Description

Technical Field

[0001] This utility model relates to the field of automation equipment, and in particular to an automatic material peeling machine. Background Technology

[0002] In the production of gaskets for electronic products, the material is formed by stamping with a mold. The material strip enters the mold position at a certain frequency, and then, under the action of the mold, gasket products and waste strips are formed. At this point, high-pressure gas can be used to blow the gasket products out of the mold position, and the waste strip is then wound up and collected separately. However, after the gasket products are blown out by high-pressure gas, all the gasket products are collected in a collection box. The gasket products in the collection box are messy and disordered. In order to facilitate subsequent production and transportation, all the gaskets need to be neatly arranged. This can only be done manually, which greatly increases the workload and the sorting efficiency is extremely low, resulting in an increase in production costs. Utility Model Content

[0006] In one embodiment, a limiting plate is provided on the upper side of the conveyor belt, and a groove is provided on the lower side of the limiting plate. The groove is located between the conveyor belt and the limiting plate to form a channel through which the conveyor belt passes. A vertical groove adapted to the first vertical bar and the second vertical bar is provided on the upper side of the limiting plate. When the pressing block is pressed against the upper side of the limiting plate, the bottom of the first vertical bar and the second vertical bar contact the product at the position of the conveyor belt, pressing the product out from the peeling groove position.

[0007] In one embodiment, the conveyor belt is provided with a slot, and a driving structure is provided at the slot position for driving the conveyor belt to move on the conveyor belt.

[0008] In one embodiment, the drive structure includes a drive roller disposed on the lower side of the conveyor belt, with a portion of the drive roller protruding above the conveyor belt at a slotted position. A drive motor for controlling the rotation of the drive roller is provided on the side of the drive roller. The drive structure also includes a pressure roller cylinder fixed to the side of the fixed vertical plate. The piston rod of the pressure roller cylinder is connected to a U-shaped connecting plate, and a pressure shaft is connected to the middle of the U-shaped connecting plate via a bearing. The pressure shaft moves up and down under the action of the pressure roller cylinder, and the conveyor belt passes between the pressure shaft and the drive roller.

[0009] In one embodiment, the receiving structure includes a rotating disk, which is rotatably mounted on the upper side of the worktable via a rotary table. A plurality of receiving rods are provided on the upper side of the rotating disk, and the receiving rods are detachably connected to the rotating disk. Under the action of the rotary table, the receiving rods rotate to the position below the peeling groove for collecting the peeled products.

[0010] In one embodiment, the upper side of the rotating disk is provided with a fixed base plate, and the upper side of the fixed base plate is provided with two fixed blocks. The two fixed blocks are spaced apart, and the ends of the fixed blocks are provided with end plates. The two fixed blocks are provided with stepped portions on opposite sides. The fixed blocks and the fixed base plate form a T-shaped groove. The bottom of the receiving rod is provided with a matching T-shaped block, and the receiving rod is engaged in the T-shaped groove by the bottom T-shaped block.

[0011] In one embodiment, the T-shaped block is provided with a magnet on its side, and the end plate is provided with a corresponding adsorption part on its side. When the T-shaped block of the receiving rod is engaged in the T-shaped groove, the T-shaped block is fixed in the T-shaped groove by the magnet.

[0012] In one embodiment, the waste roll includes a take-up roll fixed to the upper side of the workbench by a bracket, and a take-up motor is provided on the side of the take-up roll for controlling the rotation of the take-up roll.

[0013] In one embodiment, a tension adjustment structure is further provided between the waste roll and the conveyor belt.

[0023] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figures 1 to 2 As shown, an automatic stripping machine is characterized by comprising a workbench 1, a material conveyor plate 2 fixed on the upper side of the workbench 1 via a fixed vertical plate, the material conveyor plate 2 being horizontally arranged, the material conveyor plate 2 being provided with a stripping groove 21, a stripping structure 3 being provided on the upper side of the stripping groove 21, a material collection structure 4 being provided on the lower side of the stripping groove 21, and a waste roll 5 for collecting waste material strips being provided on the upper side of the workbench 1. After the material strip is punched, the product falls from the stripping groove 21 to the material collection structure 4 under the action of the stripping structure 3, and the remaining waste material strips are collected by the waste roll 5.

[0027] After the product stamping is completed, the product and the material strip continue to move. When it moves to the peeling groove 21, the peeling structure 3 will separate the product from the material strip (waste strip). The product is collected by the collecting structure 4, and the waste strip is collected by the waste roll 5, thereby realizing the separation and collection of the product and the waste strip, and improving the production efficiency of the product.

[0028] In the front-end stamping process, only a small portion of the product and the waste strip are connected, thus requiring better separation. The peeling structure 3 peels the product from the strip, forming separate products and waste strips. Specifically, in this embodiment, the peeling structure 3 includes a peeling cylinder 31, which is fixed to the side of a fixed vertical plate by a fixing plate. The piston rod of the peeling cylinder 31 is connected to a pressure block 32, which has a first vertical bar 321 and a second vertical bar 322. The first vertical bar 321 and the second vertical bar 322 act on the side of the product on the strip. Under the action of the peeling cylinder 31, the pressure block 32 moves downwards, causing the first vertical bar 321 and the second vertical bar 322 to move downwards as well. The product, having moved to this position, separates from the strip under the action of the first vertical bar 321 and the second vertical bar 322, and falls into the collection structure 4 at the peeling groove 21 for collection.

[0029] At this time, the first vertical bar 321 and the second vertical bar 322 are adapted to the width of the product. That is, when the first vertical bar 321 and the second vertical bar 322 move downward, they are aligned with the product. This allows the product to be pressed out from the material belt position. At this time, it is necessary to ensure that the product on the material belt moves to the peeling groove 21 position. That is, the material belt needs to be positioned. Specifically, at this time, positioning holes are provided on both sides of the material belt (located at the waste material belt position). The alignment holes are set to correspond to the product. A sensor is set on the upper side of the material belt transmission plate 2 to detect the positioning position of the material belt, thereby detecting the position of the product. This ensures that the product can be pressed out normally and fall into the collection structure 4 for collection after being pressed out.

[0030] In order to ensure the smooth extrusion of the product during the extrusion process, in this embodiment, a limiting plate 6 is provided on the upper side of the conveyor belt 2, and a groove is provided on the lower side of the limiting plate 6. The groove is located between the conveyor belt and the limiting plate 6 to form a channel for the conveyor belt to pass through. The upper side of the limiting plate 6 is provided with a vertical groove that is adapted to the first vertical bar 321 and the second vertical bar 322. When the pressing block 32 presses against the upper side of the limiting plate 6, the bottom of the first vertical bar 321 and the second vertical bar 322 contacts the product at the position of the conveyor belt, and the product is pressed out from the peeling groove 21. Under the action of the limiting plate 6, the flatness of the entire strip at the peeling groove 21 can be ensured, thus ensuring normal product extrusion. At the same time, the limiting plate 6 has a certain thickness. When the first vertical bar 321 and the second vertical bar 322 move up and down in the vertical groove, the distance of their up and down movement can be controlled by the limiting plate 6. At this time, when the first vertical bar 321 and the second vertical bar 322 move to the lowest point, the bottom of the first vertical bar 321 and the second vertical bar 322 slightly extends to the lower side of the strip. This can both extrude the product from the strip and quickly separate it from the strip when the first vertical bar 321 and the second vertical bar 322 move upward, thereby ensuring a faster production rhythm and improving production efficiency.

[0031] When the product separates from the conveyor belt, the conveyor belt needs to remain in motion. Therefore, in this embodiment, the conveyor belt 2 has a slot, and a driving structure 7 is provided at the slot to drive the conveyor belt to move on the conveyor belt 2. Under the action of the driving structure 7, the conveyor belt moves on the upper side of the conveyor belt 2 at a certain frequency, so that the peeling structure 3 presses the product out of the conveyor belt position at a certain frequency. At this time, in order to reduce the impact on the product, the driving structure 7 is set at the position below the peeling structure 3, that is, at the side of the peeling structure 3.

[0032] Specifically, the drive structure 7 includes an active roller 71, which is disposed on the lower side of the material conveyor plate 2. A portion of the active roller 71 protrudes to the upper side of the material conveyor plate 2 at the slotted position. A drive motor for controlling the rotation of the active roller 71 is provided on the side of the active roller 71. The drive structure 7 also includes a pressure roller cylinder 72 fixed to the side of the fixed vertical plate. The piston rod of the pressure roller cylinder 72 is connected to a U-shaped connecting plate 73. The middle part of the U-shaped connecting plate 73 is connected to a pressure shaft 74 through a bearing. The pressure shaft 74 moves up and down under the action of the pressure roller cylinder 72, and the material belt passes between the pressure shaft 74 and the active roller 71. At this point, after the product is separated from the conveyor belt, there is still waste material remaining. The waste material passes between the pressure shaft 74 and the drive roller 71. Part of the drive roller 71 extends to the upper side of the conveyor belt 2, while the pressure roller is located directly above the drive roller 71. Under the action of the pressure roller cylinder 72, the pressure roller moves downward, thereby clamping the waste material between the pressure shaft 74 and the drive roller 71. Then, the drive roller 71 rotates under the action of the drive motor, and the waste material moves between the pressure shaft 74 and the drive roller 71, thereby realizing the forward movement of the conveyor belt.

[0033] After the product is pressed out from the conveyor belt, it needs to be collected. At this time, the product is thin. In this embodiment, in order to improve the collection efficiency, the collection structure 4 includes a rotating disk 41. The rotating disk 41 is rotatably set on the upper side of the worktable 1 via a rotating table. Several collection rods 42 are provided on the upper side of the rotating disk 41. The collection rods 42 are detachably connected to the rotating disk 41. The collection rods 42 rotate to the lower side of the peeling groove 21 under the action of the rotating table to collect the peeled product. Under the action of the rotary table, the rotating disk 41 rotates on the upper side of the worktable 1, while multiple receiving rods 42 can rotate sequentially to the lower position of the peeling groove 21 according to the settings. At this time, in order to collect the pressed products neatly, the receiving rods 42 are used to collect the products. The receiving rods 42 are set vertically, with two receiving rods 42 in a group, and the two receiving rods 42 are set at intervals, corresponding to the two holes of the product. In this way, when the product falls to the receiving rod 42 for collection, the two holes of the product are exactly through the receiving rod 42. When the product is through the receiving rod 42, it is basically in a horizontal state. This can ensure that the product can fall to the receiving rod 42 when it is pressed out, and can also arrange all the collected products in order, thereby improving the product collection efficiency.

[0034] After a certain quantity of products are collected on the receiving rod 42, the rotating disk 41 needs to be rotated. The empty receiving rod 42 moves to the lower side of the stripping groove 21. The full receiving rod 42 needs to be removed to replace the empty receiving rod 42. Therefore, in this embodiment, the receiving rod 42 and the rotating disk 41 need to be set as a detachable structure. Specifically, the rotating disk 41 is provided with a fixed base plate 43 on the upper side. The fixed base plate 43 is provided with two fixed blocks on the upper side. The two fixed blocks are spaced apart. The ends of the fixed blocks are provided with end plates. The two fixed blocks are provided with stepped portions on opposite sides. The fixed blocks and the fixed base plate 43 form a T-shaped groove 44. The bottom of the receiving rod 42 is provided with a matching T-shaped block 421. The receiving rod 42 is engaged in the T-shaped groove 44 by the bottom T-shaped block 421. The receiving rod 42 is engaged with the T-shaped groove 44 on the upper side of the rotating disk 41 via the T-shaped block 421 at the bottom, thereby detachably connecting the receiving rod 42 to the rotating disk 41 for easy removal and installation of the receiving rod 42. At this time, the T-shaped block 421 and the T-shaped groove 44 can better position the receiving rod 42 as a whole. This ensures the accuracy of the position of the receiving rod 42 when it is engaged (via the T-shaped block 421 at the bottom) in the T-shaped groove 44, and can catch the falling products when it moves to the lower side of the peeling groove 21.

[0035] In order to ensure that the T-shaped block 421 is fully engaged in the T-shaped groove 44 when it is engaged in the T-shaped groove 44, in this embodiment, the side of the T-shaped block 421 is provided with a magnet, and the side of the end plate is provided with a corresponding adsorption part. When the T-shaped block 421 of the receiving rod 42 is engaged in the T-shaped groove 44, the T-shaped block 421 is fixed in the T-shaped groove 44 by magnetic adsorption. By providing a magnet on the side of the T-shaped block 421 and providing an adsorption part (magnet or iron material) on the end plate of the T-shaped groove 44, the T-shaped block 421 of the receiving rod 42 can be fully engaged in the T-shaped groove 44, thereby ensuring the accuracy of the position of the receiving rod 42. When it moves to the lower side of the peeling groove 21, it can catch the falling product. During the rotation of the turntable, the T-shaped block 421 (receiving rod 42) will not fall out.

[0036] Waste roll 5 is located at the last workstation and is used to collect waste strips. In this embodiment, the waste roll 5 includes a take-up roll 51 fixed to the upper side of the workbench 1 by a bracket. A take-up motor is provided on the side of the take-up roll 51 to control its rotation. Under the action of the take-up motor, the take-up roll 51 rotates, thereby completing the collection of waste strips.

[0037] During the waste strip collection process, it is necessary to ensure that the waste strip wrapped around the outside of the take-up roll 51 is as compact as possible. However, the moving speed of the strip is affected by the peeling process. Therefore, a tension adjustment structure 8 is provided between the drive structure 7 and the take-up roll 51 to adjust the tension of the waste strip. Specifically, the tension adjustment structure 8 includes a connecting block fixed to the upper side of the workbench 1 by a bracket. The side of the connecting block is provided with a first rotating shaft 81 and a second rotating shaft 82 via bearings. The lower side of the connecting block is provided with a vertical guide rod 83. The vertical guide rod 83 is provided with a sliding rod that slides up and down. The side of the sliding rod is provided with a third rotating shaft 84 via bearings. The strip passes from the upper side of the first rotating shaft 81, through the lower side of the third rotating shaft 84, and then through the second rotating bearing to the position of the waste roll 5. Under the influence of gravity, the sliding rod and the third rotating shaft 84 move downward along the vertical guide rod 83. At this time, the waste strip is located below the third rotating shaft 84, meaning the waste strip can support the third rotating shaft 84. During the collection process, the take-up motor does not need to constantly control the take-up roll 51 to rotate. Under the action of the drive motor, the waste strip of the peeled product increases. Thus, the waste strip located between the take-up roll 51 and the drive motor becomes longer, while the third rotating shaft 84 presses on the upper side of the waste strip. After the waste strip becomes longer, the third rotating shaft 84 moves downward. At this time, the waste strip always remains taut, which can prevent the waste strip from getting tangled. When the third rotating shaft 84 moves down to a certain position, the take-up motor rotates, winding the waste strip to the outside of the take-up roll 51, thereby achieving orderly collection of the waste strip.

[0038] At this time, a limiting rod is also provided on the side of the vertical guide rod 83. The limiting rod is equipped with an upper limit block and a lower limit block. The sliding rod slides up and down along the vertical guide rod 83. When the sliding rod moves to the uppermost and lowermost positions, it abuts against the upper limit block and the lower limit block respectively, so that the sliding rod continues to slide up and down, thereby limiting the highest and lowest positions of the third rotating shaft 84. In this way, the collection of waste strip can be completed by controlling the collecting motor to drive and run at a certain frequency.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
