Description

Technical Field

[0001] This invention relates to a material feeding device, specifically a multi-station rotary material feeding device. Background Technology

[0002] During the processing of lithium battery covers, a feeding robot first places the lithium battery covers sequentially on multiple product stations set on a rotating indexing plate to restrict the horizontal movement of the lithium battery covers. During the pause interval of the rotating indexing plate, the product station receives the lithium battery covers placed by the feeding robot, and the lithium battery covers complete the processing steps during the pause interval of the rotating indexing plate. The processed lithium battery covers are then transferred as the rotating indexing plate rotates, and the unloading robot picks them up from the product station during the pause interval of the rotating indexing plate.

[0003] However, the above process has a drawback: during the process of the processed lithium battery cover being transferred as the rotary indexing plate rotates, due to inertia, at the instant of the rotary indexing plate's rotation, a relative motion occurs between the lithium battery cover and the product station on the rotary indexing plate, which can easily cause the processed lithium battery cover to fly off the product station and detach from the product station.

[0004] To address the aforementioned shortcomings, this application provides a multi-station rotary feeding device to solve the problem of lithium battery cover plates flying off the product station and detaching from the product station due to inertia. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-station rotary feeding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-station rotary feeding device includes an indexing rotary device, a product station, and an adsorption and transfer device.

[0008] The indexing rotary device includes an indexing rotary disk;

[0009] The product workstations are in multiple groups and are centrally symmetrically distributed on the edge of the indexing rotary table;

[0010] The adsorption and transfer device is located below the indexing rotary table. The adsorption and transfer device can generate an adsorption force on the products received in the adjacent product station on the indexing rotary table when it is stopped. The adsorption and transfer device moves with the rotation of the indexing rotary table to maintain the adsorption force on the products without interruption until the products are transferred to the unloading area, at which point the adsorption stops and the device moves back to its initial state.

[0011] Furthermore, the indexing rotation device also includes a divider, which is located below the indexing rotary disk. Its input end is provided with a synchronous wheel connected to a rotational power mechanism outside the device, and its output end is connected to the indexing rotary disk.

[0012] Furthermore, the product station includes a base plate, on which two sets of end positioning components are symmetrically arranged.

[0013] Furthermore, the end positioning assembly includes three sets of bearing seats arranged in a U-shape, and the bearing seats are provided with flange bearings.

[0014] Furthermore, the base plate is symmetrically provided with two sets of vacuum suction cups for adsorbing the product. The two sets of vacuum suction cups are connected to the vacuum channel inside the base plate, and the base plate is provided with a negative pressure interface that connects to the vacuum channel.

[0015] Furthermore, the adsorption and transfer device includes a first guide block and an adsorption and transfer mechanism;

[0016] The first guide block has multiple sets, each corresponding to a different product station, and is centrally symmetrically distributed on the indexing rotary table. The first guide block has a vertical channel inside, and the upper port of the vertical channel inside the first guide block is connected to the negative pressure interface pipe on the bottom plate of the product station corresponding to its body.

[0017] The adsorption and transfer mechanism can be connected to the lower port of the vertical channel inside the first guide block corresponding to the adjacent product station on the indexing rotary table when it is stopped, so that it can generate an adsorption force on the product received in the adjacent product station. The adsorption and transfer mechanism moves with the rotation of the indexing rotary table to maintain the adsorption force generated on the product without interruption until the product is transferred to the unloading area, at which point it stops adsorption and moves back to the initial state.

[0018] Furthermore, the adsorption and transfer mechanism includes a base, an arc-shaped guide rail, a slide, a cylinder, an air suction assembly, an arc-shaped rack, a reduction motor, and gears.

[0019] The base is located below the indexing rotary table;

[0020] The arc-shaped guide rail is mounted on the base via a column and is concentric with the indexing rotary table;

[0021] The slide blocks are in three sets and are slidably mounted on the arc-shaped guide rail. The central angle between adjacent slide blocks is equal to the central angle between adjacent first guide blocks, and a connecting rod is hinged between adjacent slide blocks.

[0022] The cylinder consists of three sets, each mounted on a separate set of slide blocks;

[0023] The intake assembly consists of three sets, each equipped with a piston end of a cylinder. Under the upward push of the corresponding cylinder, the three intake assemblies are connected to the lower ports of the vertical channels inside the three adjacent sets of first guide blocks on the indexing rotary disk when it is stopped.

[0024] The arc-shaped rack is mounted on any one of the sliding blocks and is concentric with the arc-shaped guide rail;

[0025] The geared motor is mounted on an adjacent base via a fixed seat;

[0026] The gear is located at the output end of the geared motor and meshes with the arc-shaped rack.

[0027] Furthermore, the suction assembly includes a second guide block and a rubber nozzle. The second guide block is disposed at the piston end of the cylinder. The second guide block has a right-angle channel inside. The side port of the right-angle channel inside the second guide block is connected to an external negative pressure device. The rubber nozzle is connected to the upper port of the right-angle channel inside the second guide block. The rubber nozzle is pushed upward by the cylinder to abut against the lower port of the vertical channel inside the first guide block corresponding to the indexing rotary disk when it is stopped.

[0028] Furthermore, the adsorption and transfer mechanism also includes a guide and limiting component for vertically guiding the piston end of the cylinder to push the second guide block upward and limiting its stroke.

[0029] Furthermore, the guide and limiting assembly includes an L-shaped guide block symmetrically arranged on both sides of the second guide block and an i-shaped limiting block mounted on the slide via a support. The horizontal portion of the lower end of the L-shaped guide block is located below the i-shaped limiting block, and the vertical portion of the L-shaped guide block is located inside the i-shaped limiting block, with their adjacent surfaces abutting.

[0030] Compared with the prior art, the present invention provides a multi-station rotary feeding device, which has the following advantages:

[0031] During the pause of the indexing rotary table, the adjacent adsorption and transfer device receives products placed by the loading robot. At this moment, the adsorption and transfer device exerts an adsorption force on the product received at its adjacent product station, completing the processing step. The adsorption and transfer device then moves along with the rotating indexing table to maintain an uninterrupted adsorption force on the product until it is transferred to the unloading area, at which point it stops adsorption and returns to its initial state. During the rotation of the indexing rotary table, because the adsorption and transfer device moves along with it to maintain an uninterrupted adsorption force on the product, the product is adsorbed onto the product station. Therefore, at the instant of the indexing rotation, the inertia of the product itself can be overcome, preventing relative movement between the product and the product station on the rotating indexing table, thus preventing the processed product from flying off the product station and detaching from it.

[0044] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1-2 The present invention provides a technical solution: a multi-station rotary feeding device, including an indexing rotary device 1, a product station 2, and an adsorption and transfer device 3.

[0046] The indexing rotation device 1 includes an indexing rotary disk 100, which can perform indexing rotation. There are multiple product stations 2, which are centrally symmetrically distributed on the edge of the indexing rotary disk 100. The adsorption and transfer device 3 is located below the indexing rotary disk 100. The adsorption and transfer device 3 can generate adsorption force on the products received in the adjacent product stations 2 on the indexing rotary disk 100 when it is stopped. The adsorption and transfer device 3 moves with the rotation of the indexing rotary disk 100 to maintain the adsorption force on the products without interruption until the products are transferred to the unloading area, at which point the adsorption stops and the device returns to its initial state.

[0047] During the pause of the indexing rotary table 100, the product station 2 of the adjacent adsorption and transfer device 3 receives the product placed by the loading robot. At this time, the adsorption and transfer device 3 generates an adsorption force on the product received in the adjacent product station 2, and during this gap, the product also completes the processing steps. Then, the adsorption and transfer device 3 moves with the rotation of the indexing rotary table 100 to maintain the adsorption force generated on the product so as not to be interrupted by the product rotating with the indexing rotary table 100, until the product is transferred to the unloading area to wait for the unloading robot to pick it up, at which point the adsorption stops and the movement returns to the initial state. During the rotation of the indexing rotary table, the adsorption and transfer device 3 moves along with the indexing rotary table 100 to maintain uninterrupted adsorption force on the product, ensuring the product is adsorbed onto the product station 2. Therefore, at the instant the indexing rotary table 100 rotates, the inertia of the product itself is overcome, preventing relative movement between the product and the product station 2 on the rotary table 100. This prevents the processed product from flying off the product station 2 and detaching from it. When the product is transferred to the unloading area as the indexing rotary table 100 rotates, the adsorption and transfer device 3 stops adsorption and returns to its initial state, awaiting the next round of adsorption and transfer of products within the product station 2.

[0048] Please see Figure 3In this embodiment, the indexing rotation device 1 further includes a divider 101, which is disposed below the indexing rotary disk 100. Its input end is equipped with a synchronous pulley 102 connected to an external rotary power mechanism, and its output end is connected to the indexing rotary disk 100. The synchronous pulley 102 is driven by the external rotary power mechanism, thereby causing the divider 101 to rotate in an indexing manner, thus realizing the indexing rotation of the indexing rotary disk 100. The rotation angle of the indexing rotary disk 100 each time is equal to the central angle between adjacent product stations 2. The rotary power mechanism includes a motor, pulleys, and a synchronous belt. The motor drives the pulleys, which in turn drive the synchronous pulley 102 via the synchronous belt. Thus, the rotary power mechanism drives the indexing rotation of the indexing rotary disk 100, achieving the indexing rotation. The rotary power mechanism is a conventional technique in the art and therefore does not require further detailed description.

[0049] Please see Figure 4 , Figure 5 , Figure 6 Product station 2 includes a base plate 200, on which two sets of end positioning components are symmetrically arranged, forming a feeding area for the product on the base plate 200. Specifically, the end positioning components include three sets of bearing seats 201 arranged in a U-shape, with flange bearings 202 mounted on the bearing seats 201. The unloading robot places the product in the feeding area on the base plate 200. The flange bearings 202 on the three sets of U-shaped bearing seats 201 make rolling contact with the three sides of the product's end. Utilizing the characteristics of the flange bearings 202, the product enters the feeding area on the base plate 200 without obstruction, achieving accurate positioning without scratches or jamming. In addition, two sets of vacuum suction cups 203 for adsorbing products are symmetrically arranged on the base plate 200. The vacuum suction cups 203 are located in the material feeding area on the base plate 200. The two sets of vacuum suction cups 203 are connected to the vacuum channel 204 inside the base plate 200, and the base plate 200 is provided with a negative pressure interface 205 that connects to the vacuum channel 204.

[0050] refer to Figure 2 , Figure 7 In this embodiment, the adsorption and transfer device 3 includes a first guide block 300 and an adsorption and transfer mechanism;

[0051] The first guide block 300 has multiple sets, each corresponding to a different product station 2, and is centrally symmetrically distributed on the indexing rotary disk 100. The first guide block 300 has a vertical channel inside, and the upper port of the vertical channel inside the first guide block 300 is connected to the negative pressure interface 205 pipe on the bottom plate 200 of the product station 2 corresponding to its body. Therefore, when there is negative pressure in the vertical channel inside the first guide block 300, the product in the corresponding product station 2 (the corresponding product station 2 is the product station 2 of the adjacent adsorption and transfer mechanism) can be adsorbed by two sets of vacuum suction cups 203.

[0052] The adsorption and transfer mechanism can be connected to the lower port of the vertical channel inside the first guide block 300 corresponding to the adjacent product station 2 on the indexing rotary disk 100 when it is stopped, so that it can generate an adsorption force on the product received in the adjacent product station 2. The adsorption and transfer mechanism moves with the rotation of the indexing rotary disk 100 to ensure that the adsorption force generated on the product is not interrupted as the product rotates with the indexing rotary disk 100, until the product is transferred to the unloading area, at which point the adsorption stops and the movement returns to the initial state.

[0053] During the pause of the indexing rotary table 100, the product station 2 of the adjacent adsorption and transfer mechanism receives the product placed by the loading robot. At this time, the product received in the adjacent product station 2 of the adsorption and transfer mechanism generates adsorption force, and the product also completes the processing steps within this gap. Then, the adsorption and transfer device 3 moves with the rotation of the indexing rotary table to maintain the adsorption force generated on the product without interruption until the product is transferred to the unloading area to wait for the unloading robot to pick it up, at which point the adsorption stops and the device moves back to the initial state. During the rotation of the indexing rotary table 100, the adsorption and transfer mechanism moves along with the rotation of the indexing rotary table 100 to ensure that the adsorption force on the product is not interrupted as the product rotates with the indexing rotary table 100. This allows the product to be adsorbed onto the product station 2. Therefore, at the instant of the indexing rotation of the indexing rotary table 100, the inertia of the product itself can be overcome, preventing relative movement between the product and the product station 2 on the indexing rotary table. This prevents the processed product from flying out of the unloading area on the base plate 200 in the product station 2 and detaching from the product station 2. When the product is transferred to the unloading area as the indexing rotary table 100 rotates, the adsorption and transfer mechanism stops adsorption and returns to its initial state, waiting for the next round of adsorption and transfer of products in the product station 2.

[0054] It should be further explained that the adsorption and transfer mechanism includes a base 301, an arc-shaped guide rail 302, a column 303, a slide 304, a connecting rod 305, a cylinder 306, an air suction assembly, an arc-shaped rack 307, a geared motor 308, a fixed seat 309, and a gear 310.

[0055] The base 301 is located below the indexing rotary disk 100. The arc-shaped guide rail 302 is mounted on the base 301 via a column 303 and is concentric with the indexing rotary disk 100. Three sets of slide blocks 304 are configured, each slidably mounted on the arc-shaped guide rail 302. The central angle between adjacent slide blocks 304 is equal to the central angle between adjacent first guide blocks 300. A connecting rod 305 is hinged between adjacent slide blocks 304. Each of the three sets of slide blocks 304 is equipped with the aforementioned cylinder 306, and the piston end of each of the three sets of cylinders 306 is equipped with the aforementioned suction assembly. Under the upward push of the corresponding cylinder 306, the intake components are respectively connected to the lower ports of the vertical channels inside the three adjacent first guide blocks 300 on the indexing rotary disk 100 when it is stopped. The arc rack 307 can be set on any one of the slides 304 and is concentric with the arc guide rail 302. In this embodiment, the arc rack 307 is set on the middle slide 304. The reduction motor 308 is set adjacent to the base 301 through the fixed seat 309. The gear 310 is set at the output end of the reduction motor 308 and meshes with the arc rack 307.

[0056] During the pause of the indexing rotary table at 100 degrees, the specific working process of the adsorption and transfer mechanism is as follows:

[0057] During the pause of the indexing rotary table 100, the three product stations 2 of the adjacent adsorption and transfer mechanism receive products placed by the loading robot. At this time, the three sets of cylinders 306 push the suction components upward, connecting the three suction components to the lower ports of the vertical channels of the three sets of first guide blocks 300. The suction components then start working, creating negative pressure in the vertical channels inside the three sets of first guide blocks 300. This causes the products in the corresponding three product stations 2 (i.e., the three product stations 2 of the adjacent adsorption and transfer mechanism) to be adsorbed by the vacuum suction cups 203, thus stabilizing the products in the product stations 2. During this pause, the products in the three product stations 2 complete the processing steps. Afterward, as the indexing rotary table 100 rotates three times, the reduction motor 308 drives the gear 310 to rotate, causing the arc-shaped rack 307 to rotate synchronously three times around the central axis of the indexing rotary table 100, with the same rotation angle each time. Thus, the three sets of cylinders 306 move along the arc-shaped guide rail 302 as the arc-shaped rack 307 rotates, ensuring that the three sets of suction components on the three sets of cylinders 306 and the lower ports of the vertical channels of the three sets of first guide blocks 300 remain connected during the indexing rotation of the indexing rotary table 100. This means that the three sets of first guide blocks 300 and the three sets of cylinders 306 corresponding to the three product stations 2 move synchronously without any change in distance. As a result, the products in the three product stations 2 are continuously adsorbed by the vacuum suction cup 203, and the adsorption is not interrupted as the products rotate with the indexing rotary table 100. Therefore, the products are adsorbed on the product station 2. So, at the moment of indexing rotation of the rotary table 100, the inertia of the products themselves can be overcome, so that there is no relative movement between the products and the product station 2 on the rotary table. This prevents the processed products from flying out of the feeding area on the bottom plate 200 in the product station 2 and detaching from the product station 2. As the product is transferred to the unloading area by the rotating indexing disk 100 and awaits to be picked up by the picking robot, the suction component stops suction and moves back to the origin with the cylinder 306. Then, the geared motor 308 drives the gear 310 to rotate in the reverse direction (the geared motor 308 drives the gear 310 to rotate in both forward and reverse directions, and drives the gear 310 to rotate step by step as the indexing disk 100 rotates, which are all conventional technical means in this field, so they will not be described in more detail). This causes the arc-shaped rack 307 to move back to its original position, and thus the three sets of cylinders 306 drive the three sets of suction components to move back to their original position along the guide of the arc-shaped guide rail 302. Finally, the adsorption and transfer mechanism returns to the initial state, waiting for the next round of adsorption and transfer of products in the product station 2.

[0058] It should be further explained that the suction assembly includes a second guide block 311 and a rubber nozzle 312. The second guide block 311 is located at the piston end of the cylinder 306. The second guide block 311 has a right-angle channel inside. The side port of the right-angle channel inside the second guide block 311 is connected to an external negative pressure device. The rubber nozzle 312 is connected to the upper port of the right-angle channel inside the second guide block 311. The rubber nozzle 312 is pushed upward by the cylinder 306 to abut against the second guide block 311 when paused. When the external negative pressure device performs suction, the rubber suction nozzle 312 generates suction force at the lower port of the vertical channel inside the first guide block 300 corresponding to the indexing rotary disk 100. Therefore, when the rubber suction nozzle 312 abuts against the lower port of the vertical channel inside the first guide block 300, it will generate negative pressure in the vertical channel inside the first guide block 300. Therefore, when there is negative pressure in the vertical channel inside the first guide block 300, the product in the corresponding product station 2 can be adsorbed by the two sets of vacuum suction cups 203.

[0059] In addition, the adsorption and transfer mechanism also includes a guide and limiting assembly for vertically guiding and limiting the stroke of the piston end of the cylinder 306 in pushing the second guide block 311 upward. Specifically, the guide and limiting assembly includes L-shaped guide blocks 313 symmetrically arranged on both sides of the second guide block 311 and C-shaped limiting blocks 315 mounted on the slide block 304 via supports 314. The horizontal portion of the lower end of the L-shaped guide block 313 is located below the C-shaped limiting block 315, thereby limiting the stroke of the piston end of the cylinder 306 in pushing the second guide block 311 upward. Furthermore, the vertical portion of the L-shaped guide block 313 is located inside the C-shaped limiting block 315, and the adjacent surfaces of the two are in contact, thereby providing vertical guidance for the piston end of the cylinder 306 in pushing the second guide block 311 upward, so as to keep the second guide block 311 moving upward smoothly without twisting.
