Abstract
Description
Technical Field
[0001] This application belongs to the field of sensor manufacturing technology, specifically a photoelectric sensor receiver housing. Background Technology
[0002] The receiver of a photoelectric sensor contains a CMOS sensor and a circuit board. The CMOS sensor needs to be electrically connected to the circuit board to process the light signal it senses. To enable the CMOS sensor to detect the light signal, the receiver also contains many optical components, such as convex lenses and plane mirrors, to change the direction of light propagation. This results in a large variety and number of components inside the photoelectric sensor receiver. During repair, while the optical components are hardware with long lifespans and are not easily damaged, the circuit board is prone to failure. Therefore, the circuit board often needs to be replaced. Because the components are closely interconnected, opening the receiver housing to replace the circuit board can easily damage other optical components, altering their relative positions. This requires readjusting the relative positions of the optical components, increasing repair time and reducing efficiency. Utility Model Content
[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a photoelectric sensor receiver housing that uses a main housing and a sub-housing to cooperate with each other. This allows optical components to be installed inside the sub-housing, while the circuit board is installed in the main housing in an area outside the sub-housing. This ensures that the optical components are not affected when the circuit board is repaired or replaced, thereby saving repair time.
[0004] To achieve the above objectives, the technical solution adopted in this application is:
[0005] A photoelectric sensor receiver housing includes a main housing, a secondary housing, and a cover that mates with the main housing. The main housing is composed of a main bottom wall and a main side wall, and the secondary housing is composed of a secondary side wall and a secondary bottom wall. The height of the main side wall is greater than or equal to the height of the secondary side wall. The main side wall has a first opening, and the secondary side wall has a second opening. One end of the main housing has a secondary housing mounting area for upside-down mounting of the secondary housing. When the secondary housing is mounted in the secondary housing mounting area, the first opening and the second opening are coaxial. The secondary side wall has a first through hole facing the side of the main housing that is not in the secondary housing mounting area. The main side wall has a second through hole and a heat dissipation hole at the end away from the secondary housing mounting area. The cover covers the side of the main housing facing away from the main bottom wall. The main housing, secondary housing, and cover are all made of opaque material.
[0006] Preferably, a plane mirror mounter is provided on the secondary sidewall facing away from the second opening inside the secondary housing, and a convex lens mounter is provided on the secondary sidewall at the second opening.
[0007] Preferably, the main bottom wall is provided with a threaded blind hole inside the main housing, and the sub-housing is provided with a connecting lug parallel to the sub-bottom wall on the sub-side wall, and the connecting lug is provided with a through hole that mates with the threaded blind hole.
[0008] Preferably, the main bottom wall has a groove perpendicular to the main housing inside the main housing, and the secondary side wall has a protrusion that mates with the groove outside the secondary housing.
[0009] Preferably, the sub-bottom wall has two glue injection holes near the location of the first through hole, and there is a preset gap between the two glue injection holes.
[0010] Preferably, the projection of the first through hole onto the connecting line segment between the two glue injection holes is located between the two ends of the connecting line segment between the two glue injection holes.
[0011] Preferably, the shape and size of the second opening are smaller than the shape and size of the first opening.
[0012] Preferably, the convex lens mounter includes two first slots, the projections of the two first slots on the sub-bottom wall are U-shaped, the U-shaped openings of the two first slots are arranged facing each other, the connecting line segment between the projections of the two first slots on the sub-bottom wall is perpendicular to the axis of the second opening, and the projections of the two first slots on the sub-bottom wall are located on both sides of the projection of the axis of the second opening on the sub-bottom wall.
[0013] Preferably, the plane mirror mounter includes two second slots, the projections of the two second slots on the sub-bottom wall are U-shaped, the U-shaped openings of the two second slots are arranged facing each other, and the angle formed between the axis of the second opening and the projection of the connecting line segment between the two second slots on the sub-bottom wall is angle A; the angle formed between the axis of the first through hole and the projection of the connecting line segment between the two second slots on the sub-bottom wall is angle B, and the degree measures of angle A and angle B are equal.
[0014] Compared with the prior art, this application has the following beneficial effects:
[0015] 1. This application adopts a main housing and a sub-housing to cooperate with each other to design a photoelectric sensor receiver housing, which allows optical components to be installed in the sub-housing, while the circuit board is installed in the main housing in an area outside the sub-housing. This ensures that the optical components are not affected when the circuit board is repaired or replaced, thereby saving repair time.
[0016] 2. The threaded blind hole in this application is designed to mate with the through hole, so that after the sub-shell is installed on the main shell, a screw is screwed through the through hole into the threaded blind hole to fix the sub-shell inside the main shell. This prevents the optical components inside the sub-shell from being touched after the cover is opened.
[0017] 3. With the addition of two injection holes, the CMOS sensor can be fixed to the mounting plate first, and then the mounting plate can be fixed to the inside of the sub-side wall. Glue can then be injected through the injection holes from outside the sub-housing to fix the mounting plate to the sub-side wall. This avoids glue sticking to the photosensitive area of the CMOS sensor during glue application. Attached Figure Description

Detailed Implementation
[0025] like Figure 1-6 As shown, a photoelectric sensor receiver housing includes a main housing 1, a secondary housing 2, and a cover 3 that mates with the main housing 1. The main housing 1 is composed of a main bottom wall 1-1 and a main side wall 1-2. The secondary housing 2 is composed of a secondary side wall 2-2 and a secondary bottom wall 2-1. The height of the main side wall 1-2 is greater than or equal to the height of the secondary side wall 2-2. The main side wall 1-2 has a first opening 4, and the secondary side wall 2-2 has a second opening 5. One end of the main housing 1 has a cover for upside-down mounting of the sensor receiver. The sub-shell 2 has a sub-shell mounting area; when the sub-shell 2 is installed in the sub-shell mounting area, the first opening 4 and the second opening 5 are coaxial, the sub-side wall 2-2 is provided with a first through hole 6 facing the side of the main shell 1 that is not in the sub-shell mounting area, the main side wall 1-2 is provided with a second through hole 7 and a heat dissipation hole 8 at one end away from the sub-shell mounting area, and the cover 3 covers the side of the main shell 1 that faces away from the main bottom wall 1-1. The main shell 1, the sub-shell 2, and the cover 3 are all made of opaque material.
[0026] In this embodiment, the main bottom wall 1-1 and the main side wall 1-2 constitute the main shell 1, and the secondary side wall 2-2 and the secondary bottom wall 2-1 constitute the secondary shell 2. Since the height of the main side wall 1-2 is greater than or equal to the height of the secondary side wall 2-2, when the secondary shell 2 is upside down in the secondary shell mounting area inside the main shell 1, the secondary shell 2 can be completely located inside the main shell 1, and the cover 2 can completely wrap the secondary shell 2 inside the main shell 1 when it is closed on the main shell 1, so that the secondary shell 2 and the main shell 1 become a whole.
[0027] And after the secondary housing 2 is installed in the main housing 1:
[0028] The first opening 4 and the second opening 5 are coaxial, allowing light to pass through the first opening 4 and the second opening 5 before entering the sub-shell 2. Then, the convex lens 21 and the plane mirror 22 can be installed inside the sub-shell 2, while the circuit board is installed inside the main shell 1 at the portion outside the sub-shell 2. Figure 1 The CMOS sensor 23 is mounted on the secondary sidewall 2-2 inside the secondary housing 2 (lower half of the main housing 1). The connector 19 of the CMOS sensor 23 is then passed through the first through-hole 6 into the portion of the main housing 1 located outside the secondary housing 2. The end of the connector 19 facing away from the CMOS sensor 23 is then electrically connected to the circuit board. The second through-hole 7 is provided to allow external wiring of the circuit board to pass through to the outside of the main housing 1 for connection to external devices. Since the circuit board easily generates heat during operation, heat dissipation holes 8 are provided.
[0029] With this setup, during maintenance, after opening the cover 3, the optical components (plane mirror 22 and convex lens 21) will not be touched without opening the sub-shell 2. Therefore, during maintenance, it is not necessary to calibrate the relative positional relationship between the plane mirror 22, convex lens 21, and CMOS sensor 23.
[0030] As a preferred embodiment, a plane mirror mounter is provided on the secondary sidewall 2-2 facing away from the second opening 5 inside the secondary housing 2, and a convex lens mounter is provided on the secondary sidewall 2-2 at the second opening. Thus, the plane mirror 22 is mounted by providing the plane mirror mounter, and the convex lens 21 is mounted by providing the convex lens mounter.
[0031] As a preferred embodiment, the main bottom wall 1-1 has a threaded blind hole 9 inside the main housing 1, and the sub-housing 2 has a connecting lug 10 parallel to the sub-bottom wall 2-1 on the sub-side wall 2-2. The connecting lug 10 has a through hole 11 that mates with the threaded blind hole 9. This threaded blind hole 9 is designed to mate with the through hole 11, so that after the sub-housing 2 is installed on the main housing 1, a screw is screwed through the through hole 11 into the threaded blind hole 9, thereby fixing the sub-housing 2 inside the main housing 1. This prevents the optical components inside the sub-housing 2 from being touched after the cover 3 is opened.
[0032] As a preferred embodiment, the main bottom wall 1-1 has a slot 12 perpendicular to the main housing 1, and the secondary side wall 2-2 has a protrusion 13 that mates with the slot 12 on the outside of the secondary housing 2. The slot 12 and protrusion 13 are thus used for positioning during assembly, facilitating the installation of the secondary housing 2 into a designated position within the main housing 1.
[0033] As a preferred embodiment, the sub-bottom wall 2-1 is provided with two glue injection holes 14 near the location of the first through hole 6, with a preset gap between the two glue injection holes 14. This arrangement of two glue injection holes 14 allows for the following manufacturing process: the CMOS sensor 23 can be fixed to the fixing plate 20 first, and then the fixing plate 20 can be fixed to the inner side of the sub-side wall 2-2. Glue can then be injected from outside the sub-shell 2 through the glue injection holes 14 to fix the fixing plate 20 to the sub-side wall 2-2. This avoids glue sticking to the photosensitive area of the CMOS sensor 23 during glue application.
[0034] As a preferred embodiment, the projection of the first through hole 6 onto the connecting line segment between the two glue injection holes 14 is located between the two ends of the connecting line segment between the two glue injection holes 14. This arrangement ensures that the glue injection holes 14 are completely offset from the CMOS sensor 23, thereby preventing glue from sticking to the photosensitive area of the CMOS sensor 23 during glue application.
[0035] As a preferred embodiment, the second opening 5 is smaller in shape and size than the first opening 4. This arrangement ensures that the light entering the first opening 4 can fully illuminate the plane mirror 22 and the convex lens 21 installed inside the sub-housing 2, thereby preventing the plane mirror 22 and the convex lens 21 from not receiving light.
[0036] As a preferred embodiment, the convex lens mount includes two first slots 15. The projections of the two first slots 15 onto the sub-bottom wall 2-1 are U-shaped, with the U-shaped openings of the two first slots 15 facing each other. The connecting line segment between the projections of the two first slots 15 onto the sub-bottom wall 2-1 is perpendicular to the axis of the second opening 5. The projections of the two first slots 15 onto the sub-bottom wall 2-1 are located on either side of the projection of the axis of the second opening 5 onto the sub-bottom wall 2-1. This arrangement facilitates assembly; during assembly, both ends of the convex lens 21 can be directly inserted into the two first slots 15 respectively.
[0037] In a preferred embodiment, the plane mirror mounter includes two second slots 16, the projections of the two second slots 16 onto the sub-bottom wall 2-1 being U-shaped, with the U-shaped openings of the two second slots 16 facing each other. The angle formed between the axis of the second opening 5 and the projection of the connecting line segment between the two second slots 16 onto the sub-bottom wall 2-1 is angle A17; the angle formed between the axis of the first through hole 6 and the projection of the connecting line segment between the two second slots 16 onto the sub-bottom wall 2-1 is angle B18, and the degrees of angles A17 and B18 are equal (e.g., ...). Figure 6 (As shown). This configuration facilitates assembly; during assembly, the two ends of the plane 22 can be directly inserted into the two second slots 16. The angle B18 formed between the axis of the first through hole 6 and the projection of the connecting line segment between the two second slots 16 onto the sub-bottom wall 2-1 ensures that light entering the second opening 5 and parallel to its axis can be reflected onto the CMOS sensor 23 mounted at the first through hole 6.
