[0017] The following will illustrate the implementation methods of the utility model in conjunction with the drawings in the specification. It should be noted that the implementation methods involved in this specification are not exhaustive and do not represent the only implementation methods of the utility model. The following corresponding embodiments are only for the purpose of clearly illustrating the utility model content of the utility model patent, and are not intended to limit its implementation methods. For ordinary technicians in this field, different forms of changes and modifications can be made on the basis of the description of this embodiment. All obvious changes or modifications that belong to the technical concept and utility model content of the utility model are also within the scope of protection of the utility model.

[0018] like Figure 1 As shown, an embodiment of the utility model provides a front and back coding machine for a substrate, including a feed channel 1100 , a discharge channel 1200 , a coding platform 1300 and a laser coding station 1400 .

[0019] The feed channel 1100 and the discharge channel 1200 are arranged in parallel.

[0020] The feed channel 1100 is used to transport the substrate from the back to the front. Exemplarily, the feed channel 1100 may be composed of a pair of synchronously rotating conveying belts driven by a motor. Since it is a conventional structure, it will not be described in detail here.

[0021] A substrate information acquisition head 1110 is provided above the feed channel 1100 . The substrate information acquisition head 1110 may be a camera that acquires the identity information of the substrate through visual technology.

[0022] The discharge channel 1200 is used to receive the coded substrate from the coding platform 1300, and includes a substrate turning section and a detection section.

[0023] like Figure 1 and Figure 2 As shown, the substrate turning section includes two pairs of first conveying belts ( 1210 and 1220 ), a turning mechanism 1230 , and a first stopping mechanism 1240 .

[0024] Two pairs of first conveyor belts (1210 and 1220) are arranged vertically and spaced apart. Figure 2 and Figure 3 As shown, taking a pair of first conveyor belts 1210 as an example, the two are arranged at intervals on the left and right, and the motor 1211 is transmitted to the rotating shaft 1213 through the transmission belt 1212. The rotating shaft 1213 cooperates with the tensioning wheel 1214 to transmit the transmission to the first conveyor belt 1210 on the right. At the same time, the rotating shaft 1213 is transmitted to the first conveyor belt 1210 on the left, thereby realizing the synchronous rotation of a pair of first conveyor belts 1210. Similarly, the synchronous rotation of a pair of first conveyor belts 1220 can be realized, which will not be repeated here.

[0025] like Figure 2 and Figure 3 As shown, the flipping mechanism 1230 is used to synchronously flip two pairs of first conveyor belts (1210 and 1220) so that one pair of the first conveyor belts is in a working position. It includes two left and right support seats 1231, two left and right support plates 1232 and a flipping drive motor 1233. The left and right support plates 1232 are connected by a crossbeam 1234, wherein the left support plate 1232 is connected to the output shaft of the flipping drive motor 1233, and the right support plate 1232 is rotatably connected to the right support seat 1231 through a rotating shaft 1232a, and the flipping drive motor 1233 is fixed to the left support seat 1231.

[0026] The output shaft of the flip driving motor 1233 can be connected to the rotating shaft on the left support plate 1232 through a worm gear mechanism.

[0027] Two pairs of first conveyor belts (1210 and 1220) are arranged on opposite surfaces of the left and right support plates 1232 at intervals in the upper and lower directions.

[0028] The first stop mechanism 1240 is composed of a stop plate 1241 , which can be raised and lowered under the drive of a cylinder 1242 , and the cylinder 1242 is fixed on the crossbeam 1234 .

[0029] When the substrate flipping section is working, only one pair of the two pairs of first conveying belts (1210 and 1220) is in the working position, and the pair of first conveying belts in the working position conveys the substrate. At this time, the substrate 2 is supported by the support bar 1250 located between the pair of first conveying belts. The support bar 1250 is fixed on the beam 1234, and a plurality of pulleys 1251 are arranged on it to reduce the friction between the support plate 2. When the substrate 2 needs to be flipped, the flipping mechanism 1230 works to flip the other pair of first conveying belts to the working position. During the flipping process, the first stop mechanism 1240 stops the end of the substrate to prevent the substrate from falling off.

[0030] like Figure 1 As shown, the detection section includes a pair of third conveyor belts (not shown in the figure) and a laser code quality detection head 1260.

[0031] A pair of third conveyor belts are flush with a pair of first conveyor belts (1210 or 1220) in the working position. The laser code quality detection head 1260 is used to detect the quality of the laser code on the substrate received from the coding platform 1300. It is arranged above the third conveyor belts through a forward, backward, left and right moving module.

[0032] like Figure 1 and Figure 4 As shown, the coding platform 1300 is located at the front side of the feed channel 1100 and is driven by the front, back, left, and right horizontal linear moving modules 1500, so that it can move horizontally to the feed channel docking position, the discharge channel docking position or the coding position.

[0033] Among them, Figure 4 and Figure 5 As shown, the coding platform 1300 includes a pair of second conveying belts 1310 , a second stopping mechanism 1320 , an aligning mechanism 1330 , a vacuum suction plate 1340 , and a lifting and pressing plate 1350 .

[0034] A pair of second conveyor belts 1310 are arranged on the fixed frame 1360 at intervals on the left and right sides, and the bottom plate 1361 of the fixed frame 1360 is fixed on the front, back, left, and right horizontal linear moving modules 1500.

[0035] The second stop mechanism 1320 is used to stop the substrate at the front side of the pair of second conveyor belts 1310. In this embodiment, the second stop mechanism 1320 is two stop blocks respectively located at the front side of the pair of second conveyor belts 1310. Figure 5 .

[0036] The alignment mechanism 1330 is used to align the substrates on the pair of second conveyor belts 1310 front and back and left and right. It includes two first alignment blocks 1331 located at the rear side of the pair of second conveyor belts 1310 and two second alignment blocks 1332 located at the right side of the pair of second conveyor belts 1310. The first alignment block 1331 can move forward and backward under the drive of the first alignment cylinder 1333, and the second alignment block 1332 can move left and right under the drive of the second alignment cylinder 1334. Figure 5 .

[0037] The vacuum suction plate 1340 is used to absorb and lift the substrate on the pair of second conveyor belts 1310 to the coding preparation position, and is located between the pair of second conveyor belts 1310 .

[0038] like Figure 5As shown, the vacuum suction plate 1340 is supported by the nut blocks 1341a of four screw mechanisms 1341, and the four screw mechanisms 1341 are arranged on the base plate 1361, and the screw shafts 1341b are all in the up and down direction, and the lower ends of the screw shafts 1341b of the four screw mechanisms 1341 are provided with pulleys 1341c, and the four pulleys 1341c are synchronously driven by the screw drive motor 1342 via the transmission belt 1343 and multiple tensioning wheels 1344, thereby realizing the lifting and lowering of the vacuum suction plate 1340.

[0039] like Figure 4 As shown, the lifting and pressing plate 1350 is used to press down the substrate on the vacuum suction plate 1340 to prevent the substrate from warping and affecting subsequent coding.

[0040] The lifting and pressing plate 1350 includes a square frame 1351 , on which a cross-shaped connecting strip 1352 is disposed. Eight first pressing strips 1351 a are evenly disposed on the inner side of the frame 1351 , and four second pressing strips 1352 a are evenly disposed on the connecting strip 1352 .

[0041] In order to cope with the processing error, the eight first pressure strips 1351a are fixed to the inner side of the frame 1351 in an adjustable vertical position. For example, the first pressure strips 1351a can be provided with waist holes in the vertical direction, and fixed to the inner side of the frame 1351 through the waist holes and bolts. When the lifting and lowering plate 1350 is assembled, if the first pressure strips 1351a on all sides are not flush with the lower surface of the second pressure strips 1352a, the second pressure strips 1352a can be used as a reference to adjust the first pressure strips 1351a up and down to be flush with the lower surface of the second pressure strips 1352a.

[0042] In order to provide buffering when pressing the substrate, a buffer pad may be provided on the lower surface of each pressing strip, and the material of the buffer pad may be rubber or sponge, etc.

[0043] like Figure 4 As shown, the lifting plate 1350 is driven by the plate driving motor 1351 around it to achieve lifting, and the plate driving motor 1351 is fixed on the fixing frame 1360.

[0044] The laser marking station 1400 is used to perform laser marking on the substrate on the marking platform 1300 that moves to the marking position. It can determine the marking position of the substrate through the positioning camera thereon and then perform the marking.

[0045] The working process of the positive and negative coding machine of the utility model embodiment is as follows:

[0046] 1. The substrate is fed into the feed channel 1100 and transported horizontally from back to front in the feed channel 1100 intermittently. During the transportation process, the substrate information collection head 1110 collects the identity information of the substrate.

[0047] 2. Driven by the module 1500, the coding platform 1300 moves to the feed channel docking position and docks with the feed channel 1100, and receives the substrate from the feed channel 1100.

[0048] 3. After the substrate enters the coding platform 1300, it is stopped by the second stop mechanism 1320, and then the substrate is aligned by the alignment mechanism 1330. After that, the vacuum suction plate 1340 sucks the substrate and lifts it to the coding preparation position, and then the lifting and pressing plate 1350 presses the substrate downward.

[0049] 4. Driven by the module 1500, the coding platform 1300 moves to the coding position. The laser coding station 1400 determines the coding position of the substrate through the positioning camera thereon, and codes the substrate on the coding platform 1300 according to the identity information of the substrate. The dust collector 3 will lead out the dust removal pipe 31 to the bottom of the coding station 1400, and dust removal will be carried out synchronously during the coding process.

[0050] 5. After the coding is completed, the coding platform 1300 is driven by the module 1500 to move to the discharge channel docking position and dock with the discharge channel 1200 to deliver the coded substrate to the discharge channel 1200.

[0051] 6. The substrate first passes through the detection section of the discharge channel 1200, and the laser code quality detection head 1260 detects the quality of the laser code. After the detection is completed, it enters the substrate flipping section. Substrates with unqualified laser code quality are directly sent out through the substrate flipping section. For substrates with qualified laser code quality, if the back side has not been coded, they are flipped by the substrate flipping section and sent back to the coding platform 1300 through the detection section. The above 3-6 processes are repeated to achieve coding on the back side of the substrate. If the coding is completed on both the front and back sides of the substrate, the substrate is sent out by the substrate flipping section.

[0052] It can be seen from the above that the front and back coding machine provided by the embodiment of the utility model can automatically code the front and back sides of the substrate, thereby improving efficiency and reducing labor costs.

[0053] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
