Description

Technical Field

[0001] This invention relates to the field of cured adhesive recycling technology, and in particular to a cured adhesive recycling device. Background Technology

[0002] In production or equipment debugging, dummy shot dispensing is frequently used. The cured adhesive is dripped directly into the receiving bottle by a dispensing pump. When the adhesive reaches the bottleneck, it is discarded, resulting in a waste of cured adhesive resources. When a certain amount remains in the dispensing tube, to prevent the risk of dispensing failure, the adhesive is replaced prematurely, which also leads to resource waste. Summary of the Invention

[0003] To address the shortcomings in the aforementioned background technology, this invention proposes a cured adhesive recycling device, which solves the problem of insufficient cured adhesive recycling and waste caused by existing technologies.

[0004] The technical solution of the present invention is implemented as follows: a cured adhesive recycling device includes a dispensing mechanism, an adhesive receiving mechanism, and a defoaming support mechanism arranged sequentially from top to bottom; the adhesive receiving mechanism includes an adhesive receiving bottle and a support frame for supporting the adhesive receiving bottle; the defoaming support mechanism includes an adapter bottle and a bottle carrier for supporting the adapter bottle, and the adhesive receiving bottle and the adapter bottle are connected by a guide tube.

[0005] Furthermore, the upper part of the glue-receiving bottle has a wide-mouth structure, and the inner bottom of the glue-receiving bottle has a sloping structure, with the sloping structure inclined towards the guide port; the guide port is located on the side wall of the lower part of the glue-receiving bottle. Preferably, the bottle body of the glue-receiving bottle has a UV-protective function.

[0006] Furthermore, the bottle carrier includes a support base, on which a rotatable disc is provided. The disc is connected to a drive motor mounted on the support base via a transmission mechanism. The disc is provided with positioning holes for fixing the adapter bottle.

[0007] Preferably, a protective pad is provided inside the positioning hole; the positioning hole is a vertical hole or an oblique hole, and the positioning holes are distributed on a circle with the center of the plate as the center, and the inclination angle of the oblique hole is 10~60°.

[0008] Furthermore, the transmission mechanism includes a driven gear disposed at the bottom of the disc base and a driving gear disposed at the output end of the drive motor. The driving gear meshes with the driven gear and drives the disc base to rotate under the action of the drive motor.

[0009] Furthermore, the flow guide includes an inlet flow guide and an outlet flow guide, which are connected by a rotary joint. The inlet end of the inlet flow guide is connected to the glue bottle, and the outlet end of the outlet flow guide is connected to the adapter bottle.

[0010] The rotary joint is connected to the lower part of the support frame and located directly above the bottle holder; the number of inlet guide tubes is not less than the number of outlet guide tubes.

[0011] Preferably, the inlet end of the liquid inlet guide tube is provided with a connecting cap I that is compatible with the glue bottle, and the outlet end of the liquid outlet guide tube is provided with a connecting cap II that is compatible with the matching bottle.

[0012] Furthermore, the dispensing mechanism includes a connecting frame, on which a dispensing tube is clamped, and the dispensing tube corresponds one-to-one with the dispensing bottle.

[0013] The beneficial effects of this invention are as follows: By coordinating the adhesive dispensing mechanism and the defoaming support mechanism, this invention achieves efficient recovery of cured adhesive, ensuring that the recovered adhesive is fully usable for equipment debugging or for sampling and testing in other processes; effectively improving material utilization and reducing production costs. The adhesive dispensing mechanism of this invention is flexible; during equipment debugging or resumption of production after a shutdown, the cured adhesive is first dispensed through the dispensing mechanism for several tens of seconds, then rotated to the top of the product for further dispensing, preventing adhesive breakage and improving product quality. The defoaming support mechanism of this invention achieves efficient adhesive defoaming by controlling the rotation speed. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1 As shown, a cured adhesive recycling device includes a dispensing mechanism 1, an adhesive receiving mechanism 2, and a degassing support mechanism 3 arranged sequentially from top to bottom. In actual use, the dispensing mechanism is installed on the dispensing equipment to hold the adhesive tube; specifically, the dispensing mechanism 1 includes a connecting frame 11, which holds the adhesive tube 12, with each adhesive tube 12 corresponding to an adhesive receiving bottle 21. The adhesive receiving mechanism 2 includes an adhesive receiving bottle 21 and a support frame 22 for supporting the adhesive receiving bottle 21. The support frame can support multiple adhesive receiving bottles 21 simultaneously as needed to receive the adhesive dripping from the adhesive tube. The degassing support mechanism 3 includes an adapter bottle 31 and a bottle carrier 32 for supporting the adapter bottle 31. Multiple adapter bottles 31 can be supported simultaneously on the bottle carrier 32 as needed. The receiving bottle 21 and the adapter bottle 31 are connected by a flow guide tube 4. The adapter bottles 31 on the bottle carrier 32 can be degassed under rotation, expelling air bubbles from the adhesive within the adapter bottle 31, effectively completing the adhesive filling. The flow guide tube 4 can be designed to support multiple adapter bottles as needed, ensuring that the adhesive in the receiving bottle 21 flows smoothly and efficiently into the adapter bottle 31, improving recycling efficiency.

[0023] As a preferred embodiment, such as Figure 2 As shown, the upper part of the glue receiving bottle 21 has a wide-mouth structure, which facilitates the receipt of glue flowing from the glue tube. The inner bottom of the glue receiving bottle 21 has a sloping structure, and the sloping structure is inclined towards the guide port 23; the guide port 23 is located on the lower side wall of the glue receiving bottle 21. The above-mentioned sloping design facilitates the smooth flow of glue. In this embodiment, the bottle body of the glue receiving bottle 21 has a UV-resistant function; preferably, a black bottle body can be used to effectively prevent ultraviolet rays from irradiating the glue inside the bottle and ensure the quality of the glue.

[0024] Example 2

[0025] like Figure 3As shown, based on Embodiment 1, the bottle carrier 32 includes a support base 32-1, on which a rotatable disc 32-2 is provided. The disc 32-2 is connected to a drive motor 32-3 provided on the support base 32-1 via a transmission mechanism. The disc 32-2 is provided with positioning holes 32-4 for fixing the adapter bottle 31. The number of positioning holes can be set multiple as needed. They are distributed on a circle with the center of the disc 32-2 as the center, and the positioning holes 32-4 are vertical holes or oblique holes. In this embodiment, the transmission mechanism includes a driven gear provided at the bottom of the disc 32-2 and a driving gear provided at the output end of the drive motor 32-3. The driving gear meshes with the driven gear, driving the disc 32-2 to rotate under the action of the drive motor.

[0026] As one solution in this embodiment, such as Figure 5 As shown, the positioning hole 32-4 is a vertical hole design. By controlling the rotation speed of the drive motor to control the plate 32-2, the adhesive liquid is tilted to defoam.

[0027] Example 3

[0028] Based on Example 2, such as Figure 4 As shown, a protective pad 32-5 is provided inside the positioning hole 32-4. The protective pad can be made of an elastic rubber sleeve, which can both position the adapter bottle and protect it, ensuring that the adapter bottle remains relatively stationary during the rotation of the plate.

[0029] To ensure minimal air bubbles flow into the adapter bottle 31, the positioning hole 32-4 is an angled hole. In this case, the adapter bottle 31 is tilted, and the adhesive flows slowly along its inner wall. When multiple angled holes are provided, they are distributed on a circle centered on the center of the disc base 32-2. The angle of the angled holes is 10~60°. It should be noted that the angle of the angled hole refers to the angle between the adapter bottle and the plane of the disc base in the direction towards the center of the disc base; preferably, the angle is 10~30°, tilted towards the center. In this case, the adapter bottle 31 within the angled hole is tilted, reducing the amount of air bubbles in the adhesive. When air bubbles remain in the adapter bottle 31, the disc base rotates it 360° at high speed, concentrating the adhesive to one side through centrifugal force, thus achieving a degassing effect.

[0030] Example 4

[0031] Based on Embodiment 2, the flow guide 4 includes an inlet flow guide 41 and an outlet flow guide 42, which are connected by a rotary joint 43. When two or more adapter bottles are mounted on the bottle holder, the rotary joint is used for connection, which avoids interference of the flow guides caused by the rotation of the plate holder and ensures that the other adapter bottle can be properly connected to the adhesive, thus improving the adhesive recovery efficiency. The inlet end of the inlet flow guide 41 is connected to the adhesive receiving bottle 21, and the outlet end of the outlet flow guide 42 is connected to the adapter bottle 31. The adhesive in the adhesive receiving bottle flows into the rotary joint 43 through the inlet flow guide 41, then into the outlet flow guide 42 through the rotary joint, and finally into the adapter bottle 31 through the outlet flow guide 42. When one of the adapter bottles 31 needs to be defoamed, the connection between the adapter bottle 31 and the liquid outlet guide tube 42 can be disconnected, and the disc base can be rotated to drive the adapter bottle 31 to rotate at high speed, thereby achieving defoaming of the adhesive.

[0032] In this embodiment, the rotary joint 43 is connected to the lower part of the support frame 22 and located directly above the bottle holder 32, ensuring the efficient operation of the rotary joint; the number of inlet guide tubes 41 is not less than the number of outlet guide tubes 42. Specifically, four glue-receiving bottles and two adapter bottles can be selected, which corresponds to two inlet guide tubes 41 and two outlet guide tubes 42, realizing a one-to-many structure design for the guide tube fittings and improving the efficiency of glue receivable and recycling.

[0033] For ease of connection, the inlet end of the liquid inlet guide tube 41 is equipped with a connecting cap I 44 that is compatible with the receiving bottle 21; the connecting cap I 44 can be designed as an integral part of the liquid inlet guide tube 41 to ensure airtightness. The outlet end of the liquid outlet guide tube 42 is equipped with a connecting cap II 45 that is compatible with the adapter bottle 31. The connecting cap II 45 can be designed as an integral part of the liquid outlet guide tube 42 to ensure airtightness.

[0034] During use, one end of the guide tube is connected to the receiving bottle, and the other end is connected to the adapter bottle with a sealing rubber ring on top. This prevents the adhesive from coming into contact with external gases. The adhesive in the tube flows from the receiving bottle into the adapter bottle, where it undergoes degassing. This structural design enables efficient recycling of the cured adhesive, saving approximately 20g of adhesive per adhesive change cycle, effectively improving material utilization and reducing production costs.

[0035] The degassing process is as follows: The bottle carrier is activated, and the tray rotates the adapter bottle 31 at high speed, thus degassing the adhesive. To ensure that the collected adhesive is sufficient for equipment debugging or for sample testing in other processes, a tensile test is performed on the collected adhesive. The data is as follows:

[0036] Among them, Sample 1 was not degassed, and the positioning hole 32-4 was designed as a vertical hole. Samples 2-4 were degassed. The positioning hole 32-4 in Sample 2 was designed as a vertical hole. The inclination angle of the positioning hole 32-4 in Sample 3 was 10°. The inclination angle of the positioning hole 32-4 in Sample 4 was 30°. The inclination angle of the positioning hole 32-4 in Sample 5 was 60°.

[0037]

[0038] Stick the collected glue on the dispensing area of the upper and lower covers of the screen body. After compression encapsulation, test the influence of the collected glue on the adhesion of the screen body. The specific operation process is as follows:

[0039] 1. The substrate surface of the screen body faces upward;

[0040] 2. Use double-sided tape to stick the encapsulation cover to the bonding plate, align the edge of the encapsulation cover surface with the edge of the bonding plate, and expose the lead area;

[0041] 3. Fix the bonding plate with the screen body on the tensile machine platform;

[0042] 4. Fix the test fixture on the tensile machine fixture, and note that the bottom end needs to be close to the lead area;

[0043] 5. Turn on the tensile machine for testing. After the upper and lower covers of the screen body are peeled off, record the maximum tensile force during the test as the adhesion force of this screen body, which is the test value of the sample.

[0044] The standard value of the above glue is 29.5N. The sample glue corresponding to the test value greater than this standard value is the qualified glue. As can be seen from the above table, the qualified rate of the glue collected in the present invention is 100%. Therefore, the collected glue fully meets the equipment debugging or is used for proofing tests in other workshops.

[0045] Furthermore, as can be seen from the above table, degassing the glue can significantly improve the adhesion of the screen body. This is because after degassing, the bubbles in the glue can be effectively removed, so that the distribution area of the glue in the screen body is large, and the adhesion between the upper and lower substrates of the screen body is more effectively enhanced.

[0046] Judging from the setting method of the positioning hole, the lower the inclination angle of the positioning hole, the stronger the adhesion of the test screen body. This is because the lower the inclination angle, the increased surface area for releasing bubbles, and the better the effect during the degassing process, thereby effectively improving the adhesion between the upper and lower covers of the screen body. Specifically, the inclination angle of the positioning hole is 10-60°. If the inclination angle of the positioning hole is less than 10°, it will lead to a small number of positioning holes distributed on the disc base and low collection rate. If the inclination angle of the positioning hole is greater than 60°, it will lead to poor degassing effect, and the screen body will have a glue breakage phenomenon during dispensing, reducing the adhesion of the screen body.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
