Description

Technical Field

[0001] This utility model relates to staple detection equipment, and more specifically, to a staple detection device. Background Technology

[0002] Staples are common consumables in daily office and production processes, and their structural design and manufacturing process directly affect their performance. Individual staples are glued together to form a continuous row that facilitates mechanized operation. The adhesive strength between each staple directly determines the shear strength of the staple body when subjected to shear force during binding. This indicator directly affects the magnitude of the force required for the staple body to break, and directly affects the smoothness of the staple during use.

[0003] Therefore, during the production process of staples, it is necessary to test the bonding strength of the staples. For example, Chinese utility model patent with publication number CN216646218U discloses a staple shear force testing device, which can detect the shear force of the staple pressing down. The pressure during the shear test is obtained through a sensor, which can then reflect the parameters of the staple bonding strength.

[0004] However, in the current solution, the staples need to be manually pressed and restrained on the mold during the staple test to limit and fix the staples, and then the staples are pressed down and sheared. During the test, if the operator's hand is slightly loose, the staples may be lifted up, affecting the stability and accuracy of the shearing test.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a staple detection device that can stably clamp staples and maintain the stability of the testing process.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A staple detection device includes a base with a support mold fixedly mounted on it for mounting staples to be detected. A lifting frame is provided on the upper part of the base, adjustable via a guide rail and driven by a driver. The device also includes a pressure detector and a pressure rod. The pressure detector is fixedly mounted on the lifting frame, has a downward-facing detection end, and is fitted with a detection block. The pressure rod is connected to the lifting frame via an upper and lower sliding rail, and a lower pressure seat is fixedly connected to the upper end of the pressure rod. The lower pressure seat is located above the support mold and is used to press the staples downwards. A receiving groove is formed on the lower side of the lower pressure seat, and a pressure roller is installed in the groove, capable of rolling against the upper side of the staple.

[0009] The present invention is further configured such that the side wall of the receiving groove is provided with an oblong hole running vertically, and the two ends of the pressure roller are fixedly connected to axles, which are rotatably connected to the oblong hole and can be adjusted vertically.

[0010] The present invention is further configured such that a slide rail is provided inside the pressure rod, the lower end of the slide rail is connected to the receiving groove, a movable block is slidably connected inside the slide rail, the lower end of the movable block abuts against the upper side of the pressure roller, and the upper end of the movable block elastically abuts against a spring.

[0011] The present invention is further configured such that the pressure roller has an up-and-down moving stroke within the receiving groove, the pressure roller is located at the lower end of the moving stroke, and the lower side of the pressure roller can protrude out of the receiving groove; the pressure roller is located at the upper end of the moving stroke, and the lower side of the pressure roller is located within the receiving groove.

[0012] The present invention is further configured such that the lifting frame is fixedly connected to an extension frame, the extension frame is fixedly connected to a slider, the pressure rod has a vertically oriented groove, the slider is embedded in the groove, and can slide vertically relative to the lifting frame.

[0013] The present invention is further configured such that a limiting block is fixedly connected to the side of the slider facing away from the extension frame, and the limiting block is in contact with the surface of the pressure rod to achieve horizontal limiting.

[0014] The present invention is further configured such that a connecting block is fixedly connected to the outer side of the pressure rod, an adjusting rod is slidably connected to the connecting block, an upper stop block is fixedly connected to the upper end of the adjusting rod, and a spring is elastically pressed between the upper stop block and the connecting block.

[0015] The present invention is further configured such that a lower stop block is fixedly connected to the lower end of the adjusting rod, and the upper stop block and the lower stop block are respectively located on the upper and lower sides of the connecting block to form a limiting position.

[0016] The present invention is further configured such that a stepped groove is provided on the side of the detection block facing the staple, the stepped groove including a limiting surface facing the staple and a downward stepped surface, the limiting surface being used to block and limit the front end of the staple, and the stepped surface being used to press down the staple.

[0017] The present invention is further configured such that the limiting surface is inclined, and the lower side of the limiting surface is inclined away from the staple direction.

[0018] In summary, this utility model has the following beneficial effects:

[0019] By fixing an extension frame to the outside of the lifting frame, and installing an adjustable pressure bar on the extension frame, the lower pressure seat at the lower end of the pressure bar can apply a pressure force to the staples. The lower pressure seat and the support mold can apply a pressure clamping force to the staples in the vertical direction, thereby stably clamping the staples.

[0020] Through the spring and the movable adjusting rod, an up-and-down buffer adjustment can be formed. During the staple shearing test, it can ensure that the lower end of the pressure rod can always be in contact with the staple, and can also allow the pressure detector and the detection block to continue to press down, thereby enabling the staple to perform a nailing test action.

[0021] In addition, a pressure roller is installed on the lower side of the pressure seat. Under the support of the second spring, the lower side of the pressure roller can be pushed out of the pressure seat when pre-pressed. The rolling action can reduce the friction with the staples, which can both press and restrict the staples and reduce lateral friction, allowing the staples to slide smoothly laterally.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This embodiment discloses a staple detection device, referring to... Figure 1-5 As shown, the device includes a base 1, on which a support mold 2 is fixedly mounted. The support mold 2 has a long strip-shaped structure that is adapted to the shape and size of the staple 100, and can support the staple 100 to be tested. By moving the staple 100, the single nail at the very front of the staple 100 can be extended, thereby realizing the nailing action.

[0030] A lifting frame 3 is installed on the upper part of the base 1. The lifting frame 3 is adjusted by sliding up and down via guide rails 4 and is driven to rise and fall by a driver 5. The lifting frame 3 is a vertically upright sliding rod. A fixing frame 41 is fixedly installed at the upper end of the lifting frame 3 to support and fix it. The driver 5 can be a threaded screw mechanism, which can drive the lifting frame 3 to rise and fall.

[0031] The staple detection device also includes a pressure detector 6 and a pressure rod 7. The pressure detector 6 is a force sensor that can detect the shear force during the staple driving process. The pressure rod 7 serves to press and restrict the staples 100, and can apply downward pressure to the staples, so that the entire row of staples 100 can be pressed and restricted on the support mold 2.

[0032] The pressure detector 6 is fixedly installed on the lifting frame 3. The pressure detector 6 has a downward detection end and is equipped with a detection pressure block 61. The detection pressure block 61 can apply a shearing force to a staple, thereby simulating the state of staple driving, so as to detect the magnitude of the shearing force required for staple driving and determine the quality stability of the staple.

[0033] Reference Figure 5 As shown, the detection block 61 has a stepped groove 611 on the side facing the staple 100. The stepped groove 611 includes a limiting surface 613 facing the staple 100 and a downward stepped surface 612. The limiting surface 613 is used to block and limit the front end of the staple 100, and the stepped surface 612 is used to press down the staple 100. Furthermore, the limiting surface 613 is inclined, and the lower side of the limiting surface 613 is inclined away from the staple 100.

[0034] During the testing process, the limiting surface 613 of the testing block 61 abuts against the front end of the staple 100, limiting the position of the staple 100 so that it is positioned precisely for the staple-driving test. Then, the lifting frame 3 descends, causing the pressure detector 6 and the testing block 61 to descend as well. The stepped surface 612 of the testing block 61 abuts against the frontmost point of the staple 100, thus pressing down the frontmost staple 100 to simulate the staple-driving action. During this simulated staple-driving process, the pressure detector 6 detects the force applied during the downward pressure, thereby obtaining parameters of the staple-driving shear force.

[0035] The upper and lower slide rails of the pressure rod 7 are connected to the lifting frame 3. The pressure rod 7 is located directly above the support mold 2. Under its own weight, it can slide downward. The pressure rod 7 can press down on the staples 100 on the support mold 2 through its own weight to achieve pre-fixation.

[0036] Reference Figure 3 , Figure 4 As shown, a lower pressure seat 72 is fixedly connected to the upper end of the pressure rod 7. The lower pressure seat 72 is located above the support mold 2 and can press the staples downward through the lower pressure seat 72. Furthermore, a receiving groove 722 is formed on the lower side of the lower pressure seat 72, and a pressure roller 73 is installed in the receiving groove 722. The lower side of the pressure roller 73 can press and roll against the upper side of the staple 100.

[0037] Reference Figure 3 As shown, the side wall of the receiving groove 722 has an oblong hole 721 running vertically, and the two ends of the pressure roller 73 are fixedly connected to the axle 731. The size of the axle 731 is adapted to the size of the oblong hole 721, and the axle 731 is rotatably connected in the oblong hole 721 and can be adjusted up and down along the oblong hole 721.

[0038] Reference Figure 4 As shown, a slide 77 is provided inside the pressure rod 7. The lower end of the slide 77 is connected to the receiving groove 722. A movable block 79 is slidably connected inside the slide 77. The upper end of the movable block 79 elastically abuts against a second spring 78. The second spring 78 can apply downward pressure to the movable block 79, while the upper end of the second spring 78 abuts against the upper closed position of the slide 77, which can apply downward pressure to the pressure roller 73 and the movable block 79.

[0039] The lower end of the movable block 79 abuts against the upper side of the pressure roller 73. In order to reduce the friction between the lower end of the movable block 79 and the pressure roller 73, the lower end of the movable block 79 can be set into a ball-head structure, or a ball or roller can be embedded in the lower end of the movable block 79 to reduce frictional resistance.

[0040] Guided by the oblong hole 721, the wheel axle 731 moves up and down within the stroke of the oblong hole 721, thereby allowing the pressure roller 73 to move up and down within the receiving groove 722. Under the elastic action of the second spring 78, the pressure roller 73 is partially pushed downwards, with the pressure roller 73 located at the lower end of its stroke. The lower side of the pressure roller 73 can protrude from the receiving groove 722. (Refer to...) Figure 4 As shown.

[0041] When the pressure rod 7 is subjected to a downward force, it applies pressure to the second spring 78, causing the second spring 78 to contract. The pressure roller 73 then rises relative to the pressure rod 7, reaching the upper end of its travel stroke. At this point, the pressure roller 73 is fully embedded in the receiving groove 722, with its lower side also within the groove. Simultaneously, the lower side of the lower pressure seat 72 abuts against the staple 100, applying a greater frictional force to the staple 100.

[0042] Reference Figure 3 , Figure 4 As shown, the lifting frame 3 is fixedly connected to an extension frame 31, and the extension frame 31 is fixedly connected to a slider 32. The pressure rod 7 has a vertically oriented groove 71, and the slider 32 is embedded in the groove 71 and can slide vertically relative to it. Furthermore, a limiting block 33 is fixedly connected to the side of the slider 32 facing away from the extension frame 31. The limiting block 33 is in contact with the surface of the pressure rod 7 to achieve horizontal limiting. The limiting block 33, the extension frame 31, and the slider 32 are fixedly connected to each other. Limiting is achieved on both sides of the slider 32 through the limiting block 33 and the extension frame 31, thereby forming a blocking limit on both the front and rear sides of the pressure rod 7, which can serve as a guide for the slide.

[0043] Reference Figure 3 As shown,

[0044] A connecting block 74 is fixedly connected to the outer side of the pressure rod 7, and an adjusting rod 75 is slidably connected to the connecting block 74. A vertically extending slide is opened in the middle of the connecting block 74, and the adjusting rod 75 passes through the slide of the connecting block 74, allowing the adjusting rod 75 to slide up and down for adjustment. Furthermore, an upper stop block 751 is fixedly connected to the upper end of the adjusting rod 75, and a spring 76 elastically presses against the upper stop block 751 and the connecting block 74. The spring 76 provides vertical sliding guidance and elastic support between the connecting block 74 and the upper stop block 751, transmitting the vertical pressing force between the limiting block 33 and the connecting block 74.

[0045] Furthermore, a lower stop 752 is fixedly connected to the lower end of the adjusting rod 75. The upper stop 751 and the lower stop 752 are located on the upper and lower sides of the connecting block 74 respectively to form a limit. The lower stop 752 can prevent the adjusting rod 75 from displacing upward.

[0046] During the shear force test of the staple 100, a support mold 2 of appropriate size is installed on the base 1, and the staple 100 to be tested is installed on the support mold 2; the driver 5 is pushed to work, causing the fixing frame 41 to descend, pressing down the pressure detector 6, and the detection block 61 at the lower end of the pressure detector 6 presses against the front end of the staple 100; at the same time, the lower pressure seat 72 at the lower end of the pressure rod 7 abuts against the upper side of the staple 100, and under the action of the spring 78, the pressure roller 73 can protrude slightly and abut against the upper side of the staple 100. By rolling, the friction with the staple 100 can be reduced, which can achieve pressure restriction on the staple 100 while reducing lateral friction, allowing the staple 100 to slide smoothly laterally for adjustment.

[0047] Then, the lifting frame 3 and the extension frame 31 descend further, the limiting block 33 presses against the upper stop block 751, and the spring 1 76 and the pressure rod 7 apply a downward force to the pressure rod 7; as the downward pressing force of the limiting block 33 increases, the spring 2 78 can be compressed, the pressure roller 73 will be completely embedded in the receiving groove 722, and the plane on the lower side of the lower pressure seat 72 can be opposite to the staple 100, thereby pressing and fixing the staple 100.

[0048] The limiting surface 613 abuts against the front end of the staple 100, and the stepped surface 612 abuts against the first staple at the front end of the staple 100, which can apply downward pressure to a staple 100, thereby applying a shearing action to the staple, and detecting the shearing force during the shearing process.

[0049] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
