Description

Technical Field

[0001] This application relates to the technical field of brush manufacturing, and in particular to an automatic glue-dispensing machine for brush manufacturing. Background Technology

[0002] During the manufacturing process of the brush, the bristles need to be stuffed into the sheet metal first, and then glued together at the joint between the bristles and the sheet metal.

[0003] The current method involves placing the assembled bristles and sheet metal into a tray in sequence, then mounting the tray on a glue-dispensing machine. The glue dispenser on the machine dispenses glue sequentially at each joint between the bristles and sheet metal. After each dispensing cycle, the machine must stop before the tray can be replaced, and then the machine can be restarted. This process results in significant time waste, greatly impacting the overall glue-dispensing efficiency of the brushes and consequently limiting the speed and output of brush production, which needs improvement. Utility Model Content

[0004] The purpose of this application is to provide an automatic glue-dispensing machine for brush production, in order to improve the efficiency of glue dispensing for the entire brush.

[0005] This application provides an automatic glue-dispensing machine for brush production, employing the following technical solution: It includes a glue-dispensing table, a glue dispenser connected to the glue-dispensing table, a glue delivery pipe connected to the glue dispenser, and a drive assembly connected to the glue-dispensing table. The drive assembly drives the glue dispenser to move along the X, Y, and Z axes. A carrier plate is slidably connected to the glue-dispensing table, and at least two trays are mounted on the carrier plate. At least two sets of positioning rods are connected to the carrier plate, each set of positioning rods including at least two positioning rods. Each tray is provided with at least two positioning slots, the number of positioning slots being the same as the number of positioning rods in each set of positioning rods. The positioning rods are used to cooperate with the positioning slots. A sliding assembly is connected to the glue-dispensing table, driving the carrier plate to slide.

[0006] By adopting the above technical solution, when the brushes in one tray are being filled with glue, a tray can be installed on another set of positioning rods. After the brushes in the tray have been filled with glue, the sliding component drives the carrier plate to slide, so that the tray to be filled with glue corresponds to the glue dispenser. The glue dispenser continues to fill the brushes with glue through the driving component. During this process, the tray after the brushes have been filled with glue is replaced, that is, the tray is switched without stopping the glue dispensing machine, which improves the overall glue dispensing efficiency of the brushes and increases the speed and output of brush production.

[0007] Optionally, the end of the positioning rod away from the dispensing table is arc-shaped.

[0008] By adopting the above technical solution, the end of the positioning rod away from the glue dispensing table is set into an arc shape, which makes it easier for the positioning rod to be inserted into the positioning groove, so that the pallet can be installed on the carrier plate more smoothly, thereby improving the efficiency of pallet installation.

[0009] Optionally, two of the positioning rods in each group are connected to the dispensing platform, and the dispensing platform is connected to an adjustment assembly for adjusting the distance between the two positioning rods.

[0010] By adopting the above technical solution, the adjustment component can adjust the distance between the two positioning rods on the dispensing platform, adapt to different sized trays, and enhance the versatility of the automatic dispensing machine.

[0011] Optionally, the adjustment assembly includes a limiting block disposed on the positioning rod and a fixing block threadedly connected to the positioning rod. The carrier plate is provided with a limiting groove and a sliding groove communicating with the limiting groove. The limiting groove is used to slide and engage with the limiting block, and the positioning rod slides and engages with the sliding groove.

[0012] By adopting the above technical solution, when it is necessary to adjust the distance between the two positioning rods, the fixing block is rotated to separate it from the carrier plate. The positioning rod is then moved, and the sliding engagement between the limiting block and the limiting groove guides and limits the sliding of the positioning rod, thereby improving the stability of the positioning rod's movement and preventing it from dislodging from the groove during sliding. This ensures the positioning rod moves precisely to the corresponding position. Once the positioning rod has moved to the appropriate position, the fixing block is rotated to abut against the carrier plate, thus fixing the rod in place.

[0013] Optionally, the limiting block is rotatably connected to the positioning rod.

[0014] By adopting the above technical solution, the limiting block changes from sliding friction to rolling friction during the movement process, reducing friction and improving the efficiency of the moving positioning rod.

[0015] Optionally, the tray is provided with a clearance groove that communicates with the positioning groove, and the clearance groove is used for the fixing block to engage.

[0016] By adopting the above technical solution, when installing the pallet, the fixing block is inserted into the clearance groove, so that the bottom surface of the pallet abuts against the upper surface of the carrier plate, increasing the contact area between the pallet and the carrier plate and improving the stability of the pallet placed on the carrier plate.

[0017] Optionally, the outer surface of the tray is provided with two ear plates facing each other.

[0018] By adopting the above technical solution, the pallet is equipped with ear plates, which facilitates the handling and replacement of the pallet by the operators, reduces waiting time, improves the overall glue dispensing efficiency of the brush, and speeds up the production speed and output of the brush.

[0019] Optionally, the sliding assembly includes a lead screw rotatably connected to the dispensing platform, a first driving member for driving the lead screw to rotate, and two slide rails disposed on the dispensing platform. The first driving member is connected to the dispensing platform, the carrier plate is threadedly connected to the lead screw, and the carrier plate slides in cooperation with the slide rails.

[0020] By adopting the above technical solution, the driving component drives the lead screw to rotate, that is, the carrier plate slides along the extension direction of the slide rail. The sliding cooperation between the carrier plate and the slide rail plays a guiding and limiting role in the sliding of the carrier plate, thereby improving the stability of the sliding of the carrier plate.

[0021] Optionally, in each group of positioning rods, four positioning rods are connected to the carrier plate, and four positioning slots are provided on the tray, with the positioning slots located at the four corners of the tray.

[0022] By adopting the above technical solution, the positioning posts on the carrier plate cooperate with the positioning grooves at the four corners of the pallet, which can improve the stability of the pallet when it is installed on the carrier plate, prevent the pallet from shaking or shifting during the glue pouring process, and ensure accurate glue pouring position.

[0023] Optionally, the driving assembly includes a first movable plate slidably connected to the dispensing platform, a second driving member for driving the first movable plate to slide along the X-axis direction, a second movable plate slidably connected to the first movable plate, a third driving member for driving the second movable plate to slide along the Y-axis direction, a third movable plate slidably connected to the second movable plate, and a fourth driving member for driving the third driving plate to slide along the Z-axis direction. The dispensing device is connected to the third movable plate, the second driving member is connected to the dispensing platform, the third driving member is connected to the first movable plate, and the fourth driving member is connected to the second movable plate.

[0024] By adopting the above technical solution, the glue applicator can move along the X, Y, and Z axes under the action of the second, third, and fourth driving components, and the glue application position can be flexibly adjusted, which facilitates precise glue application to the connection between the brush bristles and the sheet metal at different locations, thus improving the accuracy and efficiency of brush glue application.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When the brushes in one tray are being glued, a tray can be installed on another set of positioning rods. After the brushes in the tray have been glued, the sliding component drives the carrier plate to slide, so that the tray to be glued corresponds to the glue dispenser. The glue dispenser continues to glue the brushes through the drive component. During this process, the tray after the brushes have been glued is replaced, that is, the tray is switched without stopping the glue dispenser, which improves the overall glue dispensing efficiency of the brushes and increases the speed and output of brush production.

[0026] 2. The adjustment component can adjust the distance between the two positioning rods on the dispensing platform to adapt to different sized trays and enhance the versatility of the automatic dispensing machine. Attached Figure Description

[0040] Combination Figure 2 , Figure 3 and Figure 4As shown, the carrier plate 2 is equipped with at least two trays 4. In this embodiment, for example, there are three trays 4. When two of the trays 4 are on the carrier plate 2, the third tray 4 is used to hold brush bristles and sheet metal. The carrier plate 2 is connected to at least two sets of positioning rods 5. In this embodiment, for example, there are two sets of positioning rods 5 connected to the carrier plate 2. Each set of positioning rods 5 includes at least two positioning rods 5. In this embodiment, for example, there are four positioning rods 5. All four positioning rods 5 are fixedly connected to the carrier plate 2. The end of the positioning rod 5 away from the carrier plate 2 is arc-shaped. Each tray 4 has four positioning slots 41. The four positioning slots 41 are located at the four corners of the tray 4.

[0041] The implementation principle of an automatic glue-dispensing machine for brush production according to an embodiment of this application is as follows: The tray 4 with the brushes installed is placed on the carrier plate 2, and the positioning rod 5 is engaged in the positioning groove 41 to improve the stability of the tray 4 on the carrier plate 2. The first driving component 32 drives the lead screw 31 to rotate, so that the tray 4 corresponds to the glue applicator 6. Through the second driving component 82, the third driving component 84, and the fourth driving component 86, the glue applicator 6 moves along the X-axis, Y-axis, and Z-axis, so that the glue applicator 6 applies glue to each connection between the sheet metal and the brush bristles. During the glue application process, another tray 4 is installed on the carrier plate 2, saving the installation time of the tray 4. When the brushes in one of the trays 4 have been glued, the first driving component 32 drives the lead screw 31 to rotate, so that the un-glueed tray 4 corresponds to the glue applicator 6, and the glue applicator 6 continues to work. At this time, the tray 4 that has been glued is replaced, saving time and improving the overall glue application efficiency of the tray 4.

[0042] Example 2 The difference between this embodiment and Embodiment 1 is that, in combination with Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in each group of positioning rods 5, two positioning rods 5 are arranged opposite each other on the carrier plate 2. The glue dispensing table 1 is connected to an adjustment assembly 9, which is used to adjust the distance between the two positioning rods 5. The adjustment assembly 9 includes a limiting block 91 rotatably connected to each positioning rod 5 and a fixing block 92 threadedly connected to each positioning rod 5. The radius of the limiting block 91 is larger than the radius of the positioning rod 5. The carrier plate 2 has a sliding groove 21 and a limiting groove 22 communicating with the sliding groove 21. The positioning rod 5 slides in the sliding groove 21, and the limiting block 91 slides in the limiting groove 22. The extension direction of the sliding groove 21 and the extension direction of the limiting groove 22 are both perpendicular to the moving direction of the carrier plate 2. The tray 4 has a relief groove 43 communicating with the positioning groove 41. The relief groove 43 is used for the fixing block 92 to be inserted. When the tray 4 is installed, the bottom surface of the tray 4 abuts against the upper surface of the carrier plate 2.
