Description

Technical Field

[0001] This utility model relates to the field of battery module installation technology, and more specifically, to a module workpiece fixing device. Background Technology

[0002] During battery module installation, the module components need to be fixed in place. Adhesive is then applied to the cell slots within the module components, and the cells are installed inside the slots. Once the adhesive cures, the cells are bonded and fixed to the module components. Current methods for fixing module components typically involve using locating pins on a tooling fixture to engage with locating holes in the module components for positioning and fixation.

[0003] However, due to the short protrusion of the locating pin, the workpiece is not well fixed. During the transfer process, the tooling is easily impacted, causing the workpiece to pop out of the locating pin. The gluing equipment cannot accurately identify the position of the workpiece, affecting production. In addition, the glue nozzle may collide with the workpiece during glue application, easily hooking the workpiece and causing glue application failure, which also affects production.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] As described in the background section, existing methods for fixing modular workpieces typically involve setting locating pins on the tooling fixture, which engage with locating holes in the modular workpiece to achieve positioning and fixation. However, due to the short protruding portion of the locating pin, the workpiece fixing effect is poor. During transport, the tooling fixture is easily impacted, causing the workpiece to pop out of the locating pin. The gluing equipment cannot accurately identify the workpiece position, affecting production. Furthermore, the glue nozzle may collide with the workpiece during glue application, easily hooking the workpiece and causing glue application failure, which also affects production.

[0038] Based on this, please refer to Figures 1-6 This utility model provides a module workpiece fixing device 100, which can effectively improve the aforementioned technical problems. Specifically, it improves the fixing effect of the module workpiece 200, avoids shaking during transport and gluing, ensures normal gluing of the gluing equipment and normal production of battery modules, thereby improving production efficiency. The module workpiece fixing device 100 will be described in detail below.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the module workpiece fixing device 100 provided in this embodiment. Figure 2 This is a schematic diagram of the installation of the module workpiece fixing device 100 and the module workpiece 200 provided in this embodiment, combined with... Figure 1 and Figure 2 The module workpiece fixing device 100 includes a tooling base plate 10 and at least two workpiece fixing components 20. The tooling base plate 10 has an installation groove 11 for mounting the module workpiece 200. The at least two workpiece fixing components 20 are spaced apart on the tooling base plate 10 and are used to press the top of the module workpiece 200 to fix the module workpiece 200 in the installation groove 11.

[0040] As is easily understood, by placing the module workpiece 200 in the mounting groove 11 of the tooling base plate 10, the module workpiece 200 can be limited in the left-right or front-back directions. Then, by pressing the top of the module workpiece 200 with the workpiece fixing component 20, the module workpiece 200 can be limited in the up-down direction. In other words, by utilizing the coordinated cooperation between the workpiece fixing component 20 and the tooling base plate 10, the module workpiece 200 is fixed in different directions, improving its stability during subsequent transportation or gluing processes, avoiding shaking during production operations, thereby ensuring normal gluing of the gluing equipment, normal production of battery modules, and improving production efficiency.

[0041] It should be noted that in this embodiment, there are two workpiece fixing components 20, which are located on opposite sides of the mounting groove 11. That is, the two workpiece fixing components 20 can clamp and fix the opposite ends of the module workpiece 200. Of course, in other embodiments, the number of workpiece fixing components 20 can be three, four, or five, etc. The specific number and the clamping position on the module workpiece 200 need to be determined according to the actual design requirements.

[0042] For details, please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the workpiece fixing assembly 20 provided in this embodiment. Figure 4 This is an exploded view of the workpiece fixing assembly 20 provided in this embodiment, combined with... Figures 1-4 The workpiece fixing assembly 20 includes a fixing block 21, a locking member 22, and a fixing pressure block 23. The fixing block 21 is disposed on the tooling base plate 10, the locking member 22 is disposed on the fixing block 21, and the fixing pressure block 23 is rotatably connected to the locking member 22 and is located on the side of the fixing block 21 away from the tooling base plate 10. The locking member 22 is used to fasten the fixing pressure block 23 to the fixing block 21, so that the fixing pressure block 23 presses against the top of the module workpiece 200.

[0043] Understandably, by rotating the fixed pressure block 23 relative to the locking member 22, the module workpiece 200 can be pressed or released. Specifically, before the glue application operation, the module workpiece 200 is placed in the mounting slot 11, and then the fixed pressure block 23 is rotated so that it is positioned above the module workpiece 200; then the locking member 22 is operated to fasten the fixed pressure block 23 to the fixed stop block 21, that is, to move the fixed pressure block 23 toward the module workpiece 200, thereby pressing the top of the module workpiece 200 to achieve pressing and fixing. After the module workpiece 200 is glued, the locking member 22 is operated to release the locking effect on the fixed pressure block 23, and then the fixed pressure block 23 is rotated again to release the pressing effect on the module workpiece 200. Finally, the module workpiece 200 can be removed from the mounting slot 11 of the tooling base plate 10. The whole operation process is convenient and quick, which can improve production efficiency.

[0044] It should be noted that in this embodiment, the locking element 22 is specifically a button-type ball bearing pin; of course, in other embodiments, the locking element 22 can also be a locking bolt, locking buckle, or other locking structures. For the button-type ball bearing pin, it includes a button, pin, ball bearing, spring, and sleeve. The bottom of the sleeve has a through hole, the diameter of which is slightly smaller than the diameter of the ball bearing. The ball bearing and spring are inserted into the sleeve from the top. The pin passes through the sleeve, and the pin has a groove for installing the ball bearing.

[0045] The push-button steel ball pin has a locking mechanism and an unlocking mechanism. The locking mechanism works as follows: when the button is pressed, the pin moves within the sleeve under the action of a spring, causing a portion of the steel ball to move out of the through hole and abut against the bottom of the fixed stop 21, thus locking the pin in place. During this process, the pin will move the fixed pressure block 23, locking it against the fixed stop 21. The unlocking mechanism works as follows: when the button is pressed again, the pin moves in the opposite direction under the action of a spring, causing the steel ball to retract into the sleeve, thereby releasing the contact with the bottom of the fixed stop 21 and unlocking the pin. In other words, the fixed pressure block 23 will then release from the fixed stop 21, releasing the locking action.

[0046] Please continue to combine Figure 3 and Figure 4 In order to improve the clamping effect of the fixed pressure block 23 and protect the fixed stop block 21, in this embodiment, the workpiece fixing assembly 20 also includes a buffer pad 24. The buffer pad 24 is disposed between the fixed stop block 21 and the fixed pressure block 23, and the locking member 22 passes through the buffer pad 24.

[0047] It should be noted that, since the button-type ball bearing pin in this embodiment contains a ball bearing, and the pin can move the ball bearing up and down after being released from its locking position, please refer to the following for better securing of the ball bearing: Figure 5 , Figure 5 This is a schematic diagram of the structure of the buffer pad 24 provided in this embodiment, combined with... Figures 3-5 The buffer pad 24 is provided with a steel ball storage groove 241, which is located on the side of the buffer pad 24 near the fixed stop 21, and the locking member 22 passes through the steel ball storage groove 241.

[0048] In other words, after the button-type steel ball pin is released from its locking position, the steel ball can extend out of the through hole and abut against the side wall of the steel ball storage slot 241, thereby achieving fixation.

[0049] Please refer to Figure 6 , Figure 6 This is a structural schematic diagram of the tooling base plate 10 provided in this embodiment, combined with... Figure 3 , Figure 4 and Figure 6 In order to improve the installation stability of the fixed block 21, the tooling base plate 10 is also provided with at least two fixed grooves 12, which correspond one-to-one with at least two workpiece fixing components 20, and the fixed block 21 is set in the fixed groove 12.

[0050] To further improve the installation stability of the fixed block 21, a reinforcing groove 13 is provided on the bottom wall of the fixed groove 12, and the reinforcing groove 13 is provided through the tooling base plate 10; a reinforcing protrusion 211 is provided on the side of the fixed block 21 away from the fixed pressure block 23, the reinforcing protrusion 211 is provided in the reinforcing groove 13, and the locking member 22 passes through the reinforcing protrusion 211.

[0051] Please combine Figures 4-6 To facilitate the simultaneous fixing of the buffer pad 24 and the fixing block 21 onto the fixture base plate 10, in this embodiment, the buffer pad 24 is provided with a first mounting hole 242, the fixing block 21 is provided with a second mounting hole 212, and the bottom wall of the fixing groove 12 is provided with a third mounting hole 15. The first mounting hole 242, the second mounting hole 212, and the third mounting hole 15 are correspondingly provided. That is, fasteners such as pins or bolts can be simultaneously inserted into the first mounting hole 242, the second mounting hole 212, and the third mounting hole 15, thereby simultaneously fixing the buffer pad 24 and the fixing block 21 onto the fixture base plate 10, improving installation stability and ensuring the clamping effect of the fixing block 23 on the module workpiece 200.

[0052] To facilitate the installation of the locking member 22, in this embodiment, the fixing block 23 has a first mating hole 231, the buffer pad 24 has a second mating hole 243, and the fixing stop 21 has a third mating hole 213. The first mating hole 231, the second mating hole 243, and the third mating hole 213 are correspondingly provided. That is, the locking member 22 passes through the first mating hole 231, the second mating hole 243, and the third mating hole 213 simultaneously.

[0053] Please combine Figure 1 and Figure 6 The module workpiece fixing device 100 also includes a positioning pin 30, which is disposed on the bottom wall of the mounting groove 11. By setting the positioning pin 30, which cooperates with the positioning hole on the module workpiece 200, it can play a positioning role, which facilitates the installation of the module workpiece 200 and further improves the installation stability of the module workpiece 200.

[0054] Furthermore, the number of positioning pins 30 can be set to multiple. Multiple positioning pins 30 can be set near each workpiece fixing component 20, so as to cooperate with the workpiece fixing component 20 to fix one end of the module workpiece 200, thereby improving the fixing effect and thus improving production efficiency.

[0055] In addition, in order to facilitate the installation of the module workpiece 200 on the tooling base plate 10 and improve production efficiency, the tooling base plate 10 is also provided with an identification groove 14, which is used to indicate the installation direction of the module workpiece 200.

[0056] It should be noted that in this embodiment, the identification groove 14 is arrow-shaped, which facilitates the operator to correctly install the module workpiece 200 according to the direction of the arrow, thereby ensuring the accuracy of subsequent glue application. Of course, in other embodiments, the shape of the identification groove 14 can also be triangular, trapezoidal, Y-shaped, or V-shaped, etc., as long as the operator can normally identify the mark and ensure the correct installation of the module workpiece 200.

[0057] In summary, the embodiments of this utility model provide a modular workpiece fixing device 100, which includes a tooling base plate 10 and at least two workpiece fixing components 20. The tooling base plate 10 has a mounting groove 11 for mounting the modular workpiece 200. The at least two workpiece fixing components 20 are spaced apart on the tooling base plate 10 and are used to press the top of the modular workpiece 200 to fix the modular workpiece 200 in the mounting groove 11. By placing the modular workpiece 200 in the mounting groove 11 of the tooling base plate 10, the modular workpiece 200 can be limited in the left-right or front-back direction. Then, by pressing the top of the modular workpiece 200 with the workpiece fixing components 200, the modular workpiece 200 can be limited in the up-down direction. In this way, by utilizing the coordinated cooperation between the workpiece fixing component 20 and the tooling base plate 10, the module workpiece 200 is fixed in different directions, which improves its stability during subsequent transportation or gluing processes, avoids shaking during production operations, and ensures normal gluing of the gluing equipment, normal production of battery modules, and improves production efficiency.
