Description

Technical Field

[0001] This utility model relates to the field of battery cover shaping fixtures, and in particular to a cooling and shaping fixture for battery covers made of thermosetting polymer composite materials. Background Technology

[0002] The battery cover is a thermosetting polymer composite injection molded part. After injection molding, it is still hot when removed from the mold. If the battery cover is cooled naturally, it will warp and deform, becoming a defective part. To prevent deformation during the cooling process, the battery cover, freshly removed from the mold, is usually placed on a cooling and shaping fixture for rapid cooling and shape retention.

[0003] Patent CN208946666U discloses a battery box cover cooling and shaping fixture, including components such as a base plate, a seat plate, a pressure frame, a support frame, a rotary cylinder, a limiting post, and a fan. In use, the rotary cylinder first rotates outward to remove the lower pressure frame. Then, the freshly injection-molded battery box cover is removed from the mold and placed on the support frame. Next, the pressure frame is installed, pressing against the edge of the battery box cover. The rotary cylinder then rotates, causing the pressure block to press against the pressure frame. A cooling fan on the seat plate blows cold air to cool the battery box cover. After a certain cooling time, the rotary cylinder rotates again to remove the pressure frame, and then the battery box cover is removed. The disadvantages of existing battery box cover cooling and shaping fixtures are poor positioning and support for the battery cover, low positioning accuracy, and cumbersome operation. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor positioning and support effect, poor positioning accuracy, and cumbersome operation of existing battery box cover cooling and shaping fixtures, and to provide a battery cover cooling and shaping fixture made of thermosetting polymer composite material.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cooling and shaping fixture for a battery cover made of thermosetting polymer composite material includes a support, a worktable, a heat dissipation assembly, an inner positioning component, an inner support component, and an outer edge positioning component. The worktable is mounted on the support and has several heat dissipation vents. The heat dissipation assembly includes a cooling fan and heat dissipation pipes. The cooling fan is positioned below the heat dissipation vents. The inner positioning component of the cooling fan outlet includes multiple positioning plates. When the positioning plates are positioned along the inner sidewall of the battery cover, they are vertically arranged. The inner support component includes several groups. Each group of inner support components includes a support column and a support plate. The support plate has suction cups for fixing the inner wall of the top plate of the battery cover. There are multiple groups of outer edge positioning components. When the outer edge positioning components are positioned along the outer edge of the battery cover, they are arranged at the outer edge position.

[0007] In the above solution, the outer edge positioning component includes a pad, a clamping cylinder, and a pressing block. The pad is fixedly connected to the worktable and is used to support the edge of the battery cover that needs to be cooled and shaped. The clamping cylinder is set on the worktable and located outside the pad. A pressing arm is provided on the upper part of the clamping cylinder, and the pressing block is fixedly connected to the lower end of the pressing arm. The position of the pressing block corresponds to the position of the pad. With this arrangement, the pad can support the outer edge of the battery cover, and the clamping cylinder drives the pressing block to rotate and move up and down, thereby clamping and fixing the outer edge of the battery cover. This ensures that the outer edge of the battery cover remains horizontal during the cooling process, and that the outer edge is flat after the battery cover has cooled and shaped.

[0008] In the above design, the workbench is equipped with three heat dissipation vents spaced at intervals, and a cooling fan is installed below each of the three vents. This arrangement improves the heat dissipation efficiency of the battery cover.

[0009] In the above design, there are four sets of internal support components, each positioned above a heat dissipation vent. The lower end of the support column is fixedly connected to the worktable via an adjustable clamping device. Multiple ventilation holes are distributed on the support plate, and two suction cups are spaced at intervals on the support plate. This configuration allows for adjustment of the support plate's height, ensuring stable support and fixation of the battery cover's top plate. The suction cups also help maintain the battery cover's flatness during cooling, preventing deformation.

[0010] In the above solution, a position sensor is provided on the inner support component. By setting the position sensor, the placement position of the battery cover can be detected, improving the positioning accuracy of the battery cover. The number and placement of the position sensors can be selected as needed. Preferably, two position sensors can be set: one position sensor is located in the center of the worktable, and the other position sensor is located at a position corresponding to the corner of the battery cover. The cooperation of the two position sensors can improve the positioning accuracy of the battery cover on the battery cover cooling and shaping fixture.

[0011] In the above solution, an alarm is installed at the edge of the workbench. By setting the alarm, it can be triggered when an abnormality occurs, ensuring safe operation.

[0012] In the above design, the bottom of the bracket is equipped with rollers, which are located at the four corners of the bottom of the bracket. The rollers facilitate the movement of the battery cover cooling and shaping fixture.

[0013] In the above design, the bottom of the bracket is provided with a fork tooth positioning groove, which is located in the middle of the bottom of the bracket. By providing the fork tooth positioning groove, the battery cover cooling and shaping fixture can be moved by a forklift.

[0014] This invention offers several advantages: The thermosetting polymer composite battery cover cooling and shaping fixture utilizes an inner positioning component to position the four side panels of the battery cover, an inner support component to support and position the top panel, and an outer edge positioning component to press and position the outer edge. Through the combined action of these components, comprehensive positioning of all surfaces of the battery cover is achieved, enabling high-precision shaping of the freshly injection-molded battery cover to meet design requirements. Simultaneously, it ensures structural stability and prevents deformation during cooling. Furthermore, the invention incorporates a heat dissipation component for ventilation and cooling of the battery cover, and heat dissipation pipes to transport hot air drawn in by the cooling fan to a distance, thereby improving the heat dissipation efficiency of the battery cover.

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below through embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0020] like Figure 1-3 As shown, the battery cover cooling and shaping fixture of the thermosetting polymer composite material of this utility model includes a bracket 1, a worktable 2, a heat dissipation component 3, an inner positioning component 4, an inner support component 5, and an outer edge positioning component 6.

[0021] Support 1 is a support that is fixedly connected by profiles, and the top of the support is fixedly connected to the workbench.

[0022] Workbench 2 is a flat workbench supported by a certain strength plate. Several heat dissipation vents 21 are provided on workbench 2. The heat dissipation vents 21 can be arranged in a manner that can be selected as needed, for example, according to the attached... Figure 1 As shown, four large heat dissipation vents 21 are set on the worktable. For safety, a protective net can be installed at each heat dissipation vent. When the battery cover is positioned on the battery cover cooling and shaping fixture, the heat dissipation vents are located on the inside of the battery cover.

[0023] A mounting bracket for assembling the heat dissipation assembly 3 is provided below the workbench 2. The heat dissipation assembly 3 includes a cooling fan 31 and a heat dissipation pipe 32. Both the cooling fan 31 and the heat dissipation pipe 32 are fixedly mounted on the mounting bracket below the workbench. The cooling fan 31 is an exhaust fan used to draw hot air around the battery cover 9 into the heat dissipation pipe, and then transport it to a distant location through the heat dissipation pipe 32. The heat dissipation pipe 32 is hermetically connected to the air outlet of the cooling fan 31. The number of cooling fans 31 is the same as the number of heat dissipation vents 21. A cooling fan 31 is correspondingly set below each heat dissipation vent 21. This arrangement allows the cooling fans to draw air from above the heat dissipation vent, causing the air around the battery cover to flow into the battery cover, carrying away the heat from the battery cover and improving the cooling efficiency of the battery cover.

[0024] An inner positioning component 4 is provided on the workbench 2. The inner positioning component 4 includes multiple positioning plates. When the positioning plates are positioned on the battery cover cooling and shaping fixture along the battery cover 9, their inner sidewalls are vertically set. The spacing and number of positioning plates can be selected as needed. The material of the positioning plates is preferably a high-strength material that is not easily deformed.

[0025] An inner support component 5 is provided on the workbench 2. The inner support component 5 consists of several groups, and the number of inner support components 5 can be selected as needed, for example, according to the attached... Figure 1 As shown, four sets of internal support components are set on the workbench, and the position of each set of internal support components corresponds to the position of the heat dissipation vent.

[0026] Each set of internal support components 5 includes a support column 51 and a support plate 52. The support plate 52 is provided with a suction cup 53 for fixing the inner wall of the top plate of the battery cover. The suction cup can be a pneumatic suction cup, which is used to adsorb and fix the top plate of the battery cover by an air pump during operation.

[0027] The lower end of the support column 51 is fixedly connected to the worktable 2 via an adjustable clamping member 54. This configuration allows for adjustment of the height of the support plate 52, enabling it to provide stable support for the top plate of the battery cover 9. Multiple ventilation holes 55 are distributed on the support plate 52, allowing for better ventilation and heat dissipation on the top plate of the battery cover 9. Two suction cups 53 are spaced apart on the support plate 52, further stabilizing the connection between the support plate 52 and the top plate of the battery cover 9. The suction cups ensure the battery cover remains flat during cooling, preventing deformation.

[0028] The workbench 2 is provided with an outer edge positioning component 6. There are multiple sets of outer edge positioning components 6. When the outer edge positioning component 6 is positioned along the battery cover 9 on the battery cover cooling and shaping fixture, its outer edge position is set.

[0029] Each set of outer edge positioning components 6 includes a pad 61, a clamping cylinder 62, and a pressing block 63. The pad 61 is fixedly connected to the worktable 2 and is used to support the edge of the battery cover 9 that needs to be cooled and shaped. The clamping cylinder 62 is set on the worktable 2 and is located outside the pad 61. A pressing arm is provided on the upper part of the clamping cylinder 62, and the pressing block 63 is fixedly connected to the lower end of the pressing arm. The position of the pressing block 63 corresponds to the position of the pad 61. With this arrangement, the pad 61 can support the outer edge of the battery cover 9, and the clamping cylinder 62 drives the pressing block 63 to rotate and move up and down to achieve the clamping and fixing of the outer edge of the battery cover 9, so that the outer edge of the battery cover 9 remains horizontal during the cooling process, and the outer edge of the battery cover is flat after cooling and shaping.

[0030] A position sensor 7 is provided on the inner support 5. By setting the position sensor 7, the placement position of the battery cover 9 can be detected, thereby improving the positioning accuracy of the battery cover 9. The number and placement position of the position sensors 9 can be selected as needed. Preferably, two position sensors can be set, one position sensor is set in the middle of the worktable, and the other position sensor is set at a position corresponding to the corner of the battery cover. Through the cooperation of the two position sensors, the positioning accuracy of the battery cover 9 on the battery cover cooling and shaping fixture can be improved.

[0031] An alarm 8 is installed on the edge of the workbench 2. By setting the alarm 8, the alarm can be triggered when an abnormality occurs, ensuring safe operation.

[0032] Rollers 11 are provided at the bottom of the bracket 1, and the rollers 11 are located at the four corners of the bottom of the bracket 1. By providing rollers 11, it is convenient to move the battery cover cooling and shaping fixture.

[0033] A fork tooth positioning groove 12 is provided at the bottom of the bracket 1, and the fork tooth positioning groove 12 is located at the middle of the bottom of the bracket 1. By providing the fork tooth positioning groove, the battery cover cooling and shaping fixture can be moved by a forklift.

[0034] This utility model relates to a thermosetting polymer composite battery cover cooling and shaping fixture. In use, the outer edge positioning component is first rotated to the outward position. Then, the injection-molded battery cover is placed on the worktable with the opening facing downwards. Simultaneously, the positioning holes on the battery cover align with the probes on the position sensor for positioning. The top plate of the battery cover is then fixedly connected to the suction cup on the inner support component. The suction cup can be a pneumatic suction cup. After the suction cup adsorbs the battery cover, the four sides of the battery cover contact and are positioned with the inner positioning plate on the worktable. The outer edge of the battery cover corresponds to the pad on the outer edge positioning component on the worktable. Using a control button, the clamping cylinder is rotated to the inward position, causing the clamping cylinder to lower the pressure block, which presses against the outer edge of the battery cover. The combination of the pressure block and the pad secures and positions the outer edge of the battery cover. This operation completes the shaping and positioning of the battery cover. Then, the cooling fan is activated to draw air from inside the battery cover, allowing cool outside air to flow over it and cool the cover. Meanwhile, hot air carrying heat is transported away through cooling pipes, ensuring rapid cooling of the battery cover. Once the battery cover has cooled and set, the cooling fan is turned off, the clamping cylinder is raised and rotated to the outer position, and the air pump is used to release the suction cups. The cooled and set battery cover can then be removed manually or mechanically. Repeating this process allows for the reshaping, positioning, and cooling of the battery cover removed from the injection mold.

[0035] This utility model relates to a thermosetting polymer composite battery cover cooling and shaping fixture. It utilizes an inner positioning component to position the four side panels of the battery cover, an inner support component to support and position the top panel, and an outer edge positioning component to press and position the outer edge of the battery cover. The combined action of these components ensures comprehensive positioning of all surfaces of the battery cover, guaranteeing structural stability and preventing deformation during cooling. A position sensor detects the battery cover's position on the fixture, improving positioning accuracy. Suction cups on the inner support component provide both support and positioning, further stabilizing the battery cover and preventing deformation during cooling. An alarm prevents accidental entry of personnel or objects into the fixture area, thus protecting the battery cover during the cooling and shaping process. By incorporating heat dissipation components, the battery cover can be ventilated and cooled. Heat dissipation pipes allow hot air drawn in by the cooling fan to be transported to a distance, improving the heat dissipation efficiency of the battery cover. Rollers on the support frame facilitate the movement of the battery cover cooling and shaping fixture, and forklift positioning slots allow for the handling of the fixture.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
