[0002] The lithium battery casing includes an upper cover and a lower cover. When assembling the upper cover and the lower cover, they need to be assembled through installation equipment. During assembly, the lower cover is placed in the installation equipment and the upper cover is placed on the lower cover. Thereafter, the upper cover is pressed by a pneumatic cylinder to assemble the upper cover on the lower cover to complete the assembly.

[0003] For example, a glass insulator pre-assembly pressing device with publication number CN214123611U includes a pressing mechanism, a cylinder located above the pressing mechanism, a vibrator fixed on the pressing mechanism, and a signal control system. The pressing mechanism acts on the glass insulator; the cylinder controls the up and down movement of the pressing mechanism; the vibrator provides vibration force, and transmits the vibration to the glass insulator body through the pressing mechanism; the signal control system is controlled by PLC according to the travel position of the glass insulator on the conveyor belt, guiding the reciprocating movement of the cylinder, thereby driving the reciprocating movement of the pressing hook.

[0004] The use principle of this device is the same as that of the above-mentioned device, but this device cannot well control the force of the pneumatic cylinder when assembling the product, so there is a situation of crushing parts and increasing the scrap rate. Utility Model Content

[0005] The utility model provides a lithium battery pack housing installation device, which can prevent the upper cover from being over-pressed when the installation device assembles the upper cover and the lower cover, thereby reducing the scrap rate.

[0006] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a lithium battery pack casing installation device, characterized in that it includes a body and a pressure plate slidably connected to the body, an assembly cavity is formed between the bottom surface of the body and the pressure plate, when the upper cover and the lower cover are located in the assembly cavity, the pressure plate presses the upper cover on the lower cover to complete the assembly, and sliding rods are fixedly connected to both side walls of the assembly cavity, and a limiting plate is slidably connected between the two sliding rods and below the pressure plate. When the pressure plate is pressed down, the limiting plate is located between the upper cover and the pressure plate and limits the lowest pressing position of the pressure plate. The sliding rod is located below the limiting plate and is slidably connected to a clamping block that is on the same horizontal plane as the top end of the upper cover. When the pressure plate is pressed down, the limiting plate slides down and forms abutment with the clamping block.

[0007] A further preferred technical solution of the utility model is: embedding grooves are provided on both side walls of the assembly cavity, and the sliding rods are fixedly connected in the embedding grooves.

[0008] A further preferred technical solution of the utility model is: a slide groove is provided on the two slide rods, and two ends of the limiting plate extend into the slide grooves of the two slide rods respectively.

[0009] A further preferred technical solution of the utility model is: a spring is fixedly connected between the top surface of the limiting plate and the top surface of the inner side of the slide groove, and when the limiting plate slides down along with the pressure plate, the spring is deformed.

[0010] A further preferred technical solution of the utility model is: the clamping block is a bolt, and the bolt is rotatably connected to an abutment block which is located in the slide groove and can form an abutment with the inner wall of the slide groove. When the limiting plate abuts with the upper cover, the abutment block and the limiting plate abut against each other. The abutment block is a rectangular block. When the bolt rotates, the abutment block slides back and forth in the slide groove.

[0011] A further preferred technical solution of the utility model is: a side wall of the abutment block is fixedly connected with an anti-skid pad that can abut against the inner wall of the slide groove, and the anti-skid pad is elastic.

[0012] A further preferred technical solution of the utility model is: a slide plate is slidably connected to the bottom surface of the assembly cavity.

[0013] A further preferred technical solution of the utility model is: a pneumatic cylinder for pushing a pressure plate to slide is fixedly connected to the top surface of the machine body, and a linear slide rail with one end extending into the assembly cavity is fixedly connected to both sides of the pneumatic cylinder of the machine body, and the pressure plate slides along the linear slide rail.

[0014] A further preferred technical solution of the utility model is: a solenoid valve electrically connected to the pneumatic cylinder is fixedly connected to one side wall of the body, and a pedal switch electrically connected to the pneumatic cylinder is arranged outside the body.

[0015] A further preferred technical solution of the utility model is: a self-locking switch is fixedly connected to a side wall of the body away from the solenoid valve, and a switching power supply electrically connected to the self-locking switch is fixedly connected to a side wall of the body away from the opening of the assembly chamber.

[0016] Compared with the prior art, the utility model forms an assembly cavity between the bottom surface of the body and the pressure plate, and sliding rods are fixedly connected to the two side walls of the assembly cavity, and a limiting plate is slidably connected between the two sliding rods and located below the pressure plate. The sliding rod is slidably connected to a clamping block which is on the same horizontal plane as the top of the upper cover under the limiting plate. Therefore, when the upper cover and the lower cover are assembled, as the pressure plate moves downward, the pressure plate and the limiting plate form abutment. At this time, the limiting plate contacts the upper cover under the push of the pressure plate and presses the upper cover onto the lower cover until the limiting plate and the clamping block form abutment. At this time, the clamping block can effectively prevent the pressure plate and the limiting plate from continuing to press downward, thereby protecting the assembled shell, reducing the possibility of waste generation, and thus reducing the waste rate.

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0027] Figure 1-Figure 6As shown, a lithium battery pack casing installation device includes a body 1 and a pressing plate 2 slidably connected to the body 1, the pressing plate 2 is a PU pressing plate 2, the top surface of the body 1 is fixedly connected to a pneumatic cylinder 6 for pushing the pressing plate 2 to slide, the body 1 is located on both sides of the pneumatic cylinder 6 and is fixedly connected to a linear slide rail 7 with one end extending into an assembly cavity 11, the pressing plate 2 slides along the linear slide rail 7, and an assembly cavity 11 is formed between the bottom surface of the body 1 and the pressing plate 2, a solenoid valve 5 electrically connected to the pneumatic cylinder 6 is fixedly connected to a side wall of the body 1, and a pedal switch 9 electrically connected to the pneumatic cylinder 6 is provided outside the body 1.

[0028] Therefore, when it is necessary to assemble the upper cover 3 and the lower cover 4, the upper cover 3 and the lower cover 4 are placed in the assembly chamber 11. At this time, the pedal switch 9 is stepped on, and the pedal switch 9 starts the solenoid valve 5. At this time, the solenoid valve 5 controls the output end of the pneumatic cylinder 6 to push the pressure plate 2 to slide downward along the linear slide rail 7. At this time, the assembly chamber 11 becomes smaller, and during the sliding process, the bottom surface of the pressure plate 2 contacts the top surface of the upper cover 3 and pushes the upper cover 3 to move downward, so that the upper cover 3 is inserted into the lower cover 4 to complete the assembly. Thereafter, the solenoid valve 5 controls the output end of the pneumatic cylinder 6 to move upward and reset, and the pressure plate 2 is also reset. At this time, the assembly chamber 11 becomes larger, which is convenient for taking out the assembled upper cover 3 and the lower cover 4.

[0029] A pressure regulating switch 13 is provided between the solenoid valve 5 and the pneumatic cylinder 6. When installing upper covers 3 and lower covers 4 of different types, the sliding range of the output end of the pneumatic cylinder 6 can be adjusted by the pressure regulating switch 13, so that the device can be suitable for the assembly of upper covers 3 and lower covers 4 of different types.

[0030] A self-locking switch 8 is fixedly connected to a side wall of the body 1 away from the solenoid valve 5, and a switching power supply 12 electrically connected to the self-locking switch 8 is fixedly connected to a side wall of the body 1 away from the opening of the assembly chamber 11. Therefore, after the upper cover 3 and the lower cover 4 are assembled, the device can be turned off by turning off the switching power supply 12, thereby avoiding accidental touching of the pedal switch 9 to cause the device to start when not in use. When in use, start the switching power supply 12 and press the self-locking switch 8. At this time, the self-locking switch 8 can ensure that the switching power supply 12 is always turned on when the upper cover 3 and the lower cover 4 are assembled, thereby facilitating subsequent long-term assembly.

[0031] Slide rods 15 are fixedly connected to both side walls of the assembly cavity 11, and a limiting plate 14 is slidably connected between the two slide rods 15 and located below the pressure plate 2. When the pressure plate 2 is pressed downward, the limiting plate 14 is located between the upper cover 3 and the pressure plate 2 and limits the lowest downward position of the pressure plate 2. The slide rod 15 is located below the limiting plate 14 and is slidably connected to a block that is on the same horizontal plane as the top of the upper cover 3.

[0032] Therefore, when the pressure plate 2 slides downward, the pressure plate 2 and the top surface of the limiting plate 14 form abutment. At this time, the pressure plate 2 pushes the limiting plate 14 to slide downward as well, until the bottom surface of the limiting plate 14 forms abutment with the top surface of the upper cover 3. At this time, the limiting plate 14 pushes the upper cover 3 to slide downward until the two ends of the limiting plate 14 form abutment with their corresponding blocks. At this time, the limiting plate 14 and the pressure plate 2 are both located at the lowest point within their sliding range, and the upper cover 3 is inserted into the lower cover 4 to complete the assembly. This design limits the lowest point at which the pressure plate 2 can slide, thereby avoiding damage to the upper cover 3 or the lower cover 4 caused by excessive pressure from the pressure plate 2, thereby protecting the upper cover 3 and the lower cover 4, thereby reducing the scrap rate, and the limiting plate 14 can increase the contact area, thereby better limiting the sliding range of the pressure plate 2.

[0033] Both side walls of the assembly cavity 11 are provided with embedding grooves 18 , and the slide rod 15 is fixedly connected in the embedding grooves 18 . This design can prevent the slide rod 15 from protruding and affecting the sliding of the pressure plate 2 , thereby playing the role of hiding the slide rod 15 .

[0034] A slide groove 17 is provided on the two slide bars 15, and the two ends of the limiting plate 14 extend into the slide grooves 17 of the two slide bars 15 respectively. A spring 16 is fixedly connected between the top surface of the limiting plate 14 and the top surface of the slide groove 17. When the limiting plate 14 slides down with the pressure plate 2, the spring 16 is deformed due to the force. When the pressure plate 2 is reset driven by the output end of the pneumatic cylinder 6, the deformed spring 16 drives the limiting plate 14 to reset, thereby facilitating the next use. This design plays a role in driving the limiting plate 14 to reset.

[0035] The clamping block is a bolt 19, and an abutting block 20 is rotatably connected to the bolt 19 and is located in the slide groove 17 and can form an abutment with the inner wall of the slide groove 17. When the limiting plate 14 abuts with the upper cover 3, the abutting block 20 and the limiting plate 14 abut against each other. The abutting block 20 is a rectangular block to prevent the abutting block 20 from rotating when the bolt 19 rotates. When the bolt 19 rotates, the abutting block 20 slides back and forth in the slide groove 17.

[0036] Therefore, when assembling the upper cover 3 and the lower cover 4 of different sizes, the bolt 19 is rotated. At this time, as the bolt 19 is rotated, the abutment block 20 slides along the slide groove 17 toward the end away from the limiting plate 14, and releases the abutment with the inner wall of the slide groove 17 during the sliding process. At this time, the bolt 19 can be moved according to the highest point of the assembled upper cover 3 of the size, so that the top surface of the abutment block 20 and the highest point of the upper cover 3 are on the same horizontal plane, which is the lowest point that the pressure plate 2 can move. The bolt 19 is further rotated in the opposite direction so that the abutment block 20 abuts against the inner wall of the slide groove 17, thereby fixing the bolt 19 and the abutment block 20. The position of the abutment block 20 of this design can be adjusted according to the size of the upper cover 3 and the lower cover 4, so that the equipment is suitable for the assembly of upper covers 3 and lower covers 4 of different sizes.

[0037] A non-slip pad is fixedly connected to one side wall of the abutment block 20 and can abut against the inner wall of the slide groove 17. The non-slip pad is elastic and increases the friction between the abutment block 20 and the inner wall of the slide groove 17, thereby improving the supporting effect of the abutment block 20 and preventing it from sliding.

[0038] A slide plate 10 is slidably connected to the bottom surface of the assembly cavity 11. When the upper cover 3 and the lower cover 4 are placed, the upper cover 3 and the lower cover 4 are placed on the slide plate 10. When the assembled upper cover 3 and the lower cover 4 need to be replaced, the assembled upper cover 3 and the lower cover 4 can be taken out by sliding the slide plate 10, thereby facilitating replacement.

[0039] The above is an introduction to a lithium battery pack housing installation device provided by the utility model. This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
