Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and specifically discloses an outer diameter testing device. Background Technology

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing onto relevant media. The printer roller is installed inside the printer and is used to hold the wristband roll or other printing paper roll, or to assist in the paper feeding of roll paper or other printing materials. It is an important structure for the printer to print. During the production process of the printer roller, it is necessary to test the outer diameter of the produced printer roller.

[0003] The existing method for detecting the outer diameter of printer rollers involves operators using a dial indicator, which has a large error, is time-consuming and labor-intensive, and has low work efficiency. Therefore, this application discloses an outer diameter detection device. Utility Model Content

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] Example

[0025] To address the problems associated with manually measuring the outer diameter of printer rollers using a dial indicator in existing technologies, reference was made to... Figures 1-4 As shown, this application discloses an outer diameter detection device, including a detection conveying mechanism 10, an outer diameter detection mechanism 20, and a non-conforming product unloading and recycling mechanism 30; the detection conveying mechanism 10 includes two parallel chain conveyor lines 11 and several placement fixtures 12 separately arranged on the two chain conveyor lines 11; in specific operation, the operator places the printer roller to be detected onto the corresponding placement fixtures 12 on the two chain conveyor lines 11 in sequence, and the two chain conveyor lines 11 move the placement fixtures 12 forward.

[0026] The outer diameter detection mechanism 20 includes a rotating tip unit 21 positioned above the middle of the two chain conveyor lines 11, an upper longitudinal drive unit 22 positioned above the middle of the two chain conveyor lines 11, a lower longitudinal drive unit 23 positioned below the middle of the two chain conveyor lines 11, a laser emitter 24 connected to the upper longitudinal drive unit 22, and a laser receiver 25 connected to the lower longitudinal drive unit 23. When the printer roller reaches the middle position of the two chain conveyor lines 11, the rotating tip unit 21 clamps the printer roller and drives it to rotate. Then, the upper longitudinal drive unit 22 and the lower longitudinal drive unit 23 drive the laser emitter 24 and the laser receiver 25 to move longitudinally, respectively. During this process, the laser emitter 24 emits a laser beam. As long as the printer roller blocks the beam, the laser receiver 25 will generate a signal and send it to an external processing system (known technology, not described in detail here) to obtain the corresponding outer diameter value.

[0027] The defective product unloading and recycling mechanism includes two transverse drive units 31 located in the middle to rear sections of the two chain conveyor lines 11, an automatic conveying unit 32 connected to the two transverse drive units 31, and a belt conveyor line 33 erected above the rear section of the two chain conveyor lines 11. If the printer roller shaft is detected as a qualified product, the automatic conveying unit 32 and the belt conveyor line 33 will stop operating. Conversely, if the printer roller shaft is detected as a defective product, the automatic conveying unit 32 will automatically transport the defective printer roller shaft to the belt conveyor line 33 for unloading.

[0028] In addition, it should be noted that the automatic conveying unit 32 of this application performs the material grabbing action when the printer roller axis moves backward a certain distance. In this way, unnecessary interference with the outer diameter detection mechanism 20 can be avoided.

[0029] Furthermore, each of the two chain conveyor lines 11 and belt conveyor lines 33 of this application is provided with a collection box at the end of its conveying process, one for collecting qualified products and the other for collecting unqualified products.

[0030] In one specific embodiment, the mounting fixture 12 of this application includes a fixture block, and a U-shaped groove 121 is provided on the vertical part of the fixture block. A layer of MC-cast nylon A is provided on the inner wall of the U-shaped groove 121. In actual use, the printer roller shaft to be tested is placed between the two U-shaped grooves 121 of the two fixture blocks, and the roller cores at both ends are exposed from the U-shaped grooves 121. In addition, by providing MC-cast nylon A in the U-shaped grooves 121, this application can avoid large friction of the printer roller shaft when it rotates, thus playing a role in protecting the printer roller shaft.

[0031] In order to install the upper longitudinal drive unit 22 of this application, a first gantry 40 is provided above the middle section of the two chain conveyor lines 11, and the upper longitudinal drive unit 22 is located at the bottom of the crossbeam of the first gantry 40.

[0032] This embodiment is an exemplary embodiment of this application. Specifically, this application may use an electric slide table for the upper longitudinal drive unit 22, the lower longitudinal drive unit 23 and the two transverse drive units 31. In addition to the electric slide table, those skilled in the art may also use a rodless cylinder to replace the electric slide table in specific implementations. As for other alternatives, this application will not elaborate on them here.

[0033] In one specific embodiment, the rotating tip unit 21 of this application includes a first pneumatic slide 211 respectively disposed on two chain conveyor lines 11, an active rotating shaft seat 212 respectively disposed on the two first pneumatic slides 211, a passive rotating shaft seat 213 respectively disposed on the two first pneumatic slides 211, and tip bodies 214 respectively connected to the opposite side of the active rotating shaft seat 212 and the passive rotating shaft seat 213. When the two belt conveyor lines 33 drive the printer roller shaft to move to the middle position, the two first pneumatic slides 211 will drive the active rotating shaft seat 212 and the passive rotating shaft seat 213 to move closer to each other until the two tip bodies 214 press against the roller core of the printer roller shaft. When the printer roller shaft is detected, the printer roller shaft can be rotated as a whole by controlling the rotating shaft seat to drive the tip body 214 connected to it to rotate.

[0034] In one specific embodiment, the automatic handling unit 32 of this application includes a second gantry 321 connected to two transverse drive units 31, two second pneumatic slides 32 respectively disposed on both sides of the crossbeam of the second gantry 321, and two pneumatic clamps 323 respectively disposed on the second pneumatic slides 32. When the outer diameter detection mechanism 20 detects that the printer roller shaft is a defective product, the two transverse drive units 31 drive the second gantry 321 to move to the rear position of the outer diameter detection mechanism 20. After reaching the position, the two second pneumatic slides 32 will respectively drive the two pneumatic clamps 323 to descend, and... After the two pneumatic clamps 323 descend into position, they will clamp the roller core from both ends of the printer roller shaft (after this action is completed, the second pneumatic slide 32 drives the two pneumatic clamps 323 to reset). Then, the two transverse drive units 31 drive the second gantry 321 to move above the belt conveyor 33, and the two second pneumatic slides 32 will drive the two pneumatic clamps 323 to descend. When the two pneumatic clamps 323 release the printer roller shaft, the printer roller shaft will be placed on the belt conveyor 33 (after this action is completed, the second pneumatic slide 32 drives the two pneumatic clamps 323 to reset).

[0035] Based on the above embodiments, in order to better clamp the printer roller shaft, this application provides arc-shaped grooves 3231 on the clamping surfaces of the two jaws included in the pneumatic clamp 323. A layer of MC-cast nylon A is formed in the arc-shaped groove 3231. The function of the MC-cast nylon A is the same as that of the MC-cast nylon A mentioned on the inner wall of the U-shaped groove 121, which can play a wear-resistant role.
