Abstract
Description
Technical Field
[0001] This disclosure relates to an alternating feeding device, belonging to the field of automation equipment technology. Background Technology
[0002] With the development of technology, more and more factories are adopting automated production lines to manufacture products. In particular, in the manufacturing process of some electronic products, it is necessary to use dispensing machines to apply adhesive to the components of electronic products.
[0003] When a dispensing machine is working, it needs to be fed through a feeding mechanism. Generally, this feeding mechanism has two feeding positions: at one feeding position, the dispensing machine processes electronic products, and at the other feeding position, a robotic arm can move away the finished workpiece and put in the workpiece to be processed, thus realizing the alternating feeding of the dispensing machine.
[0004] However, existing alternating feeding devices generally use a dual-shaft drive carrier to achieve alternating feeding. Because shafts are expensive, this cannot reduce the overall cost of the dispensing machine. Moreover, such feeding devices have multiple drive units, making the operation process complex and inconvenient to control. Utility Model Content

[0062] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.
[0063] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0064] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.
[0065] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.
[0066] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.
[0067] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0068] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0069] Figure 1 This is a schematic diagram of the alternating feeding device according to one embodiment of the present disclosure.
[0070] The alternating feeding device disclosed herein can realize the alternating feeding of workpieces during use. Specifically, the alternating feeding device disclosed herein may include components such as: a first feeding device 100, a drive device 200, a second feeding device 300, a first transmission device 400, a second transmission device 500, and a frame 600.
[0071] like Figure 1 As shown, the frame 600 of this disclosure may include two parallel side plates 610 and a base 620 connecting the two side plates 610, wherein the lower end of the side plate 610 may be disposed on the upper surface of the base 620. That is to say, the frame 600 of this disclosure can be formed into a concave frame structure.
[0072] The upper end of the side plate 610 may be provided with a first guide rail, wherein the first guide rail is arranged along a first direction, and the two first guide rails are arranged approximately horizontally, thereby enabling the first feeding device 100 of this disclosure to reciprocate on the first guide rail. In other words, the first feeding device 100 of this disclosure can move along the first guide rail in either a first direction or a second direction. Wherein, with Figure 1 The directions shown are as follows: the first direction is a horizontal direction to the left, and the second direction is a horizontal direction to the right.
[0073] Figure 2 This is a schematic diagram of the structure of a first feeding device and a driving device according to an embodiment of the present disclosure.
[0074] like Figure 1 and Figure 2As shown, the drive device 200 of this disclosure is used to drive the first feeding device 100 to move along a first direction; of course, the drive device 200 can also drive the first feeding device 100 to move along a second direction. That is to say, the drive device 200 of this disclosure can drive the first feeding device 100 to reciprocate along the first guide rail.
[0075] In a preferred embodiment, the drive device 200 can be fixed to the side plate 610 of the frame 600, and the drive device 200 can be a cylinder; the cylinder can be a rodless cylinder.
[0076] The first feeding device 100 disclosed herein may include a pallet 110 and a first carrier 120 disposed on the pallet 110; wherein the pallet 110 may be a square plate structure, and a first slider is disposed at each of the four corners of the pallet 110, wherein the first slider is slidably disposed on a first guide rail, thereby enabling the pallet 110 to slide along the first guide rail.
[0077] Figure 3 This is a schematic diagram of the structure of a second feeding device according to one embodiment of the present disclosure.
[0078] like Figure 3 As shown, the base 620 of the frame 600 of this disclosure is further provided with a support plate 630. There are two support plates 630, which are arranged in parallel. Preferably, the support plate 630 is arranged in parallel with the side plate 610, and the two support plates 630 are located between the two side plates 610.
[0079] In a preferred embodiment, the vertical height of the support plate 630 is less than the vertical height of the side plate 610. For example, the vertical height of the support plate 630 can be half the vertical height of the side plate 610. This allows the second feeding device 300 to pass under the first feeding device 100 during movement, thus preventing motion interference between the first feeding device 100 and the second feeding device 300.
[0080] Specifically, such as Figure 3 As shown, the second feeding device 300 of this disclosure includes components such as a base plate 310, a lifting rod 320, and a top plate 330.
[0081] A second guide rail is provided at the upper end of the support plate 630. The second guide rail is positioned approximately horizontally, and two guide rails are provided. These two second guide rails are parallel to each other. Furthermore, the second guide rail is also parallel to the first guide rail. Therefore, the second feeding device 300 of this disclosure can reciprocate on the second guide rail.
[0082] Specifically, the base plate 310 is formed into a roughly square plate structure, wherein four second sliders are provided at the four corners of the base plate 310. The second sliders are slidably disposed on the second guide rail, so that the base plate 310 can slide back and forth on the second guide rail.
[0083] In this disclosure, the base plate 310 has four through holes at its four corners. Four linear bearings can be installed in these four through holes, and four lifting rods 320 are installed in these four linear bearings respectively. Thus, when the lifting rods 320 slide in the linear bearings, they can generate lifting motion.
[0084] The top plate 330 is disposed at the upper end of the lifting rod 320 so that the top plate 330 will move up and down when the lifting rod 320 slides relative to the bottom plate 310. Furthermore, a second carrier 340 may be disposed on the top plate 330.
[0085] Figure 4 This is a schematic diagram of the structure of a first transmission device according to one embodiment of the present disclosure.
[0086] like Figure 4 As shown, the first transmission device 400 of this disclosure can be a belt drive structure, such as a synchronous belt drive structure. Of course, this disclosure is not limited to this; for example, the first transmission device 400 can also be a chain drive structure. The first transmission device 400 of this disclosure will be described below using a synchronous belt drive structure as an example. Furthermore, the synchronous belt drive structure can ensure repeatability and positioning accuracy.
[0087] The first transmission device 400 of this disclosure includes a synchronous belt 410 and pulleys 420; wherein the pulleys 420 are rotatably disposed on the side plate 610, and the synchronous belt 410 is supported by the pulleys 420 and is capable of rotation. In a specific embodiment, there may be multiple pulleys 420, for example, in this disclosure, there may be six pulleys 420. These six pulleys 420 can divide the synchronous belt 410 into an upper part and a lower part, wherein the upper part and the lower part of the synchronous belt 410 are both horizontally disposed. In this case, the first feeding device 100 can be fixed to the upper part of the synchronous belt 410, for example, the support plate 110 of the first feeding device 100 can be fixed to the upper part of the synchronous belt 410. Accordingly, the second feeding device 300 can be fixed to the lower part of the synchronous belt 410. For example, the base plate 310 of the second feeding device 300 can be connected to the lower part of the synchronous belt 410, that is, the base plate 310 is fixedly connected to the annular transmission component (synchronous belt).
[0088] Therefore, the first feeding device 100 and the second feeding device 300 have opposite directions of movement. Specifically, with Figure 1As shown in the direction, when the first feeding device 100 moves to the left, the first feeding device 100 can drive the upper part of the synchronous belt 410 to move to the left. As a result, the lower part of the synchronous belt 410 will move to the right, and drive the second feeding device 300 to move to the right.
[0089] In a similar working process, when the first feeding device 100 moves to the right, the second feeding device 300 will move to the left.
[0090] In other words, in this disclosure, when the first feeding device 100 moves, the first feeding device 100 can drive the second feeding device 300 to move in the opposite direction to the first feeding device via the first transmission device 400. Specifically, when the first feeding device 100 moves along a first direction, the first feeding device 100 drives the second feeding device 300 to move along a second direction via the first transmission device 400; when the first feeding device 100 moves along a second direction, the first feeding device 100 drives the second feeding device 300 to move along the first direction via the first transmission device 400; wherein the first direction is opposite to the second direction.
[0091] Figure 5 This is a schematic diagram of the structure of a guide plate 510 according to one embodiment of the present disclosure.
[0092] like Figure 1 and Figure 5 As shown, when the second feeding device 300 moves along the second direction, the second transmission device 500 is used to drive the second feeding device 300 to first lower and then raise.
[0093] Specifically, the second transmission device 500 disclosed herein may include structures such as a guide plate 510, a connecting rod 520, and a follower 530. In a preferred embodiment, the guide plate 510 is disposed between two support plates 630 and is vertically arranged. A guide groove is provided on the guide plate 510, the opening of which faces the side of the guide plate 510.
[0094] The connecting rod 520 is arranged in a generally vertical manner. Preferably, the upper end of the connecting rod 520 is provided on the top plate 330, and the lower end of the connecting rod 520 is provided with a follower 530. The follower 530 is configured to move along the guide groove so that the follower 530 can drive the top plate 330 to produce a lifting motion.
[0095] like Figure 5As shown, the guide groove of this disclosure may include a first groove segment 511, a second groove segment 512, a third groove segment 513, and a fourth groove segment 514 connected in sequence. The first groove segment 511 and the fourth groove segment 514 are both horizontally arranged. Thus, when the first feeding device 100 is in the first position, the follower 530 is located in the first groove segment 511; when the first feeding device 100 is in the second position, the follower 530 is located in the fourth groove segment 514; wherein, when the first feeding device 100 is in the first position, the feeding device is directly above the fourth groove segment 514; and when the first feeding device 100 is in the second position, the first feeding device 100 is directly above the first groove segment 511.
[0096] The second groove segment 512 and the third groove segment 513 are formed in a V-shape; specifically, with Figure 5 As shown, from left to right, the second trough section 512 slopes downward and the third trough section 513 slopes upward. Therefore, the top plate 330 of the second feeding device 300 of this disclosure can first descend and then rise during its movement to the right. Similarly, the top plate 330 also first descends and then rises during its movement to the left.
[0097] When the first feeding device 100 moves to the middle position between the first position and the second position, the second feeding device 300 is located directly below the first feeding device 100.
[0098] Figure 6 This is a schematic diagram of the structure of a follower according to one embodiment of the present disclosure.
[0099] In a preferred embodiment, such as Figure 6 As shown, the follower 530 is a rolling element disposed at the lower end of the connecting rod 520. Thus, the follower 530 of this disclosure can generate rolling and sliding motions in the guide groove, thereby preventing the follower 530 from getting stuck in the guide groove.
[0100] Based on the above structure, the alternating feeding device disclosed herein uses a single cylinder for power, enabling alternating feeding actions at two workstations. Its control method is simple, hard limit switches ensure positional accuracy, and the cost is significantly lower than that of using two axes, making it a complete replacement for the common dual-axis alternating feeding method. Furthermore, the alternating feeding device disclosed herein occupies little space, operates stably, and is easy to maintain, laying the foundation for adopting this alternative solution in most future equipment.
