Description

Technical Field

[0001] The utility model relates to automation equipment, in particular to product turning equipment and a product conveying line comprising the same. Background Art

[0002] At present, in the process flow of many products, it is necessary to turn the products over. For example, in the field of pharmaceutical packaging, medicine boxes need to be turned over so that the anti-counterfeiting barcode on the medicine box can be scanned by a barcode scanner. The traditional way of turning the medicine boxes over is to turn them over manually one by one, which requires a lot of manpower to achieve mass production, is inefficient, consumes a lot of labor, and has a low degree of automation.

[0003] For another example, in the field of new energy packaging, the photovoltaic module junction box also needs to be turned over in its automated production line. Specifically, the current junction boxes are mainly divided into two types, one is a product with a connecting wire in the box body (i.e., a wired junction box), and the other is a product that only retains the structure of the box body itself (i.e., a wireless junction box). Among them, the wired junction box is used to be installed on both sides of the photovoltaic module board to form an output terminal, and the wireless junction box is used to be installed in the middle of the photovoltaic module board to form a current path. Before installation, the above-mentioned junction boxes need to ensure the accuracy of their front and back positions, so as to ensure the accuracy of the position when the manipulator or other grasping components are carrying the junction box. The traditional method is to convert the disorderly arranged wired junction boxes into orderly arranged wired junction boxes, and feed the placed orderly arranged wired junction box racks to the feeding mechanism, wherein "disorderly conversion to orderly" means that the junction boxes with mixed front and back placements are always arranged on the platform to be picked up with the front side facing up, but this method requires manual cooperation to ensure the accuracy of feeding, the degree of automation of the equipment is low, and for the long-term use of the equipment, the labor cost is high, and the overall process flow is relatively cumbersome.

[0037] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0043] The terms used in this document generally have the ordinary meaning of each term used in this field, in the context of the case and in the specific context, unless otherwise noted. Certain terms used to describe the present invention will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the present invention.

[0044] The terms "front", "back", "up", "down", "left", "right", etc. used in this article are all directional terms. In this case, they are only used to illustrate the positional relationship between the various structures, and are not used to limit the protection plan of this case and the specific direction during actual implementation.

[0045] This embodiment provides a product flipping device. It can be understood that the product can be a box body, a plate structure, a column structure, etc. For the sake of simplicity, this embodiment will take the wired junction box used in photovoltaic modules as an example to further explain the structure and principle of the product flipping device in detail.

[0046] like Figure 1 As shown, it is a schematic diagram of the structure of a wired junction box in the prior art. The box body of the wired junction box has a connecting wire wound in a ring shape. Due to the influence of the connecting wire, there are two states of front facing and reverse facing. The wired junction box needs to be transformed from the reverse facing wired junction box to the positive facing wired junction box in its conveyor line, so that the subsequent robot arm can clamp the front facing wired junction box and install it to the corresponding position on the photovoltaic panel.

[0047] like Figure 2 and Figure 4 As shown, the product turning device in this embodiment includes a clamping belt group 0, which includes a first conveying unit 1 and a second conveying unit 2 arranged in parallel and spaced apart in the upper and lower directions, and the first conveying unit 1 and the second conveying unit 2 each include a closed-loop conveyor belt 15, and the closed-loop conveyor belt 15 can ensure the continuous transmission action of the first conveying unit 1 and the second conveying unit 2; wherein the first conveying unit 1 and the second conveying unit 2 are arranged spaced apart in the vertical direction, and the first conveying unit 1 and the second conveying unit 2 are driven to perform a clamping action to move closer to each other or an opening action to move away from each other.

[0048] When the wired junction box moves to the first conveying unit 1 or the second conveying unit 2, and the wired junction box needs to be flipped, the first conveying unit 1 and the second conveying unit 2 move closer to each other until the surfaces of the two conveying units contact the wired junction box, and the wired junction box remains stable and does not slide under the clamping action of the two conveying units, so that the first conveying unit 1 and the second conveying unit 2 can drive the wired junction box to flip.

[0049] When the wired junction box is flipped, in order to achieve the purpose of transporting the wired junction box to the downstream equipment, the first conveying unit 1 and the second conveying unit 2 in the clamping state move away from each other, so that one of the first conveying unit 1 or the second conveying unit 2 is separated from the wired junction box, and then the other conveying unit where the wired junction box is located transports the wired junction box to the downstream equipment.

[0050] In this embodiment, the first conveying unit 1 and the second conveying unit 2 are flipped to exchange the upper and lower positions, and the first conveying unit 1 or the second conveying unit 2 located at the bottom serves as the actual conveying surface 5 of the product, and conveys the wired junction box with the positive direction along the product transportation direction. In other words, the two conveying units can realize the conveying action.

[0051] Optionally, when the conveying direction of the product is from right to left, the closed-loop conveyor belts of the first conveying unit 1 and the second conveying unit 2 both rotate counterclockwise.

[0052] In this embodiment, Figure 2As shown, when the conveying direction of the product is from left to right, the closed-loop conveyor belts 15 of the first conveying unit 1 and the second conveying unit 2 both rotate clockwise.

[0053] It can be understood that the conveying direction of the above-mentioned products is the movement direction of the products on the conveyor line from the upstream equipment to the downstream equipment.

[0054] Considering that each conveying unit needs to be driven by a driving device to complete the conveying action, and the setting position of the driving device must not interfere with the upstream and downstream equipment, preferably, the driving device is an electric roller, which can be directly connected to the cable to realize the driving of the first conveying unit 1 and the second conveying unit 2, effectively saving installation space.

[0055] The first conveying unit 1 and the second conveying unit 2 each include two brackets 11 arranged opposite to each other, each bracket 11 has a first through slot 12 and a second through slot 13 on both sides, the two first through slots 12 of the two brackets 11 are arranged opposite to each other, and the two second through slots 13 of the two brackets 11 are arranged opposite to each other, forming a roller channel between the two first through slots 12 and between the two second through slots 13, a roller 14 movable along the conveying direction of the wired junction box is arranged in the roller channel, and a closed-loop conveyor belt 15 is arranged between the two rollers 14, and the wired junction box is transported on the closed-loop conveyor belt 15 of the first conveying unit 1 or the second conveying unit 2.

[0056] Further, such as Figure 3 As shown, each bracket 11 has an adjustment hole 111 on both sides, and the adjustment hole 111 is located in the groove wall of the first groove 12 and / or the second groove 13, and is connected to the first groove 12 and / or the second groove 13, and an adjustment member is provided in the adjustment hole 111, and the adjustment member is connected to the corresponding roller 14 through the adjustment hole 111, and drives the roller 14 to move, so as to change the distance between the two rollers 14 of each bracket 11, and adjust the tension of the closed-loop conveyor belt 15 located on the two rollers 14 accordingly.

[0057] In a specific implementation manner, the adjusting member is a bolt, which can be connected to the roller shaft 14 through the above-mentioned adjusting through hole 111. Correspondingly, the portion of the roller shaft 14 located inside the first through groove 12 or the second through groove 13 has a screw hole adapted to the bolt. The tension of the closed-loop conveyor belt 15 can be adjusted by rotating the bolt, thereby preventing the closed-loop conveyor belt 15 from being offset and loosened.

[0058] like Figure 5As shown, the clamping belt group 0 also includes a clamping device 3, which is used to realize the relative movement between the first conveying unit 1 and the second conveying unit 2. The number of the clamping devices 3 is two groups, and the two groups of clamping devices 3 are relatively arranged on both sides of the clamping belt group 0, and each clamping device 3 has a first clamping member 31 and a second clamping member 32, the first clamping member 31 clamps and fixes one side of the first conveying unit 1, and the second clamping member 32 clamps and fixes the other side of the second conveying unit 2; and the clamping device 3 also includes a second driving mechanism 33, and the first clamping member 31 and the second clamping member 32 can drive the first conveying unit 1 and the second conveying unit 2 to move away from each other or closer to each other through the drive of the second driving mechanism 33.

[0059] Optionally, the second driving mechanism 33 is a finger cylinder.

[0060] Optionally, both the first clamping member 31 and the second clamping member 32 may be claws.

[0061] Taking into account the positional relationship between the product turning device and the upstream device and the downstream device before and after the product turning device is turned over, preferably, each clamping device 3 is arranged at the middle position of the clamping belt group 0. Therefore, the position of the product turning device before and after the turning will not change, which can save a series of operations of adjusting the position of the upstream device and / or downstream device due to the change of the product turning device before and after the turning.

[0062] Each clamping device 3 is fixedly connected to the output end of the first driving mechanism 4, and the two groups of clamping devices 3 are driven by the first driving mechanism 4 to perform flipping motion around a horizontal flip axis. Since each clamping device 3 is driven by the first driving mechanism 4, the two groups of clamping devices 3 can rotate synchronously, thereby driving the clamping belt group 0 to flip.

[0063] In this embodiment, the turning angle of the pinching belt set 0 is 180 degrees.

[0064] Specifically, the horizontal flip axis is determined by the position of the first driving mechanism 4 . Since the first driving mechanism 4 is fixedly connected to the clamping device 3 , the horizontal flip axis in this embodiment is located in the middle of the clamping belt group 0 .

[0065] like Figure 6As shown, the first driving mechanism 4 includes a transmission part 41 and a driving part 42, the transmission part 41 includes at least two synchronous pulleys and a synchronous belt for connecting the plurality of synchronous belt paths. In this embodiment, the number of synchronous pulleys is two, namely a first synchronous pulley 412 and a second synchronous pulley 413, wherein the first synchronous pulley 412 is fixed to the clamping device 3, and the second synchronous pulley 413 is fixedly arranged on a mounting plate 43; the driving part 42 is fixedly arranged on the mounting plate 43, and the driving part 42 has a driving end 421, a connecting plate 46 slidably arranged on the mounting plate 43 is provided between the driving end 421 and the synchronous belt 411, and the sliding defense line of the connecting plate 46 is consistent with the transmission direction of the transmission part 41. Optionally, a guide rail 45 is provided on the mounting plate 43, and the extension direction of the guide rail 45 is consistent with the transmission direction of the transmission part 41, and the connecting plate 46 moves linearly on the guide rail 45; the connecting plate 46 has a first end and a second end, the first end is fixedly connected to the driving end 421, and the second end clamps and fixes the synchronous belt 411.

[0066] In this embodiment, considering that in most application scenarios, the product flipping device and the upstream device and the downstream device are located on the same horizontal plane, in order to avoid interference between the mounting plate 43 and the upstream device and / or the downstream device, the mounting plate 43 is located below the product flipping device.

[0067] When the product needs to be flipped, the driving part 42 works and drives the driving end 421 to be pushed upward, and the driving end 421 drives the connecting plate 46 to move upward along the guide rail 45 through the first end of the connecting plate 46, and the second end of the connecting plate 46 clamps and fixes the synchronous belt 411, and the synchronous belt 411 drives the first synchronous pulley 412 and the second synchronous pulley 413 to rotate; wherein, when the first synchronous pulley 412 fixedly connected to the clamping device 3 rotates, it drives the clamping device 3 to rotate together, and then the clamping device 3 drives the clamping belt group 0 to perform a flipping action.

[0068] Optionally, the driving part 42 is a cylinder, and the first driving mechanism can drive the pinching belt group 0 to rotate through the cylinder, which has lower cost compared to motor drive.

[0069] Furthermore, the first driving mechanism 4 also includes a buffer portion 44, which is fixedly disposed on the mounting plate 43; the buffer portion 44 has a buffer member for mitigating the impact of the collision between the connecting plate 46 and the buffer portion 44, and the buffer member is disposed at the starting end of the sliding path of the connecting plate 46.

[0070] Specifically, when the flipping is completed, the driving part 42 stops working, and the connecting plate 46 returns to its original position to the starting end of the sliding path of the connecting plate 46, that is, the bottom end of the guide rail 45 in this embodiment, and waits for the next upward movement; before the connecting plate 46 falls back and stops, the connecting plate 46 first contacts the buffer, which can buffer the impact force when the connecting plate 46 falls back, thereby avoiding the connecting plate 46 from colliding with the driving part 42 and generating a large impact.

[0071] Optionally, the buffer portion 44 is a hydraulic buffer.

[0072] like Figure 7 As shown, this embodiment also provides a product conveyor line, including an inlet conveyor line body 6, a product turning device and an outlet conveyor line body 7 for detection and arrangement; wherein, the wired junction box enters from the inlet conveyor line body 6, and is directly conveyed to the outlet conveyor line body by the first conveying unit 1 or the second conveying unit 2 located below, or is turned over by the product turning device, and then conveyed to the outlet conveyor line body by the first conveying unit 1 or the second conveying unit 2 located below.

[0073] Furthermore, in order to determine the orientation of the wired junction box and then determine whether the wired junction box needs to be flipped, the present embodiment also includes a visual detection mechanism for detecting the orientation of the product, and the visual detection mechanism is arranged above the feed conveying line 6; the visual detection mechanism is electrically connected to the clamping belt group 0, and the visual detection mechanism sends a first signal and a second signal to the clamping belt group 0 according to whether the orientation of the product detected by it is forward or reverse; the clamping belt group 0 receives the first signal, and the first conveying unit 1 or the second conveying unit 2 below conveys the corresponding product along the product transportation direction; the clamping belt group 0 receives the second signal, and the clamping belt group 0 is driven by the clamping device 3 to perform a flipping movement around the horizontal flipping axis, and after flipping, the first conveying unit 1 or the second conveying unit 2 below conveys the corresponding product along the product transportation direction.

[0074] Optionally, the visual inspection mechanism includes an image acquisition circuit composed of an industrial camera or a CCD / CMOS sensor, which is a prior art well known to those skilled in the art. In actual use, those skilled in the art can flexibly select a specific visual inspection mechanism as needed. Since the visual inspection mechanism is not the invention point of this case, it will not be described in detail in this case.

[0075] In order to prevent the wired junction box entering the feed conveyor line from being offset and sliding off the side of the feed conveyor line, and to prevent the wired junction box from being too far away from the center of the feed conveyor line and affecting the subsequent clamping and flipping of the wired junction box by the clamping belt group 0, preferably, the product conveyor line also includes a guide plate assembly 8, which is arranged on both sides of the feed conveyor line 6, and each guide plate assembly 8 includes a first guide plate 81 and a second guide plate 82; the first guide plate 81 has an inclined surface, which is connected to one side of the feed conveyor line, and the inclined surface forms an obtuse angle with the plane of the feed conveyor line; the second guide plate 82 is arranged between the first guide plate 81 and the product flipping device, and the second guide plates 82 located on both sides of the feed conveyor line 6 constitute a variable distance channel 821, and the width of the variable distance channel 821 gradually decreases along the product transportation direction.

[0076] In general application scenarios, a wired junction box is grasped by a robot and moved to a feed conveyor line. When the robot grasps the wired junction box and the position is offset, the wired junction box may easily slide off from both sides of the feed conveyor line. In this embodiment, due to the provision of the first guide plate 81, the inclined surface of the first guide plate 81 may be used to guide the wired junction box to slide onto the feed conveyor line.

[0077] It can be understood that the first conveying unit 1 and the second conveying unit 2 will provide a better clamping force for the wired junction box transported from the center line position of the feed conveyor line. Therefore, as a preferred embodiment, the wired junction box on the feed conveyor line should be as close as possible to the center line position of the feed conveyor line.

[0078] Specifically, the second guide plates 82 located on both sides of the feed conveyor line 6 form a variable distance channel 821, the width of which gradually decreases along the product conveying direction, thereby correcting the moving direction of the wired junction box and moving the wired junction box toward the middle.

[0079] In this embodiment, a sensor device 9 is also included. The sensor device 9 is arranged at the gap between the feed conveyor line 6 and the product turning device, and is used to detect whether there is material jamming in the gap between the feed conveyor line 6 and the product turning device. The sensor device 9 is electrically connected to the feed conveyor line; a recovery device is arranged at the feed port of the feed conveyor line 6; when the sensor device 9 detects that there is a product in the gap, the feed conveyor line stops conveying or transports the product in the opposite direction of the product conveying direction until the product enters the recovery device, so as to prevent the wired junction box in the gap from getting jammed when the product turning device is turning.

[0080] The working process of the utility model is as follows:

[0081] The wired junction box is grabbed and enters the feeding and transporting line;

[0082] Before the wired junction box located on the feeding conveyor line enters the product turning device, the visual inspection mechanism takes a photo and determines the orientation of the wired junction box;

[0083] If it is positive, the wired junction box does not need to be turned over, and is directly transported by the first conveying unit 1 or the second conveying unit 2 located below along the product conveying direction to the discharge conveying line;

[0084] If it is the opposite, the wired junction box needs to be flipped, and the first conveying unit 1 and the second conveying unit 2 move towards each other under the action of the clamping device 3 until both conveying units contact the wired junction box, and the wired junction box remains stable and does not slide under the clamping action of the two conveying units, and then flips around a horizontal flip axis driven by the first driving mechanism 4; after flipping, the first conveying unit 1 and the second conveying unit 2 in the clamping state move away from each other, so that one of the first conveying unit 1 or the second conveying unit 2 is separated from the wired junction box, and then the other conveying unit where the wired junction box is located transports the wired junction box to the discharge conveying line, and then the discharge conveying line transfers the wired junction box to the downstream equipment, thus completing the entire working process.

[0085] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
