[0007] base plate;

[0008] Support plates are arranged on both sides of the top of the base plate;

[0049] 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.

[0050] 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.

[0051] Example 1:

[0052] like Figure 1-Figure 3 As shown, this embodiment provides a board separator for PCB board processing, including:

[0053] Base plate 1;

[0054] Support plates 2 are arranged on both sides of the top of the base plate 1;

[0055] The guide plate 3 is provided on the opposite surfaces of the two support plates 2;

[0056] The support shell 4 is slidably disposed between the two guide plates 3. There are two support shells 4, which are linearly distributed on both sides of the guide plates 3.

[0057] The cutting boss 5 is provided on the top of the supporting shell 4;

[0058] A board separation mechanism 7 is provided on the bottom plate 1 and is used for cutting the PCB board;

[0059] A dust collecting mechanism 6 is provided inside the supporting shell 4 and is used to remove debris and dust generated during the cutting process;

[0060] The dust collection mechanism 6 includes:

[0061] There are four shells 61, which are symmetrically arranged around the inner periphery of the supporting shell 4;

[0062] A vacuum cleaner 62 is disposed in the middle of the housing 61;

[0063] A dust suction groove 63 is formed between the dust collector 62 and the housing 61;

[0064] The dustproof net 64 is provided on the upper end surface of the dust suction groove 63 .

[0065] In the present technical solution, the support plates 2 are located on both sides of the top of the base plate 1, providing stability and support for the overall structure. The guide plates 3 are arranged on the opposite sides of the support plates 2 to ensure that the PCB board maintains the correct position and direction during the board separation process. The board separation mechanism 7 is located on the base plate 1 and is used for the actual PCB board cutting operation. The support shell 4 is slidably set between the guide plates 3, and a cutting boss 5 is provided on the top of the support shell 4. The cutting boss 5 is used to guide the cutting tool or to fix the PCB board to ensure the accuracy and stability of the cutting. The dust collection mechanism 6 is located inside the support shell 4, and its design is intended to remove debris and dust generated during the cutting process to keep the working environment clean and the operation efficient. It includes four shells 61, which are symmetrically arranged around the supporting shell 4. A dust collector 62 is provided inside each shell 61. A dust suction groove 63 is located between the dust collector 62 and the shell 61 to effectively collect and store debris and dust generated by cutting. A dustproof net 64 is provided on the upper end surface of the dust suction groove 63 to prevent the collected debris and dust from sticking to the surface of the PCB board, while allowing the flow of air and dust, ensuring the effective operation and long-term use of the dust suction mechanism 6.

[0066] Workflow:

[0067] When the board splitter is started, the PCB board is placed and stabilized on the cutting boss 5, and the board splitting mechanism 7 starts to operate. According to the set cutting boss 5 and the board splitting mechanism 7, a precise cutting operation is performed to separate the PCB board. During the cutting process, the PCB board is prone to generate debris, which can easily affect the quality of the PCB board and the cleanliness of subsequent processing. Therefore, the dust suction mechanism 6 collects and processes the debris and dust generated during the cutting process to ensure a clean working environment and stable cutting quality. When the board splitter 7 is cutting the PCB board, the debris generated by the PCB board cutting falls onto the dustproof net 64. At this time, the vacuum cleaner 62 is started and generates a strong suction force. The suction force is distributed in the dust suction groove 63, thereby sucking the debris and dust on the dustproof net 64, and the dust eventually enters the dust suction groove 63. After the operation is completed, the vacuum cleaner 62 is turned off. In this way, the PCB board cutting task can be completed efficiently and accurately, while keeping the operating environment clean and safe, and the debris and dust generated during the cutting process are processed to improve the cutting quality of the PCB board.

[0068] Example 2:

[0069] This embodiment provides a board separator for PCB board processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0070] like Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, the optimized plate separation mechanism 7 includes:

[0071] The mounting plates 71 are provided at the left and right ends of the front and rear sides of the top of the base plate 1;

[0072] The hydraulic cylinder 72 is provided on the mounting plate 71;

[0073] A connecting plate 73 is provided between the piston rods of the two hydraulic cylinders 72 on the same side;

[0074] The cutter 74 is disposed between the two connecting plates 73 and is located above the cutting boss 5 .

[0075] The PCB board is cut into two pieces by the cutter 74, and the cutter 74 is moved downwards to move the cutter 74. The cutter 74 is supported and guided by the cutter 74 to cut the PCB board. The design and position of the cutter 74 enable it to accurately cut the PCB board and complete the predetermined cutting task. The presence of the cutting boss 5 can help position and fix the PCB board to ensure the accuracy and stability of the cutting. The hydraulic system can accurately adjust the downward pressure and speed of the cutter 74 by controlling the action of the hydraulic cylinder 72 to meet the cutting requirements of PCB boards of different types and thicknesses. This design can ensure the safety and controllability of the operation during the cutting process, while improving production efficiency and cutting quality. The PCB board separator can effectively and accurately complete the cutting task of the PCB board, and is suitable for the efficient processing requirements of PCB boards in industrial production.

[0076] Example 3:

[0077] This embodiment provides a PCB board separator, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0078] like Figure 1 and Figure 2 As shown, in this embodiment, it is optimized that a limit frame 8 for limiting the position of the PCB board is provided on the upper side of the support shell 4.

[0079] In the present technical solution, when preparing to separate the PCB board, the operator places the PCB board in the support shell 4 and ensures that the PCB board is properly aligned with the limit frame 8. The design of the limit frame 8 enables it to limit the position of the board during the placement of the PCB board to prevent it from moving or offsetting during the separation process. After the separation machine is started, the hydraulic system or other cutting mechanism begins to perform the cutting operation. At this time, the design of the support shell 4 and the limit frame 8 ensures that the PCB board always remains in the predetermined position and direction. During the cutting process, the limit frame 8 effectively prevents errors or instability factors of the PCB board, thereby ensuring the accuracy and consistency of the separation. The presence of the limit frame 8 improves the operating accuracy and safety of the PCB board separation machine, and reduces the errors caused by changes in the position of the PCB board. This can ensure that the position control of the PCB board is effectively implemented during the entire separation process, thereby improving production efficiency and ensuring product quality.

[0080] Example 4:

[0081] This embodiment provides a board separator for PCB board processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0082] like Figure 1 and Figure 2 As shown, in this embodiment, the optimized collecting mechanism 9 is provided outside the limiting frame 8, and the collecting mechanism 9 includes:

[0083] The plate outlet slots 91 are provided on the left and right sides and the front and rear ends of the limit frame 8. The plate outlet slots 91 extend obliquely from the inside to the outside and pass through the limit frame 8.

[0084] The collecting frame 92 is arranged around the outer side of the supporting shell 4 , and the collecting frame 92 is located at the plate outlet end of the plate outlet slot 91 .

[0085] like Figure 2 and Figure 3 As shown, in this embodiment, the cutting boss 5 is optimized and has inclined surfaces on the outer sides thereof that cooperate with the board outlet groove 91 so as to allow the PCB board scraps produced by cutting to slide out.

[0086] In this technical solution, board outlet slots 91 are provided on the outside of the retaining frame 8, including the left and right sides and the front and back ends. These outlet slots 91 extend obliquely inside and ultimately penetrate the entire retaining frame 8. They are arranged around the outer periphery of the support frame, at the board outlet end of the outlet slots 91. The function of the collection frame 92 is to receive the PCBs or other materials flowing out of the outlet slots 91.

[0087] Working process: When the PCB board separator is started, the hydraulic system will perform the board separation operation. The outer sides of the cutting boss 5 are designed with inclined surfaces. These inclined surfaces cooperate with the inclined angle inside the board outlet groove 91, so that the separated PCB boards or other materials can slide smoothly to the board outlet groove 91. The PCB board scraps produced by cutting will slide along the inclined surfaces around the cutting boss 5 and enter the board outlet groove 91. The internal inclined design of the board outlet groove 91 helps the scraps to flow smoothly to the collection frame 92 to avoid accumulation or obstruction of operation during the board separation process. This design can effectively collect the cut PCB boards and scraps quickly and accurately, which not only improves production efficiency, but also reduces material waste. The PCB board separator can effectively handle the scraps produced by cutting while completing the board separation operation efficiently and accurately, thereby improving production efficiency and material utilization.

[0088] Example 5:

[0089] This embodiment provides a board separator for PCB board processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0090] like Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, the optimization further includes a moving mechanism 10, and the moving mechanism 10 includes:

[0091] Racks 101 are provided between the two support shells 4. There are two racks 101 in total and they are symmetrically distributed.

[0092] A fixed plate 102 is disposed between the two racks 101;

[0093] Ear plates 103 are provided on the front and rear sides of the top of the bottom plate 1;

[0094] The transmission shaft 104 is rotatably disposed between the two ear plates 103, and the transmission shaft 104 passes through and extends out of the front support plate 2;

[0095] Gears 105 are provided at the front and rear ends of the transmission shaft 104, and the two gears 105 are meshed with the rack 101;

[0096] The frame 106 is provided on the top front side of the base plate 1;

[0097] The motor 107 is disposed on the frame 106 , and the output shaft of the motor 107 is connected to the transmission shaft 104 .

[0098] In the present technical solution, during operation, the cutter 74 performs a cutting operation on the PCB board, so that the PCB board is smoothly separated. When the PCB board in the support shell 4 below the cutter 74 is separated, the motor 107 is started, and the motor 107 drives the transmission shaft 104 to rotate, and the transmission shaft 104 drives the gear 105 to rotate. The gear 105 engages with the rack 101, so that the rack 101 drives the two support shells 4 to move to the left along the guide plate 3. When the separated support shell 4 moves out of the cutter 74, the motor 107 is turned off. At this time, the user can take out the separated PCB board in the support shell 4 and place the PCB board to be cut in the support shell 4. At the same time, the other support shell 4 moves to the bottom of the cutter 74, and the cutter 74 continues to cut. When the PCB board in the other supporting shell 4 is separated, the motor 107 is started, and the motor 107 drives the transmission shaft 104 to rotate in the opposite direction. The transmission shaft 104 drives the gear 105 to rotate in the opposite direction. The gear 105 engages with the rack 101, so that the rack 101 drives the supporting shell 4 to move to the right along the guide plate 3. At this time, the supporting shell 4 with the separated boards moves out of the cutter 74, and the supporting shell 4 that needs to be separated moves under the cutter 74. This cyclic operation can continuously cut the PCB boards to improve the separation effect, facilitate the user to take out the cut PCB boards, and place the PCB boards that need to be cut.

[0099] Example 6:

[0100] This embodiment provides a board separator for PCB board processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0101] like Figure 1 As shown, in this embodiment, it is optimized that a housing 11 is provided on the top of the base plate 1, and the housing 11 encloses the board separation mechanism 7 and the PCB board to be cut.

[0102] In this technical solution, the casing 11 is located on the top of the base plate 1 of the PCB board separator. Its design purpose is to wrap the entire separator mechanism 7 and the PCB board to be cut. The casing 11 is used to protect the separator mechanism 7 and the control system, while ensuring the safety of the operator. According to the preset cutting program and the instructions of the control system, the separator mechanism 7 starts to cut the PCB board. The structure of the casing 11 ensures safety and stability during the cutting process, while preventing fragments or waste generated by cutting from splashing, thereby reducing the impact of external interference on the cutting process, effectively integrating the separator mechanism 7 and the PCB board, protecting the operating environment and the safety of the operator, and optimizing the control and efficiency of the cutting process.

[0103] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
