[0038] It should be noted that Figure 2The test unit 20 composed of two high-speed battery electrical performance detection devices is shown in the figure. The battery can be directly transferred between the two test turrets of the two high-speed battery electrical performance detection devices, for example, the transfer is realized at the near point (tangent point) of the two test turrets. Of course, a transfer star wheel 23 can also be set between the two test turrets to realize the transfer of the battery between the test turrets, that is, the battery on one of the test turrets is first transferred to the transfer star wheel 23, and then transferred from the transfer star wheel 23 to the other test turret. The battery is directly transferred between the two test turrets or the transfer star wheel 23 is set between the two test turrets to realize the transfer of the battery between the test turrets. The implementation structure and method are all known to those skilled in the art, which is not the inventive concept of the present utility model, so no specific explanation and description are made. In addition, the structures of the multiple test turrets contained in the test unit 20 are all the same, and the multiple test instruments contained in the test unit 20 can be the same or different, preferably different test instruments, so as to realize the collection / testing of different electrical performance parameters of the battery.

The rejection mechanism 50 is used to reject batteries that fail the test from the second conveyor line 30. The structure of the rejection mechanism 50 can be known to those skilled in the art and will not be repeated here.

[0042] Specifically, the test turret structures included in the test unit 20 are basically the same. The structure and working method of one of them are described below as an example. Please refer to Figure 5 and Figure 6 The test turret includes a transmission shaft 2160, a turret body, a cam 2150 and a plurality of detection probe assemblies 2140. The turret body is used to install the detection probe assemblies 2140 and limit / carry batteries. The turret body is fixedly connected to the transmission shaft 2160. The turret body and the transmission shaft 2160 can rotate around a selected axis. The cam 2150 rotates in coordination with the turret body or the transmission shaft 2160, that is, when the turret body and the transmission shaft 2160 rotate, the cam 2150 remains fixed. A plurality of detection probe assemblies 2140 are arranged on the turret body and are used to electrically connect to batteries located on the turret body. In addition, the detection probe assemblies 2140 also cooperate with the cam 2150 and can move along a first direction to achieve electrical connection or disconnection with the batteries. The aforementioned test instrument is electrically connected to the detection probe assembly 2140.

[0043] Specifically, the turret body includes a first rotating body and a second rotating body which are arranged in sequence along a first direction, and a plurality of product limiting structures are arranged on the first rotating body, and the plurality of product limiting structures are arranged in sequence along the circumference of the first rotating body, and the product limiting structure is used to limit the battery on the first rotating body; a plurality of detection probe assemblies 2140 are arranged on the second rotating body, and each detection probe assembly 2140 corresponds to at least one product limiting structure, and the detection probe assembly 2140 is movably cooperated with the second rotating body in the first direction, and when the detection probe assembly 2140 rotates with the turret body, the outward region and the return region of the cam 2150 are cooperated with the detection probe assembly 2140 in sequence, and the detection probe assembly 2140 moves along the first direction, so that the detection probe assembly 2140 is electrically contacted or separated from the battery, and the product limiting structure and the detection probe assembly 2140 rotate together, and the battery to be tested can remain relatively still with the probe before detection, thereby ensuring the detection accuracy.

[0044] Specifically, when the detection probe assembly 2140 cooperates with the outward region of the cam 2150, the detection probe assembly 2140 moves from the first station toward the second station along the first direction, and when the detection probe assembly 2140 cooperates with the return region of the cam 2150, the detection probe assembly 2140 moves from the second station toward the first station along the first direction, and when the detection probe assembly 2140 is located at the second station, the detection probe assembly 2140 can be electrically connected to the battery located on the product limiting structure, and the first direction is parallel to the axial direction of the turret body.

[0045] It can be understood that the first rotating body and the second rotating body are fixedly connected, and the two rotate synchronously. The cam 2150 is arranged on the side of the second rotating body away from the first rotating body. Exemplarily, the first rotating body and the second rotating body are fixedly connected to the transmission shaft 2160, and the cam 2150 is connected to the transmission shaft 2160 via a bearing, so that when the turret body rotates, the cam 2150 remains fixed. Of course, the cam 2150 can also be set separately from the turret body, that is, the cam 2150 is fixed on a support frame separated from the turret.

[0046] Specifically, a transmission gear and a torque protector are also fixed on the transmission shaft 2160. The transmission gear is connected to a driving mechanism such as a motor through a chain or a belt, and rotates when driven by the driving mechanism.

[0047] Specifically, the first rotating body includes a product carrier plate 2110 and a feed transfer star wheel 2120. The feed transfer star wheel 2120 is fixedly arranged above the product carrier plate 2110 along the first direction. The outer peripheral edge of the feed transfer star wheel 2120 is provided with a plurality of groove-like structures. The product carrier plate 2110 and the groove-like structures are enclosed to form a restriction structure. The restriction structure is mainly used to restrict the movement of the battery so that the battery rotates on the turret body together with the turret body. It can be understood that the groove-like structure is a notch arranged on the outer peripheral edge of the feed transfer star wheel 2120. The notch should be sufficient to allow the battery to rotate on the turret body together with the turret body. The specific parameters of the groove-like structure are not limited here.

[0048] Specifically, a limit protection block 2130 is also provided on the feed transfer star wheel 2120. The limit protection block 2130, the groove structure and the product carrier plate 2110 are enclosed together to form a limit structure. The limit protection block can be provided on one side of the groove structure. The limit protection block 2130 can contact the battery located in the limit structure, and the side of the limit protection block 2130 facing the limit structure is an arc structure matching the outer shape structure of the battery. It can be understood that the limit protection block 2130 is mainly used to limit the relative movement of the battery on the turret body and the detachment from the turret body. It should be noted that the battery is restricted in movement by the restriction structure on the turret body, rather than being directly fixed.

[0049] Specifically, a guide mechanism extending along the first direction is fixedly provided on the second rotating body, and the detection probe assembly 2140 is movably connected to the guide mechanism and can move along the guide mechanism. More specifically, the detection probe assembly 2140 and the guide mechanism are movably cooperated by sliding or rolling. Exemplarily, the guide structure can be a guide rail, etc.

[0050] Specifically, the detection probe assembly 2140 includes a probe 2141, a probe frame and a cam follower 2145. The probe 2141 is set on the probe frame, the cam follower 2145 is fixedly connected to the probe frame, the probe frame and the second rotating body are movably cooperated along the first direction, the cam follower 2145 and the cam 2150 are movably cooperated, and the cam follower 2145 rotates synchronously with the turret body, so that the cam follower 2145 contacts different areas of the cam 2150, thereby generating pressure / thrust between the cam follower 2145 and the cam 2150 to drive the detection probe assembly 2140 to move along the first direction.

[0051] Specifically, the probe rack includes a probe fixing component 2142, a first supporting component 2143 and a second supporting component 2144. The probe fixing component 2142 is fixedly connected to the first supporting component 2143. The probe 2141 is arranged on the probe fixing component 2142. The probe fixing component 2142 is fixedly arranged on the first supporting component 2143. The second supporting component 2144 is fixedly connected to the cam follower 2145. The second supporting component 2144 is movably connected to the second rotating body. The first supporting component 2143 and the second supporting component 2144 are adjustably connected. The relative position of the first supporting component 2143 and the second supporting component 2144 can be adjusted along the first direction to adapt to batteries of different sizes and models. That is, by adjusting the first supporting component 2143, the initial height of the probe can be changed to connect with batteries of different sizes and models.

[0052] Specifically, the first support member 2143 is connected to the second support member 2144 via a connecting member, wherein the first support member 2143 is provided with a strip hole extending along the first direction, a part of the connecting member passes through the strip hole and is threadedly connected to the second support member 2144, and the first support member 2143 is clamped and fixed between the connecting member and the second support member 2144 by screwing the connecting member, or the first support member 2143 can move relative to the second support member 2144 along the first direction, that is, the connecting member can be a bolt, etc.

[0053] Specifically, the cam 2150 is provided with an annular guide groove 2151, the guide groove 2151 has a forward region and a return region, the cam follower 2145 is movably disposed in the guide groove 2151 and can move along the guide groove 2151. It can be understood that the groove wall of the guide groove 2151 is a curved surface that undulates along the first direction. More specifically, by setting the curved surface of the guide groove 2151 of the cam 2150, the detection start time and end time of the detection probe assembly 2140 can be accurately controlled.

[0054] Specifically, the structures of the first test instrument 22-1 and the second test instrument 22-2 may be the same, and their functions may be the same or different. Please refer to Figure 7 The test instrument may include an electric slip ring 2205, a test instrument body 2201, a distribution box 2202, a slewing bearing 2203, a coupling 2204 and other structural parts. The coupling 2204 is connected to the transmission shaft 2160 and drives the slewing bearing 2203 to rotate, thereby driving the test instrument body 2201 and the distribution box 2202 to rotate. Of course, the test instrument 2201 can also be fixed somewhere and the electrical wiring can be transferred through the electric slip ring 2205. The specific structure and configuration of the test instrument will not be described in detail here. It only needs to ensure that it can be electrically connected to multiple batteries that are kept in motion on the test turret.
