Description

Technical Field

[0001] This utility model belongs to the field of dispensing machine technology, specifically relating to a dispensing machine frame. Background Technology

[0002] A dispensing machine is a widely used piece of equipment in the electronics manufacturing industry, primarily used to precisely apply adhesives, conductive adhesives, or other bonding agents to specific areas of electronic components or circuit boards. In the electronics manufacturing process, circuit boards of different sizes need to be transported to the dispensing area for precise adhesive application. To meet the dispensing requirements of circuit boards of varying sizes, dispensing machines typically need to be equipped with adjustable conveying devices to ensure the accuracy and stability of the dispensing process.

[0003] Most existing dispensing machine frames use simple fixing methods or a single adjustment mechanism to transport circuit boards. However, in practical use, traditional dispensing machine frames have the following problems:

[0004] 1. Insufficient adaptability of the conveying device: The existing frame is inconvenient to adjust circuit boards of different widths. The adjustment process requires stopping the machine, which reduces production efficiency. At the same time, the adjustment accuracy is low, which can easily lead to the circuit board being conveyed off-center.

[0005] 2. Poor conveying stability: Due to the lack of an effective support mechanism, the circuit board is prone to shaking or shifting during the conveying process, which affects the accuracy of the dispensing operation and may even lead to finished product quality problems.

[0006] 3. Inconvenient operation: The current adjustment mechanism is complex in design, and the manual adjustment process is time-consuming and laborious, which not only increases the workload of operators, but also limits the degree of automation of the equipment. Utility Model Content

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a frame for a dispensing machine that can meet the conveying needs of circuit boards of different specifications, while also possessing stability and ease of operation.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A dispensing machine frame includes a dispensing table, a three-axis moving frame is provided on the top of the dispensing table, a dispensing head is provided at the movable end of the three-axis moving frame, and a conveyor frame is provided on the upper surface of the dispensing table. The conveyor frame is used to transport the circuit board to be dispensed to the lower part of the three-axis moving frame so that the dispensing head can perform dispensing operation on the circuit board.

[0010] The conveyor frame includes a driving mechanism and a second driving mechanism arranged opposite to each other. The driving mechanism and the second driving mechanism cooperate with each other to convey the circuit board to be glued to the glue dispensing area located below the three-axis moving frame.

[0011] A width adjustment mechanism is provided on one side of the second drive mechanism. The width adjustment mechanism is used to adjust the distance between the drive mechanism and the second drive mechanism so that the drive mechanism and the second drive mechanism can transport circuit boards of different widths.

[0012] Furthermore, the drive mechanism includes a side plate, and driven pulleys are provided on both sides of the side plate;

[0013] Furthermore, a motor is connected to one side of the side plate, and a drive wheel is provided at the output end of the motor;

[0014] A first belt is provided on the side of the side plate, and the first belt is connected to the driven pulley and the drive wheel;

[0015] The second drive mechanism has the same structure as the drive mechanism.

[0016] Furthermore, a support strip is fixedly connected to the side of the side plate. The support strip is located inside the first belt and is attached to the first belt.

[0017] Furthermore, the drive mechanism is symmetrically provided with fixing feet on its side bottom, and the fixing feet are connected to the top of the dispensing table.

[0018] The bottom of the second drive mechanism is symmetrically equipped with movable feet;

[0019] The movable foot includes a guide rail connected to the top of the dispensing table, a slide table slidably connected to the guide rail, and the slide table connected to the second drive mechanism.

[0020] Furthermore, the width adjustment mechanism includes a support plate connected to the top of the dispensing table, the number of support plates is set to two, and the support plates are symmetrically distributed on one side of the second drive mechanism.

[0021] A threaded rod is rotatably connected to the support plate, and a linkage seat is sleeved on the threaded rod. The linkage seat and the threaded rod are threadedly engaged.

[0022] One end of the threaded rod is rotatably connected to the side plate, and the linkage seat passes through the second drive mechanism;

[0023] When the threaded rod rotates clockwise, the second drive mechanism moves in the direction of the drive mechanism;

[0024] When the threaded rod rotates counterclockwise, the second drive mechanism moves away from the drive mechanism.

[0025] Furthermore, a linkage pulley is fitted onto one end of the threaded rod, and a second belt is fitted onto the two linkage pulleys;

[0026] A tensioning pulley is connected to the second belt.

[0027] Furthermore, one end of the threaded rod is fixedly connected to a drive disc, the outer side of the drive disc is provided with anti-slip texture, and a handle is rotatably connected to the side of the drive disc.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] The dispensing machine frame provided in this application, by setting up a drive mechanism and a second drive mechanism, and using a width adjustment mechanism to adjust the distance between the two, can accommodate circuit boards of different widths. The drive mechanism and the second drive mechanism have the same structure. Through the cooperation of the first belt, the driven pulley and the drive wheel, the circuit board is smoothly transported under the drive of the motor. At the same time, the support bar provides support for the first belt, avoiding the circuit board shaking and offset problems that occur during the transport process in existing frames, and significantly improving the transport stability.

[0031] The width adjustment mechanism achieves precise movement of the second drive mechanism through the cooperation of the threaded rod and the linkage seat. The linkage pulley and the second belt ensure synchronous rotation of the two threaded rods, thus guaranteeing consistent width changes on both sides during adjustment. Width adjustment becomes simpler and more convenient through the operation of the drive disc and handle. Simultaneously, the locking knob design locks the position of the threaded rods, preventing width errors caused by vibration. This design solves the problems of complex and low-precision width adjustment in existing technologies, improving the adjustment efficiency and adaptability of the dispensing machine frame.

[0032] The movable feet, through the cooperation of the slide table and guide rail, enable the second drive mechanism to move flexibly; the combined design of the fixed and movable feet ensures the stability of the drive mechanism and the second drive mechanism during use. The sliding design of the movable feet solves the problem of the fixed feet' inflexible adjustment in the prior art, further improving the functionality and ease of use of the device.

[0033] The overall structure, through the cooperation of the three-axis moving frame and the dispensing head, enables precise dispensing of circuit boards. The rationally designed frame of the dispensing machine ensures smooth and stable circuit board transport from conveying to dispensing, significantly improving dispensing accuracy and production efficiency. It effectively solves problems such as unstable conveying, complex adjustment, and insufficient adaptability in existing technologies, and has broad application value. Attached Figure Description

[0052] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0053] See Figure 1-6A dispensing machine frame includes a dispensing table 1, a three-axis moving frame 11 on the top of the dispensing table 1, a dispensing head 12 at the movable end of the three-axis moving frame 11, and a conveyor frame 2 on the upper surface of the dispensing table 1. The conveyor frame 2 is used to convey the circuit board to be dispensed to the area below the three-axis moving frame 11 so that the dispensing head 12 can perform dispensing operations on the circuit board. The conveyor frame 2 includes a driving mechanism 21 and a second driving mechanism 22 arranged opposite to each other. The driving mechanism 21 and the second driving mechanism 22 cooperate with each other to convey the circuit board to be dispensed to the dispensing area located below the three-axis moving frame 11. A width adjustment mechanism 25 is provided on one side of the second driving mechanism 22. The width adjustment mechanism 25 is used to adjust the distance between the driving mechanism 21 and the second driving mechanism 22 so that the driving mechanism 21 and the second driving mechanism 22 can adapt to circuit boards of different widths.

[0054] See Figure 1-3 The drive mechanism 21 includes a side plate 211, with driven pulleys 212 on both sides of the side plate 211; a motor 214 is connected to the outer side of one end of the side plate 211, and a drive wheel 215 is provided at the output end of the motor 214; a first belt 213 is provided on the side of the side plate 211, and the first belt 213 is connected to the driven pulleys 212 and the drive wheel 215; the first belt 213 can drive the circuit board to be conveyed along the side plate 211 under the drive of the motor 214; a support bar 2111 is fixedly connected to the side of the side plate 211, the support bar 2111 is located inside the first belt 213, and the support bar 2111 is attached to the first belt 213, thereby providing support for the first belt 213 and preventing vibration during the conveying of the circuit board; the second drive mechanism 22 has the same structure as the drive mechanism 21.

[0055] See Figure 2-4 The drive mechanism 21 has symmetrical fixed feet 23 on its side bottom. The fixed feet 23 are bolted to the top of the dispensing table 1 to ensure that the drive mechanism 21 can be stably installed. The second drive mechanism 22 has symmetrical movable feet 24 on its bottom. The movable feet 24 include a guide rail 241 connected to the top of the dispensing table 1. A slide table 242 is slidably connected to the guide rail 241. The slide table 242 is bolted to the second drive mechanism 22. The slide table 242 can move along the guide rail 241 to realize the displacement adjustment of the second drive mechanism 22.

[0056] See Figure 5-6The width adjustment mechanism 25 includes a support plate 251 connected to the top of the dispensing table 1. Two support plates 251 are symmetrically distributed on one side of the second drive mechanism 22. A threaded rod 252 is rotatably connected to the support plate 251 via a bearing. A linkage seat 253 is fitted onto the threaded rod 252, and the linkage seat 253 and the threaded rod 252 are threaded together. The other end of the linkage seat 253 passes through the side plate of the second drive mechanism 22, allowing the rotation of the threaded rod 252 to move the second drive mechanism 22. One end of the threaded rod 252 is connected to the side plate 211 of the drive mechanism 21 via a bearing, and the other end is fixedly connected to a drive disc 254. Anti-slip textures 2541 are provided on the outer side of the drive disc 254 so that the operator can rotate the drive disc 254 via a handle 2542. When the threaded rod 252 rotates clockwise, the second drive mechanism 22 moves towards the drive mechanism 21; when the threaded rod 252 rotates counterclockwise, the second drive mechanism 22 moves away from the drive mechanism 21.

[0057] See Figure 5-6 One end of the threaded rod 252 is fitted with a linkage pulley 2521, and the two linkage pulleys 2521 are connected by a second belt 256. A tensioning wheel 255 is provided on the second belt 256, which can adjust the tension of the second belt 256 to ensure the synchronous rotation of the two linkage pulleys 2521, thereby realizing the synchronous rotation of the two threaded rods 252.

[0058] See Figure 5-6 A locking knob 2511 is provided on one side of the support plate 251. The locking knob 2511 is used to lock the position of the threaded rod 252. When the locking knob 2511 is turned clockwise, the locking knob 2511 compresses the threaded rod 252 through its internal thread structure, fixing the threaded rod 252 to the support plate 251. When the locking knob 2511 is turned counterclockwise, the locking knob 2511 releases the compression on the threaded rod 252, allowing the threaded rod 252 to rotate freely. By locking and unlocking the locking knob 2511, the position of the threaded rod 252 can be prevented from shifting due to vibration after the width adjustment is completed, further improving the stability and accuracy of the width adjustment.

[0059] The working principle of this utility model is as follows:

[0060] In use, the distance between the drive mechanism 21 and the second drive mechanism 22 is adjusted according to the width of the circuit board to be glued.

[0061] When adjusting the distance between the drive mechanism 21 and the second drive mechanism 22, hold the handle 2542 by hand and turn it clockwise. As the handle 2542 rotates, it will drive the drive disc 254 to rotate synchronously, and the drive disc 254 will drive the threaded rod 252 to rotate synchronously.

[0062] At the same time, with the cooperation of the linkage pulley 2521 and the second belt 256, the two threaded rods 252 will rotate synchronously;

[0063] When the threaded rod 252 rotates, with the cooperation of the linkage seat 253 installed on the second drive mechanism 22, the second drive mechanism 22 will move synchronously, thereby enabling the adjustment of the distance between the drive mechanism 21 and the second drive mechanism 22, so that circuit boards of different widths can be transported.

[0064] The circuit board is placed on the first belt 213 which is positioned opposite to it. Driven by the motor 214 and with the cooperation of the drive wheel 215 and the driven pulley 212, the first belt 213 can move the circuit board.

[0065] The support strip 2111 provided on the side of the side plate 211 can support the first belt 213, thereby making the circuit board conveying process more stable.

[0066] When the circuit board is transported to the foot pad area under the three-axis moving frame 11, the dispensing head 12 located at the movable end of the three-axis moving frame 11 can be used to dispense glue onto the circuit board. After the dispensing is completed, the first belt 213 will transport the circuit board to the next processing area.

[0067] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
