Description

Technical Field

[0001] This utility model belongs to the technical field of circuit board processing equipment, specifically relating to a circuit board dispensing machine that is easy to position. Background Technology

[0002] In the manufacturing process of electronic products, circuit boards are widely used as basic components in various electronic devices. The dispensing process is a crucial step in circuit board production, its purpose being to precisely apply adhesive to designated locations to secure components or provide protection. Traditional dispensing equipment suffers from problems such as complex clamping device operation, insufficient positioning accuracy, and low efficiency in replacing circuit boards.

[0003] Currently, most circuit board dispensing machines on the market adapt to circuit boards of different sizes by adjusting the spacing of the clamping plates. However, most of these devices lack an effective synchronous adjustment mechanism, requiring multiple repetitive operations for adjustment. Furthermore, due to poorly designed positioning devices, the circuit board may shift during dispensing, affecting dispensing accuracy and quality.

[0004] Furthermore, replacing circuit boards often requires manually disassembling multiple components or adjusting the clamping devices one by one, a cumbersome and time-consuming process. This inefficient operation not only reduces production efficiency but also increases the workload of operators. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a circuit board dispensing machine that is easy to position. It can quickly adjust the clamping spacing, achieve automatic positioning of the circuit board, and ensure dispensing accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A circuit board dispensing machine with convenient positioning includes a machine body, and a board positioning mechanism is provided on the top of the machine body. The board positioning mechanism is used to fix the circuit board to be dispensed.

[0008] The plate positioning mechanism includes symmetrically arranged guide shafts, which are connected to the top of the machine body. Two opposing clamping plates are slidably connected on the guide shafts, and the circuit board to be fixed is clamped between the two clamping plates.

[0009] Both clamping plates are provided with a stop and a spring on their outer sides. The spring is located between the stop and the clamping plate, and both the stop and the spring are sleeved on the guide shaft.

[0010] The bottom of the two clamping plates is connected to a linkage mechanism, which enables the two clamping plates to move synchronously.

[0011] Furthermore, clamping grooves are provided on the opposite surfaces of the two clamping plates, so that when the circuit board is fixed, the edge of the circuit board is located in the clamping groove;

[0012] The bottom of the clamping plate is symmetrically provided with sliding seats, which are sleeved on the guide shaft.

[0013] Furthermore, the stop component includes a base plate and a top plate;

[0014] The upper end face of the base plate is symmetrically provided with a first limiting groove;

[0015] The lower end face of the top plate is symmetrically provided with a second limiting groove;

[0016] The guide shaft is located between the first limiting groove and the second limiting groove;

[0017] A locking knob is provided on the upper end face of the top plate, which is used to adjust the distance between the bottom plate and the top plate;

[0018] When the locking knob is turned clockwise, the gap decreases;

[0019] When the locking knob is turned counterclockwise, the gap increases.

[0020] Furthermore, the linkage mechanism includes a positioning seat connected to the top of the machine body, a linkage rod rotatably connected to the top of the positioning seat, a drive rod rotatably connected to both ends of the linkage rod, a pin connecting post rotatably connected to one end of the drive rod, and the top of the pin connecting post connected to the bottom of the clamping plate.

[0021] Furthermore, each end of the guide shaft is provided with a support base, which is connected to the top of the machine body.

[0022] Furthermore, a three-axis movable frame is provided on the top of the machine body, and the movable end of the three-axis movable frame is connected to a rubber head.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This invention solves the problem of inaccurate circuit board positioning in existing technologies by setting up a board positioning mechanism. The board positioning mechanism includes a guide shaft and a clamping plate slidably connected to the guide shaft. The clamping plate has clamping grooves on its opposite surfaces for embedding the edges of the circuit board. With this structural design, when the circuit board is fixed, its centerline coincides with the center line of the guide shaft, thus ensuring the accuracy of the dispensing operation and avoiding dispensing offset problems caused by inaccurate positioning.

[0025] This invention overcomes the shortcomings of existing clamping devices, such as complex adjustment and low efficiency, by designing a combination of a stop component and a spring. The stop component limits the guide shaft through a combination of a base plate and a top plate, and the distance between the base plate and the top plate is adjusted by a locking knob, thereby enabling quick fixing and adjustment of the clamping plate. The spring ensures the stability of the clamping plate during dispensing and provides a certain degree of elastic adjustment, greatly improving the ease of operation and work efficiency of the clamping device.

[0026] This invention solves the problem of synchronous movement of clamping plates in existing technologies through the design of a linkage mechanism. The linkage mechanism consists of a positioning seat, a linkage rod, a drive rod, and a pin connection post. When one clamping plate moves, the rotation of the linkage rod drives the other clamping plate to move synchronously, thereby achieving symmetrical adjustment of the clamping plates. This linkage design not only improves the efficiency of circuit board fixing but also ensures that the circuit board is always in an accurate centered position.

[0027] This invention meets the high-precision requirements of circuit board dispensing by using a three-axis moving frame and dispensing head mounted on the top of the machine body. The three-axis moving frame can be adjusted along the X, Y, and Z directions, allowing the dispensing head to accurately reach each dispensing position on the circuit board. At the same time, the flexibility of the three-axis moving frame increases the applicability of the equipment, enabling it to adapt to the dispensing needs of circuit boards of different sizes and shapes, thus solving the problem of narrow applicability in existing technologies.

[0043] 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.

[0044] See Figure 1-7 A circuit board dispensing machine with convenient positioning includes a machine body 1, and a board positioning mechanism 2 is installed on the top of the machine body 1. The board positioning mechanism 2 is used to position and fix the circuit board to be dispensed, thereby ensuring dispensing accuracy.

[0045] The plate positioning mechanism 2 includes symmetrically arranged guide shafts 21. The two ends of the guide shafts 21 are fixedly connected to the top of the machine body 1 through support seats 211. The support seats 211 can provide stable support for the guide shafts 21, thereby ensuring that the guide shafts 21 will not be displaced or bent when bearing load.

[0046] Two opposing clamping plates 22 are slidably connected to the guide shaft 21, forming an adjustable clamping space between the two clamping plates 22 for clamping circuit boards of different sizes.

[0047] The circuit board to be fixed is placed in the clamping grooves 221 of the two clamping plates 22 by its edge. The clamping grooves 221 can effectively prevent the circuit board from shifting position during the dispensing process.

[0048] See Figure 2-5 The two clamping plates 22 are provided with clamping grooves 221 on their opposite sides. The clamping grooves 221 can ensure that the edge of the circuit board is firmly embedded, thereby improving the fixing effect of the circuit board.

[0049] The bottom of the clamping plate 22 is symmetrically provided with sliding seats 222. The sliding seats 222 are slidably connected with the guide shaft 21 to enable the clamping plate 22 to move freely to accommodate circuit boards of different sizes.

[0050] A stop 23 and a spring 25 are installed on the outer side of the clamping plate 22. The spring 25 is located between the stop 23 and the clamping plate 22 and is used to provide an elastic force to fix the clamping plate 22.

[0051] The design of the stop component 23 allows it to slide smoothly while also providing clamping force through the spring 25, thus maintaining stability when the clamping plate 22 moves.

[0052] See Figure 2 and Figure 6 The stop component 23 is composed of a base plate 231 and a top plate 232;

[0053] The upper end face of the base plate 231 is symmetrically provided with a first limiting groove 2311, and the lower end face of the top plate 232 is symmetrically provided with a second limiting groove 2321.

[0054] The guide shaft 21 passes through the first limiting groove 2311 and the second limiting groove 2321. The bottom plate 231 and the top plate 232 clamp the guide shaft 21 through the cooperation of the limiting grooves.

[0055] A locking knob 233 is provided on the upper end face of the top plate 232. The locking knob 233 is used to adjust the distance between the bottom plate 231 and the top plate 232.

[0056] When the locking knob 233 is turned clockwise, the gap between the base plate 231 and the top plate 232 gradually decreases, the guide shaft 21 is fixed, thereby locking the position of the stop piece 23.

[0057] When the locking knob 233 is turned counterclockwise, the distance between the base plate 231 and the top plate 232 increases, the sliding space of the guide shaft 21 increases, and thus the stop part 23 can move freely on the guide shaft 21.

[0058] See Figure 7 The linkage mechanism 24 is fixed to the top of the body 1 by the positioning seat 241, which is used to support and position the linkage mechanism 24.

[0059] The top of the linkage mechanism 24 is rotatably connected to a linkage rod 242, and the two ends of the linkage rod 242 are respectively rotatably connected to drive rods 243. One end of the drive rod 243 is connected to the bottom of the clamping plate 22 through a pin 244.

[0060] When one clamping plate 22 moves, the pin 244 pulls the drive rod 243, causing the linkage rod 242 to rotate around the central axis of the positioning seat 241, thereby driving the other clamping plate 22 to move synchronously.

[0061] This linkage design ensures that the movement of the two clamping plates 22 remains symmetrical, thereby guaranteeing that the clamping space between the clamping plates 22 is always located on the midline of the guide shaft 21.

[0062] See Figure 4 The two ends of the guide shaft 21 are fixed to the top of the body 1 by the support base 211. The stable structure of the support base 211 ensures that the guide shaft 21 will not deform when bearing the weight of the clamping plate 22 and the circuit board.

[0063] The support base 211 also facilitates the disassembly and installation of the guide shaft 21, thereby making equipment maintenance easier.

[0064] See Figure 1 The top of the body 1 is equipped with a three-axis moving frame 11, which can move along the X, Y and Z directions;

[0065] The movable end of the three-axis moving frame 11 is connected to a dispensing head 12, which is used to precisely dispense adhesive to a designated location on the circuit board.

[0066] The multi-axis movement function of the three-axis moving frame 11 enables dispensing operations with complex paths, thereby meeting the processing needs of different products.

[0067] The working principle of this utility model is as follows:

[0068] According to the width of the plate to be fixed, the spacing between the clamping plates 22 needs to be adjusted first. When adjusting, first place the circuit board to be glued between the two clamping plates 22, and make the edge of the circuit board on the clamping groove 221. Then turn the locking knob 233 clockwise to increase the spacing between the bottom plate 231 and the top plate 232. This allows the stop part 23 to slide smoothly on the guide shaft 21. Slide the stop part 23 towards the clamping plate 22 and compress the spring 25 located between the clamping plate 22 and the stop part 23. When the spring 25 is compressed, turn the locking knob 233 clockwise to bring the bottom plate 231 and the top plate 232 closer to each other and fix the guide shaft 21 between the bottom plate 231 and the top plate 232.

[0069] Under the elastic force of spring 25, the circuit board will be fixed between the two clamping plates 22 during the dispensing process;

[0070] When a new circuit board needs to be replaced, simply pull one of the clamping plates 22 towards the support base 211 by hand;

[0071] Under the action of the linkage mechanism 24 set at the bottom of the clamping plate 22, the two clamping plates 22 will move simultaneously, making it easier to fix and replace the circuit board.

[0072] When one of the clamping plates 22 moves, it pulls the drive rod 243 through the pin 244 at its bottom, and the drive rod 243 pulls the linkage rod 242 to rotate around the central axis of the positioning seat 241, thus driving the other clamping plate 22 to move synchronously.

[0073] Since the positioning seat 241 is located on the center line of the guide shaft 21, when circuit boards of different sizes are fixed by the clamping plate 22, the center line of the circuit board will coincide with the center line of the guide shaft 21.

[0074] 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.
