Technical Field

[0001] The utility model relates to the field of glue coating guns, in particular to an anti-clogging glue coating gun. Background Art

[0002] In the process of product assembly, glue dispensing is a common step used to bond or position two or more components. This task is usually completed by automatic dispensing equipment, which is equipped with a dispensing gun that can accurately apply glue to designated parts of the product or apply it along a specific path. After the dispensing is completed, the glue on the head of the dispensing gun tends to dry, which may affect the subsequent dispensing work, so the gun head needs to be cleaned. However, due to surface tension, glue is easily left on the gun head, and the gun head is usually small in size, making cleaning difficult. Therefore, technicians in this field urgently need to develop an anti-clogging glue gun that can quickly and effectively clean the residual glue at the glue outlet. Utility Model Content

[0024] The drawings are only used for illustrative purposes and should not be construed as limitations of this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product.

[0025] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the utility model is further described below in conjunction with the drawings and embodiments.

[0026] As shown in the attached drawings, an anti-clogging glue gun includes a glue gun body 1, a driving member 2, a connecting rod 3, a sliding table 4, a driven wheel 7, and a cleaning clamp 8;

[0027] One end of the connecting rod 3 is connected to the driving member 2, and the other end of the connecting rod 3 is fixedly connected to the sliding platform 4. The sliding platform 4 is rotatably provided with a storage wheel 5, a winding wheel 6 and a driven wheel 7;

[0028] The glue gun body 1 is provided with a latching tooth 9 at a position corresponding to the driven wheel 7, the latching tooth 9 is meshed with the driven wheel 7, and the cleaning clamping claw 8 is fixedly connected to the driven wheel 7 by bolts;

[0029] The storage wheel 5 is provided with a cleaning belt 10, which is released from the storage wheel 5, wrapped around the cleaning clamp 8, and then wound onto the take-up wheel 6; Figure 1 shown.

[0030] In some embodiments, the driving member 2 includes a housing 20, a piston 23 slidably mounted in the housing 20, an electromagnet 21, and an elastic member 22 disposed between the electromagnet 21 and the piston 23, and the piston 23 is fixedly connected to one end of the connecting rod 3, such as Figure 4 As shown, the piston 23 is made of magnetic metal, and one end of the housing 20 is provided with a through hole for accommodating the connecting rod 3.

[0031] In some embodiments, the cleaning clamp 8 is provided with a guide groove 81 and a cleaning surface 82 and a recovery surface 83 which are arranged opposite to each other. The cleaning tape 10 is led out from the storage wheel 5, passes through the guide groove 81, surrounds the cleaning surface 82 and the recovery surface 83, and then is wound onto the take-up wheel 6. By providing the guide groove 81, the cleaning tape 10 is parallel to the cleaning surface 82 when it is at the cleaning surface 82, and is in more full contact with the nozzle 11, thereby achieving a good cleaning effect. At the same time, the arc-shaped recovery surface 83 reduces the stress of the cleaning tape 10 during the process of winding the cleaning tape 10 onto the take-up wheel 6, thereby avoiding the occurrence of the breaking of the cleaning tape 10. Figure 5 shown.

[0032] In some embodiments, a first motor 51 and a second motor 61 are further provided. The housing of the first motor 51 is fixedly connected to the sliding table 4, and the output end of the first motor 51 is connected to the storage wheel 5; the housing of the second motor 61 is fixedly connected to the sliding table 4, and the output end of the second motor 61 is connected to the winding wheel 6. Figure 2 As shown, the release and winding of the cleaning belt 10 are controlled by the first motor 51 and the second motor 61 to improve the wiping efficiency.

[0033] In some embodiments, the sliding table 4 is rotatably provided with a first tensioning wheel 41 and a second tensioning wheel 42 acting on the cleaning belt 10. The first tensioning wheel 41 and the second tensioning wheel 42 can both swing toward or away from the glue gun body 1, so that the cleaning belt 10 remains in a taut state, preventing the loose paper tape from affecting the cleaning effect.

[0034] In some embodiments, the elastic member 22 is a spring.

[0035] In some embodiments, the cleaning tape 10 is made of non-woven fabric, which can fully wipe and absorb residual glue and has a certain strength to avoid breaking during the wiping process.

[0036] In order for the cleaning jaws 8 to fully fit the shape of the glue nozzle 11 of the glue gun body 1 , the cleaning jaws 8 are made of a flexible material, such as silicone or polyurethane.

[0037] Furthermore, in order to make the cleaning more thorough, with the central axis of the glue gun body 1 as the axis of symmetry, two sets of driving parts 2, connecting rods 3, sliding tables 4, a first tensioning wheel 41, a second tensioning wheel 42, a storage wheel 5, a winding wheel 6, a driven wheel 7, cleaning jaws 8 and a cleaning belt 10 are symmetrically arranged on the left and right.

[0038] The working principle of this embodiment is as follows:

[0039] When in cleaning mode, the electromagnet 21 is in a closed state, and the piston 23 moves downward under the action of its own gravity and the elastic force of the elastic member 22, pushing the connecting rod 3 downward, thereby causing the sliding table 4 to move downward, and then the left driven wheel 7 starts to rotate counterclockwise under the action of the latch tooth 9, and the right driven wheel 7 starts to rotate clockwise under the action of the latch tooth 9. Further, the left cleaning jaw 8 and the right cleaning jaw 8 both swing in the direction close to the glue gun body 1, and finally the cleaning jaws 8 on the left and right sides wrap the glue nozzle 11. At this time, the left storage wheel 5 and the left winding wheel 6 both rotate in the clockwise direction, and the left cleaning belt 10 is released from the left storage wheel 5, bypasses the left first tensioning wheel 41 and enters the left guide groove 81, thereby surrounding the left cleaning surface 82 and the left The left side recovery surface 83 is then bypassed from the left recovery surface 83 by the second tensioning wheel 42 on the left side and wound onto the left tape winding wheel 6; the right storage wheel 5 and the right tape winding wheel 6 both rotate in the counterclockwise direction, and the right cleaning tape 10 is released from the right storage wheel 5, bypasses the first tensioning wheel 41 on the right side and enters the right guide groove 81, thereby surrounding the right cleaning surface 82 and the right recovery surface 83, and then bypasses the second tensioning wheel 42 on the right side from the right recovery surface 83 and wound onto the right tape winding wheel 6, so as to wipe and clean the glue nozzle 11 from top to bottom. The surface of the cleaning tape 10 has capillary fibers. Under the action of the capillary effect, the residual glue in the glue nozzle 11 will be absorbed by the cleaning tape 10, and the cleaning tape 10 that has absorbed the glue is rewound onto the tape winding wheel 6 to avoid contacting the glue nozzle 11 again.

[0040] When switching from the cleaning mode to the working mode, the electromagnet 21 is in the on state, and the piston 23 moves upward under the action of the magnetic force and compresses the elastic member 22 until the elastic force of the elastic member 22 is balanced with the magnetic force of the electromagnet 21, and the piston 23 drives the connecting rod 3 to move upward and the sliding table 4 moves upward with the connecting rod 3, and then the left driven wheel 7 starts to rotate clockwise under the action of the latch tooth 9, and the right driven wheel 7 starts to rotate counterclockwise under the action of the latch tooth 9, and further, the left cleaning jaw 8 and the right cleaning jaw 8 both swing away from the glue gun body 1, and finally the left cleaning jaw 8 and the right cleaning jaw 8 are both in a position perpendicular to the side wall of the glue gun body 1, at this time, the storage wheel 5 and the winding wheel 6 on the left and right sides do not rotate. Figure 3 shown.

[0041] When in working mode, the electromagnet 21 remains in an on state, so that the cleaning jaws 8 remain at a position away from the glue gun body 1, and do not affect the normal operation and glue discharge of the glue gun body 1.

[0042] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here.
