Abstract
Description
Technical Field
[0001] This application relates to a battery probe module, and more particularly to a battery probe module that allows the probe to deflect slightly. Background Technology
[0002] Generally, when performing electrical tests on a batch of batteries, multiple batteries must first be placed on a carrier tray, and the tray must be aligned with the battery probe module before the tray can be moved closer to the module. However, for ease of quick battery replacement or other practical reasons, these batteries are usually not securely fixed in the tray. For example, the tray may have multiple battery slots, with each battery designed to fit in one slot. However, since the diameter of the slot is often larger than the diameter of the battery, the battery may shift or wobble slightly within the slot. In other words, each battery may not actually be precisely centered in the slot, and during tray handling, vibrations may cause the battery to press against one side of the slot, resulting in significant differences in the distance between the battery and the inside of the slot in different directions.
[0003] In other words, although the carrier tray and battery probe module undergo an alignment process, each battery in the carrier tray can still move slightly within the battery slot. Therefore, when multiple probes in the battery probe module press against the battery electrodes, the battery electrodes may not effectively contact all the probes. Furthermore, if the battery is already misaligned in the battery slot, the electrodes may be scratched by the probes due to misalignment during the subsequent pressing of multiple probes against the battery electrodes, and the probes may also be damaged by the misaligned battery. On the other hand, in traditional battery probe modules, multiple probes of different polarities often contact their corresponding electrodes in different directions; for example, the positive probe contacts the positive electrode from top to bottom, and the negative probe contacts the negative electrode from bottom to top. Those skilled in the art will understand that when multiple probes push against the battery in different directions, it may cause unexpected shaking or misalignment of the battery, thus preventing the battery electrodes from effectively contacting all the probes. Therefore, the industry needs a new battery probe module that can overcome the problem of battery displacement or misalignment within the battery slot, thereby ensuring effective contact between the battery electrodes and the probes. Summary of the Invention
[0004] The technical problem this application aims to solve is to provide a battery probe module with a tiltable base, thereby allowing probes disposed in the base to be elastically aligned with displaced or misaligned battery electrodes. Furthermore, the battery probe module has probes of different polarities facing the same contact surface, which also avoids unexpected shaking or tilting of the battery caused by probes of different directions pushing against different sides of the battery.
[0005] This application proposes a battery probe module for detecting batteries. The battery has a contact surface, which is divided into a first electrode region and a second electrode region of different polarities. The battery probe module includes a frame and multiple probe units. The frame has a top plate and a bottom plate. Each probe unit includes a base, a first probe, and multiple second probes. The base has a top surface and a bottom surface, and the top surface has a fixing unit that is obliquely fixed to the bottom plate. The first probe is disposed on the base and protrudes from the bottom surface to contact the first electrode region. The multiple second probes are disposed on the base and protrude from the bottom surface to contact the second electrode region. In the vertical direction perpendicular to the bottom surface, the first probe is within the perimeter surrounded by the multiple second probes.
[0006] In some embodiments, the fixing unit may include a fixing member, a spacer, and a clamping block. The spacer may be annular and disposed in a fixing hole in the base plate. The clamping block and the base may be located on opposite sides of the base plate. The fixing member may sequentially pass through the clamping block and the spacer in the vertical direction and be fixed to the base. Furthermore, the clamping block may have a first hole, the base may have a second hole, and the fixing member may pass through the first hole in the vertical direction and be fixed in the second hole. The fixing member and the first hole are in a clearance fit, and the fixing member and the spacer and the second hole are in an interference fit, respectively.
[0007] In some embodiments, the top plate may be provided with multiple ventilation ducts, each corresponding to one of the multiple probe units, and each ventilation duct blows airflow toward the corresponding top surface. The base may be a hollow structure, and the hollow structure connects the top and bottom surfaces of the base. Furthermore, each ventilation duct may be electrically connected to a temperature adjustment unit, which can adjust the airflow rate or airflow temperature through the corresponding ventilation duct based on the temperature of the contact surface, the first probe, or the multiple second probes. Additionally, the bottom surface may be provided with multiple guide members, each guide member protruding from the bottom surface and potentially having a conical end for contacting the edge of the battery casing. Also, the first end face of the first probe and the second end face of each second probe may face the same direction.
[0008] In summary, the battery probe module provided in this application, through its tiltable base, elastically aligns with displaced or misaligned battery electrodes, thereby improving the contact efficiency between the battery electrodes and the probes. Furthermore, since probes of different polarities in the battery probe module all face the same contact surface, it solves the problem of unexpected shaking or misalignment caused by multiple probes pushing in different directions, which also improves the contact efficiency between the battery electrodes and the probes.

[0035] In the embodiments described below, the positional relationships include: up, down, left, and right. Unless otherwise specified, they are all based on the direction shown by the components in the diagram.
[0036] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a perspective view of a battery probe module according to an embodiment of this application. Figure 2 This is a perspective view of a battery probe module according to an embodiment of this application after removing the side cover. As shown, the battery probe module 1 has a frame 10 and multiple probe units 12 for detecting one or more batteries (not shown). In practice, when testing batteries in batches, multiple batteries can be placed regularly in a carrier tray (not shown). For example, the carrier tray can have battery slots arranged in an array, and each battery can be placed in one battery slot. Next, the battery probe module 1 and the carrier tray can be vertically aligned, and after alignment, the carrier tray can be vertically raised to approach the battery probe module 1. Of course, this embodiment does not limit the vertically raised carrier tray or battery probe module 1; those skilled in the art can choose to move the carrier tray or battery probe module 1 depending on the different testing equipment. This embodiment does not limit the appearance and size of the battery. In one example, the battery can be packaged into a near-cylinder shape, and the top of the cylinder can be defined as a contact surface, which can be divided into a first electrode area and a second electrode area of different polarities (positive and negative polarities). For example, the first electrode region and the second electrode region can be two concentric circles, with the first electrode region located inside the second electrode region.
[0037] Following the above, in a practical example, the central position of the contact surface can be the first electrode region (corresponding to the positive electrode), and the edge position of the contact surface can be the second electrode region (corresponding to the negative electrode). Those skilled in the art will understand that there should be an insulating region between the first and second electrode regions, and the first, insulating, and second electrode regions can be three concentric circles. In one example, counting from the center of the concentric circles, the first electrode region, insulating region, and second electrode region are sequentially arranged from the inside out, with the second electrode region precisely covering the edge of the contact surface. Assuming the first electrode region is positive and the second electrode region is negative, this embodiment does not limit the equipotential range of the negative polarity; it is possible that the side of the battery (the side of the cylinder) also has the same polarity (negative polarity) as the second electrode region. It is worth noting that the contact surface (the top of the cylinder) may not be flat; for example, the first electrode region may have a height difference with the second electrode region. However, as long as the normal directions of the first and second electrode regions are the same, the first and second electrode regions still belong to the contact surface defined in this embodiment.
[0038] As shown in the figure, the frame 10 can be a hollow box with a top plate 100 and a bottom plate 102 on opposite sides. To illustrate the internal structure of the frame 10, this embodiment will... Figure 1 After the side cover 10a between the top plate 100 and the bottom plate 102 is removed, it can be seen from Figure 2 The relative positions of the top plate 100 and the bottom plate 102 are observed. In practice, the top plate 100 and the bottom plate 102 are located on the upper and lower sides of the frame 10, respectively, and both the top plate 100 and the bottom plate 102 have openings, while the interior of the frame 10 can have space to accommodate other components. In one example, multiple probe units 12 are disposed on the bottom plate 102, while the top plate 100 may have multiple ventilation pipes 104. The multiple ventilation pipes 104 are connected to an external air conditioning unit (not shown) to deliver airflow. Although Figure 2 This embodiment does not contain multiple ventilation ducts 104 outside the frame 10. However, those skilled in the art will understand that the multiple ventilation ducts 104 can each be connected to an independent air conditioning unit, or the multiple ventilation ducts 104 can be connected to each other by a larger duct, and then connected to the same air conditioning unit. This embodiment is not limited to this. Furthermore, the number of ventilation ducts 104 can correspond to the number of probe units 12, and the air outlet of each ventilation duct 104 can be aligned with the probe unit 12 vertically downwards.
[0039] In one example, the airflow rate or airflow temperature delivered by each ventilation duct 104 is adjustable. For instance, when multiple ventilation ducts 104 are connected to the same air conditioning unit, assuming that the diameter, length, or material of each ventilation duct 104 is approximately the same, the airflow rate and airflow temperature delivered by each ventilation duct 104 should also be approximately the same. Therefore, in this embodiment, the airflow rate or airflow temperature delivered by each ventilation duct 104 can be determined by setting the total airflow rate output by the external air conditioning unit and controlling the output airflow temperature. As another example, when each ventilation duct 104 is connected to its respective air conditioning unit, this embodiment can directly control the airflow rate and airflow temperature provided by each respective air conditioning unit, thus determining the airflow rate or airflow temperature delivered by the connected ventilation ducts 104.
[0040] It is worth noting that even if multiple ventilation ducts 104 are connected to the same air conditioning unit, the airflow and air temperature delivered by each ventilation duct 104 may differ. In one example, each ventilation duct 104 may have an internal fan (not shown), and the fan may be controlled by a temperature adjustment unit (not shown). When the temperature adjustment unit determines that the corresponding probe unit 12 of the ventilation duct 104 needs cooling, it can control the fan speed to increase the airflow of the ventilation duct 104. When the temperature adjustment unit determines that the corresponding probe unit 12 needs heating, it can control the fan speed to decrease the airflow of the ventilation duct 104. As can be seen from the above examples, this embodiment can achieve individualized temperature control for each probe unit 12. Furthermore, the piping of the ventilation ducts 104 within the frame 10 can be... Figure 2 Yes, it can be longer. For example, the ventilation duct 104 can extend further towards the probe unit 12, which not only avoids airflow interference between adjacent ventilation ducts 104, but also provides better temperature control for the probe unit 12. This embodiment does not limit the diameter, length, or material of the ventilation duct 104, and those skilled in the art can choose accordingly.
[0041] For ease of presentation in the drawings, this embodiment will... Figure 2 The frame 10 and probe unit 12 are described separately. Please refer to both. Figures 2 to 6 , Figure 3 This is a perspective view of a frame according to an embodiment of this application. Figure 4 This is a perspective view of a probe unit according to an embodiment of this application. Figure 5 This is a perspective view of a probe unit according to an embodiment of this application from another angle. Figure 6This is an exploded view of a probe unit according to an embodiment of this application. As shown, the top plate 100 of the frame 10 may have holes 1000, and each ventilation pipe 104 may pass through the hole 1000 and extend into the interior space of the frame 10. For example, the ventilation pipe 104 may extend a certain length into the interior space of the frame 10 towards the bottom plate 102. The bottom plate 102 of the frame 10 may also have multiple holes 1020 and multiple fixing holes 1022. In the figure, one hole 1020 and multiple fixing holes 1022 arranged around the hole 1020 may correspond to the same probe unit 12. For example, the central axis of the hole 1020 may exactly overlap with the central axis of the base 120 of the probe unit 12. In practice, the hole 1020 can allow airflow from the ventilation pipe 104 to pass through, so that the airflow blown out by the ventilation pipe 104 can directly blow towards the base 120. The hole 1020 may also accommodate the wires used to connect the corresponding probe unit 12. In addition, the fixing holes 1022 arranged around the hole 1020 can be used to fix the base 120 of the probe unit 12.
[0042] The multiple probe units 12 demonstrated in this embodiment may be identical; the following description and demonstration will use one of the probe units 12. As shown in the figure, the probe unit 12 has a base 120, a first probe 122, and multiple second probes 124. The base 120 is defined with a top surface 120a and a bottom surface 120b. The first probe 122 and the multiple second probes 124 are disposed on the base 120 and protrude from the bottom surface 120b. In practice, the base 120 has a hollow structure; for example, the hollow structure may consist of one or more hollow holes 120c. Therefore, the hollow structure connects the top surface 120a and the bottom surface 120b of the base 120, allowing the airflow from the ventilation pipe 104 to easily pass through the entire base 120. In one example, the airflow from the ventilation pipe 104 can directly pass over the entire first probe 122 and each of the second probes 124, and the airflow can even easily reach the battery contact surface. In addition, the hollow structure of the base 120 can also hollow out the sides of the base 120 other than the top surface 120a and bottom surface 120b, so that the base 120 can be lightweight and the heat dissipation effect of the first probe 122 and multiple second probes 124 can be improved.
[0043] In the aforementioned example, each ventilation duct 104 may contain a fan (not shown), and the fan may be controlled by a temperature adjustment unit (not shown). Here, the temperature adjustment unit can determine whether the battery contact surface needs to be heated or cooled by placing a temperature sensing wire near the battery contact surface (e.g., attached to the first probe 122 or one of the second probes 124). The means of heating or cooling the battery contact surface have been demonstrated in the aforementioned embodiment and will not be repeated in this embodiment.
[0044] Furthermore, the first probe 122 and the plurality of second probes 124 are used for battery detection. For example, during electrical testing, the first probe 122 and the plurality of second probes 124 can supply power to the battery or can be used to detect the battery's voltage or current. Additionally, the plurality of second probes 124 are distributed around the first probe 122, in a direction perpendicular to the bottom surface 120b (e.g., the normal direction of the bottom surface 120b), with the first probe 122 within the perimeter formed by the plurality of second probes 124. In this embodiment, after alignment, the carrier tray moves the battery to be tested below the probe unit 12, so that the battery's contact surface is adjacent to the first probe 122 and the plurality of second probes 124. As the carrier tray supports the battery and rises, the first probe 122 gradually contacts and presses against the first electrode region (not shown), and the plurality of second probes 124 gradually contacts and presses against the second electrode region (not shown). The advantage is that, since the first probe 122 and the plurality of second probes 124 are in the same direction, especially the first end face 122a of the first probe 122 and the second end face 124a of the second probe 124 face the same direction, for example, towards the downward battery contact surface. That is to say, in this embodiment, the probes of different polarities (the first probe 122 and the plurality of second probes 124) all extend downward. The first probe 122 is used to press downward against the center of the battery contact surface (the first electrode region), and the plurality of second probes 124 press downward evenly against the edge of the battery contact surface (the second electrode region).
[0045] In one example, the base 120 may also have multiple guides 126 disposed on the bottom surface 120b, with the first probe 122, multiple second probes 124, and multiple guides 126 oriented in the same direction. In practice, the multiple guides 126 protrude further from the bottom surface 120b than the first probe 122 and multiple second probes 124. This is to ensure that when the carrier plate supports the battery and rises, the multiple guides 126 can contact the corresponding battery first and restrict the battery's position, allowing the first probe 122 to be correctly aligned with the first electrode area and the multiple second probes 124 to be correctly aligned with the second electrode area. Although this embodiment has one guide 126 at each of the four corners of the bottom surface 120b of the base 120, this embodiment does not limit the number or shape of the guides 126. Any guide 126 that can guide the battery and restrict its position should be considered a guide 126 as described in this embodiment. For example, there could be only three guides arranged in a triangle. Alternatively, the guides could be changed to a ring shape and surround the first probe 122 and multiple second probes 124. As long as the ends of the guides still have an annular bevel facing the center of the bottom surface 120b, the purpose of limiting the position of the battery should be achieved.
[0046] Here, each guide member 126 may have a conical end 126a. Because the end 126a has an arcuate surface, even if the battery is initially slightly offset in the battery slot of the carrier, after the multiple guide members 126 contact the battery, as the battery rises, the battery can be pushed synchronously to adjust its position in the battery slot. Furthermore, the end 126a generally contacts the edge of the battery casing and moves the battery by pushing against the edge of the battery casing. For example, assuming the battery is cylindrical, the uppermost plane of the cylinder can be the contact surface as referred to in this embodiment, and the junction of the arcuate side of the cylinder and the contact surface can be the casing edge as referred to in this embodiment. Those skilled in the art will understand that, although the diameter of the battery slot and the diameter of the battery differ, the battery can usually only wobble slightly, so when the battery is placed in the battery slot and slightly offset, it should not be too far from its default position. Therefore, when the carrier plate supports the battery and rises upward, the end 126a of each guide 126 should contact the edge of the outer casing, rather than directly piercing the contact surface.
[0047] Unlike traditional probes of different polarities that push the battery in different directions, the probes in this embodiment all contact the same side of the battery. This not only avoids different stress directions from multiple probes pushing the battery, reducing the likelihood of unexpected shaking or tilting, but also, because the battery's contact surface is below the first probe 122 and the plurality of second probes 124, it can push the battery towards the carrier, stabilizing it in the carrier below. Therefore, since the first probe 122 and the plurality of second probes 124 are in the same direction, this embodiment can improve the contact stability between the battery electrodes and the first probe 122 and the plurality of second probes 124, reducing the possibility that the first probe 122 and the plurality of second probes 124 may not fully contact the electrodes.
[0048] As will be understood by those skilled in the art, the correct contact (fitting contact) of the first probe 122 with the first electrode region indicates a larger contact area between the first probe 122 and the first electrode region, thus reducing the impedance between them. Similarly, the more second probes 124 that can correctly contact (fitting contact) the second electrode region, the larger the total contact area between the multiple second probes 124 and the second electrode region, thus reducing the impedance between the multiple second probes 124 and the second electrode region. In this way, when the impedance between the probes and the battery electrodes provided in this embodiment is reduced, the heating of the battery contact surface can be improved. This not only allows the probes to more accurately detect the battery's electrical parameters, but also enables effective temperature control of the battery contact surface.
[0049] Please continue referring to the figures. The top surface 120a of the base 120 is provided with a fixing unit 128, which may include a fixing member 1280, a spacer 1282, and a clamping block 1284. As shown in the figure, the probe unit 12 and the fixing unit 128 can be in a one-to-one relationship, that is, the probe unit 12 can be obliquely fixed to the base plate 102 through the corresponding fixing unit 128. Here, this embodiment does not limit the number of fixing members 1280, spacers 1282, and clamping blocks 1284. The number of fixing members 1280 and spacers 1282 can be related to the number of fixing holes 1022 arranged in the same group (corresponding to the same probe unit 12) around the hole 1020. As shown in the figure, the clamping block 1284 is in the internal space of the frame 10, and the base 120 is outside the internal space of the frame 10, that is, the base 120 and the clamping block 1284 are respectively on both sides of the base plate 102. In one example, the central position of the clamping block 1284 may have a hole 1284a and a plurality of first holes 1284b arranged around the hole 1284a. Here, the arrangement of the hole 1284a and the first holes 1284b may be the same as the arrangement of the hole 1020 and the fixing hole 1022.
[0050] In other words, although the clamping block 1284 is above the base plate 102, the gas blown out by the ventilation pipe 104 can still pass through the clamping block 1284 and the base plate 102 through the corresponding holes 1020 and 1284a. In one example, the first probe 122 and a plurality of second probes 124 are electrically connected to an external testing machine (not shown) via wires. Through the corresponding holes 1020 and 1284a, the wires used by the first probe 122 and the plurality of second probes 124 can also pass through the clamping block 1284 and the base plate 102 and be housed in the internal space of the frame 10. Furthermore, the fastener 1280 can be a screw or a nail, and the clamping block 1284 has a first hole 1284b, and the base 120 has a second hole 120d. When each fastener 1280 passes through the first hole 1284b of the clamping block 1284, the fixing hole 1022 of the base plate 102, and the second hole 120d of the seat 120 in sequence, the seat 120 and the base plate 102 should not have any obvious misalignment or displacement, regardless of whether the fastener 1280 has been locked.
[0051] To illustrate how the base 120 can be obliquely fixed to the base plate 102 via the fixing unit 128, please refer to the following: Figures 2 to 8 . Figure 7 This is a side view of a probe unit according to an embodiment of this application. Figure 8 This is a partially enlarged schematic diagram of a probe unit according to an embodiment of this application. This embodiment is... Figure 7The middle frame selects the area A around one of the fasteners 1280 as an example, where a gap h can be seen between the clamping block 1284 and the top surface 120a of the base 120. Figure 7 The base plate 102 is not explicitly stated; therefore, the gap h refers to the thickness of the base plate 102. In other words, Figure 7 The example simulates the state where the clamping block 1284 and the base 120 clamp the base plate 102; however, it doesn't actually extend beyond the base plate 102. In practice, the diameter of the first hole 1284b of the clamping block 1284 is larger than the diameter of the fastener 1280, and the fastener 1280 will be slightly loose within the first hole 1284b. Figure 8 There will be a clearance w of twice the size of the hole 1284b and the fastener 1280. Based on the above, it will be known to those skilled in the art that the fastener 1280 and the first hole 1284b are in a clearance fit.
[0052] Furthermore, the diameter of the fixing hole 1022 in the base plate 102 is larger than the diameter of the fixing member 1280. To ensure a tighter connection between the fixing member 1280 and the fixing hole 1022, an annular spacer 1282 can be provided in the fixing hole 1022. When the fixing member 1280 passes through the fixing hole 1022, the spacer 1282 will fit over the outside of the fixing member 1280 and abut against the fixing hole 1022, preventing relative movement between the fixing member 1280, the spacer 1282, and the fixing hole 1022. In practice, the diameter of the central opening of the annular spacer 1282 is slightly smaller than the diameter of the fixing member 1280, allowing the spacer 1282 to fit tightly over the fixing member 1280. Additionally, the diameter of the second hole 120d in the seat 120 is also slightly smaller than the diameter of the fixing member 1280, resulting in a better fixing effect after one end of the fixing member 1280 is inserted into the second hole 120d. Based on the above, it is known to those skilled in the art that the fastener 1280 and the spacer 1282, as well as the fastener 1280 and the second hole 120d, are both interference fits.
[0053] Depend on Figure 8It is known that only one end of the fastener 1280 is fixed in the second hole 120d, while the other end of the fastener 1280 is not actually fixed in the clamping block 1284. That is, the other end of the fastener 1280 can wiggle slightly, and the range of wiggle is twice the gap w. However, the fact that the fastener 1280 can wiggle does not mean that the fastener 1280 is not locked. In fact, the fastener 1280 is indeed locked in the second hole 120d, but because the seat 120, spacer 1282, or fastener 1280 are not intentionally made of extremely stiff materials, the seat 120, spacer 1282, or fastener 1280 should be slightly elastic and able to withstand slight compression, allowing the other end of the fastener 1280 to tilt or vibrate within twice the gap w. This embodiment does not limit the length of the fastener 1280, nor does it limit the length of the fastener 1280 fixed in the second hole 120d. As will be understood by those skilled in the art, in order to allow the other end of the fastener 1280 to tilt or vibrate within the 2w gap, the length of the fastener 1280 fixed in the second hole 120d may be less than half or one-third of the total length of the fastener 1280.
[0054] In a practical example, assuming the battery is initially slightly offset (e.g., tilted) in the battery slot of the carrier, in addition to attempting to guide the battery movement using multiple guides 126, the first probe 122 and multiple second probes 124 in the base 120 may also be deflected, allowing the first probe 122 and multiple second probes 124 to make perpendicular contact with the battery's contact surface. In one example, as the battery begins to rise toward the corresponding base 120, the multiple guides 126, the first probe 122, or the multiple second probes 124 will gradually begin to bear stress after contacting the battery. In particular, when the contact surface is tilted due to misalignment of the battery, both the outer casing edge contacted by the multiple guides 126 and the electrode area contacted by the first probe 122 and multiple second probes 124 will bear significant lateral stress in addition to vertical stress. However, since this embodiment demonstrates an example where the fixing member 1280 can be tilted, when the multiple guides 126, the first probe 122, or the multiple second probes 124 are subjected to lateral stress, the seat 120 will also be subjected to lateral stress. At this time, the fixing member 1280, which is already securely locked in the second hole 120d, will also be subjected to lateral stress because it is connected to the seat 120. However, since the other end of the fixing member 1280 can be slightly wobbled, the fixing member 1280 in this embodiment can cause the seat 120 to adaptively shift horizontally or angularly, allowing the lateral stress to be released. Therefore, the first probe 122 and the multiple second probes 124 in this embodiment have the opportunity to adjust the angle of their end faces, so that the first probe 122 and the multiple second probes 124 can return to a situation where they are perpendicular to the contact surface of the battery, further increasing the contact area between the first probe 122 and the multiple second probes 124 and their respective electrode regions.
[0055] In summary, the battery probe module provided in this application, through its tiltable base, elastically aligns with displaced or misaligned battery electrodes, thereby improving the contact efficiency between the battery electrodes and the probes. Furthermore, since probes of different polarities in the battery probe module all face the same contact surface, it solves the problem of unexpected shaking or misalignment caused by multiple probes pushing in different directions, which also improves the contact efficiency between the battery electrodes and the probes.

Any person skilled in the art may make some modifications or alterations to other equivalent embodiments without departing from the scope of the technical means disclosed in this application, but these should still be regarded as the technology or embodiments that are substantially the same as those of this application.
