Description

Technical Field

[0001] The present invention relates to the field of battery tanks, and in particular to a battery tank detection device and method. Background Art

[0002] The battery container is a solid structure used to fix and protect the battery. The battery container made of PP material is one of the common battery containers. It has low cost, simple molding and good economic benefits.

[0003] However, when PP material is injection molded, due to the large shrinkage rate of the PP plastic shell, it is generally necessary to test the depth of the battery container after the PP material is processed.

[0004] The existing detection method is to manually use a vernier caliper to detect the depth of the battery slot. This detection method is relatively cumbersome to operate, and the vernier caliper needs to be locked in place during detection. The cumbersome operation is more obvious when performing multi-point measurements on the battery slot. Therefore, a battery slot detection device and method are urgently needed to solve the above problems. Summary of the invention

[0005] The present invention discloses a battery slot detection device and method. A laser rangefinder is provided. The laser rangefinder can move on the top of the battery slot body, thereby realizing multi-point measurement, thereby reducing the error in the measurement result, and solving the technical problem raised in the background technology.

[0006] Technical solution: The present invention provides a battery slot detection device, including a frame, a moving rod slidably connected in the frame, a moving device slidably connected on the moving rod, a laser rangefinder is arranged on the moving device, the detection end of the laser rangefinder is vertically downward and points to the plane to be detected, and the sliding direction of the moving device is perpendicular to the sliding direction of the moving rod.

[0007] Furthermore, two opposite side surfaces of the frame are provided with sliding grooves, and sliders are slidably connected in the two sliding grooves, and both ends of the connecting moving rod are fixedly connected to the sliders.

[0008] Furthermore, the moving device is provided with a first through hole along the sliding direction, and the moving device is sleeved on the moving rod through the first through hole and is slidably connected with the moving rod.

[0009] Furthermore, a U-shaped plate with an opening facing downward is fixedly connected to the top of the moving device, and a second through hole is opened at corresponding positions of the moving device and the top of the U-shaped plate. The positioning rod passes through the second through hole, and a spring is sleeved on the positioning rod located inside the U-shaped plate, and a limit plate is sleeved on the positioning rod below the spring.

[0010] Furthermore, the length of the positioning rod at the bottom of the limiting plate is greater than the depth of the second through hole provided in the moving device.

[0011] Furthermore, the diameter of the limiting plate is larger than the diameter of the second through hole provided in the moving device.

[0012] Furthermore, clamping grooves are fixedly connected to both sides of the bottom of the frame.

[0013] Furthermore, a guide surface is provided on the clamping side wall of the clamping groove body.

[0014] The present invention also provides a detection method for a battery slot detection device, comprising the following steps:

[0015] Step 1: Clamp the clamping trough to the top frame of the battery trough, so as to conveniently fix the inspection fixture to the top of the battery trough, and ensure that the detection end of the laser rangefinder points to the inner bottom of the battery trough;

[0016] Step 2: Control the laser rangefinder to detect the battery tank and change the position of the moving rod to detect the depth of multiple points in the battery tank;

[0017] Step 3: Apply an upward force to the positioning rod, thereby further compressing the spring, and then causing the positioning rod to move upward a certain distance as a whole, so that its bottom no longer presses against the moving rod. At this time, the moving device can move on the moving rod, so that the laser rangefinder is located at a specified position of the moving rod, and a multi-point detection operation on the same straight line of the bottom of the battery tank body is realized;

[0018] Step 4: After the test is completed, turn off the laser rangefinder, remove the clamping trough from the battery trough, and wait for subsequent testing. Beneficial Effects

[0019] The present invention utilizes a laser rangefinder to detect the depth of a battery tank body, and the laser rangefinder can change its own position, so that the depths of multiple points of the battery tank body can be detected, thereby simplifying the operation of personnel.

[0020] The movable rod of the present invention can slide under the action of the slider and the slide groove, and the sliding path of the slider in the slide groove is limited, so the sliding path of the movable rod is also limited, thereby ensuring that the laser rangefinder moves in a specified area.

[0021] The spring of the present invention is in a compressed state, so it exerts force on the limit plate, so that the limit plate contacts the top of the moving device, so that the bottom of the positioning rod presses against the moving rod, and then the moving device is fixed on the moving rod, preventing the position of the laser rangefinder relative to the moving rod from changing.

[0022] When the positioning rod of the present invention is subjected to an upward force, the limit plate will be driven to move upward to further compress the spring, so that the positioning rod as a whole moves upward a certain distance, so that its bottom no longer presses against the moving rod, so that the laser rangefinder can change its own position relative to the moving rod.

[0032] Embodiment 1:

[0033] like Figure 1-4 As shown, a battery slot detection device includes a frame 1, a moving rod 4 is slidably connected inside the frame 1, a moving device 5 is slidably connected to the moving rod 4, a laser rangefinder 6 is arranged on the moving device 5, a detection end of the laser rangefinder 6 is vertically downward and points to a plane to be detected, and a sliding direction of the moving device 5 is perpendicular to the sliding direction of the moving rod 4.

[0034] The frame 1 can be placed on the top of the battery slot 14. At this time, the detection end of the laser rangefinder 6 will be aligned with the inner bottom of the battery slot 14. Therefore, the laser rangefinder 6 can detect the depth of the battery slot 14 and determine whether the depth of the battery slot 14 meets the requirements. Moreover, since the moving rod 4 and the moving device 5 can both slide and the sliding directions of the two are perpendicular to each other, the laser rangefinder 6 can detect the depth of multiple points of the battery slot 14 to simplify the operation of personnel.

[0035] Slide grooves 2 are provided on the two opposite side surfaces of the frame 1, and sliders 3 are slidably connected in the two slide grooves 2. Both ends of the connecting moving rod 4 are fixedly connected to the sliders 3. The slider 3 can only slide in the slide grooves 2, so that the moving rod 4 slides under the action of the sliders 3 and the slide grooves 2 to change the position of the laser rangefinder 6.

[0036] A first through hole 7 is provided on the side of the moving device 5 , and the moving device 5 is sleeved on the periphery of the moving rod 4 through the first through hole 7 and is slidably connected to the moving rod 4 , so that the moving device 5 can slide on the moving rod 4 to change the position of the laser rangefinder 6 .

[0037] A U-shaped plate 8 with an opening downward is fixedly connected to the top of the moving device 5, and a second through hole 12 is opened at corresponding positions on the top of the moving device 5 and the U-shaped plate 8. The positioning rod 9 passes through the second through hole 12, and a spring 10 is sleeved on the positioning rod 9 located inside the U-shaped plate 8, and a limiting plate 11 is sleeved on the positioning rod 9 below the spring 10. The length of the positioning rod 9 at the bottom of the limiting plate 11 is greater than the depth of the second through hole 12 provided on the moving device 5, and the outer diameter of the limiting plate 11 is greater than the diameter of the second through hole 12 provided on the moving device 5. Since the spring 10 is always in a compressed state, it will apply force to the limiting plate 11, so that the limiting plate 11 contacts the top of the moving device 5, and then the bottom of the positioning rod 9 is against the moving rod 4, so as to fix the moving device 5 on the moving rod 4, avoid the change of the position of the laser rangefinder 6 relative to the moving rod 4 during the movement of the moving rod 4, and realize the multi-point position detection operation of the same straight line at the bottom of the battery slot 14.

[0038] When it is necessary to adjust the position of the laser rangefinder 6 relative to the moving rod 4, an upward force can be applied to the positioning rod 9, so that the limit plate 11 moves upward to further compress the spring 10, thereby causing the positioning rod 9 to move upward a certain distance as a whole so that its bottom no longer rests against the moving rod 4. At this time, personnel can manually apply a moving force to the mobile device 5 to move it on the moving rod 4, so that the laser rangefinder 6 is located at the specified position of the moving rod 4.

[0039] The frame 1 is fixedly connected with a clamping groove 13 on both sides of the bottom, and the clamping groove 13 can clamp the top frame of the battery groove 14, so that the inspection tool is conveniently fixed to the top of the battery groove 14, and the clamping side wall of the clamping groove 13 is provided with a guide surface, which can make the clamping groove 13 easy to engage with the top frame of the battery groove 14, so that personnel can use the inspection tool to detect the depth of the battery groove 14.

[0040] Embodiment 2:

[0041] With respect to the battery slot detection device disclosed in Embodiment 1, the present invention further discloses a detection method based on the battery slot detection device, comprising the following steps:

[0042] Step 1: Clamp the clamping tank 13 to the top frame of the battery tank 14, so as to conveniently fix the inspection fixture to the top of the battery tank 14, and ensure that the detection end of the laser rangefinder 6 points to the inner bottom of the battery tank 14;

[0043] Step 2: Control the laser rangefinder 6 to detect the battery slot 14 and change the position of the moving rod 4 to detect the depth of multiple points in the battery slot 14;

[0044] Step 3: Apply an upward force to the positioning rod 9, thereby further compressing the spring 10, so that the positioning rod 9 moves upward for a certain distance as a whole, so that the bottom of the positioning rod 9 no longer presses against the moving rod 4. At this time, the moving device 5 can move on the moving rod 4, so that the laser rangefinder 6 is located at a specified position of the moving rod 4, and a multi-point detection operation on the same straight line of the bottom of the battery slot 1414 is realized;

[0045] Step 4: After the detection is completed, turn off the laser rangefinder 6, remove the clamping slot 13 from the battery slot 14, and wait for subsequent detection.

[0046] For the above detection method, the clamping slot 13 is easily fixed on the top frame of the battery slot 14, so that the laser rangefinder 6 can detect the depth of the battery slot 14, and the position of the laser rangefinder 6 is convenient for movement on a plane, therefore, the laser rangefinder 6 can detect the depth of multiple points of multiple battery slots 14.

[0047] Working principle: The frame 1 can be placed on the top of the battery slot 14, and it is necessary to ensure that the detection end of the laser rangefinder 6 is aligned with the inner bottom of the battery slot 14. In addition, since the moving rod 4 and the moving device 5 can both slide, and the sliding directions of the two are perpendicular, when the laser rangefinder 6 is working, the depth of multiple points of the battery slot 14 can be detected to simplify the operation of personnel.

[0048] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent transformation or modification made according to the spirit of the present invention should be included in the protection scope of the present invention.
