Description

Technical Field

[0001] The utility model belongs to the technical field of PCB board processing, in particular to a board turning machine for PCB board processing. Background Art

[0002] PCBs, also known as printed circuit boards, provide electrical connections for electronic components. They are often referred to as "PCB" rather than "PCB board." PCB design primarily involves layout design. The primary advantage of using PCBs is that they significantly reduce wiring and assembly errors, improving automation and productivity. PCBs can be categorized by the number of layers, including single-sided, double-sided, four-layer, six-layer, and other multi-layer boards. Because PCBs are not typically end products, the terminology is somewhat confusing. For example, the motherboard used in personal computers is called a mainboard, not a circuit board. While a mainboard contains a circuit board, they are not the same. Therefore, when evaluating the industry, the two are related but not identical. Another example: because integrated circuit components are mounted on a PCB, the news media often refer to it as an IC board. However, this is not the same as a PCB. The PCB we typically refer to is a bare board—that is, a PCB without components.

[0003] During the PCB processing, when one side is produced and the other side is produced, it is often necessary to manually turn the circuit board over, which wastes human resources, increases the production cost of the product, and cannot adapt to automated production. Utility Model Content

[0015] The placement slots are opened on the flip plate. There are four placement slots in total, which are evenly spaced along the circumferential direction and are used to support and limit the PCB board.

[0016] In the above technical solution, further, a support mechanism for supporting the PCB board is provided on the right side of the chassis, and the support mechanism includes:

[0017] Fixed plates are provided at both ends of the right side of the top of the chassis;

[0018] The support platform is arranged between the tops of the two fixed plates on the same side. The two support platforms are symmetrically distributed, and the support platform is located on the right side of the flip plate.

[0019] In any of the above technical solutions, further, a pushing mechanism for pushing the PCB board into the placement groove of the flip plate is provided at the bottom of the support platform, and the pushing mechanism includes:

[0020] A bracket is arranged at the bottom of the support platform;

[0021] Cylinder 1, arranged on the bracket;

[0026] A support plate is provided between the top left sides of the two base frames;

[0027] A mounting plate is arranged around the top of the support plate;

[0028] The transmission shaft is rotatably arranged between the two mounting plates on the same side;

[0029] a pulley, arranged on the transmission shaft;

[0030] The conveyor belt is placed between two pulleys, and the pulley is located on the left side of the turning plate;

[0031] Motor 2 is arranged on one of the mounting plates, and an output shaft of motor 2 is connected to the transmission shaft.

[0032] In any of the above technical solutions, further, a stabilizing mechanism is included, and the stabilizing mechanism includes:

[0033] Cylinder 2, arranged on the front and rear sides of the support plate;

[0034] A support frame is provided on the second piston rod of the cylinder;

[0035] The support plate is set on the mounting frame and is located on the inner wall of the conveyor belt. It is used to support the PCB board on the conveyor belt to prevent the conveyor belt from collapsing due to the weight of the PCB board.

[0039] The beneficial effects of the utility model are:

[0040] 1. The placement slot supports and limits the position of the PCB. The rotational power of Motor 1 drives the flip plate through the output shaft, flipping the PCB to the left side of the flip plate. The PCB changes sides during rotation, thus flipping the completed PCB to the other side. By precisely controlling the rotation angle and speed of Motor 1, the PCB can be flipped quickly and accurately, allowing the board surface to be processed in different directions during the processing process.

[0041] 2. The support table provides additional support points to ensure that the PCB board is fully supported before flipping, so that the board surface of the PCB board can be processed. After the processing is completed, the PCB board can be turned over to process the other side of the PCB board;

[0042] 3. The push plate moves to the left through the extension and retraction of the piston rod of the cylinder. The anti-slip beads on the push plate increase the friction with the PCB, ensuring that the PCB stably enters the placement slot of the flip plate during the pushing process. Under the rotation operation of the flip plate, the PCB is turned over, thus effectively controlling and pushing the PCB, ensuring that it is accurately placed and positioned in the placement position of the flip plate;

[0043] 4. Turn the PCB board over by the flip plate, and under the action of the conveyor belt, transport the PCB board to the appropriate position where it needs to be processed, ensuring that the PCB board is ready for processing. In this way, the flipped PCB board is effectively transported to the position where its board surface needs to be processed for subsequent processing;

[0044] 5. Cylinder 2 adjusts the expansion and contraction of the piston rod by controlling the air pressure or hydraulic pressure, thereby adjusting the height of the support plate to ensure that the support plate maintains appropriate contact force with the conveyor belt, effectively supporting the PCB board and preventing the conveyor belt from deformation or damage. It ensures that the PCB board on the conveyor belt is always in a stable state, so that the conveyor belt can accurately and efficiently complete the PCB board processing task.

DETAILED DESCRIPTION

[0052] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0053] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, technologies, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0054] Example 1:

[0055] like Figure 1-Figure 3 As shown, this embodiment provides a PCB board processing turnover machine, comprising:

[0056] There are two chassis 1, symmetrically distributed;

[0057] The turning mechanism 2 is provided on the base frame 1 and is used for automatically turning over the PCB board;

[0058] The turning mechanism 2 includes:

[0059] The mounting frame 21 is provided in the middle of the top of the base frame 1 by means of bolt connection;

[0060] The rotating shaft 22 is rotatably disposed between the two mounting frames 21;

[0061] The frame 23 is provided on the front chassis 1;

[0062] Motor 1 24 is provided on the frame 23, and the output shaft of motor 1 24 is connected to the rotating shaft 22;

[0063] Bushings 25 are provided at the front and rear ends of the rotating shaft 22;

[0064] The turning plate 26 is provided on the shaft sleeve 25;

[0065] The placement slots 27 are provided on the flip plate 26 . There are four placement slots 27 , which are evenly spaced along the circumferential direction and are used to support and restrict the PCB.

[0066] In this technical solution, the flip machine includes two symmetrically distributed base frames 1, which constitute the basic structure of the entire machine and provide support and stability. The mounting frame 21 is connected to the top middle position of the base frame 1 by bolts, serving as the support frame of the flip mechanism 2. The rotating shaft 22 is arranged between the two mounting frames 21, allowing rotation on it. This rotating shaft 22 is the core component of the flip mechanism 2 and is used to support and transmit rotational power. The frame 23 is installed on the front side of the base frame 1 to provide additional support structure and fix the position of the motor. Motor 1 24 is installed on the frame 23, and its output shaft is connected to the rotating shaft 22. The function of motor 1 24 is to provide rotational power and drive the rotating shaft 22 to perform a flipping action. The shaft sleeve 25 is arranged at the front and rear ends of the rotating shaft 22 to maintain the stability and axial position of the rotating shaft 22. The flip plate 26 is directly arranged on the shaft sleeve 25 and rotates with the rotating shaft 22. The design of the flip plate 26 takes into account the support and fixation requirements of the PCB board. Four placement slots 27 are provided on the flip plate 26. These placement slots 27 are evenly spaced along the circumferential direction. Their main function is to support and limit the position of the PCB board, ensuring that the PCB board remains stable and in the correct position during the flipping process.

[0067] Working principle overview:

[0068] When a PCB needs to be flipped, the operator first places the PCB in the placement slot 27 on the right side of the flip plate 26. The placement slot 27 supports and limits the position of the PCB, ensuring that the PCB remains stable and in the correct position during the flipping process. The operator can then proceed with processing the PCB. When one side of the PCB is finished and the other side is ready, the operator or the automatic control system starts the motor 24. The rotational power of the motor 24 is transmitted to the rotating shaft 22 through the output shaft, causing the rotating shaft 22 and the connected flip plate 26 to rotate together. The placement slot 27 on the flip plate 26 maintains the stability of the PCB, causing it to flip to the left side of the flip plate 26, while allowing the PCB to change position during rotation, thereby flipping the completed PCB surface to the other side. At this point, the operator can process the unprocessed surface. By precisely controlling the rotation angle and speed of the motor 24, the PCB can be quickly and accurately flipped, allowing the board surface to be processed in different directions during processing. This achieves automatic flipping of the PCB, providing an efficient and accurate solution for multi-side processing during processing.

[0069] Example 2:

[0070] This embodiment provides a PCB board processing turnover machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0071] like Figure 1 、 Figure 4 and Figure 5As shown, in this embodiment, the bottom frame 1 is optimized and provided with a support mechanism 3 for supporting the PCB board on the right side. The support mechanism 3 includes:

[0072] The fixing plates 31 are provided at both ends of the top right side of the chassis 1;

[0073] The support platform 32 is disposed between the tops of the two fixed plates 31 on the same side. The two support platforms 32 are symmetrically distributed, and the support platform 32 is located on the right side of the flip plate 26 .

[0074] In this technical solution, fixed plates 31 are provided at both ends of the top right side of the base frame 1. The function of the fixed plates 31 is to provide a stable support structure to ensure the fixed position of the PCB board during the flipping process. The support platform 32 is arranged between the tops of the two fixed plates 31 on the same side and is symmetrically distributed. They are located on the right side of the flip plate 26. The main function of the support platform 32 is to provide additional support and stability for the PCB board, so as to facilitate the operator to process the PCB board surface and ensure that the PCB board does not move or tilt during the flipping process.

[0075] like Figure 1 、 Figure 4 and Figure 5 As shown, in this embodiment, the support platform 32 is optimized and provided with a pushing mechanism 4 at the bottom thereof for pushing the PCB board into the placement groove 27 of the flip plate 26. The pushing mechanism 4 includes:

[0076] The bracket 41 is provided at the bottom of the support platform 32;

[0077] Cylinder 1 42, mounted on bracket 41;

[0078] A connecting plate 43 is provided between the piston rods of the two cylinders 42;

[0079] A push plate 44 is provided on the connecting plate 43 and is located between the two support platforms 32;

[0080] There are a plurality of anti-slip beads 45 evenly spaced on the top of the push plate 44 .

[0081] In this technical solution, the bracket 41 is located at the bottom of the support platform 32, providing support and a fixed position for the installation and support of subsequent components. Cylinder 1 42 is installed on the bracket 41, which is one of the key components of the pushing mechanism 4. Cylinder 1 42 drives the movement of the piston rod inside it through compressed air or hydraulic force. The connecting plate 43 is installed between the piston rods of the two cylinders 1 42, serving as one of the movable parts of cylinder 1 42. The push plate 44 is installed on the connecting plate 43 and is located between the two support platforms 32. The function of the push plate 44 is to move in a direction parallel to the support platform 32 under the action of cylinder 1 42, thereby pushing the PCB board into the placement groove 27 of the flip plate 26. Anti-slip beads 45 are evenly spaced on the top of the push plate 44. The purpose of designing these anti-slip beads 45 is to increase the friction between the push plate 44 and the PCB board to ensure that the PCB board does not slide or become unstable during the pushing process.

[0082] Working principle overview:

[0083] When it is necessary to use the flip machine for PCB board processing, the operator first places the PCB board on the support table 32, and then starts the cylinder 1 42. The compressed air or hydraulic force of the cylinder 1 42 pushes the piston rod. The movement of the piston rod drives the connecting plate 43 and the push plate 44 on the connecting plate 43 to move to the left together. The anti-slip beads 45 on the push plate 44 increase the friction with the PCB board, which can ensure that the PCB board stably enters the placement groove 27 of the flip plate 26 during the pushing process. Once the PCB board is pushed into the placement groove 27, the cylinder 1 42 stops moving, the push plate 44 remains in the required position, and the tail of the PCB board is located on the support table 32. At this time, the board surface of the PCB board can be processed. When the PCB board processing is completed, the PCB board is ready for flipping and processing. The motor is started, and the power of the motor is transmitted to the connected flip plate 26 through the rotating shaft 22, and the PCB board begins to be flipped from one side to the other. The support platform 32 is located on the right side of the flip plate 26, providing an additional support point to ensure that the right side of the PCB board is fully supported during the flipping process. After the PCB board is flipped, the other side of the PCB board can be processed. In this way, the support mechanism 3 effectively cooperates with the flip mechanism 2 to ensure the stability and accuracy of the PCB board during the processing process, so that the processing and flipping operations can be completed accurately, thereby improving production efficiency and product quality. At the same time, the PCB board is effectively controlled and pushed to ensure that it accurately enters and is positioned at the placement position of the flip plate 26, providing a stable and reliable foundation for subsequent processing steps.

[0084] Example 3:

[0085] This embodiment provides a PCB board processing turnover machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0086] like Figure 1 and Figure 6 As shown, in this embodiment, the bottom frame 1 is optimized to have a feeding mechanism 5 for conveying PCB boards on the top left side. The feeding mechanism 5 includes:

[0087] The support plate 51 is provided between the top left sides of the two bottom frames 1;

[0088] The mounting plate 52 is arranged around the top of the support plate 51;

[0089] The transmission shaft 53 is rotatably arranged between the two mounting plates 52 on the same side;

[0090] A pulley 54 is provided on the transmission shaft 53;

[0091] The conveyor belt 55 is sleeved between two pulleys 54, and the pulley 54 is located on the left side of the flip plate 26;

[0092] The second motor 56 is mounted on one of the mounting plates 52 , and the output shaft of the second motor 56 is connected to the transmission shaft.

[0093] In this technical solution, when the flip plate 26 flips the PCB board from one surface to the other, the PCB board is located on the conveyor belt 55. At this time, the motor 2 56 is started, and the motor 2 56 drives the transmission shaft 53 to rotate, causing the pulley 54 installed thereon to rotate. The rotation of the pulley 54 drives the conveyor belt 55 to move together. The conveyor belt 55 provides sufficient friction on its surface to stably carry the PCB board for transportation. Once the PCB board is transported to the appropriate position where processing is required, the motor 2 56 is turned off and the conveyor belt 55 remains stationary, ensuring that the PCB board is ready for processing. In this way, the flipped PCB board is effectively transported to the position where its board surface needs to be processed for subsequent processing, ensuring stable transportation and precise positioning of the PCB board, thereby improving processing efficiency and product quality.

[0094] Example 4:

[0095] This embodiment provides a PCB board processing turnover machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0096] like Figure 1 and Figure 6 As shown, in this embodiment, the optimization further includes a stabilizing mechanism 6, which includes:

[0097] Cylinder 2 61, provided on both sides of the front and rear of the support plate 51;

[0098] Support frame 62, provided on the piston rod of cylinder 2 61;

[0099] The support plate 63 is provided on the mounting frame 21 and is located on the inner wall of the conveyor belt 55 for supporting the PCB boards on the conveyor belt 55 to prevent the conveyor belt 55 from collapsing due to the weight of the PCB boards.

[0100] In the present technical solution, when the PCB board is flipped to the left side of the flip plate 26, the PCB board is located on the conveyor belt 55. In order to prevent the conveyor belt 55 from collapsing or deforming due to the weight of the PCB board, its support plate 63 is adjusted as needed by the cylinder 2 61 so that the support plate 63 can correctly support the PCB board on the conveyor belt 55 and prevent the conveyor belt 55 from deforming, so that the conveyor belt 55 can convey the PCB board more stably. The cylinder 2 61 adjusts the extension and contraction of the piston rod by controlling the air pressure or hydraulic pressure, thereby adjusting the height of the support plate 63. This ensures that the support plate 63 maintains appropriate contact force with the conveyor belt 55, effectively supports the PCB board and prevents it from deforming or damaging. In this way, the position of the support plate 63 is continuously monitored and adjusted to ensure that the PCB board on the conveyor belt 55 is always in a stable state, so that the conveyor belt 55 can accurately and efficiently complete the PCB board processing task.

[0101] like Figure 1 and Figure 6 As shown, in this embodiment, the optimization further includes a rotating mechanism 7, which includes:

[0102] Motor 3 71, arranged on the left side of the chassis 1;

[0103] Gear 72 is provided on the output shaft of motor three 71 and outside of cylinder two 61 , and the two gears 72 are meshed with each other.

[0104] In the present technical solution, when it is necessary to inspect and repair the conveyor belt 55, the second cylinder 61 is started, and the piston rod of the second cylinder 61 is extended and retracted to adjust the height of the support plate 63. When the support plate 63 is adjusted to not in contact with the conveyor belt 55, the second cylinder 61 is closed, and then the third motor 71 is started. The third motor 71 drives the gear 72 to rotate, and the two gears 72 are engaged, so that the gear 72 drives the second cylinder 61 to rotate. The second cylinder 61 drives the support frame 62 to rotate through the piston rod, and the support frame 62 drives the support plate 63 to rotate. The support plate 63 rotates to the outside of the conveyor belt 55. At this time, the third motor 71 is closed, and the operator can inspect and repair the conveyor belt 55. Operation, when the maintenance operation is completed, start motor three 71, motor three 71 drives gear 72 to rotate, gear 72 drives cylinder two 61 to rotate, cylinder two 61 drives support plate 63 to rotate to the inside of conveyor belt 55 through support frame 62, turn off motor three 71, and start cylinder two 61, cylinder two 61 piston rod retracts and retracts, adjusts the height of support plate 63, makes support plate 63 contact with the inner wall of conveyor belt 55, support plate 63 provides support for conveyor belt 55, prevents conveyor belt 55 from being deformed due to the weight of PCB board, finally, turn off cylinder two 61, so that the position of support plate 63 can be adjusted to facilitate maintenance of conveyor belt 55.
