Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a circuit board processing dispensing machine. Background Technology

[0002] Circuit boards enable the miniaturization and visualization of circuits, playing an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. In order to fix numerous components onto the circuit board, glue needs to be applied to the fixed positions on the circuit board, commonly known as dispensing.

[0003] In the prior art, when using a dispensing machine, in order to prevent the circuit board from shaking on the dispensing machine's worktable, the circuit board is usually fixed by a clamp. However, the clamp is usually fixed by electrical equipment such as a cylinder, but these electrical devices are inconvenient to control, which makes the circuit board easy to be damaged by clamping. Utility Model Content

[0004] This utility model proposes a circuit board dispensing machine to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a circuit board processing dispensing machine, comprising a worktable, a bracket slidably connected to the upper surface of the worktable, a dispensing head fixedly connected to one side of the bracket, two mutually symmetrical cylinders fixedly connected to the upper surface of the worktable, a clamping plate fixedly connected to the output end of the cylinders, a limiting device provided on one side of the clamping plate, the limiting device comprising two pads, the two pads being fixedly connected to one side of the two clamping plates respectively, a threaded cylinder fixedly connected to one side of one of the pads, a threaded rod being threadedly connected inside the threaded cylinder, and a circular plate fixedly connected to one end of the threaded rod.

[0006] The effect achieved by the above components is as follows: When dispensing glue onto circuit boards of different sizes, the operator first places the circuit board between two clamping plates. The operator then rotates the circular plate, causing the threaded rod to rotate within the threaded cylinder. The total length of the threaded rod and cylinder changes. Once the total length is adjusted to a suitable level, the operator stops rotating the circular plate and activates the cylinder. The cylinder causes the two clamping plates to move closer together, with the circular plate on one clamping plate pressing against the pad of the other clamping plate. This limits the maximum displacement of the two clamping plates, allowing them to press against the circuit board and secure it. Finally, glue is dispensed onto the circuit board through the dispensing head on the bracket. The limiting device further restricts the maximum displacement of the two clamping plates, preventing damage to the circuit board caused by the cylinder's movement.

[0007] Preferably, a groove is provided on one side of the circular plate, and a handle is fixedly connected to the circular plate by means of the groove.

[0008] The effect achieved by the above-mentioned components is to increase the contact area between the worker's hand and the circular plate by means of the handle in the groove, thereby making it easier for the worker to rotate the circular plate and bringing convenience to the worker.

[0009] Preferably, the circular plate has an annular groove on its arc surface, and a fixed ring is rotatably connected to the circular plate via the annular groove. A scale is fixedly connected to one side of the fixed ring, and a square tube is fixedly connected to one side of the pad. The internal dimensions of the square tube are adapted to the dimensions of the scale.

[0010] The effect achieved by the above components is as follows: when the circular plate rotates with the threaded rod, the fixed ring on the circular plate rotates with the circular plate, and the scale slides in the square tube. The staff can easily judge the total length of the threaded rod and the threaded cylinder by observing the scale.

[0011] Preferably, a rubber pad is fixedly connected to one side of another of the pads, the size of which is adapted to the size of the circular plate.

[0012] The effect achieved by the above-mentioned components is that the rubber pads protect the circular plate and prevent damage from collisions between the pads and the circular plate.

[0013] Preferably, the bracket is provided with an auxiliary device at the dispensing head. The auxiliary device includes two symmetrical mounting frames, which are fixedly connected to the bracket. The two mounting frames are located on both sides of the dispensing head. A fixing plate is slidably installed inside the mounting frame. One end of the two fixing plates is fixedly connected to the same protective cover. A plug rod is slidably installed on one side of the mounting frame. The fixing plate has a plug hole corresponding to the plug rod. The size of the plug rod is adapted to the size of the plug hole.

[0014] The effect achieved by the above components is as follows: when the dispensing head is not needed, the operator moves the protective cover, and the two fixing plates on one side of the protective cover are inserted into the interior of the mounting frame. Then, the operator moves the insertion rod, which passes through the mounting frame and inserts into the insertion hole of the fixing plate, thus fixing the fixing plate. The protective cover set by the auxiliary device covers the dispensing head, thus protecting the dispensing head and preventing glue from dripping onto the worktable, thereby improving the practicality of the dispensing machine.

[0015] Preferably, one end of the insertion rod is fixedly connected to a pull rope, and one end of the pull rope is fixedly connected to the mounting frame.

[0016] The effect achieved by the above components is that by setting up a pull rope, the maximum displacement of the insertion rod is limited, preventing the insertion rod from falling when not in use.

[0017] Preferably, the arc surface of the protective cover is fixedly connected to a handle, and the surface of the handle is provided with anti-slip texture.

[0018] The aforementioned components achieve the following effect: by incorporating handles, they facilitate the movement of the protective cover by staff, thus providing convenience for them.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] When applying adhesive to circuit boards of different sizes, the operator first places the circuit board between two clamping plates. The operator then rotates the circular plate, causing the threaded rod to rotate within the threaded cylinder. The total length of the threaded rod and cylinder changes as the total length is adjusted. Once the total length is appropriate, the operator stops rotating the circular plate and activates the cylinder. The cylinder moves the two clamping plates closer together, with the circular plate on one clamping plate pressing against the pad on the other, thus limiting the maximum displacement of the two clamping plates. At this point, the two clamping plates press against the circuit board, securing it in place. Finally, adhesive is applied to the circuit board through the dispensing head on the support. The limiting device further restricts the maximum displacement of the two clamping plates, preventing damage to the circuit board caused by the cylinder's movement. Attached Figure Description

[0026] Reference Figure 1-4As shown, this embodiment discloses a circuit board processing dispensing machine, including a worktable 1. A bracket 2 is slidably connected to the upper surface of the worktable 1. A dispensing head 3 is fixedly connected to one side of the bracket 2. Two symmetrical cylinders 4 are fixedly connected to the upper surface of the worktable 1. A clamping plate 5 is fixedly connected to the output end of the cylinder 4. A limiting device 6 is provided on one side of the clamping plate 5. An auxiliary device 7 is provided on the bracket 2 corresponding to the dispensing head 3.

[0027] Reference Figure 1-4 As shown, the limiting device 6 includes two pads 61, which are fixedly connected to one side of the two clamping plates 5 respectively. A threaded cylinder 62 is fixedly connected to one side of one of the pads 61. A threaded rod 63 is threadedly connected inside the threaded cylinder 62. A circular plate 64 is fixedly connected to one end of the threaded rod 63. When applying adhesive to circuit boards of different sizes, the operator first places the circuit board between two clamping plates 5. Then, the operator rotates a circular plate 64, which, along with a threaded rod 63, rotates within a threaded cylinder 62. The total length of the threaded rod 63 and the threaded cylinder 62 changes. Once the total length is adjusted to a suitable level, the operator stops rotating the circular plate 64 and opens the cylinder 4. The cylinder 4 moves the two clamping plates 5 closer together, with the circular plate 64 on one clamping plate abutting against the pad 61 of the other clamping plate. This limits the maximum displacement of the two clamping plates 5. The two clamping plates then press against the circuit board, securing it in place. Finally, adhesive is applied to the circuit board through the dispensing head 3 on the bracket 2. The limiting device 6 further limits the maximum displacement of the two clamping plates 5, preventing damage to the circuit board caused by the clamping plates 5 under the influence of the cylinder 4.

[0028] Reference Figure 1-4 As shown, a groove is provided on one side of the circular plate 64, and a handle 68 is fixedly connected to the circular plate 64 via the groove. The handle 68 in the groove increases the contact area between the worker's hand and the circular plate 64, thus facilitating the worker's rotation of the circular plate 64 and providing convenience. An annular groove is provided on the arc surface of the circular plate 64, and a fixing ring 65 is rotatably connected to the circular plate 64 via the annular groove. A scale 66 is fixedly connected to one side of the fixing ring 65, and a square tube 67 is fixedly connected to one side of the pad 61. The internal dimensions of the square tube 67 are adapted to the dimensions of the scale 66. When the circular plate 64 rotates with the threaded rod 63, the fixing ring 65 on the circular plate 64 rotates with the circular plate 64, and the scale 66 slides in the square tube 67. The worker can easily determine the total length of the threaded rod 63 and the threaded cylinder 62 by observing the scale 66. A rubber pad 69 is fixedly connected to one side of the other pad 61, and the dimensions of the rubber pad 69 are adapted to the dimensions of the circular plate 64. By setting the rubber pad 69, the circular plate 64 is protected, preventing the pad 61 from colliding with the circular plate 64 and causing damage.

[0029] Reference Figure 1-4 As shown, the auxiliary device 7 includes two symmetrical mounting frames 71, which are fixedly connected to the bracket 2. The two mounting frames 71 are located on either side of the dispensing head 3. A fixing plate 72 is slidably inserted inside each mounting frame 71. One end of each fixing plate 72 is fixedly connected to the same protective cover 73. A rod 74 is slidably inserted into one side of each mounting frame 71. The fixing plate 72 has a corresponding insertion hole 75 at the insertion rod 74, and the size of the rod 74 matches the size of the insertion hole 75. When the dispensing head 3 is not in use, the operator moves the protective cover 73, and the two fixing plates 72 on one side of the protective cover 73 are inserted into the interior of the mounting frame 71. Then, the operator moves the rod 74, which passes through the mounting frame 71 and inserts into the insertion hole 75 of the fixing plate 72, thus fixing the fixing plate 72. The protective cover 73 of the auxiliary device 7 covers the dispensing head 3, protecting it and preventing glue from dripping onto the worktable 1, thereby improving the practicality of the dispensing machine.

[0030] Reference Figure 1-4 As shown, a pull rope 77 is fixedly connected to one end of the insertion rod 74, and the other end of the pull rope 77 is fixedly connected to the mounting frame 71. The pull rope 77 limits the maximum displacement of the insertion rod 74, preventing it from falling when not in use. A handle 76 is fixedly connected to the arc surface of the protective cover 73, and the surface of the handle 76 has anti-slip texture. The handle 76 facilitates the movement of the protective cover 73 by the operator, providing convenience.

[0031] Working principle: When dispensing adhesive onto circuit boards of different sizes, the operator first places the circuit board between two clamping plates 5. Then, the operator pulls handle 68 to rotate the circular plate 64. The circular plate 64, along with the threaded rod 63, rotates within the threaded cylinder 62, changing the total length of the threaded rod 63 and the threaded cylinder 62. At this time, the fixing ring 65 on the circular plate 64 rotates relative to the circular plate 64, and the scale 66 slides within the square tube 67. The operator can easily determine the total length of the threaded rod 63 and the threaded cylinder 62 by observing the scale 66. When the total length of the threaded rod 63 and the threaded cylinder 62 is adjusted to... After reaching the appropriate length, the operator stops rotating the handle 68 and opens the cylinder 4. The cylinder 4 brings the two clamping plates 5 closer together, with the circular plate 64 on one clamping plate 5 pressing against the pad 61 on the other clamping plate 5, thus limiting the maximum displacement of the two clamping plates 5. At this point, the two clamping plates 5 are pressing against the circuit board, thus fixing the circuit board. Finally, glue is applied to the circuit board through the dispensing head 3 on the bracket 2. The limiting device 6 further limits the maximum displacement of the two clamping plates 5, preventing the clamping plates 5 from damaging the circuit board under the action of the cylinder 4.

[0032] When the dispensing head 3 is not needed, the operator moves the protective cover 73 by the handle 76. The two fixing plates 72 on one side of the protective cover 73 are inserted into the interior of the mounting frame 71. Then, the operator moves the insertion rod 74, which passes through the mounting frame 71 and inserts into the insertion hole 75 of the fixing plate 72, thus fixing the fixing plate 72. The protective cover 73 set by the auxiliary device 7 covers the dispensing head 3, thus protecting the dispensing head 3 and preventing glue from dripping onto the worktable 1, thereby improving the practicality of the dispensing machine.
