DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0029] Example 1: See Figure 1-4 As shown, a stainless steel stamping feeding device includes a supporting component and a feeding component, the supporting component includes a bottom plate 1, a slide plate 2 arranged on the bottom plate 1, three groups of storage racks 3 installed on the slide plate 2 and arranged at intervals in the horizontal direction, and a first driving part driving the slide plate 2 to move in the horizontal direction along the bottom plate 1, a storage cavity 4 is arranged in the storage rack 3, and the two ends of the storage cavity 4 are respectively connected with the top surface and the bottom surface of the storage rack 3, and the bottom of the slide plate 2 is provided with a first through groove 5 corresponding to the storage cavity 4, and the rear side of the first through groove 5 is connected with the rear side surface of the slide plate 2 (only one group of storage racks is shown in the figure, and the two groups of storage racks are not shown, and the two groups of storage racks at the two first through grooves are not shown);

[0030] The feeding component includes a stand 6, a feeding plate 7 vertically slidably arranged on the stand 6, and a second driving part driving the feeding plate 7 to move vertically. The bottom plate 1 is provided with a second through slot 8 penetrating the top and bottom surfaces of the bottom plate 1. The rear side of the second through slot 8 is connected to the rear side surface of the bottom plate 1. The middle part of the stand 6 is connected to the rear inner wall of the second through slot 8. The feeding plate 7 is arranged opposite to the second through slot 8.

[0031] The first driving part drives the slide plate to move horizontally, and any of the first through slots is arranged opposite to the second through slot, and the feeding plate moves along the stand and passes through the second through slot and the corresponding first through slot.

[0032] In this embodiment, the feeding device is arranged beside the stamping equipment, and a material grabbing manipulator is arranged above the feeding plate, which is used to lift the material in the storage cavity by the feeding plate and grab it and put it into the stamping equipment to realize automatic feeding. In this embodiment, when in use, the sheet stainless steel material (product) to be stamped is placed in the two groups of storage cavities in advance, and the products are stacked from bottom to top. In the initial state, the feeding plate will be inside the second through groove, or below the second through groove. When feeding is required, the second driving unit drives the feeding plate to move upward, and the feeding plate passes through the second through groove and the first through groove and is inserted into the storage cavity (first grab the product in the left storage rack as an example), and the top surface of the feeding plate is against the bottom surface of the bottom product. After the manipulator grabs a product, the second driving unit drives the product to move upward by a distance of the thickness of the product, so that the height of the top product in the storage cavity is maintained at a preset position, and when the subsequent manipulator grabs the product again, it can be grabbed smoothly and stably. After the products in the left storage chamber are caught, the second driving unit drives the grabbing plate to move down quickly to leave the left storage chamber and move into the second through slot or move to the bottom of the second through slot, and then the first driving unit drives the slide plate to move to the left, so that the first through slot of the right storage chamber is opposite to the second through slot, and then the second driving unit drives the feeding plate to move upward and against the bottom surface of the product at the bottom of the right storage chamber, and repeats the above actions to push the products in the storage chamber upward. In this configuration, the operator can stack the products again and put them into the storage chamber of the empty storage rack on the left. In this way, the stamping equipment does not need to be stopped, and there is no need to manually put the products into the stamping equipment. The feeding device and the stamping equipment can operate uninterruptedly, which improves the stamping efficiency and reduces the labor intensity of the operator. In addition, only one set of feeding plates and one set of second driving units are needed to realize the lifting of products in two sets of storage racks, which can reduce costs.

[0033] See also Figure 1 , 2 As shown, a transverse slide rail 9 is disposed on the bottom plate 1 , the slide plate 2 is slidably disposed on the transverse slide rail 9 , and the transverse slide rail 9 is disposed at the front side of the first through slot 5 .

[0034] The first driving part is arranged on the bottom plate 1 at the front side of the slide plate 2, and the first driving part includes a first transverse slide rail 10, a first slider 11, a first motor 12, a first gear and a first rack (the first gear and the first rack are not shown in the figure), the first transverse slide rail 10 is arranged on the bottom plate 1 at the front side of the slide plate 2, the first rack is installed on the first transverse slide rail 10, the first slider 11 is slidably arranged on the first transverse slide rail 10, and the first slider 11 is detachably connected to the slide plate 2 via a connecting plate 13;

[0035] The first motor 12 is mounted on the first slider 11 , the first gear is connected to the output shaft of the first motor, and the first gear is meshed with the first rack.

[0036] In this embodiment, the first transverse slide rail is arranged at the front side of the transverse slide rail, and the first driving part adopts the arrangement of the first motor, the first gear and the first rack. When the first motor drives the first rotation, the first gear and the first rack can be meshed to quickly drive the slide plate to move, thereby realizing the rapid and accurate displacement of the product. More preferably, the first motor can also be connected to the first gear through a reducer to realize the stable movement of the first gear, and the first motor can use a smaller power to reduce the cost.

[0037] See also Figure 1 , 2 As shown, the second driving part includes a vertical slide rail 14, a vertical lead screw and a second motor 15 (the vertical lead screw is not shown in the figure), the vertical slide rail 14 is vertically installed on the front side of the stand 6, the vertical lead screw is parallelly arranged on the side of the vertical slide rail 14, both ends of the vertical lead screw are rotatably connected to the stand 6, and the second motor 15 is configured to drive the vertical lead screw to rotate;

[0038] A vertical slider 16 is slidably provided on the vertical slide rail 14, the rear end of the feed plate 7 is connected to the vertical slider 16, the lead screw is screwed to the vertical slider 16, and when the vertical slider 16 moves along the vertical slide rail 14, the feed plate 7 moves up and down and passes through the second through groove 8.

[0039] In this embodiment, a combination of a vertical screw and a second motor is used to achieve vertical movement of the feed plate, and the combination of the screw and the motor has high driving accuracy, ensuring that the distance the feed plate moves up each time is accurate, thereby ensuring the accuracy and stability of subsequent material grabbing by the robot.

[0040] See also Figure 2 , 3 As shown, the material storage rack 3 includes a mounting plate 17, a top frame 18 and four vertical poles 19. The bottom surface of the mounting plate 17 is fixedly mounted on the top surface of the slide plate 2. The mounting plate 17 is provided with a make way groove 20 facing the first through groove 5. The top frame 18 is a hollow structure. The top frame 18 is arranged directly above the mounting plate 17. The tops of the four vertical poles 19 are respectively connected to the four corners of the bottom surface of the top frame 18, and the bottoms of the four vertical poles 19 are respectively connected to the four corners of the top surface of the mounting plate 17. The four vertical poles surround and form the material storage cavity.

[0041] In this embodiment, the first through slot is arranged between the two rear vertical rods, so that the feeding plate is not affected to move up and down and enter the material storage cavity to carry out the product support. The four vertical rods are surrounded to form a square structure.

[0042] More preferably, a support plate 21 is placed on the mounting plate 17, and the support plate 21 is arranged just above the clearance groove 20. The setting of the support plate can support products of different sizes. For example, if the size of the product is smaller than the size of the first through groove, the setting of the support plate can prevent the product from falling from the first through groove. Of course, if the size of the product is larger than the width of the first through groove, the support plate may not be provided. However, in order to prevent the side of the product from being stuck in the first through groove, it is preferred to put a support plate in to support the product at the bottom.

[0043] See also Figure 3 , 4 As shown, at least one limiting member is provided between adjacent vertical poles 19, and the limiting member includes a limiting rod 22, and the two ends of the limiting rod 22 are rotatably connected to the top frame 18 and the mounting plate 17 via a connecting rod 23; the connecting rod 23 is L-shaped, V-shaped or straight-shaped, and one end of the connecting rod 23 is rotatably connected to the top frame 18 or the mounting plate 17, and the end of the vertical pole 19 is connected to the other end of the connecting rod 23.

[0044] In this embodiment, in order to prevent the products from falling out from between adjacent vertical poles and to prevent the stacked products from tipping over, a limiting rod is further provided to limit the side of the product.

[0045] See also Figure 3 , 4 As shown, the end of the upper connecting rod 23 is rotatably connected to the bottom of the top frame 18 via a rotating shaft 24, and the connecting rod 23 can move axially relative to the rotating shaft 24, and the end of the lower connecting rod 23 is rotatably connected to the mounting plate 17 via a bolt 25; a spring 26 is sleeved on the bolt 25, the top of the spring 26 abuts on the bottom surface of the screw head of the bolt 25, and the bottom of the spring 26 abuts on the bottom surface of the lower connecting rod 23, the spring pushes the lower connecting rod to move downward, and makes the bottom surface of the lower connecting rod abut against the top surface of the mounting plate.

[0046] More preferably, in order to limit the position of products of different sizes and shapes, so that when the feeding plate moves up, the product can only move vertically stably and will not fall over. Therefore, the two ends of the limit rod are respectively connected to the top frame and the mounting plate through L-shaped, V-shaped or straight-shaped limit rods, and a rotating connection method is adopted, so that when the limit rod rotates around the top frame and the mounting plate through the connecting rod, the limit rod can be transferred to different positions in the limit cavity, and the limit rod is close to or against the outer wall of the product to limit the product and prevent the product from falling over. Furthermore, in order to ensure that after the limit rod limits the position of the product, it will not rotate around the top frame and the mounting plate through the connecting rod, a spring is also provided. The spring uses the screw head of the bolt to give downward pressure to the lower connecting rod, so that the lower connecting rod will not rotate when subjected to a certain external force, that is, the limit rod will not deviate. If the size and shape of the product are changed, the operator grabs the limit rod and drives it to rotate around the top frame and the mounting plate through the connecting rod, so that the limit rod is set close to or away from the center of the storage chamber, until the limit rod is against the side of the product or close to the side of the product, and the product is limited. In this way, it can be applied to products of different sizes and shapes, improving the scope of application, and there is no need to replace storage racks of different sizes and shapes (the width of the product will be smaller than the internal width of the top frame, so that the product can be smoothly sent out of the storage chamber from the middle of the top frame), thereby reducing costs. In this embodiment, some connecting rods are L-shaped, some connecting rods are V-shaped, and some connecting rods are I-shaped structures, which can be selected or adjusted according to actual conditions.

[0047] Wherein, the support plate is arranged between the plurality of limit rods; the outer side surface of the support plate is arranged close to the plurality of limit rods, or the outer side surface of the support plate is in contact with the plurality of limit rods. In this embodiment, if the size and shape of the support plate are adapted to the product, the limit rods are in contact with or close to the side wall of the support plate, and the product can be restricted while limiting the position of the support plate.

[0048] The width of the feeding plate is smaller than the width of the first through slot and the second through slot. In this way, the feeding plate can enter the material storage cavity and can also escape from the material storage cavity when it moves up and down.

[0049] The end of the vertical rod is rotatably connected to the connecting rod, and the other end of the connecting rod is provided with a strip groove 27 (of course, according to actual conditions, there are also connecting rods that do not have a strip groove at the end, but only a hole that matches the corresponding bolt or shaft). The shaft is inserted into the strip groove of the upper connecting rod, and the width of the strip groove is adapted to the shaft, and the length of the strip groove is greater than the diameter of the shaft. The bolt is inserted into the strip groove of the lower connecting rod, and the diameter of the bolt is adapted to the width of the strip groove, and the diameter of the bolt is smaller than the width of the strip groove. The provision of the strip groove enables the limit rod to adjust the distance between the vertical rod and the edge of the top frame through the strip groove of the connecting rod, so that the position of the limit rod has a larger bar range and is easier to adjust.
