Description

Technical Field

[0001] The present invention relates to the technical field of stretching detection equipment, and in particular to a black tape anti-stretching detection device. Background Art

[0002] As a bonding material with diverse functions and wide applications, the performance and uses of black tape vary significantly due to differences in material composition, production process, and structural design. In practical applications, the mechanical properties of black tape, especially the anti-tensile strength, are one of the important indicators for evaluating its quality and applicability. Therefore, it is of great significance to accurately detect its anti-tensile performance.

[0003] Currently, in the prior art, the commonly used detection equipment is mostly a general-purpose tensile testing machine. Although such equipment has good test accuracy and wide applicability, there are still many deficiencies when specifically applied to the detection of black tape. First of all, such equipment usually only has one clamping mechanism, resulting in only a single sample being tested each time. This single test mode not only has low efficiency, but also requires the black tape samples to be cut and pretreated one by one before testing. The operation process is cumbersome and time-consuming, increasing the possibility of manual intervention, and thus introducing human errors, which affect the consistency and accuracy of the test results.

[0004] In addition, due to the single-sided adhesive structure of black tape (i.e., one side is coated with an adhesive layer), when using traditional fixtures for clamping, it is very easy for the sample to slide or even fall off, thereby affecting the stability and reliability of the test data. Although some fixture surfaces are provided with anti-slip patterns or grooves to enhance the clamping force, due to the uneven distribution of the adhesive on the tape surface and the difficulty in effectively controlling the clamping pressure, it is still difficult to fundamentally solve the problem of slipping.

[0005] In view of the above technical defects, it is necessary to design a black tape anti-stretching detection device, which should have the function of multi-station synchronous testing, reduce the sample cutting and pretreatment steps, and improve the detection efficiency; at the same time, adopt a more stable clamping structure to effectively prevent the black tape from slipping or falling off during the test, and improve the reliability of the test data.

Detailed implementation manners

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be noted that the orientation terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0028] Embodiment: A black tape anti-tensile detection device, as Figures 1 - 5 shown, includes: A frame 1, which is the main load-bearing and supporting carrier of the device; A clamping and stretching part 2. The clamping and stretching part 2 includes extension frames 21 symmetrically arranged on the front side of the frame 1 on the left and right. Electric push rods 22 are fixedly installed on the extension frames 21. Fastening plates 23 are connected to the telescopic ends of the two electric push rods 22. Cylinders 24 with telescopic ends facing down are arranged on the tops of the fastening plates 23. Clamping plates 25 are fixedly arranged on the telescopic ends of the cylinders 24. The telescopic movement of the cylinders 24 can drive the connected clamping plates 25 to move up and down. The clamping plates 25 have protruding ends distributed at intervals, which are used to enhance the fitting effect during clamping; The transmission part 3 for batch conveying the black tape body 100 to be detected. The transmission part 3 includes side plates 31 fixedly arranged on the left and right sides of the frame 1. A chain transmission assembly 32 is also installed around the frame 1. The chain transmission assembly 32 is a prior art and consists of a driving part (such as a driving motor) and a chain transmission mechanism for realizing circular conveying, which will not be elaborated here. Partition plates 33 are arranged at intervals on the chain of the chain transmission assembly 32. Moving plates 34 are symmetrically and slidably arranged inside the left and right of the partition plates 33. Clamping blocks 35 slidably connected to the same side plate 31 are arranged at the ends of the moving plates 34. Pressure sensors are arranged on the clamping blocks 35. The clamping blocks 35 are snap-connected to the snap plates 23 on the same side. And fitting frames 36 are slidably embedded in the clamping blocks 35 at intervals. The layout of the fitting frames 36 is adapted to the protruding ends of the clamping plates 25 on the same side. And an elastic member 37 is arranged between the fitting frames 36 and the inner walls of the corresponding clamping blocks 35. In this embodiment, the elastic member 37 is a spring, providing necessary elastic support for the fitting frames 36 to reset and move.

[0029] Furthermore, through the coordinated setting between the clamping and stretching part 2 and the transmission part 3, the chain transmission assembly 32 drives the partition plates 33 to run in a cycle, realizing the continuous and orderly conveying of the black tape body 100, significantly improving the automation degree and working efficiency of the device, making the detection process more batch-oriented, and being applicable to the high-efficiency tensile resistance performance detection of multiple batches of black tape bodies 100.

[0030] During the clamping process, an uneven fitting structure is formed between the clamping plate 25 and the clamping block 35 through the protruding end and the fitting frame 36, thereby enhancing the clamping stability, effectively reducing the risk of the black tape body 100 slipping during the clamping process, and further ensuring the accuracy and repeatability of the detection data. In addition, due to the design of the fitting frame 36 being slidably embedded and cooperating with the elastic member 37, the self-adaptive switching of the clamping surface of the clamping block 35 can be realized during the clamping and releasing processes, enabling it to flexibly switch between the planar state and the uneven fitting state, not only meeting the clamping requirements but also facilitating subsequent cleaning treatment, and improving the applicability and maintenance efficiency of the device.

[0031] To simplify the pretreatment process, the device adopts a "tear and stick" feeding method: after directly pulling out and unfolding the black tape body 100 from the film, adhering it between the clamping blocks 35 can complete the assembly operation, without additional cutting or positioning treatment, realizing "ready to use immediately", and further improving the operation convenience and overall detection efficiency.

[0032] Such as Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown in the figure, it further includes a cleaning part 4 for removing the attached residual glue. The cleaning part 4 includes an assembly frame 41 arranged at the bottom of the frame 1. A hot air blower 44 is installed on the assembly frame 41. A first spray pipe 45 and a second spray pipe 46 are connected to the air outlet of the hot air blower 44. Both the first spray pipe 45 and the second spray pipe 46 are located inside the assembly frame 41, so that the first spray pipe 45 and the second spray pipe 46 can spray hot air towards the clamping block 35 to soften the attached colloid. And inclined blades 48 that are in contact and cooperation with the clamping block 35 are arranged at intervals before and after between the inner walls of the assembly frame 41. The blades of the inclined blades 48 are designed with different inclination angles to better fit the clamping surface of the clamping block 35. In this way, the inclined blades 48 can effectively scrape off the residual colloid softened by the hot air, realizing efficient cleaning operations.

[0033] Particularly, during the rotation process, the fitting frame 36 of the clamping block 35 is in a non-compressed state, so that the clamping surface is restored to a flat surface, making it easier to clean, improving the cleaning efficiency, and simplifying the cleaning process.

[0034] As Figure 6 and Figure 7 shown in the figure, the cleaning part 4 further includes a filter pipe 47 connected to the air inlet of the hot air blower 44. The tail end of the filter pipe 47 is connected to the assembly frame 41 to form a closed air circulation state. And a guide plate 49 is arranged at the rear side of the assembly frame 41 for guiding the scraped residual glue to be discharged, ensuring that the waste does not accumulate and affect subsequent operations.

[0035] As Figure 6 and Figure 7 shown in the figure, it further includes convex rods 411 symmetrically arranged on the left and right at the rear end of the assembly frame 41. A closing frame 42 is hingedly arranged at the rear through hole of the assembly frame 41. On the closing frame 42, limit plates 43 that are symmetrically rotated left and right and are buckled and connected to the convex rods 411 on the same side are arranged, which is convenient for regularly opening the closing frame 42 for maintenance or emptying the waste.

[0036] As Figure 1 and Figure 8 shown in the figure, it further includes a cutting part 5. The cutting part 5 includes inclined frames 51 symmetrically arranged on the left and right at the top of the frame 1. The inclined frames 51 present an included angle structure with an opening facing the rear. And cutting knives 52 are arranged on the inclined frames 51, so that the cutting knives 52 are arranged in an inclined state. On the left and right sides of the frame 1, a leakage frame 53 for guiding the cut tape to be discharged is respectively arranged.

[0037] Furthermore, by using the design of the included angle with an opening facing the rear of the inclined frame 51, the black tape body 100 can naturally adhere to the cutting knife 52 during the conveying process, and the cutting knife 52 is installed at an inclined angle, which is more in line with the stress trend of the movement direction of the black tape body 100 during conveying, helping to achieve smooth and continuous cutting actions, thereby improving the cutting efficiency and quality.

[0038] AsFigure 1 , Figure 8 and Figure 9 As shown, it also includes a separation part 6, which includes attachment tubes 61 respectively arranged at the lower ends of the extension frames 21 on both sides, there is a gap between the attachment tubes 61 on both sides, and an eccentrically arranged driving shaft 63 passes through and rotates between the attachment tubes 61, the driving shaft 63 is located at an upper position, and a motor 62 whose output end is connected to the end of the driving shaft 63 is installed on one side of the extension frame 21, and a toggle frame 64 located between the attachment tubes 61 on both sides is arranged in the middle of the driving shaft 63, and a branch end of the toggle frame 64 is provided with a bending section for fitting the black tape body 100 after hooking and detection.

[0039] Specifically, since the driving shaft 63 adopts an eccentric structure, the branch ends of the toggle frame 64 produce periodic displacement changes relative to the attachment tube 61 during the rotation process. When the toggle frame 64 rotates downward, its branch ends are gradually embedded between the attachment tubes 61 on both sides, and the black tape body 100 attached thereto is adhered to the surface of the attachment tube 61, thereby realizing the automatic peeling of the black tape body 100 after detection; and when the toggle frame 64 rotates upward, its branch ends gradually detach from the area between the attachment tubes 61 and are exposed, so as to contact and hook the new black tape body 100 to be peeled off, completing a new round of peeling cycle.

[0040] In addition, the branch end of the toggle frame 64 is in a bent state, which can better fit the black tape body 100, ensure stable hooking and effective peeling of the black tape body 100 during rotation, reduce manual intervention, and improve the overall degree of automation and operating efficiency.

[0041] like Figure 8 and Figure 9 As shown, it also includes horizontal plates 65 respectively arranged on the extension frame 21, and a U-shaped guide frame 66 is arranged between the horizontal plates 65 on both sides. The U-shaped guide frame 66 is designed to be open toward the rear, and the upper end of the U-shaped guide frame 66 passes through between the partition plate 33 and the corresponding black tape body 100, and is used to limit and guide the black tape body 100; the lower end of the U-shaped guide frame 66 is provided with a slot allowing the branch of the toggle frame 64 to pass through, so as to ensure that the toggle frame 64 can pass smoothly during the rotation process and complete the peeling operation of the black tape body 100.

[0042] When in use, first ensure that the device is placed stably, and then prepare the batch of black tape film to be tested. Then pull the black tape body 100 out of the film and unfold it, and make the black tape body 100 and the film stick together between the two clamping blocks 35 of the rear partition plate 33, and the film is placed outside the clamping block 35. Synchronously open the chain conveying assembly 32 to make its chain run, drive the partition plate 33 and the components thereon to be transported from the back to the front, and repeat the above operation, so as to realize the sequential loading of the black tape body 100 in accordance with the overall conveying trend of the device.

[0043] After loading, the black tape body 100 moves forward step by step with the conveyor until it reaches the cutting section 5. Since the inclined frame 51 has an angular structure with an opening facing backward, the black tape body 100 will gradually approach the cutting knife 52 above it during the process of approaching the inclined frame 51, and thus be cut and separated by the cutting knife 52. The separated film rolls will then fall into the leakage frame 53 and be discharged, completing the cutting operation of the black tape body 100.

[0044] As the conveyor continues to operate, the clamping block 35 gradually approaches the clamping and stretching section 2. At this time, the clamping block 35 disengages from the side plate 31 along the direction and forms a snap connection with the snap plate 23 on the same side. Then, the conveyor is stopped, and the air cylinder 24 is activated, causing its telescopic end to extend, driving the connected clamping plate 25 to move downward until the clamping plate 25 fits against the clamping block 35. Under the action of the protruding end of the clamping plate 25, the fitting frame 36 is pressed and slides downward, and the elastic member 37 deforms accordingly, causing the clamping surface of the clamping block 35 to form a depression adapted to the protruding end of the clamping plate 25, thereby achieving a concave-convex fit to firmly fix the end of the black tape body 100 placed therein, and the two sides cooperate to clamp to further stabilize the detection position of the entire black tape body 100.

[0045] After the clamping is completed, the electric push rods 22 on both sides are activated, causing their telescopic ends to shorten, pulling the snap plates 23 on both sides to move outward, thereby driving the clamping blocks 35 to open to both sides, and the moving plate 34 slides along the partition plate 33 synchronously, so as to apply a tensile force to the black tape body 100 for tensile resistance performance detection. At the same time, the pressure sensors on the clamping blocks 35 collect data in real time and feedback it to the background, achieving the tensile resistance detection of the black tape body 100.

[0046] After the detection is completed, the electric push rod 22 and the air cylinder 24 are reset, so that the moving plate 34 and the clamping block 35 return to their original positions, the clamping plate 25 disengages from the clamping block 35, the fitting frame 36 is released from the limit, and the elastic member 37 is reset, causing the clamping surface of the clamping block 35 to return to a flat state. Subsequently, the conveyor is restarted, and the stretched black tape body 100 continues to be conveyed forward. When passing through the U-shaped guiding frame 66, the upper end of the U-shaped guiding frame 66 will be embedded between the black tape body 100 and the partition plate 33.

[0047] When the stretched black tape body 100 is conveyed to the front end of the device and enters the rotating area, the black tape body 100 is located at the bottom of the frame 1. At this time, the motor 62 is turned on, the drive shaft 63 rotates, and drives the toggle frame 64 to rotate. The toggle frame 64 passes through the lower notch of the U-shaped guide frame 66 and toggles the black tape body 100 that has moved here, causing it to fall off and adhere to the branch end of the toggle frame 64. As the toggle frame 64 continues to rotate, since it is eccentrically arranged with the attachment cylinder 61, the branch end attached with the black tape body 100 is inserted between the two attachment cylinders 61, causing the black tape body 100 to bend and conform to the surface of the attachment cylinder 61. Finally, with the further rotation of the toggle frame 64, it detaches from the toggle frame 64 and adheres to the attachment cylinder 61, completing the peeling operation of the black tape body 100 after tensile detection.

[0048] Subsequently, the used clamping block 35 is conveyed and moved into the interior of the assembly frame 41. The hot air blower 44 starts to work, spraying hot air bidirectionally through the first nozzle 45 and the second nozzle 46 to soften the residual colloid on the surface of the clamping block 35. Then the clamping block 35 moves to the inclined blade 48, and the residual colloid is scraped off through the fitting contact. At this time, the clamping surface of the clamping block 35 is in a flat state, which is more conducive to cleaning, achieving the purpose of efficiently removing the residual glue.

[0049] Finally, the turning limit plate 43 is turned to disengage from the convex rod 411, the closing frame 42 is opened, and the scraped residual glue is discharged through the guiding of the guiding plate 49. The entire process completes a cycle, realizing the batch and integrated pretreatment operation of the black tape detection process.

[0050] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
