Description

Technical Field

[0001] The invention relates to the technical field of battery detection, and in particular to a solid-state battery continuous detection device. Background Art

[0002] All-solid-state lithium batteries are energy storage devices that do not contain liquid in their structure and all materials exist in solid form, relative to liquid lithium batteries. After production, solid-state batteries need to be tested, such as testing the heat generation of solid-state batteries under different resistance support states, in order to ensure the quality of the solid-state batteries after production.

[0003] After searching, the Chinese utility model patent with publication number CN2154132121U discloses a solid-state battery rapid detection device, which facilitates batch detection of heat generation under load for solid-state batteries through the mutual cooperation of a temperature detector, a battery placement slot, a first metal contact block, a second metal contact block, and a resistor box.

[0004] Although the detection device described in the cited patent can detect solid-state batteries, it lacks the function of continuous detection. After the detection is completed, it is necessary to wait for the solid-state battery after detection to be picked up and a new fixed battery to be detected to be placed, resulting in low work efficiency. In actual implementation, although continuous detection can be achieved by continuously conveying solid-state batteries through a belt conveyor mechanism, it requires good coordination between the belt conveyor mechanism and each detection unit that performs solid-state battery detection, which is often achieved through complex electronic control programs and sensor structures. The arrangement of the electronic control program and the sensor mechanism not only increases the cost of the device, but also makes it easy for electronic control failures to occur, resulting in frequent maintenance of the device. There are problems of high cost and insufficient stability, so it is urgent to solve them. Summary of the invention

When the linear reciprocating mechanism performs the clamping action, the rotation direction of the linkage gear is the working direction, the one-way bearing is locked with the transmission roller in the working direction, and rotates freely around the outer periphery of the transmission roller in the opposite direction of the working direction.

[0009] As a further solution of the present invention: the linear reciprocating mechanism also includes a second rack that can slide along its own length direction, the second rack is meshed with the connecting gear for transmission, the second rack and the first rack are distributed in parallel, and the two are symmetrically arranged on both sides of the connecting gear; the positive electrode plate is installed on the power end of the linear reciprocating mechanism, and the negative electrode plate is installed on the second rack.

[0010] As a further solution of the present invention: the straight-stroke reciprocating mechanism also includes a hydraulic cylinder distributed just above the middle of the conveyor belt, the telescopic end of the hydraulic cylinder telescopes in the vertical direction, and the telescopic end of the hydraulic cylinder is fixed with a lifting seat, and the positive electrode sheet and the first rack are both installed on the lifting seat; the inner cavity of the conveyor belt is a triangular structure with a convex middle part, and the transmission rollers are arranged in three groups distributed at the three corners of the triangular structure, and the transmission rollers protruding from the middle part are dynamically coordinated with the straight-stroke reciprocating mechanism, the negative electrode sheet is located in the inner cavity of the conveyor belt, and a soft metal sheet that passes through the conveyor belt is arranged on the solid-state battery placement area, and when the negative electrode sheet performs the clamping action, it abuts against the soft metal sheet located in the detection area to conduct electricity.

[0011] As a further solution of the present invention: a mounting frame is installed on the supporting body of the belt conveyor mechanism, the hydraulic cylinder is fixed on the mounting frame, and the height of the mounting frame is adjustable or the height of the positive electrode sheet on the lifting seat is adjustable.

[0012] As a further solution of the present invention: a resistance box connected in series with the positive electrode sheet is arranged on the lifting seat.

[0013] As a further solution of the present invention: a lower base is fixed on the second rack, and the negative electrode sheet is slidably matched with the lower base through a vertically distributed sliding rod, and a buffer spring is sleeved on the sliding rod to elastically press the negative electrode sheet upward.

[0014] As a further solution of the present invention: the temperature detection mechanism includes a temperature measurement module distributed beside the detection area, and the temperature measurement module can be horizontally adjusted along a direction perpendicular to the conveying direction of the solid-state battery.

[0015] As a further solution of the present invention: the temperature detection mechanism includes a slide that can slide horizontally perpendicular to the conveying direction of the solid-state battery, the temperature measurement module is installed on the slide, and a wedge block that cooperates with the oblique wedge of the slide is fixed on the second rack. The slide cooperates with the oblique wedge of the wedge block, and when the second rack moves upward or downward, the slide is driven to approach or move away from the detection area respectively.

[0016] As a further solution of the present invention: the temperature measuring module is connected to the slide seat through a telescopic rod, the telescopic rod is arranged along the sliding direction of the slide seat, and a compression spring is sleeved on the telescopic rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the straight-stroke reciprocating mechanism performs the clamping action, the transmission roller of the belt conveyor mechanism is driven to rotate through the one-way linkage mechanism, thereby driving the conveyor belt to rotate, driving the solid-state battery on the solid-state battery placement area upstream of the adjacent detection area to be transported to the detection area, and finally the solid-state battery entering the detection area is electrically connected with the negative electrode sheet and the positive electrode sheet that perform the clamping action, thereby the solid-state battery entering the detection area can be tested. After the detection is completed, the straight-stroke reciprocating mechanism performs the separation action. Since the one-way linkage mechanism only forms a power match with the transmission roller when the straight-stroke reciprocating mechanism performs the clamping action, when the straight-stroke reciprocating mechanism performs the separation action, only the negative electrode sheet and the positive electrode sheet are disconnected from the solid-state battery, and the conveyor belt remains stationary; the straight-stroke reciprocating mechanism performs the clamping action again, and the above process is repeated to transport the solid-state battery on the solid-state battery placement area upstream of the adjacent detection area to the detection area. Therefore, a reciprocating cycle motion is performed in the straight-stroke reciprocating mechanism to perform a separation action and a clamping action respectively, that is, to complete the detection of a group of solid-state batteries. As the linear reciprocating power mechanism continues to perform reciprocating periodic motion, continuous detection operations on solid-state batteries can be achieved. There is no need to set up complex electronic control programs and sensor mechanisms, and stable continuous detection operations on solid-state batteries can be achieved, which not only reduces the cost of the device but also ensures the stability of the device movement.

[0019] 2. The one-way linkage mechanism includes a linkage gear rotatably engaged with the transmission roller through a one-way bearing, and a first rack meshing with the linkage gear is connected to the power end of the linear reciprocating mechanism; when the linear reciprocating mechanism performs a clamping action, the rotation direction of the linkage gear is the working direction, and the one-way bearing is locked with the transmission roller in the working direction. At this time, when the first rack drives the linkage gear to rotate, it can synchronously drive the transmission roller to rotate; the one-way bearing rotates freely around the outer periphery of the transmission roller in the opposite direction of the working direction, that is, when the linear reciprocating mechanism performs a phase separation action, driving the first rack to drive the linkage gear to rotate will not drive the transmission roller to rotate synchronously, thereby achieving the above-mentioned one-way linkage mechanism only forms a power match with the transmission roller when the linear reciprocating mechanism performs a clamping action, and has the advantages of simple structure and stable function.

[0020] 3. Install the positive electrode sheet on the power end of the linear reciprocating mechanism and the negative electrode sheet on the second rack, so that the positive electrode sheet and the negative electrode sheet synchronously slide in opposite directions, that is, the positive electrode sheet and the negative electrode sheet move away from each other to achieve a separation action, and the positive electrode sheet and the negative electrode sheet move close to each other to achieve a clamping action, so that the positive electrode sheet and the negative electrode sheet can move synchronously to achieve the clamping action and the separation action without setting up an additional power source.

[0021] 4. The clamping method of sliding the positive and negative plates up and down not only reduces the horizontal space occupied by the device, but also, when the solid-state battery is in the initial state of placement, the negative electrode of the solid-state battery is positioned and abutted against the soft metal sheet that forms the conductive negative electrode, ensuring that the solid-state battery can form a stable conductive state during testing.

[0022] 5. By establishing power transmission between the temperature measuring module and the linear reciprocating mechanism, when the linear reciprocating mechanism performs a clamping action or an unlocking action, the temperature measuring module is respectively moved close to or away from the solid-state battery. Stable coordination between the temperature detection mechanism and the power supply mechanism can be achieved without an additional power source, thereby ensuring the accuracy of stable detection of the temperature measuring module during the detection process.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] For ease of understanding, the specific structure and working mode of the present invention are further described below in conjunction with the accompanying drawings:

[0031] The specific structure of the present invention refers to Figure 1-5 As shown, its main structure includes a belt conveyor mechanism 10 for conveying solid-state batteries, a power supply mechanism 20 for supplying power to the solid-state batteries, and a temperature detection mechanism 30 for detecting the temperature of the solid-state batteries.

[0032] Among them, Figure 1 and Figure 3 As shown, the power supply mechanism 20 includes a negative electrode sheet 24 and a positive electrode sheet 28 arranged at intervals, and the interval between the negative electrode sheet 24 and the positive electrode sheet 28 forms a detection area for accommodating the solid-state battery to pass through. When working, the belt conveyor mechanism 10 will sequentially convey the solid-state battery to the detection area for power supply, and perform temperature detection through the temperature detection mechanism 30 in the detection area. Specifically, the negative electrode sheet 24 and / or the positive electrode sheet 28 are driven to move by a linear reciprocating mechanism, and the negative electrode sheet 24 and the positive electrode sheet 28 are separated and clamped; when the solid-state battery is conveyed to the detection area, the negative electrode sheet 24 and the positive electrode sheet 28 are clamped, and the negative electrode and the positive electrode of the solid-state battery in the detection area are respectively abutted to form an electrical connection. At this time, the temperature detection operation of the solid-state battery can be performed by the temperature detection mechanism 30. When the temperature detection mechanism 30 completes the detection, the negative electrode sheet 24 and the positive electrode sheet 28 are separated. At this time, the solid-state battery that has been detected can be transported outside the detection area.

[0033] On the basis of the above, if Figure 1-3As shown, the outer periphery of the conveyor belt 11 of the belt conveyor mechanism 10 is equidistantly divided into several solid-state battery placement areas, and the linear reciprocating mechanism forms a power match with the drive roller 12 of the belt conveyor mechanism 10 through the one-way linkage mechanism 13, and the one-way linkage mechanism 13 drives the drive roller 12 to rotate only when the linear reciprocating mechanism performs a clamping action, and makes the adjacent solid-state battery placement areas move to the detection area in sequence. When in use, along the solid-state battery conveying direction, the solid-state battery is placed in the fixed battery placement area located upstream of the detection area. When the linear reciprocating mechanism performs a clamping action, the one-way linkage mechanism 13 drives the drive roller 12 of the belt conveyor mechanism 10 to rotate, thereby driving the conveyor belt 11 to rotate, driving the solid-state battery on the solid-state battery placement area upstream of the adjacent detection area to be transported to the detection area, and finally making the solid-state battery entering the detection area form an electrical connection with the negative electrode sheet 24 and the positive electrode sheet 28 that perform the clamping action, thereby the solid-state battery entering the detection area can be tested. When the detection is completed, the straight-stroke reciprocating mechanism performs a separation action. Since the one-way linkage mechanism 13 forms a power coordination with the drive roller 12 only when the straight-stroke reciprocating mechanism performs a clamping action, when the straight-stroke reciprocating mechanism performs a separation action, only the negative electrode sheet 24 and the positive electrode sheet 28 are disconnected from the solid-state battery, and the conveyor belt 11 remains stationary. The straight-stroke reciprocating mechanism performs a clamping action again, and the above process is repeated to transport the solid-state batteries on the solid-state battery placement area upstream of the adjacent detection area to the detection area. Therefore, a reciprocating cycle motion is performed in the straight-stroke reciprocating mechanism to perform a separation action and a clamping action respectively, that is, to complete the detection of a group of solid-state batteries. As the straight-stroke reciprocating power mechanism continues to perform a reciprocating cycle motion, the continuous detection operation of the solid-state battery can be realized. There is no need to set up a complex electronic control program and a sensor mechanism, and the stable continuous detection operation of the solid-state battery can be realized, which not only reduces the cost of the device but also ensures the stability of the device movement.

[0034] On the basis of the above, if Figure 2 As shown, the one-way linkage mechanism 13 includes a linkage gear 132 that is rotatably engaged with the transmission roller 12 through a one-way bearing 131, and a first rack 25 that meshes with the linkage gear 132 is connected to the power end of the linear reciprocating mechanism; when the linear reciprocating mechanism performs a clamping action, the rotation direction of the linkage gear 132 is the working direction, and the one-way bearing 131 is locked with the transmission roller 12 in the working direction. At this time, when the first rack 25 drives the linkage gear 132 to rotate, it can synchronously drive the transmission roller 12 to rotate; the one-way bearing 131 rotates freely around the outer periphery of the transmission roller 12 in the opposite direction of the working direction, that is, when the linear reciprocating mechanism performs a phase separation action, when the first rack 25 drives the linkage gear 132 to rotate, it will not drive the transmission roller 12 to rotate synchronously, thereby realizing that the above-mentioned one-way linkage mechanism 13 only forms a power match with the transmission roller 12 when the linear reciprocating mechanism performs a clamping action, and has the advantages of simple structure and stable function.

[0035] In actual implementation, the one-way linkage mechanism 13 may also have other implementations, such as a ratchet is provided on the driving roller 12, and inner ratchets coaxially spaced and distributed on the outer periphery of the driving roller 12 to cooperate with the ratchet, and a toothed ring is fixed on the outer periphery of the inner ratchet, and the toothed ring is meshed with the first rack 25 for transmission, which can also achieve the effect of the above-mentioned one-way bearing 131. In addition, the meshing teeth on the first rack 25 may also adopt a structure similar to a ratchet, which can mesh with the linkage gear 132 during the sliding process of performing the clamping action, but cannot mesh with the linkage gear 132 during the sliding process of performing the separation action.

[0036] On the basis of the above, if Figure 2 and Figure 3 As shown, the linear reciprocating mechanism also includes a second rack 26 that can slide along its own length direction. Specifically, the second rack 26 can be slidably matched with the supporting body of the belt conveyor mechanism 10, or can be slidably matched on a slide rail fixed to the ground. The second rack 26 is meshed with the linkage gear 132 for transmission. The second rack 26 and the first rack 25 are distributed in parallel, and the two are symmetrically arranged on both sides of the linkage gear 132. When the first rack 25 slides toward one end and meshes with the linkage gear 132, the second rack 26 meshes with the linkage gear 132 and slides in the opposite direction of the sliding of the first rack 25. In this embodiment, the positive electrode sheet 28 is installed on the power end of the linear reciprocating mechanism, and the negative electrode sheet 24 is installed on the second rack 26, so that the positive electrode sheet 28 and the negative electrode sheet 24 are synchronously sliding in opposite directions, that is, the positive electrode sheet 28 and the negative electrode sheet 24 are moved away from each other to achieve a separation action, that is, the positive electrode sheet 28 and the negative electrode sheet 24 are moved close to each other to achieve a clamping action, so that there is no need to set up an additional power source, and the positive electrode sheet 28 and the negative electrode sheet 24 can move synchronously to achieve a clamping action and a separation action. Of course, in actual implementation, only the positive electrode sheet 28 can be driven to slide with the linear reciprocating mechanism, while the negative electrode sheet 24 is fixed, and the clamping action and the separation action can be respectively achieved by the positive electrode sheet 28 approaching or moving away from the negative electrode sheet 24. Similarly, the positive electrode sheet 28 can be fixed, and the negative electrode sheet 24 can be driven to slide with the linear reciprocating mechanism. Of course, the single positive electrode sheet 28 or negative electrode sheet 24 slides in a relatively low efficiency in clamping and separation action. In addition, higher requirements are placed on the driving stroke of the linear reciprocating mechanism and on the placement accuracy of the solid-state battery.

[0037] Based on the synchronous movement of the positive electrode sheet 28 and the negative electrode sheet 24 toward or away from each other, as shown in FIG. Figure 1 and Figure 3As shown, the linear reciprocating mechanism also includes a hydraulic cylinder 22 distributed just above the middle of the conveyor belt 11, the telescopic end of the hydraulic cylinder 22 telescopes in the vertical direction, and a lifting seat 221 is fixed to the telescopic end of the hydraulic cylinder 22, and the positive electrode sheet 28 and the first rack 25 are both installed on the lifting seat 221, so that the positive electrode sheet 28 and the negative electrode sheet 24 both adopt a vertical sliding action mode. The inner cavity of the conveyor belt 11 is a triangular structure with a downward protrusion in the middle, and the driving rollers 12 are arranged in three groups distributed at the three corners of the triangular structure, and the driving rollers 12 protruding in the middle cooperate with the linear reciprocating mechanism; the negative electrode sheet 24 is located in the inner cavity of the conveyor belt 11, and a soft metal sheet 111 that penetrates the conveyor belt 11 is arranged on the solid-state battery placement area, and when the negative electrode sheet 24 is clamped, it contacts the soft metal sheet 111 located in the detection area for electrical conduction, and the soft metal sheet 111 contacting the negative electrode sheet 24 is used as a conductive negative electrode. When in use, the negative pole of the solid-state battery is placed downward on the soft metal sheet 111 on the solid-state battery placement area. After the soft metal sheet 111 moves to the detection area, the negative pole sheet 24 moves upward to abut against the soft metal sheet 111 for conduction, and the positive pole sheet 28 moves downward to abut against the upper positive pole of the solid-state battery for conduction, thereby forming a power supply for the solid-state battery. The clamping method of the positive pole sheet 28 and the negative pole sheet 24 sliding up and down not only reduces the horizontal space occupied by the device, but also, in the initial state of the solid-state battery, the negative pole of the solid-state battery is positioned and abutted against the soft metal sheet 111 forming the conductive negative pole, ensuring that the solid-state battery can form a stable conductive state during detection. Of course, in actual implementation, if the solid-state battery can be placed more stably with the positive pole facing downward, the negative pole sheet 24 can be arranged above and the positive pole sheet 28 can be arranged below. In addition, the hydraulic cylinder 22 in the linear reciprocating mechanism can also adopt the cylinder, screw slider mechanism, etc. in the prior art.

[0038] It is worth mentioning that if both the positive and negative electrodes of the solid-state battery cannot be stably placed, the positive and negative electrodes of the solid-state battery can be placed on both sides of the conveyor belt 11. At this time, the positive electrode sheet 28 and the negative electrode sheet 24 can be distributed on both sides of the conveyor belt 11. Of course, in this embodiment, the transmission rollers 12 can be set as two groups spaced apart in the horizontal direction, and the driving direction of the linear reciprocating mechanism is changed to be perpendicular to the conveying direction along the conveyor belt 11. At this time, the one-way linkage mechanism 13 also needs to include a gear set that drives the first rack 25. The gear set may include a first gear meshing with the linkage gear 132 and a second gear meshing with the first rack 25. The first gear and the second gear are coaxially fixed with bevel gears that mesh with each other to achieve the linkage between the first rack 25 and the one-way linkage mechanism 13.

[0039] On the basis of the above, if Figure 1 and Figure 3As shown, a mounting frame 21 is installed on the supporting body of the belt conveyor mechanism 10, and a hydraulic cylinder 22 is fixed on the mounting frame 21. The mounting frame 21 is height-adjustable or the height of the positive electrode sheet 28 on the lifting seat 221 is adjustable, so that the present application can be applied to solid-state batteries of different heights. In actual implementation, the height of the mounting frame 21 is adjustable or the height of the positive electrode sheet 28 on the lifting seat 221 is adjustable, and the adjustment structure of the conventional slide rail and slide combined with the set screw or the latch in the prior art can be adopted. In addition, in actual implementation, the positive electrode sheet 28 can also be connected to the lifting seat 221 by a telescopic rod arranged vertically, and the lifting stroke of the positive electrode sheet 28 is greater than the height of the solid-state battery. After the positive electrode sheet 28 abuts against the upper part of the solid-state battery, the telescopic rod shrinks, so as not to hinder the lifting seat 221 from continuing to slide downward, and the telescopic stroke of the telescopic rod serves as the height difference interval of the adapted solid-state battery.

[0040] On the basis of the above, if Figure 3 As shown, a resistor box 23 connected in series with the positive electrode sheet 28 is provided on the lifting seat 221 for detecting the heating condition of the solid-state battery under different resistance support states.

[0041] On the basis of the above, if Figure 3 As shown, a lower base 27 is fixed on the second rack 26, and the negative electrode sheet 24 is slidably matched with the lower base 27 through a vertically distributed slide bar 241, and a buffer spring 242 is sleeved on the slide bar 241 to elastically press the negative electrode sheet 24 upward. The buffer spring 242 is used to elastically abut the negative electrode sheet 24 and the soft metal sheet 111, thereby ensuring contact stability and reducing impact loss on the soft metal sheet 111.

[0042] On the basis of the above, if Figure 3 As shown, the temperature detection mechanism 30 includes a temperature measurement module 31 distributed beside the detection area. The temperature measurement module 31 can be horizontally adjusted along a direction perpendicular to the conveying direction of the solid-state battery to adapt to the stable detection of solid-state batteries of different sizes.

[0043] In addition, in order to further improve the accuracy of temperature detection, the temperature detection mechanism 30 includes a slide 34 that can slide horizontally perpendicular to the conveying direction of the solid-state battery. Specifically, the slide 34 can slide with the supporting body of the belt conveyor mechanism 10, or can slide on a guide rail fixed to the ground. The temperature measuring module 31 is installed on the slide 34, and a wedge block 35 that is wedge-matched with the slide 34 is fixed on the second rack 26. The slide 34 is wedge-matched with the wedge block 35, and when the second rack 26 moves upward or downward, the slide 34 is driven to approach the detection area or away from the detection area respectively. By establishing power transmission between the temperature measuring module 31 and the linear reciprocating mechanism, when the linear reciprocating mechanism performs a clamping action or an unlocking action, the temperature measuring module 31 is respectively moved close to the solid-state battery and away from the solid-state battery, and the stable cooperation between the temperature detection mechanism 30 and the power supply mechanism 20 can be achieved without an additional power source, thereby ensuring the accuracy of stable detection of the temperature measuring module 31 during the detection process. In actual implementation, the oblique wedge cooperation between the slide 34 and the wedge block 35 can adopt the connection method of the dovetail groove and the dovetail slider in the existing technology, or it can adopt the connection method of the smooth wedge surface cooperation. Of course, under the smooth wedge surface cooperation, a reset spring is also required to drive the slide 34 to reset.

[0044] Further, such as Figure 3 As shown, the temperature measuring module 31 is connected to the slide 34 through a telescopic rod 32. The telescopic rod 32 is arranged along the sliding direction of the slide 34, and an extrusion spring 33 is sleeved on the telescopic rod 32. When the size of the solid-state battery is too large, the telescopic rod 32 and the extrusion spring 33 can be contracted so as not to hinder the sliding movement of the slider 34, thereby improving the adaptability to the size range of the solid-state battery.

[0045] Of course, it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
