[0036] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0037] The cutting device 10 provided in the embodiment of the present invention is used for the cutting process in SMT proofing and small batch order operation; of course, in other embodiments of the present invention, the cutting device 10 can also be used to cut other materials, or applied to other processing procedures of other materials, which is not the only limitation here.

[0038] Please combine Figures 1 to 7, the dividing device 10 provided by the present invention is now described. A dividing device 10, the dividing device 10 includes an adjustment mechanism 100, a conveying member 200 and a dividing member 300. The adjustment mechanism 100 is provided with a conveying space. The conveying space is used for conveying materials, and its shape and size need to match the shape and size of the materials, and play a certain guiding role, so that the materials are smoother during the conveying process to avoid the materials from getting stuck. In this embodiment, the adjustment mechanism 100 includes a first slider 110 and a second slider 120, and the first slider 110 and the second slider 120 can move relative to each other to adjust the conveying space to adapt to different material sizes. A support member 124 is provided on the second slider 120. The conveying member 200 and the support member 124 are located on one side of the first slider 110 and are both arranged opposite to the first slider 110. The conveying member 200 is used to convey the material to move along the conveying space, and the material includes at least a dividing station on its moving path. The dividing member 300 is used to divide the material at the dividing station. The above-mentioned cutting device 10 adopts an adjustment mechanism 100 having a first slider 110 and a second slider 120. The adjustment mechanism 100 can adjust the conveying space to adapt to different material sizes through the first slider 110 and the second slider 120; at the same time, a support member 124 is provided on the second slider 120, and the support member 124 and the conveying member 200 are arranged opposite to the first slider 110. Since the support member 124 and the conveying member 200 are located on the same side of the first slider 110, when the conveying member 200 conveys materials, the support member 124 can be used to support the materials to assist the conveying member 200 in conveying materials, so as to prevent the materials from being stuck when the materials are tilted too much or the thickness of the materials are different during the conveying process.

[0039] In one embodiment, the cutting device 10 further includes a shell 400. In this embodiment, the shell 400 is a split structure, including an upper shell 410 and a back cover 420. Further, the first slider 110 is slidably connected to the shell 400, and the first slider 110 can move relative to the shell 400 along a first direction, and the second slider 120 is slidably connected to the first slider 110, and the second slider 120 can move relative to the first slider 110 along a second direction and move toward the shell 400, and the first direction is perpendicular to the second direction. In this embodiment, the first slider 110 and the second slider 120 can adjust the conveying space from the first direction and the second direction, and the conveying space relative to the second slider 120 is limited by the shell 400 on one side, and the conveying space relative to the first slider 110 is formed by the conveying member 200 and the support member 124 on the other side, forming a relatively sealed conveying space. The first slider 110 and the second slider 120 can limit the conveying space to a size that matches the material size through mutual cooperation with the shell 400 and the conveying member 200, thereby ensuring stable transmission of the material. In this embodiment, the first direction is parallel to Figure 3 The direction indicated by the arrow X in the middle, the second direction is parallel to Figure 3 The arrow Y in the middle points to the direction.

[0040] On the basis of the above embodiment, the housing 400 is provided with a slide groove 411 extending along the first direction, and the adjustment mechanism 100 further includes a moving block and a fixed block 412. The moving block is accommodated in the slide groove 411, and the first slider 110 is connected to the moving block and moves along the slide groove 411 through the moving block. The moving block is fixedly connected to the housing 400 through the fixed block 412 to fix the first slider 110 to the housing 400. In this way, after the position of the first slider 110 is adjusted, it can be fixed by the fixed block 412 to stabilize the position of the first slider 110 and avoid movement during the subsequent material conveying process to affect the material conveying. At the same time, the first slider 110 and the moving block are detachably connected, which is convenient for replacing the type of the first slider 110 to adapt to the conveying of different materials.

[0041] Please combine Figures 5 to 7 Preferably, the first slider 110 is provided with a groove 111 extending along the second direction, the second slider 120 is partially received in the groove 111 and can move relative to the first slider 110 along the groove 111, and the adjustment mechanism 100 also includes a positioning assembly 130, which is connected to the second slider 120 for fixing the second slider 120 with the first slider 110. In this way, after the position of the second slider 120 is adjusted, the second slider 120 can be fixed to the first slider 110 by the positioning assembly 130, so that the position of the second slider 120 is stable, and the second slider 120 is prevented from moving and affecting the material conveying during the subsequent material conveying process. In this embodiment, the cross section of the first slider 110 is L-shaped, and the first slider 110 includes a sliding portion 112 extending along the first direction and fitting with the housing 400 and a supporting portion 113 extending along the second direction, and the groove 111 is formed on the supporting portion 113. In this way, the sliding portion 112 can ensure the stability of sliding with the housing 400, and improve the service life of the first slider 110. The cross section of the groove 111 perpendicular to the second direction is T-shaped. The second slider 120 includes a moving portion 121 matching the groove 111 and a limiting portion 122 for limiting the conveying space. The moving portion 121 cooperates with the groove 111 to improve the stability of the second slider 120 when sliding relative to the first slider 110. Further, the limiting portion 122 is asymmetrically connected to the sliding portion, and the limiting portion 122 has an extension section 1221 extending toward the starting side of the material conveying. Since the groove 111 and the matching moving portion 121 are both T-shaped, the extension section 1221 can cooperate with the moving portion 121 to clamp the first slider 110 corresponding to the groove 111, so as to further improve the stability of the relative sliding of the first slider 110 and the second slider 120. At the same time, the extension section 1221 can partially extend the length of the conveying space, limit the path of material conveying, and improve the stability of material conveying.

[0042] Please continue reading Figure 5 and Figure 6 On the basis of the above-mentioned embodiments, the first slider 110 is provided with a first through slot 114 connected with the groove 111, and the first through slot 114 extends along the second direction. That is, the first through slot 114 penetrates the first slider 110 along the first direction. The positioning assembly 130 includes a connecting member 131, a rotating member 132 and a stopper 133. In this embodiment, the first through slot 114 penetrates the support portion 113 along the first direction and is connected with the groove 111. The connecting member 131 is a screw. The connecting member 131 is threadedly connected to the second slider 120 through the first through slot 114. The rotating member 132 is a hand wheel. The rotating member 132 is sleeved on the connecting member 131, and the limiting member 133 is sleeved on the connecting member 131. The limiting member 133 is located between the first slider 110 and the rotating member 132. The rotating member 132 can drive the connecting member 131 to rotate into the second slider 120 and abut the limiting member 133 against the first slider 110, so as to fix the second slider 120 with the first slider 110. When the position of the second slider 120 needs to be adjusted, the rotating member 132 rotates in the opposite direction to drive the connecting member 131 to rotate relative to the second slider 120. At this time, the length of the connecting member 131 between the first slider 110 and the rotating member 132 is greater than the length of the limiting member 133, and the limiting member 133 is released, so that the second slider 120 can move relative to the first slider 110 again. Due to the existence of the limit member 133, the first slider 110 and the second slider 120 can be locked at a long distance to ensure that when the rotating member 132 drives the connecting member 131, the operator does not touch the first slider 110, thereby preventing the first slider 110 from moving relative to the housing 400.

[0043] Preferably, the second slider 120 is provided with a second through slot 123, and the second through slot 123 extends along the first direction. That is, the second through slot 123 passes through the second slider 120 along the second direction. The support member 124 is provided in the second through slot 123 and can move along the first direction. In this way, the support member 124 can adjust the distance between the support member 124 and the first slider 110 along the first direction, and fine-tune the conveying space to further adapt to the material size.

[0044] Please combine Figures 1 to 4 , a protrusion 201 is provided on the conveying member 200 to prevent the conveying member 200 from moving relative to the material. In this embodiment, the conveying member 200 is a gear structure, and its tooth structure constitutes the protrusion 201. The cutting device 10 also includes a driving mechanism, which includes a motor 210, and the output end of the motor 210 is connected to one end of a transmission shaft 230 through a coupling 220, and the other end of the transmission shaft 230 is connected to the conveying member 200, and is used to drive the conveying member 200 to rotate to transport the material. The motor 210, the coupling 220 and the transmission shaft 230 are accommodated in the housing 400, and the transmission shaft 230 is rotatably connected to the housing 400 through a sleeve 240.

[0045] In this embodiment, the cutting device 10 is used as follows Figure 5 Preferably, the conveying member 200 is closer to the first slider 110 than the supporting member 124. In this way, during the material conveying process, the upper end of the material can overlap on the supporting member 124, which guides the material and prevents the material from getting stuck when the material is tilted too much or the material thickness is different during the material conveying process.

[0046] like Figure 6 As shown, the first slider 110 is provided with an avoidance groove 115 for avoiding the dividing member 300. In this way, the dividing member 300 can pass through the conveying space, ensuring that the dividing member 300 can completely divide the material when dividing the material. In this embodiment, the dividing member 300 is rotatably connected to the housing 400 through the tool holder 310, and the dividing member 300 is provided with a dividing driving unit for driving the dividing member 300 to divide.

[0047] Furthermore, the cutting device 10 also includes a control unit 500 and a switch 600 for turning on the cutting device 10. The control unit 500 is used to control the conveying member 200 to convey materials and to control the cutting member 300 to cut materials according to the cutting information. In this embodiment, the control unit 500 includes a housing, a display screen 510 and a button 520 arranged on the housing, and the cutting information can be manually input through the button 520 and the display screen 510. The cutting information includes but is not limited to the material strip spacing, width and the number of cuts required for the cut material. The cutting information can also be obtained by scanning the barcode on the material and identifying the material by connecting the PC through the communication protocol, and the material strip spacing, width and the number of cuts required are obtained by the control unit 500. The cutting device 10 also includes a sensor 700, which is used to verify whether the number of cuts meets the requirements.

[0048] Please combine Figures 1 to 8 The embodiment of the present invention further provides a segmentation method, which comprises the following steps:

[0049] Adjust the conveying space to suit different material sizes;

[0050] Get segmentation information;

[0051] Determine the number of cuts and the step distance before each cut according to the cut information;

[0052] The material is driven to be transported to the cutting station according to the number of cutting times and the stepping distance, and the material at the cutting station is cut.

[0053] Furthermore, the specific steps to adjust the conveying space to accommodate different material sizes are as follows:

[0054] According to the size of the material, the positions of the first slider 110, the second slider 120 and the support member 124 are adjusted so that the conveying space meets the size of the material.

[0055] Furthermore, the specific steps for obtaining the segmentation information are as follows:

[0056] The cutting information can be manually input through the display screen 510 and the button 520 of the control unit 500. The cutting information includes but is not limited to the material strip spacing, width and the number of cuttings required. The cutting information can also be obtained by the control unit 500 through the communication protocol connection PC from other systems such as the enterprise resource planning system (ERP) or the manufacturing execution system (MES) and the barcode on the material by scanning the barcode to identify the material, the material strip spacing, width and the number of cuttings required.

[0057] Furthermore, the specific steps of determining the number of segmentation and the stepping distance before each segmentation according to the segmentation information are as follows:

[0058] The control unit 500 automatically converts the cut-off number and the stepping distance before each cut-off according to the cut-off information, that is, obtains the operation cycle of the motor 210 and the cut-off drive unit. For example, the angle of each rotation of the motor 210 can be obtained according to the stepping distance to match the distance of each material conveying.

[0059] Furthermore, the specific steps of driving the material to be transported to the cutting station according to the number of cutting times and the stepping distance and cutting the material at the cutting station are as follows:

[0060] The control unit 500 controls the conveying member 200 to convey materials and controls the cutting member 300 to cut materials according to the number of cutting times and the stepping distance before each cutting.

[0061] Furthermore, the cutting device 10 further includes a sensor 700, which is used to verify whether the number of cuts meets the requirement. When the sensor 700 verifies that the number of corresponding cuts meets the required number of cuts, the cutting member 300 cuts the material under the drive of the cutting drive unit, and the raw material tray is automatically recovered; the cut material is simultaneously rolled into a matching blank material tray for marking and standby use.

[0062] Furthermore, after the cutting is completed, the material number, specification and quantity of the cut material are automatically obtained, and the unique tracking barcode of this material is generated according to the established rules, and transmitted to the coding printer to print out the barcode, which is attached to the unmarked material tray where the cut material is stored, so that the production system can scan the barcode gun to identify and match the corresponding production order PO, and automatically connect and match with the error-proofing system to ensure the accuracy of the materials used. At the same time, the quantity of the barcode corresponding to the raw material tray is automatically deducted. This number can be manually revised on the raw material tray, or a new barcode can be regenerated using a barcode printer to cover it to show the latest material quantity, so as to ensure the consistency of the account and actual storage materials for the next use or automatic inventory.

[0063] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
