Abstract

This utility model discloses a battery production fixture, relating to the field of fixtures. It includes a fixed frame and a support fixedly connected to its top. A connecting plate is fixedly connected to the bottom of the fixed frame. A suction cup assembly connected to a distribution guide device is disposed in the middle of the bottom of the connecting plate. Supporting and dragging assemblies linked to the distribution guide device are symmetrically disposed on both sides of the bottom of the connecting plate. The fixture first drives the suction cup assembly through the distribution guide device to generate negative pressure adsorption force, achieving initial fixation of the battery body in a non-rigid manner. Compared to traditional rigid clamping, negative pressure adsorption avoids direct friction and compression between the fixture and the battery surface. The supporting and dragging assemblies are activated by the distribution guide device to support the battery body away from the bearing surface. After the supporting and dragging assemblies are activated and lifted, the suction cup assembly simultaneously releases the negative pressure adsorption effect. This completely avoids localized stress concentration caused by prolonged negative pressure, preventing irreversible deformation of the battery body due to continuous force, and further broadening the protection dimension of the battery structure.

Description

Technical Field

[0001] This utility model relates to the field of fixtures, and more particularly to a battery production fixture. Background Technology

[0002] In the field of battery production and processing, fixing the battery body is a key link to ensure the stable operation of processes such as transfer, assembly, and testing. At present, the mainstream battery fixing fixtures in the industry are mainly divided into two types of technical solutions: traditional rigid clamping and conventional negative pressure adsorption. However, both of them have significant defects in practical applications and cannot meet the requirements of battery structure protection and high-quality production. Traditional rigid clamping solutions apply clamping force to the battery body through rigid structures such as mechanical claws and rigid clamping plates. This can easily cause direct friction and squeezing with the fragile battery casing and tabs, resulting in scratches and functional failure. Furthermore, due to poor compatibility with different battery models, parameters need to be adjusted frequently, increasing operating costs. While conventional negative pressure adsorption solutions reduce rigid contact, they rely solely on negative pressure to fix the battery when it leaves the support surface, without any supporting structure. This can easily lead to localized stress concentration and irreversible deformation. Furthermore, the release of negative pressure and the support action are not synchronized, making it impossible to balance fixation reliability and structural protection. Both types of solutions affect battery production yield and safety, and are difficult to adapt to the industry's high-precision, low-damage processing requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a battery production fixture in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a battery production fixture, comprising a fixed frame and a support fixedly connected to its top end, a connecting plate fixedly connected to the bottom end of the fixed frame, a guide device installed inside the fixed frame, a suction cup assembly connected to the guide device being provided in the middle of the bottom end of the connecting plate, and support and dragging assemblies linked to the guide device being symmetrically arranged on both sides of the bottom end of the connecting plate, and an electric cylinder for controlling the opening and closing of the guide device being installed on the support; The suction cup assembly includes two connecting boxes installed at the bottom center of the connecting plate and connected to the distribution device. Each connecting box has several rubber suction cups installed at equal intervals at its bottom end and connected to it. The bearing assembly includes two sleeves that slide through both sides of the connecting plate. Both sleeves are connected to the guide device. Push rods are slidably connected to the inner side of the two sleeves. Hinges are installed on the lower side of both sleeves. Hinges are eccentrically hinged to the inner side of each hinge. The two push rods pass through the bottom end of the two sleeves and contact the hinge plates.

[0005] As a further description of the above technical solution: the guiding device includes a cylinder body fixedly installed inside the fixed frame, a partition plate fixedly installed inside the cylinder body, and a connecting rod slidably installed at the axis of the partition plate, passing through the top end of the cylinder body, and the top end of the connecting rod is fixedly connected to the output shaft of the electric cylinder.

[0006] As a further description of the above technical solution: a piston seat is fixedly connected to the bottom end of the connecting rod, and an air outlet is symmetrically opened on the lower side of the outer surface of the piston seat near the middle of the cylinder body, which is adapted to the air outlet.

[0007] As a further description of the above technical solution: a piston plate is installed on the outside of the connecting rod, and two hoses are symmetrically installed on the upper side of the outer surface of the cylinder away from the middle, with the ends of the two hoses away from the cylinder extending through to the inner side of the two sleeves respectively.

[0008] As a further description of the above technical solution: two air guide pipes are fixedly connected between the two connecting boxes and the lower side of the cylinder body cavity, and both air guide pipes are connected to the air dissipation hole.

[0009] As a further description of the above technical solution: a piston block adapted to slide inside the sleeve is fixedly installed at the top of the push rod, and a compression ball is fixedly installed at the end of the push rod near the hinge plate.

[0010] As a further description of the above technical solution: a spring is placed at the bottom of the inner side of the sleeve, and the two ends of the spring abut against the piston block and the bottom of the inner cavity of the sleeve, respectively.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The clamp first drives the suction cup assembly through the guide device to generate negative pressure adsorption force, and achieves the initial fixation of the battery body in a non-rigid manner. Compared with traditional rigid clamping, negative pressure adsorption can avoid direct friction and squeezing between the clamp and the battery surface, accurately protect the battery shell, tabs and other vulnerable structures, and reduce the risk of appearance scratches or functional failure from the source. At the same time, the supporting component is activated by the distribution device to support the battery body that has left the bearing surface. After the supporting component is activated to lift, the suction cup component releases the negative pressure adsorption effect simultaneously, which can completely avoid the local stress concentration caused by the long-term action of negative pressure, prevent the battery body from undergoing irreversible deformation due to continuous force, and further broaden the protection dimension of the battery structure.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 and Figure 2 As shown, the present invention provides a battery production fixture, including a fixed frame 1 and a support 2 fixedly connected to its top. A connecting plate 3 is fixedly connected to the bottom end of the fixed frame 1. A guide device 5 is installed inside the fixed frame 1. A suction cup assembly 6 connected to the guide device 5 is provided in the middle of the bottom end of the connecting plate 3. Supporting and dragging assemblies 7 linked to the guide device 5 are symmetrically arranged on both sides of the bottom end of the connecting plate 3. An electric cylinder 4 for controlling the opening and closing of the guide device 5 is installed on the support 2.

[0016] When clamping the battery body, the electric cylinder 4 drives the suction cup assembly 6 to adsorb and fix the battery body under negative pressure through the guide device 5. After the suction cup assembly 6 lifts the battery body off the ground, the electric cylinder 4 drives the two support components 7 to move closer to each other through the guide device 5, so that the two support components 7 support the bottom of the battery body. This avoids damage to the battery body caused by excessive clamping force or hard contact of the clamp. By combining non-rigid adsorption and support contact, damage to the battery body caused by excessive clamping force or hard collision of the clamp is avoided, ensuring the safety and stability of the clamping process.

[0017] Specifically, such as Figure 1 - Figure 3 As shown, the distribution device 5 includes a cylinder 51 fixedly installed inside the fixed frame 1. A partition 52 is fixedly installed inside the cylinder 51. A connecting rod 53 is slidably installed at the axis of the partition 52, passing through the top end of the cylinder 51. The top end of the connecting rod 53 is fixedly connected to the output shaft of the electric cylinder 4. The bottom end of the connecting rod 53 is fixedly connected to a piston seat 55. The outer surface of the piston seat 55 is provided with a vent hole 551. The lower side of the outer surface of the cylinder 51 near the middle is symmetrically provided with an air outlet 552 that matches the vent hole 551. The suction cup assembly 6 includes two connecting boxes 61 installed at the bottom center of the connecting plate 3 and connected to the guide device 5. Each connecting box 61 has a plurality of rubber suction cups 62 installed at equal intervals at its bottom and connected thereto. Two air guide pipes 63 are fixedly connected between the two connecting boxes 61 and the lower side of the inner cavity of the cylinder 51, and both air guide pipes 63 are connected to the air diffuser 551. When the electric cylinder 4 is started, the output shaft of the electric cylinder 4 pulls the connecting rod 53 and drives the piston seat 55 upward, thereby generating negative pressure in the lower inner cavity of the cylinder body 51. In this way, the air in the connecting box 61 is sucked out through the connecting rod 53, so that the rubber suction cup 62 at the bottom of the connecting box 61 is firmly attracted to the negative pressure of the battery body. After the rubber suction cup 62 adheres to the battery body, the device removes the battery body from the bearing surface. Then, the electric cylinder 4 is activated again to pull the connecting rod 53 upward. At this time, the supporting component 7 supports the battery body, and the vent hole 551 on the piston seat 55 aligns with the air outlet 552 on the cylinder body 51. At this time, external air enters the connecting box 61 through the vent hole 551, releasing the adsorption effect between the rubber suction cup 62 and the battery body.

[0018] Specifically, such as Figure 2 - Figure 5As shown, the bearing assembly 7 includes two sleeves 71 that slide through both sides of the connecting plate 3. Both sleeves 71 are connected to the guide device 5. Push rods 72 are slidably connected to the inner side of the two sleeves 71. Hinges 75 are installed on the lower side of both sleeves 71. Hinges 76 are eccentrically hinged to the inner side of each hinge 75. The two push rods 72 respectively pass through the bottom end of the two sleeves 71 and contact the hinge plates 76. A piston plate 54 is installed on the outside of the connecting rod 53. Two hoses 541 are symmetrically installed on the upper side of the outer surface of the cylinder 51 away from the middle. The ends of the two hoses 541 away from the cylinder 51 extend through to the inside of the two sleeves 71 respectively. A piston block 73 adapted to slide inside the sleeve 71 is fixedly installed at the top of the push rod 72, and a compression ball 74 is fixedly installed on the end of the push rod 72 near the hinge plate 76. A spring 77 is placed at the bottom of the inner side of the sleeve 71, and the two ends of the spring 77 abut against the piston block 73 and the bottom of the inner cavity of the sleeve 71, respectively. When the connecting rod 53 moves upward, the piston plate 54 on its outer surface pushes the air on the upper side of the inner cavity of the cylinder 51 through the hose 541 into the two sleeves 71 respectively. Thus, high pressure is formed inside the sleeves 71. The high pressure pushes the piston block 73 to drive the extrusion ball 74 at the bottom of the push rod 72 to push the hinge plate 76 to rotate downward. The two hinge plates 76 rotate towards each other, thereby lifting the battery body. After the lifting is completed, the piston block 73 is pushed upward by the spring 77 to reset. After the piston block 73 is reset, the high pressure gas inside the sleeve 71 is re-entered into the upper side of the inner cavity of the cylinder 51, so that the piston plate 54 and the connecting rod 53 are reset together.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
