Description

Technical Field

[0001] The utility model belongs to the technical field of thermal batteries, and particularly relates to an assembly device for a thermal battery stack cylinder body. Background Art

[0002] A thermal battery is a primary reserve battery that uses molten salt as an electrolyte and is activated by melting it with its own heat source. It has the advantages of short activation time, wide operating ambient temperature, long storage period, and maintenance-free, and is increasingly widely used in weapon equipment systems.

[0003] When the thermal battery works, an external electrical signal or mechanical force is used to make the igniter inside the battery ignite. The fire source of the igniter is guided to the heating sheet inside the battery through an ignition strip, so that the single battery reaches its operating temperature, heating and melting the solid electrolyte that is non-conductive at normal temperature into an ionic conductor, and an electrochemical reaction occurs between the positive and negative electrodes to generate electric energy.

[0004] Assembling the thermal battery stack into the thermal battery cylinder body is an important process in thermal battery production. The feeding rate and pressure have a great influence on the battery performance. At present, when the thermal battery stack is assembled into the thermal battery cylinder body, it is purely manual, and a lead screw slider is used to press the battery stack into the thermal battery cylinder body without relevant control measures. At present, when the thermal battery stack is assembled into the thermal battery cylinder body, the specific operation steps include: manually first loading the bottom of the thermal battery stack into the thermal battery cylinder body, then placing the thermal battery stack and the cylinder body under the lead screw slider, and rotating the handle of the lead screw slider to forcibly press the thermal battery stack into the thermal battery cylinder body.

[0005] Using pure manual labor to assemble the thermal battery stack into the thermal battery cylinder body without pressure and rate control, the quality consistency and stability cannot be guaranteed, and the mass production requirements cannot be met. Therefore, an assembly device for a thermal battery stack cylinder body that improves production efficiency is needed.

[0006] The patent document with the publication number of CN107994174A discloses a miniaturized integrated assembly device for a thermal battery, including a base and a horizontal U-shaped bracket. The lower end of the bracket is fixedly connected to the base, and the upper end is connected with a clamping device. The base is fixedly connected with a lead screw, the upper end of the lead screw is fixedly connected with a lower pressing plate, the clamping device is connected with an upper pressing plate, and a handwheel is spirally connected to the lead screw. A placement groove for vertically placing the battery shell is arranged at the upper end of the handwheel. This patent uses manual assembly, and no corresponding sensors are provided on the device, and the problems of pressure and rate control in the assembly of the thermal battery stack cylinder body cannot be solved.

[0007] The patent document with the announcement number CN113725456A discloses a new energy battery overall downward pressure assembly device, including an assembly device body for fixing a battery box to realize the overall downward pressure assembly of the battery body into the battery box, the assembly device body includes a sliding seat and a camera visual judgment system arranged above the sliding seat, the camera visual judgment system can judge whether the battery box is fixed at a preset position and whether the posture is correct; a positioning component is arranged on the sliding seat, the positioning component includes a fixed plate fixed at a position near one end of the sliding seat, a sliding plate arranged near the other end of the sliding seat and arranged at a relative spacing with the fixed plate, and a clamping plate symmetrically arranged near the two sides of the sliding seat; the sliding plate can be relative to the fixed plate. The two clamping plates can be synchronously relative to each other. The fixed plate, the sliding plate and the two clamping plates clamp the fixed battery box together; the speed and accuracy of the fixed battery box can be effectively improved, the positioning is firm, and the battery box is fixed in the correct posture. However, the device has no structure adapted to the assembly of the cylinder, and no corresponding sensor is arranged on the device, which fails to solve the pressure and rate control problems in the assembly of the cylinder of the thermal battery stack.

Detailed Embodiments

[0025] The technical solutions of the present utility model will be further described below, but the scope of protection is not limited thereto.

[0026] Embodiment:

[0027] As Figures 1 to 4As shown in the figure, a thermal battery stack cylinder assembly device includes a frame body 1, an electric cylinder mechanism 2, a detection and sensing mechanism 3, a control device 4, and a height pre-adjustment mechanism 5. The frame body 1 includes a base 11 and a support frame 12. The base 11 is connected to the electric cylinder mechanism 2. Universal wheels 13 are provided at the bottom of the base 11. The support frame 12 is connected to the detection and sensing mechanism 3 through the height pre-adjustment mechanism 5. The control device 4 is connected to the base 11.

[0028] The frame body 1 is used for the installation and placement of other mechanisms; the electric cylinder mechanism 2 is a feeding mechanism for the thermal battery stack to enter the cylinder, enabling the battery stack to enter the cylinder normally; the detection and sensing mechanism 3 is used for adjusting the pressure and feeding rate of the thermal battery stack entering the cylinder; the control device 4 is used for human-machine interaction, setting and displaying relevant parameters. The operator can view relevant data on the display screen 41 and set the parameters of the cylinder entry pressure and cylinder entry rate through the key area 42. A control system is provided inside for controlling the cylinder entry pressure and cylinder entry rate of the thermal battery stack; the height pre-adjustment mechanism 5 is used for pre-adjusting the operating height space for the battery stack to enter the cylinder. The operator pre-adjusts the height to a suitable height according to the height of the thermal battery stack and the cylinder being operated.

[0029] A chamber 14 and a workbench surface 15 are provided on the base 11. A chamber door 16 is hinged on the chamber 14. The workbench surface 15 is arranged on the top of the base 11. The electric cylinder mechanism 2 includes a servo electric cylinder 21. The servo electric cylinder 21 is connected to the inner wall of the chamber 14 through an electric cylinder mounting base 22.

[0030] The detection and sensing mechanism 3 includes a pressure sensor 31 and a proximity sensor 32. The proximity sensor 32 is connected to the height pre-adjustment mechanism 5. The pressure sensor 31 is connected to the electric cylinder mechanism 2. The proximity sensor 32 is installed in the upper pressing block 54 of the height pre-adjustment mechanism 5. When the thermal battery stack approaches the proximity sensor 32 during operation, the feeding rate of the thermal battery stack entering the cylinder will change to the set rate, thus realizing reliable control of the feeding rate of the thermal battery stack entering the cylinder; when the pressure sensor 31 detects that the cylinder entry pressure is the set pressure, the electric cylinder mechanism 2 will stop feeding to avoid pressure overshoot, thus realizing real-time control of the cylinder entry pressure.

[0031] The height pre-adjustment mechanism 5 includes a crank 51, a screw 52, a lead screw slider 53, and an upper pressing block 54. One end of the screw 52 is connected through the crank 51. The other end of the screw 52 is connected to one end of the lead screw slider 53. The other end of the lead screw slider 53 is connected to the upper pressing block 54. When the thermal battery stack enters the cylinder, the operator drives the screw 52 to rotate by rotating the crank 51, and then the lead screw slider 53 adjusts the upper pressing block 54 to a suitable position.

[0032] The screw rod 52 is connected to the support frame 12 through the rotating seat A6, and the screw rod 52 is connected to the lead screw slider 53 through the rotating seat B7. A handle 71 is provided on the rotating seat B7, and the rotating seat B7 can be rotated through the handle 71, thereby finely adjusting the positions of the rotating seat B7, the lead screw slider 53, and the upper pressing block 54.

[0033] A through hole 17 is provided on the workbench surface 15 for the telescopic rod of the servo electric cylinder 21 to pass through the workbench surface 15 and then be threadedly connected to the pressure sensor 31. The diameter of the through hole 17 is smaller than that of the pressure sensor 31 to prevent the pressure sensor 31 from passing through the workbench surface 15.

[0034] The upper pressing block 54 is cylindrical, which is convenient for pushing the thermal battery stack into the thermal battery cylinder body.

[0035] The control device 4 includes a touch screen 41, which is convenient for displaying data and controlling operations. A control system is provided inside the control device 4.

[0036] The usage method of this equipment includes the following steps:

[0037] Preparation:

[0039] Equipment operation:

[0040] Manually press the start button, and the electric cylinder mechanism 2 starts to feed, pushing the battery stack and the thermal battery cylinder body upward. When the battery stack approaches the proximity sensor 32 in the height pre-adjustment mechanism 5, the electric cylinder mechanism 2 feeds at the set rate. When the pressure sensor 31 detects that the pressure for entering the cylinder is greater than or equal to the set pressure, the feeding mechanism stops moving.
