Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and more specifically, to a glue nail detection mechanism and a nail removal device. Background Technology

[0002] During battery production, temporary glue pins are inserted into the electrolyte filling port of the battery through a plugging mechanism between transfers. Before each process, the temporary glue pins are removed by a plugging machine to prevent foreign objects, metal dust, etc. from entering the battery and causing a short circuit, as well as to prevent electrolyte evaporation from affecting battery quality and polluting the workshop environment.

[0003] Currently, manual visual inspection and fixed sensors are commonly used to inspect the rubber nails at the injection port. The former has the risk of low efficiency and large detection error, while the latter has the problem of insufficient detection flexibility. Utility Model Content

[0004] The purpose of this invention is to provide a new technical solution for a glue nail detection mechanism and a nail removal device.

[0005] According to one aspect of the present invention, a glue nail detection mechanism is provided.

[0006] The glued nail testing mechanism includes:

[0007] A frame, on which a tray is provided for holding the battery to be tested;

[0008] A first support member and a first driving member are respectively disposed on the frame, and the driving end of the first driving member is connected to the first support member in a transmission manner. Under the drive of the first driving member, the first support member can move along a first direction and move closer to or further away from the tray.

[0009] A sensor and a second driving member are respectively disposed on the first support member, and the driving end of the second driving member is connected to the sensor. Under the drive of the second driving member, the sensor can move along a second direction and move closer to or away from the tray. The sensor can detect the liquid injection hole of the battery to be tested on the tray, wherein the second direction is perpendicular to the first direction.

[0010] Optionally, one of the second direction and the first direction is parallel to the arrangement direction of the batteries to be tested in the tray.

[0011] Optionally, both the second direction and the first direction are horizontal.

[0012] Optionally, the first direction is the left-right direction, and the second direction is the front-back direction.

[0013] Optionally, it further includes a third driving member and a second support member. The second support member and the third driving member are respectively on the frame. The first support member and the first driving member are both disposed on the second support member. The driving end of the third driving member is connected to the second support member in a transmission manner. Under the drive of the third driving member, the second support member can move along a third direction and move closer to or away from the tray. The third direction, the second direction and the first direction are perpendicular to each other.

[0014] Optionally, the third direction is the vertical direction.

[0015] Optionally, the frame has a first guide rail, and the first support member is slidable along the first guide rail.

[0016] Optionally, the first support member has a second guide rail, the sensor is slidable along the second guide rail, and the extension direction of the second guide rail is perpendicular to the extension direction of the first guide rail.

[0017] Optionally, the top two ends of the rack are each provided with a first support member and a first drive member, and the tray is connected to the top of the rack.

[0018] According to another aspect of the present invention, a nail removal device is provided, including the aforementioned nail detection mechanism.

[0019] One technical advantage of this utility model is:

[0020] The glue nail detection mechanism includes a frame, a first support member, a first drive member, a sensor, and a second drive member. The frame has a tray for supporting the battery to be tested. The first support member and the first drive member are respectively mounted on the frame, and the drive end of the first drive member is tractively connected to the first support member. Under the drive of the first drive member, the first support member can move along a first direction, approaching or moving away from the tray. The second drive member and the sensor are respectively mounted on the first support member, and the drive end of the second drive member is tractively connected to the sensor. Under the drive of the second drive member, the sensor can move along a second direction, approaching or moving away from the tray. The sensor can detect the electrolyte filling hole of the battery to be tested on the tray, wherein the second direction is perpendicular to the first direction.

[0021] In this way, the first driving component drives the first support component to move along the first direction, and the second driving component drives the sensor to move along the perpendicular second direction, forming an orthogonal motion axis system.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] This invention provides a glue nail detection mechanism for detecting the electrolyte filling hole of a battery to be tested, so as to ensure that the glue nail has been reliably removed, thereby ensuring the reliability and safety of subsequent processing.

[0033] like Figure 1 As shown, the glue nail detection mechanism provided by this utility model includes:

[0034] A frame 1 is provided with a tray 11, which is used to hold the battery to be tested.

[0035] The first support member 2 and the first drive member 3 are respectively disposed on the frame 1, and the drive end of the first drive member 3 is connected to the first support member 2 in a transmission manner. Under the drive of the first drive member 3, the first support member 2 can move along the first direction and move closer to or away from the tray 11.

[0036] Sensor 4 and second driving member 5 are respectively disposed on the first support member 2, and the driving end of the second driving member 5 is connected to the sensor 4 in a transmission manner. Under the drive of the second driving member 5, the sensor 4 can move along the second direction and move closer to or away from the tray 11. The sensor 4 can detect the liquid injection hole of the battery to be tested on the tray 11, wherein the second direction is perpendicular to the first direction.

[0037] Specifically, the frame 1 can be made of aluminum alloy profiles or welded steel plates to ensure overall rigidity and stability. Anchor bolt holes can be provided at the bottom of the frame 1 to facilitate the fixing of the glue nail detection mechanism.

[0038] The tray 11 is typically bolted to the center of the top of the frame 1 and has a receiving slot for accommodating the battery to be tested. The surface of the receiving slot may have a positioning groove that matches the shape of the battery to be tested, facilitating quick clamping of batteries of different sizes.

[0039] Depending on the actual size of the battery to be tested, multiple batteries can be arranged side by side or in multiple rows, with all the injection holes of the batteries exposed to facilitate detection by sensor 4.

[0040] The first driving component 3 can be a servo motor, cylinder, or other driving structure, which is fixed to the frame 1 by a mounting plate.

[0041] The first support member 2 can be a rectangular aluminum alloy plate, and it can be slidably connected to the linear guide rail of the frame 1 via a slider. Driven by the first driving member 3, the first support member 2 can move along a first direction, for example... Figure 1The left-right reciprocating motion shown allows the detection range of the glue nail detection mechanism to cover the entire tray 11.

[0042] The first support member 2 can adopt a honeycomb panel design for weight reduction and reinforcement, so that it can maintain a stable support force under the drive of the first drive member 3, thereby ensuring the detection reliability of the glue nail detection mechanism.

[0043] The second driving component 5 can be a servo motor, cylinder, or other driving structure. It is mounted on the first support component 2, and its driving end can be connected to the sensor 4 via a floating connector. Under the drive of the second driving component 5, the sensor 4 can move along a second direction, for example... Figure 1 The reciprocating motion shown allows the detection range of the glue nail detection mechanism to cover the entire tray 11. The sensor 4 can be a laser displacement sensor or a vision camera.

[0044] In this way, the first driving component 3 drives the first support component 2 to move along the first direction, and the second driving component 5 drives the sensor 4 to move along the perpendicular second direction, forming an orthogonal motion axis system. This allows the glue pin detection mechanism to accurately cover the detection requirements of the electrolyte injection holes of the batteries to be tested at any position on the tray 11, improving the detection flexibility of the glue pin detection mechanism. Moreover, there is no need to manually adjust the position of the batteries to be tested, which is especially suitable for multi-specification battery mixed production lines, improving battery detection efficiency and reducing the impact on production cycle time.

[0045] Among them, sensor 4 can be used in conjunction with laser triangulation and machine vision algorithms to simultaneously detect key parameters such as missing glue nails, offset, and height, making it easier to identify different defects.

[0046] In addition, it can be combined with light compensation technology to eliminate interference such as surface reflection and stains on the battery under test, so as to maintain stable testing performance under complex working conditions.

[0047] Optionally, one of the second direction and the first direction is parallel to the arrangement direction of the batteries to be tested in the tray 11.

[0048] like Figure 1 As shown, the arrangement direction of the single row of batteries to be tested in the tray 11 is left and right. The first direction can also be set to the left and right direction, that is, the movement direction of the first support 2 is left and right, so that the sensor 4 can move along the arrangement direction of the single row of batteries to be tested and perform detection.

[0049] In another embodiment, the second direction can also be set to be parallel to the arrangement direction of the single row of batteries to be tested in the tray 11, that is, the movement direction of the sensor 4 is the arrangement direction of the single row of batteries to be tested in the tray 11, which also facilitates the comprehensive detection of the sensor 4.

[0050] Optionally, both the second direction and the first direction are horizontal.

[0051] Specifically, the first direction can be set to the left and right direction, and the second direction can be set to the front and back direction, that is, the movement direction of the first support member 2 is the left and right direction, and the movement direction of the sensor 4 is the front and back direction; or the first direction can be set to the front and back direction, and the second direction can be set to the left and right direction, that is, the movement direction of the first support member 2 is the front and back direction, and the movement direction of the sensor 4 is the left and right direction, both of which can achieve comprehensive detection by the sensor 4.

[0052] Furthermore, setting both the second and first directions to be horizontal can prevent damage to the battery under test caused by vertical movement, thus improving the safety of the glue nail testing mechanism.

[0053] Optionally, it also includes a third driving member and a second support member. The second support member and the third driving member are respectively on the frame 1. The first support member 2 and the first driving member 3 are both disposed on the second support member. The driving end of the third driving member is connected to the second support member in a transmission manner. Under the drive of the third driving member, the second support member can move along a third direction and move closer to or away from the tray 11. The third direction and the second direction are perpendicular to each other with the first direction.

[0054] Specifically, the second support member can be a rectangular aluminum alloy plate, and it can be slidably connected to the linear guide rail of the frame 1 via a slider. Driven by the third drive member, the second support member can move along a third direction, for example... Figure 1 The vertical reciprocating motion shown drives the first support member 2 and the first driving member 3 on it to also move in a third direction, for example... Figure 1 The vertical reciprocating motion shown allows the glue nail testing mechanism to adapt to the testing needs of batteries of different sizes.

[0055] The design incorporates a three-dimensional motion axis system, where the third direction, the second direction, and the first direction are perpendicular to each other. This allows the glue nail testing mechanism to accurately cover the testing requirements of the liquid injection holes of the batteries to be tested at any position on the tray 11, and also makes it easier for the glue nail testing mechanism to adapt to the testing requirements of batteries of different sizes.

[0056] Optionally, the third direction is the vertical direction.

[0057] Specifically, driven by the third driving component, the second support component can move along a third direction, for example... Figure 1 The vertical reciprocating motion shown drives the first support member 2 and the first driving member 3 on it to also move in a third direction, for example... Figure 1 The vertical reciprocating motion shown allows the glue nail testing mechanism to adapt to the testing needs of batteries of different sizes.

[0058] Optionally, the frame 1 has a first guide rail, and the first support member 2 is slidable along the first guide rail.

[0059] Specifically, the first support member 2 has a slider. Under the drive of the first driving member 3, the slider can slide in the first guide rail and drive the first support member 2 to move in the first direction, thereby controlling the movement path of the first support member 2 and ensuring the reliability and controllability of the movement of the first support member 2.

[0060] Optionally, the first support member 2 has a second guide rail, the sensor 4 is slidable along the second guide rail, and the extension direction of the second guide rail is perpendicular to the extension direction of the first guide rail.

[0061] Specifically, the sensor 4 also has a slider. Under the drive of the second driving member 5, the slider can slide in the second guide rail and drive the sensor 4 to move in the second direction, thereby controlling the movement path of the sensor 4 and ensuring the reliability and controllability of the movement of the sensor 4.

[0062] Optionally, the top two ends of the frame 1 are each provided with a first support member 2 and a first drive member 3, and the tray 11 is connected to the top of the frame 1. That is, the tray 11 is located in the middle, while the top two ends of the frame 1 each have a first support member 2, a first drive member 3, a second drive member 5, and a sensor 4. The two sensors 4 can independently detect the electrolyte filling holes of the batteries to be tested in the tray 11, which facilitates improved detection efficiency.

[0063] This utility model also provides a nail removal device, including the aforementioned nail detection mechanism. The nail detection mechanism is used to detect the electrolyte injection hole of the battery to be tested after the nail removal process is completed, so as to ensure the reliability of the nail removal process and ensure the reliable and safe execution of subsequent processes.

[0064] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
