After the partial pattern winding tape 200 of examining after unreeling passes through detection region 30a, two first grip rollers and two second grip rollers 421 butt respectively in two upper and lower surfaces of the partial pattern winding tape 200 of examining, so can fix the exhibition flat with the both ends of pattern winding tape 200 to avoid the pattern winding tape 200 in detection region 30a to take place the condition of distortion. The utility model provides a simple structure of first holder and second holder 42 to it is fixed with pattern winding 200's both ends in the detection area 30a through two first grip rollers and two second grip rollers 421, not only the flat effect of exhibition is better, moreover after detecting, along with the rotation of two first grip rollers and two second grip rollers 421, can pull pattern winding 200 simultaneously and unreel, continue to detect next pattern, thereby improve the detection efficiency of pattern.

Further, in the present application, the flattening mechanism 40 further includes a driving assembly (not shown) disposed on the frame 10 and in transmission connection with the two first grip rollers and the two second grip rollers 421. The driving assembly drives the two first pinch rollers and the two second pinch rollers 421 to rotate, so as to pull the patterned tape 200 to unreel along the feeding direction.

Specifically, the driving assembly includes a driving member 43, a first transmission member, a second transmission member 44, and a link member 46. Wherein, this driving piece 43 includes driving motor 431, capstan 432, follower 433 and driving belt, and driving motor 431 can be step motor or servo motor, prefers step motor in this application. The output shaft of driving motor 431 is located to the action wheel 432 cover, locates the tip that is located the second pinch roll 421 of uppermost end from the driving wheel 433 cover, and action wheel 432 and follow driving wheel 433 are located to the transmission belt cover. The first transmission member includes two first transmission gears, the two first transmission gears are respectively sleeved on the end portions of the two first clamping rollers and are meshed with each other, the second transmission member 44 includes two second transmission gears 441, and the two second transmission gears 441 are respectively sleeved on the end portions of the two second clamping rollers 421 and are meshed with each other. The linkage 46 includes two synchronizing wheels 461 and a timing belt 462, the two synchronizing wheels 461 are respectively sleeved on the ends of the second holding roller 421 and the first holding roller at the lower end, and the timing belt 462 is sleeved on the two synchronizing wheels 461.

In this application, after the pattern detection in the detection area 30a is finished by the detection camera 31, the driving motor 431 rotates and drives the second holding roller 421 located at the upper end to rotate, the second holding roller 421 at the upper end drives the second holding roller 421 at the lower end to rotate through the two second transmission gears 441, the second holding roller 421 at the lower end drives the first holding roller at the lower end to rotate through the synchronizing wheel 461 and the synchronous belt 462, and the first holding roller at the lower end rotates and drives the first holding roller at the upper end to rotate through the two first transmission gears. After driving motor 431 rotates promptly, two first pinch rolls and two second pinch rolls 421 synchronous rotation unreel the picture tape 200 along the pay-off direction, after waiting to unreel certain length, make next pattern be located detection area 30a, driving motor 431 stall, detect by detecting camera 31 again, so reciprocal, in this application, can realize adopting two first pinch rolls of single driving motor 431 drive and two synchronous pivoted effects of second pinch roll 421 through setting up first driving piece, second driving piece 44 and linkage 46, the drive assembly structure is comparatively simple. Moreover, since the two first grip rollers and the two second grip rollers 421 rotate in two steps, that is, there is no speed difference between the two first grip rollers and the two second grip rollers, in the process of continuously unwinding the pattern tape 200, the situation that the pattern is deformed due to the fact that the pattern tape 200 in the detection area 30a is too tight or too loose at the two ends of the pattern tape 200 due to the speed difference can also be avoided, so that the accuracy of pattern detection is further improved.

The driving assembly further includes a sensor 47, the sensor 47 is disposed on the frame 10 and is in communication connection with the driving motor 431 through a wire or a wireless transceiver module, and the sensor 47 corresponds to the pattern tape 200 for sensing the position of the pattern on the pattern tape 200. In one embodiment, after the inspection camera 31 finishes inspecting the patterns in the inspection area 30a, the inspection camera 31 sends the signal to a controller (not shown), the controller controls the driving motor 431 to rotate, the sensor 47 senses that the pattern tape 200 is unwound by a certain distance or a distance per unit of pattern, the sensor 47 sends the signal to the controller, and the controller controls the driving motor 431 to stop rotating, and so on. Meanwhile, in the present application, the trademark detection machine 100 further includes a display 50, the display 50 is in communication connection with the controller for displaying the result of detecting the pattern, so that the user can more intuitively see the defective product, thereby facilitating the detection of the pattern to a greater extent.

Referring to fig. 2 and fig. 4 again, since the widths of the different patterned tapes 200 are different, in an embodiment of the present invention, the feeding tray 22 includes a fixed tray body 221 and a movable tray body 222, wherein the fixed tray body 221 and the movable tray body 222 are spaced and sleeved on the installation shaft 21, the fixed tray body 221 is in a relatively static state with respect to the installation shaft 21 in the extending direction of the installation shaft 21, and the movable tray body 222 is sleeved on the installation shaft 21 and can slide close to or away from the fixed tray body 221 under the action of an external force. That is, the distance between the fixed trays 221 is varied so that the feed tray 22 can restrain the pattern tape 200 of different widths on the mounting shaft 21, and thus the compatibility of the brand detection machine 100 is better.

Further, the feeding tray 22 further includes an adjusting spring 223, the end of the mounting shaft 21 is provided with a stop block 23, and the adjusting spring 223 is sleeved on the mounting shaft 21 and elastically abuts against the movable tray 222 and the stop block 23. When the pattern tape 200 is placed between the movable disk 222 and the fixed disk 221, the elastic force of the adjusting spring 223 has a tendency of pushing the movable disk 222 against one side of the fixed disk 221, so that the movable disk 222 and the fixed disk 221 are clamped on opposite sides of the pattern tape 200, and thus, when replacing pattern tapes 200 with different widths, a user does not need to adjust the distance between the movable disk 222 and the fixed disk 221 again, and can firmly fix the pattern tape 200, the compatibility of the trademark detection machine 100 is better, and the operation efficiency of disassembling and assembling the pattern tape 200 is higher.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
