Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, and in particular to a printer component anti-reverse installation detection device. Background Technology

[0002] Printer housings are typically made of plastic. To facilitate subsequent assembly, printer housings usually come pre-assembled with some components. Due to the large number of connection points on the printer housing, incorrect assembly of components is a common problem.

[0003] Due to the irregular shape of the printer housing and the inconvenience of fixture positioning, when parts are misinstalled or installed backwards, the printer housing can only be inspected manually, resulting in low inspection efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a printer component anti-reverse installation detection device to solve the problem of low detection efficiency when parts are incorrectly or reversed on existing printer components.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a printer component anti-reverse installation detection device, comprising:

[0006] A support base is provided with a first positioning block and a second positioning block. The height of the first positioning block is greater than the height of the second positioning block. A position sensor is provided inside the first positioning block. The printer component is placed on the support base.

[0007] A photoelectric sensor is located on one side of the support base, facing the pre-assembled parts on the printer component;

[0008] A cable connector is used to position the cable of a position sensor.

[0009] As a further description of the above technical solution:

[0010] The surface of the support is provided with a first rubber pad layer.

[0011] As a further description of the above technical solution:

[0012] The wire seat is located between the first positioning block and the second positioning block, and the wire seat is provided with a slot for positioning the position sensor cable.

[0013] As a further description of the above technical solution:

[0014] The wire connector is detachably mounted on the support.

[0015] As a further description of the above technical solution:

[0016] A first guide slope is provided on the top surface of the first positioning block.

[0017] As a further description of the above technical solution:

[0018] A second rubber pad layer is provided on the inner wall of the second positioning block.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, after the printer component is pre-assembled and before entering the next assembly step, in order to check whether the parts are installed backwards or incorrectly, the printer component is placed on the support base, and the four corners of the printer component are positioned by the first positioning block and the second positioning block. The position sensor is set inside the first positioning block, which not only realizes the detection of the bent and raised end of the printer component, but also supports the printer component and effectively detects that the printer component is placed in place. At the same time, the photoelectric sensor detects the parts. If the parts are installed backwards or incorrectly, they will not be detected by the photoelectric sensor, thus quickly realizing the detection of incorrect or reversed parts on the printer component, ensuring detection quality and efficiency.

[0021] 2. In this utility model, the wire seat is disposed between the first positioning block and the second positioning block, and the wire seat is provided with a slot for positioning the position sensor cable. The position sensor cable is led out from the gap between the lower part of the printer component's bent and raised end and the support base, and is positioned by being snapped into the slot of the wire seat, effectively preventing the position sensor cable from affecting the stable placement of the printer component.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1-4 This utility model provides a technical solution: a printer component anti-reverse installation detection device, comprising:

[0032] The support 1 is provided with a first positioning block 11 and a second positioning block 12. The height of the first positioning block 11 is greater than the height of the second positioning block 12. A position sensor 13 is provided inside the first positioning block 11. The position sensor 13 is a photoelectric sensor. The printer component 9 is placed on the support 1.

[0033] Photoelectric sensor 2 is disposed on one side of support 1, and photoelectric sensor 2 faces the pre-assembled part 91 on printer component 9;

[0034] The cable connector 3 is used to position the cable of the position sensor 13.

[0035] The support 1 has a first rubber pad 14 on its surface, which effectively prevents the printer component 9 from colliding and being damaged by the support 1 during testing.

[0036] The top surface of the first positioning block 11 is provided with a first guide slope 111 to prevent the printer component 9 from colliding and being damaged when placed on the surface of the support 1, and to facilitate the placement of the printer component 9. The top of the second positioning block 12 is similarly provided with a guide slope.

[0037] Working principle: After the pre-assembled parts 91 are assembled and before the next assembly step, in order to check whether parts 91 are installed backwards or incorrectly, the printer component 9 is placed on the support 1, and the four corners of the printer component 9 are positioned by the first positioning block 11 and the second positioning block 12. The position sensor 13 is set inside the first positioning block 11, which not only realizes the detection of the bent and raised end of the printer component 9, but also supports the printer component 9 and effectively detects that the printer component 9 is placed in place. At the same time, the photoelectric sensor 2 detects the parts 91. If the parts 91 are installed backwards or incorrectly, they will not be detected by the photoelectric sensor 2. This quickly realizes the detection of incorrect or reversed parts on the printer component, ensuring detection quality and efficiency.

[0038] Example 2

[0039] This embodiment further improves upon the above embodiment by providing the following technical solution: The wire guide 3 is positioned between the first positioning block 11 and the second positioning block 12, and the wire guide 3 has a slot 31 for positioning the cable of the position sensor 13. The cable of the position sensor 13 is led out from the gap between the lower bent end of the printer component 9 and the support 1, and is positioned by being snapped into the slot 31 of the wire guide 3, effectively preventing the cable of the position sensor 13 from affecting the stable placement of the printer component 9.

[0040] Example 3

[0041] Based on the above embodiments, this embodiment further improves upon the following technical solution: the wire seat 3 is detachably mounted on the support seat 1.

[0042] The wire connector 3 can be installed on the support 1 by plugging or bolting, which allows for detachable installation and easy adjustment of the installation position.

[0043] Example 4

[0044] Based on the above embodiments, this embodiment further improves upon the following technical solution: a second rubber pad 121 is provided on the inner side wall of the second positioning block 12 to further prevent collision damage between the side end face of the printer component 9 and the second positioning block 12.

[0045] Similarly, a rubber pad layer is provided on the inner wall of the first positioning block 11.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
