[0039] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0040] Next, combine Figure 1-Figure 7Understand the loading device and sheet metal stamping production line of the embodiments of the present application.

[0041] During production, the sheet material 300 to be processed needs to be loaded from the pallet 200 onto the production line (e.g., transported to a stamping station and loaded onto the stamping area of ​​the stamping equipment). Therefore, the sheet material 300 to be processed needs to be grabbed from the pallet 200 for the next step. During the loading process, the position of the pallet 200 usually needs to be adjusted. After the pallet 200 is positioned in a predetermined area, the grabbing equipment is matched to achieve the grabbing of the sheet material 300 to be processed. The positioning process of the pallet 200 often takes a long time.

[0042] Based on this, in order to facilitate positioning of the tray 200 to the area corresponding to the grabbing position, the embodiment of the present application provides a first positioning portion 110 and a second positioning portion 120 for positioning on the loading platform 100 .

[0043] The loading device according to the embodiment of the present application includes a loading platform 100 and a tray 200 .

[0044] The loading platform 100 is movably arranged on the production line; the tray 200 is detachably arranged on the loading platform 100, and the tray 200 is used to place the sheet material 300 to be processed; a first positioning portion 110 and a second positioning portion 120 are provided on the loading platform 100, the first positioning portion 110 is suitable for positioning and cooperating with the tray 200 in the first direction, and the second positioning portion 120 is suitable for positioning and cooperating with the tray 200 in the second direction, and the first direction is orthogonal to the second direction. Among them, the first direction can be parallel to any direction on the loading platform 100, and similarly, the second direction can also be any other direction parallel to the loading platform 100. In addition, the first direction and the second direction in the embodiment of the present application can be set to be orthogonal, or the first direction and the second direction can be set to other intersection angles, for example, an acute angle of 60° is formed between the first direction and the second direction.

[0045] Specifically, after being transported to the loading platform, the pallet 200 first engages with the first positioning portion 110. The first positioning portion 110 restricts the movement of the pallet 200 in the first direction, thereby positioning the pallet 200 in the first direction. After the first positioning portion 110 engages and positions the pallet 200, the pallet 200 still has the freedom to move in the second direction. Therefore, under the action of an external force, the pallet 200 can further move in the second direction. The pallet 200 moves in the second direction to the desired position (i.e., the position where it engages with the second positioning portion 120), thereby achieving engagement between the second positioning portion 120 and the pallet 200, thereby completing positioning in the second direction. At this point, the pallet 200 is positioned relative to the loading platform 100 in both the first and second directions. The aforementioned external force can be any external force, such as a forklift, a manual push on the pallet, or the like.

[0046] According to the loading device of the embodiment of the present application, a first positioning portion 110 and a second positioning portion 120 are constructed on the loading platform 100. In the process of positioning the pallet 200 on the loading platform 110, it is only necessary to cooperate with the first positioning portion 110 and the second positioning portion 120 in sequence to complete the positioning of the pallet 200 relative to the loading platform 100. There is no need to perform complex position adjustments, which greatly simplifies the positioning process and reduces the positioning complexity, thereby reducing the time required to position the pallet 200 on the loading platform 100 and thus improving the production line efficiency.

[0047] According to further embodiments of the present application, continue to refer to Figure 1-Figure 2 The first positioning portion 110 and the second positioning portion 120 will be described.

[0048] First, refer to Figure 1 The loading platform 100 in this example is shown.

[0049] The loading platform 100 is a rectangular platform. Figure 1 The lower plane shown is used to be placed on a loading trolley (not shown in the figure), which supports the loading platform 100 to achieve lifting and transportation. The upper plane of the loading platform 100 is constructed with a first positioning portion 110 and a second positioning portion 120.

[0050] In addition, a plurality of sensor positioning holes 130 are provided through the loading platform 100 in the thickness direction thereof. The sensor positioning holes 130 are used to pass the sensing end of the plate sensor. Specifically, the plate sensor is provided in the loading trolley to detect whether there are any unremoved plates 300 to be processed on the loading platform 100.

[0051] Next, continue to refer to Figure 1 And combined Figure 2 The first positioning portion 110 will be described.

[0052] In some embodiments, there may be multiple first positioning portions 110 provided on the loading platform 100, and the multiple positioning portions are spaced apart along the second direction, suitable for pushing the tray 200 in the first direction to limit the movement of the tray 200 in the first direction.

[0053] Specifically, the first positioning portion 110 can be a protrusion formed on the loading platform 100 and spaced apart along the second direction. The edge of any side of the tray 200 pushes against each first positioning portion 110 to achieve movement along the second direction. More specifically, there are two first positioning portions 110, and each of the first positioning portions 110 is a long plate body provided on the loading platform 100. The length direction of the long plate body extends in a direction perpendicular to the upper surface of the loading platform 100. The two first positioning portions 110 are spaced apart along the second direction. The first direction is perpendicular to the second direction in the upper surface of the loading platform 100. Therefore, the two first positioning portions 110 participate in defining a pushing surface toward one side of the tray 200. The pushing surface is suitable for pushing the tray 200 and limiting the position of the tray 200 in the first direction.

[0054] Can be combined Figure 1-Figure 2 For understanding, for example, the first positioning portion 110 is a long plate, the tray 200 is a rectangular frame, and after one side edge of the tray 200 is pushed to the same side plane of the two long plates, the two long plates contact the side of the tray 200 to define a pushing surface, so that the two first positioning portions 110 limit the movement of the tray 200 in the first direction. Figure 2 As shown in the figure, after the two long plates are pushed against one side edge of the tray 200, the movement of the tray in the first direction is restricted.

[0055] Of course, in other cases, the first positioning portion 110 may be provided as a single portion. For example, the first positioning portion 110 may be provided as a long strip-shaped recess, the length of which is arranged along the second direction, and one or more protrusions are correspondingly provided on the tray 200, and the protrusions on the tray 200 are then embedded in the long strip-shaped recess. In this way, the tray 200 can move along the length direction of the long strip, i.e., the second direction.

[0056] As can be seen, after the pallet 200 is placed on the loading platform 100, the pallet 200 cooperates with the first positioning portion 110 to achieve positioning in the first direction. It is understood that during the placement process, the pallet 200 usually needs to be transferred from a forklift to the loading platform 100. Therefore, during the placement process, the pallet 200 can be directly removed from the forklift and pushed against the first positioning portion 110 to achieve position control. This eliminates the need for a complex positioning process, facilitates operation, and allows for initial positioning of the pallet 200 relative to the loading platform 100.

[0057] Next, continue to refer to Figure 1 The second positioning portion 120 and the matching portion 210 are further described.

[0058] In some embodiments, there are multiple second positioning portions 120, and the tray 200 is provided with a mating portion 210 on a side plane facing the loading platform 100 that mates with the second positioning portion 120. The mating portion 210 and the second positioning portion 120 can be mated using any suitable structure, such as a snap-fit, magnetic, or other structure capable of achieving a position-limiting function. The tray 200 moves under the position-limiting guidance of the first positioning portion 110 until the mating portion 210 in the tray 200 moves to the area where the second positioning portion 120 is located, at which point the first positioning portion 110 and the mating portion 210 form a position-limiting mating relationship.

[0059] Specifically, the second positioning portion 120 can be constructed as a positioning pin, and then a plurality of positioning pins are constructed on the loading platform 100. The plurality of positioning pins include at least two positioning pins spaced apart along one direction, and at least two positioning pins spaced apart along another direction, and the line between the aforementioned two positioning pins and the line between the latter two positioning pins define a positioning surface, and the positioning surface is parallel to the horizontal plane. And the plurality of positioning pins are all coordinated with the pallet to achieve relative position limitation of the pallet in the horizontal direction through the positioning surface. Of course, the plurality of positioning pins can also be spaced apart along the first direction so that the line between the plurality of positioning pins is orthogonal to the setting direction of the first positioning portion 110, thereby defining the positioning surface.

[0060] More specifically, the second positioning portion 120 is constructed as a positioning pin formed on the upper surface of the loading platform 100, and the mating portion 210 is set as a positioning hole 270 that cooperates with the positioning pin. When the tray 200 moves along the second direction to the positioning area, since the positioning pin forms a protrusion on the loading platform 100, the positioning hole 270 cooperates with the protrusion formed by the positioning pin. Under the action of gravity, the positioning pin will cooperate with the positioning hole 270 to complete the positioning.

[0061] It is understood that, after the first positioning portion 110 engages with the tray 200, it restricts the movement of the tray 200 in the first direction. At this point, the tray 200 still has the freedom to move in the second direction within the loading platform 100. When the tray 200 is moved in the second direction by an external force, the engaging portion 210 can move in the second direction to engage with the second positioning portion 120. Once the tray 200 engages with the second positioning portion 120, the push plate 200 is positioned relative to the loading platform 100 in the second direction. Therefore, the positioning process does not require a complex process, simplifying the operation and improving production efficiency.

[0062] Further, refer to Figure 1 And further combine Figure 3It is understood that in different examples, there may be multiple groups of mating portions 210, with multiple groups of second positioning portions 120 spaced apart and arranged opposite to each other in the second direction, and multiple mating portions 210 in each group spaced apart in the first direction. Each group of mating portions 210 mates with a corresponding group of second positioning portions 120 to form a fixed position. In some examples, only one group of second positioning portions 120 may be used to mate with the mating portions 210.

[0063] Exemplarily, six second positioning portions 120 are arranged at intervals along the second direction, and a total of six trays 200 are constructed on a side plane for contacting the loading platform 100 .

[0064] refer to Figure 2 As shown, for better explanation, the six positioning parts are defined here as the first positioning pin 121, the second positioning pin 122, the third positioning pin 123 and the fourth positioning pin 124, respectively. There are two second positioning pins 122 and two third positioning pins 123, and the two second positioning pins 122 are spaced apart along the first direction, and the two third positioning pins 123 are also spaced apart along the first direction.

[0065] Two second positioning pins 122 form a group, and two third positioning pins 123 form a group.

[0066] The first positioning pin 121 is connected to the fourth positioning pin 124 to form a first connecting line. One of the second positioning pins 122 is located on the first connecting line, and one of the third positioning pins 123 is also located on the first connecting line. Another second sub-positioning pin is connected to the third positioning pin 123 to form a second connecting line. The first connecting line and the second connecting line are both arranged along the second direction, and are separated by a first spacing distance.

[0067] refer to Figure 3 As shown, for better explanation, the six mating portions 210 are defined as a first pin hole 211, a second pin hole 212, a third pin hole 213, and a fourth pin hole 214. There are two first pin holes 211 and two fourth pin holes 214, and the two first pin holes 211 are arranged along the first direction, and the two fourth pin holes 214 are also arranged along the first direction.

[0068] The two first pin holes 211 constitute one group, and the two fourth pin holes 214 constitute one group.

[0069] Among them, after the tray 200 contacts the first positioning portion 110 to achieve positioning in the first direction, one of the two first pin holes 211 is on the first connecting line, and the other is on the second connecting line; one of the two fourth pin holes 214 is on the first connecting line, and the other is on the second connecting line.

[0070] Furthermore, the first pin hole 211 is used to adapt to the first positioning pin 121 , the second pin hole 212 is used to adapt to the second positioning pin 122 , the third pin hole 213 is used to adapt to the third positioning pin 123 , and the fourth pin hole 214 is used to adapt to the fourth positioning pin 124 .

[0071] Next, the assembly correspondence between the second positioning portion 120 and the matching portion 210 is described in conjunction with a specific situation. Figure 2 As shown, the loading platform 100 is configured with two sets of second positioning portions 120, in other words, the loading platform 100 is configured with two second positioning pins 122 and two third positioning pins 123. Multiple sets of second positioning portions 120 can be matched with corresponding matching portions 210 respectively.

[0072] For example, when the tray 200 is configured with a second pin hole 212 and a third pin hole 213, the user can select, based on the positions of the second pin hole 212 and the third pin hole 213, one of the two second positioning pins 122 and one of the two third positioning pins 123 to mate with the second pin hole 212 and the third pin hole 213, respectively. By switching between different mate modes, various positioning situations can be accommodated.

[0073] For another example, the tray 200 is configured with two second pin holes 212 and two third pin holes 213 . The two second pin holes 212 are adapted to the two second positioning pins 122 , and the two third pin holes 213 are adapted to the two third positioning portions.

[0074] It can be understood that since the two second positioning portions 120 in the same group and the two matching portions 210 in the same group are both arranged along the first direction, after the second positioning portions 120 and the matching portions 210 are positioned, they can form limitation in both the first direction and the second direction.

[0075] Next reference Figure 4-Figure 7 The tray 200 in the embodiment of the present application is described.

[0076] In some cases, the sheet material 300 to be processed needs to be transported by a forklift or a transport vehicle before being transported to the loading platform 100. During the transportation process, due to the lack of fixation of the sheet material 300 to be processed, the overlapping sheet materials 300 to be processed may move and deviate from the initial position during transportation. For this reason, the pallet 200 in some embodiments also includes a positioning plate 260.

[0077] For details, please refer to Figure 4 Combine Figure 5-6To understand, the tray 200 includes a first plate 220 and a second plate 230. The first plate 220 is positioned and matched with the loading platform 100. Specifically, the edge of the first plate 220 along the first direction pushes against the first positioning portion 110 to form a limit. The bottom surface of the first plate 220 is configured with a matching portion 210 that matches the second positioning portion 120. The first plate 220 and the second plate 230 are integrally connected.

[0078] Combine Figure 3 As shown, it can be understood that the first plate body 220 and the second plate body 230 are integrally connected to form a planar plate structure, and the plane formed by the first plate body 220 and the second plate body 230 is used to place the sheet material 300 to be processed. In different situations, an area for placing the sheet material 300 to be processed can be defined on the first plate body 220, or an area for placing the sheet material 300 to be processed can be defined on the common plane of the first plate body 220 and the second plate body 230.

[0079] Furthermore, positioning holes 270 are provided on both the first plate 220 and the second plate 230. Positioning plates 260 are detachably mounted in the positioning holes 270 and serve to position the sheet material 300 to be processed. The positioning holes 270 are arranged around the placement area. When the positioning plates 260 are mounted in the positioning holes 270, they contact the sheet material 300 to be processed and position the sheet material 300 to be processed. The positioning holes 270 can be located on one or more sides of the placement area.

[0080] For example, positioning holes 270 are constructed around the placement area to achieve the purpose of limiting the position of the plate 300 to be processed from four directions by the positioning plate 260.

[0081] For example, Figure 3 As shown, positioning holes 270 are constructed in three directions around the placement area, and positioning plates 260 are arranged in three directions to limit the sheet material 300 to be processed in the placement area.

[0082] It is understandable that by resisting the sheet material 300 to be processed in one or more directions to form a limit, it is possible to prevent the sheet material 300 to be processed from moving during transportation, thereby causing the sheet material 300 to deviate from the original position or even fall.

[0083] In a further embodiment, there are multiple groups of positioning holes 270, each group of positioning holes 270 is suitable for assembling a positioning plate 260 to adapt to different specifications of the sheet materials 300 to be processed, and multiple positioning holes 270 are formed in the first direction and the second direction.

[0084] Specific reference Figure 4-Figure 6As shown, multiple groups of positioning holes 270 are constructed in the first direction and the second direction, which can adjust the distance between the positioning plate 260 and the placement area in the corresponding direction, thereby changing the size of the limiting space formed by the positioning plate 260 on the placement area.

[0085] In combination with the drawings, the first plate body 220 and the second plate body 230 are both rectangular frame structures. The first plate body 220 is provided with a plurality of groups of positioning holes 270 spaced apart along the first direction to constitute a plurality of groups of positioning holes 270 arranged along the first direction. The second plate body 230 is provided with a plurality of groups of positioning holes 270 spaced apart along the second direction to constitute a plurality of groups of positioning holes 270 arranged along the second direction.

[0086] Next, continue to combine the diagram Figure 4-Figure 6 An exemplary case of providing the positioning hole 270 and the positioning plate 260 will be described.

[0087] refer to Figure 4 As shown, there are five positioning plates 260 arranged around the placement area. For better explanation, the five positioning plates 260 are respectively defined as a first positioning plate 261, a second positioning plate 262, a third positioning plate 263, a fourth positioning plate 264, and a fifth positioning plate 265.

[0088] The first positioning plate 261 and the fifth positioning plate 265 are arranged opposite each other in the second direction, and the relative plane between them forms an area for placing the to-be-processed sheet material 300. Accordingly, the first positioning plate 261 and the fifth positioning plate 265 are fixed to the positioning holes 270 configured along the second direction on the first plate body 220. The positioning holes 270 on the second plate body 230 may include multiple groups, so that the first positioning plate 261 and the fifth positioning plate 265 can be fixed to different groups of positioning holes 270 to adjust the fixed position.

[0089] The second positioning plate 262, the third positioning plate 263, and the fourth positioning plate 264 are arranged on the same side of the placement area to limit the movement of the workpiece 300 in the first direction. Accordingly, the second positioning plate 262, the third positioning plate 263, and the fourth positioning plate 264 are fixed to the positioning holes 270 configured along the first direction on the first plate body 220. The positioning holes 270 on the first plate body 220 can include multiple groups, so that the second positioning plate 262, the third positioning plate 263, and the fourth positioning plate 264 can be fixed to different groups of positioning holes 270 to adjust the fixed position.

[0090] Further integration Figure 7 It is understood that the first positioning plate 261 and the fifth positioning plate 265 can be selectively assembled into different positioning holes 270 on the second plate 230. For example, Figure 7In the two situations corresponding to the dashed lines and the solid lines shown in the figure, the first positioning plate 261 and the fifth positioning plate 265 switch between the first position a depicted by the dashed lines and the second position b depicted by the solid lines, thereby adjusting the position of the positioning plate 260 and changing the distance between the first positioning plate 261 and the fifth positioning plate 265 to adapt to different sizes of the sheet materials 300 to be processed. The third positioning plate 263, the fourth positioning plate 264 and the fifth positioning plate 265 also switch between the second position c depicted by the dashed lines and the fourth position d depicted by the solid lines to change the limiting space of the sheet material 300 to be processed, thereby adapting to different sizes of sheets.

[0091] In some embodiments, the assembly between the positioning plate 260 and the positioning hole 270 is achieved through a spring pin. When switching the positioning hole 270 used to assemble the positioning plate 260, it is only necessary to press or pull up the spring pin to achieve the separation between the positioning plate 260 and the positioning hole 270 to adjust the assembly position of the positioning plate 260.

[0092] Further, continue to refer to Figure 4-Figure 5 It is understood that the tray 200 is further configured with a first sliding assembly 240 disposed along the first direction and a second sliding assembly 250 disposed along the second direction.

[0093] The first sliding assembly 240 is connected to the tray 200 and a set of positioning plates 260 that move along a first direction. The first sliding assembly 240 can be any component or mechanism capable of sliding transmission, such as a screw drive assembly or a slide rail drive assembly. The second sliding assembly 250 is connected to the tray 200 and a set of positioning plates 260 that move along a second direction.

[0094] Exemplary, reference Figure 5 Take the screw drive assembly as an example.

[0095] The first sliding assembly 240 is a screw transmission assembly. The first plate body 220 is a rectangular frame structure, and a first screw 241 is disposed within the rectangular frame structure. A first nut (not shown) is disposed on the side of the positioning plate 260 that moves in the first direction toward the first plate body 220. The first nut is inserted into the first screw 241 and can be driven to move along the first screw 241. Specifically, a first drive wheel 242 is engaged at one end of the first screw 241, and the first drive wheel 242 is used to provide power to the screw.

[0096] It is understood that the first sliding assembly 240 enables the positioning plate 260, which moves in the first direction, to move relative to the first plate body 220 in the first direction, thereby adjusting the clamping position of the positioning plate 260 with respect to the workpiece 300 in the first direction. The first driving wheel 242 drives the first nut to move on the first lead screw 241, thereby adjusting the corresponding movement of the positioning plate 260 in the first direction. After the positioning plate 260 moves to the target position in the first direction, the positioning plate 260 is fixed to the positioning hole 270.

[0097] For example Figure 7 As shown, after the second positioning plate 262, the third positioning plate 263, and the fourth positioning plate 264 are moved from position d to position c along the first screw 241 in the first direction, the second positioning plate 262, the third positioning plate 263, and the fourth positioning plate 264 are fixed to the corresponding positioning holes 270 by spring pins, thereby fixing the positioning plate 260 to limit the sheet material 300 to be processed.

[0098] Similarly, the second plate 230 and the positioning plate 260 are connected via a second sliding assembly. Figure 6 The second sliding assembly 250 is a screw transmission assembly. A second screw 251 is provided in the second plate body 230. A second nut (not shown in the figure) is provided on one side of the positioning plate 260 toward the second plate body 230, which is moved in the second direction. The second nut is passed through the second screw 251 and can be driven to move along the second screw 251. Specifically, one end of the second screw 251 is engaged with a second driving wheel 252, and the second driving wheel 252 is used to provide power to the screw. The specific movement process will not be repeated. According to a further embodiment of the present application, the positioning plate 260 includes a first section plate 266 and a second section plate 267, and further reference is made to Figure 4 For better understanding, the first section plate 266 is used to be assembled to the positioning hole 270, and the first end plate is rotatably connected to the second section plate 267. For better understanding, please refer to Figures 2 and Figure 4 As shown, the second section plate 267 switches between a horizontal position e depicted by a dotted line and a vertical position f depicted by a solid line.

[0099] It is understood that after the pallet 200 is transferred to the loading platform 100, the gripping device needs to grasp the sheet material 300 to be processed. During the grasping process, the positioning plate 260, which is perpendicular to the pallet 200, may interfere with the grasping action. In this case, the second plate section 267 can be rotated to a position parallel to the plane of the pallet 200 to avoid interference between the positioning plate 260 and the gripping device.
