Description

Technical Field

[0001] This utility model belongs to the field of dispensing machines, specifically a dispensing machine that facilitates loading and unloading. Background Technology

[0002] As a precision fluid control device in industrial production, the dispensing machine uses air pressure to force out fluids such as adhesives and silicone, and, in conjunction with a high-precision motion control mechanism, accurately dispenses the adhesive onto the target location along a preset path. In the electronics manufacturing industry, the dispensing process for printed circuit boards is an indispensable step. During dispensing, the circuit board is placed on a clamping base to ensure stability during the process. After dispensing, the circuit board is removed from the clamping base.

[0003] Currently, there are two methods for loading and unloading circuit boards: manual loading and unloading, and automated loading and unloading using automated equipment. Manual loading and unloading requires workers to manually adjust the clamping components on the clamping base to secure the circuit board, and then adjust the clamping components again to release the circuit board after dispensing adhesive, which is cumbersome and significantly reduces the efficiency of loading and unloading circuit boards. Automated loading and unloading using automated equipment involves complex equipment structures, higher initial costs, and higher maintenance costs during subsequent repairs. Therefore, both methods have certain drawbacks.

[0004] To address these issues, those skilled in the art have proposed a dispensing machine that facilitates loading and unloading of materials. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a dispensing machine that facilitates loading and unloading.

[0006] A dispensing machine for easy loading and unloading includes a machine base and a frame mounted on the machine base. The frame is equipped with a dispensing mechanism for dispensing adhesive onto circuit boards. A placement platform is located on the upper part of the machine base. A moving component is located on the upper part of the placement platform. A clamping seat with a hollow internal structure is located on the upper part of the moving component. A clamping component for clamping the circuit board is located on the clamping seat. An unlocking component that works in conjunction with the clamping component is located on the upper part of the placement platform in front of the moving component.

[0007] Preferably, the dispensing mechanism includes a guide rail first disposed on the upper front side of the frame, an electric slider first slidably disposed on the guide rail first, a rectangular frame disposed on the front side of the electric slider first, a mounting plate slidably disposed inside the rectangular frame, and a dispensing head disposed on the mounting plate.

[0008] Preferably, a threaded rod is rotatably provided on the inner side of the rectangular frame, and the threaded rod is threadedly connected to the mounting plate. Two guide rods are symmetrically distributed on the left and right sides inside the rectangular frame. The mounting plate is slidably connected to the guide rods. A motor is provided at the top of the rectangular frame, and the output shaft of the motor is connected to the top end of the threaded rod.

[0009] Preferably, the moving component includes a second guide rail disposed on the upper part of the placement platform, a second electric slider slidably disposed on the second guide rail, and the upper part of the second electric slider being connected to the bottom of the clamping seat.

[0010] Preferably, the clamping assembly includes a crossbar fixedly installed inside the clamping seat, with springs sleeved at both ends of the outer side of the crossbar. Two symmetrically distributed moving blocks are slidably arranged on the crossbar. The two ends of the springs are respectively connected to the moving blocks and the inner wall of the clamping seat. A clamping plate is provided on the upper part of the moving blocks. Rubber pads are provided on the side of the two clamping plates that are close to each other. The circuit board is located on the upper part of the clamping seat and between the two rubber pads.

[0011] Preferably, the upper part of the clamping seat has two sliding openings for the moving block to move, and the upper part of the moving block is located in the sliding opening and slidably connected to the sliding opening.

[0012] Preferably, a connecting block is fixedly provided on the front side of the movable block, and the front sides of the two connecting blocks that are close to each other are both sloped.

[0013] Preferably, the unlocking component includes a limiting plate disposed on the front side of the upper part of the placement platform, and two compression wedges symmetrically distributed on the rear side of the limiting plate, with the side of the compression wedges away from the limiting plate penetrating into the interior of the clamping seat.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention utilizes a combination of a moving component, a clamping component, and an unlocking component. An electric slider drives the clamping seat to contact the limiting plate, automatically adjusting the position of the clamping plates. Operators simply place the circuit board on the clamping seat; when the clamping seat moves away from the limiting plate, the two clamping plates move closer together to automatically clamp and fix the circuit board. After dispensing, when the clamping seat moves closer to the limiting plate, the two clamping plates move away from each other to automatically release the circuit board. This eliminates the need for cumbersome manual adjustments or complex automated structures, significantly simplifying the operation process and effectively improving the efficiency of circuit board loading and unloading.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] As attached Figure 1 To be continued Figure 7 As shown:

[0027] This utility model provides a dispensing machine that facilitates loading and unloading, including a machine base 1 and a frame 2 mounted on the machine base 1. The frame 2 is equipped with a dispensing mechanism 3 for dispensing adhesive onto circuit boards. A placement platform 4 is mounted on the upper part of the machine base 1. A moving component 5 is mounted on the upper part of the placement platform 4. A clamping seat 6 with a hollow internal structure is mounted on the upper part of the moving component 5. A clamping component 7 for clamping the circuit board is mounted on the clamping seat 6. An unlocking component 8 for cooperating with the clamping component 7 is mounted on the upper part of the placement platform 4 in front of the moving component 5.

[0028] When applying adhesive to the circuit board, it is placed on the clamping seat 6. The clamping component 7 can then hold the circuit board in place to ensure its stability during the adhesive application process.

[0029] refer to Figure 1 and Figure 2 The moving component 5 includes a guide rail 51 disposed on the upper part of the placement platform 4, and an electric slider 52 slidably disposed on the guide rail 51. The upper part of the electric slider 52 is connected to the bottom of the clamping seat 6.

[0030] Among them, the electric slider 52 can drive the clamping seat 6 to move back and forth, thereby facilitating the movement of the circuit board on the clamping seat 6, and thus facilitating the dispensing process on the circuit board.

[0031] refer to Figure 1 , Figure 4 and Figure 5 The clamping assembly 7 includes a crossbar 71 fixedly installed inside the clamping seat 6. Springs 72 are sleeved on both ends of the outer side of the crossbar 71. Two moving blocks 73 are slidably arranged on the crossbar 71. The two ends of the springs 72 are connected to the moving blocks 73 and the inner wall of the clamping seat 6, respectively. A clamping plate 74 is provided on the upper part of the moving block 73. Rubber pads 75 are provided on the side of the two clamping plates 74 that are close to each other. The circuit board is located on the upper part of the clamping seat 6 and between the two rubber pads 75.

[0032] refer to Figure 4 and Figure 6 The upper part of the clamping seat 6 has two sliding openings for the moving block 73 to move. The upper part of the moving block 73 is located inside the sliding opening and is slidably connected to the sliding opening.

[0033] refer to Figure 5 and Figure 7 A connecting block 76 is fixedly installed on the front side of the movable block 73, and the front sides of the two connecting blocks 76 that are close to each other are both sloped.

[0034] refer to Figure 1 , Figure 5 and Figure 7 The unlocking component 8 includes a limiting plate 81 set on the upper front side of the placement platform 4. Two compression wedges 82 are symmetrically distributed on the rear side of the limiting plate 81. The side of the compression wedges away from the limiting plate 81 penetrates into the interior of the clamping seat 6.

[0035] During the dispensing of adhesive onto the circuit board, the electric slider 52 drives the clamping seat 6 forward until it contacts the limiting plate 81. The movement of the clamping seat 6 causes the connecting block 76 to move synchronously. During the movement of the connecting block 76, it will contact the extrusion wedge plate 82. As the connecting block 76 continues to move, under the extrusion wedge plate 82, it will cause the moving block 73 to slide on the crossbar 71, thereby extruding the spring 72 and causing the clamping plate 74 to move. At this time, the two clamping plates 74 move away from each other. Then, the operator can place the circuit board on the clamping seat 6 and between the two clamping plates 74. After the circuit board is placed, the electric slider 52 drives the clamping seat 6 to move backward. The movement of the clamping seat 6 causes the connecting block to move away from the extrusion wedge plate 82, thereby gradually eliminating the extrusion pressure on the connecting block 76. At this time, the elastic force of the spring 72 can drive the two clamping plates 74 to move closer to each other, thereby clamping the circuit board and completing the loading of the circuit board.

[0036] After the dispensing mechanism 3 finishes dispensing the circuit board, the clamping seat 6 is moved forward again to move the two clamping plates 74 away from each other, so that the circuit board can be removed from the clamping seat 6. This completes the unloading of the dispensed circuit board. The entire unloading process does not require manual fixing of the circuit board, making the unloading of the circuit board more convenient and ensuring the efficiency of dispensing the circuit board.

[0037] refer to Figure 1 and Figure 2 The dispensing mechanism 3 includes a guide rail 31 located at the upper front end of the frame 2, an electric slider 32 slidably mounted on the guide rail 31, a rectangular frame 33 located at the front of the electric slider 32, a mounting plate 34 slidably mounted inside the rectangular frame 33, and a dispensing head 35 mounted on the mounting plate 34.

[0038] refer to Figure 3 A threaded rod 36 is rotatably provided on the inner side of the rectangular frame 33. The threaded rod 36 is threadedly connected to the mounting plate 34. Two guide rods 37 are symmetrically distributed on the left and right sides inside the rectangular frame 33. The mounting plate 34 is slidably connected to the guide rods 37. A motor 38 is provided on the upper part of the rectangular frame 33. The output shaft of the motor 38 is connected to the top of the threaded rod 36.

[0039] Among them, the operation of the electric slider 32 can drive the rectangular frame 33 to move left and right, thereby driving the dispensing head 35 to move left and right. Then, the operation of the motor 38 can drive the threaded rod 36 to rotate. The rotation of the threaded rod 36, with the cooperation of the guide rod 37, can drive the mounting plate 34 to move up and down, so that the dispensing head 35 can move up and down. Thus, by moving the dispensing head 35 in multiple directions, it is convenient to perform more comprehensive dispensing work on the circuit board.

[0040] Working principle: When dispensing glue onto the circuit board, the electric slider 52 first moves the clamping seat 6 forward to contact the limiting plate 81. At this time, the extrusion wedge 82 extrudes the connecting block 76. After being extruded, the connecting block 76 moves, which in turn moves the clamping plate 74. At this time, the two clamping plates 74 move away from each other, allowing the circuit board to be placed on the clamping seat 6 and between the two clamping plates 74. Then, the electric slider 52 moves the clamping seat 6 backward and separates from the limiting plate 81. At this time, the extrusion pressure on the connecting block 76 gradually disappears. Then, the elastic force of the spring 72 can move the two clamping plates 74 closer together, thereby clamping the circuit board and completing the loading of the circuit board. Then, the glue dispensing mechanism 3 can dispense glue onto the circuit board. After the glue dispensing is completed, the clamping seat 6 is moved forward again, which moves the two clamping plates 74 away from each other, allowing the circuit board to be removed from the clamping seat 6, completing the unloading of the glued circuit board. The entire loading and unloading process does not require manual fixing of the circuit board.
