DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 5 , the utility model proposes a battery restraint machine.

[0027] The battery restraint machine includes a machine 100, a restraint assembly and a pressure mechanism. A front push plate 210 and a rear side plate 300 extend upward from both sides of the machine 100. A horizontally placed guide rod 400 is provided between the front push plate 210 and the rear side plate 300. A pressure mechanism mounting frame 500 is installed on the machine 100. First linear guide rails 510 are provided on both sides of the pressure mechanism mounting frame 500. The restraint assembly includes a plurality of restraint plates 600 arranged in parallel and at intervals. The two ends of the restraint plates 600 are slidably connected to the guide rods 400, and the space between two adjacent restraint plates 600 is used for Place the battery 110; the pressure-applying mechanism includes a servo motor 710, a reducer 720, a ball screw 730 and a nut holder 800. The servo motor 710 drives the reducer 720, and the reducer 720 is connected to the ball screw 730. The opposite sides of the nut holder 800 are slidably connected to the first linear guide rails 510 on both sides. The ball screw 730 is threadedly connected to the nut holder 800, and when the ball screw 730 rotates, it can drive the nut holder 800 to move. The nut holder 800 can press the front push plate 210 to move, thereby applying pressure to one end of the restraint assembly.

[0028] Specifically, the battery 110 is clamped between two adjacent restraint plates 600, and pressure can be applied to the battery 110 through the two restraint plates 600. The battery 110 can be a blade battery 110 or other square battery 110. The restraint plates 600 are arranged in parallel, and the servo motor 710 outputs torque to the ball screw 730 through the reducer 720 to rotate, and then transmits it to the nut holder 800, driving the nut holder 800 to move and push it to the front push plate 210. The movement of the front push plate 210 gradually reduces the spacing between the restraint plates 600, squeezing the battery 110 and completing the restraint and pressurization of the battery 110. The present invention is precisely controlled by the servo motor 710, and the torque is increased by the reducer 720, so that the ball screw 730 rotates to drive the nut 800 to move, and pushes the front push plate 210 to move, so that the battery 110 is pressurized between each restraint plate 600. Since the servo motor 710 drives the battery 110, the control accuracy is higher, and the battery 110 can be placed in the optimal pressure production range. At the same time, since the servo motor 710 and the reducer 720 cooperate to increase the torque, the pressure applied by the front push plate 210 to the restraint plate 600 can be greatly improved, so as to achieve the quality of pressurizing the blade battery 110 and ensure the restraint and pressurization effect of the battery restraint machine on the battery 110.

[0029] See also Figures 1 to 2Furthermore, a second linear guide rail 820 is installed on both sides of the nut seat 800, and a slidable slider 830 is provided on the second linear guide rail 820. The slider 830 is connected to the tightening rod fixing block 840, and the tightening rod fixing block 840 is connected to the call-back cantilever 850. A driving member 860 is installed on the nut seat 800, and the driving member 860 drives the call-back cantilever 850. The call-back cantilever 850 can hook the back side of the front push plate 210 away from the nut seat 800 to pull the front push plate 210 back. Specifically, when it is necessary to release the restraint, the driving members 860 on both sides of the nut seat 800 respectively drive the left and right movement of the return cantilever 850, so that the return cantilever 850 can be buckled into the rear side of the front push plate 210, that is, the side facing the rear side plate 300. At this time, the servo motor 710 reverses and drives the ball screw 730 to rotate in the opposite direction through the reducer 720, so that the front push plate 210 is pulled back and then drives each restraint plate 600 to be pulled back, releasing the pressure of the restraint plate 600 on the battery 110. When it is necessary to restrain the battery 110, the return cantilever 850 can also be set on the rear side of the front push plate 210, as long as the return cantilever 850 does not hinder the movement of the front push plate 210.

[0030] See also Figures 1 to 2 Furthermore, the driving member 860 includes a cylinder 861 and a connecting plate of the cylinder 861. The output end of the cylinder 861 drives and connects to the connecting plate of the cylinder 861, and the connecting plate of the cylinder 861 is connected to the return cantilever 850. Specifically, the output end of the cylinder 861 can telescopically drive the connecting plate of the cylinder 861, thereby enabling the connecting plate of the cylinder 861 to drive the return cantilever 850 to move left and right, so that the return cantilever 850 can switch back and forth between the position of being buckled into the front push plate 210 and the position of being disengaged from the front push plate 210.

[0031] See also Figures 1 to 2 Furthermore, the shape of the dial-back cantilever 850 is L-shaped. The dial-back cantilever 850 only needs to be able to hook the front push plate 210 and drive it to move back.

[0032] See also Figures 2 to 5 Furthermore, a hook groove 870 is provided on the side of the front push plate 210 away from the nut seat 800, and the hook groove 870 is used for hooking the return cantilever 850. The return cantilever 850 can be bent and hooked into the hook groove 870 of the front push plate 210, so that the return cantilever 850 can drive the front push plate 210 to move back.

[0033] See also Figures 1 to 2 Furthermore, a screw support bearing 880 is provided on the pressure mechanism mounting frame 500, and the end of the ball screw 730 is rotatably connected to the screw support bearing 880. The screw support bearing 880 can support the ball screw 730.

[0034] See also Figures 1 to 2 Furthermore, pressure push rods 890 extend forward from both sides of the nut holder 800. The pressure push rods 890 are used to press the front push plate 210 forward. The return cantilever 850 can be set further back than the pressure push rods 890. When the nut holder 800 moves forward, the nut holder 800 can drive the return cantilever 850 and the pressure push rods 890 to move forward, so that the pressure push rods 890 can push the front push plate 210, causing it to move toward the compression restraint plate 600.

[0035] See also Figures 3 to 5 Furthermore, a front plate 220 and a restraining block 230 are provided on the side of the front push plate 210 facing away from the rear side plate 300. The restraining block 230 is provided between the front plate 220 and the front push plate 210. Avoidance holes 221 are provided on the front plate 220 and the restraining block 230. The pressure push rod 890 can pass through the avoidance holes 221 and then support the front push plate 210. Specifically, when the nut holder 800 moves forward, the pressure push rod 890 first extends into the avoidance holes 221 of the front plate 220 and the restraining block 230 until it presses against the front push plate 210, causing the pressure push rod 890 to push the front push plate 210 to move, thereby restraining the battery 110.

[0036] The battery restraint machine of the present invention can be used to restrain the battery 110 in a variety of types. Furthermore, the battery 110 is a blade battery 110. Of course, the battery 110 can also be other square batteries 110.

[0037] See also Figures 1 to 2 To enable the nut holder 800 to move, a slide rail 511 is further provided at the bottom of the nut holder 800. The slide rail 511 is slidably connected to the first linear guide rail 510. When the ball screw 730 rotates, the nut holder 800 can move with the rotation of the ball screw 730. The nut holder 800 moves back and forth on the slide rail 511, allowing the nut holder 800 to slide on the first linear guide rail 510, so that the pressure push rod 890 on the nut holder 800 pushes the front push plate 210, completing the restraint of the battery 110.
