Description

Technical Field

[0001] This utility model relates to the field of double-sided adhesive bonding, specifically a device for controlling the uniformity of double-sided adhesive bonding thickness. Background Technology

[0002] In modern industrial production, double-sided tape, as an important adhesive material, is widely used in electronics, automobiles, packaging, construction, and many other fields. The adhesion quality of double-sided tape, especially the uniformity of its thickness, directly affects the performance, appearance, and lifespan of products. For example, in the assembly process of electronic products, double-sided tape is used to fix electronic components. If the adhesion thickness is uneven, it may lead to poor contact between the components and the circuit board, thus affecting the electrical performance and reliability of the product. However, in actual production, due to various factors such as variations in the properties of double-sided tape materials, instability of the transmission mechanism, and differences in operator skills, it is often difficult to maintain a uniform adhesion thickness. This not only increases the defect rate and production costs but may also seriously affect the overall quality of the product. Currently, there is no device to detect the thickness of double-sided tape before processing; it is only checked during use to determine if the thickness is acceptable. Therefore, it is necessary to test the thickness of double-sided tape before its official use. To address this, we have proposed a double-sided tape adhesion thickness uniformity control device. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-3 A double-sided adhesive thickness uniformity control device, comprising:

[0025] Base 1;

[0026] Two sets of side plates 2 are fixedly installed on the top of the base 1. A pair of rotating rollers 3 are rotatably installed between the two sets of side plates 2. The outer walls of the pair of rotating rollers 3 are fitted with double-sided adhesive transfer discs 4 for transferring double-sided adhesive.

[0027] The component rod 5 is fixed between the two sets of side plates 2. The outer wall of the component rod 5 is fitted with a bottom transmission roller 7, and a movable transmission roller 11 is provided above the component rod 5.

[0028] A double-sided adhesive thickness detection component is installed on component rod 5.

[0029] Both the bottom conveyor roller 7 and the movable conveyor roller 11 are cylindrical.

[0030] Inclined transmission guide plates 17 are fixedly connected to both sides of the corresponding component rod 5 between the two sets of side plates 2.

[0031] The two sets of transmission guide boards 17 are set in a mirror image.

[0032] The double-sided adhesive thickness detection component includes a baffle 6, uprights 8, fixed plates 9, movable rods 10, and opening slots 12. Two sets of uprights 8 are fixedly installed on the top of the component rod 5. Fixed plates 9 are fitted on the outer walls of the two sets of uprights 8 at their respective middle positions. Vertical baffles 6 are fitted between the two ends of the bottom transmission roller 7 on the outer walls of the component rod 5 and the two sets of uprights 8. Opening slots 12 penetrating both sides of the baffles 6 are opened in the middle of the two sets of baffles 6. Movable rods 10 are slidably fitted between the two sets of uprights 8 and the two sets of baffles 6.

[0033] The movable conveyor roller 11 is sleeved on the outer wall of the movable rod 10 and located between the two sets of baffles 6.

[0034] The double-sided tape thickness detection assembly also includes a top plate 13, an alarm call device 14, and an alarm rod 15. The top plate 13 is fixedly connected between the two sets of baffles 6 near the top position. An inverted alarm call device 14 is fixedly installed at the bottom of the top plate 13. An alarm rod 15 is fixedly installed on the top of the movable transmission roller 11 directly below the alarm call device 14.

[0035] The top of the alarm lever 15 fits tightly against the bottom of the alarm call device 14. A button for operating the alarm call device 14 is fixed to the bottom of the device. Taking electronic product assembly as an example, uneven thickness of double-sided adhesive can lead to poor contact between components and circuit boards, affecting electrical performance and reliability. This device detects the thickness of the double-sided adhesive to ensure uniform thickness, providing qualified double-sided adhesive for subsequent product assembly processes. This helps guarantee product performance, appearance, and lifespan, improving overall product quality. When the double-sided adhesive thickness is too large, the movable transmission roller 11 slides upwards with the thickness of the adhesive, and then rises on the upright 8 via the movable lever 10. As the movable transmission roller 11 rises, the alarm lever 15 presses against the alarm call device 14, causing it to sound an alarm. This allows staff to promptly identify which location on the double-sided adhesive exceeds the normal thickness, facilitating subsequent handling of problematic double-sided adhesive and improving the efficiency and accuracy of problem handling.

[0036] Guide plates 16 for guiding the double-sided adhesive are fixedly connected to the top of the bottom transfer roller 7 near both ends. Two sets of mirror-arranged inclined transfer guide plates 17 guide the double-sided adhesive, allowing it to slide smoothly between the bottom transfer roller 7 and the movable transfer roller 11. This ensures stable transfer of the double-sided adhesive during the detection process. At the same time, the guide plates 16 fixedly connected to the top of the bottom transfer roller 7 near both ends further guide the position of the double-sided adhesive, preventing it from shifting and thus ensuring the accuracy of the double-sided adhesive thickness detection.

[0037] Working principle: During use, the double-sided tape is transported through two sets of double-sided tape transfer discs 4, and two sets of transfer guide plates 17 guide the double-sided tape, causing it to slide between the bottom transfer roller 7 and the movable transfer roller 11. When the thickness of the double-sided tape is normal, it passes normally between the bottom transfer roller 7 and the movable transfer roller 11. When the thickness of the double-sided tape is too large, the movable transfer roller 11 slides upward with the thickness of the double-sided tape. During the sliding process, the movable transfer roller 11 is raised upward on the two sets of uprights 8 via the movable rod 10. The alarm rod 15 is pressed against the alarm call device 14 as the movable transfer roller 11 is raised, and the button at the bottom of the alarm call device 14 is pressed upward, thereby causing the alarm call device 14 to sound an alarm, so that the staff can know which part of the double-sided tape has a thickness that exceeds the normal value. When the double-sided tape slides at the top of the bottom transfer roller 7, the two sets of guide plates 16 guide the position of the double-sided tape to prevent the position of the double-sided tape from shifting.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
