DETAILED DESCRIPTION

[0027] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] Please refer to Figures 1 to 8A tray-type side seam welding fixture comprises a frame 1, a tray 6, an end pressing mechanism 5 and a side pressing mechanism 4, wherein: the tray 6 is detachably arranged on the frame 1; the end pressing mechanism 5 is adjustably arranged on the tray 6; and the side pressing mechanism 4 is adjustably arranged on the tray 6. Figure 1 and Figure 3 As shown, two end pressing mechanisms 5 are mirror-imaged in the first direction X, and two side pressing mechanisms 4 are mirror-imaged in the second direction Y. The space defined by the two end pressing mechanisms 5 and the two side pressing mechanisms 4 is used to place the battery 3. The side plate of the battery 3 is positioned by the side pressing mechanism 4, and the end plate of the battery 3 is positioned by the end pressing mechanism 5. In this embodiment, by integrating the end pressing mechanism 5 and the side pressing mechanism 4 on the tray 6, when the product is changed, the tray 6 can be removed from the frame 1 as a whole and replaced. The adjustment process after the replaced tray 6 is assembled with the frame 1 is simple, which can effectively improve the work efficiency.

[0031] In this embodiment, the end pressing mechanism 5 can be any existing end pressing mechanism 5 for positioning the end plate of the battery 3; similarly, the side pressing mechanism 4 can be any existing side pressing mechanism 4 for positioning the side plate of the battery 3.

[0032] In this embodiment, the adjustment of the tray 6 on the rack 1 mainly involves the positioning of the tray 6 on the rack 1. Based on this, Figure 2 As shown, the frame 1 is provided with a longitudinal positioning member 20 and a transverse positioning member 21, the lower side of the tray 6 is provided with a first positioning portion (not shown in the figure) adapted to the longitudinal positioning member 20, and the periphery of the tray 6 is provided with a second positioning portion 61 adapted to the transverse positioning member 21. The longitudinal positioning member 20 is used to provide support and positioning for the tray 6 in the longitudinal direction Z, and the transverse positioning member 21 is used to provide support and positioning for the tray 6 in the transverse direction, so that the tray 6 can be quickly and accurately positioned and assembled on the frame 1.

[0033] It should be noted that if Figure 1 and Figure 2 As shown, the longitudinal direction Z in this embodiment is a direction perpendicular to the ground, and the transverse direction is parallel to the plane where the first direction X and the second direction Y are located, that is, the transverse direction is a direction parallel to the ground.

[0034] Furthermore, if Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the longitudinal positioning member 20 includes a supporting portion 207, and the supporting portion 207 is at least one of a positioning block, a positioning pin or a positioning groove. Preferably, the supporting portion 207 is a positioning block, and accordingly, the first positioning portion is a groove-shaped structure.

[0035] It is understandable that in other embodiments, when the support portion 207 is a positioning pin, the first positioning portion is a hole-shaped structure that cooperates with the positioning pin; when the support portion 207 is a positioning groove, the first positioning portion is a protrusion structure that cooperates with the positioning groove. The shape of the support portion 207 is not limited, as long as it can cooperate with the corresponding first positioning portion to position the assembly tray 6.

[0036] like Figure 1 , Figure 2 and 5 to Figure 7 As shown, the longitudinal positioning member 20 further includes a first adjustment plate 201 and a second adjustment plate 202, wherein: the first adjustment plate 201 can move relative to the frame 1 along a first direction X; the second adjustment plate 202 can move relative to the second adjustment plate 202 along a second direction Y; the first direction X is perpendicular to the second direction Y, and the first direction X and the second direction Y are both parallel to the lower side of the tray 6; and the support portion 207 is disposed on the second adjustment plate 202. The first adjustment plate 201 and the second adjustment plate 202 constitute the main structure of the longitudinal positioning member 20, and the tray 6 is assembled on the second adjustment plate 202 through the support portion 207. When an external force acts on the tray 6, the tray 6 can be spatially adjusted in the first direction X and the second direction Y in the manner that the first adjustment plate 201 moves in the first direction X and the second adjustment plate 202 moves in the second direction Y, so that the tray 6 and the end pressure mechanism 5 and the side pressure mechanism 4 installed on the tray 6 can be positionally adjusted after being installed on the frame 1 to adapt to the spatial position requirements under a specific processing environment. It can be understood that the adjustment method through the first adjustment plate 201 and the second adjustment plate 202 is to further adjust the position of the tray 6 based on the support part 207 cooperating with the first positioning part to position the tray 6, so as to adapt to different processing environment requirements and improve the positioning and assembly accuracy. The operation is simple and conducive to improving work efficiency.

[0037] Furthermore, the frame 1 is provided with a first stopper 2081 and a second stopper 209, the first stopper 2081 is close to one end of the first adjustment plate 201 in the first direction X, and the second stopper 209 is close to the other end of the first adjustment plate 201 in the first direction X; a first reset member 2083 is pressed between the first stopper 2081 and the first adjustment plate 201, and under normal conditions, the first reset member 2083 acts on the first adjustment plate 201 to abut against the second stopper 209. Figure 2 and Figure 7As shown, a mounting plate 2 is mounted on the frame 1, and the longitudinal positioning member 20 and the transverse positioning member 21 are both mounted on the mounting plate 2. By integrating the longitudinal positioning member 20 and the transverse positioning member 21 on the mounting plate 2, it is advantageous to realize the modularization of the tray-type side seam welding fixture, and facilitate the rapid disassembly and assembly of the tray-type side seam welding fixture. The first limiting member 2081 and the second limiting member 209 are used to limit the adjustment range of the first adjustment plate 201 in the first direction X. The normal state here refers to the state in which the first adjustment plate 201 is not subjected to external force in the first direction X.

[0038] During use, when the tray 6 is replaced during a product change process, under the action of the first restoring member 2083 , the first adjustment plate 201 always maintains a state of abutting against the second limiting member 209 .

[0039] Similarly, the first adjustment plate 201 is provided with a third stopper 2062 and a fourth stopper 205, wherein the third stopper 2062 is close to one end of the second adjustment plate 202 in the second direction Y, and the fourth stopper 205 is close to the other end of the second adjustment plate 202 in the second direction Y; in a normal state, a second reset member 2063 is pressed between the third stopper 2062 and the second adjustment plate 202, and the second reset member 2063 acts on the second adjustment plate 202 to abut against the fourth stopper 205. The third stopper 2062 and the fourth stopper 205 are used to limit the adjustment range of the second adjustment plate 202 in the second direction Y. The normal state here refers to the state in which the second adjustment plate 202 is not acted upon by external forces in the second direction Y. When in use, when the tray 6 is replaced during the product change process, under the action of the second reset member 2063, the second adjustment plate 202 always maintains a state of abutting against the fourth stopper 205. In this way, under the joint action of the first reset member 2083 and the second reset member 2063, the total positioning member can maintain a fixed spatial position on the frame 1 before the pallet 6 is assembled, which is conducive to quickly assembling the pallet 6 to the frame 1, that is, the longitudinal positioning member 20, through automated equipment such as a robotic arm.

[0040] like Figures 5 to 7 As shown, the mounting plate 2 is provided with a first slide rail 2031, which extends along the first direction X, and the first adjustment plate 201 is provided with a first slider 2032 adapted to the first slide rail 2031, and the first slider 2032 cooperates with the first slide rail 2031 to enable the first adjustment plate 201 to move in the first direction X; further, the first adjustment plate 201 is provided with a second slide rail 2041, which extends along the second direction Y, and the second adjustment plate 202 is provided with a second slider 2042 adapted to the second slide rail 2041, and the second slider 2042 cooperates with the second slide rail 2041 to enable the second adjustment plate 202 to move in the second direction Y.

When in use, the second adjustment plate 202 can abut against the second limiting pin 2052, i.e., the fourth limiting member 205, under the action of the second reset member 2063.

[0049] like Figures 1 to 3 and Figure 7 As shown, the transverse positioning member 21 includes a first driving member 211, a first support plate 212 and a clamping portion 213, wherein: the first support plate 212 can move relative to the frame 1 along the second direction Y; the clamping portion 213 can move relative to the first support plate 212 along the first direction X; the first driving member 211 is installed on the frame 1, and is used to drive the first support plate 212 to move along the second direction Y, so as to drive the clamping portion 213 to approach or move away from the second positioning portion 61.

[0050] like Figure 1 As shown, when in use, the tray 6 is first placed on the frame 1, the supporting portion 207 is matched with the first positioning portion to realize the pre-assembly of the tray 6, and then the tray 6 is driven to adjust the spatial position of the tray 6 in the second direction Y to a predetermined position in such a manner that the second adjustment plate 202 moves along the second direction Y; then the first support plate 212 and the clamping portion 213 provided on the first support plate 212 are driven by the first driving member 211 to move toward the second positioning portion 61 until the clamping portion 213 is clamped to the second positioning portion 61; finally, the tray 6 is driven to adjust the spatial position of the tray 6 in the first direction X to a predetermined position in such a manner that the first adjustment plate 201 moves along the first direction X.
