An automatic carbon rod loading device for battery assembly

Abstract

This invention relates to the field of carbon rod assembly technology, specifically to an automatic carbon rod loading device for battery assembly. The device includes a mounting plate with multiple support rods fixedly connected to its upper end. The mounting plate, support rods, and top plate form a frame. During assembly, the battery casing is placed in the workstation, and the carbon rod is placed inside a bellows. The bellows fixes the carbon rod in place, ensuring it aligns with the center of the battery casing. Rotating the lead screw lowers the lead screw nut, causing the connecting cylinder to stretch the bellows, moving the carbon rod into the battery casing. The connecting cylinder and bellows protect the carbon rod from contact with internal carbon powder, preventing breakage. When the connecting cylinder touches the bottom, a contact block presses against the bottom of the battery casing, pushing a force rod and a hydraulic rod to force liquid through a transmission pipe into the piston housing. This pushes the piston, causing the placement housing to retract into the receiving groove. The carbon rod falls to the bottom of the battery casing by gravity. Reverse rotation of the lead screw raises the carbon rod, gradually burying it and providing support. Simultaneously, the contact block disengages, and a spring returns to its original position, drawing the liquid back in, completing the assembly.

Description

Technical Field

[0001] This invention relates to the field of carbon rod assembly technology, specifically to an automatic carbon rod loading device for battery assembly. Background Technology

[0002] As the positive electrode current collector of dry cell batteries, the assembly quality of carbon rods directly affects the internal resistance, capacity and service life of the batteries. In the production of traditional paste-type or cardboard-type carbon batteries, carbon rods are usually installed horizontally in the center of a zinc cylinder filled with positive electrode powder.

[0003] In existing carbon rod assembly equipment, carbon rods are mostly inserted directly into the compacted carbon powder layer by horizontal pressing. Due to the high density and internal friction of carbon powder, the instantaneous resistance increases dramatically when the carbon rod is inserted quickly. Moreover, the carbon rod material is hard and brittle with low bending strength, making it very easy to break due to uneven force, or problems such as incomplete insertion or inconsistent depth may occur, which seriously affect the production yield and battery consistency. Although some equipment has tried to use simple rotation or vibration assistance, it still cannot effectively dissipate the dense carbon powder. The carbon rod still needs to rely on its own strength to squeeze the carbon powder, and the risk of breakage still exists. Summary of the Invention

[0007] Furthermore, a limiting rod is fixedly connected to the lower end of the top plate, a limiting block is slidably connected to the circumferential surface of the limiting rod, the limiting block is fixedly connected to the circumferential surface of the bellows, a moving rod is fixedly connected to one end of the limiting block, and an anti-detachment plate is fixedly connected to the lower end of the moving rod.

[0008] Furthermore, it also includes a vibration mechanism, which consists of a movable shell, a vibrating block, a stop block, a rebound groove, a force-bearing block, two mounting blocks, a first spring, and a horizontal rod. The movable shell is fixedly connected to the upper side of the mounting plate, the vibrating block is slidably connected inside the movable shell, the rebound groove is opened at one end of the movable shell, both mounting blocks are fixedly connected to one end of the movable shell, the horizontal rod is fixedly connected to the near ends of the two mounting blocks, the force-bearing block is fixedly connected to one end of the vibrating block and is slidably connected to the circumferential surface of the horizontal rod, the first spring is sleeved on the circumferential surface of the horizontal rod, and the stop block is rotatably connected to the upper end of the mounting plate through a rotating shaft, and the stop block abuts against the vibrating block.

[0009] Furthermore, it also includes a one-way drive mechanism, which consists of a power shaft, two friction plates, a transmission shaft, a rotating housing, a drive plate, a one-way plate, multiple second springs, multiple wedge blocks, and multiple right-angle blocks. The power shaft is rotatably connected to the lower end of the top plate, and the transmission shaft is rotatably mounted on the upper side of the mounting plate. The two friction plates are respectively fixedly connected to the adjacent ends of the rotating shaft and the transmission shaft.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. The device consists of a frame formed by a mounting plate, support rods, and a top plate. During assembly, the battery case is placed in the work position, and the carbon rod is placed inside the bellows. The bellows is used to fix the position and ensure that the carbon rod is aligned with the center of the battery case. Rotating the lead screw causes the lead screw nut to descend, which drives the connecting cylinder to stretch the bellows. The carbon rod moves into the battery case. The connecting cylinder and the bellows protect the carbon rod from contact with the internal carbon powder to prevent breakage. When the connecting cylinder touches the bottom, the contact block presses against the bottom of the battery case, pushing the force rod and hydraulic rod to force the liquid into the piston shell through the transmission pipe. This pushes the piston to retract the placement shell into the receiving groove, and the carbon rod falls to the bottom of the battery case by gravity. Rotating the lead screw in the opposite direction raises the carbon rod, and the carbon powder gradually buries the carbon rod to form support. At the same time, the contact block disengages, the spring returns to its original position, and the liquid is drawn back, completing the assembly.

[0014] 2. The servo motor output shaft is connected to the power shaft, which drives the lead screw to rotate automatically through the I-beam wheel and transmission belt. When the motor rotates clockwise (carbon rod descent process), the drive plate drives the wedge block to rotate. The wedge block contacts the right-angle block, and the friction plate drives the rotating shaft and the abutment block to rotate. The abutment block periodically impacts the vibrating block, applying vibration to the battery case, fluidizing the internal carbon powder, reducing insertion resistance. The first spring resets the vibrating block. When the motor rotates counterclockwise (ascending process), the wedge block contacts the inclined surface of the right-angle block, driving the right-angle block to move down and reset through the second spring. Power cannot be transmitted, and the vibration stops, preventing the carbon rod from tilting due to vibration. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to embodiments.

[0020] Example: An automatic carbon rod loading device for battery assembly, such as Figures 1-8 As shown, the system includes a mounting plate 1, with multiple support rods 101 fixedly connected to the upper end of the mounting plate 1. A top plate 102 is fixedly connected to the upper end of the support rods 101. A housing 103 is fixedly connected to the upper end of the mounting plate 1, and a battery housing 104 is housed inside the housing 103. A corrugated pipe 2 is fixedly connected to the lower end of the top plate 102, and a placement hole is provided at the upper end of the top plate 102. A connecting cylinder 202 is fixedly connected to the lower end of the corrugated pipe 2. Two sets of automatic placement mechanisms are provided on the circumferential surface of the connecting cylinder 202. The automatic placement mechanisms abut against the battery housing 104, and are positioned by vision and servo... The alignment system places the carbon rod inside the battery case 104. To improve the alignment accuracy between the carbon rod and the battery case 104, the present invention also provides a visual positioning and servo alignment system. Specifically, an industrial camera (not shown in the figure) is fixedly installed above the mounting plate 1. The camera is located directly above the battery case 104 station, and its optical axis is parallel to the carbon rod insertion direction. A ring LED light source is set around the camera to provide uniform illumination and ensure that the edge image of the battery case 104 opening is clear. The industrial camera is electrically connected to the controller, and the controller is connected to the servo motor 413 and the precision motion platform. The working process is as follows: After the battery case 104 is transported to the predetermined station, an industrial camera captures an image of the battery case 104. The image processing unit performs edge detection (e.g., using the Sobel operator) and feature extraction to calculate the center coordinates and angular attitude of the battery case 104. This is then compared with a preset reference position to obtain the deviation values ​​in the X-axis, Y-axis, and θ directions. The controller converts the image deviation into a compensation amount in mechanical coordinates based on the hand-eye calibration results, generating pulse commands to drive the servo motor 413. This causes the precision motion platform carrying the battery case 104 to perform precise compensation in the horizontal and rotational directions until the center of the battery case 104 coincides with the central axis of the carbon rod insertion mechanism. After alignment, the platform is locked, triggering the carbon rod insertion action. Through closed-loop control with visual feedback, it is ensured that the battery case 104 is in the ideal position before each insertion, effectively avoiding damage to the carbon rod caused by positioning errors. It should be noted that the calculation formula and method for the center coordinates and angular attitude of the battery case 104 can be selected and used by those skilled in the art. A lead screw 205 is rotatably connected to the lower end of the top plate 102. A lead screw nut 201 is threadedly connected to the circumferential surface of the lead screw 205. A drive block 203 is fixedly connected to the lower end of the lead screw nut 201. The drive block 203 is fixedly connected to the circumferential surface of the connecting cylinder 202. Each automatic placement mechanism consists of a placement shell 5, a mounting shell 501, a movable hole 502, a hydraulic shell 503, a force-bearing rod 504, a contact block 505, a hydraulic rod 506, a pull-back plate 507, a third spring 508, a transmission pipe 509, a piston shell 510, a piston plate 511, a piston rod 512, and a storage slot. The mounting shell 501 is fixedly connected to the circumferential surface of the connecting cylinder 202, and the storage slot is opened on the circumferential surface of the connecting cylinder 202. The piston shell 510 is fixedly connected to the inner wall of one side of the mounting shell 501, the piston plate 511 is slidably connected inside the piston shell 510, and the piston rod 512 is fixedly connected to the piston plate 503. One end of 11 is fixedly connected to one end of piston rod 512 with housing 5. Movable hole 502 is opened at the upper end of mounting housing 501. Hydraulic housing 503 is fixedly connected to the upper end of mounting housing 501. Hydraulic rod 506 is slidably connected inside hydraulic housing 503. Pull-back plate 507 is fixedly connected to the upper end of hydraulic rod 506. Third spring 508 is sleeved on the circumferential surface of hydraulic rod 506. Force rod 504 is fixedly connected to the lower end of hydraulic rod 506. Contact block 505 is fixedly connected to the lower end of force rod 504. Both ends of transmission pipe 509 are fixedly connected to the circumferential surfaces of hydraulic housing 503 and piston housing 510, respectively.

[0021] In a specific embodiment of the present invention, the entire device can be placed by the mounting plate 1, and the top plate 102 is supported by the support rod 101. When the battery needs to be assembled with carbon rods, the battery case 104 is first placed in the placement shell 103, and then the carbon rod is placed in the bellows 2. At this time, the carbon rod will be placed in the placement shell 5. Since the positions of the placement shell 103 and the bellows 2 are fixed, the relative positions of the battery case 104 and the carbon rod are very accurate after they are placed in the placement shell 103 and the bellows 2 respectively, so that the carbon rod is located in the center of the battery case 104. Then, the lead screw 205 is rotated, causing the lead screw nut 201, which is threaded onto its circumferential surface, to move downwards. Simultaneously, this moves the driving block 203 and connecting cylinder 202 downwards, stretching the bellows 2. At this time, the connecting cylinder 202 will drive the carbon rod to gradually move towards the center of the battery casing 104. Due to the protection provided by the connecting cylinder 202 and the bellows 2, the carbon powder inside the battery casing 104 does not contact the carbon rod, thus preventing breakage and damage. After the connecting cylinder 202 reaches the bottom of the battery casing 104, the contact block 505 will contact the bottom of the battery casing 104, causing the contact block 505 to... When 5 is pressed against, the force rod 504 and hydraulic rod 506 will move upward through the movable hole 502 and hydraulic shell 503 respectively. The movement of the force rod 504 will squeeze the liquid in the movable hole 502 outward and transfer the liquid to the piston shell 510 through the transmission pipe 509. At this time, the liquid will squeeze and press against the piston plate 511 and move to the left in the piston shell 510. The movement of the piston plate 511 will pull the piston rod 512 and the placement shell 5 to move into the storage groove. After the placement shell 5 moves into the storage groove, the carbon rod will be inserted into the bottom of the battery shell 104 by gravity. After insertion, the screw 205 is rotated in the opposite direction to move the screw nut 201 upward. At this time, the carbon powder will gradually come into contact with the carbon rod as the connecting cylinder 202 rises, thus gradually supporting and burying the carbon rod to prevent it from tipping over. After the contact block 505 rises, it will lose its support. At this time, the elastic pull of the third spring 508 will pull back the pull-back plate 507 and the hydraulic rod 506, drawing the liquid in the piston housing 510 back into the hydraulic housing 503 for convenient subsequent use.

[0022] Preferably, the clamping pressure of the placement shell 5 is relatively small, and the placement shell 5 itself is made of soft material. When the placement shell 5 rises, it will inevitably clamp the carbon rod. The soft material of the placement shell 5 and the characteristics of low clamping pressure can prevent the placement shell 5 from damaging the carbon rod.

[0023] Please refer to the details. Figure 1-8 A limiting rod 206 is fixedly connected to the lower end of the top plate 102. A limiting block 204 is slidably connected to the circumferential surface of the limiting rod 206. The limiting block 204 is fixedly connected to the circumferential surface of the bellows 2. A moving rod 106 is fixedly connected to one end of the limiting block 204. An anti-detachment plate 105 is fixedly connected to the lower end of the moving rod 106.

[0024] In this embodiment: when the bellows 2 extends and descends, it will simultaneously pull the limiting block 204, the moving rod 106 and the anti-detachment plate 105 down. The anti-detachment plate 105 can close the opening on one side of the housing 103 to prevent the battery housing 104 from accidentally falling out of the housing 103. The rotation of the limiting block 204 on the circumferential surface of the limiting rod 206 can indirectly prevent the lead screw nut 201 from rotating, thereby improving the movement stability of the lead screw nut 201.

[0025] Please refer to the details. Figure 1-8 It also includes a vibration mechanism, which consists of a movable shell 3, a vibrating block 303, abutting block 307, a rebound groove 301, a force-bearing block 302, two mounting blocks 304, a first spring 305, and a horizontal rod 306. The movable shell 3 is fixedly connected to the upper side of the mounting plate 1. The vibrating block 303 is slidably connected inside the movable shell 3. The rebound groove 301 is opened at one end of the movable shell 3. Both mounting blocks 304 are fixedly connected to one end of the movable shell 3. The horizontal rod 306 is fixedly connected to the near ends of the two mounting blocks 304. The force-bearing block 302 is fixedly connected to one end of the vibrating block 303 and is slidably connected to the circumferential surface of the horizontal rod 306. The first spring 305 is sleeved on the circumferential surface of the horizontal rod 306. The abutting block 307 is rotatably connected to the upper end of the mounting plate 1 through a rotating shaft and abuts against the vibrating block 303. It also includes a one-way drive mechanism, which consists of a power shaft 410, two friction plates 4, a transmission shaft 401, a rotating shell 402, a drive plate 403, a one-way plate 407, multiple second springs 406, multiple wedge blocks 408, and multiple right-angle blocks 409. The power shaft 410 is rotatably connected to the lower end of the top plate 102, and the transmission shaft 401 is rotatably mounted on the upper side of the mounting plate 1. The two friction plates 4 are respectively fixedly connected to the adjacent ends of the rotating shaft and the transmission shaft 401. The drive plate 403 and the rotating shell 402 are respectively fixedly connected to the adjacent ends of the power shaft 410 and the transmission shaft 401. Multiple second springs 406 are all fixedly connected to the lower inner wall of the rotating shell 402. The one-way plate 407 is fixedly connected to the upper end of the multiple second springs 406. Multiple right-angle blocks 409 are all fixedly connected to the upper end of the one-way plate 407. Multiple wedge blocks 408 are all fixedly connected to the lower end of the drive plate 403. Both the lead screw 205 and the drive shaft 410 are fixedly connected to I-beam pulleys 411. The circumferential surfaces of the two I-beam pulleys 411 are connected to a drive belt 412. A protective shell is fixedly connected to the upper end of the top plate 102. A servo motor 413 is fixedly connected to the upper end of the protective shell. The output end of the servo motor 413 is fixedly connected to the drive shaft 410. In this embodiment: the power generated by the rotation of the output end of the servo motor 413 is transmitted to the lead screw 205 through two I-beams 411 and a transmission belt 412, enabling the lead screw 205 to rotate automatically. On the other hand, the power shaft 410 will rotate following the output shaft of the servo motor 413. When the servo motor 413 rotates clockwise, it indicates that the lead screw nut 201 is in a descending state, which means that the carbon rod placement process is underway. The drive plate 403 will drive multiple wedge blocks 408 to rotate clockwise. Since the contact ends of the wedge blocks 408 and the right-angle blocks 409 are in direct contact, the rotation of the drive plate 403 will drive the rotating shell 402, the transmission shaft 401, and one of the friction plates 4 to rotate. Then, through another The friction transmission between the outer friction plate 4 and the friction plate 4 drives the rotating shaft and the abutment block 307 to rotate. At this time, the periodic abutment block 307 and the vibrating block 303 abut against each other, so that the vibrating block 303 can continuously contact the housing 103, apply vibration to the housing 103 and the battery housing 104, fluidize the carbon powder in the battery housing 104, reduce the resistance when the connecting cylinder 202 and the carbon powder in the battery housing 104 come into contact, and through the elastic expansion of the first spring 305, the force block 302 and the vibrating block 303 can be rebounded to the initial position, which facilitates the continuous left and right movement of the vibrating block 303. The force block 302 slides on the circumferential surface of the horizontal rod 306, which improves the horizontal movement stability of the force block 302 and the vibrating block 303. When the lead screw nut 201 needs to be moved upward, it means that the carbon rod has been placed. At this time, the output shaft of the servo motor 413 rotates counterclockwise. At this time, the contact surface of the wedge block 408 and the right-angle block 409 is inclined. When the drive plate 403 drives the multiple wedge blocks 408 to rotate, they will move downward against the multiple right-angle blocks 409 through the inclined surface. Through the elasticity of the second spring 406, the one-way plate 407 is periodically driven to move up and down. Therefore, it is impossible to transmit power to the drive shaft 401. As a result, the abutment block 307 and the rotating shaft no longer rotate, preventing the housing 103 and the battery housing 104 from vibrating, thereby preventing the carbon rod from tilting due to vibration after placement.

[0026] Please refer to the details. Figure 1-8 The inner circumferential wall of the rotating shell 402 is provided with multiple vertical grooves 404, and multiple vertical blocks 405 are fixedly connected to the circumferential surface of the one-way plate 407. The multiple vertical blocks 405 are slidably connected to the multiple vertical grooves 404 respectively. A suspension ring is rotatably connected to the circumferential surface of the drive shaft 401, and a connecting rod is fixedly connected between the circumferential surface of the suspension ring and one end of the mounting plate 1.

[0027] In this embodiment: when the one-way plate 407 moves, it can drive multiple vertical blocks 405 to slide in the vertical groove 404, thereby improving the vertical movement stability of the one-way plate 407. The drive shaft 401 and multiple components can be suspended and stabilized by the suspension ring and connecting rod.

[0028] Working principle: The entire device can be placed through the mounting plate 1, and the top plate 102 is supported by the support rod 101. When the battery needs to be assembled with carbon rods, the battery case 104 is first placed in the placement case 103, and then the carbon rod is placed in the bellows 2. At this time, the carbon rod will be placed in the placement case 5. Since the positions of the placement case 103 and the bellows 2 are fixed, the relative positions of the battery case 104 and the carbon rod are very accurate after they are placed in the placement case 103 and the bellows 2 respectively, so that the carbon rod is located in the center of the battery case 104. Then, the lead screw 205 is rotated, causing the lead screw nut 201, which is threaded onto its circumferential surface, to move downwards. Simultaneously, this moves the driving block 203 and connecting cylinder 202 downwards, stretching the bellows 2. At this time, the connecting cylinder 202 will drive the carbon rod to gradually move towards the center of the battery casing 104. Due to the protection provided by the connecting cylinder 202 and the bellows 2, the carbon powder inside the battery casing 104 does not contact the carbon rod, thus preventing breakage and damage. After the connecting cylinder 202 reaches the bottom of the battery casing 104, the contact block 505 will contact the bottom of the battery casing 104, causing the contact block 505 to... When 5 is pressed against, the force rod 504 and hydraulic rod 506 will move upward through the movable hole 502 and hydraulic shell 503 respectively. The movement of the force rod 504 will squeeze the liquid in the movable hole 502 outward and transfer the liquid to the piston shell 510 through the transmission pipe 509. At this time, the liquid will squeeze and press against the piston plate 511 and move to the left in the piston shell 510. The movement of the piston plate 511 will pull the piston rod 512 and the placement shell 5 to move into the storage groove. After the placement shell 5 moves into the storage groove, the carbon rod will be inserted into the bottom of the battery shell 104 by gravity. After insertion, the screw 205 is rotated in the opposite direction to move the screw nut 201 upward. At this time, the carbon powder will gradually come into contact with the carbon rod as the connecting cylinder 202 rises, thus gradually supporting and burying the carbon rod to prevent it from tipping over. After the contact block 505 rises, it will lose its support. At this time, the elastic pull of the third spring 508 will pull back the pull-back plate 507 and the hydraulic rod 506, drawing the liquid in the piston housing 510 back into the hydraulic housing 503 for convenient subsequent use.
