Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, and in particular relates to a battery filling hole detection device. Background Technology

[0002] In battery manufacturing, two electrolyte filling processes are typically required. After the first filling, the filling holes are sealed with adhesive pins. Once the electrolyte has fully saturated the electrode materials, the electrolyte capacity will decrease, necessitating the removal of the adhesive pins for the second filling. Before the second filling, the filling holes are usually inspected to ensure no adhesive pins are present, thus guaranteeing a smooth second filling process.

[0003] In existing technologies, the presence of foreign objects at the battery filling hole is mostly determined by manual visual inspection, which is labor-intensive and prone to errors, affecting subsequent secondary filling processes. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a battery filling hole detection device, thereby enabling the detection of battery filling holes.

[0005] In view of this, the present invention provides a battery filling hole detection device, comprising:

[0006] Base frame;

[0007] The detection device is used to detect whether there are foreign objects at the electrolyte filling hole of the battery under test;

[0008] A mobile device, mounted on a base frame, is used to drive the detection device to move along a first direction and a second direction;

[0009] A conveying device, installed inside the base frame, is used to transport the battery under test along a third direction through the testing device.

[0010] A fixing device, mounted on the base frame, is used to position the batteries that have passed through the detection device on the conveying device.

[0011] Furthermore, the detection device includes:

[0013] Several detection components are mounted on the connecting plate in a third direction.

[0014] Furthermore, the detection components include:

[0015] A mounting base is movably mounted on the connecting plate in a third direction;

[0016] The probe is movably mounted on the fixed base in a first direction.

[0017] An elastic element is installed between the probe and the fixed base, and abuts against the fixed base and the probe in the first direction;

[0018] The sensing element is mounted on a fixed base and is used to sense whether the probe has moved along a first direction.

[0019] Furthermore, the connecting plate includes:

[0020] The adjusting groove and the fixing base can be movably installed on the adjusting groove in a third direction;

[0021] The mounting base is secured by fasteners.

[0022] Furthermore, the mobile device includes:

[0023] The lifting mechanism has a detection device mounted on its output end. The lifting mechanism is used to drive the detection device to move along a first direction.

[0024] The translation mechanism and the lifting mechanism are installed on the output end of the translation mechanism. The translation mechanism is installed on the base frame to drive the lifting mechanism to move in the second direction.

[0025] Furthermore, the fixing device includes:

[0026] Two fixing mechanisms are installed on the base frame and located on both sides of the conveying device along the second direction X.

[0027] When the battery under test is transported past the testing device, two fixing mechanisms abut against the battery under test along the second direction X.

[0028] Furthermore, the fixed mechanism includes:

[0029] The base is mounted on the base frame;

[0030] The driver component is mounted on the base.

[0031] The abutment is mounted on the output end of the drive component;

[0032] The driving component is used to control the movement of the abutment component along the second direction.

[0033] Furthermore, the conveying device is a conveyor belt, used to transport the battery under test along a third direction.

[0034] Furthermore, it also includes:

[0035] Several positioning blocks are set on the conveyor belt and move along the third direction Y as the conveyor belt moves;

[0036] The space between two adjacent positioning blocks is used to place the battery to be tested.

[0037] Furthermore, the framework also includes:

[0038] Two guiding mechanisms are mounted on the base frame and located on both sides of the conveying device along the second direction X.

[0039] The guiding mechanism is used to guide the battery under test moving along the Y direction on the conveying device.

[0040] The beneficial effects of the utility model are:

[0041] When the battery conveying device reaches below the testing device, the fixing device clamps and secures the conveying device. Then, the moving device drives the testing device to move along the first direction Z, bringing it close to the battery's electrolyte filling hole for inspection to determine if there are any foreign objects. If no foreign objects are detected at the battery's electrolyte filling hole, the conveying device will transport the battery to the electrolyte filling station for electrolyte filling. If foreign objects are detected at the battery's electrolyte filling hole, the problematic battery will be removed before the conveying device reaches the electrolyte filling station. This reduces manual labor, improves production automation, and increases testing accuracy, thereby effectively improving production efficiency and economic benefits. Attached Figure Description

[0046] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0048] Example 1:

[0049] This embodiment provides a battery filling hole detection device, including:

[0050] Base frame 1;

[0051] Detection device 2 is used to detect whether there are foreign objects at the electrolyte filling hole of the battery under test;

[0052] A mobile device is mounted on the base frame 1 and is used to drive the detection device 2 to move along the first direction Z and the second direction X.

[0053] The conveying device 3 is installed inside the base frame 1 and is used to transport the battery to be tested along the third direction Y through the detection device 2.

[0054] A fixing device is installed on the base frame 1 and is used to position the battery on the conveying device 3 that has passed through the detection device 2.

[0055] In this technical solution, the mobile device first controls the detection device 2 to move along the second direction X, positioning it above the conveying device 3. Then, batteries requiring secondary electrolyte injection are placed on the conveying device 3 for transport. The conveying device 3 transports several batteries from below the detection device 2. When the batteries are transported by the conveying device 3 to below the detection device 2, a fixing device clamps and secures them to the conveying device 3. The mobile device then drives the detection device 2 to move along the first direction Z, bringing it close to the battery's electrolyte injection hole for inspection to determine if any foreign objects are present. If no foreign objects are detected at the battery's electrolyte injection hole, the conveying device 3 transports the battery to the electrolyte injection station for electrolyte injection. If foreign objects are detected at the battery's electrolyte injection hole, the problematic batteries are removed before the conveying device 3 delivers them to the electrolyte injection station. This reduces manual labor, improves production automation and inspection accuracy, thereby effectively increasing production efficiency and economic benefits.

[0056] Furthermore, the detection device 2 includes:

[0057] Connecting plate 21 is mounted and connected to the output end of the mobile device;

[0058] Several detection components are mounted on the connecting plate 21, which can be moved along a third direction Y.

[0059] With this structural design, multiple detection components are installed on the output end of the mobile device, and the spacing between each detection component can be adjusted according to the spacing between two adjacent batteries on the transmission device 3, thereby enabling multiple batteries to be tested on the transmission device 3 to be detected synchronously, effectively improving detection efficiency.

[0060] Furthermore, the detection components include:

[0061] Fixing base 22 is movably mounted on connecting plate 21 in the third direction Y;

[0062] Probe 23 is mounted on the fixed base 22 in a movable manner along the first direction Z.

[0063] The elastic element 24 is installed between the probe 23 and the fixed base 22, and abuts against the fixed base 22 and the probe 23 along the first direction Z;

[0064] The sensor 25 is mounted on the fixed base 22 and is used to sense whether the probe 23 moves along the first direction Z.

[0065] A sleeve 27 is provided on the fixed base 22. The probe 23 is movably mounted on the fixed base 22 along the first direction Z. One end of the probe 23 is located below the fixed base 22 along the first direction Z for contacting the battery, and the other end passes through the fixed base 22 and is located inside the sleeve 27. The elastic element 24 can be a spring, which is sleeved on the probe 23. The two ends of the spring abut against the end of the probe 23 for contacting the battery and the bottom of the fixed base 22, respectively. The sensing element 25 is provided on the fixed base 22 and located above the sleeve 27 along the first direction Z. The sensing element 25 is a photoelectric sensor, or it can be a slotted photoelectric sensor.

[0066] When the detection component is working, the moving device drives the connecting plate 21 to move along the first direction Z, which in turn moves the fixed base 22 along the first direction Z, causing the probe 23 on the fixed base 22 to approach the battery under test on the conveying device 3. If there are no foreign objects at the filling hole of the battery under test, the end of the probe 23 near the battery will contact the filling hole, the spring will be compressed, and the other end of the probe 23 will move upward along the first direction Z to form a fixed detection distance with the slotted photoelectric sensor. The photoelectric signal will indicate that the battery filling hole is normal. If there are foreign objects at the filling hole of the battery under test, the end of the probe 23 near the battery will contact the foreign objects at the filling hole, the spring compression will increase, and the detection distance formed by the other end of the probe 23 and the slotted photoelectric sensor will change. The photoelectric signal will indicate that the battery filling hole is abnormal.

[0068] This embodiment provides a battery filling hole detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0069] Furthermore, the connecting plate 21 includes:

[0070] The adjusting groove 26 and the fixing seat 22 are movable along the third direction Y and are mounted on the adjusting groove 26;

[0071] The fixing base 22 is fixed by fasteners.

[0072] In this technical solution, an adjustment groove 26 is provided on the connecting plate 21, and a connecting hole is provided on the fixed seat 22. The connecting hole is connected to the adjustment groove 26. Then, a fastener is provided to pass through the adjustment groove 26 and be threaded to the connecting hole. Then, the position of the fixed seat 22 is adjusted by moving it along the third direction Y. Finally, the fastener is tightened to lock the fixed seat 22 and the connecting plate 21.

[0078] In this technical solution, the translation mechanism 5 first drives the lifting mechanism 4 to move along the second direction X, which in turn moves the detection device 2 on the lifting mechanism 4 to the top of the conveying device 3. Then, when the detection operation is performed, the lifting mechanism 4 drives the detection device 2 to move down along the first direction Z to detect the liquid injection hole of the battery to be tested transported on the conveying device 3.

[0079] The lifting mechanism 4 can be a pneumatic cylinder, an electric cylinder, or a screw drive module, as long as it can drive the detection device 2 to move quantitatively along the first direction Z; preferably, the lifting mechanism 4 is a pneumatic cylinder, which has a simple structure and can respond quickly. The translation mechanism 5 can be a slide cylinder module, a screw drive module, or other drive mechanism that can drive the lifting mechanism 4 to move quantitatively along the second direction X.

[0082] Furthermore, the fixing device includes:

[0083] Two fixing mechanisms 6 are installed on the base frame 1 and are located on both sides of the conveying device 3 along the second direction X.

[0084] When the battery under test is transported past the detection device 2, the two fixing mechanisms 6 approach the battery under test along the second direction X.

[0085] Furthermore, the fixing mechanism 6 includes:

[0086] Base 61, which is mounted on base frame 1;

[0087] Drive component 62 is mounted on base 61;

[0088] Abutting member 63 is mounted on the output end of the driving member 62;

[0089] The driving component 62 is used to control the abutment component 63 to move along the second direction X.

The cylinder is mounted on the base 61, and a slide rail 64 arranged along the second direction X is mounted on the base 61. The bottom of the abutment 63 is provided with a slide seat that is adapted to and connected to the slide rail 64.

[0091] When the conveying device 3 transports the battery to be tested to the bottom of the testing device 2, the two driving components 62 respectively control the two abutting components 63 to move along the second direction X and abut against the battery, thereby achieving the clamping and fixing of the battery.

[0092] Furthermore, a groove is provided on the end face of the abutment 63 that contacts the battery. The groove structure is adapted to both ends of the battery along the second direction X. When the abutment 63 abuts against the battery, the end of the battery along the second direction X is adapted to the groove for insertion. Through this structural design, the clamping stability of the battery is effectively enhanced.
