The setting of the control slide groove 27 can limit the sliding range of the control block 28, and can prevent the control block 28 from deviating during the sliding process, so that the control block 28 can always slide within the limited range, a glue-spreading rod 5 is arranged on one side of the control block 28, and a plurality of glue-spreading nozzles 51 for applying glue to the composite board 16 are arranged on the glue-spreading rod 5. Through the setting of the plurality of glue-spreading nozzles 51, the glue can be evenly applied to the composite board 16, and a placement block is arranged on the same side of the fixed shell on the fixed frame, and the placement block is located below the fixed shell, and a placement groove 18 is provided on the placement block 17; The lower end of the rotating tube 22 is fixedly connected with a scraper 52, which is used to scrape the glue flat on the composite board 16. The design of the scraper 52 allows the glue applied on the composite board 16 to be flattened and evenly scraped, thereby preventing the glue from being unevenly applied. The composite board 16 after the glue is applied is adhered with a limiting block 15; An annular groove 3 is provided on the lower side of the fixed plate 21, and a sliding ball 4 is slidably connected in the annular groove 3. The design of the annular groove 3 can guide the sliding trajectory of the sliding ball 4. At the same time, the sliding ball 4 is embedded in the annular groove 3, which can prevent the sliding ball 4 from escaping from the restriction of the annular groove 3. A control rod 41 is fixedly connected to one side of the sliding ball 4.

[0028] See Figure 1 First, place the composite board 16 to be tested on the placement groove 18 of the placement block 17, then start the equipment to apply glue to the composite board 16, place the glue spray nozzle 51 on one side of the composite board 16, and then start the equipment. Figure 5 , the first gear 25 is driven to rotate by the power motor 24, and the first gear 25 rotates while driving the second gear 23 to rotate together, and the rotation of the second gear 23 drives the rotating tube 22 to rotate together, and the rotating tube 22 rotates while driving the control block 28 to rotate together, thereby driving the glue-spreading rod 5 and the glue-spreading nozzle 51 to rotate on one side of the composite board 16, so that the glue can be applied on one side of the composite board 16; after the glue is applied on the composite board 16, the rotation of the rotating tube 22 can drive the scraper 52 to rotate together, so that the scraper 52 can scrape the glue applied on the composite board 16 evenly, and at the same time, the length of the scraper 52 is much greater than the length of the glue-spreading rod 5. Through such a design, the scraper 52 can scrape the glue sprayed by the glue-spreading nozzle 51 flat, so as to prevent the situation where the glue on the composite board 16 cannot be scraped; Then, the side of the composite plate 16 coated with glue is attached to the limiting block 15 , and the limiting block 15 and the composite plate 16 are bonded together under the action of the glue, and then the other side of the composite plate 16 is coated with glue.

[0029] In this embodiment: the rotation of the rotating tube 22 causes the glue coating rod 5 and the glue coating nozzle 51 to rotate together, so that the glue can be applied to one side of the composite plate 16. At the same time, the rotation of the scraper 52 evenly spreads the glue applied on the composite plate 16 on one side of the composite plate 16, so that there is sufficient adhesion between the composite plate 16 and the limiting block 15, preventing the occurrence of insufficient adhesion, so that subsequent detection results can be more accurate.

[0030] Embodiment 2: This embodiment is intended to promote the solution of the problem that the glue spraying nozzle 51 does not have a sufficient application range when applying glue to the composite board 16. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 8 A through slot 211 is provided in the middle of the control block 28, and an inclined slot 29 is provided on the side wall of the through slot 211. The inclined slot 29 is connected to the vertical slide slot 210, and the inclined slot 29 and the vertical slide slot 210 are connected to each other. The design of providing the through slot 211 on the control block 28 can provide sufficient activity space for the control rod 41 to prevent the control rod 41 from being stuck in the control block 28.

[0031] A sliding column 44 is disposed on the control rod 41 . The control rod 41 passes through the control block 28 via the through slot 211 , and the control rod 41 is slidably connected to the control block 28 .

[0032] The annular chute 3 includes a smooth groove 31, a first inclined chute 32, a straight chute 33, a first wave chute 34, a second wave chute 35 and a second inclined chute 36. The smooth groove 31, the first inclined chute 32, the straight chute 33, the first wave chute 34, the second wave chute 35 and the second inclined chute 36 are connected to each other. The sliding ball 4 is guided by the annular chute 3 so that the sliding ball 4 can drive the control rod 41 to slide up and down; at the same time, the smooth groove 31, the first inclined chute 32, the straight chute 33, the first wave chute 34, the second wave chute 35 and the second inclined chute 36 are all provided with multiple sections, and each section is connected end to end and has a certain arc shape to form a circular chute; When the sliding ball 4 is located in the straight sliding groove 33, the control rod 41 slides downward to the lowest position.

[0033] The sliding column 44 is slidably connected with the inclined groove 29 and the vertical sliding groove 210; When the sliding column 44 is slidably connected to the inclined groove 29, the glue coating rod 5 and the glue coating nozzle 51 slide to the right. Through the guidance of the sliding column 44 by the inclined groove 29, the control rod 41 can drive the glue coating nozzle 51 to slide horizontally while driving the sliding column 44 to slide downward.

[0034] See Figure 7 When the rotating tube 22 rotates, the control rod 41 is driven to rotate together through the control block 28. When the control rod 41 rotates, the sliding ball 4 is driven to slide in the annular groove 3. Figure 6 When the sliding ball 4 slides from the smooth groove 31 into the first inclined groove 32, the sliding ball 4 is guided by the first inclined groove 32, so that the sliding ball 4 gradually slides downward, and at the same time drives the control rod 41 to slide downward. When the control rod 41 slides downward, it drives the sliding column 44 to slide in the inclined groove 29, so that the control block 28 moves horizontally to the right under the guidance of the inclined groove 29. While the control block 28 slides to the right through the control groove 27, it drives the glue rod 5 and the glue nozzle 51 to slide together, thereby increasing the coating area of ​​the glue nozzle 51; when the sliding ball 4 slides from the first inclined groove 32 into the straight groove 33, the sliding ball 4 is at the lowest point at this time, and the sliding column 44 is at this time located in the vertical groove 210, and the control block 28 has also slid to the far right.

[0035] It should be noted that even if the control block 28 drives the glue coating rod 5 and the glue coating nozzle 51 to slide horizontally, the length of the scraper 52 is sufficient to smear the glue sprayed by the glue coating nozzle 51, and the scraper 52 will not fail to scrape the glue sprayed by the glue coating nozzle 51.

[0036] In this embodiment: by controlling the lateral sliding of the block 28, the glue coating rod 5 and the glue coating nozzle 51 can be driven to slide laterally together, thereby increasing the coating area of ​​the glue coating nozzle 51 on the composite plate 16 to a certain extent, so that every corner of the composite plate 16 can be coated with glue, and then the scraper 52 is used to scrape the glue so that the glue can be more evenly coated on the composite plate 16, and the glue can be further evenly coated on the composite plate 16, thereby increasing the adhesion between the limiting block 15 and the composite plate 16, and preventing the composite plate 16 from generating stress concentration during the stretching process due to uneven glue coating. In areas with less glue, the composite plate 16 may break or be damaged prematurely due to excessive stress, thereby affecting the accurate evaluation of the overall strength test of the composite plate 16.

[0037] Embodiment 3: This embodiment is intended to promote the solution of the problem that a lot of glue will adhere to the scraper 52 during the process of scraping glue. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 8 The middle end of the control rod 41 is fixedly connected with a resisting round block 42, and the lower side of the resisting round block 42 is in contact with a first spring 43, and the other end of the first spring 43 is in contact with the upper side of the mounting block 26. Through the design of the resisting round block 42, the upper end of the first spring 43 can be restricted, and through the cooperation of the upper side of the mounting block 26, a certain support can be provided for the subsequent resetting of the first spring 43.

[0038] The push plate 54 is provided with a second spring 55 at one end of the control rod 41, and one end of the second spring 55 abuts against the protrusion at the lower end of the control rod 41. The design of the second spring 55 can provide power for the subsequent resetting of the push plate 54. At the same time, a slide groove is provided inside the push plate 54. The design of the slide groove can prevent the protrusion at the lower end of the control rod 41 from escaping from the restriction of the push plate 54, so that the push plate 54 and the protrusion at the lower end of the control rod 41 will not separate. The push plate 54 is located between the scraper 52 and the glue spraying nozzle 51, and the push plate 54 is slidably connected to one side of the scraper 52. A resisting rod 56 is provided on one side of the push plate 54. At the same time, through such a design, the push plate 54 can push down the glue adhering to the scraper 52 during the downward sliding process, preventing excessive glue from adhering to the scraper 52, thereby reducing the waste of glue to a certain extent.

[0039] Both ends of one side of the scraper 52 are provided with a resistance bevel block 53, which is used to resist the resistance rod 56. Through the design of the resistance bevel block 53, when the push plate 54 slides to the bottom of the scraper 52 and drives the resistance rod 56 to contact the resistance bevel block 53, the push plate 54 can slide under the action of the resistance bevel block 53.

[0040] A sliding groove 11 is provided on the inner side of the fixing frame 1, and the sliding groove 11 is slidably connected to the sliding plate 12. A fixing block 14 is provided on the other side of the sliding plate 12, and the fixing block 14 is used to engage with the limiting block 15. Through the design of the fixing block 14 and the limiting block 15, the limiting block 15 bonded with the composite plate 16 can be connected to the fixing block 14, which can reduce the shaking of the limiting block 15 and the composite plate 16 during the detection process to a certain extent, thereby increasing the accuracy of the detection result.

[0041] When the control rod 41 slides downward, the push plate 54 at the lower end of the control rod 41 will slide downward together. The push plate 54 can push the glue adhering to the scraper 52 off the scraper 52 by sliding downward. As the push plate 54 continues to slide downward, Figure 4 As shown, when one end of the resistance rod 56 on the push plate 54 contacts the wavy round block on the resistance inclined block 53, under the guidance of the wavy round block on the resistance inclined block 53, the push plate 54 slides laterally away from the scraper 52 and also causes the push plate 54 to shake. At this time, the sliding ball 4 is in the straight sliding groove 33, and the second spring 55 is deformed while the push plate 54 slides. Through the design of the second spring 55, when the subsequent control rod 41 drives the push plate 54 to slide upward, under the action of the second spring 55, the push plate 54 is driven to contact one side of the scraper 52 again; it should be noted that even if the push plate 54 drives the resistance rod 56 to slide downward to the maximum distance, the resistance rod 56 will not slide over the resistance inclined block 53.

[0042] As the rotating tube 22 continues to rotate, when the sliding ball 4 slides from the straight slide groove 33 into the lower end of the vertical part of the first wave slide groove 34, the first spring 43 can drive the control rod 41 to slide upward quickly, so that the sliding ball 4 slides from the lower end of the vertical part of the first wave slide groove 34 to the upper end. Through the design of the vertical groove of the first wave slide groove 34, when the sliding ball 4 slides into the vertical groove of the first wave slide groove 34, the first spring 43 can drive the control rod 41 and the sliding ball 4 to slide upward quickly through the vertical groove. The design of the vertical groove of the first wave slide groove 34 will not affect the sliding of the sliding ball 4. Through the rapid upward sliding of the sliding ball 4, the sliding ball 4 hits one end of the vertical groove of the first wave slide groove 34, thereby making the sliding ball 4, the control rod 41 and the push plate 5 4 vibration, through the vibration to make the glue on the push plate 54 is shaken off, so that the glue will not stick to the push plate 54, at this time the sliding column 44 is in the vertical slide groove 210, through the design of the vertical slide groove 210, the control rod 41 in the process of rapid upward sliding will not affect the sliding of the sliding column 44, can reduce the control rod 41 rebound friction, at the same time by the sliding column 44 in the vertical slide groove 210 sliding, so that the sliding column 44 will not slide into the inclined groove 29, so that the position of the control block 28 will not deviate, so that the glue spray head 51 can stably apply glue; the rotating tube 22 continues to rotate, when the sliding ball 4 slides from the first wave slide groove 34 into the vertical part of the second wave slide groove 35, the push plate 54 is bounced again, so that the glue adhered to the push plate 54 is bounced again, at the same time, Figure 6 As shown, the vertical part of the first wave chute 34 is longer than the vertical part of the second wave chute 35. Through such a design, after the push plate 54 bounces off the glue for the first time, the glue has a certain thickness, so that the sliding ball 4 slides at the inclined part of the first wave chute 34, driving the push plate 54 to continue to push downward without making the push plate 54 contact with the glue again, so that when the push plate 54 bounces the glue for the second time, the glue adhering to the push plate 54 can be bounced off more cleanly.

[0043] After the glue is evenly applied on the composite board 16, the composite board 16 and the limiting block 15 are bonded together so that the limiting block 15 can be firmly adhered to the composite board 16. Figure 1 Then, the limiting block 15 is connected to the fixed block 14 , and the sliding plate 12 is pulled to slide in the sliding groove 11 by the hydraulic rod 13 , so that the fixed blocks 14 at both ends stretch the composite plate 16 .

[0044] In this embodiment: by sliding the push plate 54 transversely and shaking it at the same time, the push plate 54 is moved away from the scraper 52, so that the glue can be evenly spread and will not gather on one side of the scraper 52. At the same time, the glue on the push plate 54 can be shaken off by the shaking of the push plate 54, so as to prevent the glue from sticking to the push plate 54. It can also increase the contact area between the glue and the composite plate 16 to a certain extent, and can also make the glue be spread more evenly. At the same time, by bouncing the push plate 54, the glue sticking to the push plate 54 can be bounced onto the composite plate 16, so that the glue can be smeared on the composite plate 16, so that the glue can be further evenly spread on the composite plate 16, so as to prevent the composite plate 16 and the limiting block 15 from being separated in some areas due to insufficient bonding force during the stretching process, so that the test result is more accurate. Moreover, the push plate 54 is used to push the glue attached to the scraper 52 down, and the vertical part of the first wave chute 34 is longer than the vertical part of the second wave chute 35, so that the push plate 54 will not contact the glue bounced off for the first time when it bounces for the second time, so that the glue on the push plate 54 can be bounced off more cleanly, which can reduce the waste of glue to a certain extent.
