In order to quickly, accurately and stably manufacture marks with the same specification on the outer surface of a product clamp by a process, a preferred embodiment of the invention is based on a laser marking machine, and the following processes are developed:
depending on the size and shape of the product holder, in combination with the range of valid markings (e.g. 110mm by 110mm) of the laser marking machine, an 8-station tray as shown in figures 2 and 3 was produced. The tray adopts the material preparation that the light transmissivity is good, good heat dissipation, like ya keli to avoid the tray to absorb or reflect the laser beam when printing, prolong the life of tray.
As shown in fig. 2, at each station of the tray 20, a level of suitable area is provided, and below this level, blind or through holes are provided for receiving the clips 11 provided on the product clips 10. B marks a positioning angle of the tray placed on a plane workbench of the laser marking machine; a1 and A8 identify the first station and the eighth station, respectively, where the tray is placed on the flat table of the laser marking machine.
Specifically, the station adjacent to the station A1 is the first station, the station adjacent to the station A8 is the 8 th station, and other stations are numbered sequentially, for example, the stations are numbered from top to bottom and then from left to right; or numbering from left to right and then from bottom to top.
Correspondingly, when the numbering sequence of the stations is changed, the offset track control algorithm of the galvanometer system is adjusted.
Operating the laser marking machine, and determining positioning marked lines L1 and L2 for indicating the placement position of the positioning angle B on the plane workbench; preferably, the positioning reticles L1 and L2 are perpendicular in the plane of the planar table.
By placing the positioning angle of the tray against the positioning index line according to the instructions of the positioning index lines L1 and L2, it is possible to print the mark at an accurate position on each station in the tray.
And operating the laser marking machine, determining the set height of the laser and the galvanometer system along the vertical direction when the laser beam is focused on the surface of the product clamp after the tray is placed on the plane workbench by means of the side red light source, and locking the height to be fixed during subsequent production.
It will be appreciated that as the size of the tray or label changes, the height of the laser and galvanometer system set in the vertical direction will need to be adjusted again to ensure that the focal point of the laser beam falls on the plane to be printed.
Operating marking control software of the laser marking machine to generate a typesetting template comprising 8 plane marks with the same size, wherein the 8 plane marks are uniformly distributed; the relative distance between these 8 plane marks is adapted to the relative distance between the 8 stations placed by the positioning angle on the tray in the effective printing area formed on the plane table by the laser marking machine.
Setting position control parameters of a galvanometer system (comprising a high-speed scanning galvanometer and a field lens or a field lens) of the laser marking machine, so that 8 movement cycles are sequentially executed in each printing task, and printing of 8 marks is sequentially completed; specifically, during the 8 movement cycles, from the first station to the eighth station, the predetermined planar mark is laser engraved on the surface of the product clamp in the last station of the tray.
Specifically, when the laser marking machine controls the deflection of the galvanometer system to realize high-precision scanning and accurate positioning on the plane workbench, the first station is taken as a zero position, the jumping distances of the rest stations relative to the first station are set according to the distances between the rest stations in the tray and the first station in the X direction and the Y direction, and the position switching among the stations is realized;
or
And the jumping distance between the adjacent stations is set according to the distance between the adjacent stations in the tray in the X direction and the Y direction, so that the position switching between the stations is realized.
And generating a motion control instruction for controlling the galvanometer system to deflect to a zero position corresponding to the station on the tray in sequence from the first station to the eighth station in 8 motion cycles according to the jump distance.
It should be understood that: the plane marks of the laser engravings on the surfaces of the 8 product clamps on the 8 stations have the same size and similar shape; having the same first content, such as a business number, a poster; and different second contents, such as an aquatic product identity number for tracing, such as a two-dimensional code for tracing.
The motion control parameters of the galvanometer system of the laser marking machine are set, namely the scanning speed and the line spacing of the galvanometer, so that the laser marking machine is suitable for different types of identification contents, such as: the low-gray background portion of the two-dimensional code, such as a high-gray text portion, such as a high-gray pattern portion, and the like.
The control parameters of the laser marking machine, such as output power, operating frequency (i.e. modulation frequency), are set such that the laser forms spots of different energy levels at the focal point, which are used to laser engrave a depression of appropriate depth in the surface of the product holder.
It should be understood that the depth of the depression is no greater than 0.5 mm. Preferably, the depth of the laser etching layer ranges from 5um (micrometer) to 20 um.
The following will specifically describe a procedure of printing the plane marks on the surfaces of 80 product clips by using the tray and the laser marking machine (rated power is 30W) with adjusted parameters by using the method of the present embodiment.
Step S10: receiving a file containing 80 aquatic product identification information by a control system of a laser marking machine, wherein the file contains 80 aquatic product identity numbers and source tracing two-dimensional codes which are in one-to-one correspondence with the aquatic product identity numbers;
step S20: firstly, adding the 80 aquatic product identification information into a pre-generated typesetting template in a one-to-one correspondence manner, and generating 10 typesetting templates to be printed; each typesetting template to be printed comprises 8 plane marks to be printed;
step S30: taking an 8-station tray, and putting 8 product clamps with upward front faces to be printed; placing the positioning angle of the tray against the positioning mark line on the plane workbench;
step S40: starting a laser and a galvanometer system (namely a printing position control assembly), specifically, clicking a marking button in a marking control interface to start the laser to work, and starting the galvanometer system to work to start position scanning;
in a first typesetting template to be printed, the offset track of a galvanometer system is sequentially divided into 8 movement periods, and a first group of 8 plane marks to be printed are printed on a product clamp in a tray;
step S50: stopping the laser and the galvanometer system, or controlling the laser and the galvanometer system to stand by and wait:
taking away the tray with the printed label;
placing the positioning angles of the tray on which the 8 product clamps to be printed with the upward front faces are placed against the positioning mark lines on the plane workbench;
step S60: starting or awakening a laser and a galvanometer system;
in the typesetting template to be printed next, the offset track of the galvanometer system is sequentially divided into 8 movement periods, and 8 plane marks to be printed in the next group are printed on the product clamps in the tray one by one;
the steps S50-S60 are repeated until all 10 jobs to be printed are completed.
It should be understood that another tray of 8 product folders to be printed with the front side facing upward may be prepared and placed in advance when the current imposition template to be printed is valid, so that the tray is replaced in time after the end of the current print job.
Preferably, when a predetermined plane mark is printed on the surface of a product clamp placed in any station, the laser and the galvanometer system are controlled to complete a low-gray background part in the two-dimensional code in the mark according to a first group of working parameters; and then controlling the laser and the galvanometer system to complete the high-gray foreground part in the two-dimensional code in the mark and other high-gray character parts in the mark by using a second group of working parameters.
Specifically, the time required for the laser and the galvanometer system to complete the background part with low gray in the two-dimensional code in the identification by using the first group of working parameters is T1, and the time required for the laser and the galvanometer system to complete the foreground part with high gray in the two-dimensional code in the identification and other character parts with high gray in the identification by using the second group of working parameters is T2; the time for focusing the galvanometer system from the current station to the position zero position of the next station is T3;
each movement cycle in each job to be printed lasts at least the sum of T1, T2, and T3.
And after the last movement period is finished, the galvanometer system is restored to the zero position corresponding to the first station.
It should be appreciated that if the number of identifiers to be printed is not an integer multiple of the number of stations in the tray, the settings of the marking control software may be adjusted to accomplish batch printing of the last group of identifiers less than N. Specifically, in the current typesetting template to be printed, all identifiers smaller than N to be printed are framed; after the option of 'selecting printing' is selected in the marking control interface, the 'marking' button is clicked, the laser is started to work, the galvanometer system is started to work, and batch printing of the appointed marks smaller than N is completed.
Specifically, when the product clamp is a food-grade stainless steel plate with the thickness of 0.5mm or 0.3mm, the laser and the galvanometer system adopt the following working parameters to complete the background part of the two-dimensional code in the mark: line spacing, 0.1 mm; scanning speed, 2000 mm/s; power ratio, 30%; the modulation frequency is 50 kHz. At this moment, the laser etching speed is high, the power of a laser beam is low, the energy of a light spot is low, and the surface of the processed stainless steel is white.
The laser and the galvanometer system adopt the following working parameters to complete the foreground part in the two-dimensional code in the mark and other character parts in the mark: line spacing, 0.05mm or 0.1 mm; scanning speed, 550 mm/s; power ratio, 70%; modulation frequency, 20 kHz. At this time, the laser etching speed is slow, the power of the laser beam is high, the energy of the light spot is high, and the surface of the processed stainless steel is dark brown and is approximately black.
The mark manufactured by the process has clear pattern boundary, clear text routing and no fuzzy number; the surface of the product clamp is basically free from warping or the warping is not obvious; the human eye identification degree is high, and the scanning identification degree of the two-dimensional code is high; the identification is not easily broken by man or maliciously modified. The mark of the product clamp of the aquatic product can greatly improve the identifiability and traceability of the aquatic product and ensure the food safety of the aquatic product
The method for manufacturing the mark on the surface of the product clamp has the advantages of high processing speed, high automation degree and good process stability.
In summary, when the product clamp made of the stainless steel sheet is subjected to laser etching on the surface for the aquatic product traceability marking, the method roughly comprises the following steps:
