Description

Technical Field

[0001] The invention relates to a glue dispensing machine, in particular to a roll material glue dispensing machine. Background Art

[0002] In modern electronic product processing, terminals are usually standardized as a universal product. Finished terminals are set on very long material strips for easy transportation and assembly. During production, the material strips on the dispensing table need to be glued. Unwinding stations and rewinding stations are set on both sides of the dispensing machine. The unwinding material strips are rewound at the rewinding station after the dispensing machine completes the glue dispensing. During the dispensing process, the material tape needs to be accurately positioned so that the dispensing mechanism can achieve downward dispensing. However, for the material tape, since the material tape changes from the bent state of the unwinding station to the unfolded state during dispensing, the unfolded material tape will bend downward in the middle, that is, the height of the two sides of the unfolded material tape is higher than the height of the middle part. At this time, if the material tape is dispensed, it is impossible to achieve accurate dispensing of the material tape compared to the ideal horizontal material tape. In summary, how to implement glue dispensing on a material strip that is bent downward in the middle has become an urgent problem that researchers in this field need to solve.

DETAILED DESCRIPTION

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0017] like Fig. 9 As shown, when the material strip 001 is placed on the glue dispensing station 2 for glue dispensing after being unwound, the material strip 001 may bend upward or downward in the middle due to bending, and the bent material strip 001 may cause inaccurate glue dispensing position.

[0018] like Figure 1-9As shown, in order to address the situation where the material strip may bend downward during the glue dispensing process on the glue dispensing table 2, the present embodiment discloses a roll material dispensing machine, specifically comprising: a machine base 1, on which two parallel glue dispensing tables 2 are arranged, and the spacing between the two glue dispensing tables 2 is adjusted according to the width of the material strip 001 in a horizontal state, and the spacing between the two glue dispensing tables 2 is adjusted to a suitable state to meet the requirement that both sides of the left and right width of the material strip 001 are supported on the corresponding glue dispensing tables 2, at this time, the lifting support seat 5 located at the gap rises, and the top of the lifting support seat 5 is against the middle of the bottom of the material strip 001, and the lifting support seat 5 pushes the downward bent material strip 001 to form the material strip 001 in a horizontal state, and at this time, the position on the horizontal material strip 001 where glue dispensing is required will not be offset due to the bending of the material strip 001.

[0019] The progressive drive mechanism 4 drives the material belt 001 to perform progressive motion. When the material belt 001 is transported to the bottom of the corresponding glue dispensing mechanism 3, the glue dispensing mechanism 3 moves downward to dispense glue to the terminals on the material belt 001. For example, in the present embodiment, the glue dispensing mechanism 3 is provided in three numbers. When the same terminal on the material belt 001 passes under different glue dispensing mechanisms 3, it stops and the glue dispensing mechanism 3 moves downward to dispense glue. The three glue dispensing mechanisms 3 can dispense glue to different positions of the same terminal in sequence.

[0020] like Figure 2 As shown, in some embodiments, in order to ensure that the material belt always moves along the length direction of the dispensing table 2 when moving on the dispensing table 2, this embodiment adopts a limit groove 21 to be opened along the straight direction of the inner side edge of the top surface of the dispensing table 2, and the side edge of the material belt 001 is placed on the horizontal plane of the limit groove 21.

[0021] A limiting groove 21 is provided on the side of the dispensing table 2 close to the material belt 001. The limiting groove 21 is a step structure. The left and right side edges of the material belt 001 are matched with the vertical surface of the limiting groove 21. The vertical surfaces of the two limiting grooves 21 are matched with the material belt 001 to achieve that the material belt 001 can only move along the length direction of the dispensing table 2. The horizontal surfaces of the two limiting grooves 21 are used to support the bottom surfaces on both sides of the material belt 001.

[0022] like Figure 2As shown, in some embodiments, when the lifting support seat 5 acts on the middle bottom part of the material belt 001, for the material belt that is thinner or easily deformed, the material belt 001 will be corrected from the downward bending to the horizontal state; but for the material belt 001 that is thicker or not easy to deform, when the lifting support seat 5 acts on the middle bottom part of the material belt 001, the material belt 001 is still in a downward bending state and moves upward as a whole, so that the two sides of the material belt 001 will deviate from the horizontal plane of the limiting groove 21. At this time, if glue is dispensed on the material belt 001, the position on the material belt 001 where glue needs to be dispensed is still inaccurate. In order to solve the above technical problems, the present embodiment adopts the following scheme, a liftable pressing plate 6 is arranged above the glue dispensing platform 001, and the bottom of the pressing plate 6 has a limiting protrusion 61 matching the limiting groove 21, and an adjustable spacing material passing gap is formed between the limiting protrusion 61 and the limiting groove 21.

[0023] In this embodiment, cylinders are fixed on the outside of the two dispensing stations 2, and the cylinders control the lifting of the pressure plate 6, thereby controlling the spacing between the limiting protrusion 61 and the limiting groove 21; the matching methods of the limiting protrusion 61 and the limiting groove 21 are as follows: 1. The spacing between the limiting protrusion 61 and the limiting groove 21 can be adjusted to be slightly larger than the thickness of the material strip 001. At this time, the side of the material strip moves in the material gap formed between the limiting protrusion 61 and the limiting groove 21, and the lifting support seat 5 rises, so that the side of the material strip 001 extends in the material gap along its width direction, and the material strip 001 is corrected to a horizontal state. The limiting protrusion 61 and the limiting groove 21 only need to be adjusted once during the whole process; 2. The lifting support seat 5 rises, driving the downward-bent material strip 001 to rise as a whole, and then the pressing plate 6 descends, and the side of the material strip 001 is pressed against the limiting groove 21 through the limiting protrusion 61. At this time, the material strip 001 is corrected to a horizontal state; after the dispensing is completed, the pressing plate 6 rises to facilitate the movement of the terminal on the next material strip 001 to the bottom of the dispensing mechanism 3. This coordination method needs to be linked with the progressive drive mechanism 4 to frequently drive the pressing plate 6 to rise and fall.

[0024] like Figure 4As shown, in some embodiments, in order to illustrate the specific structure of the progressive drive mechanism 4, the progressive drive mechanism 4 used in this embodiment includes: a first slide rail 41, which is fixed to the outer side of one of the dispensing stations 2, and its length direction is parallel to the length direction of the dispensing station 2; a first cylinder 42, on which a slider matched with the first slide rail 41 is fixed; a horizontal plug-in 43, one end of which is connected to the output end of the first cylinder 42, and is located above the dispensing station 2; a vertical plug-in 44, which is connected to the bottom surface of the other end of the horizontal plug-in 43 Then, the first cylinder 42 controls the vertical plug-in 44 to be inserted into the material hole 002 of the material belt 001; the first horizontally rotating synchronous belt 45 is connected to the first cylinder 42, and is suitable for driving the first cylinder 42 to perform progressive motion or reciprocating motion along the first slide rail 41; the outer side of the dispensing table 2 is respectively provided with a driving wheel 46 and a driven wheel 47 in the front and rear directions; the first synchronous belt 45 is tensioned on the driving wheel 46 and the driven wheel 47; the output end of the rotary motor 48 is connected to the driving wheel 46; In this embodiment, the first cylinder 42 is arranged outside one of the dispensing stations 2 through a linear rail assembly (first slide rail, slider), the rotation of the first synchronous belt 45 is realized by the cooperation of the driven wheel 47 and the driving wheel 46, and the cylinder body of the first cylinder 42 is fixed on the first synchronous belt 45, so that the first cylinder 42 can move along the length direction of the dispensing station 2; the output end of the first cylinder 42 is connected to a horizontal plug-in 43, and the end of the horizontal plug-in 43 is fixed to a vertical plug-in 44; When the first cylinder 42 is at the first limit position, the first cylinder 42 is activated to drive the vertical plug 44 to descend and insert into the material hole 002 of the material belt 001 (such as Figure 7 As shown), the first synchronous belt 45 rotates, driving the first cylinder 42 to move along the length of the dispensing station 2 to perform intermittent progressive motion; When the first cylinder 42 moves to the second extreme position, the first cylinder 42 drives the vertical plug-in 44 and the horizontal plug-in 43 to rise, and separates the vertical plug-in 44 from the material hole 002 of the material belt 001. The first synchronous belt 45 reverses, driving the first cylinder 42 to quickly return to the first extreme position along the dispensing table 001.

[0025] like Figure 3 , 5As shown, in some embodiments, it is necessary to adjust the distance between the two dispensing stations 2 to meet the dispensing of material strips 001 with different widths. How to achieve the distance adjustment of the two dispensing stations 001? In this embodiment, at least one group of first fixed seats 71, sliding seats 72, and screw rods 73 are provided on the machine base; a first fixed seat 71 is provided at the bottom of one of the dispensing stations 2, and the first fixed seat 71 is fixedly connected to the machine base 1; a sliding seat 72 is provided at the bottom of the other dispensing station 2, and the bottom of the sliding seat 72 is connected to the machine base 1 through a second slide rail 74, and the length direction of the second slide rail 71 is perpendicular to the length direction of the dispensing station 2; an adjusting motor 75 is fixed on the first fixed seat 71, and a screw rod 73 is provided at its output end, and a nut 75 matching the screw rod 73 is provided on the sliding seat 72; In this embodiment, the dispensing station 2 connected to the first fixed seat 71 is fixed on the machine base 1, and the dispensing station 2 connected to the sliding seat 72 is slidably set on the machine base 1. The adjusting motor 76 is fixed on the first fixed seat 71, and one end of the screw rod 73 is connected to the output end of the adjusting motor 76. The screw rod 73 is connected to the nut 75 on the sliding seat 72. The forward and reverse rotation of the screw rod 73 is controlled by the adjusting motor 75 to realize the adjustment of the distance between the two dispensing stations 2 to meet the dispensing requirements of material strips 001 of different widths.

[0026] like Figure 3 , 5 As shown, when the length of the dispensing station 2 is too long, in order to ensure the stability of the dispensing station 2 during the spacing adjustment, this embodiment adopts when the first fixed seat 71, the sliding seat 72, and the screw rod 73 are multiple groups, one end of which is connected to the adjusting motor 76, and the other end is connected to the remaining screw rods 73 through the second synchronous belt 77.

[0027] Multiple first fixed seats 71 are fixed at the bottom of the same dispensing platform 2, and multiple sliding seats 72 are fixed at the bottom of another dispensing platform 2. Each first fixed seat 71 and sliding seat 72 is connected to a wire rod 73, one of which is connected to the adjusting motor 76, and the remaining wire rods 73 are connected to the wire rod 73 through a second synchronous belt 77. In this way, multiple sliding seats 72 can synchronously approach or move away from multiple corresponding first fixed seats 71, thereby realizing the adjustment of the distance between the two dispensing platforms 2.

[0028] like Figure 6As shown, in some embodiments, due to the change in the distance between the two dispensing stations 2, the lifting support seat 5 is not located at the midpoint of the gap between the two dispensing stations 2. In order to solve the above problem, in this embodiment, a third slide rail 51 is also fixed on the machine base 1, and the length direction of the third slide rail 51 is perpendicular to the length direction of the dispensing station 2; the bottom of the slide seat 52 is slidably arranged on the third slide rail 51; the second cylinder 53 is fixed on the slide seat 52, and a lifting part 54 is arranged at the output end of the second cylinder 53, and the lifting support seat 5 is arranged on the top of the lifting part 54; In this way, the lifting support seat 5 can move perpendicular to the length direction of the dispensing platform 2, and then the lifting support seat 5 is set at the midpoint of the two dispensing platforms 2; the lifting and lowering of the lifting support seat 5 is controlled by the second cylinder 53, and the second cylinder 53 is fixed on the slide seat 52. When the second cylinder 53 works, it drives the lifting part 54 and the lifting support seat 5 to rise.

[0029] like Figure 6 As shown, in some embodiments, in order to ensure that the lifting support seat 5 only performs lifting movement and prevent the lifting support seat 5 from rising excessively and causing the material belt 001 to bend upward, a guide seat 55 is also fixed on the slide seat 52 in this embodiment; a guide rod 56 cooperating with the guide seat 55 is arranged at the bottom of the lifting part 54; height limiting rods 57 are arranged on both sides of the top of the lifting part 54, and the length direction of the height limiting rod 57 is perpendicular to the length direction of the dispensing table 2; buffer members 58 are arranged at both ends of the top of the height limiting rod 57 to abut against the bottom of the dispensing table 2; In this embodiment, the two guide seats 55 cooperate with the corresponding guide rods 54 to realize that the lifting support seat 5 can only perform lifting movement; a height limiting rod 57 and a buffer member 58 are set. When the buffer member 58 is against the bottom of the dispensing table 2, the height limiting rod 57 is in the upper limit state, which prevents the lifting support seat 5 from continuing to rise and damaging the material belt 001.

[0030] like Figure 1 As shown, when the material strip 001 bends upward, the present embodiment uses a capture camera 8 disposed above the dispensing station 2, which is suitable for detecting and recording the upward bending state of the middle part of the material strip 001; The capture camera 8 is arranged above the material strip 001. When the material strip 001 bends upward, the capture camera 8 will capture and mark the terminals at the material strip 001 without performing glue dispensing. The terminals will be processed after subsequent rewinding.
