[0034] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0035] like Figure 1 - Figure 5 As shown, the sensor module debugging fixture provided by the present invention is used to install and debug the sensor module to be debugged, and can position each photoelectric sensor 3 on the outer side of the rotating claw 1 thereon.

[0036] Specifically, the sensor module is provided with a rotating claw 1 that can rotate around a vertical axis, and a photosensitive film is provided on the circumferential outer wall of the rotating claw 1. A slide groove 2 extending in the horizontal direction is provided on the circumferential outer side of the rotating claw 1, and a photoelectric sensor 3 whose position is to be adjusted is provided in the slide groove 2, and the slide groove 2 is spaced apart from the rotating claw 1. Among them, for a rotating claw 1, the number of slide grooves 2 and photoelectric sensors 3 on its circumference is at least two, and they correspond one to one, and two adjacent slide grooves 2 are arranged vertically. Specifically, in this embodiment, the number of rotating claws 1 on the corresponding sensor module is three. From left to right, the first rotating claw 1 has two slide grooves 2 on its circumference, the second rotating claw 1 has three slide grooves 2 on its circumference, and the third rotating claw 1 has four slide grooves 2 on its circumference. The top surface of the rotating claw 1 has a first limiting structure 11.

[0037] The sensor module debugging fixture includes: a base plate 100 , a bracket 200 and a rotating drum 300 .

[0038] The top surface of the base plate 100 has a first mounting hole, and the sensor module has a second mounting hole, and the two are connected and fixed by screws.

[0039] After the sensor module is installed, the bracket 200 is also connected to the base plate 100 by screws.

[0040] The bracket 200 includes a top plate and legs. The upper ends of the legs are connected to the top plate, and the lower ends are screwed to the bottom plate 100. The top plate is located above the sensor module and is provided with a through hole 210 located directly above the rotating claw 1. The through hole 210 is used to allow the rotating drum 300 to pass through. The number of through holes 210 is the same as the number of rotating claws 1 in the sensor module. In this embodiment, there are three through holes 210.

[0041] The bottom of the rotating drum 300 is provided with a second limiting structure 310 that is docked with the first limiting structure 11. The first limiting structure 11 includes a positioning groove, and the second limiting structure 310 includes a positioning protrusion that is plugged into the positioning groove up and down. Specifically, the positioning groove is roughly "T"-shaped, including a first groove extending in the transverse direction, and a second groove extending in the longitudinal direction, and one end of the second groove is connected to the middle of the first groove. Correspondingly, the positioning protrusion is also roughly "T"-shaped, and the positioning protrusion includes a first ridge extending in the transverse direction, and a second ridge extending in the longitudinal direction, and one end of the second ridge is connected to the middle of the first ridge. The "T"-shaped positioning groove and positioning protrusion can play an anti-fool function. After the first limiting structure 11 and the second limiting structure 310 are docked up and down, the rotating drum 300 and the rotating claw 1 have the same rotation state in the horizontal direction, that is, the rotating claw 1 can drive the rotating drum 300 to rotate.

[0042] A spherical elastic plunger 320 is disposed on the sidewall of the rotating drum 300, abutting the wall of the through hole 210. The ball of the spherical elastic plunger 320 can be extended and retracted relative to the outer wall of the rotating drum 300. The spherical elastic plunger 320 and the photosensitive film are co-located horizontally and arranged vertically. That is, in a spatial coordinate system (the horizontal plane is the x- and y-axis directions, and the vertical plane is the z-axis direction), the spherical elastic plunger 320 and the photosensitive film have the same x- and y-axis coordinates, but different z-axis coordinates. The wall of the through hole 210 is provided with an outwardly recessed groove 220, which can be arc-shaped and corresponds to the ball. There are at least two grooves 220 circumferentially. In this embodiment, for the first through hole 210 on the left, there are two grooves 220, forming a 90° angle. For the second through hole 210, there are three grooves 220, and for the third through hole 210, there are four grooves 220, with each adjacent groove 220 forming a 90° angle. The number of the chute 2, photoelectric sensor 3, and grooves 220 is the same, and they correspond one to one. After the ball-end elastic plunger 320 rotates into the groove 220, the ball head of the ball-end elastic plunger 320 pops into the groove 220, temporarily preventing it from rotating further. The extension direction of the groove 220 is perpendicular to the adjustment direction of the corresponding photoelectric sensor 3.

[0043] In order to facilitate the installation of the rotating drum 300, a hook 330 is provided on the top of the rotating drum 300 for convenient vertical lifting. The hook 330 is threadedly connected to the rotating drum 300 and can be replaced.

[0044] The top plate is marked with an arrow indicating the rotation direction of the rotating claw 1, which reminds the user to rotate the rotating claw 1 in the direction of the arrow during debugging to avoid additional debugging steps caused by reverse rotation.

[0045] Furthermore, the first mounting holes on the base plate 100 are arranged in a matrix, and some of the first mounting holes are used to connect with the second mounting holes on the sensor module. The first mounting holes arranged in a matrix can match different types of sensor modules.

[0046] During adjustment, the sensor module to be debugged must first be installed on the base plate 100, and then the bracket 200 must be installed on the base plate 100. Next, the first rotating drum 300 on the left is placed vertically, passing through the through-hole 210 on the top plate. The second limiting structure 310 at the lower end of the rotating drum 300 mates with the first limiting structure 11 at the top of the rotating claw 1. At this point, the ball-end elastic plunger 320 may be in an extended state and located within the groove 220. The user can then directly adjust the position of the photoelectric sensor 3 within the chute 2, facing the ball-end elastic plunger 320, so that the light emitted by the ball-end elastic plunger 320 is blocked by the photosensitive film. The photoelectric sensor 3 is then fixed to the chute 2 using the locking screw, thus securing the position of the photoelectric sensor 3. The ball-end elastic plunger 320 may also be in a compressed state and abut against the wall of the through-hole 210. The user needs to drive the rotating claw 1 to rotate the ball-end elastic plunger 320 to enter the groove 220, and then adjust the position of the photoelectric sensor 3 so that the light emitted by the photosensitive film is blocked. After one photoelectric sensor is adjusted, the rotating claw 1 is driven to rotate, causing the ball-end elastic plunger 320 to enter the next groove 220. The position of the corresponding photoelectric sensor 3 is then adjusted so that the light it emits is blocked by the photosensitive sheet. This continues until all photoelectric sensors 3 are adjusted. The position of the next photoelectric sensor 3 on the circumference of the rotating claw 1 is then fixed. Using the fixed grooves 220 on the bracket 200 to position each photoelectric sensor 3 improves the uniformity of mass-produced sensor modules.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
