Figure 1

[0008] Preferably, when it is determined that the distance between the adjacent products is not less than the distance threshold value, it is determined that the distance between the adjacent products meets the cutting requirement; when it is determined that the distance between the adjacent products is less than the distance threshold value, it is determined that the distance between the adjacent products does not meet the cutting requirement; The distance threshold value is determined according to the following formula: ; wherein L is the distance threshold value, R is the radius of the cutter of the cutting mechanism, H is the thickness of the product, h is the cutting depth of the cutter on the base film, and m is a set control amount.

[0009] Preferably, the product front allowance for determining the cutting start position and the product rear allowance for determining the cutting end position are L / 2.

[0010] Preferably, before determining the distance between the adjacent products, it is determined through image recognition whether the long side or the short side of each product on the piece to be cut is parallel, if it is determined that the long side or the short side of the adjacent products is parallel, the distance between the adjacent products is determined, and if it is determined that the long side or the short side of the adjacent products is not parallel, the determination of the distance between the adjacent products is stopped.

[0011] Preferably, when it is determined that the long side or the short side of each product is parallel, it is determined through image recognition whether the long side or the short side of the product extends along the X-axis direction or the Y-axis direction, if yes, the distance between the adjacent products is determined, and if no, the cutting table is rotated to make the long side or the short side of the product extend along the X-axis direction or the Y-axis direction before the distance between the adjacent products is determined.

[0012] Preferably, before the cutting mechanism is controlled to cut, the main shaft is controlled to operate at a predetermined cutting speed, and it is determined whether the vibration values detected by the vibration detection components close to both ends of the main shaft are all not more than a vibration threshold value, if yes, it is determined that the main shaft is normal, and the cutting continues, and if no, it is determined that the main shaft is abnormal, and the cutting is stopped.

[0013] Preferably, the vibration detection components include an axial detection sensor and a radial detection sensor.

[0014] A multi-piece product cutting system, comprising: a fixing unit for controlling a cutting table to fix a piece to be cut thereon, the piece to be cut comprising a base film and a plurality of products attached side by side and spaced apart on the base film; An image recognition unit is configured to determine whether the distance between adjacent products meets the cutting requirement, and when the distance between adjacent products meets the cutting requirement, the cutting mechanism will not cut the adjacent product when cutting one product according to the set cutting start position and cutting end position. A cutting unit is configured to control the cutting mechanism to cut each product in sequence when it is determined that the distance between adjacent products meets the cutting requirement. An alarm unit is configured to pause the cutting when it is determined that the distance between adjacent products does not meet the cutting requirement.

[0015] A method for pasting a plurality of products on a film comprises the following steps: A plurality of products are pasted on the bottom film on the film frame in parallel and at intervals to obtain a product to be detected; It is determined whether the distance between adjacent products on the product to be detected meets the cutting requirement, and when the distance between adjacent products meets the cutting requirement, the cutting mechanism will not cut the adjacent product when cutting one product according to the set cutting start position and cutting end position. When it is determined that the distance between adjacent products on the product to be detected meets the requirement, the product to be detected is placed in a qualified product box. When it is determined that the distance between adjacent products on the product to be detected does not meet the requirement, an abnormality is handled.

[0018] The distance threshold determination formula of the present application considers various factors, can provide accurate reference for product distance recognition, and thus ensures the accuracy of judgment. Meanwhile, in combination with the control of the product front reserve and the product rear reserve, the cutting knife will not contact any product when it is lowered to the cutting height, thereby effectively avoiding the problem that the product to be cut is damaged due to discontinuous cutting action.

[0019] The application determines whether the long side or the short side of the two products is parallel before determining the distance, so that the product state can be more quickly identified whether there is an abnormality, thereby avoiding the influence of the inaccurate position of the measured distance on the judgment accuracy when the product state is abnormal, and being beneficial to guarantee the accuracy of identification. Before determining the distance, the extension direction of the long side or the short side of the product is also determined, so as to ensure that the extension direction of the long side or the short side of the product matches the axial direction of the cutter, thereby ensuring safe cutting of the product.

[0020] When it is determined that the distance between the adjacent products meets the cutting requirement, the main shaft is first operated at a predetermined cutting rotating speed, and the axial detection sensor and the radial detection sensor are used to detect whether the vibration of the main shaft is abnormal, and when it is determined that the vibration is abnormal, the cutting is paused, so that the influence of the large cutter vibration on the cutting accuracy can be effectively avoided, and the cutting into two products can be further avoided.

DETAILED DESCRIPTION

[0022] The purposes, advantages and characteristics of the application will be illustrated and explained by the following non-limiting description of the preferred embodiments. These embodiments are only typical examples of the application of the technical solutions of the application, and any technical solutions formed by equivalent replacement or equivalent transformation all fall within the scope of the application.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example 1

[0024] The method for cutting multiple products disclosed in this invention will be described below with reference to the accompanying drawings. Figure 1 As shown, the multi-piece product cutting method includes an annular film frame 110, a base film 120 attached to the film frame 110, and multiple pieces of product 130 attached side by side and spaced apart to the base film 120.

[0025] The multi-piece product cutting method is based on a dicing device, as shown in the attached figure. Figure 2 As shown, similar to existing dicing equipment, it includes: The cutting table (not shown in the figure) is used to place and fix the workpiece 100 to be cut. It uses vacuum adsorption to adsorb and fix the bottom film 120 of the workpiece 100 to be cut, and uses a ring of gripper assembly to fix the film frame 110 where the bottom film 120 is located.

[0026] The first moving mechanism 200 drives the cutting table to translate between the loading / unloading position and the cutting position, and drives the cutting table to rotate. Its specific structure is known technology and will not be described in detail here.

[0027] The cutting mechanism 300 includes a second moving mechanism 310 and a main shaft 320 driven by the second moving mechanism 310 to move horizontally and vertically. The specific structure of the second moving mechanism 310 is known technology and will not be described in detail here. The second moving mechanism drives the main shaft 320 to translate along the axis of the main shaft, which is defined as the Y-axis direction. The direction in which the first moving mechanism 200 drives the cutting table to translate is defined as the X-axis direction, which is perpendicular to the Y-axis direction. The main shaft 320 is connected to a cutter 330 that is driven to rotate by it.

[0028] The cutting control device 400 is connected to the cutting table, the first moving mechanism and the cutting mechanism 300, and controls their operation.

[0029] The cutting control device 400 is further connected with a visual detection assembly 500, which for example comprises an industrial camera, a lens, a light source and the like, and is arranged on the side of the main shaft or on a second moving mechanism and moves synchronously with the main shaft. The visual detection assembly 500 collects images of the to-be-cut piece 100 on the cutting table. The cutting control device 400 performs image recognition according to the images collected by the visual detection assembly 500. The specific content of the image recognition can be determined as required, for example, the position coordinates of the top corners of each product on the to-be-cut piece can be recognized, which is not limited here.

[0030] As shown in FIGS. 1 to 3, the multi-piece product cutting method comprises the following steps: Figure 3 Figure 4 As shown in FIGS. 1 to 3, the multi-piece product cutting method comprises the following steps: The to-be-cut piece 100 is placed on the cutting table in a predetermined state by manual operation or through an automatic device (a loading and unloading robot).

[0031] After the to-be-cut piece 100 is placed on the cutting table, the cutting table is controlled to fix the to-be-cut piece 100 thereon.

[0032] The visual detection assembly 500 is controlled to collect images of the to-be-cut piece 100 on the top of the cutting table and determine whether the distance between the adjacent products 130 in the to-be-cut piece 100 meets the cutting requirement through image recognition. When the distance between the adjacent products meets the cutting requirement, the cutting mechanism 300 will not cut the adjacent product 130 when cutting one product 130 according to the set cutting start position and cutting end position.

[0033] When it is specifically determined whether the distance between the adjacent products 130 meets the cutting requirement, it is determined whether the distance between the adjacent products 130 is less than a distance threshold value. When it is determined that the distance between the adjacent products 130 is not less than the distance threshold value, it is determined that the distance between the adjacent products 130 meets the cutting requirement. When it is determined that the distance between the adjacent products 130 is less than the distance threshold value, it is determined that the distance between the adjacent products 130 does not meet the cutting requirement. The specific method for determining the distance between the adjacent two products 130 through image recognition is known technology and is not the innovation of the present application, which is not described here.

[0034] As shown in FIGS. 1 to 3, the multi-piece product cutting method comprises the following steps: Figure 5 ​As shown, when the cutter 330 is tangent to the first upper corner A and the second upper corner B of the two adjacent products 130, the distance AB between the first upper corner A and the second upper corner B is the distance between the two products 130, the distance OA from the center O of the cutter 330 to the first upper corner A is equal to the distance OB from the center O of the cutter 330 to the second upper corner B, which is equal to the radius R of the cutter 330, and the radius R of the cutter 330 is equal to the thickness H of the product 130 plus the cutting depth h of the cutter 330 on the bottom film. When the cutting is in place, the distance OC from the center O of the cutter 330 to the top surface of the product 130 is OC = H + h, and then OC = R. ， At the same time, point C is the midpoint of the connection AB of the first upper corner A and the second upper corner B, that is, AC = BC, and according to the Pythagorean theorem, then, Therefore, .

[0035] At the same time, considering that various errors will affect the position accuracy, the distance threshold is determined according to the following formula: ; Wherein, L is the distance threshold, m is the set control amount, which is determined by considering various factors such as equipment accuracy error and film placing error, and is preferably 4.5 mm. Under this set control amount, when cutting at the cutting start position and the cutting end position, the cutter can be prevented from contacting any adjacent product.

[0036] When the distance between the adjacent products 130 meets the cutting requirement, the cutting mechanism 300 is controlled to cut each product 130 in turn; For example, when there are only two products 130 on the cutting piece 100, it is only necessary to determine that the distance between the two products 130 meets the cutting requirement. When the number of products 130 on the cutting piece 100 is greater than 2, for example, the cutting piece 100 includes 3 products 130, which are defined as No. 1 product, No. 2 product and No. 3 product from left to right. At this time, it is necessary to determine that the distance between the No. 1 product and the No. 2 product and the distance between the No. 2 product and the No. 3 product meet the cutting requirement.

[0037] The specific process of controlling the cutting mechanism to cut is known technology and is not the innovation of the present application, which will not be described here.

[0038] On the contrary, when it is determined that the distance between any two adjacent products 130 does not meet the cutting requirement, the cutting is paused, and the staff can be reminded by alarm, or the cutting piece on the cutting table can be transferred to the abnormal piece box for storage by the feeding and discharging robot, and the cutting of the next cutting piece is processed.

[0039] Correspondingly, the allowance A in front of the product used to determine the starting position of the cutting is... 前 And the allowance A behind the product used to determine the end position of the cutting 后 This ensures that, regardless of whether the cutting starts or ends, when the cutter 330 moves down to the cutting height, it will be positioned between two adjacent products 130 and maintain a distance from them, thus effectively guaranteeing the safety of the cutting process.

[0040] As attached Figure 6 As shown, before determining the spacing between adjacent products 130, image recognition is used to determine whether the long or short sides of each product 130 on the workpiece to be cut are parallel. The specific image processing method for determining whether the long or short sides of each product 130 are parallel is a known technology and is not an innovation of this invention, so it will not be described in detail here.

[0041] If it is determined that the long or short sides of all products 130 are parallel (i.e., all products have parallel long or short sides), then the spacing between adjacent products 130 is determined. If it is determined that the long or short sides of any two products 130 are not parallel (i.e., any two products have parallel long or short sides), then the determination of the spacing between adjacent products is paused. In this case, an alarm can be triggered to prompt manual intervention, or the parts to be cut can be transferred to the abnormal parts box by a loading and unloading robot for processing the next part. This avoids product 130 skewing affecting cutting quality and ensures that the spacing between adjacent products 130 determined by image recognition is accurate.

[0042] As attached Figure 6 As shown, since the axis of the cutter on the spindle is fixed, determining that the long or short sides of each product 130 are parallel does not guarantee that the extension direction of the long or short sides of each product matches the axis of the cutter. Therefore, when determining that the long or short sides of each product 130 are parallel, it is necessary to further determine whether the long or short sides of the product extend along the X-axis or Y-axis direction through image recognition. (See attached image.) Figure 2As shown, when the to-be-cut products are placed on the cutting table, the long edges of the products will theoretically extend along the Y-axis direction after the cutting table is adjusted by a known edge-finding method. Therefore, when the long edges or the short edges of each product 130 are determined to be parallel, it can be determined by image recognition whether any long edge of any product extends along the Y-axis direction, and if so, the distance between adjacent products can be determined, and if not, i.e., the long edges of each product maintain a certain angle with the Y-axis direction, the cutting table can be controlled to rotate according to the angle between the long edges and the Y-axis direction, so that the products are rotated to have their long edges extending along the Y-axis direction, and then the distance between adjacent products can be determined. Here, the specific image recognition method for identifying whether the long edges or the short edges of the products extend along the Y-axis direction or the X-axis direction and determining the angle between the long edges or the short edges of the products and the Y-axis direction or the X-axis direction is a known technology and is not the innovation of the present application, and will not be described here.

[0043] Since the distance between the cutting knife and the products 130 is small and the cutting path on the products 130 is narrow at the cutting start position and the cutting end position, and the cutting knife 330 will have significant vibration due to unqualified dynamic balance or axial movement of the main shaft 320 during cutting, thereby affecting the cutting accuracy of the cutting knife 330 and increasing the risk of cutting the cutting knife 330 to two adjacent products 130, as shown in the appended Figure 7 As shown, a vibration detection assembly 340 is arranged at the positions close to the two ends of the main shaft 320, the vibration detection assembly 340 includes a fixed frame 341 which is approximately C-shaped and surrounds the top of the main shaft, the two ends of the fixed frame 341 are connected to the main shaft 320 by fastening bolts, the axis of the fastening bolts extends horizontally and is perpendicular to the axis of the main shaft 320, and an axial detection sensor 342 and a radial detection sensor 343 are arranged on the fixed frame 341, the axial detection sensor 342 and the radial detection sensor 343 can be known vibration sensors, and the axial detection sensor 342 is arranged on one side of the fixed frame 341, and the radial detection sensor 343 is arranged on the top of the fixed frame 341.

[0044] As shown in the appended Figure 8As shown, before the cutting mechanism 300 cuts, the control spindle 320 is controlled to rotate at a predetermined cutting speed, and it is determined whether the vibration values detected by the two vibration detection components 340 close to the two ends of the spindle 320 are both less than a first vibration threshold value. If yes, it is determined that the spindle 320 is normal, and the cutting continues. If no, it is determined that the spindle 320 is abnormal, and the cutting is stopped. The first vibration threshold value is, for example, 0.02 mm / s. When the vibration value detected by any one of the axial detection sensor 342 and the radial detection sensor 343 exceeds the vibration threshold value, it is determined that the spindle 320 is abnormal, and the cutting is not performed and an alarm is given to remind manual processing. Conversely, when the vibration values detected by the axial detection sensor 342 and the radial detection sensor 343 are both less than the vibration threshold value, it is determined that the spindle 320 is normal, and the cutting can be started.

[0045] During the cutting process, the vibration values detected by the axial detection sensor 342 and the radial detection sensor 343 can be continuously acquired, and it is determined whether the vibration values detected by the axial detection sensor 342 and the radial detection sensor 343 exceed a cutting vibration threshold value, for example, 0.05 mm / s. If yes, it is determined that the cutting is abnormal, and the cutting is stopped and an alarm is given to remind manual processing. Conversely, the cutting continues. Embodiment 2
