Description

Technical Field

[0001] This utility model relates to the field of battery processing equipment, specifically to a heat-pressed filter plate device. Background Technology

[0002] Battery covers are typically used to seal the top of the battery, protecting the internal battery components, preventing foreign objects from entering, and preventing internal solutions from overflowing when tilted. Before installing the battery cover, a vent filter needs to be installed in the corresponding vent position on the battery cover. The vent filter is mainly for gas venting. The size and number of vents should ensure that gases generated inside the battery can be discharged in a timely manner during charging and discharging, preventing excessive internal pressure and safety issues. The appropriate total area of ​​the vents is determined based on the battery capacity and the expected amount of gas generated. Larger capacity batteries may require more or larger vents.

[0003] Existing equipment for installing air filters mainly involves manually pulling a pressure rod, with the bottom of the rod moving downwards to press the air filter placed on the battery case cover into the exhaust port. However, the existing installation equipment lacks a structure for positioning the battery case cover. Usually, installers align and press the filter by marking the base or by pressing the pressure rod down to a certain distance. This installation method is not conducive to improving installation efficiency and has a high defect rate. Utility Model Content

[0004] The heat-pressed air filter device of this invention can effectively solve the problems of low installation efficiency and high defect rate of the air filter installation equipment in the prior art.

[0005] According to one aspect of the present invention, a heat-pressing filter sheet device is provided for installing a filter sheet to a housing cover, comprising:

[0006] The base is equipped with a movable pressure plate; the base is also equipped with a first positioning plate and a second positioning plate;

[0007] A drive device is mounted on the base; the output end of the drive device is connected to the pressure plate.

[0008] The heating head is mounted on the pressure plate;

[0009] The adjacent sides of the shell cover abut against the first positioning plate and the second positioning plate respectively to define the position of the shell cover. The pressure plate is driven to move by the driving device to drive the heating head to press down, so that the heating head presses the air filter into the shell cover.

[0010] In some embodiments, the second positioning plate is movably disposed on the base. Both the first and second positioning plates have abutment surfaces that contact the cover, and the abutment surfaces of the first and second positioning plates are perpendicular to each other. Thus, the abutment surfaces can be curved or flat, adaptable to the contact surface of the cover, and the perpendicularity of the abutment surfaces facilitates quick abutment positioning and adjustment of the cover's position.

[0011] In some embodiments, the cover has positioning holes on both sides, and a positioning post is provided on the abutment surface of the first positioning plate. When the cover moves along the second positioning plate and abuts against the abutment surface of the first positioning plate, the positioning hole inserts into the positioning post. Thus, the cooperation between the positioning post and the positioning hole can further improve the positioning accuracy and adjustment efficiency of the cover.

[0012] In some embodiments, the base is provided with a first slide rail, and the pressure plate is provided with a first slide block. The first slide block is slidably mounted on the first slide rail, allowing the pressure plate to move along the first slide rail. Thus, the pressure plate, through the sliding engagement of the first slide block and the first slide rail, can improve the accuracy of the pressing head when it presses down.

[0013] In some embodiments, the pressure plate is provided with a second slide rail, and the second slide rail is provided with a second slide base that is slidably connected to it. The heating head is disposed on the second slide base so as to drive the heating head to move along the second slide rail. Thus, the heating head can move along the second slide rail to adjust to the desired position and can accommodate multiple models of housings.

[0014] In some embodiments, the second slide is provided with an adjusting handle. The adjusting handle has a contact end extending into the interior of the second slide. When force is applied to the adjusting handle, the contact end moves, causing it to abut against the second slide rail, thereby locking the heating head on the second slide rail. Thus, by applying force to the adjusting handle, the second slide can be locked, thereby locking the position of the heating head. The heating head can continuously move in a fixed position when pressed down, and is not easily deviated from its position.

[0015] In some embodiments, a limiting member is provided inside the second slide block. The limiting member is throttle-connected to the adjusting handle. When the adjusting handle is subjected to force, it drives the limiting member to abut against the second slide rail, thereby locking the heating head on the second slide rail. Thus, by locking the position of the heating head through the abutting cooperation between the limiting member and the second slide rail, damage to the adjusting handle can be avoided, which helps to improve the strength of locking the heating head.

[0016] In some embodiments, the base is provided with a positioning rod that passes through the pressure plate, and the driving device drives the pressure plate to move along the positioning rod. Thus, by limiting the movement trajectory of the pressure plate by the positioning rod, the pressing accuracy of the pressure plate can be further improved.

[0017] In some embodiments, the heating head has a pressure head and an elastic element, the elastic element abutting against the pressure head, the driving device driving the pressure head, and the pressure head pressing the air filter through the elastic element.

[0018] In some embodiments, the heating head is provided with a connection hole, which is electrically connected to an external heating system via a wire, and the bottom end of the heating head is provided with a heating hole.

[0019] Compared with the prior art, the heat-pressing filter device of this utility model has the following advantages:

[0020] This application uses a drive device as power to save the operator's physical strength in pressing and installing the air filter. The base is provided with a first positioning plate and a second positioning plate. The adjacent sides of the cover can abut against the first positioning plate and the second positioning plate to limit the position of the cover. Therefore, the cover can be quickly positioned in the preset position. Then, the drive device drives the pressing head to press down and install the air filter. The entire installation process is more accurate and less prone to deviation, effectively improving the efficiency of installing the air filter. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] like Figure 1 As shown, this utility model relates to a heat-pressing filter sheet device for installing a filter sheet (not shown) onto a housing cover. The filter sheet is breathable and has a thin sheet structure. Specifically, the housing cover is a battery housing cover 4, which has vent holes 41. The filter sheet can be installed in the vent holes 41. The diameter of the vent holes 41 is smaller than the diameter of the filter sheet, so that the filter sheet is centered and covers the vent hole 41. The following embodiment uses two vent holes 41 on the battery housing cover 4 as an example. The battery housing cover 4 is preferably a rectangular cover structure with four flat sides. Of course, it is not limited to the battery housing cover 4; other housing covers that require the installation of a filter sheet are also applicable.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] Figure 1 The diagram schematically illustrates a heat-pressing filter sheet device according to one embodiment of the present invention. For example... Figure 2 As shown, the side pointing in the direction of gravity is the lower side, and the opposite side is the upper side. The heat-pressing filter device includes a base 1, a driving device 2, and a heat-pressing head 3.

[0035] like Figure 2 , Figure 3 As shown, the base 1 adopts a frame structure to support the drive device 2. The bottom (base plate) of the base 1 preferably adopts a flat plate structure so that the battery cover 4 can fit snugly on the base plate of the base 1. The base 1 is provided with a pressure plate 11 that can move in the vertical direction. The pressure plate 11 adopts a rectangular flat plate structure and is movably set on the upper side of the base plate. The base 1 is provided with positioning rods 12. The number of positioning rods 12 is preferably four and they are evenly distributed at the four corners of the base 1. The positioning rods 12 pass through the four right-angle corners of the pressure plate 11 through the through holes of the pressure plate 11, so that the pressure plate 11 can move along the positioning rods 12. That is, the moving direction of the pressure plate 11 is limited by the positioning rods 12, and the pressing accuracy of the pressure plate 11 is higher. The side wall of the base 1 is provided with a first slide rail 15. The first slide rail 15 is located on the rear side wall of the base 1 (the side away from the operator during use). The number of first slide rails 15 is preferably two and they are symmetrically arranged on the base 1. The first slide rail 15 adopts a smooth convex strip structure and extends in the vertical direction. The pressure plate 11 has a first slide block 111 on the side near the first slide rail 15. The number and position of the first slide blocks 111 are adapted to the first slide rail 15. The first slide block 111 adopts a block structure and has a groove structure that can slide and cooperate with the first slide rail 15. That is, the first slide block 111 is movably set on the first slide rail 15 to drive the pressure plate 11 to move along the first slide rail 15, so that the pressure plate 11 moves more smoothly and has higher balance and accuracy.

[0036] Furthermore, such as Figure 4 As shown, a second slide rail 112 is provided on the lower side (bottom surface) of the pressure plate 11. The second slide rail 112 adopts a smooth convex strip structure with a trapezoidal cross-section, exhibiting a shape that is narrower at the top and wider at the bottom. The second slide rail 112 extends along the left-right direction (orthogonal to the direction of gravity). A second slide seat 113 is provided on the second slide rail 112 for sliding engagement with it. Preferably, there are two second slide seats 113. The second slide seats 113 have a groove structure that adapts to the second slide rail 112. The second slide seats 113 can move smoothly at the bottom of the pressure plate 11 by sliding engagement with the second slide rail 112. The heating head 3 is located at the bottom of the second slide seat 113, that is, the position of the heating head 3 can be adjusted by moving the second slide seat 113. The heating head 3 is used to install the filter sheet. Figure 5As shown, the second slide 113 is provided with an adjusting handle 114. The adjusting handle 114 is located on the front side of the second slide 113 (the side closer to the operator). The adjusting handle 114 is used for manual control by the operator. One end of the adjusting handle 114 extending into the inner side of the second slide 113 is a contact end 115. The part of the adjusting handle 114 extending into the second slide 113 is provided with an external thread structure. The second slide 113 is provided with a threaded hole that is threaded to engage with the adjusting handle 114. After the adjusting handle 114 is turned, the thread engagement causes the contact end 115 to abut against the second slide rail 112, so as to lock the second slide 113 onto the second slide rail 112. Therefore, the position of the pressing head 3 can also be locked, thereby facilitating the adjustment of the pressing position of the pressing head 3.

[0037] In some embodiments, such as Figure 6 As shown, a limiting member 116 is provided inside the second slide block 113. The limiting member 116 can be a sheet structure that adapts to the side profile of the second slide rail 112. A groove structure or cavity structure that allows the limiting member 116 to move can be provided inside the second slide block 113. Similarly, a threaded hole or through hole is provided on the second slide block 113. The external thread structure of the adjusting handle 114 can be rotatably set in the threaded hole or through hole, and the adjusting handle 114 is threadedly connected to the limiting member 116, so that when the adjusting handle 114 rotates, it can drive the limiting member 116 to move along the front and rear directions. The limiting member 116 moves closer to or further away from the second slide rail 112. When the limiting member 116 abuts against the second slide rail 112, the second slide block 113 and the heating head 3 are locked on the second slide rail 112. The position of the heating head 3 can also be quickly adjusted. The structure of this embodiment can prevent the adjusting handle 114 from contacting the second slide rail 112. The limiting member 116 can be made of a soft and wear-resistant material to prevent damage to the second slide rail 112. Therefore, it can effectively protect the second slide rail 112 and the adjusting handle 114, which is beneficial to improving the service life and locking strength.

[0038] Furthermore, such as Figure 2As shown, the base plate of the base 1 is also provided with a first positioning plate 13 and a second positioning plate 14. The first positioning plate 13 is fixedly installed on the left side of the base plate of the base 1. The first positioning plate 13 can also adopt a convex strip structure and can extend along the front-back direction. The second positioning plate 14 adopts a plate structure and extends along the left-right direction. The second positioning plate 14 is movably and adjustablely installed on the base plate of the base 1. The second positioning plate 14 can extend along the front-back direction and has two oblong holes. The oblong holes have an adjustable size in the front-back direction. The base plate of the base 1 can be provided with threaded holes at the positions corresponding to the oblong holes. The second positioning plate 14 can be locked in the required position on the base 1 by screws or bolts, so that the second positioning plate 14 can be adjusted to move a certain distance in the front-back direction. Both the first positioning plate 13 and the second positioning plate 14 have abutment surfaces 1a. Preferably, the abutment surfaces 1a are planar structures with high flatness. When the battery cover 4 is placed on the base plate 1, two adjacent sides of the battery cover 4 can abut against the abutment surfaces 1a of the first positioning plate 13 and the second positioning plate 14, respectively, to define the position of the battery cover 4. Preferably, the abutment surfaces 1a of the first positioning plate 13 and the second positioning plate 14 are perpendicular to each other, so that the second positioning plate 14 can be adjusted more precisely. When adjacent sides of the battery cover 4 abut against the first positioning plate 13 and the second positioning plate 14, the position of the battery cover 4 on the base plate 1 is defined, which facilitates rapid positioning of the battery cover 4.

[0039] In some embodiments, such as Figure 7 As shown, the first positioning plate 13 is provided with a positioning post 131, which is a cylindrical structure protruding to the right. The left and right sides of the battery cover 4 are provided with positioning holes 42, the diameter of which is adapted to the diameter of the positioning post 131. The battery cover 4 can drive the positioning hole 42 to be inserted into the positioning post 131, thereby further improving the positioning accuracy of the battery cover 4. At the same time, the second positioning plate 14 can be easily adjusted to quickly adapt to different models of battery cover 4. In use, the battery cover 4 abuts against the second positioning plate 14 and moves along the second positioning plate 14 until it abuts against the first positioning plate 13, so that the positioning post 131 is inserted into the positioning hole 42, which effectively improves the positioning accuracy and positioning efficiency of the battery cover 4.

[0040] The drive device 2 provides the power for the downward movement of the pressure plate 11. The drive device 2 is preferably a telescopic cylinder, but other telescopic motors are also suitable. The drive device 2 is controlled by a solenoid valve (not shown) to perform the telescopic action. The drive device 2 can be fixedly mounted on the top of the base 1. The output end of the drive device 2 extends into the base 1 and connects to the pressure plate 11, meaning the drive device 2 can drive the pressure plate 11 to perform the telescopic action. Preferably, the output end of the drive device 2 is positioned in the middle of the four positioning rods 12, resulting in better balance when the pressure plate 11 moves.

[0041] The heating head 3 moves downwards via the pressure plate 11 to install the air filter. Different types of heating heads 3 can be selected depending on the installation procedure and the performance of the battery. In this embodiment, for example... Figure 4 , Figure 8 As shown, two different types of heating heads 3 are provided. The first type is a direct-pressure heating head 3. This type of heating head 3 can press the filter sheet into the exhaust hole 41. The heating head 3 has a pressure head 31 and an elastic element 32. The heating head 3 extends downward into a shaft-shaped structure. The pressure head 31 is located at the bottom of the shaft-shaped structure. The pressure head 31 can be cylindrical. The pressure head 31 has a certain extension and retraction distance on the heating head 3 and is reset by the elastic element 32. The elastic element 32 is preferably a spring. The elastic element 32 is sleeved on the shaft-shaped structure of the heating head 3 and abuts against the pressure head 31. When the heating head 3 presses down, it drives the pressure head 31 to press the filter sheet. The elastic element 32 enables the pressure head 31 to have a certain buffering performance and can also correct misalignment during the placement of the filter sheet to further improve the accuracy of pressing the filter sheet. The second type is a hot-press type heating head 3, which requires an external heating system (not shown) for control. This type of heating head 3 has a connecting hole 33 on its side, which is electrically connected to the external heating system through a wire. The heating head 3 is also equipped with a heating device (not shown) so that the end of the heating head 3 is heated. Therefore, the heating head 3 needs to have good thermal conductivity. The heating head 3 has a downward-extending shaft structure, and a heating hole 34 is provided at the bottom of the shaft structure. The heating hole 34 is recessed by 4mm in the shaft structure, with an inner diameter of 15mm and an outer diameter of 18mm (values ​​are for reference only). This type of heating head 3 can press down on the edge plastic of the exhaust hole 41 so that its edge covers the edge of the filter plate to achieve heating and fixation.

[0042] In other embodiments, the two types of heating heads 3 can also be combined into a single structure to implement two functions. The heating heads 3 can be switched in the corresponding battery cover 4, or a heating device can be added to the position of the heating head 31 so that heating can be turned off when not in use, while retaining the performance of the elastic element 32.

[0043] When using the device, the position of the battery cover 4 needs to be preset first. Place the battery cover 4 on the base plate of the base 1 and bring it close to and abut against the first positioning plate 13. Alternatively, the positioning pin 131 can be used in conjunction with the positioning hole 42 for quick positioning. Then, move the second positioning plate 14 close to the battery cover 4 until it abuts against the battery cover 4. When the adjacent sides of the battery cover 4 abut against the first positioning plate 13 and the second positioning plate 14 respectively, control the pressure plate 11 to press down and move so that the heating head 3 is close to the position of the exhaust hole 41. Then, move the second slide 113 to move the heating head 3 to the position corresponding to the exhaust hole 41. The position of the second positioning plate 14 in the front and back directions can be adjusted appropriately. When the heating head 3 can be completely aligned with the exhaust hole 41, lock the second positioning plate 14 to complete the position setting of the current model of the battery cover 4. When installing the air filter, the battery cover 4 can first abut against the second positioning plate 14, then move along the second positioning plate 14 to approach and abut against the first positioning plate 13, and press the heating head 3 under the control drive device 2 to achieve quick and accurate installation of the air filter.

[0044] The above description is merely a preferred embodiment of the present utility model. To simplify the description, not all possible combinations of the various technical features in the above embodiments have been described, and this is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
