[0024] Reference Figure 1 and Figure 2 As shown, a cleaning mechanism 1000 of an embodiment of the present invention can be used to clean the injection needle 700, the metering needle of the metering system, the injection valve, the nozzle and other parts that need to be cleaned. For the convenience of explanation, the cleaning of the injection needle 700 is taken as an example for description. The cleaning mechanism 1000 of the embodiment of the present invention includes a frame 100, a clamping device 200, a guide wheel group 400 and a wiping device 500. The upper end surface 110 of the frame 100 is provided with a through hole 111. The through hole 111 is in the shape of a long strip, but it can also be in other shapes. The clamping device 200 is connected to the frame 100, referring to Figure 3 As shown, the clamping device 200 includes a driving member 210, a first clamping jaw 220 and a second clamping jaw 230. The driving member 210 is fixedly connected to the frame 100 and is drivingly connected to the first clamping jaw 220 and the second clamping jaw 230. The first clamping jaw 220 and the second clamping jaw 230 pass through the through hole 111 and protrude from the upper end surface 110 of the frame 100. The driving member 210 is used to drive the first clamping jaw 220 and the second clamping jaw 230 to move closer to or away from each other, and a clamping space 240 is formed between the first clamping jaw 220 and the second clamping jaw 230. The guide wheel group 400 includes a first guide wheel 410, which is connected to the upper end surface 110 of the frame 100 and is located at one side of the clamping device 200.

[0025] Reference Figure 1 and Figure 2As shown, the wiping device 500 includes an unwinding wheel 510, a reeling wheel 520 and a cleaning belt 530. The unwinding wheel 510 and the reeling wheel 520 are both connected to the frame 100 and are located on the side of the clamping device 200 away from the first guide wheel 410. The cleaning belt 530 can be a dust-free cloth. The cleaning belt 530 passes through the first guide wheel 410, and the two ends of the cleaning belt 530 are respectively wound around the unwinding wheel 510 and the reeling wheel 520; the cleaning belt 530 includes a first cleaning section 531 and a second cleaning section 532 that are arranged opposite to each other. The first cleaning section 531 and the second cleaning section 532 are both arranged in the clamping space 240 and can approach each other under the drive of the first clamping jaw 220 and the second clamping jaw 230. It should be noted that, since the cleaning belt 530 is constantly moving during the operation of the cleaning mechanism 1000 , the first cleaning section 531 and the second cleaning section 532 do not refer to a fixed section. As long as they are two sections passing through the clamping space 240 , they are understood as the first cleaning section 531 and the second cleaning section 532 .

[0026] With the above solution, since the first cleaning section 531 and the second cleaning section 532 of the cleaning belt 530 are arranged in the clamping space 240 between the first clamping jaw 220 and the second clamping jaw 230, when the glue injection needle 700 that needs to be cleaned moves into the clamping space 240 and is located between the first cleaning section 531 and the second cleaning section 532. Driven by the driving member 210, the first clamping jaw 220 and the second clamping jaw 230 respectively push the first cleaning section 531 and the second cleaning section 532 to move in the direction close to the glue injection needle 700, and make the first cleaning section 531 and the second cleaning section 532 fit the glue injection needle 700. With the rotation of the unwinding wheel 510 and the rewinding wheel 520, the first cleaning section 531 and the second cleaning section 532 are driven to move and can effectively clean the glue injection needle 700, so as to reduce the glue shortage, glue breakage, insufficient glue, no glue and other undesirable conditions caused by the residual glue in the glue injection needle 700. Since the first clamping jaw 220 and the second clamping jaw 230 protrude from the upper end surface 110 of the frame 100, and the first cleaning section 531 and the second cleaning section 532 are arranged in the clamping space 240, the first cleaning section 531 and the second cleaning section 532 are located above the upper end surface 110 of the frame 100 and on both sides of the injection needle 700. When wiping the injection needle 700, the liquid dripping from the injection needle 700 will not drip directly on the first cleaning section 531 and the second cleaning section 532, which can improve the cleaning effect of the first cleaning section 531 and the second cleaning section 532. The solution of using the cleaning belt 530, because the length of the cleaning belt 530 is long, it is not necessary to frequently replace the cleaning belt 530, thereby improving production efficiency.

[0027] Reference Figure 2 and Figure 3As shown, in the embodiment of the present invention, a first soft pad 221 is provided on the side of the first clamping jaw 220 facing the second clamping jaw 230, and the first soft pad 221 is used to abut and cooperate with the first cleaning section 531. A second soft pad 231 is provided on the side of the second clamping jaw 230 facing the first clamping jaw 220, and the second soft pad 231 is used to abut and cooperate with the second cleaning section 532. The first soft pad 221 and the second soft pad 231 can be sponges, silicone parts, rubber parts, etc. The first soft pad 221 and the second soft pad 231 are used to abut and cooperate with the first cleaning section 531 and the second cleaning section 532 respectively, so that the first cleaning section 531 and the second cleaning section 532 can wrap the injection needle 700, thereby improving the cleaning effect of the injection needle 700.

[0028] It is understandable that after the first cleaning section 531 cleans the glue injection needle 700, glue will remain in the first cleaning section 531 toward the second cleaning section 532. When the first cleaning section 531 continues to move around the first guide wheel 410 and is again inserted into the clamping space 240, it will become the second cleaning section 532. At this time, the side with residual glue will still cooperate with the glue injection needle 700, resulting in a worse cleaning effect.

[0029] To solve the above problems, refer to Figure 1 As shown, in the embodiment of the present invention, the cleaning mechanism 1000 includes a flip member 600, one end of which is connected to the frame 100, and the other end of the flip member 600 is provided with a guide groove 621, which runs through one end of the flip member 600, so as to facilitate the installation of the cleaning belt 530. The cleaning belt 530 includes a flip section 533, and the two ends of the flip section 533 are respectively connected to the first cleaning section 531 and the second cleaning section 532, and the flip section 533 is flipped and penetrated in the guide groove 621. It can be understood that by setting the flip member 600 to flip 180°, the side of the cleaning section that is not stained with glue cooperates with the glue injection needle 700, thereby avoiding the glue stuck on the second cleaning section 532 from contaminating the glue injection needle 700 again, which can effectively improve the cleaning effect of the glue injection needle 700.

[0030] Continue to refer to Figure 1 As shown, in an embodiment of the present invention, the flip member 600 includes a connecting section 610 and an inclined section 620 connected to each other, and the connection method can be one-piece molding, or connected by welding, fasteners, etc. The connecting section 610 is fixedly connected to the frame 100, and the fixed connection method can be connected by fasteners such as screws, bolts, and pins. The inclined section 620 is arranged to be inclined upward and is located on the upper end surface 110 of the frame 100. The inclined section 620 is provided with a guide groove 621. By providing the inclined section 620, the flipping reverse direction of the flip section 533 can be adapted, so that the direction of the flip section 533 can be more effectively guided, and the smoothness and stability of the cleaning belt 530 when moving are improved.

[0031] Continue to refer to Figure 1 As shown, in the embodiment of the present invention, two flipping members 600 are provided and are arranged at intervals along the extension direction of the flipping section 533. The tilting angle of the tilting section 620 can be 45°, so after the two flipping members 600 are provided, the flipping section 533 can be flipped 90°, and finally the flipping member 600 continues to flip 90° and cooperates with the fourth guide wheel 450 of the guide wheel assembly 400. It can be understood that by providing two flipping members 600, the direction of the flipping section 533 can be further guided, and while assisting the flipping of the flipping section 533, the smoothness of the movement of the flipping section 533 is improved, and the cleaning belt 530 is prevented from getting stuck during the movement, thereby improving the stability and reliability of the cleaning mechanism 1000.

[0032] Since the residual glue of the glue injection needle 700 may drip onto the cleaning mechanism 1000, in order to prevent the dripping glue from flowing around and causing other parts of the cleaning mechanism 1000 to be contaminated, refer to Figure 4 and Figure 5 As shown, in the embodiment of the present invention, the cleaning mechanism 1000 includes a collecting device 300, which is cylindrical and connected to the frame 100. The collecting device 300 is provided with a receiving chamber 310 for collecting liquid, and the opening of the receiving chamber 310 is located below the through hole 111. Therefore, when the residual glue of the injection needle 700 drips, it enters the receiving chamber 310 through the through hole 111, thereby effectively avoiding glue splashing, improving the cleaning effect, and ensuring the safety and reliability of other components of the cleaning mechanism 1000.

[0033] Reference Figure 6 and Figure 7 As shown, in an embodiment of the present invention, the frame 100 includes a mounting seat 120, the mounting seat 120 is located below the upper end surface 110 of the frame 100, the mounting seat 120 is provided with a mounting groove 121, and the collecting device 300 is detachably connected to the mounting groove 121. The mounting groove 121 is a U-shaped groove, and the collecting device 300 can be installed on the mounting seat 120 through the opening on the side of the mounting groove 121, which is convenient for disassembly and assembly. It can be understood that the collecting device 300 is designed to be detachably connected, and the collected glue can be dumped in time after reaching a certain amount to avoid glue overflow. At the same time, the mounting groove 121 is designed as a U-shaped groove, which can facilitate the disassembly of the collecting device 300 and improve the disassembly efficiency.

[0034] Reference Figure 7As shown, in the embodiment of the present invention, the upper end surface 110 of the mounting seat 120 is provided with a positioning groove 122, and the positioning groove 122 extends to the mounting groove 121 and is arranged around the opening at the upper end of the mounting groove 121. The upper end of the collecting device 300 is provided with a flange 320, and the collecting device 300 is inserted into the mounting groove 121, and the flange 320 and the positioning groove 122 are positioned and matched. Therefore, the relative position of the collecting device 300 and the mounting seat 120 can be quickly determined, which is conducive to aligning the opening of the collecting device 300 with the through hole 111, and avoiding the situation that the collecting device 300 is tilted or misaligned.

[0035] Since the cleaning belt 530 needs to clean the injection needle 700 by continuously moving, it is necessary to record the moving distance of the cleaning belt 530 so as to control the start and stop of the unwinding wheel 510 and the reeling wheel 520. Figure 6 As shown, in the embodiment of the present invention, the guide wheel assembly 400 includes a second guide wheel 420 connected to the frame 100, the side wall of the second guide wheel 420 is surrounded by an anti-skid portion 421, the cleaning belt 530 is wound around the anti-skid portion 421 and can drive the second guide wheel 420 to rotate, and the cleaning mechanism 1000 includes a distance detection device 422, and the distance detection device 422 is connected to the second guide wheel 420. Therefore, when the second guide wheel 420 rotates, the distance detection device 422 can detect how much the second guide wheel 420 rotates, thereby effectively judging the moving distance of the cleaning belt 530.

[0036] Reference Figure 3 As shown, in an embodiment of the present invention, the guide wheel group 400 includes a third guide wheel 430 and a fourth guide wheel 450, and the third guide wheel 430 and the fourth guide wheel 450 are both connected to the upper end surface 110 of the frame 100. Among them, the cleaning belt 530 passes through the third guide wheel 430, the second guide wheel 420, the fourth guide wheel 450 and the first guide wheel 410 in sequence. The guide wheel plays a guiding role, so that the cleaning belt 530 can be unwound and rewound smoothly. It should be noted that the number of guide wheels is selected according to actual conditions, and this embodiment will not be repeated here.

[0037] A dispensing machine according to an embodiment of the present invention comprises the cleaning mechanism 1000 of the above embodiment. The dispensing machine according to the embodiment of the present invention adopts the cleaning mechanism 1000 of the above embodiment, and is connected to the frame 100 by setting a clamping device 200, and the first clamping jaw 220 and the second clamping jaw 230 of the clamping device 200 can move under the drive of the driving member 210. Since the first cleaning section 531 and the second cleaning section 532 of the cleaning belt 530 are arranged in the clamping space 240 between the first clamping jaw 220 and the second clamping jaw 230, when the needle 700 to be cleaned moves into the clamping space 240 and is located between the first cleaning section 531 and the second cleaning section 532. Under the drive of the driving member 210, the first clamping jaw 220 and the second clamping jaw 230 respectively push the first cleaning section 531 and the second cleaning section 532 to move in the direction close to the needle 700, and make the first cleaning section 531 and the second cleaning section 532 fit the needle 700. With the rotation of the unwinding wheel 510 and the rewinding wheel 520, the first cleaning section 531 and the second cleaning section 532 are driven to move and can effectively clean the needle 700, so as to reduce the undesirable conditions such as lack of glue, broken glue, insufficient glue, and no glue caused by residual glue on the needle 700. Since the first clamping jaw 220 and the second clamping jaw 230 protrude from the upper end surface 110 of the frame 100, and the first cleaning section 531 and the second cleaning section 532 are arranged in the clamping space 240, the first cleaning section 531 and the second cleaning section 532 are located above the upper end surface 110 of the frame 100 and on both sides of the needle 700. When wiping the needle 700, the liquid dripping from the needle 700 will not directly drip onto the first cleaning section 531 and the second cleaning section 532, which can improve the cleaning effect of the first cleaning section 531 and the second cleaning section 532. The solution of using the cleaning tape 530 does not require frequent replacement of the cleaning tape 530 due to its long length, thereby improving production efficiency.

[0038] Since the glue dispensing machine adopts all the technical solutions of the cleaning mechanism 1000 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
