Detailed Implementation

[0023] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0024] Example 1: A replacement mechanism for a glue valve nozzle, wherein the nozzle 100 is threadedly connected to the lower end of a glue valve 200, comprising: a base plate 1 and a sleeve 2 rotatably mounted on the upper surface of the base plate 1; the upper end of a rotating shaft 3 is connected to the sleeve 2; the rotating shaft 3, which is driven by a driving mechanism 4, is used to drive the sleeve 2 to rotate; at least one set of mutually cooperating protrusions 51 and grooves 52 are provided between the inner wall of the sleeve 2 into which the nozzle 100 is inserted and the outer surface of the nozzle 100; a sensing plate 61 that rotates with the rotating shaft 3 is fitted on the rotating shaft 3; a counting sensor 62 is provided on the outer side of the sensing plate 61; the counting sensor 62, which cooperates with the sensing plate 61, is used to obtain the number of rotations of the sleeve 2 with the rotating shaft 3.

[0025] Several grooves 52 extending vertically are circumferentially spaced on the outer surface of the lower end of the nozzle 100, and several protrusions 51 that cooperate with the grooves 52 are circumferentially spaced on the inner wall of the upper end of the sleeve 2; the outer surface of the protrusions 51 and the inner wall of the grooves 52 are both arc-shaped.

[0026] A mounting plate 7 is provided below the substrate 1, and the counting sensor 62 is mounted on the mounting plate 7; the rotating shaft 3 and the mounting plate 7, and the sleeve 2 and the substrate 1 are rotatably connected by at least one bearing 8.

[0027] The aforementioned drive mechanism 4 is a motor mounted on the lower surface of the mounting plate 7, and the lower end of the rotating shaft 3 is connected to the output shaft of the motor.

[0028] Example 2: A replacement mechanism for a glue valve nozzle, wherein the nozzle 100 is threadedly connected to the lower end of a glue valve 200, comprising: a base plate 1 and a sleeve 2 rotatably mounted on the upper surface of the base plate 1; the upper end of a rotating shaft 3 is connected to the sleeve 2; the rotating shaft 3, which is driven by a driving mechanism 4, is used to drive the sleeve 2 to rotate; at least one set of mutually cooperating protrusions 51 and grooves 52 are provided between the inner wall of the sleeve 2 into which the nozzle 100 is inserted and the outer surface of the nozzle 100; a sensing plate 61 that rotates with the rotating shaft 3 is mounted on the rotating shaft 3; a counting sensor 62 is provided on the outer side of the sensing plate 61; the counting sensor 62, which cooperates with the sensing plate 61, is used to obtain the number of rotations of the sleeve 2 with the rotating shaft 3.

[0029] A mounting plate 7 is provided below the aforementioned substrate 1, and the counting sensor 62 is mounted on the mounting plate 7; the aforementioned driving mechanism 4 further includes: a motor 41 mounted on the lower surface of the mounting plate 7, a drive pulley 42 connected to the output shaft of the motor 41 and located above the mounting plate 7, and a synchronous pulley 44 that is connected to the drive pulley 42 via a synchronous belt 43, and the synchronous pulley 44 is mounted on the rotating shaft 3.

[0030] When it is necessary to install the nozzle onto the glue valve: First, insert the nozzle to be installed into the sleeve, so that the protrusions and grooves on the nozzle and the sleeve interlock; then, move the glue valve without the nozzle installed to directly above the nozzle installed in the sleeve by manual or automated three-axis drive mechanism; then, drive the glue valve to gradually move down so that the area where the lower end of the glue valve is threadedly connected to the nozzle is gradually embedded into the nozzle. At the same time, drive the rotating shaft to rotate forward by the drive mechanism, thereby automatically installing the nozzle onto the glue valve through the rotational engagement between the threads;

[0031] When it is necessary to detach the nozzle from the glue valve: First, the glue valve with the nozzle installed is moved above the sleeve by a manual or automated three-axis drive mechanism; then, the glue valve is driven to move downward so that the nozzle on the glue valve is embedded in the sleeve, and the protrusions and grooves on the nozzle and sleeve are interlocked; then, the drive mechanism drives the rotating shaft to rotate in the opposite direction, while at the same time, the glue valve is driven to move upward so that the area where the lower end of the glue valve is threadedly connected to the nozzle gradually decreases until the lower end of the glue valve is completely separated from the nozzle remaining in the sleeve, thereby automatically detaching the nozzle from the glue valve;

[0032] The above disassembly and assembly processes can be used in combination. For example, the old nozzle that has been used for a period of time can be removed from the glue valve first, and then the new nozzle can be installed on the glue valve to achieve automated replacement.

[0033] Most importantly, during the above-mentioned nozzle disassembly and assembly process, the threshold for sleeve rotation is first set according to the number of thread turns between the nozzle and the glue valve. Then, the number of rotations of the sleeve with the rotating shaft is obtained in real time by the counting sensor. When the number of rotations of the sleeve with the rotating shaft reaches the set threshold, it indicates that the installation or disassembly of the nozzle is complete. This allows for precise control of the start and stop of sleeve rotation, improving the accuracy of nozzle installation and the efficiency of nozzle disassembly.

[0034] When using the above-mentioned glue valve nozzle replacement mechanism, the nozzle can be disassembled and installed by rotating the sleeve in both the forward and reverse directions. Furthermore, the start and stop of the sleeve rotation can be precisely controlled based on the obtained number of rotations, thereby improving the accuracy of nozzle installation and the efficiency of nozzle disassembly.

[0035] The counting sensor involved in the technical solution was obtained through external purchase and falls within the scope of existing technology, so it will not be described in detail here.

[0036] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
