The embodiment of the application provides a clamp. Referring to fig. 1 to 3, a fixture 100 according to an embodiment of the present disclosure includes a mounting platform 110, a positioning plate 120, a first positioning mechanism 130, a second positioning mechanism 140, and a third positioning mechanism 150. The positioning plate 120 is disposed on the mounting platform 110. The mounting platform 110 is provided with a first station and a second station, which are respectively located at two sides of the positioning plate 120 along the first direction. For convenience of description, the first direction, the second direction and the third direction are defined in the embodiments of the present application, and the first direction, the second direction and the third direction are perpendicular to each other. As shown in fig. 1, the first direction, the second direction and the third direction may correspond to an X direction, a Y direction and a Z direction of the spatial coordinate system, respectively. It is also understood that the first direction, the second direction, and the third direction correspond to a front-back direction, a left-right direction, and an up-down direction of the jig 100, respectively.

In the embodiment of the present application, the fixture 100 is used for clamping a first workpiece and a second workpiece, the second workpiece includes two symmetrical workpiece units, and a connecting piece is connected between the two workpiece units, so that the two workpiece units and the connecting piece form a second workpiece together. The two workpiece units are respectively placed on the first station and the second station, and the positioning plate 120 is used for positioning the first workpiece. For example, the fixture 100 of the embodiment of the application can be used for positioning the battery core 101 and the battery top cover 103 of the new energy battery. The top cover 103 is a first workpiece, and the battery cell 101 is a second workpiece. Referring to fig. 7, the battery cell 101 includes two battery cells 101, and an interposer 102 is connected between the two battery cells 101. Referring to fig. 8, a terminal 1031 is provided on the top cover 103. During welding, the terminal 1031 of the adapter plate 102 and the top cover 103 are welded together. With reference to fig. 1 and 9, before the interposer 102 and the top cover 103 are welded, the top cover 103 is first placed on the positioning plate 120 of the fixture 100, and then the two battery cells 101 are respectively placed on two stations on two sides of the positioning plate 120, where each battery cell 101 is located on one station. After the battery is placed, the interposer 102 covers the top cover 103, and the two battery cells 101 are respectively located on two sides of the top cover 103.

Referring to fig. 3, the positioning plate 120 is provided with a positioning post 121 and a positioning hole 122 for positioning the first workpiece. The first workpiece (the top cover 103) is positioned by the positioning posts 121 and the positioning holes 122. The positioning posts 121 are disposed on two sides of the positioning hole 122 along the first direction. During positioning, both sides of the first workpiece abut against the positioning posts 121, and the positioning holes 122 are used for profiling positioning. Taking the first workpiece as the battery top cover 103 as an example, during positioning, the pole 1031 on the top cover 103 is located in the positioning hole 122, and the positioning posts 121 abut against two sides of the top cover 103 along the first direction, so as to position the top cover 103 in the first direction. The fitting of pole 1031 with positioning hole 122 is profiling positioning, and the shape and size of positioning hole 122 are adapted to the shape and size of pole 1031 of top cover 103, so that pole 1031 can be profiling positioning through positioning hole 122. In addition, as shown in fig. 3, positioning blocks 123 may be further provided at both ends of the positioning plate 120 in the second direction. The top end of the positioning block 123 is higher than the top end of the positioning plate 120, so that the positioning block 123 forms a stop for the top cover 103, the positioning block 123 abuts against the two ends of the top cover 103 along the second direction, and the top cover 103 is positioned in the second direction.

As shown in fig. 1, a first positioning mechanism 130 is disposed at an end of the first station and the second station away from each other in the first direction. One end of the first station and the second station adjacent to each other in the first direction is provided with a second positioning mechanism 140. The two ends of the first station along the second direction and the two ends of the second station along the second direction are both provided with a third positioning mechanism 150. The first positioning mechanism 130, the second positioning mechanism 140 and the third positioning mechanism 150 around the first station are used to position the workpiece unit of the second workpiece on the first station, that is, to position the battery cell 101 on the first station. The workpiece unit of the second workpiece at the second station is positioned by the first positioning mechanism 130, the second positioning mechanism 140 and the third positioning mechanism 150 around the second station, that is, the battery cell 101 at the second station is positioned. After the two battery cells 101 are positioned, the connecting pieces connected to the two battery cells 101 are also positioned, so that the relative positions of the battery cells 101, the connecting pieces and the top cover 103 are accurately positioned, and the adapter pieces 102 and the top cover 103 are conveniently welded in the following process. It can also be said that the relative position between the first and second workpieces is accurately positioned. And the positioning structure is simple, and the positioning precision is higher.

As shown in fig. 2, there are two first positioning mechanisms 130, two first positioning mechanisms 130 are respectively located at one end of the first station and one end of the second station, and the two first positioning mechanisms 130 are disposed oppositely. As shown in fig. 4, the first positioning mechanism 130 includes a first driving member 131 and a first abutting member 132. The first driving member 131 is connected to the first abutting member 132, and the first driving member 131 can drive the first abutting member 132 to move along the first direction, so that the first abutting member 132 abuts against the workpiece unit (the battery cell 101), and the workpiece unit (the battery cell 101) is positioned. As shown in fig. 4, the first driving member 131 may adopt an air cylinder, and the air cylinder stretches and retracts to drive the first abutting member 132 to move, so as to push against the workpiece unit (the battery cell 101) or release the workpiece unit (the battery cell 101). The first abutting member 132 may be an elastic head, a baffle, etc., such as a plastic head or a rubber head.

As shown in fig. 2, one second positioning mechanism 140 is provided, and one second positioning mechanism 140 can position the workpiece units (electric cores 101) on two sides at the same time. Specifically, as shown in fig. 5, the second positioning mechanism 140 includes a second driving element 141, a third driving element 142 and a second abutting element 143. The second driving member 141 is connected to the third driving member 142, and the third driving member 142 is connected to the second abutting member 143. The second driving element 141 drives the third driving element 142 to move along the second direction (Y direction) so as to enable the second abutting piece 143 on the third driving element 142 to approach the workpiece unit. The third driver 142 drives the second contact member 143 to move in the first direction (X direction), and the second contact member 143 contacts the workpiece unit to position the workpiece unit. As shown in fig. 1, since the second positioning mechanism 140 is disposed at one end of the first station and the second station that are close to each other in the first direction (X direction), the second positioning mechanism 140 is also located between the first station and the second station in the first direction. In order to avoid the loading of the first workpiece and the second workpiece, as shown in fig. 5, the second positioning mechanism 140 is designed to include a second driving element 141, and the second driving element 141 can drive the third driving element 142 and the second abutting element 143 to move along the second direction (Y direction), so that the second abutting element 143 is far away from the workpiece during the loading, and the second abutting element 143 can be close to the workpiece to perform the positioning after the loading is completed.

In one embodiment, as shown in fig. 5, the second driving element 141 can be a large-bore clamp cylinder. The number of the third driving members 142 is two, and the two third driving members 142 are respectively arranged on two clamp heads of the large-caliber opening clamp cylinder. When the large-caliber opening clamp cylinder as the second driving element 141 is opened, the two third driving elements 142 are far away from each other and from the workpiece on the mounting platform 110; when the large-caliber opening clamp cylinder contracts, the two third driving pieces 142 approach each other and approach the workpiece on the mounting platform 110. The third driving member 142 can be a pneumatic finger, and two fingers of each pneumatic finger are provided with the second abutting parts 143. Both fingers of the pneumatic finger move in a first direction (X direction). The two second abutments 143 on each pneumatic finger are used to abut against the two workpiece units, respectively. With reference to fig. 1 and 5, when the two fingers of the pneumatic finger are opened along the first direction (X direction), the second abutting parts 143 on the two fingers abut against the workpiece units on the two sides of the positioning plate 120, respectively, so as to achieve positioning; when the two fingers are contracted in the first direction (X direction), the second abutment members 143 are separated from the workpiece units corresponding to the respective second abutment members 143. In the embodiment of the application, since the third driving member 142 employs a pneumatic finger, different workpiece units on the first station and the second station can be positioned by the same third driving member 142, so that the structure is simplified, and the cost is reduced.

In summary, the first positioning mechanism 130 and the second positioning mechanism 140 can achieve accurate positioning of the second workpiece along the first direction (X direction).

As shown in fig. 5, a first slide rail slider structure 111 may be provided to guide the movement of the third driver 142 and the second abutment 143. The slide rail of the first slide rail and slide block structure 111 is connected to the mounting platform 110, and the slide block of the first slide rail and slide block structure 111 is connected to the third driving member 142.

As shown in fig. 2, a third positioning mechanism 150 is provided for each station. Referring to fig. 6, the third positioning mechanism 150 includes a fourth driving element 151 and a third abutting element 152, the fourth driving element 151 is connected to the third abutting element 152, the fourth driving element 151 can drive the third abutting element 152 to move along the second direction (Y direction), so that the third abutting element 152 can abut against the workpiece unit, thereby positioning the workpiece unit in the second direction.

In one embodiment, as shown in fig. 6, the fourth driving element 151 may be a large-diameter split clamp cylinder. The two chucks of the large-caliber opening clamp cylinder serving as the fourth driving part 151 are respectively provided with a third abutting part 152, and the third abutting parts 152 on the two chucks are respectively arranged at two ends of a station (a first station or a second station) along the second direction. When the two clamping heads of the large-caliber opening clamping cylinder are opened, the two third butting parts 152 are far away from each other and far away from the workpiece unit on the station; when the two chucks of the large-caliber opening clamp cylinder contract, the two third abutting pieces 152 approach to each other and abut against the workpiece unit on the station, so that the workpiece unit is positioned in the second direction (Y direction).

As shown in fig. 1, a third positioning mechanism 150 is correspondingly disposed at each of the first station and the second station, so that the third positioning mechanism 150 corresponding to each station can position the workpiece unit at the station in the second direction (Y direction).

As shown in fig. 6, the third abutting member 152 may be U-shaped, such that two abutting heads are provided on one third abutting member 152, and the two abutting heads are spaced apart from each other in the second direction, such that the two abutting heads abut against different positions of the side of the workpiece unit, and the positioning effect is better.

As shown in fig. 6, at least one of the two third abutments 152 on each third positioning mechanism 150 is connected with a detection piece 153, and the detection piece 153 moves along with the third abutments 152. The mounting platform 110 is provided with a sensor 112 for sensing the detecting piece 153, so that whether the third positioning mechanism 150 is moved to the right position can be detected by the sensor 112.

In summary, the first positioning mechanism 130, the second positioning mechanism 140 and the third positioning mechanism 150 can achieve accurate positioning of the second workpiece along the first direction (X direction) and the second direction (Y direction). As shown in fig. 9, it can also be understood that the first positioning mechanism 130 and the second positioning mechanism 140 position the short sides of the battery cell 101, and the third positioning mechanism 150 positions the long sides of the battery cell 101.

The distance detecting device 124 can detect the distance between the portion of the first workpiece located in the positioning hole 122 and the distance detecting device 124. Taking the top cover 103 of the battery as an example, the pole 1031 of the top cover 103 is positioned in the positioning hole 122, and the distance between the pole 1031 and the distance detecting device 124 can be detected by the distance detecting device 124 below the positioning hole 122. If the distance exceeds the set value, the top cover 103 is not completely restored, and an alarm is given at the moment.
