sliding groove 208 can ensure the stable movement of the central rotating shaft 205 and prevent the frame composed of the rotating plate 204, the central rotating shaft 205 and the side rotating shafts 206 from tilting. Example 2

The end of the main shaft of the above-mentioned motor 2022 is fixedly connected to the threaded shaft 2023, and the outer side of the threaded shaft 2023 is spirally connected to a threaded sleeve 2024. The bottom of the above-mentioned threaded sleeve 2024 is fixedly connected to the push plate 203.

[0036] A groove is formed on the side of the threaded sleeve 2024 , and a limiting block 2025 is provided inside the groove. The outer side of the limiting block 2025 is fixedly connected to the fixing frame 2021 .

[0037] By starting the motor 2022 to rotate, the threaded shaft 2023 is driven to rotate. At this time, the threaded sleeve 2024 drives the push plate 203 to move, so that the central shaft 205 can slide inside the slide groove 208, which is used to control the distance between the central shafts 205, thereby ensuring the use range of the device;

[0038] In this embodiment, a groove is provided on the side of the threaded sleeve 2024, and a limit block 2025 is set in it to ensure that the threaded sleeve 2024 can move up and down stably under the rotation of the threaded shaft 2023, thereby being used to adjust the distance between the placement plates 207.
