Description

Technical Field

[0001] This utility model belongs to the field of conveying and sorting technology, and in particular relates to a conveying and sorting mechanism. Background Technology

[0002] After the battery cells are manufactured, they are usually tested for efficiency and other properties, and then classified into different grades using a sorting machine. A fast-paced half-cell battery sorting machine, disclosed in Chinese Patent Publication No. CN222511127U, includes a sorting conveyor unit that transports battery cells along the X-direction, a cassette positioning bracket located on the Y-direction side of the sorting conveyor unit, several sorting suction and release units spanning above the sorting conveyor unit and the cassette positioning bracket, and a cassette replacement unit located below the cassette positioning bracket. Each sorting suction and release unit includes two alternating suction and release mechanisms: a first suction and release mechanism and a second suction and release mechanism. The first and second suction and release mechanisms are driven linearly by a first Y-direction translation module and a second Y-direction translation module, respectively. The first and second suction and release mechanisms alternately suction and release battery cells and place them into the cassette. This motion method is slow and inefficient, and can no longer meet production requirements.

[0003] To improve sorting efficiency, a belt conveyor sorting method is used. For example, in a battery cell cutting device announced in Chinese Patent Publication No. CN218695023U, the rocker arm suction mechanism and the belt conveyor mechanism are integrated, allowing the use of multiple material boxes. The rocker arm suction mechanism includes a suction drive motor, a rocker arm connected to the output shaft of the suction drive motor, and a lifting suction cup (which can be a Bernoulli suction cup) located at the lower end of the rocker arm. The belt conveyor mechanism includes a conveyor drive motor and a pair of parallel belts with vacuum suction cups driven by the conveyor drive motor. The lifting suction cup is located between the parallel belts, and the upper limit of the height of the lifting suction cup driven by the rocker arm is not lower than the bottom surface of the belt. When battery cells need to be suctioned and conveyed, the suction drive motor first drives the rocker arm to quickly lower the lifting suction cup. The process involves lowering the suction cup to pick up the battery cells, then rapidly raising it. Simultaneously, the vacuum of the parallel belt is activated while the vacuum of the lifting suction cup is deactivated. Both ends of the battery cells are held by the parallel belt, meaning the cells are quickly transferred from the lifting suction cup to the parallel belt and then conveyed to the next station. However, this solution uses two sets of adsorption control modules: a first module that controls the suction cup's adsorption and a second module that controls the belt's adsorption. These two modules operate sequentially. The first module controls the suction cup to pick up the battery cells, and then the second module controls the belt to ensure the battery cells are adsorbed onto the belt, allowing for the cell conveying process. This sequential operation of the two adsorption control modules reduces the conveying cycle time, resulting in low conveying efficiency.

[0004] Therefore, it is necessary to provide a conveying and sorting mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this invention is to provide a conveying and sorting mechanism that uses adsorption conveying, which reduces gas switching time, improves adsorption efficiency, and significantly increases conveying cycle time.

[0033] Please refer to Figures 1-7This embodiment is a conveying and sorting mechanism 100, which includes a mounting plate 1 and a conveying unit 2 disposed on the mounting plate 1. The conveying unit 2 includes a belt 27 conveyed along the length direction of the mounting plate 1. The bottom of the mounting plate 1 is provided with a receiving groove 11 extending along the length direction. A plurality of adsorption plates 3 are arranged in sequence in the receiving groove 11. The adsorption plates 3 are located above the conveying surface of the belt 27. A plurality of air inlets 12 are provided on the mounting plate 1. A plurality of air outlets 31 are provided on both the front and rear sides of the adsorption plates 3. A gas channel 32 is provided inside the adsorption plates 3, which communicates with the air inlets 12 and the air outlets 31. A plurality of first adsorption holes 33 and a plurality of second adsorption holes 34 are provided at the bottom of the adsorption plates 3, which communicate with the gas channel 32. A plurality of first adsorption holes 33 are arranged directly above the belt 27 for adsorbing the belt 27. A plurality of second adsorption holes 34 are arranged on the upper side of the belt 27 for adsorbing products.

[0034] The number of air inlets 12 on the mounting plate 1 corresponds one-to-one with the number of adsorption plates 3. Each adsorption plate 3 has several air outlets 31 on both its front and rear sides. Each air inlet 12 is connected to an air nozzle 6, and each air nozzle is equipped with a high-speed solenoid valve 7. The high-speed solenoid valve 7 is used to control the gas flow rate, which can accurately regulate the gas flow and has the characteristics of rapid response, enabling smooth switching and efficient transmission.

[0035] The adsorption plate 3 employs the Bernoulli adsorption principle. External compressed air is rapidly injected into the gas channel 32 through the air inlet 12 and then discharged through the air outlet 31. Due to the increased airflow velocity, Bernoulli's principle causes a decrease in air pressure within the gas channel 32, creating a low-pressure area between the first adsorption hole 33, the second adsorption hole 34, and the object. However, the surrounding air pressure is relatively high, pushing the object towards this low-pressure area. Thus, the object can be adsorbed without direct contact; the first adsorption hole 33 adsorbs the belt 27, while the second adsorption hole 34 adsorbs the battery cell 200, thereby adsorbing the battery cell 200 onto the belt 27. After the belt 27 adsorbs the battery cell 200, it transports the battery cell to its corresponding position. The air inlet 12, gas channel 32, first adsorption hole 33, and second adsorption hole 34 form an adsorption control module. Using a single adsorption control module replaces the traditional two sets of adsorption control modules, reducing gas switching time, improving adsorption efficiency, and significantly increasing the conveying cycle time. The adsorption plate 3 adopts the Bernoulli adsorption principle combined with the optimized layout of the first adsorption hole 33 and the second adsorption hole 34, which can stabilize the belt 27 and accurately adsorb the battery cell 200, reducing the failure rate of the conveying and sorting mechanism 100 during operation.

[0036] like Figure 5The diagram shows a cross-sectional view of the mounting plate 1 and the adsorption plate 3, with the cross-section in gray. Gaps 5 for gas outflow are provided on both the front and rear sides of the adsorption plate 3 and the walls of the receiving groove 11, allowing high-velocity gas to flow out quickly through the vent 31, thus creating a low-pressure area between the first adsorption hole 33, the second adsorption hole 34, and the object.

[0037] The structure of the air intake channel 32 is not limited here and can be set according to the actual situation. Since a lower area will be formed in the gas channel 32, it is necessary to ensure the airtightness of the gas channel 32 to prevent gas from entering or exiting from the contact point between the mounting plate 1 and the adsorption plate 3. Therefore, a sealing element 4 is provided at the contact point between the mounting plate 1 and the adsorption plate 3 to achieve a seal between the mounting plate 1 and the adsorption plate 3. Correspondingly, the adsorption plate 3 is provided with a mounting groove 35 for mounting the sealing element 4, or the mounting groove 35 can be set at the bottom of the mounting plate 1. This can be set according to the actual situation and is not limited here. The sealing element 4 has a ring structure and is set between the mounting plate 1 and the adsorption plate 3, which can ensure both the stability of the installation between the mounting plate 1 and the adsorption plate 3 and the airtightness between the mounting plate 1 and the adsorption plate 3.

[0038] In this embodiment, the sealing element 4 is a sealing ring. In other embodiments, the sealing element 4 may be configured with other structures, which are not limited here.

[0039] The adsorption plate 3 is detachably mounted in the receiving groove 11 of the mounting plate 1 by several first fasteners (not shown in the figure). Both the adsorption plate 3 and the mounting plate 1 are provided with first mounting holes 36 that mate with the first fasteners. Each adsorption plate 3 is provided with a product detection sensor 37. When the sensor 37 senses the product, it is determined that the adsorption plate 3 has adsorbed the product, and at this time, the conveying unit 2 conveys the product forward. Since the bottom surface of the adsorption plate 3 is used for adsorption, in order to avoid interference, the sensor 37 is mounted on the mounting plate 1, and the sensing end of the sensor 37 extends through the bottom of the adsorption plate 3. Correspondingly, both the adsorption plate 37 and the mounting plate 1 are provided with clearance holes 38 for the sensor 37 to pass through.

[0040] Mounting plate 1 and adsorption plate 3 are located between the upper drive section and the lower drive section of the belt, and the surface of the lower drive section of the belt is the conveying surface for conveying products.

[0041] The conveying unit 2 also includes a support base 21 disposed above the mounting plate 1, a drive motor 22 disposed on the support base 21, a drive shaft 23 driven by the drive motor 22 to rotate, a transmission assembly 24 disposed on the support base 21 and synchronously driven with the drive shaft 23, a first transmission shaft 25 disposed at one end of the mounting plate 1 and a second transmission shaft 26 disposed at the other end of the mounting plate 1, and a belt 27 is wound around the first transmission shaft 25, the transmission assembly 24 and the second transmission shaft 26 to realize rotational transmission.

[0042] In this embodiment, since two belts are arranged side by side, correspondingly, two rows of first adsorption holes 33 are arranged, located directly above the two belts 27, that is, a row of first adsorption holes 33 is arranged above each belt 27. Two rows of second adsorption holes 34 are arranged between the two belts 27, and each row of second adsorption holes 34 is close to the side of each belt 27.

[0043] In other embodiments, only one belt 27 may be provided, with a row of first adsorption holes provided directly above the belt 27, and several second adsorption holes 34 provided on the upper front and rear sides of the belt 27.

[0044] Therefore, the number of belts 27 and the number and arrangement of the first adsorption holes 33 and the second adsorption holes 34 are not limited here, and can be adjusted according to the actual situation.

[0045] The drive motor 22 is horizontally mounted on the support base 21, which can reduce the overall height of the conveying and sorting mechanism 100 and reduce the volume occupied.

[0046] The transmission assembly 24 includes a third transmission shaft 241 mounted on a support base 21, a first transmission wheel 242 sleeved in the middle of the third transmission shaft 241, and second and third transmission wheels 243 and 244 sleeved at both ends of the third transmission shaft 241. A fourth transmission wheel 231 is sleeved around the outer periphery of the drive shaft 23. A first transmission belt 245 is wound around the fourth transmission wheel 231 and the first transmission wheel 242 to achieve synchronous transmission between the drive shaft 23 and the transmission assembly 24. A first belt is wound around the second transmission wheel 243, and a second belt is wound around the third transmission wheel 244. The drive motor 22 drives the drive shaft 23 to rotate, which in turn drives the third transmission shaft 241 to rotate, thereby achieving rotational transmission between the two belts. To ensure the stability of the belt 27 transmission, several guide wheels 28 are also provided on the support base 21. The guide wheels 28 serve both a guiding function and the function of tensioning the belt 27 to ensure transmission stability.

[0047] When the conveying and sorting mechanism 100 provided in this solution is applied, the conveying and sorting mechanism 100 is set above the product conveying line, and several material boxes are set below the conveying and sorting mechanism 100. The conveying and sorting mechanism 100 is used to convey the products on the product conveying line to the corresponding material boxes according to the performance test results. When the sensor 37 senses the product, it is determined that the adsorption plate 3 has adsorbed the product. At this time, the conveying unit 2 conveys the product forward and into the corresponding material box.

[0048] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
