Description

Technical Field

[0001] This utility model belongs to the technical field of lead-acid battery production equipment, specifically relating to a vacuum counting mechanism for lead-acid battery plates. Background Technology

[0002] In the production process of lead-acid batteries, the positive and negative plates need to be grouped, stacked, assembled, and packaged according to strict quantity requirements. Furthermore, the accuracy of the lead-acid battery plate count directly affects the consistency of subsequent production processes and packaging. Existing counting and grouping methods rely entirely on manual visual operation, resulting in low efficiency. Operators frequently make errors in plate count due to fatigue or negligence, impacting subsequent processing and production. Simultaneously, long-term exposure to harmful substances such as lead dust by counting operators has adverse effects on their health. Additionally, the frequent contact between the lead-acid battery plates and personnel during manual counting can contaminate their surfaces, further affecting the quality of the lead-acid battery plates. Therefore, it is necessary to improve the existing lead-acid battery plate counting methods and devices. Utility Model Content

[0003] This utility model addresses the aforementioned problems by providing a vacuum counting mechanism for lead-acid battery plates that offers high accuracy in grouping and stacking counting, low labor intensity for operators, effectively improves production efficiency, ensures good operational safety, provides strong continuity of mechanism operation, and uses reliable lead-acid battery plates.

[0004] The technical solution adopted by this utility model is as follows: The vacuum counting mechanism for lead-acid battery plates includes a connecting plate. The connecting plate is characterized by: an inclined feeding conveyor on one side, the drive end of which is connected to the output end of a feeding conveyor motor on the other side of the connecting plate; vertically arranged battery plates to be grouped are stacked on top of the feeding conveyor; a downwardly arranged vacuum negative pressure conveying device is provided at the discharge end of the feeding conveyor, the drive end of which is connected to the output end of a vacuum negative pressure conveying motor on the other side of the connecting plate; the vacuum negative pressure conveying device is connected to a vacuum generator via a vacuum negative pressure connector; a stacking guide slide is provided at the lower discharge end of the vacuum negative pressure conveying device, and a group counting sensor is provided above the stacking guide slide; the group counting sensor is fixedly connected to the connecting plate via a sensor connecting frame.

[0005] The feeding and conveying device includes a feeding and conveying guide frame connected to the connecting vertical plate. A feeding and conveying drive sprocket and a feeding and conveying driven sprocket are rotatably mounted on the feeding and conveying guide frame. Two sets of parallel feeding and conveying annular chains are arranged between the feeding and conveying drive sprockets. The sprocket shaft of the feeding and conveying drive sprocket is also connected to the output end of the feeding and conveying motor. Feeding and conveying outer baffles are provided on the outer sides of the sprockets and chains. The feeding and conveying motor drives the feeding and conveying drive sprocket to rotate, thereby causing the two sets of feeding and conveying annular chains between the feeding and conveying drive sprockets to rotate continuously. Guided by the feeding and conveying guide frame on the inner side, the battery plates to be grouped, stacked on the upper side of the feeding and conveying annular chains, move forward to the vacuum negative pressure conveying device as the annular chains rotate. Then, the vacuum negative pressure conveying device conveys the battery plates to be grouped one by one to the grouping plate conveying line below.

[0006] A feeding gap adjusting block is provided on the feeding conveyor guide connecting frame at one end near the vacuum negative pressure conveying device, and the front end of the feeding conveyor annular chain passes through two chain through holes on the feeding gap adjusting block. The feeding gap adjusting block at the front end of the feeding conveyor device is used to adjust the distance between the front end of the feeding conveyor annular chain and the front side of the conveyor belt of the vacuum negative pressure conveying device, thereby facilitating the vacuum negative pressure conveying device to pick up the battery plates to be grouped one by one from the feeding conveyor device.

[0007] A feeding conveying adjusting sprocket is also provided between the feeding conveying drive sprocket and the feeding conveying driven sprocket, and at the lower part of the two sets of feeding conveying annular chains. The feeding conveying adjusting sprocket is movably arranged in the middle of the outer baffle of the feeding conveying via an adjusting wheel shaft. The tension of the feeding conveying annular chain can be adjusted by adjusting the vertical position of the feeding conveying adjusting sprocket, facilitating the flexible use of the device.

[0008] The vacuum negative pressure conveying device includes a negative pressure conveying connecting frame connected to the connecting plate. A negative pressure conveying driven pulley and a negative pressure conveying driving pulley are rotatably mounted at the upper and lower ends of the negative pressure conveying connecting frame, respectively. Two sets of perforated negative pressure conveying belts are arranged in parallel between the negative pressure conveying driven pulley and the negative pressure conveying driving pulley. The pulley shaft of the negative pressure conveying driving pulley is also connected to the output end of the vacuum negative pressure conveying motor. Furthermore, a vacuum negative pressure housing is provided between the negative pressure conveying driven pulley and the negative pressure conveying driving pulley, inside the perforated negative pressure conveying belt, for adsorbing the battery plates to be grouped onto the perforated negative pressure conveying belt. The vacuum negative pressure housing is sealed on the negative pressure conveying connecting frame through a negative pressure conveying outer plate and a sealing strip. The vacuum negative pressure connector communicates with the cavity inside the vacuum negative pressure housing through a vacuum negative pressure communication port provided on the negative pressure conveying connecting frame. The vacuum negative pressure transmission motor drives the negative pressure transmission drive pulley to rotate, thereby driving two sets of perforated negative pressure transmission belts set between the negative pressure transmission driven pulley and the negative pressure transmission drive pulley to rotate continuously from top to bottom. At the same time, a vacuum negative pressure connector connected to a vacuum generator creates a negative pressure vacuum state in the inner cavity of the vacuum negative pressure housing. This vacuum adsorption is then applied to the battery plates to be grouped on the front side of the vacuum negative pressure housing, which are in contact with the perforated negative pressure transmission belt, facilitating the movement of the battery plates to be grouped along the transmission belt and downward stacking guide slide.

[0009] The vacuum negative pressure housing includes a main body with a vacuum negative pressure inner cavity inside. The main body also has side plate mounting holes for connecting to the negative pressure conveying outer side plate. Furthermore, the front side of the main body facing the feeding conveyor has two sets of parallel front belt grooves. The front belt grooves also have several sets of vacuum negative pressure adsorption elongated holes arranged along the belt conveying direction, all of which communicate with the vacuum negative pressure inner cavity. The rear side of the main body has two sets of parallel rear belt grooves. Two sets of perforated negative pressure conveying belts between the driven and driven pulleys are respectively arranged in the front and rear belt grooves on the front and rear sides of the main body. The vacuum negative pressure inner cavity is sealed by the negative pressure conveying connecting frames and the negative pressure conveying outer side plates on both sides of the main body. The battery plates to be grouped are adsorbed one by one through the vacuum negative pressure adsorption elongated holes in the front belt grooves and the through holes on the perforated negative pressure conveying belts.

[0010] Below the stacking guide slide is a grouping electrode conveyor line for transporting grouped stacked battery electrodes. A stacking positioning baffle is also fixedly installed on the grouping electrode conveyor line at a position corresponding to the lower end of the stacking guide slide. The stacking positioning baffle positions the battery electrodes to be grouped, which, after being counted by the grouping counting sensor and falling via the stacking guide slide, onto the temporarily stopped grouping electrode conveyor line. When the required number of grouped stacked battery electrodes is reached, the grouping electrode conveyor line moves forward one step and stops again.

[0011] The beneficial effects of this utility model are as follows: Because this utility model employs an inclined feeding conveyor on one side of the connecting vertical plate, with its drive end connected to the output end of a feeding conveyor motor on the other side of the connecting vertical plate, and vertically arranged battery plates to be grouped stacked on top of the feeding conveyor; the discharge end of the feeding conveyor is equipped with a downwardly inclined vacuum negative pressure conveying device, the drive end of which is connected to the output end of a vacuum negative pressure conveying motor on the other side of the connecting vertical plate, and the vacuum negative pressure conveying device is connected to a vacuum generator via a vacuum negative pressure connector; the lower discharge end of the vacuum negative pressure conveying device is equipped with a stacking guide slide, and a group counting sensor is installed above the stacking guide slide.

Detailed Implementation

[0021] according to Figures 1-8The specific structure of this utility model is described in detail. The vacuum counting mechanism for lead-acid battery plates includes a connecting plate 1. A feeding conveyor 2, arranged at an angle with a lower front and higher rear, is located on one side of the connecting plate 1. The feeding conveyor 2 is composed of a feeding conveyor guide frame 13, which is fixedly connected to the connecting plate 1. A feeding conveyor drive sprocket 15 and a feeding conveyor driven sprocket 16 are rotatably mounted at the front and rear ends of the feeding conveyor guide frame 13, respectively. Two sets of parallel feeding conveyor annular chains 17 are also arranged between the feeding conveyor drive sprocket 15 and the feeding conveyor driven sprocket 16. The sprocket shaft of the feeding conveyor drive sprocket 15 is connected to the output end of a feeding conveyor motor 3 located on the other side of the connecting plate 1. An outer feeding conveyor baffle 14 is provided on the outer side of the feeding conveyor drive sprocket 15, the feeding conveyor driven sprocket 16, and the feeding conveyor annular chains 17. Several battery plates 4 to be grouped are placed vertically and stacked on the upper side of two feeding conveyor ring chains 17, and guided by the feeding conveyor guide connecting frames 13 on both sides and the feeding conveyor outer baffles 14. Then, the feeding conveyor motor 3 drives the feeding conveyor drive sprocket 15 to rotate, thereby driving the two sets of feeding conveyor ring chains 17 set between the feeding conveyor drive sprocket 15 and the feeding conveyor driven sprocket 16 to rotate continuously. Thus, under the guidance of the feeding conveyor guide connecting frames 13 on the inner side, the battery plates 4 to be grouped placed on the upper side of the feeding conveyor ring chains 17 move forward to the vacuum negative pressure conveying device 5 as the ring chains rotate. Then, the vacuum negative pressure conveying device 5 conveys the battery plates 4 to be grouped one by one to the grouping plate conveying line 11 below.

[0022] On the feeding conveying guide connecting frame 13 of the feeding conveying device 2, near the end of the vacuum negative pressure conveying device 5, a feeding gap adjusting block 19 is also provided; the front ends of the two feeding conveying ring chains 17 pass through the two chain through holes on the feeding gap adjusting block 19 respectively. Thus, the feeding gap adjusting block 19 provided at the front end of the feeding conveying device 2 is used to adjust the distance between the front end of the feeding conveying ring chain 17 (the discharge end at the front of the feeding conveying device 2) and the front side of the perforated negative pressure conveying belt 25 of the vacuum negative pressure conveying device 5. For example, the distance between the two is slightly greater than the thickness of a lead-acid battery plate, which facilitates the vacuum negative pressure conveying device 5 to pick up the battery plates 4 to be grouped from the feeding conveying device 2 one by one. Meanwhile, a feeding conveying adjusting sprocket 18 is also provided between the feeding conveying driving sprocket 15 and the feeding conveying driven sprocket 16, and at the lower part of the two sets of feeding conveying annular chains 17. The feeding conveying adjusting sprocket 18 is movably arranged on the lower side of the middle of the feeding conveying outer baffle 14 via the adjusting wheel shaft; so that the tension of the feeding conveying annular chain 17 can be adjusted by adjusting the vertical position of the feeding conveying adjusting sprocket 18, which facilitates the flexible use of the device.

[0023] At the lower discharge end of the feeding and conveying device 2, a vacuum negative pressure conveying device 5 is installed at an angle downwards. The vacuum negative pressure conveying device 5 includes a negative pressure conveying connecting frame 20 connected to the connecting vertical plate 1. The upper and lower ends of the negative pressure conveying connecting frame 20 are respectively rotatably equipped with a negative pressure conveying driven pulley 23 and a negative pressure conveying driving pulley 22. Two sets of perforated negative pressure conveying belts 25 are arranged in parallel between the negative pressure conveying driven pulley 23 and the negative pressure conveying driving pulley 22 (the holes in the conveying belts are used to adsorb the battery plates to be grouped by negative pressure vacuum). The pulley shaft of the negative pressure conveying driving pulley 22 is connected to the output end of the vacuum negative pressure conveying motor 6 located on the other side of the connecting vertical plate 1. Furthermore, a vacuum negative pressure housing 24 is provided on the inner side of the perforated negative pressure conveyor belt 25 between the negative pressure conveyor driven pulley 23 and the negative pressure conveyor driving pulley 22, for adsorbing the battery plates 4 to be grouped onto the perforated negative pressure conveyor belt 25. The vacuum negative pressure housing 24 is sealed on the negative pressure conveyor connecting frame 20 through the negative pressure conveyor outer plate 21 and the sealing strip. The vacuum negative pressure connector 7 connected to the vacuum generating device is connected to the cavity inside the vacuum negative pressure housing 24 through the vacuum negative pressure communication port 28 provided on the negative pressure conveyor connecting frame 20. Thus, the vacuum negative pressure transmission motor 6 drives the negative pressure transmission drive pulley 22 to rotate, thereby driving the two sets of perforated negative pressure transmission belts 25 arranged between the negative pressure transmission driven pulley 23 and the negative pressure transmission drive pulley 22 to rotate continuously from top to bottom; at the same time, the vacuum negative pressure connector 7 connected to the vacuum generator creates a negative pressure vacuum state in the inner cavity of the vacuum negative pressure housing 24, thereby vacuum adsorbing the battery plates 4 to be grouped on the front side of the vacuum negative pressure housing 24, which are in contact with the belt of the perforated negative pressure transmission belt 25, so that the battery plates 4 to be grouped can move downward along the transmission belt and the stacking guide slide 9.

[0024] In addition, the vacuum negative pressure housing 24 is composed of a housing body 30, the interior of which is provided with a vacuum negative pressure inner cavity 27. The housing body 30 is also provided with side plate mounting holes 32 for connecting with the outer negative pressure conveying outer plate 21. Furthermore, on the front side of the housing body 30 facing the discharge end of the feeding conveying device 2, there are two sets of parallel-arranged front belt grooves 31. The interior of the front belt grooves 31 is also provided with several sets of vacuum negative pressure adsorption elongated holes 29 arranged along the belt conveying direction, and each of the vacuum negative pressure adsorption elongated holes 29 is connected to the internal vacuum negative pressure inner cavity 27. The rear side of the housing body 30 is provided with two sets of parallel rear housing belt grooves 33; the two sets of perforated negative pressure conveying belts 25 between the negative pressure conveying driven pulley 23 and the negative pressure conveying driving pulley 22 are respectively arranged in the front housing belt grooves 31 and the rear housing belt grooves 33 on the front and rear sides of the housing body 30, and the vacuum negative pressure cavity 27 is formed into a sealed space by the negative pressure conveying connecting frame 20 on both sides of the housing body 30 and the negative pressure conveying outer plate 21 (including sealing strip), and the battery plates 4 to be grouped are adsorbed one by one through the vacuum negative pressure adsorption elongated holes 29 in the front housing belt groove 31 and the through holes on the perforated negative pressure conveying belts 25.

[0025] The lower discharge end of the vacuum negative pressure conveying device 5 is also equipped with an inclined stacking guide slide plate 9. Above the stacking guide slide plate 9 is a group counting sensor 8 for counting the downwardly conveyed battery plates. The group counting sensor 8 is fixedly connected to the connecting upright plate 1 via a sensor connecting bracket 26. Furthermore, below the stacking guide slide plate 9 is a group plate conveying line 11 for conveying the grouped stacked battery plates 12. A stacking positioning baffle 10 is also fixedly installed on the group plate conveying line 11 at a position corresponding to the lower end of the stacking guide slide plate 9. The stacking positioning baffle 10 on the group plate conveying line 11 is used to position and stack the battery plates 4 to be grouped after being counted by the group counting sensor 8 and falling through the stacking guide slide plate 9 onto the temporarily stopped group plate conveying line 11. When the number of grouped stacked battery plates 12 reaches the required quantity, the group plate conveying line 11 is controlled to move forward one step and then stop again.

[0026] When using this lead-acid battery plate vacuum counting mechanism, firstly, several battery plates 4 to be grouped are placed vertically and stacked on the upper side of the two feeding conveyor ring chains 17 of the feeding conveyor device 2. After the battery plates 4 to be grouped are placed, the feeding conveyor motor 3 is turned on, which drives the feeding conveyor drive sprocket 15 of the feeding conveyor device 2 to rotate, thereby driving the two sets of feeding conveyor ring chains 17 to rotate continuously. Thus, under the guidance of the feeding conveyor guide connecting frame 13 on both sides and the feeding conveyor outer baffle 14, the battery plates 4 to be grouped, which are stacked on the upper side of the feeding conveyor ring chains 17, can move forward to the vacuum negative pressure conveying device 5 as the ring chains rotate. Simultaneously, the vacuum negative pressure conveying motor 6 drives the negative pressure conveying drive pulley 22 of the vacuum negative pressure conveying device 5 to rotate, thereby driving the two sets of perforated negative pressure conveying belts 25 to rotate continuously from top to bottom. Moreover, the vacuum negative pressure connector 7 connected to the vacuum generator creates a negative pressure vacuum state in the inner cavity of the vacuum negative pressure housing 24 of the vacuum negative pressure conveying device 5. As a result, the battery plates 4 to be grouped, which fall one by one from the discharge end at the front of the feeding conveyor 2 onto the vacuum negative pressure conveying device 5, are vacuum-adsorbed onto the belt body of the perforated negative pressure conveying belt 25 on the front side of the vacuum negative pressure housing 24.

[0027] Subsequently, the battery plates 4 to be grouped move downwards along the drive belt towards the stacking guide slide 9. Once the battery plates 4 have moved downwards and left the adsorption area of ​​the vacuum negative pressure housing 24, they will slide down one by one from the stacking guide slide 9 at the lower end onto the temporarily stopped grouping plate conveyor line 11 under the influence of gravity. The falling battery plates are counted using the grouping counting sensor 8 to group and stack them according to the required quantity, forming grouped stacked battery plates 12 on the grouping plate conveyor line 11. Then, when the required number of grouped stacked battery plates 12 is reached, the feeding conveyor motor 3 and the vacuum negative pressure conveyor motor 6 are paused; afterwards, the grouping plate conveyor line 11 is controlled to move forward one step and then stop, preparing for the next grouping and stacking cycle.
