Description

Technical Field

[0001] The utility model relates to the technical field of factory production equipment, in particular to a glue dispensing machine. Background Art

[0002] During the production of the speaker cavity component, it is necessary to install electronic components on the speaker cavity component, and then apply sealant on the periphery of the speaker cavity component to form a closed space when the speaker cavity is subsequently assembled to protect the electronic components. In addition, it is also necessary to apply fixing glue between the electronic components and the component.

[0003] In practice, the glue dispensing machine has a base and a support frame, and the glue dispensing gun is arranged on the support frame. The glue dispensing gun can move in the Y direction and the Z direction. A support mechanism that can move in the X direction is arranged on the base. The speaker cavity component is placed on the support mechanism for glue dispensing. Glue dispensing requires positioning of the speaker cavity component, so a positioning plate is also required. A first positioning groove is provided on the support mechanism, and the positioning plate can be positioned in the first positioning groove. A plurality of second positioning grooves are provided on the positioning plate, and each second positioning groove can position a speaker cavity component, and then the electronic components are placed on the corresponding speaker cavity component.

[0004] When the worker is operating, he needs to first place multiple speaker cavity components and electronic components in the second positioning slot of the positioning plate, and then place the positioning plate in the first positioning slot of the support mechanism, and then the support mechanism moves to drive the speaker cavity components and electronic components to be glued. After the glue is dispensed, the worker removes the speaker cavity components one by one, and the glue dispenser stops working at this time, resulting in low production efficiency. If the worker operates two positioning plates, one positioning plate is glued on the support mechanism, and the other positioning plate is operated to replace the speaker cavity components, and then the two positioning plates are interchanged, work efficiency can be improved, but the worker frequently alternates the positions of the two positioning plates, and needs to accurately place the positioning plates in the first positioning slot, which is relatively tiring.

The base 10, the support frame 20 and the dispensing mechanism 30 can all adopt existing technologies.

[0063] The support frame 20 is connected to the base 10. The dispensing mechanism 30 is arranged on the support frame 20, and the dispensing mechanism 30 can move along the Z direction and the Y direction. The dispensing mechanism 30 is used to spray out fixing glue and / or sealant. The dispensing mechanism 30 includes a plurality of dispensing guns, specifically two groups of four dispensing guns, each group of dispensing guns includes a fixing glue dispensing gun and a sealing glue dispensing gun. The two fixing glue dispensing guns can simultaneously apply fixing glue to two workpieces. The two sealing glue dispensing guns can simultaneously apply sealant to two workpieces. The support mechanism 40 is arranged on the base 10, and the support mechanism 40 can move along the X direction.

In view of its high cost, another solution can be adopted. Please refer to the subsequent description for details.

[0065] In this embodiment, the positioning plate 50 on the support mechanism 40 moves along the X direction with the support mechanism 40 to perform glue dispensing. The worker takes and places the workpiece on the positioning plate 50 on the feeding mechanism 60. After the workpiece on the positioning plate 50 of the support mechanism 40 is glued, the feeding mechanism 60 replaces the two positioning plates 50, and then the positioning plate 50 on the support plate continues to follow the movement of the support plate to dispense glue. The worker can remove the glued workpiece on the positioning plate 50 that has just been replaced on the feeding mechanism 60 and place the workpiece to be glued. During the whole process, the glue dispensing machine will not be in a long-term stop state, which improves work efficiency, and the worker only needs to complete the taking and placing of the workpiece on the positioning plate 50, without operating the two positioning plates 50 to replace each other, which reduces labor intensity.

[0066] In one embodiment, the positioning plate 50 includes a base plate 51 and positioning protrusions 52 connected to two ends of the base plate 51 , and a groove for placing a workpiece is provided on the base plate 51 .

[0067] The supporting mechanism 40 includes a base 41 , two mounting arms 42 , two strip-shaped supporting blocks 43 and a clamping mechanism 44 .

[0068] The base 41 is movably disposed on the base 10 along the X direction, and the base 41 can be disposed with reference to the prior art.

[0069] The two mounting arms 42 are both connected to one end of the base 41 , and the mounting arms 42 extend along the X direction. The two mounting arms 42 are at the same level.

[0070] The two strip support blocks 43 both extend along the X direction, and the two strip support blocks 43 are respectively connected to the inner sides of the corresponding mounting arms 42, and the strip support blocks 43 are used to support the corresponding positioning protrusions 52. The clamping mechanism 44 is used to fix the positioning protrusions 52 on the strip support blocks 43. Specifically, the substrate 51 is located between the two mounting arms 42, and the two positioning protrusions 52 are respectively located on the two strip support blocks 43.

[0071] In this embodiment, the loading mechanism 60 places the positioning plate 50 on the two strip-shaped support blocks 43, and the clamping mechanism 44 clamps the positioning protrusions 52, so that the positioning plate 50 can move with the base 41 and then dispense glue.

[0072] In one embodiment, a strip-shaped mounting hole 421 is formed on the inner side of the mounting arm 42. The clamping mechanism 44 includes two symmetrical clamping blocks 441, a retaining ring 443, a retaining block 444, a guide rod 445 and a spring 446.

[0073] Two mutually symmetrical clamping blocks 441 are provided with two or more first holes 442 that penetrate through each other, and each clamping block 441 can be embedded in the strip-shaped mounting hole 421 on the same side. The retaining ring 443 is arranged in a one-to-one correspondence with the first hole 442, and its outer ring is connected to the inner wall of one end of the first hole 442 close to the mounting arm 42. The retaining block 444 is arranged in a one-to-one correspondence in the first hole 442, and the retaining block 444 can be abutted against the retaining ring 443. The guide rod 445 is arranged in a one-to-one correspondence with the first hole 442, one end of the guide rod 445 is connected to the bottom of the strip-shaped mounting hole 421, and the other end of the guide rod 445 passes through the retaining ring 443 and is connected to the corresponding retaining block 444. The spring 446 is arranged in a one-to-one correspondence with the guide rod 445, and the spring 446 is sleeved on the corresponding guide rod 445, one end of the spring 446 is abutted against the bottom of the strip-shaped mounting hole 421, and the other end of the spring 446 is abutted against the clamping block 441. A clamping groove 447 along the Z direction is formed on the opposite sides of the two clamping blocks 441 , and the positioning protrusion 52 can be embedded in the corresponding clamping groove 447 .

[0074] In this embodiment, when the loading mechanism 60 places the positioning plate 50 on the two strip support blocks 43, under the action of the spring 446, the two clamping blocks 441 approach each other, so that the positioning protrusions 52 on the same side are embedded in the clamping grooves 447, and the two clamping blocks 441 clamp the two positioning protrusions 52. At this time, the positioning protrusions 52 are supported by the strip support blocks 43, so that the positioning plate 50 is fixed on the strip support blocks 43 and can move in the X direction following the base 41.

[0075] In one embodiment, the loading mechanism 60 drives the positioning protrusion 52 to move around the corresponding strip support block 43; the clamping groove 447 is opened at the end of the clamping block 441 close to the base 41; the end of the clamping block 441 away from the base 41 is connected to the wedge block 448; the inclined surface of the wedge block 448 is connected to the side of the clamping block 441 facing the positioning plate 50; when the positioning protrusion 52 is against the inclined surface of the corresponding wedge block 448 and pushes the clamping block 441 into the strip mounting hole 421, the positioning protrusion 52 on the other substrate 51 is disengaged from the corresponding clamping groove 447.

[0076] In this embodiment, under the drive of the feeding mechanism 60, the positioning protrusion 52 and the substrate 51 move in a rectangular track within the plane formed by the X-axis and the Z-axis. Figure 2 The two left positioning plates 50 rest against the wedge block 448 to compress the wedge block 448, so that the clamping block 441 retreats into the strip mounting hole 421, and the positioning protrusion 52 on the right side is disengaged from the clamping groove 447. As the left positioning plate 50 moves further to the right, the right positioning plate 50 is pushed by the left positioning plate 50 and moves to the right. Finally, the left positioning plate 50 moves to the right and is fixed by the clamping groove 447.

[0077] In one embodiment, a guide groove 511 penetrating along the X direction is formed at the lower end of the substrate 51 .

[0078] The loading mechanism 60 includes a loading seat 61 , a first electric push rod 62 , a lifting plate 63 , a second electric push rod 64 , a strip guide block 65 , a first push plate 66 and a second push plate 67 .

[0079] The loading seat 61 is slidably arranged on the base 10 along the X direction, and the loading seat 61 can be connected to the base 10 through a guide rail. The first electric push rod 62 is arranged on the base 10, and its output end is connected to the loading seat 61, and is used to drive the loading seat 61 to move along the X direction. The lifting plate 63 is slidably arranged on the loading seat 61 along the Z direction. Specifically, the lower end of the lifting plate 63 is connected to a plurality of guide rods 445 extending along the Z direction, and a guide hole is provided at each guide rod 445 on the loading seat 61, and the guide rod 445 is slidably matched with the guide hole. The second electric push rod 64 is arranged on the loading seat 61, and its output end is connected to the lifting plate 63, and is used to drive the lifting plate 63 to rise and fall. Specifically, the loading seat 61 is provided with an electric push installation hole penetrating along the Z direction, and the second electric push rod 64 is arranged at the lower end of the loading seat 61, and the output end of the second electric push rod 64 passes through the electric push installation hole and is connected to the lifting plate 63. The strip guide block 65 is connected to the upper end surface of the lifting plate 63, and the strip guide block 65 extends along the X direction. The strip guide block 65 is also gap-matched with the guide grooves 511 of the two substrates 51. A plurality of specific strip guide blocks 65 can be provided, and correspondingly, a guide groove 511 needs to be provided on each substrate 51. The upper end of the strip guide block 65 is a pointed end, which facilitates its own cooperation with the guide groove 511. The first push plate 66 is connected to one end of the loading seat 61 away from the first electric push rod 62. The second push plate 67 is connected to the other end of the loading seat 61 close to the first electric push rod 62. When the lifting plate 63 is raised, the first push plate 66 can be against the corresponding substrate 51; when the lifting plate 63 is lowered, the second push plate 67 can be against the corresponding substrate 51.

[0080] In this embodiment, Figure 2 There are two positioning plates 50 in the figure. The left positioning plate 50 will be referred to as the first positioning plate 50 later, and the right positioning plate 50 will be referred to as the second positioning plate 50. The first electric push rod 62 arranged on the right side drives the loading seat 61 to move rightward, and the first push plate 66 abuts against the first positioning plate 50, thereby driving the first positioning plate 50 to move rightward and press against the wedge block 448, so that the positioning protrusion 52 on the second positioning plate 50 is disengaged from the clamping groove 447. As the first electric push rod 62 further drives the loading seat 61 to move rightward, the first positioning plate 50 and the second positioning plate 50 abut against each other, thereby pushing the second positioning plate 50 to move rightward and disengage from the strip support block 43, and the first positioning plate 50 cooperates with the clamping groove 447 after moving, and the clamping groove 447 fixes the first positioning plate 50.

[0081] After the second positioning plate 50 is separated from the strip support plate, the second electric push rod 64 drives the lifting plate 63 to move downward. At this time, the lifting plate 63 is separated from the guide groove 511 of the first positioning plate 50. The two mounting arms 42 can drive the first positioning plate 50 to move in the X direction to complete the dispensing of the workpiece. Until the upper end of the second positioning plate 50 is lower than the lower end of the first positioning plate 50, the first electric push rod 62 drives the loading seat 61 to move to the left. At this time, the second push plate 67 on the right side abuts against the right end of the second positioning plate 50 below. As the loading seat 61 moves further to the left, the second positioning plate 50 passes under the first positioning plate 50, and then when the positioning protrusion 52 of the second positioning plate 50 moves to the bottom of the left end of the strip support block 43, the lifting plate 63 rises, and the positioning protrusion 52 on the second positioning plate 50 moves to the top of the left end of the strip support block 43. At this time, the strip guide block 65 on the lifting plate 63 is re-matched with the guide groove 511 of the first protrusion. Then the first electric push rod 62 drives the loading seat 61 to move to the left, and the above process can be repeated, thereby completing the replacement of the first positioning plate 50 and the second positioning plate 50. The worker only needs to be on one side of the first push plate 66 and install the workpiece on the nearest positioning plate 50, which is more labor-saving.
