[0035] Reference below Figures 1 to 6 The coding device of the present application is described in detail.

[0036] refer to Figure 1 According to the embodiment of the utility model, the coding device includes a coding module 100 and a transfer module 200; the coding module 100 includes a coding machine 120, and the transfer module 200 includes a slide rail 210, a first driver and a carrying fixture 220; the slide rail 210 is extended along the front-back direction, the carrying fixture 220 is slidably arranged on the slide rail 210, the output end of the first driver is connected to the carrying fixture 220, the coding machine 120 is located above the slide rail 210, and the coding area 101 of the coding machine 120 is directly below the coding machine 120. The rear end of the slide rail 210 is located in the coding area 101 of the coding machine 120, and the front end of the slide rail 210 forms a loading and unloading area 201.

[0037] When the coding device of this embodiment is working, the first driver can drive the carrier jig 220 to slide along the slide rail 210 to slide into the loading and unloading area 201, and then, the material box 600 fully loaded with workpieces can be loaded onto the carrier jig 220, and then, the first driver can drive the carrier jig 220 to slide along the slide rail 210 into the coding area 101, at this time, the coding machine 120 can code the workpieces in the coding area 101, and after all the workpieces in the material box 600 have been coded, the first driver can drive the carrier jig 220 to move to the loading and unloading area 201, at this time, the material box 600 fully loaded with coded workpieces on the carrier jig 220 can be unloaded, and the material box 600 fully loaded with uncoded workpieces can be loaded onto the carrier jig 220.

[0038] The workpiece may be a drill or a milling cutter.

[0039] It can be understood that in the coding device of the present embodiment, the workpieces can be loaded onto the carrier jig 220 in the form of a whole box, and can be coded in the form of a whole box, so that when the coding device of the present embodiment is working, a single loading and unloading can complete the coding of multiple workpieces. When the coding device of the present embodiment is working, the loading and unloading frequency of the workpieces is lower, which correspondingly improves the working efficiency of the coding device of the present embodiment.

[0040] It should be noted that the coding machine 120 includes a plurality of laser marking terminals, and the area directly facing the laser marking terminals is the coding area 101 of the coding machine 120. Figure 1 In the figure, the area directly facing the laser marking terminal of the coding machine 120 is the area directly below the coding machine 120 , and the rear end of the slide rail 210 is located directly below the coding machine 120 .

[0041] It should be noted that a plurality of workpieces are loaded in the material box 600 . Due to differences in the specifications of the workpieces themselves and the influence of the placement errors of the workpieces in the material box 600 , the heights of the workpieces in the material box 600 are different.

[0042] Based on the above situation, in order to enable the coding device of the present invention to successfully complete the coding of each workpiece in the material box 600, in some embodiments of the present invention, reference is made to Figure 1 The coding device also includes a first detection module 300, which is arranged on one side of the transfer module 200, and the slide rail 210 is partially located in the detection area of ​​the first detection module 300; the coding module 100 also includes a vertical driving structure 110, the coding machine 120 is connected to the driving end of the vertical driving structure 110, and the vertical driving structure 110 is electrically connected to the first detection module 300.

[0043] Furthermore, after the material box 600 is loaded onto the supporting fixture 220 in the loading and unloading area 201, driven by the first driver, the supporting fixture 220 can move along the slide rail 210 to the detection area of ​​the first detection module 300. At this time, the first detection module 300 can detect each workpiece in the material box 600 to obtain the height information of each workpiece, and transmit the height information to the vertical drive structure 110. Then, the first driver can drive the supporting fixture 220 to move along the slide rail 210 to the coding area 101. At this time, the vertical drive structure 110 can adjust the height of the coding machine 120 according to the height information of each workpiece, so that the coding machine 120 can successfully complete the coding of each workpiece.

[0044] Furthermore, in order to facilitate the first detection module 300 to detect the workpiece before coding, the detection area is arranged between the loading and unloading area 201 and the coding area 101 .

[0045] In a further embodiment of the present invention, reference Figure 1 The first detection module 300 includes a first mounting seat 310 and a first detector 320. The first detector 320 is slidably mounted on the first mounting seat 310 along the vertical direction. The area directly below the first detector 320 is the detection area of ​​the first detector 320. The slide rail 210 passes directly below the first detector 320.

[0046] Furthermore, the staff can adjust the height of the first detector 320 according to actual needs.

[0047] Specifically, the first mounting seat 310 includes a first mounting rod, a first mounting hole is provided on the first detector 320, the first mounting rod is passed through the first mounting hole, the hole wall of the first mounting hole is provided with a first adjustment seam connected to the outside world, and the first adjustment seam is connected to the two side walls in its width direction through a first threaded adjustment member.

[0048] Furthermore, when the staff needs to adjust the height of the first detector 320, the staff can expand the first adjustment gap through the first threaded adjustment piece, so that the staff can drive the first detector 320 to slide up and down along the first mounting rod to achieve the adjustment of the vertical position of the first detector 320; after the staff completes the vertical position adjustment of the first detector 320, the staff can reduce the width of the first adjustment gap by adjusting the first threaded adjustment piece, so that the hole wall of the first mounting hole can be close to and clamp the first mounting rod, thereby achieving the locking of the position of the first detector 320 on the first mounting rod.

[0049] In a specific embodiment of the present invention, the vertical drive structure 110 includes a vertically extending guide rail and a second driver, the coding machine 120 is slidably mounted on the guide rail, the second driver is connected to the coding machine 120, and can drive the coding machine 120 to move up and down along the guide rail.

[0050] It should be noted that when the carrying fixture 220 is in an unloaded state, the first driver does not need to drive the carrying fixture 220 to slide along the slide rail 210 .

[0051] Based on the above reasons, in some embodiments of the present invention, the coding device further includes a second detection module 400, and the second detection module 400 is electrically connected to the first driver.

[0052] Furthermore, the second detection module 400 can detect the carrier jig 220 to determine whether there is a material box 600 on the carrier jig 220. When the carrier jig 220 is in an unloaded state, the first driver does not operate to keep the carrier jig 220 in a stationary state. When the carrier jig 220 carries a material box 600, the first driver can drive the carrier jig 220 to move along the slide rail 210, so that the carrier jig 220 passes through the detection area of ​​the first detector 320 and the coding area 101 in sequence from the loading and unloading area 201.

[0053] In a specific embodiment of the present invention, reference Figure 1 The second detection module 400 includes a transmitter 410 and a receiver 420 , and the transmitter 410 and the receiver 420 are respectively arranged on both sides of the extending direction of the slide rail 210 .

[0054] Furthermore, when the carrier jig 220 is in an unloaded state, the receiver 420 can receive the detection light emitted by the transmitter 410. At this time, the second detection module 400 can determine that the carrier jig 220 is in an unloaded state; when the carrier jig 220 carries a material box 600, the material box 600 will block the detection light emitted by the transmitter 410, and the intensity of the detection light received by the receiver 420 is reduced. At this time, the second detection module 400 can determine that the carrier jig 220 carries a material box 600.

[0055] In order to enable the receiver 420 to accurately receive the detection light emitted by the generator, in a further embodiment of the present invention, the second detection module 400 also includes a second mounting bracket 430 and a third mounting bracket 440, the transmitter 410 is positionally adjustable on the second mounting bracket 430, and the receiver 420 is positionally adjustable on the third mounting bracket 440.

[0056] Specifically, refer to Figure 2The second mounting seat 430 includes a second mounting rod 431, a third mounting rod 432 and a fourth mounting rod 433. The second mounting rod 431 is provided with a second mounting hole and a third mounting hole at opposite ends thereof, respectively. The second mounting hole extends in a vertical direction, and the third mounting hole extends in a horizontal direction. The third mounting rod 432 is slidably inserted into the second mounting hole, and the fourth mounting rod 433 is slidably inserted into the third mounting hole. A second adjustment slit 431a is provided on the hole wall of the second mounting hole, and the second adjustment slit 431a is connected at both ends in its width direction by a second threaded adjustment member. A third adjustment slit 431b is provided on the hole wall of the third mounting hole, and the third adjustment slit 431b is connected at both ends in its width direction by a third threaded adjustment member. The transmitter 410 is slidably sleeved on the fourth mounting rod 433 along the extension direction of the fourth mounting rod 433.

[0057] Specifically, the specific structure of the third mounting seat 440 refers to the second mounting seat 430 .

[0058] It should be noted that when the coding machine 120 codes the workpiece, harmful gases will be generated, and these harmful gases will affect the health of the workers.

[0059] In order to timely remove the harmful gases generated by the coding machine 120 when it is working, in some embodiments of the present utility model, reference Figure 1 The coding device also includes a purification module 500, which is arranged on one side of the coding area 101. The purification module 500 includes an air suction nozzle 510 and an air extractor 520. The air suction nozzle 510 includes a connected air suction port and a connecting port. The air suction port faces the coding area 101, and the connecting port is connected to the air extractor 520.

[0060] Furthermore, when the coding machine 120 is coding the workpiece, the vacuum machine 520 can extract harmful gases in the coding area 101 through the suction nozzle 510 .

[0061] In order to facilitate the adjustment of the posture of the air suction nozzle 510, in a further embodiment of the present invention, the purification module 500 also includes a mounting frame 530, and the air suction nozzle 510 is mounted on the mounting frame 530 and can be rotatably arranged, and the connecting port is connected to the vacuum fan 520 through a hose.

[0062] Furthermore, the staff can adjust the direction of the air intake port by rotating the air intake nozzle 510 so that the air intake port can face the coding area 101.

[0063] Specifically, refer to Figure 3The mounting frame 530 includes a mounting piece 531 and a clamp 532. The clamp 532 is sleeved on the suction nozzle 510, and a connecting portion 532a is provided on the clamp 532. A horizontally extending through hole is provided on the mounting piece 531. The connecting portion 532a is rotatably inserted into the through hole. A slit 531a communicating with the outside is provided on the hole wall of the through hole, and the two side walls of the slit 531a in the width direction are connected by a threaded adjustment structure.

[0064] Furthermore, when the staff needs to rotate the suction nozzle 510, the staff can increase the width of the gap 531a through the threaded adjustment structure. At this time, the connecting portion 532a can rotate relative to the hole wall of the through hole, and the staff can drive the suction nozzle 510 to rotate relative to the mounting member 531. After the staff completes the rotation of the suction nozzle 510, the staff can reduce the width of the gap 531a through the threaded adjustment structure. At this time, the hole wall of the through hole can fit and lock the connecting portion 532a, thereby achieving locking and fixation of the suction nozzle 510.

[0065] Specifically, the thread adjustment structure includes a bolt and a nut, the bolt thread is penetrated through the two side walls of the gap 531a in its width direction, the nut thread is connected to the bolt, and the nuts of the nut and the bolt are respectively located on both sides of the gap 531a in its width direction.

[0066] When the material box 600 is carried on the carrying jig 220 , in order to make the position of the material box 600 on the carrying jig 220 relatively fixed, in some embodiments of the present invention, a positioning structure is provided on the carrying jig 220 .

[0067] It is understandable that when the material box 600 is placed on the carrier jig 220, the positioning structure can position the material box 600 on the carrier jig 220 so that the material box 600 can be in a relatively fixed position on the carrier jig 220, so that the subsequent coding machine 120 can code the workpiece on the material box 600.

[0068] In a specific embodiment of the present invention, reference Figure 4 The supporting fixture 220 is provided with a receiving groove for receiving the material box 600, and the positioning structure includes a positioning plate 221 and an elastic connecting member (not shown in the figure). The positioning plate 221 can be movably arranged in the receiving groove, and the front and rear ends of the elastic connecting member are respectively connected to the positioning plate 221 and the groove wall of the receiving groove.

[0069] Furthermore, when the material box 600 is placed in the receiving groove, under the elastic force of the elastic connector, the positioning plate 221 can approach and squeeze the material box 600. At this time, the positioning plate 221 can cooperate with the groove wall of the receiving groove to clamp and fix the material box 600, thereby realizing the positioning of the material box 600.

[0070] Optionally, in other embodiments of the present invention, the positioning structure may also include multiple groups of corresponding positioning plates 221 and elastic connectors. In this case, multiple positioning plates 221 can be slidably disposed in the accommodating groove, and multiple positioning plates 221 are surrounded to form a positioning area, and the opposite ends of the elastic connector are respectively connected to the positioning plates 221 and the groove walls of the accommodating groove; when the material box 600 is placed in the positioning area, under the elastic force of the elastic connector, each positioning plate 221 can cooperate with each other to complete the clamping positioning of the material box 600 in the positioning area.

[0071] In a further embodiment of the present invention, in order to facilitate the limitation of the sliding stroke of the positioning plate 221, refer to Figure 5 and Figure 6 The positioning structure also includes a limiting member 222, which includes an abutting section 222a and a connecting section 222b. The connecting section 222b is penetrated through the groove wall of the accommodating groove and is connected to the positioning plate 221. The abutting section 222a is located outside the groove of the accommodating groove and is used to abut against the outer wall of the groove of the accommodating groove.

[0072] Furthermore, under the elastic force of the elastic connector, the positioning plate 221 can slide in the accommodating groove until the abutment section 222a abuts against the outer wall of the accommodating groove. At this time, the positioning plate 221 cannot continue to slide under the elastic force of the elastic connector, thereby limiting the travel of the positioning plate 221.

[0073] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
