The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0043] The embodiments provide a positioning clamp and a material conveying system. Figure 1 As shown in the drawing, the material conveying system comprises a conveying mechanism 100 and the positioning clamp provided by the embodiments, and the positioning clamp is used for clamping and positioning a battery to be tested 10. The conveying mechanism 100 comprises two conveying rails 101 which are parallel and spaced apart, and the positioning clamp is slidably arranged on the two conveying rails 101. Through the conveying rails 101, the positioning clamp and the battery to be tested 10 thereon can be conveyed between various detection stations, so as to improve the degree of automation and work efficiency.

[0044] As shown in the drawings, Figure 1 , Figure 3 and Figure 4 The positioning clamp provided by the embodiments comprises a support seat 1, a clamping mechanism 2 and a to-position detection mechanism 3.

[0045] The support seat 1 is provided with a battery placing position, which is used for placing the battery to be tested 10, so as to ensure the support stability of the battery to be tested 10 during testing. The clamping mechanism 2 comprises a plurality of positioning clamp assemblies, which are sequentially arranged along the circumference of the battery placing position. Each positioning clamp assembly can move towards or away from the battery to be tested 10 on the battery placing position, so as to be clamped to the circumferential side of the battery to be tested 10. That is, the plurality of positioning clamp assemblies can realize clamping of the battery to be tested 10 through opening and closing actions, and can be applied to various sizes of the battery to be tested 10, so as to have high flexibility and effectively improve the work efficiency.

[0046] In the embodiment, the support base 1 is provided with two battery placing positions, and the two battery placing positions are separated by a partition. The two batteries to be tested 10 are respectively placed on the battery placing positions on the two sides of the partition. When the plurality of positioning and clamping assemblies are close to the batteries to be tested 10, the positioning and clamping assemblies can press and abut the batteries to be tested 10 against the partition. The partition can position and abut one side of the battery to be tested 10, and the positioning and clamping assemblies can clamp and position the other three sides of the battery to be tested 10, so as to realize reliable positioning of the battery to be tested 10. Of course, in other embodiments, only one battery placing position can be provided, and the four sides of the battery to be tested 10 can be clamped and positioned by the plurality of positioning and clamping assemblies; or, four battery placing positions can be provided, and the four battery placing positions are separated by a partition in the shape of a cross. The positioning and clamping assemblies can also press and abut the battery to be tested 10 against the partition. The specific arrangement of the battery placing position can be determined according to the requirement, which is not limited here.

[0047] As shown in Figures 1-3 , the plurality of positioning and clamping assemblies include a first clamping assembly 21 and a second clamping assembly 22. The first clamping assembly 21 includes a first positioning and clamping 211 and two second positioning and clamps 212. The two second positioning and clamps 212 are parallel and adjustably arranged along a first direction on the two sides of the battery placing position. The first positioning and clamping 211 is arranged on one side of the two second positioning and clamps 212 in a second direction perpendicular to the first direction. In the embodiment, the first direction is parallel to the width direction of the battery to be tested 10, and the second direction is parallel to the length direction of the battery to be tested 10. The two second positioning and clamps 212 are close to or away from each other along the first direction, which can drive the first positioning and clamping 211 to move close to or away from the battery placing position along the second direction. That is, the two second positioning and clamps 212 are linked with the first positioning and clamping 211, so as to realize clamping and fixing of the three sides of the battery to be tested 10.

[0048] Specifically, referring to Figures 2-5 , the first clamping assembly 21 further includes a first push block 213 and two first push plates 214. The two first push plates 214 are slidably arranged on the support base 1 along the first direction and are respectively fixedly connected with the two second positioning and clamps 212. The first push block 213 is movably arranged between the two first push plates 214 along the second direction. When the first push block 213 moves to the middle of the two first push plates 214 along the second direction, the first push block 213 can push the two first push plates 214 to move away from each other along the first direction, so as to drive the two second positioning and clamps 212 to move away from each other.

[0049] As shown in Figure 2 , Figure 3 and Figure 5As shown, two first push plates 214 are respectively provided with first inclined surfaces 2141 on the side facing each other, and the included angle between the two first inclined surfaces 2141 is open towards the first push block 213. When the first push block 213 moves to the middle of the two first push plates 214 along the second direction, the two top corners of the first push block 213 respectively slide against the two first inclined surfaces 2141, thereby pushing the two first push plates 214 to move along the first direction to the two sides of the first push block 213 respectively.

[0050] In the embodiment, two first push wheels 2131 are respectively arranged at the two top corners of the first push block 213. The rotation shafts of the first push wheels 2131 are parallel to the height direction, and the wheel bodies of the first push wheels 2131 protrude from the first push block 213. When the first push block 213 moves to the middle of the two first push plates 214 along the second direction, the first push wheels 2131 at the two ends of the first push block 213 can respectively roll with the two first inclined surfaces 2141. The rolling of the first push wheels 2131 on the first inclined surfaces 2141 helps to improve the smoothness when the first push block 213 pushes the first push plates 214 to move.

[0051] Of course, in other embodiments, the first push wheels 2131 can not be arranged, and the two top corners of the first push block 213 can be respectively arranged as rounded corners. In this way, the two first push plates 214 can also be pushed to move along the first direction to the two sides of the first push block 213 by the cooperation of the first push block 213 and the first inclined surfaces 2141.

[0052] Further, as shown in Figure 1 , Figure 3 and Figure 4 , the first clamping assembly 21 further comprises a first driving member 219 for driving the first push block 213 to move. In the embodiment, the side of the support seat 1 is provided with a first support platform, the fixed end of the first driving member 219 is mounted on the first support platform, and the output end of the first driving member 219 is connected with the first push block 213 to drive the first push block 213 to move along the second direction. Exemplarily, the first driving member 219 can be a cylinder, an oil cylinder or a motor in the prior art.

[0053] Further, a first guide structure is arranged between the first push block 213 and the first support platform to ensure the stability of the movement of the first push block 213. The first guide structure comprises a first sliding rail 13 extending along the second direction and a first sliding block in sliding cooperation with the first sliding rail 13, one of the first sliding rail 13 and the first sliding block is arranged on the first push block 213, and the other is arranged on the first support platform.

[0054] More specifically, referring to Figure 2 and Figure 3The first clamping assembly 21 further comprises a first elastic reset member 215 capable of driving the first push plate 214 to return to the original position, thereby driving the second positioning clamp 212 to return to the original position. In the embodiment, the support seat 1 is provided with a support plate 11, and two first push plates 214 are respectively and slidably arranged on the support plate 11. The support plate 11 is provided with two baffles 12, and the two baffles 12 are respectively located on the sides away from each other of the two first push plates 214. One first elastic reset member 215 is arranged between each first push plate 214 and the baffle 12. When the first push block 213 moves to the middle of the two first push plates 214, the two first push plates 214 respectively move to both sides and press the corresponding first elastic reset members 215. When the first push block 213 moves away from the two first push plates 214 in the second direction, the two first push plates 214 respectively return to the original position under the driving of the two first elastic reset members 215. The first elastic reset member 215 can be a spring in the prior art.

[0055] Preferably, a second guide structure is arranged between the first push plate 214 and the support plate 11 to guide the sliding of the first push plate 214 on the support plate 11. The second guide structure comprises a second sliding rail 14 extending in the first direction and a second sliding block in sliding cooperation with the second sliding rail 14. The second sliding rail 14 and the second sliding block are provided with two groups to correspond to the two first push plates 214 respectively. One of the second sliding rail 14 and the second sliding block is arranged on the first push plate 214, and the other is arranged on the support plate 11.

[0056] Continuing to refer to Figure 2 , Figure 4 and Figure 5 The first clamping assembly 21 further comprises two second push blocks 216 and two second push plates 217. The two second push blocks 216 are respectively arranged on the two first push plates 214, and the second push plate 217 is fixedly connected with the first positioning clamp 211. The two second push plates 217 are respectively in sliding cooperation with the two second push blocks 216, and the second push plate 217 is located on the side of the second push block 216 away from the first positioning clamp 211. When the two first push plates 214 respectively move away from each other in the first direction, the first push plate 214 drives the second push block 216 to push the second push plate 217 to move away from the battery placement position in the second direction, thereby driving the first positioning clamp 211 to move away from the battery placement position in the second direction. That is, through the cooperation of the first push block 213, the first push plate 214, the second push block 216 and the second push plate 217, the linkage between the first positioning clamp 211 and the two second positioning clamps 212 can be realized. When the two second positioning clamps 212 respectively move away from the battery placement position, the first positioning clamp 211 also moves away from the battery placement position, thereby realizing the opening of the first clamping assembly 21.

[0057] Specifically, the second pushing block 216 is provided with a pushing portion protruding from the side of the second pushing block 216 away from the first positioning clamp 211. The second pushing plate 217 is provided with a second inclined surface 2171, and the included angle between the two second inclined surfaces 2171 on the two second pushing plates 217 is open towards the first positioning clamp 211. When the two first pushing plates 214 drive the two second pushing blocks 216 to move away from each other, the pushing portion on the second pushing block 216 slides with the second inclined surface 2171 on the second pushing plate 217, and pushes the second pushing plate 217 to move away from the battery placement position in the second direction.

[0058] In the embodiment, the pushing portion of the second pushing block 216 is provided with a second pushing wheel 2161. The rotating shaft of the second pushing wheel 2161 is parallel to the height direction, and the wheel body of the second pushing wheel 2161 protrudes from the pushing portion. When the two second pushing blocks 216 move away from each other in the first direction, the two second pushing wheels 2161 can respectively roll with the second inclined surface 2171 on the second pushing plate 217 on the two sides. The second pushing wheel 2161 rolls on the second inclined surface 2171, which helps to improve the smoothness when the second pushing block 216 pushes the second pushing plate 217 to move. Of course, in other embodiments, the second pushing wheel 2161 can also not be provided on the pushing portion, and the pushing operation on the second pushing plate 217 can be directly realized by the cooperation of the pushing portion and the second inclined surface 2171.

[0059] For specific reference Figure 2 and Figure 5 The first clamping assembly 21 further comprises a second elastic reset member 218 for driving the first positioning clamp 211 to return to the original position. In the embodiment, the first pushing plate 214, the second pushing plate 217 and the second pushing block 216 are located on the side of the support plate 11 away from the battery placement position, and the first positioning clamp 211 is located on the side of the support plate 11 towards the battery placement position. The first clamping assembly 21 further comprises a connecting rod, a through hole is formed in the support plate 11, and the connecting rod is movably arranged through the through hole. The two ends of the connecting rod are respectively connected to the second pushing plate 217 and the first positioning clamp 211. The second elastic reset member 218 is sleeved outside the connecting rod, and the two ends of the second elastic reset member 218 abut against the first positioning clamp 211 and the support plate 11 respectively. When the two second pushing blocks 216 move away from each other in the first direction, the second pushing plate 217 drives the first positioning clamp 211 to move away from the battery placement position in the second direction, and presses the corresponding second elastic reset member 218. When the two second pushing blocks 216 return to the original position, the second elastic reset member 218 drives the first positioning clamp 211 to move towards the battery placement position in the second direction, and drives the second pushing plate 217 to return to the original position. Exemplarily, the second elastic reset member 218 can be a spring in the prior art.

[0060] Optionally, continuing to refer to Figure 1 and Figure 4The second clamping assembly 22 comprises a third positioning clamp 221 arranged on the other side of the two second positioning clamps 212 in the second direction. The third positioning clamp 221 is movable relative to the support base 1 in the second direction. The third positioning clamp 221, the first positioning clamp 211 and the two second positioning clamps 212 can clamp the four sides of the battery 10 to be tested. When the third positioning clamp 221, the first positioning clamp 211 and the two second positioning clamps 212 are all away from the battery placement position, the clamping mechanism 2 is opened to facilitate the placement of the battery 10 to be tested. When the third positioning clamp 221, the first positioning clamp 211 and the two second positioning clamps 212 are all close to the battery placement position, the clamping mechanism 2 is closed to clamp and fix the battery 10 to be tested on the battery placement position.

[0061] Specifically, the second clamping assembly 22 further comprises a second driving member 222 for driving the third positioning clamp 221 to move. In the embodiment, the other side of the support base 1 is provided with a second support platform. The fixed end of the second driving member 222 is mounted on the second support platform, and the output end of the second driving member 222 is connected with the third positioning clamp 221 to drive the third positioning clamp 221 to move in the second direction. Exemplarily, the second driving member 222 can be a cylinder, an oil cylinder or a motor in the prior art.

[0062] Further, a third guide structure is arranged between the third positioning clamp 221 and the second support platform to ensure the stability of the third positioning clamp 221 when moving. The third guide structure comprises a third sliding rail 15 extending in the second direction and a third sliding block in sliding cooperation with the third sliding rail 15. One of the third sliding rail 15 and the third sliding block is arranged on the third positioning clamp 221, and the other is arranged on the second support platform.

[0063] Continuing to refer to Figure 1 The in-place detection mechanism 3 is arranged on the support base 1, and specifically arranged on the first support platform and the second support platform on both sides of the support base 1. The in-place detection mechanism 3 can output detection light to the battery 10 to be tested, and the detection light is parallel to the top surface of the battery 10 to be tested. Through the in-place detection mechanism 3, whether the battery 10 to be tested is placed flat on the support base 1 can be detected, which helps to improve the positioning accuracy.

[0064] Specifically, the in-place detection mechanism 3 comprises a first detection assembly 31 and a second detection assembly 32. The first detection assembly 31 and the second detection assembly 32 are arranged on the support base 1 in a height direction and emit detection light rays with different heights, respectively. The first detection assembly 31 outputs first detection light rays to the battery 10 to be measured, and the first detection light rays are flush with the top surface of the battery 10 to be measured; the second detection assembly 32 outputs second detection light rays to the battery 10 to be measured, and the second detection light rays are slightly higher than the highest point of the top of the battery 10 to be measured. The first detection assembly 31 and the second detection assembly 32 can be optoelectronic switches in the prior art, and their structures and principles will not be described here.

[0065] The operation principle of the material conveying system provided in the embodiment is as follows:

[0066] Firstly, an empty positioning clamp is placed on the feeding position of the conveying mechanism 100, and the battery 10 to be measured is placed in the positioning clamp by the feeding mechanical arm.

[0067] Specifically, when the battery 10 to be measured is lowered, the second detection assembly 32 will first sense the battery 10 to be measured. At this time, the first driving member 219 is started to push the first push block 213 to move along the first sliding rail 13 to the battery placing position. The two first push wheels 2131 on the first push block 213 respectively push the two first push plates 214 on the two sides away from each other, and press the corresponding two first elastic return members 215. The two first push plates 214 can also respectively drive the two second positioning clamps 212 to move apart along the first direction. When the two first push plates 214 move away from each other, the two second push blocks 216 on the two first push plates 214 also move away from each other. The two second push wheels 2161 are respectively in rolling engagement with the second inclined surfaces 2171 on the second push plates 217 on the two sides, and push the second push plates 217 away from the battery placing position. The second push plates 217 drive the first positioning clamp 211 to move and press the second elastic return member 218. At the same time, the second driving member 222 is started to drive the third positioning clamp 221 to move away from the battery placing position along the third sliding rail 15. Finally, the battery 10 to be measured is stably placed on the battery placing position.

[0068] Secondly, the battery 10 to be measured is clamped by the positioning clamp.

[0069] Specifically, in this step, after the battery 10 to be tested is completely placed in the positioning fixture, when the first detection assembly 31 can sense the battery 10 to be tested and the second detection assembly 32 cannot sense the battery 10 to be tested, it is proved that the battery 10 to be tested has been placed flat in position. At this time, the first driving member 219 is started, the first push block 213 is retreated along the first slide rail 13, and the two second positioning clamps 212 are driven to approach each other to clamp two large faces of the battery 10 to be tested by the elastic force of the first elastic reset member 215 and the second elastic reset member 218, and the first positioning clamp 211 returns to the original position and clamps one side face of the battery 10 to be tested. At the same time, the second driving member 222 is started, the third positioning clamp 221 is driven to approach the battery 10 to be tested along the third slide rail 15, and clamps the other side face of the battery 10 to be tested.

[0070] The third step is material conveying.

[0071] Specifically, after the four faces of the battery 10 to be tested are positioned and clamped, the positioning fixture and the battery 10 to be tested thereon are conveyed to the next work station through the conveying guide rail 101. The principle of unclamping and discharging is the same, and the conveying mechanism 100 further conveys another empty positioning fixture to the feeding position.

[0072] The fourth step is to restore the initial state after the actions of the mechanisms are completed.
