[0002] Battery casings typically refer to protective covers made of metal or plastic, used to encapsulate battery packs or power modules. Hook-and-loop fastening uses mechanical pressure to tightly engage hooks with the casing structure, achieving rapid fixation and sealing, avoiding the use of screws or welding, improving assembly efficiency and structural stability.

[0008] In a preferred embodiment, the detection assembly further includes: two movable blocks, which are respectively equidistantly fitted onto the outer walls of both ends of the bidirectional lead screw. U-shaped sliding plates are fixedly connected to the lower sides of the two movable blocks. The two U-shaped sliding plates are respectively located on both sides of the insertion square hole in the battery casing. Two limiting rods are fixedly connected at equal intervals to the sides of the two U-shaped sliding plates that are far apart from each other. The other ends of the two limiting rods located on the same U-shaped sliding plate pass through and slide against two limiting holes opened on the inner wall of the corresponding adjacent U-shaped detection chamber.

[0009] In a preferred embodiment, the detection component further includes: a sliding plate, two sliding plates being slidably connected inside the groove of the corresponding U-shaped sliding plate, one end of two telescopic springs being fixedly connected at equal intervals on one side of the two sliding plates, and the other end of the two telescopic springs being fixedly connected to the corresponding U-shaped sliding plate; and a pressure sensor, two pressure sensors being respectively disposed inside the corresponding U-shaped sliding plate, the force-bearing end of the pressure sensor abutting against the extrusion head disposed on one side of the corresponding sliding plate.

[0010] In a preferred embodiment, the anti-jamming component includes: a fixed base, fixedly connected to the upper side of the U-shaped detection chamber, a limiting groove plate fixedly connected to the upper side of the fixed base, and multiple sensing plates equally spaced embedded in the inner wall of the limiting groove plate; a contact plate, slidably connected to the inside of the limiting groove of the limiting groove plate, and multiple return springs are equally spaced and fixedly connected to one end of each return spring on the side of the contact plate near the sensing plate, the other end of each return spring being connected to the inner wall of the limiting groove plate.

When the front end of the hook is bent, it will first pass through the detection component before being inserted into the square hole. Due to the excessive bending of the front end of the hook, the excessively bent front end will contact and squeeze one of the sliding plates, so that the sliding plate overcomes the elastic force of the telescopic spring and the squeezing head on it will continuously squeeze the pressure sensor. When the pressure sensor reaches the preset value, it will trigger the alarm through the electrical signal to notify the staff to make adjustments. This avoids the situation where the bent hook is directly inserted into the square hole and forcibly fitted by the riveting machine, which would cause damage to the battery casing and the riveting machine due to irregular compression.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] The hook riveting mechanism disclosed in this utility model is mainly used in the production of existing power supply casings. Because it is impossible to detect whether the front end of the hook is bent before riveting, the deformed hook is forcibly riveted into the square hole, causing the battery casing and riveting equipment to be damaged due to abnormal force.

[0021] Reference Figures 1-3 A hook riveting mechanism for power supply casing production includes: a base 1, with a transfer turntable 2 connected to the upper outer wall of the base 1 via bearings, and a riveting machine 4 disposed above the base 1; a fixed platform 9, with multiple fixed platforms 9 fixedly connected at equal intervals to the upper side of the transfer turntable 2, and a battery casing body 3 placed on the upper side of each of the multiple fixed platforms 9; a perforated track 13, fixedly connected to the upper side of the fixed platform 9, and located on one side of the battery casing body 3; a detection component 12, slidably connected inside the perforated track 13, the detection component 12 being fixed to the perforated track 13 by bolts, the detection component 12 being used to detect whether the hook has bent before being riveted to the battery casing body 3; and an anti-jamming component 15, disposed on the detection component 12, the anti-jamming component 15 being used to prevent the detection component 12 from affecting the riveting of the hook and the battery casing body 3 that has not bent.

[0022] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the detection component 12 includes: a mounting frame 1206, slidably connected to the interior of the perforated track 13, a guide rod 1208 fixedly connected to one inner wall of the mounting frame 1206, and a sliding block 1205 slidably connected to the outer wall of the guide rod 1208; an electric telescopic rod 1204, disposed on the lower inner wall of the mounting frame 1206, the telescopic end of the electric telescopic rod 1204 being fixedly connected to the lower side of the sliding block 1205; and an alarm 1207, disposed on the upper end of the mounting frame 1206.

[0023] In this scheme, the detection component 12 further includes: a U-shaped detection chamber 1202, which is fixedly connected to the side of the sliding block 1205 away from the mounting frame 1206. One side of the U-shaped detection chamber 1202 abuts against the side of the insertion square hole opened in the battery casing body 3. Rotation holes are respectively opened on the inner walls of the upper two sides of the U-shaped detection chamber 1202. The same bidirectional lead screw 1212 is connected inside the two opposing rotation holes through bearings. An adjustment motor 1201 is fixedly connected to the side of the U-shaped detection chamber 1202 away from the mounting frame 1206. The drive end of the adjustment motor 1201 is connected to one end of the bidirectional lead screw 1212 through a coupling.

[0024] In this scheme, the detection component 12 further includes: a movable block 1209, two movable blocks 1209 are respectively equidistantly sleeved on the outer walls of both ends of the bidirectional lead screw 1212, and U-shaped sliding plates 1211 are respectively fixedly connected to the lower side of the two movable blocks 1209. The two U-shaped sliding plates 1211 are respectively on both sides of the insertion square hole opened on the battery casing body 3. Two limiting rods 1203 are respectively fixedly connected at equal intervals on the side of the two U-shaped sliding plates 1211 that are far apart from each other. The other ends of the two limiting rods 1203 located on the same U-shaped sliding plate 1211 pass through and slide on the two limiting holes opened on the inner wall of the corresponding adjacent U-shaped detection chamber 1202.

[0025] In this scheme, the detection component 12 further includes: a sliding plate 1214, two sliding plates 1214 are respectively slidably connected to the inside of the corresponding U-shaped slide plate 1211, one end of two telescopic springs 1213 are fixedly connected at equal intervals to one side of the two sliding plates 1214, and the other end of the two telescopic springs 1213 is fixedly connected to the corresponding U-shaped slide plate 1211; and a pressure sensor 1210, two pressure sensors 1210 are respectively disposed inside the corresponding U-shaped slide plate 1211, and the force-bearing end of the pressure sensor 1210 abuts against the extrusion head disposed on one side of the corresponding sliding plate 1214.

[0026] During riveting, the adjustment motor 1201 drives the bidirectional lead screw 1212 to rotate, adjusting the distance between the two U-shaped sliding plates 1211 according to the size of the insertion square hole. During this process, the bidirectional lead screw 1212 and the electric telescopic rod 1204 can be adaptively adjusted according to different models of battery casing 3, improving work efficiency. When the front end of the hook bends, the hook will first pass through the detection component 12 before entering the insertion square hole. Due to the excessive bending of the front end of the hook, the excessively bent front end will contact and squeeze one of the sliding plates 1214, causing the sliding plate 1214 to overcome the elasticity of the telescopic spring 1213 and cause the squeezing head on it to continuously squeeze the pressure sensor 1210. When the pressure sensor 1210 reaches the preset value, the alarm 1207 is triggered by the electrical signal to notify the staff to make adjustments, avoiding the situation where the bent hook is directly inserted into the square hole and forcibly engaged by the riveting machine 4, resulting in irregular squeezing and damage to the battery casing 3 and the riveting machine 4.

[0027] Reference Figure 2 , Figure 3 and Figure 5In a preferred embodiment, the anti-jamming component 15 includes: a fixed base 1505, fixedly connected to the upper side of the U-shaped detection chamber 1202, a limiting groove plate 1504 fixedly connected to the upper side of the fixed base 1505, and a plurality of sensing plates 1503 are embedded at equal intervals on the inner wall of the limiting groove plate 1504; a contact plate 1501, slidably connected to the inside of the limiting groove of the limiting groove plate 1504, and a plurality of return springs 1502 are fixedly connected at equal intervals on the side of the contact plate 1501 near the sensing plates 1503, and the other ends of the plurality of return springs 1502 are connected to the inner wall of the limiting groove plate 1504.

[0028] During riveting, the hook passes normally through the detection component 12. At this time, the pusher 5 will contact and squeeze the contact plate 1501 in the anti-jamming component 15, causing the contact plate 1501 to overcome the elastic force of the return spring 1502 and move towards the sensing plate 1503. When the contact plate 1501 contacts the sensing plate 1503, it proves that the hook is normal. Then, the sensing plate 1503 controls the electric telescopic rod 1204 through an electrical signal to raise the detection unit, so as to avoid the hook not reaching the riveting position due to the obstruction of the detection unit.

[0029] Reference Figure 1 and Figure 2 In a preferred embodiment, an L-shaped baffle 14 is fixedly connected to the upper side of the fixed platform 9, the battery casing body 3 is located between the L-shaped baffle 14 and the perforated track 13, a front cylinder 10 is provided on the upper side of the fixed platform 9, a front pressure plate 11 is fixedly connected to the telescopic end of the front cylinder 10, the front pressure plate 11 abuts against the front end of the battery casing body 3, a side pressure cylinder 8 is embedded inside the L-shaped baffle 14, the telescopic end of the side pressure cylinder 8 passes through the inner wall of the L-shaped baffle 14 and is connected to a side pressure plate 7, the side pressure plate 7 abuts against one side of the battery casing body 3, a track frame 6 is provided on one side of the base 1, and a pusher gripper 5 is provided inside the track frame 6.

[0030] When using the hook riveting mechanism for power supply casing production, the battery casing body 3 to be riveted is first placed on the fixed platform 9. Then, according to the model of the battery casing body 3, the side pressure plate 7 and the front pressure plate 11 corresponding to the side pressure cylinder 8 and the front pressure cylinder 10 are adjusted to clamp and fix the battery casing body 3, so as to prevent the battery casing body 3 from moving during riveting.

[0031] Working principle: When the operator uses the hook riveting mechanism for power supply casing production, the battery casing body 3 to be riveted is conveyed from the previous station and placed on the fixed table 9. Then, the fixed table 9 adjusts the side pressure plate 7 and the front pressure plate 11 corresponding to the side pressure cylinder 8 and the front pressure cylinder 10 according to the model of the battery casing body 3 to adaptively clamp and fix the battery casing body 3, preventing the battery casing body 3 from moving during riveting. Then, the detection component 12 is slid along the perforated track 13 until one side of the U-shaped detection chamber 1202 is aligned with the battery casing body. After one side of the insertion square hole is abutted, the detection component 12 is fixed to the perforated track 13 with bolts. Then, the adjusting motor 1201 is turned on to drive the bidirectional lead screw 1212 to rotate and adjust the distance between the two U-shaped slide plates 1211 according to the size of the insertion square hole. During this process, the bidirectional lead screw 1212 and the electric telescopic rod 1204 can be adjusted to adapt to different models of battery casing body 3, improving work efficiency. After everything is ready, the pusher 5 pushes the hook through the insertion square hole until it reaches the riveting position. The riveting machine 4 is used to rivet the two riveting points on the hook to engage with the battery casing body 3. When the front end of the hook bends, the hook will first pass through the detection component 12 before passing through the insertion square hole. Due to the excessive bending of the front end of the hook, the excessively bent front end will contact and press against one of the sliding plates 1214, causing the sliding plate 1214 to overcome the elastic force of the telescopic spring 1213 and cause the pressing head on it to continuously press the pressure sensor 1210. When the pressure sensor 1210 reaches the preset value, the alarm 1207 is triggered by an electrical signal. Notify staff to make adjustments; when the front end of the hook does not bend, the hook passes normally through the detection component 12. At this time, the pusher 5 will contact and squeeze the contact plate 1501 in the anti-jamming component 15, causing the contact plate 1501 to overcome the elastic force of the return spring 1502 and move towards the sensing plate 1503. When the contact plate 1501 contacts the sensing plate 1503, it proves that the hook is normal. Then the sensing plate 1503 controls the electric telescopic rod 1204 through the electrical signal to raise the detection unit, so as to avoid the hook not reaching the riveting position due to the obstruction of the detection unit.
