Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0026] To solve the above problems, Figure 1 As shown, the embodiment of the utility model provides a replaceable needle dispensing machine, including a driving device 1, a dispensing device 2 and a clamping device 3; the clamping device 3 includes a moving part and a clamping part, and the fixed end of the clamping part is fixedly connected to the top of the moving part, such as Figure 2 As shown, the clamping component includes a power unit, a clamping linkage plate 31, a clamping support seat 32, a clamping positioning plate 33 and a clamping slide 34. The clamping positioning plate 33 is arranged in the clamping support seat 32, and multiple clamping slides 34 are arranged in the clamping positioning plate 33 and are slidably connected to the clamping positioning plate 33. The two clamping linkage plates 31 are respectively arranged on both sides of the clamping positioning plate 33 and are slidably connected to one end of the multiple clamping slides 34. The connecting ends of the two clamping linkage plates 31 are respectively rotatably connected to one end of the power unit.

[0027] It should be noted that the driving device 1 is used to drive the dispensing device 2 to rise or fall, so as to facilitate the dispensing of parts that need to be glued. The clamping device 3 is used to clamp the dispensing needle on the dispensing device 2 and rotate to unscrew the dispensing needle. The dispensing needle is then taken out by the manipulator and the required dispensing needle is inserted. The manipulator here plays the role of transferring the dispensing needle. The dispensing needle is then screwed onto the glue tube by the clamping device 3, thereby achieving the effect of replacing the dispensing needle. The power unit is used to drive the two clamping linkage plates 31 to rotate. When the two clamping linkage plates 31 rotate in relative directions, the first slide plate and the second slide plate are driven to slide relative to each other. The clamping positioning plate 33 is used to support the sliding of the first slide plate and the second slide plate, thereby achieving the effect of clamping the needle. When the dispensing needle needs to be loosened, the power unit drives the two clamping linkage plates 31 to rotate in opposite directions, thereby driving the first slide plate and the second slide plate to slide in opposite directions, thereby achieving the effect of loosening the dispensing needle.

[0028] In one embodiment of the present invention, Figure 3 As shown, the clamping support seat 32 includes a support base 321, a support boss 322, a support limiting column 323 and a support cover plate, a plurality of the support bosses 322 are respectively arranged on the circular side of the support base 321, a plurality of the support limiting columns 323 are spaced apart on the circular side of the support base 321, and the bottom of the support cover plate is respectively connected to the top of the plurality of the support bosses 322.

[0029] It should be noted that in order to position the clamping positioning plate 33, a clamping support seat 32 is provided. The support base 321 in the clamping support seat 32 is used to support the clamping positioning plate 33. The support cover plate is connected to the support boss 322 by bolts so that the support cover plate can press the clamping positioning plate 33 to prevent the clamping positioning plate 33 from being displaced or rotated. A plurality of support limit columns 323 are respectively arranged at intervals on the circular side edges of the support base 321 to limit the sliding distance of the first slide plate and the second slide plate to prevent the first slide plate and the second slide plate from sliding out of the clamping positioning plate 33.

[0030] In one embodiment of the present invention, Figure 4As shown, the clamping positioning plate 33 includes a clamping plate body 331 , a clamping opening 332 and a clamping T-shaped slot 333 , and a plurality of the clamping T-shaped slots 333 are symmetrically opened in the clamping plate body 331 , and the clamping opening 332 is opened at the center of the clamping plate body 331 .

[0031] It should be noted that the clamping opening 332 is used for the lower part of the dispensing needle to pass through, so that the first slide plate and the second slide plate can be clamped to the upper part of the dispensing needle. The upper part of the dispensing needle is made of metal and can withstand a larger clamping force. The number of multiple clamping T-shaped grooves 333 is equal to the number of the first slide plate and the second slide plate. The clamping T-shaped grooves 333 can support and position the sliding of the first slide plate and the second slide plate.

[0032] In one embodiment of the present invention, Figure 5 As shown, the multiple clamping slides 34 include a first slide and a second slide, and the structures of the first slide and the second slide are the same; the first slide includes two slide bodies 341 and two connecting slides 342, each of the slide bodies 341 is arranged in a clamping T-shaped slide groove 333, and is slidably connected to the clamping T-shaped slide groove 333, one end of each connecting slide column 342 is fixedly connected to the side of a slide body 341, and the other end of each connecting slide column 342 is slidably connected to a clamping T-shaped slide groove 333.

[0033] It should be noted that multiple clamping slides 34 are used to clamp or loosen the dispensing needle. In order to adapt to the two clamping positioning plates 33 and to facilitate the connection between the sliding column 342 and the corresponding linkage waist-shaped hole 312, the two slide bodies 341 in the first slide and the two slide bodies 341 in the second slide are respectively arranged in each clamping T-shaped slide groove 333 in a back-to-back direction, thereby achieving the effect that the two clamping positioning plates 33 can smoothly drive the first slide and the second slide to slide.

[0034] In one embodiment of the present invention, Figure 6 As shown, each of the clamping linkage plates 31 includes a linkage plate body 311, a linkage waist-shaped hole 312, a linkage connecting plate 313, a connecting first through hole 314 and a connecting second through hole 315, the connecting first through hole 314 is opened at one end of the linkage connecting plate 313, the other end of the linkage connecting plate 313 is fixedly connected to the outer side surface of the linkage plate body 311, the center of the linkage plate body 311 is opened with the connecting second through hole 315, and a plurality of the linkage waist-shaped holes 312 are opened on the linkage plate body 311 and are located on both sides of the connecting second through hole 315.

[0035] It should be noted that two linkage waist-shaped holes 312 are provided on each linkage plate body 311, and the two linkage waist-shaped holes 312 respectively drive the two connecting slides 342 to shift, and the shift of the two connecting slides 342 can respectively drive the two slide plates 341 to slide, and a first connecting through hole 314 is provided at one end of the linkage connecting plate 313 to facilitate rotational connection with one end of the power connecting buckle, so that the power unit can drive the two clamping linkage plates 31 to rotate, and a second connecting through hole 315 is provided at the center of the linkage plate body 311 to facilitate the lower part of the dispensing needle to pass through, thereby facilitating the clamping of the upper part of the dispensing needle.

[0036] In one embodiment of the utility model, the power unit includes a power motor, a power threaded rod, a power connecting buckle, a power support seat and a power rotating shaft. The top of the power support seat is fixedly connected to the fixed end of the power motor, the working end of the power motor is fixedly connected to one end of the power threaded rod, one end of the two power connecting buckles are respectively mounted on the power threaded rod and rotatably connected to the power threaded rod, and the other ends of the two power connecting buckles are respectively rotatably connected to the two connecting first through holes 314 through the power rotating shaft.

[0037] It should be noted that in order to realize the rotation of the two clamping linkage plates 31, a power motor in the power unit drives the power threaded rod to rotate. When the power threaded rod rotates clockwise, it drives the two power connecting buckles to move toward each other. When the power threaded rod rotates counterclockwise, it drives the two power connecting buckles to move in opposite directions. In this way, the relative or opposite rotation effect of the two clamping linkage plates 31 is achieved; in order to ensure that the two power connecting buckles move toward or away from each other on a power threaded rod, the thread of one power connecting buckle is designed as a positive thread, and the thread of the other power connecting buckle is designed as a negative thread. In this way, when the power threaded rod rotates, the two power connecting buckles will move in the corresponding thread direction to achieve the desired movement effect. The power support seat is used to support the power motor to ensure that the power motor can work stably. The power shaft facilitates the power connecting buckle and the linkage connecting plate 313 to have a firm connection when the angle changes.

[0038] In one embodiment of the utility model, the moving component includes a moving mounting plate, a moving linear slide, a moving support frame and a moving motor. The moving support frame is arranged at the bottom of the moving mounting plate, the fixed end of the moving linear slide is fixedly connected to the side of the moving support frame, the fixed end of the moving motor is arranged on the working end of the moving linear slide, and the working end of the moving motor is fixedly connected to the bottom of the support base 321.

[0039] It should be noted that in order to realize the function of raising or lowering the clamping component, a moving component is set. In the moving component, a moving support frame is set at the bottom of the moving mounting plate, and a moving motor is set on the working end of the moving linear slide. The working end of the moving motor passes through the mounting plate and is fixedly connected to the bottom of the support base 321. In this way, when there is no need to replace the dispensing needle, the moving motor is driven by the moving linear slide to descend to the bottom of the moving mounting plate. When the dispensing needle needs to be replaced, the moving linear slide drives the moving motor to rise, so that the clamping component on the moving motor covers the dispensing needle. Once the clamping component clamps the dispensing needle, the moving motor will drive the clamping component to rotate, thereby achieving the effect of unscrewing the dispensing needle.

[0041] It should be noted that in order to realize the up and down movement of the dispensing device 2, a driving device 1 is set. In the driving device 1, the driving cylinder is vertically arranged on the top of the driving support frame, and the working end of the driving cylinder is fixedly connected to the lower end of the driving linear guide through the driving connecting plate, so that the driving cylinder can drive the driving linear guide to move up and down linearly. The slider on the driving linear guide is fixedly connected to the side of the driving support frame to support the guide rail in the driving linear guide to slide downward.

[0043] It should be noted that in order to achieve glue dispensing, a glue dispensing device 2 is set up. In the glue dispensing device 2, the glue dispensing mounting frame is arranged on the side of the driving linear guide rail, so that when the guide rail in the driving linear guide rail slides up and down, the glue dispensing mounting frame is driven to move up and down. The glue tube is arranged on the glue dispensing mounting frame, so that the glue dispensing mounting frame drives the glue tube to move. The top of the glue tube is connected to the glue supply device through a hose, which is convenient for glue to enter the glue tube and then be sprayed out through the glue dispensing needle. The glue sprayed by the glue dispensing needle is evenly sprayed on the parts that need to be glued. The upper end of the glue dispensing needle is rotatably connected to the bottom of the glue tube, which is convenient for replacing the glue dispensing needle.
