Description

Technical Field

[0001] This utility model belongs to the field of battery testing technology and relates to a pressure plate Z-axis adjustment device. Background Technology

[0002] In the field of large-scale battery product sealing testing, the design of the testing equipment is crucial to ensuring the accuracy and reliability of the tests. Currently, a common testing method is to use multiple chambers for simultaneous testing, with each chamber capable of holding multiple batteries, thereby improving testing efficiency and meeting the needs of large-scale production.

[0003] However, existing testing equipment has significant shortcomings. Previous designs required a contour-following pressure plate to press down and adjust each battery placed in the chamber to prevent bulging. For example, when six batteries were placed in a chamber, six pressure plates were needed. While this design ensured battery stability during testing to some extent, when product models changed, the different shapes and sizes of the batteries necessitated replacing the entire set of pressure plates, significantly increasing changeover time, impacting production efficiency, and raising production costs. Utility Model Content

[0004] The purpose of this invention is to provide a pressure plate Z-axis adjustment device. Through structural improvement, a single pressure plate can simultaneously press down and adjust multiple batteries in the cavity, satisfying the pressing and adjustment operations of different battery models without replacing the pressure plate.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A pressure plate Z-axis adjustment device comprises a Z-axis mechanism and a pressure plate. The Z-axis mechanism includes a base plate fixed on a frame, a lifting platform driven by a motor and screw on the base plate, a vertical channel on the base plate, and a lifting column within the vertical channel. A pressure sensor is installed between the upper end of the lifting column and the lifting platform, and the lower end of the lifting column is connected to the pressure plate. The pressure sensor and the motor are linked by a controller. The controller receives the electrical signal from the pressure sensor and controls the motor according to a preset pressure threshold. When the pressure reaches or exceeds the preset threshold, the controller controls the motor to rotate in the opposite direction, raising the pressure plate upward by a preset height.

[0007] Specifically, when the pressure sensor detects that the pressure plate is in contact with the battery, the motor reverses to lift the pressure plate, leaving a 0.5mm gap between the pressure plate and the surface of the battery.

[0008] As a further improvement of one embodiment of this utility model, a motor carrier plate is provided above the lifting platform. The motor carrier plate and the base plate are fixedly connected by several support columns. A motor is invertedly arranged on the motor carrier plate. The output shaft of the motor is connected to the upper end of a lead screw through a coupling. The lower end of the lead screw is set on the base plate through a bearing seat. A nut that cooperates with the lead screw is provided on the lead screw. The nut is fixedly connected to the lifting platform.

[0009] As a further improvement of one embodiment of the present invention, the middle part of the lifting platform is recessed downward to form a groove for placing nuts.

[0010] As a further improvement of one embodiment of the present invention, the lifting platform is provided with sliding sleeves, the number of which corresponds to the number of support columns, and each support column is vertically inserted into a sliding sleeve.

[0011] As a further improvement of one embodiment of the present invention, the lifting column is provided with vertically distributed sliding grooves, and the lifting platform is provided with a guide block, one end of which is inserted into the sliding groove.

[0012] As a further improvement of one embodiment of the present invention, the lifting column is radially distributed with sealing ring grooves, and a sealing ring is provided in the sealing ring groove. The sealing ring is located in the vertical channel and abuts against the inner wall of the vertical channel.

[0013] As a further improvement of one embodiment of the present invention, the upper end of the lifting column is provided with a slot, a locking block is provided in the slot, the pressure sensor is disposed on the locking block, and the pressure sensor is locked to the lifting platform by bolts.

[0014] As a further improvement of one embodiment of the present invention, the pressure plate is composed of an upper plate and a lower plate, wherein the lower plate is made of plastic and has grooves on its lower end surface.

[0015] The above technical solution has the following advantages: by driving the pressure plate through the linkage of the pressure sensor and the motor, and by pressing the pressure plate down onto the battery and then retracting it, a single pressure plate can simultaneously press down and adjust multiple batteries in the cavity, satisfying the pressing and adjustment operation of different battery models.

Example

[0041] See Figures 1-4 As shown, a pressure plate Z-axis adjustment device includes a Z-axis mechanism and a pressure plate 5. The Z-axis mechanism includes a base plate 1 fixed on the frame. A lifting platform 2 driven by a motor screw is provided on the base plate 1. The motor screw drive structure has the advantages of high transmission accuracy and smooth operation, and can accurately control the lifting action of the lifting platform 2.

[0042] A vertical channel is provided on the substrate 1, and a lifting column 3 is provided within the vertical channel, providing precise guidance for the vertical movement of the lifting column 3. The lifting column 3 not only connects the lifting platform 2 and the pressure plate 5, but also ensures the straightness of the vertical movement under the constraint of the vertical channel, avoiding deviation and ensuring that the pressure plate 5 applies uniform pressure to the battery.

[0043] Pressure sensor 4 is installed between the upper end of the lifting column 3 and the lifting platform 2. It can accurately sense the pressure applied to the battery by the pressure plate 5 in real time and convert the pressure signal into an electrical signal, which is then transmitted to the controller. The controller, acting as the "brain" of the entire device, precisely controls motor 6 based on a preset pressure threshold. When the pressure reaches or exceeds the preset threshold, the controller quickly issues a command to reverse the rotation of motor 6, causing the lifting platform 2 to lift the lifting column 3 and pressure plate 5 upwards to a preset height, for example, leaving a 0.5mm gap between the pressure plate 5 and the battery surface. Motor 6 is a servo motor.

[0044] In practical applications, this method of driving the pressure plate 5 through the linkage of pressure sensor 4 and motor 6 is quite ingenious. The pressure plate 5 is first pressed down to contact the battery, and then the motor 6 reverses to retract it. In this way, one pressure plate 5 can simultaneously press down and adjust multiple batteries in the cavity, and can meet the pressing and adjustment operations of different battery models, greatly improving the versatility and working efficiency of the device and reducing production costs.

[0045] Specifically, to further stabilize the installation position of the motor 6, a motor carrier plate 7 is installed above the lifting platform 2. The motor carrier plate 7 is fixedly connected to the base plate 1 by several support columns 8. The support columns 8 can be distributed at equal intervals to ensure that the motor carrier plate 7 is horizontal and stable.

[0046] A motor 6 is mounted upside down on the motor carrier plate 7. The output shaft of the motor 6 is connected to the upper end of the lead screw 10 via a coupling 9. The coupling 9 can be a flexible coupling or similar type, serving to buffer and compensate for axial misalignment. The lower end of the lead screw 10 is mounted on the base plate 1 via a bearing seat 11, which ensures that the lead screw 10 rotates flexibly and stably. A matching nut 12 is fitted on the lead screw 10, and the nut 12 is fixedly connected to the lifting platform 2. When the motor 6 rotates, it drives the lead screw 10 to rotate via the coupling 9, thereby causing the nut 12 to move up and down along the lead screw 10, ultimately realizing the lifting action of the lifting platform 2.

[0047] Furthermore, to improve the stability and accuracy of the lifting platform 2's operation, sliding sleeves are installed on the lifting platform 2. The number of sliding sleeves matches the number of support columns 8, with a one-to-one correspondence. Each support column 8 is vertically inserted into its corresponding sliding sleeve. The sliding sleeves can be made of wear-resistant, self-lubricating materials, such as copper alloy sleeves, or a structure in which solid lubricant is added inside the metal sleeve can be adopted. The cooperation between the support columns 8 and the sliding sleeves not only guides the lifting of the lifting platform 2, preventing it from deviating, but also reduces frictional resistance during movement, ensuring the long-term stable operation of the device.

[0048] To further explain, the middle of the lifting platform 2 is intentionally recessed downwards, forming a regular groove. The size of this groove is just right for the nut 12 to be securely placed within it. This design ensures a tight connection between the nut 12 and the lifting platform 2, effectively transmitting power to the lifting platform 2 when the lead screw 10 moves the nut 12. Simultaneously, the sliding sleeves are symmetrically distributed on both sides of the groove on the lifting platform 2. This symmetrical layout ensures that the lifting platform 2 experiences even force during lifting, further enhancing its operational stability and reliability, and reducing shaking and jamming.

[0049] In this embodiment, the pressure plate 5 adopts a structure composed of an upper plate 51 and a lower plate 52. The upper plate 51 can be made of metal, such as stainless steel, to ensure the overall structural strength and stability of the pressure plate 5. The lower plate 52 is made of plastic, such as polyethylene, which is relatively soft and can avoid damage to the battery surface. Moreover, the lower end surface of the lower plate 52 is provided with grooves, which can increase the friction with the battery surface, prevent the pressure plate 5 from sliding during the downward adjustment process, and also help reduce the adhesion between the pressure plate 5 and the battery when the pressure plate 5 is lifted.

[0050] In this embodiment, to further optimize the cooperation structure between the lifting column 3 and the lifting platform 2 and ensure the stability and reliability of the lifting process, vertically distributed grooves 31 are provided on the lifting column 3. These grooves 31 extend along the axial direction of the lifting column 3, ensuring a good guiding effect. Correspondingly, a guide block 13 is provided on the lifting platform 2. The shape of the guide block 13 is adapted to the groove 31, with one end precisely inserted into the groove 31. When the lifting column 3 moves up and down, the guide block 13 slides within the groove 31, effectively preventing the lifting column 3 from deviating and ensuring the accuracy of its vertical lifting. The guide block 13 can also be made of a wear-resistant material, such as polyoxymethylene, to reduce wear between it and the groove 31 and extend its service life.

[0051] Meanwhile, considering the sealing performance of the vertical channel and preventing dust, impurities, etc., from entering the channel and affecting the operation of the device, sealing ring grooves are radially distributed on the lifting column 3. The dimensions of the sealing ring grooves are designed according to the specifications of the sealing ring 14, which is made of rubber material with good elasticity and sealing performance, such as nitrile rubber. The sealing ring 14 is installed in the sealing ring groove and located within the vertical channel, tightly abutting against the inner wall of the vertical channel to form a reliable sealing structure, effectively preventing external substances from entering.

[0052] Furthermore, to facilitate the installation and fixation of the pressure sensor 4, a slot is provided at the upper end of the lifting column 3. The shape and size of the slot match the locking block 15, allowing the locking block 15 to be securely embedded within the slot. The pressure sensor 4 is mounted on the locking block 15 and secured to the lifting platform 2 with bolts. This installation method not only facilitates the disassembly and replacement of the pressure sensor 4 but also ensures a secure connection between it and the lifting column 3 and the lifting platform 2, accurately transmitting pressure signals.

[0053] This utility model provides a pressure plate Z-axis adjustment device, which is a component of a battery product sealing test equipment. This pressure plate Z-axis adjustment device works closely with other parts of the battery product sealing test equipment, sharing the control system, power supply system, etc. of the battery product sealing test equipment. Through a unified interface and operation instructions, the coordinated operation of each link is realized to achieve the sealing test of the battery product.

[0054] The innovative design of this utility model lies in the ingenious integration of the pressure plate into the Z-axis mechanism, which is composed of components such as the lifting platform 2 and the lifting column 3 to form a stable structure. During operation, the pressure sensor 4 plays a crucial role in linkage. When the pressure plate 5 is pressed down by the Z-axis mechanism and comes into contact with the battery, the pressure sensor 4 senses the pressure change in real time. Once the pressure reaches a preset threshold, it quickly feeds back a signal, driving the Z-axis mechanism to retract the pressure plate 5. Through this unique method of pressing down and then retracting, a single pressure plate 5 can accurately and synchronously adjust the pressure of multiple batteries in the cavity. Moreover, this design has excellent versatility. For different battery models, only the preset threshold of the pressure sensor 4 and the motion parameters of the Z-axis mechanism need to be adjusted to easily meet diverse pressure adjustment needs, greatly improving battery handling efficiency and the practicality of the device.
