Description

Technical Field

[0001] The utility model belongs to the technical field of automated machinery, and in particular relates to a multi-station turning device and a turning feeding device. Background Art

[0002] Many products, especially consumer electronics, are currently manufactured using multi-station production lines. During product inspection, different sides of a product often need to be inspected, and the inspection stations are often fixed. Therefore, to inspect multiple sides of a product, the product must be flipped. For example, automated inspection for defects in electronic products often requires inspection of two perpendicular sides. Traditionally, a single station inspects one side first, then flips the machine over to inspect the other side.

[0003] There are three main types of traditional turning devices:

[0004] (1) The advantages of a multi-position rotary turning device are: multiple positions and strong caching capacity; the disadvantages are: low position compatibility and only applicable to smaller products; low turning efficiency and only suitable for products with low processing or testing cycle requirements.

[0005] (2) The flip-plate type turning device has the advantages of fast turning speed and strong compatibility; the disadvantages are that the number of storage spaces is severely limited and it is not convenient to automatically unload materials after turning.

[0006] (3) Mechanical gripper-type flipping device, its advantages are: flexible grasping operation and high flipping accuracy; its disadvantages are: a large number of driving mechanisms, high implementation cost and energy consumption, and the gripper can easily damage the product appearance.

[0007] In order to improve the turnover efficiency, the industry has developed a multi-station turnover device, which mainly sets two product bins on a flip plate to achieve a double-station turnover function. However, in the current multi-station turnover device, the two product bins are arranged horizontally side by side before and after the turnover. When unloading after the turnover, a pushing mechanism is used to push one product and then push the other product out of the bin. Obviously, this method has the risk of material jamming and damage due to collision when unloading products. In addition, in the current method, the two products are unloaded close to each other, which will interfere with the subsequent inspection link. It is often necessary to set up a special separation mechanism on the conveyor line to separate the two products before entering the subsequent processing link (such as the inspection link).

[0008] Furthermore, the dual-station flipping process effectively doubles the efficiency of the product flipping process, requiring the processing capacity of subsequent stations on the traditional assembly line to also be doubled. For example, two inspection stations are required for alternating inspections, and two labeling stations are required for labeling operations. However, having multiple stations with the same function on a single assembly line hinders the timely separation, counting, and tracing of qualified and unqualified products, making confusion more likely. Utility Model Content

[0009] The purpose of this utility model is to provide a multi-station turning device and a turning feeding device, aiming to improve the efficiency of product turning and feeding; this utility model is achieved through the following scheme.

[0010] The first aspect of the present invention provides a multi-station turning device, comprising:

[0011] A flap assembly includes a flap and a flap drive mechanism for driving the flap to switch between a horizontal state and a vertical state, wherein the flap is provided with at least two product bins arranged side by side in the horizontal state and arranged up and down in the vertical state;

[0012] The unloading assembly is arranged at the front side of at least two of the product bins in the longitudinal state, and is controlled to push at least two products in at least two of the product bins backward from the corresponding product bins for unloading.

[0013] The multi-station flipping device provided by the above technical solution has the following beneficial effects: when the flip plate is in a horizontal state, at least two product bins are arranged left and right, and at this time at least two product bins are located at the same height, which is convenient for loading the product bins at the same time (i.e. loading the products into the product bins); when the flip plate is in a vertical state, at least two product bins are arranged up and down, and at this time each product bin is staggered in the vertical direction, which enables at least two products to be unloaded separately at different heights (i.e. pushing the products out of the product bin), which can avoid collision and interference between at least two products.

[0014] As an optimal technical solution, the flap assembly also includes a base plate, one end of the flap is hinged to the top of the base plate through a flap hinge seat; the flap drive mechanism includes a flip cylinder, the cylinder arm of the flip cylinder passes through the base plate and is connected to the flap drive.

[0015] The beneficial effect of the above preferred solution is that by setting a base plate, a working platform of suitable height can be provided for the flip plate, and it is also convenient to set a flip cylinder under the base plate, making the structure of the entire device more reasonable and compact.

[0016] As a preferred technical solution, the unloading assembly includes at least two push rods and a push rod driving mechanism arranged longitudinally, and at least two of the push rods are correspondingly arranged on the front side of at least two product bins arranged longitudinally. The push rod driving mechanism drives at least two of the push rods to synchronously or asynchronously push the products in at least two of the product bins backwards out of the corresponding product bins.

[0017] The beneficial effect of the above preferred solution is that when the flap is in the longitudinal state, at least two product bins are aligned with at least two push rods, and the push rod drive mechanism drives each push rod to push out synchronously or asynchronously for unloading, and the unloading method is flexible and controllable.

[0018] As a preferred technical solution, the push rod drive mechanism includes a push rod slide, a motor, a crank, a crank connecting rod and a push rod connecting piece; at least two push rods are each arranged on the push rod slide to slide laterally and spaced longitudinally from each other; one end of the crank is connected to the drive shaft of the motor, and the other end is rotatably connected to one end of the crank connecting rod; the other end of the crank connecting rod is rotatably connected to the push rod connecting piece; the end of each push rod is fixedly connected to the push rod connecting piece.

[0019] The beneficial effect of the above preferred scheme is that at least two push rods are connected at the same time through a push rod connector, and then driven by a motor, a crank and a crank connecting rod, so that when each push rod slides horizontally relative to the push rod slide, the synchronous pushing action of at least two push rods is achieved.

[0020] As a preferred technical solution, at least two product slots that penetrate the front and back directions are arranged on the left and right sides of the front of the flip plate, and each product slot is provided with a limiting member on one side of the flipping direction; the limiting member includes a product side limiting part and a product top corner wrapping part.

[0021] The beneficial effect of the above-mentioned preferred scheme is that the semi-enclosed structure formed by the product slot and the corresponding limiting parts can effectively limit the inertia generated in the flipping direction during the flipping process of the product, thereby preventing the product from falling off from the product bin; moreover, this semi-enclosed structure saves materials and facilitates the inspection and maintenance of the mechanism.

[0022] As a preferred technical solution, the base plate is provided with a lateral limit buffer for supporting the flap in the lateral state; and / or the base plate is provided with a longitudinal limit buffer for limiting excessive flipping of the flap in the longitudinal state.

[0023] The advantageous effects of the above preferred embodiment are as follows: when the flap is reset to the horizontal position, the transverse limit buffer provided on the base plate can support it, preventing the flap from over-resetting due to inertia. Furthermore, the transverse limit buffer can support the flap in a suitable loading position, facilitating the loading of products into at least two product bins. Furthermore, when the flap is flipped to the vertical position, the longitudinal limit buffer provided on the base plate can limit its lateral position, preventing the flap from over-flipping and thus compromising the accuracy and durability of the device.

[0024] As a preferred technical solution, the multi-station turning device also includes a baffle, which is provided with at least two unloading windows, and the at least two unloading windows are respectively located on the rear side of the corresponding positions of at least two product bins in the longitudinal state.

[0025] The beneficial effect of the above preferred solution is that by setting the baffle and at least two unloading windows on the baffle, it is equivalent to providing interfaces for at least two unloading channels, which makes it easier to unload the at least two products after flipping to different unloading channels in different channels.

[0026] A second aspect of the present invention provides a turning feeding device, comprising:

[0027] The multi-station turning device described above;

[0028] a feeding transmission assembly, arranged in front of at least two product bins of the multi-station flipping device in the horizontal state;

[0029] A loading assembly is configured to control and synchronously push the products on the loading conveying assembly into at least two product bins in the horizontal state in groups of at least two;

[0030] At least two groups of unloading transmission components are respectively arranged on the rear sides of at least two product bins in the longitudinal state, and each group of unloading transmission components carries and transmits a product pushed out of the product bin.

[0031] The flip feeding equipment provided by the above solution can not only realize the flipping of multi-station products, but also unload at least two products separately to the corresponding unloading transmission components for separate unloading. During the unloading process, subsequent processing can be carried out separately; it is very suitable for separate unloading processing after the group products are flipped.

[0032] As a preferred solution, at least two groups of the unloading transmission components have different transmission directions.

[0033] The beneficial effect of the above-mentioned preferred scheme is that the multiple groups of unloading transmission components have different transmission directions, which means that the multiple groups of unloading transmission components do not need to be stacked in the longitudinal direction, so that the multiple groups of unloading transmission components each have better processing operation space when transmitting products, such as facilitating the setting of detection mechanisms, labeling mechanisms, etc. along their respective lines.

[0034] As a preferred solution, each of the unloading transmission components includes a loading platform, an unloading conveyor belt and an unloading pushing piece; the loading platform is arranged on the rear side of the corresponding product warehouse in the longitudinal state, and the unloading pushing piece is controlled to push the product on the loading platform to the unloading conveyor belt.

[0035] The beneficial effect of the above-mentioned preferred scheme is that: by setting up a loading platform and cooperating with a controlled unloading pusher, the rhythm of product unloading to the conveyor belt can be appropriately adjusted; in addition, when an abnormality occurs in the unloading conveyor belt, the loading platform can also temporarily store the products unloaded from the product bin by the unloading component.

[0049] The technical solutions of the embodiments of the present invention are explained and illustrated below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "front", "back" and the like, indicating directions or positional relationships, are all based on the directions or relative positional relationships shown in the drawings, and are intended to facilitate a clear description of the structure of the product or device, and are not intended to limit the actual directions of the product or device during production, use, sales, etc.

[0050] Furthermore, the terms "first" and "second" are used solely for purposes of distinction within the description and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more, unless expressly limited otherwise.

[0051] The specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings. Under the premise that there is no conflict between them, the technical features of each specific embodiment can be used interchangeably.

[0052] The present invention provides a multi-station flipping device 100, using a dual-station configuration as an example, for synchronously flipping two products 200 from a horizontal position to a vertical position, achieving a longitudinally staggered distribution of the two products after flipping 90 degrees. It is understood that similar examples with more stations can be expanded based on the design concept of this embodiment.

[0053] Combine Figures 1 to 6 As shown in FIG. 1 , as a basic embodiment, the multi-station flipping device 100 includes a flap assembly 10 and a discharge assembly 20. The flap assembly 10 includes a flap 11 and a flap driving mechanism 12. The flap driving mechanism 12 drives the flap 11 in a horizontal state (see FIG. 1 ). Figure 1 ) and longitudinal state (see Figure 5 ) between the two product bins; two product bins 13 are provided on the flap 11. The two product bins 13 are arranged left and right of each other in the horizontal state. At this time, the two product bins are at the same height, which facilitates simultaneous loading of the product bins (i.e., loading products into the product bins); the two product bins 13 are arranged above and below each other in the vertical state, which enables the two products 200 to be unloaded separately at different heights (i.e., pushing the products out of the product bins), thereby avoiding collision and interference between the two products during unloading. The unloading assembly 20 is provided on the front side of the two product bins 13 when the flap 11 is in the vertical state. The unloading assembly 20 is controlled to push the two products 200 backwards to the corresponding product bins 13, thereby realizing unloading after the products 200 are flipped.

[0054] Continue to see Figures 1 to 6 The flap assembly 10 also includes a base plate 14. The left end of the flap 11 is hinged above the base plate 14 via a flap hinge seat 111. The flap drive mechanism 12 includes a tilting cylinder 121, a cylinder hinge seat 122, and a cylinder arm hinge seat 123. The cylinder hinge seat 122 is fixedly mounted. The cylinder body of the tilting cylinder 121 is hinged to the cylinder hinge seat 122. The cylinder arm of the tilting cylinder 121 passes through the base plate 14 and is hinged to the back of the flap 11 via the cylinder arm hinge seat 123. The provision of the base plate 14 in this embodiment provides a working platform of suitable height for the flap 11 and facilitates the placement of the tilting cylinder 121 below the base plate 14, making the overall structure of the device more rational and compact.

[0055] See also Figure 1As shown, the unloading assembly 20 includes two longitudinally arranged push rods 21 and a push rod drive mechanism 22. The two push rods 21 are correspondingly positioned in front of the two product bins 13 when arranged longitudinally. The push rod drive mechanism 22 drives the two push rods 21 to synchronously push the two products 200 backward into the corresponding product bins 13. As an alternative embodiment, a push rod drive mechanism can be configured for each push rod 21, with the two push rod drive mechanisms each driving a push rod to synchronously or asynchronously push the two products 200 backward into the corresponding product bins 13. Alternatively, the two driving ends of a push rod drive mechanism can alternately drive the two push rods 21 to move asynchronously, thereby asynchronously pushing the two products 200 backward into the corresponding product bins 13. This allows for flexible and controllable unloading methods.

[0056] See also Figure 1 、 Figure 7 and Figure 8 As shown, as a specific embodiment, the push rod drive mechanism 22 includes a push rod slide 221, a skateboard bracket 222, a motor 223, a motor bracket 224, a crank 225, a crank connecting rod 226 and a push rod connecting member 227; the skateboard bracket 222 is fixedly arranged on the base plate 14, the push rod slide 221 is vertically fixed on the skateboard bracket 222, and the two push rods 21 each slide horizontally and are arranged on the push rod slide 221 with a longitudinal interval between each other; the motor bracket 224 is fixedly arranged on the base plate 14, the motor 223 is fixedly arranged on the motor bracket 224, one end of the crank 225 is connected to the drive shaft of the motor 223, and the other end is rotatably connected to one end of the crank connecting rod 226, and one end of the crank connecting rod 226 is rotatably connected to the middle part of the push rod connecting member 227; the push rod connecting member 227 is arranged longitudinally, and the upper and lower parts are respectively fixedly connected to the ends of the two push rods 21.

[0057] The push rod driving mechanism 22 connects the two push rods 21 simultaneously through the push rod connector 227, and then drives the two push rods 21 through the motor 223, the crank 225 and the crank connecting rod 226, so that when each push rod 21 slides horizontally relative to the push rod slide 221, the two push rods 21 can achieve synchronous pushing action.

[0058] Combine Figure 1 and Figure 2 As shown, the specific structure of the two product bins 13 is as follows: two product slots 131 are provided on the front of the flip plate 11 at intervals on the left and right sides, and the two product slots 131 are through-connected in the front and back directions. In this way, when the flip plate 11 is in the horizontal state, the products 200 can be directly pushed in from the front ends of the two product bins 13; when the flip plate 11 is in the vertical state, the products 200 can also be directly pushed out from the rear ends of the two product bins 13. Each product slot 131 is located on one side of the flip direction (i.e. Figure 1 and Figure 2Limiting members 132 are provided on the left sides of the two product slots 131, respectively. Each limiting member 132 includes a product side limiting portion 1321 and a product corner wrapping portion 1322. The semi-enclosed structure formed by the product slots 131 and the corresponding limiting members 132 effectively limits the inertia generated by the product 200 during the flipping process, thereby preventing the product from falling out of the product bin 13. Furthermore, this semi-enclosed structure saves material and facilitates inspection and maintenance of the mechanism.

[0059] Continue to see Figure 1 and Figure 2 As a preferred embodiment, steel ball rollers 135 are provided on the bottom walls of the two product slots 131. The steel ball rollers 135 can make the friction smaller and smoother when the product 200 is pushed into or out of the product bin 13, and can also effectively protect the product 200 and avoid damage to the appearance of the product 200.

[0060] Continue to see Figures 1 to 6 As a preferred embodiment, the base plate 14 is provided with a transverse limiting buffer 141 that supports the flap 11 in the transverse state. In this way, when the flap 11 is reset to the transverse state, the transverse limiting buffer 141 provided on the base plate 14 can support it, preventing the flap 11 from excessively resetting due to inertia. Moreover, the transverse limiting buffer 141 can support the flap 11 in a suitable loading position, facilitating the loading of products into at least two product bins. In addition, the base plate 14 is also provided with a longitudinal limiting buffer 142 that limits the flap 11 from excessively flipping in the longitudinal state. In this way, when the flap 11 flips to the longitudinal state, the longitudinal limiting buffer 142 provided on the base plate 14 can limit it laterally, preventing the flap 11 from excessively flipping and thus reducing the accuracy and durability of the device.

[0061] Continue to see Figures 1 to 6 As a preferred embodiment, the multi-station flipping device 100 further includes a baffle 30 having two discharge windows 31 formed therein. The two discharge windows 31 are located behind the corresponding positions of the two product bins 13 in the longitudinal position. The provision of the baffle 30 and the two discharge windows 31 in this preferred embodiment provides interfaces for two discharge channels, facilitating the unloading of the two 200 products into different discharge channels after flipping.

[0062] See also Figures 9 to 13 The specific embodiment of the present invention also provides a flip feeding device, including: the multi-station flip device 100 mentioned above, the loading transmission component 300, the loading component 400, the first unloading transmission component 500 and the second unloading transmission component 600.

[0063] The loading transmission component 300 is arranged at the front side of the two product warehouses when the multi-station turning device 100 is in the horizontal state; the loading transmission component 300 is a conveyor belt that drives from right to left, and is used to transport the products 200 one by one; the loading component 400 is controlled to push the products on the loading transmission component 300 into the two product warehouses 13 in the horizontal state in groups of two; the first unloading transmission component 500 and the second unloading transmission component 600 are respectively arranged at the rear side of the two product warehouses 13 in the longitudinal state, and each group of unloading transmission components carries and transmits the products pushed out of a product warehouse 13.

[0064] While achieving the flipping of dual-station products, the above-mentioned flip feeding equipment can also unload the two products separately onto the corresponding unloading transmission components for separate unloading. During the unloading process, each product can undergo subsequent processing. The above-mentioned flip feeding equipment is very suitable for the separate unloading of grouped products after flipping. For example, the products transmitted by the loading transmission component 300 are grouped in pairs, and each two products have similar appearances, but the subsequent processing procedures are different. Suppose product A requires electrical testing after flipping, while product B requires appearance testing after flipping. In this application scenario, the flip feeding equipment provided by the above solution will demonstrate very high flipping efficiency and sorting and unloading efficiency.

[0065] See also Figures 9 to 13 In this embodiment, the first unloading conveyor assembly 500 and the second unloading conveyor assembly 600 have different conveying directions. Specifically, the first unloading conveyor assembly 500 is used to convey unloaded products from right to left, while the second unloading conveyor assembly 600 is used to convey unloaded products from left to right. The different conveying directions of the two unloading conveyor assemblies eliminate the need for stacking them vertically. This allows each unloading conveyor assembly to have more space for processing operations while conveying products, facilitating, for example, the installation of inspection and labeling equipment along their respective conveyor lines.

[0066] Specifically, the first unloading transmission component 500 includes a first loading platform 501, a first conveyor belt 502 and a first unloading pushing member 503; the first loading platform 501 is arranged on the rear side of the upper product warehouse of the two product warehouses 13 in the longitudinal state, and the first conveyor belt 502 and the first unloading pushing member 503 are respectively arranged on the left and right sides of the first loading platform 501; the first unloading pushing member 503 is controlled to push the product 200 on the first loading platform 501 to the first conveyor belt for downstream transmission.

[0067] Similarly, the second unloading transmission component 600 includes a second loading platform 601, a second conveyor belt 602 and a second unloading pushing member (blocked in the figure and not shown); the second loading platform 601 is arranged on the rear side of the lower product warehouse of the two product warehouses 13 in the longitudinal state, and the second conveyor belt 602 and the second unloading pushing member are respectively arranged on the left and right sides of the second loading platform 601; the second unloading pushing member is controlled to push the products on the second loading platform 601 to the second conveyor belt 602 for downstream transmission.

[0068] In the above-mentioned first unloading transmission component 500 and second unloading transmission component 600, by setting a loading platform and cooperating with corresponding unloading pushing parts, the rhythm of unloading products onto the corresponding conveyor belt can be appropriately adjusted; moreover, when an abnormality occurs in the unloading conveyor belt, the loading platform can also temporarily store the products unloaded from the product warehouse 13 by the unloading component 20.

[0069] See also Figure 9 and Figure 10 As shown, the loading assembly 400 includes a horizontally arranged loading pusher 401 and a loading drive mechanism 402. When the loading pusher 401 is set at the front side of the two product bins in the horizontal state, its horizontal span can just push two products at a time; the loading drive mechanism 402 drives the loading pusher 401 to move back and forth, thereby pushing each two products into the two product bins 13 synchronously as a group for flipping operation.

[0070] The above disclosure is only a preferred embodiment of the present application, and certainly cannot be used to limit the scope of rights of the first application. Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
