Description

Technical Field

[0001] The present application relates to the loading of accessories when installing accessories on equipment on a production line, and more specifically, to an improved loading device and loading system for conveying accessories, which can improve the safety, accuracy and operating efficiency of accessory loading. Background Art

[0002] In existing industrial application scenarios, when installing accessories (such as terminal box covers for motors) on equipment (such as motors) on a production line, all types of box covers are usually stacked separately on a material table, and operators select and install them according to different motor models. This box cover loading method has the following disadvantages: 1) A large number of box covers are placed together, and operators need to move frequently to pick up the box covers and install them on the motors, which makes the box cover materials easily knocked over by operators, posing a safety risk; 2) Since the types of box covers are diverse but similar in appearance, operators are prone to picking up the wrong box covers, causing quality accidents; 3) The assembly line of the equipment is heavy. In order to install the box covers, operators may need to frequently pick up the box covers more than 400 times in a single operating day, which increases the labor burden and wastes labor costs. Currently, the following solutions are usually adopted to address these shortcomings: 1) Set up safety fences around the material table to prevent operators from colliding with the box cover, but this increases the time cost of operators to detour when taking the box cover; 2) Each motor to be installed is marked with the motor model, and the operator needs to check the type of box cover and the motor model before installing the box cover, but manual verification still cannot completely avoid the situation where the box cover is installed incorrectly; 3) Set up quality inspectors at the end of the production line to check the quality of the box covers of motors leaving the factory, and manually repair motors with incorrectly installed box covers, but this will further waste a lot of manpower costs.

[0003] In view of this, it is desired to provide an improved box cover feeding method, which can improve the safety and accuracy of box cover feeding in the process of conveying box covers to equipment on the production line, and improve the overall operating efficiency. Utility Model Content

[0071] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0072] In the present application, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present application.

[0073] The purpose of the present application is to provide an improved feeding device and a feeding system including the same, which can improve the safety, accuracy and operating efficiency of loading accessories during the process of conveying accessories to be installed to equipment on a production line.

[0074] In view of this, the present application provides a loading device, which is used to deliver accessories to be installed to equipment on a production line, where the accessories to be installed belong to the same category and have at least one specification. Figure 1 is a schematic diagram of the structure of the feeding device according to an embodiment of the present application at a first top-down oblique angle, Figure 22 is a schematic diagram of the structure of the feeding device and the feeding system according to the embodiment of the present application at a second top view angle. Figure 1 and Figure 2 As shown, the loading device 100 includes: a material platform 110, which includes a carrying plate 111, and the carrying plate 111 can rotate around the central axis of the carrying plate 111; a plurality of material frames 120, which are arranged on the carrying plate around the central axis of the carrying plate 111, each material frame 120 is used to store a plurality of stacked accessories 210 of the same specification, and each material frame 120 is arranged with a label 140 on the surface facing the central axis of the carrying plate 111, and the label 140 on at least one material frame 120 matches the model of the equipment on the production line; a label reading element 130, which is arranged above the carrying plate 111, between the central axis of the carrying plate 111 and the plurality of material frames 120 and facing the outside of the carrying plate 111, the label reading element 130 is located at a first fixed position on a plane parallel to the carrying plate 111, and the label reading element 130 is flush with the label 140 on the material frame 120 in a direction perpendicular to the carrying plate 111 (i.e., located at the same height).

[0075] In this way, the plurality of material frames 120 on the carrier plate 111 can be rotated by rotating the carrier plate 111. When the plurality of material frames 120 rotate, the label reading element 130 can detect the label 140 on the material frame 120 that rotates to the front thereof, and the rotation of the carrier plate 111 can be stopped when the label reading element 130 detects the label 140 that matches the model of the device. In this way, it can be ensured that the accessories 210 in the material frame 120 that stops in front of the label reading element 130 are the accessories to be installed on the device, thereby ensuring the accuracy of loading.

[0076] In addition, by rotating the carrier plate 111 to select the correct accessories, the operator or robot only needs to be located at the predetermined operating position in front of the label reading element 130 to easily pick up the accessories to be installed in the material frame 120 parked in front of the label reading element 130, without the need for personnel to walk or machinery to move to select accessories, thereby ensuring the safety of loading, reducing the burden of personnel or machinery operations, and improving the overall loading operation efficiency.

[0077] In the exemplary embodiment of the present application, the equipment on the production line may be a motor, and the accessory to be installed may be a terminal box cover of the motor to be installed. However, the examples of equipment and accessories are not limited thereto, and the above-mentioned loading device may be applied as long as the accessories can be stored in a stacked manner in the material frame.

[0078] In an exemplary embodiment of the present application, the tag matches the model of the equipment on the production line, which means that the tag records the model information of the equipment or records the model or specification information of the accessory 210 to be installed on the equipment. The tag reading element 130 can read the information recorded on the tag 140 and can compare the read information with the pre-stored model information of the equipment to confirm whether the two match. The tag 140 can be an RFID tag (i.e., an RFID chip), a barcode, or a two-dimensional code, etc., which can record information. Accordingly, the tag reading element 130 can be a reader that can read the corresponding RFID tag, barcode, or two-dimensional code, etc.

[0079] In an exemplary embodiment of the present application, the carrying plate 111 may be circular or approximately circular so as to rotate around its central axis.

[0080] Further, in the present application, the specification of the accessory 210 may include at least one of the size, material, color, and weight of the accessory 210 . Figure 2 The schematic diagram of the structure of the feeding device and the feeding system according to the embodiment of the present application is shown, wherein some accessories 210 are stacked in each material frame 120. The specifications of the accessories 210 stacked in each material frame 120 are the same. However, the specifications of the accessories 210 stacked in different material frames 120 can be the same or different. Figure 2 The assemblies 210 in different frames 120 are shown to have similar shapes (eg, rectangular), but the dimensions (eg, length and / or width) of the assemblies 210 in some frames 120 are different.

[0081] Figure 3 is a schematic diagram of the structure of the feeding device according to an embodiment of the present application from a top view, Figure 4 is a schematic diagram of the structure of the feeding device and the feeding system according to an embodiment of the present application at an upward and oblique viewing angle, and Figure 5 It is a schematic diagram of the structure of a feeding device and a feeding system according to an embodiment of the present application at a side view angle.

[0082] Further, in the embodiments of the present application, Figure 1 and Figure 3 As shown, the bottom of each material frame 120 may be provided with a first opening 1210. The first opening 1210 may be located at the center of the bottom of the material frame 120. Figure 4 As shown, a second opening 1110 matching the first opening 1210 may be correspondingly provided at the arrangement position of each material frame 120 on the carrier plate 111. The first opening 1210 and the second opening 1110 are, for example, circular or rectangular.

[0083] At this time, the material platform 110 may further include a base 113 and a lifting element 115 located below the carrying plate 111. Figure 4 and Figure 5 As shown. The lifting element 115 is installed at a second fixed position on the base 113. The second fixed position can be referred to as a lifting position where the lifting element 115 is used to lift the accessory 210. The lifting element 115 can be cylindrical and can include a movable top that can move up and down within a predetermined range. The top surface of the top can be flat.

[0084] Thus, when any material frame 120 among the multiple material frames 120 rotates to above the second fixed position (i.e., the first opening 1210 at the bottom of any material frame 120 and the second opening 1110 of the supporting plate 111 thereunder rotate to above the second fixed position), the lifting element 115 (or the movable top of the lifting element 115) can move up and down through the first opening 1210 of the material frame 120 and the second opening 1110 below the first opening 1210. Figure 3 The figure shows a case where a material frame 120 is rotated to above the second fixed position. At this time, the top of the lifting element 115 can be seen through the first opening 1210 of the material frame 120. At this time, if the top of the lifting element 115 moves upward, the accessories 210 in the material frame 120 can be lifted upward through the first opening 1210 of the material frame 120 and the second opening 1110 below it. The lifted accessories 210 are more convenient for operators or manipulators to grab.

[0085] In the present application, the sizes of the first opening 1210 and the second opening 1110 can be the same or different, as long as their sizes are both larger than the radial size of the lifting element 115. In addition, the sizes of the first openings 1210 on different material frames 120 can also be the same or different, as long as their sizes are both larger than the radial size of the lifting element 115.

[0086] In addition, in the present application, the lifting element 115 can be a servo electric cylinder, a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc., to lift the accessories 210 in the material frame 120 above it upward. As an example, Figure 4 and Figure 5 It is shown that the lifting element 115 is a servo cylinder.

[0087] Further, if Figure 3 As shown, in the plane parallel to the carrier plate 111 and along the circumferential direction of the carrier plate 111, the distance S1 between the second fixed position and the first fixed position is equal to or substantially equal to the distance between the label on each material frame and the first opening. Therefore, when any material frame 120 rotates to above the second fixed position, the label 140 on the material frame 120 is just located in front of or directly in front of the label reading element 130 in the radial direction. Specifically, the label 140 is located in the reading area of ​​the label reading element 130, so that the label reading element 130 can detect the label 140 on the material frame 120.

[0088] Further, in the present application, the material frame 120 has a rectangular parallelepiped or a shape similar to a rectangular parallelepiped. Figures 1 to 5 As shown, each material frame 120 includes a bottom plate 121 and a first L-shaped plate 123 and a second L-shaped plate 125 fixed on the bottom plate. The bottom plate 121 can be fixed to the carrier plate 111 via a latch 127. Thus, the material frame 120 is detachable and thus replaceable. Figures 1 to 3 1 shows that the bottom plate 121 is fixed to the carrier plate 111 below via the sockets provided on the two sides and the pins 127 inserted into the sockets. However, the present application is not limited thereto, and the bottom plate 121 may also be fixed to the carrier plate 111 via the sockets provided on one, three or four sides and the corresponding pins. In addition, the first opening 1210 may be provided on the bottom plate 121, for example, at the center of the bottom plate 121. In addition, a handle may be installed on the first L-shaped plate 123 and / or the second L-shaped plate 125, so that it is easy for the operator to replace the material frame 120.

[0089] The first L-shaped plate 123 and the second L-shaped plate 125 may be arranged in a diagonal form, for example, along two diagonal corners of a rectangle. The first L-shaped plate 123 may include a first side plate 1231 arranged along the circumferential direction of the carrier plate 111, and a second side plate 1233 extending outwardly from one end of the first side plate 1231 along the radial direction of the carrier plate 111. The second L-shaped plate 125 may include a third side plate 1251 arranged along the circumferential direction of the carrier plate 111, and a fourth side plate 1253 extending inwardly from one end of the third side plate 1251 along the radial direction of the carrier plate 111.

[0090] In addition, the label 140 on the material frame 120 may be arranged on the first side plate 1231 , for example, near the second side plate 1233 . In other words, along the circumferential direction of the carrier plate 111 , the label 140 may be located between the first opening 1210 and the second side plate 1233 .

[0091] It should be noted that the first side plate 1231 and the fourth side plate 1253 may be connected or not connected, and the second side plate 1233 and the third side plate 1251 may be connected or not connected. When they are not connected, the first L-shaped plate 123 and the second L-shaped plate 125 can still define a rectangular shape, and it is easier to take and place the accessory 210.

[0092] In addition, for each material frame 120, the distance between the first L-shaped plate 123 and the second L-shaped plate 125 of the material frame 120 matches the size of the accessories 210 stored in the material frame 120. Specifically, the distance between the first side plate 1231 and the third side plate 1251 defines the maximum size of the accessories 210 that the material frame 120 can accommodate along the radial direction of the carrier plate 111, and the distance between the second side plate 1233 and the fourth side plate 1253 defines the maximum size of the accessories 210 that the material frame 120 can accommodate along the circumferential direction of the carrier plate 111. In particular, in order to stably accommodate the accessories 210, the distance between the first L-shaped plate 123 and the second L-shaped plate 125 of the material frame 120 can be pre-set to be slightly larger than the size of the accessories 210 to be accommodated. In addition, material frames of various sizes can be pre-set to match the accessories 210 of various sizes that may exist, respectively.

[0093] At this time, in the case that the accessories 210 to be transported have various sizes, a material frame 120 with a size matching the size of each accessory 210 to be transported can be selected.

[0094] Further, if Figures 1 to 3 As shown, the feeding device 100 according to the present application may further include at least one presence detection element 150. The at least one presence detection element 150 may be arranged above the carrier plate 111, between the central axis of the carrier plate 111 and the plurality of material frames 120, and toward the outside of the carrier plate 111. On a plane parallel to the carrier plate 111, the at least one presence detection element 150 may be located at a third fixed position. In a direction perpendicular to the carrier plate 111, the at least one presence detection element 150 may be located at at least one predetermined height, respectively, and may be configured to detect whether an accessory 210 exists at the at least one predetermined height.

[0095] In order to accurately detect whether there is an accessory 210 at a predetermined height in the material frame 120, as shown in FIG. Figure 3 As shown, on a plane parallel to the carrier plate 111 and along the circumferential direction of the carrier plate 111, the second fixed position can be located between the first fixed position and the third fixed position, and the distance S2 between the first fixed position and the third fixed position can be greater than the distance between the label 140 on each material frame 120 and the first opening 1210, and less than the distance between the label 140 on each material frame 120 and the fourth side plate 1253 of the second L-shaped plate 125.

[0096] Thus, when any material frame 120 rotates to above the second fixed position, at least one existence detection element 150 is exactly located between the first opening 1210 on the material frame 120 and the fourth side plate 1253. Therefore, each of the at least one existence detection element 150 can accurately detect whether the accessory 210 exists at the predetermined height where the existence detection element 150 is located in the material frame 120, without being affected by the top lifted by the lifting element 115 or the fourth side plate 1253. At this time, the width of the first side plate 1231 should be smaller than the distance from the second side plate 1233 to the existence detection element 150 to avoid interfering with the detection of the existence detection element 150.

[0097] In the present application, to detect the presence or absence of the accessory 210, the presence detection element 150 may be an optical sensor, such as a photoelectric sensor or a laser sensor, or a proximity sensor.

[0098] In the present application, at least one existence detection element 150 may include only one existence detection element 150. In this case, the height of the existence detection element 150 may be flush with the lowest position or the highest position of the accessory 210 after being lifted by the lifting element 115. When the height of the existence detection element 150 is flush with the highest position of the accessory 210 after being lifted, the existence detection element 150 may detect whether the accessory 210 is lifted to the grasping position. For example, if the existence detection element 150 detects that the accessory 210 exists at the height, it means that the accessory 210 has been lifted to the grasping position, and the operator or the manipulator may start to grasp the accessory 210. When the height of the existence detection element 150 is flush with the lowest position of the accessory 210 after being lifted, the existence detection element 150 may detect whether the lifted accessory 210 has been completely grasped. For example, if the existence detection element 150 detects that the accessory 210 does not exist at the height, it means that the lifted accessory 210 has been completely grasped.

[0099] In addition, in the present application, the at least one existence detection element 150 may also include a plurality of existence detection elements 150, such as two, three or more existence detection elements 150. When two existence detection elements 150 are provided, the heights of the two existence detection elements 150 may be flush with the lowest position and the highest position of the raised accessory 210, respectively. Figures 1 to 3 When there are more than one existence detection element 150, the heights of the two existence detection elements 150 can be flush with the lowest position and the highest position of the lifted accessory 210, respectively, and the height of the remaining existence detection element 150 can be located between the two existence detection elements 150 for redundant detection. Figures 1 to 3As shown, in the case of three existence detection elements 150 , it can be considered that the lifted accessory 210 has been grasped only when none of the three existence detection elements 150 detects the existence of the accessory 210 .

[0100] In addition, in the present application, in order to fix the tag reading element 130 and the presence detection element 150, a fixed bracket can also be installed on the base 113 of the material platform 110, and the bracket can include a beam 117 above the carrying plate 111 and across the carrying plate 111, such as Figures 1 to 5 The crossbeam 117 may be fixed with a first arm 1171 parallel to the supporting plate 111 .

[0101] The end of the first arm 1171 may be connected to the first branch 1173 and the second branch 1175, both of which are perpendicular to the carrier plate 111. The tag reading element 130 may be mounted on the first branch 1173 and flush with the tag 140. At least one presence detecting element 150 may be mounted at at least one predetermined height on the second branch 1175. Further, the end of the first arm 1171 may be connected to the first branch 1173 via an L-shaped branch.

[0102] On a plane parallel to the carrier plate and along the circumferential direction of the carrier plate, the distance between the first branch 1173 and the second branch 1175 can be greater than the distance between the label 140 on the material frame 120 and the first opening 1210, and less than the distance between the label 140 on the material frame and the fourth side plate 1253 of the second L-shaped plate 125. Thus, it can be achieved that the distance between the first fixed position and the third fixed position is greater than the distance between the label 140 on each material frame 120 and the first opening 1210, and less than the distance between the label on each material frame 120 and the fourth side plate 1253 of the second L-shaped plate 125.

[0103] Furthermore, in the present application, the material platform 110 may also include a rotating mechanism 119. Figure 4 and Figure 5 As shown, the rotating mechanism 119 can be mounted on the base 113, for example, at the center of the base 113. In addition, the carrier plate 111 can be fixed on the rotating shaft of the rotating mechanism 119, and the central axis of the carrier plate 111 coincides with the rotating shaft of the rotating mechanism 119. In this way, the rotating mechanism 119 can drive the carrier plate 111 to rotate around its central axis. Figure 1 and Figure 4 As shown, a hole for passing the rotating shaft of the rotating mechanism 119 may be provided at the center of the carrying plate 111 , and the rotating shaft passes through the hole and is fixed to the carrying plate 111 .

[0104] Further, in the present application, the loading device 100 may further include a tag reading and writing element 160. The tag reading and writing element 160 is arranged above the carrier plate 111, between the central axis of the carrier plate 111 and the plurality of material frames 120, and toward the outside of the carrier plate 111. On a plane parallel to the carrier plate 111, the tag reading and writing element 160 may be located at a fourth fixed position, and in a direction perpendicular to the carrier plate 111, the tag reading and writing element 160 may be flush with the tag 140 on the material frame 120.

[0105] The tag reading and writing element 160 is a different element from the tag reading element 130. The tag reading and writing element 160 can not only read tags but also write tags. In this case, the tag reading and writing element 160 can be an RFID reader, and the tag can be an RFID tag. It should be noted that an RFID reader can also be used as the tag reading element 130, in which case only its tag reading function is used.

[0106] By setting the label reading and writing element 160, the information of the label on the material frame 120 can be modified. Therefore, when the model of the equipment on the production line changes, but the material frame 120 is still suitable for the accessories to be installed of the new equipment on the production line, there is no need to replace the label on the material frame 120. Instead, the label reading and writing element 160 can be used to read (copy) the model label of the new equipment on the production line, and then the model information in the model label or the label information matching the model information is written into the label on the material frame 120, thereby reducing the operation burden and improving the work efficiency.

[0107] In addition, in order to set the tag reading and writing element 160, a second arm 1177 parallel to the carrying plate 111 may be fixed to the crossbeam 117 of the material platform 110. The end of the second arm 1177 may be further connected to a third branch 1179 perpendicular to the carrying plate 111, and the tag reading and writing element 160 may be installed on the third branch 1179.

[0108] Furthermore, on a plane parallel to the carrier plate 111 and along the circumferential direction of the carrier plate 111, the distance between the fourth fixed position and the first fixed position may be equal to the distance between two tags 140 on two preset material frames 120 among the multiple material frames 120. Thus, when a tag on a certain material frame rotates to the front of the tag reading element 130, a tag on another material frame may just rotate to the front of the tag reading and writing element 160. Thus, the tag reading and writing element 160 may write tags while the tag reading element 130 reads tags.

[0109] In the present application, the rotating mechanism 119 may be a DC motor, an AC motor, a stepping motor, a servo motor, a cam motor, a hydraulic motor, a pneumatic motor, etc., and the rotating shaft of the rotating mechanism 119 may be an output shaft of these components. Figure 4 and Figure 5 The rotating mechanism 119 is shown as a cam motor.

[0110] In addition, in the present application, a plurality of material frames 120 can be evenly arranged around the center of the carrier plate 111. At this time, the rotating mechanism 119 can be configured to rotate a fixed angle each time, then pause for a few seconds to wait for the comparison result of the tag reading element 130, and rotate the fixed angle again when the comparison result is not matched. The fixed angle can be the angle between the two first openings 1210 on the two adjacent material frames 120 and the line connecting the center of the carrier plate 111. Thus, when the first opening 1210 of a certain material frame 120 is initially located above the second fixed position (at this time, the label of the material frame 120 is located directly in front of the label reading element 130), after the rotating mechanism 119 rotates once, the first opening 1210 of the adjacent material frame 120 will rotate to the second fixed position, so that the label reading element 130 can detect the label on the adjacent material frame 120. Alternatively, the rotating mechanism 119 can also be configured to rotate continuously and stop rotating in response to the label reading element 130 reading a label matching the device.

[0111] Utilizing the structure and composition of the feeding device 100 described above, the feeding device 100 according to the present application can be operated manually or semi-automatically by an operator, or fully automatically by itself to perform the following feeding method of accessories. Assume that at least some of the multiple material frames 120 have pre-stored accessories 210 that match the model of the equipment on the production line, the uppermost surfaces of these accessories 210 are located at a predetermined height, and the labels 140 on these material frames 120 have been pre-written with the equipment model information of the equipment or the model or specification information of the matching accessories 210. The lifting element 115 is configured to lift the accessory 210 by a predetermined distance so that the uppermost surface of the accessory 210 reaches a specified height, and a presence detection element 150 is provided at the specified height. Initially, the model label of the equipment conveyed to the current position on the production line is read by the label reading and writing element 160 or another label reading element on the production line to identify and store the equipment model information. Then, the rotating mechanism 119 can be controlled to rotate. If a material frame 120 is initially located above the second fixed position, the rotating mechanism 119 can rotate a fixed angle each time, which can be the angle between the two first openings 1210 on the two adjacent material frames 120 and the line connecting the center of the carrier plate 111. After the rotating mechanism 119 rotates once, the label reading element 130 can read the label on the material frame rotated in front of it and compare it with the pre-stored device model information. If the comparison result is not matched, the rotating mechanism 119 can be controlled to continue rotating. If the comparison result is matched, the rotating mechanism 119 can be controlled to stop rotating. Then, the lifting element 115 can be controlled to lift the accessory 210 in the current material frame 120 through the first opening 1210 and the second opening 1110 so that the uppermost surface of the accessory 210 reaches the specified height. Next, the detection result of the existence detection element 150 located at the specified height is obtained. When the existence detection element 150 indicates that the accessory 210 exists at the specified height, it is considered that the accessory 210 has been lifted to the grasping position. Afterwards, the lifted parts are manually or automatically grabbed one by one by the operator or by the manipulator and delivered to the equipment on the production line. In the case of three existence detection elements 150, when none of the three existence detection elements 150 detects the existence of the parts 210, it is considered that the parts 210 in the current material frame 120 have been grabbed. At this time, the lifting element 115 is controlled to drop a predetermined distance so that its top is located below the carrier plate 111. Then, the rotating mechanism 119 is controlled to continue to rotate and continue the above-mentioned processing process.

[0112] Further, in the present application, the feeding device 100 may also be provided with a processing unit (not shown) to realize the automatic operation of the feeding device 100. At this time, the processing unit may be connected to the tag reading element 130, the tag reading and writing element 160, the rotating mechanism 119, etc., and may control these components according to a pre-stored algorithm or program so that the feeding device 100 realizes the automatic feeding process of the accessories.

[0113] In addition, the present application also provides a feeding system 200. Figure 2 , Figure 4 and Figure 5 As shown, the loading system 200 includes the loading device 100 described above and a plurality of accessories 210, which are stored in at least one material frame 120 of the plurality of material frames 120 of the loading device 100. The plurality of accessories 210 belong to the same category and have at least one specification, the specifications of the accessories 210 stored in each material frame 120 are the same, and the labels 140 arranged on each material frame 120 indicate the specifications of the accessories 210 stored in the material frame 120.

[0114] Furthermore, the loading system 200 may further include a material frame set, and the multiple material frames 120 arranged on the carrier plate 111 may be selected from the material frame set. The material frame set may include material frames of multiple specifications, and each material frame 120 of the multiple specifications is used to store accessories 210 whose specifications match the material frame 120.
