After the pins of the plug terminals are inserted into the PCB board, in addition to subsequent soldering, screw connection is also required. The screws fix the PCB board and the plug terminals together to achieve a stable connection.

[0004] Normally, screw mounting holes are located on the back of the PCB board. Screws are rotated from the back of the PCB board to install them and securely connect to the plug terminals.

[0031] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1 As shown, the front side of the PCB board 3 is equipped with several plug terminals 31; as Figure 2 As shown, several screws 32 need to be installed on the back of the PCB board 3 to achieve a fixed connection between the PCB board 3 and the plug terminal 31.

[0033] Please refer to Figures 3 to 10 This utility model provides a vehicle rotation mechanism.

[0034] like Figure 3 and Figure 4 As shown, the vehicle rotation mechanism includes a placement plate 1 mounted on one side, a docking plate 4 mounted on the upper part, a first vertical drive assembly 6 mounted on the other side for driving the docking plate 4 to move vertically, and a rotation drive assembly 7 for driving the docking plate 4 to rotate.

[0035] like Figure 4 As shown, the placement plate 1 is used to place the carrier 2, and the carrier 2 is equipped with two PCB boards 3 arranged side by side; the PCB boards 3 are fixed inside the carrier 2, thereby facilitating the transportation of the PCB boards 3 and subsequent assembly.

[0036] A docking plate 4 is mounted above the placement plate 1. The docking plate 4 docks with the carrier 2 on which the PCB board 3 is mounted. Specifically, a first vertical drive assembly 6 is mounted on one side of the docking plate 4 and is connected to it for transmission. When the carrier 2 is placed on the placement plate 1, the first vertical drive assembly 6 drives the docking plate 4 to move downward, so that the docking plate 4 docks with the carrier 2. After the docking plate 4 contacts the carrier 2, clamping assemblies 5 are provided on both sides of the docking plate 4 to clamp the carrier 2. After the clamping assemblies 5 clamp the carrier 2, the first vertical drive assembly 6 drives the docking plate 4 and the carrier 2 to move vertically upward, so that the carrier 2 is detached from the placement plate 1, facilitating subsequent rotation. Figure 5As shown, the docking plate 4 is also connected to a rotary drive assembly 7, which drives the docking plate 4 and the carrier 2 clamped on the docking plate 4 to rotate 180°, turning the back of the PCB board 3 upwards to facilitate the installation of screws 32 on the back of the PCB board 3. After completing the above operation, the carrier 2 can be rotated back to its initial state and placed vertically back onto the placement plate 1. Through the above structural design, the carrier rotation mechanism provided by this utility model can efficiently and stably complete the carrier flipping operation, thereby improving the assembly efficiency of the PCB board 3, reducing the intensity of manual operation, and is suitable for various scenarios in automated production lines.

[0037] The above-described embodiments are suitable for situations where the carrier 2 is placed manually on the placement plate 1, or the carrier 2 is precisely placed on the placement plate 1 by an automated robotic arm.

[0038] If the carrier 2 and PCB board 3 are transported by chains or belts on both sides, then the carrier 2 and PCB board 3 need to be driven to detach from the chains or belts, thereby separating the carrier 2 from the chains or belts for subsequent flipping operations. For this purpose, a second vertical drive assembly 8 is provided below the placement plate 1. The second vertical drive assembly 8 is connected to the placement plate 1 and drives the placement plate 1, carrier 2, and PCB board 3 to move vertically upwards together, thereby causing the carrier 2 to detach from the support surface of the chain or belt.

[0039] Furthermore, while the second vertical drive assembly 8 drives the placement plate 1, the carrier 2, and the PCB board 3 to move upward, the first vertical drive assembly 6 drives the docking plate 4 to move vertically downward, so that the docking plate 4 and the carrier 2 are docked. At the same time, the clamping assembly 5 clamps the carrier 2, so that the carrier 2 is fixedly installed on the lower part of the docking plate 4.

[0040] like Figure 6 As shown, the carrier 2 includes a first plate 21, on which two placement grooves 22 are arranged side by side. The placement grooves 22 are used to place the PCB board 3. The first plate 21 is also marked with the conveying direction of the belt or chain.

[0041] like Figure 10 As shown, the placement groove 22 is also provided with several through grooves 23, which facilitate the subsequent screws 32 to pass through the through grooves 23 to perform the locking operation between the PCB board 3 and the plug terminal 31. The position of the through grooves 23 corresponds to the screw holes on the PCB board 3, thereby ensuring that the screws 32 can accurately pass through the carrier 2 and be locked onto the PCB board 3.

[0042] like Figure 7As shown, the placement groove 22 is also equipped with a plurality of first pins 24 for positioning the PCB board 3; the PCB board 3 is provided with positioning holes that cooperate with the first pins 24, and the PCB board 3 is precisely positioned by inserting the first pins 24 into the positioning holes.

[0043] The aforementioned first pin 24 can effectively position the PCB board 3, but it cannot completely fix the PCB board 3. Therefore, it is necessary to install several single-sided buckles 25 on the first board body 21. The single-sided buckles 25 are distributed along the edge of the placement groove 22 to press and fix the PCB board 3 inside the placement groove 22, thereby preventing the PCB board 3 from shifting or falling off during the flipping process.

[0044] Furthermore, such as Figure 7 As shown, the single-sided buckle 25 includes a rotating shaft 251 mounted on the first plate 21 and a pressing part 252 that rotates around the rotating shaft 251. In use, the pressing part 252 rotates around the rotating shaft 251, and one end of the pressing part 252 rotates to the top of the PCB board 3 to press and fix the PCB board 3.

[0045] Furthermore, such as Figure 7 As shown, a first limiting pin 253 is installed on one side of the pressing part 252, and a second limiting pin 254 is installed on the other side. The first limiting pin 253 and the second limiting pin 254 are both installed on the first plate 21 to limit the rotation angle of the pressing part 252. The first limiting pin 253 is used to limit the pressing part 252 to press the PCB board 3 into place, and the second limiting pin 254 is used to limit the pressing part 252 to leave the PCB board 3 into place.

[0046] like Figure 6 As shown, the first plate 21 is provided with a plurality of first pin holes 26, and the placement plate 1 is provided with a plurality of second pins 16 corresponding to the first pin holes 26. The second pins 16 are inserted into the first pin holes 26; thereby achieving precise positioning of the first plate 21 on the placement plate 1, and also achieving positioning and partial fixation of the carrier 2, leaving a vertical degree of freedom so that the carrier 2 can be vertically removed from the placement plate 1 in the future, which is convenient for subsequent rotation operations.

[0047] like Figure 4As shown, the second vertical drive assembly 8 includes a first vertical cylinder 81 installed at the bottom of the placement plate 1. The first vertical cylinder 81 drives the placement plate 1 and the carrier 2 to move vertically, so that the carrier 2 can be disengaged from the belt or chain. In order to make the vertical movement more stable, the second vertical drive assembly 8 also includes guide posts 82 installed around the bottom of the placement plate 1. The guide posts 82 are four evenly distributed at the four corners of the bottom of the placement plate 1. Each guide post 82 is fitted with a guide sleeve 83, which slides with the guide post 82. The guide sleeve 83 can be fitted with ball bearings or linear bearings inside to reduce movement resistance and improve guiding accuracy.

[0048] like Figure 10 As shown, the docking plate 4 is equipped with a plurality of docking plates 41 corresponding to the PCB board 3. Each docking plate 41 has a receiving groove 42; the receiving groove 42 is used to accommodate the protruding portion of the PCB board 3. In this embodiment, the protruding portion of the PCB board 3 is the upper part of the plug terminal 31. When the docking plate 4 descends to contact the carrier 2, the receiving groove 42 can tightly fit with the plug terminal 31, thereby protecting and limiting the PCB board 3 and preventing it from shifting or being damaged during the docking process. Furthermore, the docking plate 41 is made of black acetal alloy, an engineering plastic with good wear resistance.

[0049] To achieve precise docking with the PCB board 3, the docking plate 4 is also equipped with several third pins 43. The third pins 43 adopt a stepped structure design, which can not only accurately position the PCB board 3, but also limit the vertical direction, so that the PCB board 3 and the docking plate 4 have a suitable vertical distance. Correspondingly, the first plate body 21 is provided with several second pin holes 27 corresponding to the third pins 43. During docking, the third pins 43 are inserted into the second pin holes 27, thereby achieving precise positioning between the docking plate 4 and the carrier 2.

[0050] Furthermore, the lower end of the third pin 43 is provided with a guide slope so as to guide the third pin 43 smoothly into the second pin hole 27 during the docking process.

[0051] like Figure 8 As shown, there are two clamping components 5, which are respectively installed on both sides of the docking plate 4. In other embodiments, there may be multiple clamping components 5 according to actual needs.

[0052] Furthermore, the clamping assembly 5 includes a clamping cylinder 51 mounted on the docking plate 4. The output end of the clamping cylinder 51 is connected to a clamping block 52. The clamping block 52 is provided with a clamping groove 53. The clamping groove 53 is used to clamp the edge portion of the carrier 2. The clamping cylinder 51 drives the clamping block 52 to approach the edge of the carrier 2, so that the clamping groove 53 is in close contact with the carrier 2 and applies a clamping force inward, thereby firmly fixing the carrier 2 on the docking plate 4.

[0053] Furthermore, such as Figure 9 As shown, the clamping groove 53 has guide ramps 54 on both sides. The guide ramps 54 are used to guide the edge portion of the carrier 2 into the clamping groove 53, making the clamping process smoother and avoiding clamping failure or damage to the carrier 2 due to edge misalignment. During the operation of the clamping assembly 5, the guide ramps 54 can effectively reduce the frictional resistance between the edge of the carrier 2 and the clamping groove 53, improving clamping efficiency and stability.

[0054] like Figure 5 As shown, the rotary drive assembly 7 includes a frame 71 mounted around the docking plate 4, the docking plate 4 rotating inside the frame 71; a rotary motor 72 is mounted on one side of the frame 71, and a first rotary shaft 73 is mounted at the end of the rotary motor 72. The first rotary shaft 73 passes through the frame 71 and is connected to the docking plate 4 in a transmission manner. The frame 71 does not rotate and only serves as a support structure for the rotary motor 72 and the first rotary shaft 73.

[0055] To ensure more stable rotation, extend service life, and facilitate subsequent installation of screws 32, a second rotating shaft 74 is also installed inside the frame 71. The second rotating shaft 74 is connected to the docking plate 4 and is coaxially arranged with the first rotating shaft 73. The docking plate 4 rotates inside the frame 71 via the first rotating shaft 73 and the second rotating shaft 74. Furthermore, the docking plate 4 is installed between the first rotating shaft 73 and the second rotating shaft 74, which ensures uniform rotational force. Simultaneously, during subsequent installation of screws 32, the first rotating shaft 73, the second rotating shaft 74, and the frame 71 can effectively distribute the force on the carrier 2 during rotation.

[0056] like Figure 3As shown, a vertical plate 75 is also installed at the lower part of the frame 71 and the rotary motor 72. The frame 71 is installed on one side of the vertical plate 75, and the rotary motor 72 is installed on the other side of the vertical plate 75. The frame 71 and the rotary motor 72 are both installed on the upper part of the vertical plate 75. A first vertical drive assembly 6 is installed on one side of the vertical plate 75 and is connected to it in a transmission manner. The first vertical drive assembly 6 is used to drive the vertical plate 75 to move in the vertical direction, thereby driving the frame 71, the rotary motor 72 and the docking plate 4 to move up and down as a whole.

[0057] like Figure 3 As shown, the first vertical drive assembly 6 includes a support frame 61 mounted on one side of the vertical plate 75. The support frame 61 is fixed on the frame and is a stationary component. A second vertical cylinder 62 is mounted on the lower part of the support frame 61. The output end of the second vertical cylinder 62 is connected to the vertical plate 75. The extension and retraction of the second vertical cylinder 62 drives the vertical plate 75 to move up and down in the vertical direction, thereby realizing the overall lifting function of the docking plate 4 and its carrier 2.

[0058] To further improve the stability of the docking plate 4 during the lifting process, the support frame 61 is equipped with two parallel vertical guide rails 63. A vertical slider 64 is slidably connected to each vertical guide rail 63, and the vertical slider 64 is fixedly connected to the vertical plate 75. The second vertical cylinder 62 drives the vertical plate 75 to slide vertically along the vertical guide rails 63 via the vertical slider 64. The cooperative design of the vertical guide rails 63 and the vertical slider 64 effectively improves the guiding accuracy of the docking plate 4 during the lifting process, while reducing swaying and frictional resistance during movement.

[0059] Furthermore, both ends of the vertical guide rail 63 are equipped with buffer components to absorb the impact force that may be generated during the lifting process, thereby further improving the overall stability of operation.

[0060] Furthermore, in order to keep the placement plate 1, carrier 2, PCB board 3 and mating plate 4 stable during the installation of screw 32, a first limiting component is installed at the lower part of the guide post 82, and a second limiting component is installed at the lower part of the vertical slider 64. The first and second limiting components support and limit the guide post 82 and the vertical slider 64 in the vertical direction, so that the guide post 82 and the vertical slider 64 will not be vertically displaced due to force when the screw 32 is installed, thereby ensuring the installation accuracy and stability of screw 32.

[0061] In this embodiment, four first limiting components are provided, corresponding to four guide posts 82; two second limiting components are provided, corresponding to the vertical sliders 64 on both sides.

[0062] like Figure 4 As shown, the first limiting assembly includes a first limiting cylinder 84 mounted on the lower part of the guide post 82 and a first limiting block 85 connected to the output end of the first limiting cylinder 84. The first limiting cylinder 84 is mounted on the frame for fixation. After the guide post 82 moves vertically to the top, the first limiting cylinder 84 drives the first limiting block 85 to extend and be mounted on the lower part of the guide post 82 to vertically limit and fix the guide post 82. After the screws 32 are installed, the first limiting cylinder 84 drives the first limiting block 85 to retract, releasing the limitation on the guide post 82.

[0063] Similarly, such as Figure 3 As shown, the limiting principle of the second limiting component is the same as that of the first limiting component. The second limiting component includes a second limiting cylinder 86 mounted on the vertical plate 75 and a second limiting block 87 connected to the output end of the second limiting cylinder 86. After the vertical slider 64 moves to the designated position, generally after the docking plate 4 and the carrier 2 are rotated and placed on the placement plate 1, and the screw 32 installation is about to begin, the second limiting cylinder 86 drives the second limiting block 87 to extend, limiting and fixing the vertical slider 64 to ensure that it does not move vertically during installation. After the screw 32 is installed, the second limiting cylinder 86 drives the second limiting block 87 to retract, releasing the limiting operation.

[0064] The operating steps of the vehicle's in-situ rotation mechanism are as follows:

[0065] Step S1: The chain or belt transports the carrier 2 and the PCB board 3 inside the carrier 2 to the designated position, which is above the placement plate 1 and below the docking plate 4;

[0066] Step S2: The first vertical cylinder 81 drives the placement plate 1 to move vertically upward. During the vertical upward movement, the second pin 16 is inserted into the first pin hole 26; the carrier 2 is mounted on the placement plate 1, and at the same time, during the vertical upward movement, the carrier 2 is disengaged from the chain or belt.

[0067] Step S3: After the placement plate 1, carrier 2, and PCB board 3 are vertically positioned, the second vertical cylinder 62 drives the docking plate 4 to move vertically downward, wherein the third pin 43 is inserted into the second pin hole 27; thereby achieving precise positioning between the docking plate 4 and the carrier 2; the clamping cylinder 51 drives the clamping block 52 to approach the edge of the carrier 2, so that the clamping groove 53 is in close contact with the carrier 2 and applies clamping force inward, thereby firmly fixing the carrier 2 on the docking plate 4;

[0068] Step S4: After the clamping assembly 5 clamps the carrier 2 into place, the second vertical cylinder 62 drives the docking plate 4 to move vertically upward away from the placement plate 1, thereby obtaining space for subsequent rotation.

[0069] Step S5: After the docking plate 4 is vertically in place and has room to rotate, the rotary motor 72 drives the docking plate 4 to rotate 180° inside the frame 71, so that the bottom of the PCB board 3 faces upward, allowing the subsequent installation of screws 32 to proceed.

[0070] Step S6: The second vertical cylinder 62 drives the docking plate 4 to move vertically downward and close to the placement plate 1, placing the rotated docking plate 4, PCB board 3 and carrier 2 on the placement plate 1. The rotated docking plate 4 is also provided with pin holes corresponding to the second pin 16, so that the docking plate 4, PCB board 3 and carrier 2 can be placed flat on the placement plate 1.

[0071] Step S7: Prepare for screw 32 installation. The first limiting cylinder 84 drives the first limiting block 85 to extend and be installed at the lower part of the guide post 82 to vertically limit and fix the guide post 82; the second limiting cylinder 86 drives the second limiting block 87 to extend and limit and fix the vertical slider 64.

[0072] Step S8: Install multiple screws 32, which pass through the through groove 23 to lock the PCB board 3 and the plug terminal 31.

[0073] Step S9: After screw 32 is installed, the first limiting cylinder 84 drives the first limiting block 85 to retract, and the second limiting cylinder 86 drives the second limiting block 87 to retract.

[0074] Step S10: The second vertical cylinder 62 drives the docking plate 4 to move vertically upward, away from the placement plate 1, thereby obtaining space for subsequent rotation; the rotary motor 72 drives the docking plate 4 to rotate 180° inside the frame 71; so that the bottom of the PCB board 3 faces downward;

[0075] Step S11: The second vertical cylinder 62 drives the docking plate 4 to move vertically downward, placing the PCB board 3 with the screws 32 installed on the placement plate 1; the first vertical cylinder 81 drives the placement plate 1 to move vertically downward, and the carrier 2 returns to the chain or belt, and the carrier 2 is used for conveying and proceeding to the next process.
