Optionally, the testing apparatus 100 may further include a pallet 40, the pallet 40 being located on a side of the first clamping mechanism 10 away from the second clamping mechanism 20, the pallet 40 being used for carrying the test workpiece.

In some embodiments, referring to fig. 1, 2 and 3, the first clamping mechanism 10 can further include a first stationary shaft 11, a second stationary shaft 12, a first rotating jaw 13, and a second rotating jaw 14. The second stationary shaft 12 is disposed adjacent to the first stationary shaft 11. The first rotating jaw 13 is disposed on the first fixed shaft 11, and the second rotating jaw 14 is disposed on the second fixed shaft 12, it being understood that the first rotating jaw 13 and the second rotating jaw 14 can be fixed on a table top (not shown) by the first fixed shaft 11 and the second fixed shaft 12. Wherein the first rotating jaw 13 is provided with a first engagement portion 134. The second rotating jaw 14 is provided with a second engagement portion 144. Second engagement portion 144 engages with first engagement portion 134 to open or close first rotating jaw 13 and second rotating jaw 14. It is understood that the first and

second engagement portions

134, 144 may be identical in shape, the first engagement portion 134 may be a projection or a gear, etc., and the second engagement portion 144 may also be a projection or a gear, etc. So long as the first engagement portion 134 and the second engagement portion 144 can be matingly engaged together.

Alternatively, with continued reference to fig. 1, 2, and 3, the first rotating jaw 13 may include a first rotating plate 131, a first strut 132, and a first jaw 133. The first support 132 fixedly connects the first rotation plate 131 and the first jaw 133. The second rotating jaw 14 may include a second rotating plate 141, a second pillar 142, and a second jaw 143. The second support 142 fixedly connects the second rotating plate 141 and the second clamping jaw 143. A side of the first rotating plate 131 adjacent to the second rotating plate 141 is protruded in a direction of the second rotating plate 141 to form the first engaging portion 134. A side of the second rotating plate 141 adjacent to the first rotating plate 131 is protruded in a direction of the first rotating plate 131 to form a second engaging portion 144. As shown in fig. 3, the first engaging portion 134 may be located above the second engaging portion 144. The first and

second posts

132, 142 and the first and

second jaws

133, 143 are identical in structure and may be symmetrically disposed.

The ends of the first jaw 133 and the second jaw 143 are provided with arc-shaped notches so as to clamp the outer circumferential surface of a test workpiece, which may be a cylindrical battery or a square battery or the like. The outer sides of the first jaw 133 and the second jaw 143 are respectively provided with a first pole hole 101. It will be appreciated that the first pole aperture 101 may be located on a side of the first jaw 133 and the second jaw 143 facing away from the arcuate notch. Through the mode, an external power line can be connected to the outer side of the first clamping mechanism 10, and the probability of connection winding can be effectively reduced.

In some embodiments, referring to fig. 1, 2 and 3, the first clamping mechanism 10 may further include a first insulating pad 15 and a second insulating pad 16, the first insulating pad 15 being located between the first clamping jaw 133 and the first rotating plate 131, and the second insulating pad 16 being located between the second clamping jaw 143 and the second rotating plate 141. It can be understood that, since the first clamping jaw 133 and the second clamping jaw 143 are directly connected to an external power source, when a test is performed, the first clamping jaw 133 and the second clamping jaw 143 have the power source, the first rotating plate 131 and the second rotating plate 141 can have no power source through the first insulating pad 15 and the second insulating pad 16, and thus, the influence of the test power source on other devices can be effectively avoided.

Alternatively, the first insulating block 15 may have the same structure as the second insulating block 16, the first rotating plate 131 and the second rotating plate 141 may have a Z-shape or the like, the first insulating block 15 and the second insulating block 16 may have an L-shape or the like, the first clamping jaw 133 may be disposed on the L-shaped first insulating block 15, and the second clamping jaw 143 may be disposed on the L-shaped second insulating block 16, so that the overall structure may be more compact.

In some embodiments, referring to fig. 1, 2, and 3, the testing device 100 may further include a first drive mechanism 30. The first drive mechanism 30 is connected to the first rotating jaw 13. The first driving mechanism 30 may include a first driving member (not shown), a driven shaft 31, and a rotating arm 32. The first drive member may be a cam or a cylinder or the like. The first driver is connected to the driven shaft 31, and the pivot arm 32 connects the driven shaft 31 and the first pivot plate 131. The first driving member is used for driving the driven shaft 31 to rotate the first rotating plate 131 connected with the rotating arm 32, so that the first engaging portion 134 drives the second engaging portion 144, and the first rotating clamping jaw 13 and the second rotating clamping jaw 14 are opened or closed.

It can be understood that the first driving member drives the first rotating plate 131 to rotate relative to the first fixed shaft 11 through the driven shaft 31 and the rotating arm 32, and further drives the second engaging portion 144 through the first engaging portion 134, so as to drive the second clamping jaw 143 connected to the second rotating plate 141 to rotate, the first rotating clamping jaw 13 and the second rotating clamping jaw 14 are separated from each other to realize opening, and the first rotating clamping jaw 13 and the second rotating clamping jaw 14 are close to each other to realize closing. In this way, the opening and closing of the first rotating jaw 13 and the second rotating jaw 14 can be realized only by using one driving mechanism, so that the overall mechanism of the first clamping mechanism 10 can be reduced, and the energy consumption can be saved.

In some embodiments, with continued reference to fig. 3, the first clamping mechanism 10 may further include a first resilient member 17, and the first resilient member 17 may be a spring or the like. The two ends of the first elastic element 17 are respectively connected with the first support 132 and the second support 142; or the first elastic member 17 is connected at both ends thereof to the first jaw 133 and the second jaw 143, respectively. The first elastic member 17 is used to tighten the first and second clamping

jaws

133 and 143 so that the first and second clamping

jaws

133 and 143 clamp the outer peripheral surface of the test workpiece. It can be understood that the first driving mechanism 30 needs to overcome the restoring elastic force of the first elastic member 17 when driving the first clamping jaw 133 and the second clamping jaw 143 to open, and when the first clamping jaw 133 and the second clamping jaw 143 clamp the outer circumferential surface of the test workpiece, and then the driving force of the first driving mechanism 30 is cancelled, the first clamping jaw 133 and the second clamping jaw 143 clamp the test workpiece under the contraction force of the first elastic member 17.

In this way, the test workpiece can be clamped without the first drive mechanism 30 generating a driving force, so that the use of energy consumption can be further reduced.

In some embodiments, referring to fig. 1, 2 and 4, the second clamping mechanism 20 may include a fixed base 21, a drive shaft 22, a jaw member 23, a first clamping block 24, and a second clamping block 25. The jaw member 23 is provided on the holder 21. The first clamping block 24, the second clamping block 25 and the clamping jaw piece 23 are connected, second pole holes 201 are respectively formed in the outer sides of the first clamping block 24 and the second clamping block 25, the driving shaft 22 is connected with the clamping jaw piece 23, and the driving shaft 22 is used for driving the clamping jaw piece 23 to drive the first clamping block 24 and the second clamping block 25 to open or close. It will be appreciated that the first and

second blocks

24, 25 are open, i.e., away from each other, and the first and

second blocks

24, 25 are closed when they are close to each other. When the first clamping block 24 and the second clamping block 25 are closed, an inclined clamping opening may be formed between the first clamping block 24 and the second clamping block 25 to clamp one end of the test workpiece, such as a tab of a battery.

In some embodiments, with continued reference to fig. 1, 2, and 4, jaw member 23 may include a housing 231, a shaft 232, a movable block 233, and a drive jaw 234. The rotation shaft 232 and the movable block 233 are disposed in the housing 231. The movable block 233 is rotatably connected to the rotation shaft 232. The movable block 233 is provided with two driving portions 235. The drive shaft 22 is slidably disposed within the housing 231 and partially exposed relative to the housing 231, with one drive portion 235 coupled to the drive shaft 22 and the other drive portion 235 coupled to the drive pawl 234. The two rotating shafts 232, the two movable blocks 233 and the two driving claws 234 are respectively and symmetrically arranged on two sides of the driving shaft 22, the driving claws 234 are respectively connected with the first clamping block 24 and the second clamping block 25, and the driving shaft 22 is used for axially moving in the housing 231 to drive the first clamping block 24 and the second clamping block 25 to open or close.

It is understood that one end of the driving shaft 22 may be connected to a cam follower or the like, and the end of the driving shaft 22 located at the other end in the housing 231 and the side of the driving pawl 234 facing the inside of the housing 231 may be correspondingly provided with an opening in which the driving portion 235 is received. When the driving shaft 22 moves downwards, the rotating shaft 232 can be driven to rotate, and then the two driving claws 234 are driven to move away from each other, so that the first clamping block 24 and the second clamping block 25 connected with the driving claws 234 are opened; when the driving shaft 22 moves upward, the rotating shaft 232 is driven to rotate, and the two driving pawls 234 are driven to approach each other, so that the first clamping block 24 and the second clamping block 25 connected with the driving pawls 234 are closed.

In some embodiments, with continued reference to fig. 1, 2, and 4, second clamping mechanism 20 may further include a second resilient member 26 and two connecting blocks 27. The connection block 27 may be L-shaped or the like. The second elastic member 26 may be a spring or the like. The second elastic element 26 is sleeved on the driving shaft 22, wherein one end of one connecting block 27 is connected with the first clamping block 24, and the other end is connected with a driving claw 234; the other connecting block 27 has one end connected to the second clamping block 25 and the other end connected to the second driving pawl 234. It will be appreciated that movement of the drive shaft 22 moves the connecting block 27 and thus the first and second clamping blocks 24 and 25 via the drive pawl 234. The structure of the second clamping mechanism 20 can be more firm and stable in the above manner.

In some embodiments, the second clamping mechanism 20 may further include a third insulating spacer block (not shown) and a fourth insulating spacer block (not shown). A third insulating spacer block is located between the first clamping block 24 and the connecting block 27 and a fourth insulating spacer block is located between the second clamping block 25 and the connecting block 27.

It can be understood that, because the first clamping block 24 and the second clamping block 25 are directly connected to an external power supply, when a test is performed, the first clamping block 24 and the second clamping block 25 have current, and the jaw members 23 and the like can be isolated from the current through the third insulating cushion block and the fourth insulating cushion block, so that the influence of the tested power supply on other equipment can be effectively avoided.

It should be understood that the above structures do not represent all of the components of the testing device 100, and that the testing device 100 may be provided with other components for performing its functions, such as electrical slip rings, etc.
