Description

Technical Field

[0001] This utility model relates to the field of battery production equipment, and more specifically, to a liquid injection hole positioning device. Background Technology

[0002] There are two common methods for filling button cells with electrolyte: the first is to fill the electrolyte first and then weld the top cover; the second is to weld the top cover first, leaving an electrolyte filling hole on the top cover, and then welding it in. The second method requires locating the electrolyte filling hole before filling. Current technologies offer two methods for locating the filling hole: one is manual visual inspection, which is flexible but inefficient; the other is using a combination of CCD and a robotic arm for hole positioning, but this method is very expensive.

[0003] Therefore, existing technologies suffer from the problem of finding battery injection holes efficiently and at low cost. Utility Model Content

[0004] The main objective of this invention is to provide a liquid injection hole positioning device to solve the problem of finding the battery liquid injection hole efficiently and at low cost in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, an injection hole positioning device is provided, comprising: a clamping assembly for clamping a battery; a first driving assembly, at least a portion of which extends into the clamping assembly and drives at least a portion of the clamping assembly to rotate the battery relative to at least another portion of the clamping assembly; a first detection assembly that slides in contact with the battery, and at least a portion of which moves along the thickness direction of the battery; and a second detection assembly disposed at the end of the first detection assembly away from the battery and used to detect the movement of the first detection assembly.

[0006] Furthermore, the second detection component is signal-connected to the first drive component.

[0007] Furthermore, the clamping assembly includes at least one clamping portion, which includes: a mounting cylinder having a receiving cavity, a first opening communicating with the receiving cavity at the top of the mounting cylinder, and a second opening communicating with the receiving cavity at the circumferential sidewall of the mounting cylinder; a clamping member, at least a portion of which is located within the receiving cavity, and at least another portion of which extends out of the receiving cavity through the first opening; a first driving assembly extending into the receiving cavity through the second opening and driving the clamping member to rotate relative to the mounting cylinder; and the portion of the clamping member located outside the receiving cavity is used to clamp the battery.

[0008] Furthermore, the first drive assembly includes: a first drive unit; a transmission member, wherein the first drive unit is drivenly connected to the transmission member and drives the transmission member to rotate, and at least a portion of the transmission member can extend into the receiving cavity through the second opening and drive the clamping member to rotate relative to the mounting cylinder.

[0009] Furthermore, the first drive assembly also includes a second drive unit, which is drivenly connected to the first drive unit and drives the first drive unit and the transmission member to move in a direction close to or away from the clamping assembly, so that the transmission member can enter or exit the receiving cavity.

[0010] Furthermore, the injection hole positioning device also includes: a mounting plate, on which at least a portion of the first driving unit and at least a portion of the second driving unit are movably disposed; and a guide assembly, on which the mounting plate is movably disposed, and the guide assembly and the mounting plate have mutually cooperating guide structures.

[0011] Furthermore, the injection hole positioning device also includes at least one second driving component, which is disposed on the side of the clamping component away from the first driving component and drives the clamping component to move in a direction close to or away from the first driving component.

[0012] Furthermore, the injection hole positioning device also includes a first mounting bracket, and the clamping assembly and the second drive assembly are respectively mounted on the first mounting bracket.

[0013] Furthermore, the second detection component is located on the side of the first detection component away from the clamping component.

[0014] Furthermore, the injection hole positioning device also includes: a second mounting bracket; a third driving unit, the third driving unit being disposed on the second mounting bracket; the third mounting bracket, the first detection component and the second detection component being respectively disposed on the third mounting bracket, and the third driving unit being drivenly connected to the third mounting bracket so that the first detection component can move in a direction close to or away from the clamping component.

[0015] Applying the technical solution of this utility model, the liquid injection hole positioning device in this application includes a clamping assembly, a first driving assembly, a first detection assembly, and a second detection assembly. The clamping assembly is used to clamp the battery; at least a portion of the first driving assembly is used to extend into the clamping assembly and drive at least a portion of the clamping assembly to rotate the battery relative to at least another portion of the clamping assembly; the first detection assembly slides in contact with the battery, and at least a portion of the first detection assembly is used to move along the thickness direction of the battery; the second detection assembly is disposed at the end of the first detection assembly away from the battery and is used to detect the movement of the first detection assembly.

[0016] When using the electrolyte filling hole positioning device of this application, the clamping component can clamp the battery to be located for the electrolyte filling hole. After the clamping component completes clamping the battery, the first driving component drives the clamping component to rotate, thereby causing the clamping component to rotate the battery relative to the first detection component. Since the first detection component is in sliding contact with the battery, it can contact the battery at different positions as the battery rotates with the support component. When the battery rotates to the position where its electrolyte filling hole is opposite the first detection component, at least a part of the first detection component can move along the thickness direction of the battery. Therefore, one end of the first detection component can enter the electrolyte filling hole, and the movement of the first detection component is detected by the second detection component, thus confirming that the electrolyte filling hole has been found. Therefore, the electrolyte filling hole positioning device of this application is more efficient than the manual hole finding method and is less expensive than the existing hole positioning method using the linkage of CCD and robotic arm. Thus, the electrolyte filling hole positioning device of this application effectively solves the problem of difficulty in efficiently and cost-effectively locating battery electrolyte filling holes in the prior art.

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.

[0025] To address the problem of finding battery injection holes efficiently and cost-effectively in the prior art, this application provides an injection hole positioning device.

[0026] like Figure 1 and Figure 2As shown, the liquid injection hole positioning device in this application includes a clamping assembly 10, a first driving assembly 20, a first detection assembly 30, and a second detection assembly 40. The clamping assembly 10 is used to clamp the battery; at least a portion of the first driving assembly 20 is used to extend into the clamping assembly 10 and drive at least a portion of the clamping assembly 10 to rotate the battery relative to at least another portion of the clamping assembly 10; the first detection assembly 30 is in sliding contact with the battery, and at least a portion of the first detection assembly 30 is used to move along the thickness direction of the battery; the second detection assembly 40 is disposed at the end of the first detection assembly 30 away from the battery and is used to detect the movement of the first detection assembly 30.

[0027] When using the injection hole positioning device of this application, the clamping component 10 can clamp the battery whose injection hole is to be located. After the clamping component 10 completes clamping the battery, the first driving component 20 drives the clamping component 10 to rotate, thereby causing the clamping component 10 to drive the battery to rotate relative to the first detection component 30. Since the first detection component 30 is in sliding contact with the battery, it can contact different positions of the battery as the battery rotates with the support component. When the battery rotates to the position where its injection hole is opposite the first detection component 30, at least a part of the first detection component 30 can move along the thickness direction of the battery. Therefore, one end of the first detection component 30 can enter the injection hole, and the movement of the first detection component 30 is detected by the second detection component 40, thus confirming that the injection hole has been found. Therefore, the injection hole positioning device of this application is more efficient than the manual hole-finding method and has a lower cost compared with the existing method of hole positioning through the linkage of CCD and robotic arm. Therefore, the liquid injection hole positioning device in this application effectively solves the problem of finding the battery liquid injection hole efficiently and at low cost in the prior art.

[0028] It should be noted that, in the context of CCD mentioned above, CCD refers to the application of "Charge-Coupled Device" in industrial automation and quality control, specifically a camera technology used for visual inspection. In battery production and assembly, CCD camera systems are commonly used for high-precision position and quality inspection, such as detecting the position of battery tabs and surface defects, to ensure production accuracy and product quality. However, using CCD cameras typically increases overall production costs.

[0029] Optionally, the second detection component 40 is signal-connected to the first drive component 20. With this configuration, when one end of the first detection component 30 enters the injection hole, the first drive component 20 can be stopped in time to drive the clamping component 10 and the battery to rotate, thereby ensuring that one end of the first detection component 30 can remain inserted into the injection hole and preventing the first detection component 30 from damaging the injection hole.

[0030] It should be noted that in this application, the second detection component 40 is used to detect the positional change of the first detection component 30 in the thickness direction of the battery. That is, when one end of the first detection component 30 falls into the battery's filling hole, the position of the first detection component 30 in the thickness direction of the battery, or in the height direction of the filling hole positioning device, will change. At this time, the second detection component 40 will detect the positional change of the first detection component 30, thereby sending a signal to the first drive component 20 and controlling the first drive component 20 to stop driving the clamping component 10 to rotate the battery. Thus, in this application, the automatic hole finding operation of the battery filling hole is achieved by determining whether the first detection component 30 has fallen into the battery's filling hole.

[0031] Furthermore, in this application, the first detection component 30 may include a detection probe, and when the end of the detection probe does not enter the battery's filling hole, the end of the detection probe slides in contact with the battery surface, or in other words, the clamping component 10 can drive the battery to rotate relative to the detection probe. During the battery's rotation, the detection probe remains in contact with the battery. As the battery rotates, when the probe aligns with the battery's filling hole, the end of the detection probe will fall into the filling hole. Therefore, in this application, one end of the detection probe can be elastically extendable; that is, when the detection probe contacts the battery surface, the end of the detection probe is squeezed, and when the end of the detection probe aligns with the filling hole, the end of the detection probe can enter the filling hole under the action of elastic restoring force. At this time, the second detection component 40 can detect the end of the probe. Of course, in this application, the entire detection probe can also be configured to move relative to the battery; that is, when the end of the detection probe is opposite to the battery's filling hole, the entire detection probe will move relative to the battery along the battery's thickness direction, thereby ensuring that the end of the detection probe can enter the filling hole. In this case, the second detection component 40 performs position detection on the entire detection probe.

[0032] The second detection component 40 can be a distance detection sensor or a position detection sensor. In one specific embodiment of this application, the second detection component 40 is a precision photoelectric proximity sensor with a sensing distance of 1 mm.

[0033] Optionally, the clamping assembly 10 includes at least one clamping portion, which includes a mounting cylinder 11 and a clamping member 12. The mounting cylinder 11 has a receiving cavity, and its top has a first opening 111 communicating with the receiving cavity. The circumferential sidewall of the mounting cylinder 11 has a second opening 112 communicating with the receiving cavity. At least a portion of the clamping member 12 is located within the receiving cavity, and at least another portion of the clamping member 12 extends out of the receiving cavity through the first opening 111. The first driving assembly 20 extends into the receiving cavity through the second opening 112 and drives the clamping member 12 to rotate relative to the mounting cylinder 11. The portion of the clamping member 12 outside the receiving cavity is used to clamp the battery. Furthermore, in this application, the portion of the clamping member 12 used to clamp the battery has at least two clamping arms that can move radially along the battery, thereby ensuring that the clamping member 12 can clamp the battery through the clamping arms.

[0034] Optionally, the first drive assembly 20 includes a first drive section 21 and a transmission member 22. The first drive section 21 is drivenly connected to the transmission member 22 and drives the transmission member 22 to rotate. At least a portion of the transmission member 22 can extend into the receiving cavity through the second opening 112 and drive the clamping member 12 to rotate relative to the mounting cylinder 11. Furthermore, in this application, the portion of the transmission member 22 that contacts the clamping member 12 has a disc-shaped structure, while the portion of the clamping member 12 that cooperates with the transmission member 22 can be cylindrical. Thus, after the transmission member 22 extends into the receiving cavity through the second opening 112 and abuts against the clamping member 12, as the first drive section 21 drives the transmission member 22 to rotate, the clamping member 12 can drive the battery to rotate together under the action of friction.

[0035] Optionally, the first drive assembly 20 further includes a second drive unit 23, which is drivenly connected to the first drive unit 21 and drives the first drive unit 21 and the transmission member 22 to move in a direction close to or away from the clamping assembly 10, so that the transmission member 22 can enter or exit the receiving cavity.

[0036] Optionally, the injection hole positioning device further includes: a mounting plate 50, on which at least a portion of the first driving part 21 and at least a portion of the second driving part 23 are movably disposed; and a guide assembly 60, on which the mounting plate 50 is movably disposed, and the guide assembly 60 and the mounting plate 50 have mutually cooperating guide structures. In this application, the mounting plate 50 and the guide assembly 60 may have mutually cooperating guide rails and guide rail grooves, thereby ensuring that the mounting plate 50 can move in a preset direction. Furthermore, a cylinder for driving the movement of the mounting plate 50 may also be provided on the guide assembly 60.

[0037] Optionally, the injection hole positioning device further includes at least one second driving component 70. The second driving component 70 is disposed on the side of the clamping component 10 away from the first driving component 20 and drives the clamping component 10 to move in a direction closer to or away from the first driving component 20. By providing the second driving component 70, it can be ensured that the clamping component 10 can cooperate with the first driving component 20 more quickly. Of course, in this application, the second driving component 70 may not be provided. In this case, only the second driving part 23 of the first driving component 20 can drive the first driving part 21 and the transmission member 22 to move in a direction closer to or away from the clamping component 10.

[0038] Optionally, the injection hole positioning device further includes a first mounting bracket 80, with the clamping assembly 10 and the second driving assembly 70 respectively disposed on the first mounting bracket 80. Of course, in this application, the first mounting bracket 80 can also be disposed on other structures, thereby ensuring that the first mounting bracket 80 can drive the clamping assembly 10 along the thickness direction of the battery or... Figure 1 and Figure 2 The vertical movement ensures that the transmission component 22 can be aligned with and enter the second opening 112 to drive the clamping component 12 to rotate. Alternatively, in this application, the position of the first mounting bracket 80 is adjustable in the height direction, or the relative position between the first mounting bracket 80 and the first drive assembly 20 is adjustable.

[0039] Optionally, the second detection component 40 is located on the side of the first detection component 30 away from the clamping component 10. Of course, the relative positions of the first detection component 30 and the second detection component 40 can also be adaptively adjusted according to actual usage requirements.

[0040] Optionally, the injection hole positioning device further includes a second mounting bracket 90, a third drive unit 100, and a third mounting bracket 200. The third drive unit 100 is disposed on the second mounting bracket 90; the first detection component 30 and the second detection component 40 are respectively disposed on the third mounting bracket 200, and the third drive unit 100 is drivenly connected to the third mounting bracket 200 so that the first detection component 30 can move in a direction close to or away from the clamping component 10.

[0041] Furthermore, in one specific embodiment of this application, there are four clamping parts, meaning the clamping assembly 10 can clamp four batteries simultaneously, while there can be two first driving assemblies 20. Both first driving assemblies 20 are mounted on the mounting plate 50, and the arrangement direction of the four clamping parts is the same as the arrangement direction of the two first driving assemblies 20. The mounting plate 50 can drive the first driving assemblies 20 to move along the arrangement direction of the four clamping parts. In the arrangement direction of the four clamping parts, the two first driving assemblies 20 can first drive the first and third clamping parts, and then drive the second and fourth clamping parts by moving the first driving assemblies 20 through the mounting plate 50. At this time, there are also four first detection assemblies 30 and two second detection assemblies 40, each corresponding to a battery in one of the four clamping parts. In this embodiment, the two first driving assemblies 20 can share one second driving part 23.

[0042] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0043] 1. Effectively solves the problem of finding battery injection holes efficiently and at low cost in existing technologies;

[0044] 2. Simple structure and stable performance.

[0045] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0046] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0047] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
