Description

Technical Field

[0001] The invention relates to a coating device for applying liquid adhesive to screws that move in sequence. Background Art

[0002] In the prior art, one of the manufacturing processes for manufacturing screws with specific anti-leakage or anti-loosening functions is to apply a glue with specific anti-leakage or anti-loosening functions on the screw threads. Such glue has a certain viscosity. When performing a large number of screw gluing operations, in order to save costs and ensure uniform quality, the prior art has used an automatic gluing manufacturing machine to arrange the screws and then automatically move them to the gluing mechanism in sequence for gluing. The gluing area of ​​the screw threads includes full circumference gluing, half circumference gluing or specific area gluing, so that the screws can obtain the set tightness or combination fixing strength after assembly.

[0003] In order to increase the production speed of such leak-proof and loose-proof screws, the arranged screws are sequentially moved through a container containing liquid glue. At this time, the liquid glue with a higher viscosity in the container slightly protrudes from the opening above the container so that the threaded portion of the screw passing through the container can be adhered to the glue. At this time, the thicker liquid glue will form resistance to the moving screws, thereby causing the screws to swing and deflect irregularly or be pushed to the position of other moving screws. Therefore, when the screws cannot be stably shifted, the glue quality of the screws with specific leak-proof or loose-proof functions produced will be poor. Summary of the invention

[0024] See also Figure 1 and Figure 2 As shown, the liquid glue coating device of the present invention includes a pressure transmission group 10, a glue box 20 and a guide group 30, wherein the pressure transmission group 10, the glue box 20 and the guide group 30 are installed on a frame, and the frame is a frame of the prior art, wherein the glue box 20 is located on the side of the pressure transmission group 10, and the guide group 30 is located above the pressure transmission group 10.

[0025] The pressing transmission group 10 has a belt lining 11, a driving wheel 12, a driven wheel 13 and a rolling belt 14. The belt lining 11 can be a plate body. The driving wheel 12 and the driven wheel 13 are arranged on the plate body of the belt lining 11 at intervals. The driving wheel 12 and the driven wheel 13 can rotate relative to the plate body of the belt lining 11. In a specific embodiment, the driving wheel 12 is driven to rotate by a driving member. The aforementioned driving member can be a motor used in the prior art. The motor is installed on a frame, and the rotation center of the driving wheel 12 is connected and fixed to the corresponding motor power output shaft;

[0026] The rolling belt 14 is an elastic endless belt body, which can be assembled and sleeved between the driving wheel 12 and the driven wheel 13. The top end surface of the belt lining plate 11 has an upper arc guide surface 111, which has a concave arc surface and is located between the driving wheel 12 and the driven wheel 13. In addition, the bottom end surface of the belt lining plate 11 can also have a lower arc guide surface 112, which has an arc convex surface. One side of the rolling belt 14 assembled between the driving wheel 12 and the driven wheel 13 is not attached to the upper arc guide surface 111, and is suspended between the driving wheel 12 and the driven wheel 13, and the other side is attached to the lower arc guide surface 112. The rolling belt 14 can be driven by the driving wheel 12 to rotate and move, and the driven wheel 13 will rotate at the same time. Furthermore, the driving wheel 12 can be connected to a control unit, which is a prior art. The control unit can control and adjust the rotation speed of the connected driving wheel 12, thereby controlling and adjusting the moving speed of the rolling belt 14.

[0027] Also see Figure 2 , Figure 3 and Figure 4 As shown, the glue box 20 is a hollow box body with an opening 21 formed on the top, and the opening 21 is facing upward. The box body of the glue box 20 is assembled on the side wall of the belt lining plate 11 and is adjacent to the rolling belt 14. The box body of the glue box 20 can be filled with liquid glue. Since the liquid glue is relatively thick, it can slightly protrude above the opening 21 of the box body. Furthermore, an adjustment mechanism can be provided between the glue box 20 and the plate body of the belt lining plate 11 to adjust the position of the glue box 20 relative to the plate body, that is, to adjust the position of the liquid glue. The aforementioned adjustment mechanism is a prior art, so it is not described in detail and is not shown in the figure.

[0028] See also Figure 1 , Figure 3 and Figure 4 As shown, the guide assembly 30 comprises a guide plate 31, a driven rotating plate 32, a plurality of magnets 33 and a bayonet assembly 34. The guide plate 31 is a disc body, and a ring groove 311 is formed inwardly on the circumferential surface of the disc body. Through the ring groove 311, two sides of the disc body of the guide plate 31 are respectively formed into a first ring piece 312 and a second ring piece 313, wherein the outer diameter of the first ring piece 312 is greater than the outer diameter of the second ring piece 313, and the outer edge surface of the first ring piece 312 is formed inwardly with a plurality of positioning holes 314, each of which is in a concave arc shape and is arranged at intervals, and each positioning hole 314 can accommodate and convey a screw 40 to be processed;

[0029] The driven turntable 32 can be a hollow disk and is sleeved on the annular groove 311 of the guide plate 31. The driven turntable 32 and the guide plate 31 have the same rotation center. The driven turntable 32 can be freely rotated on the guide plate 31. The rotation center of the guide plate 31 is driven to rotate by a driving member 35. The aforementioned driving member 35 can be a motor used in the prior art. The motor is mounted on the frame. The arc shape of the driven turntable 32 is consistent with the concave arc surface of the upper guide arc surface 111 of the belt lining plate 11. Figure 5 and Figure 6 As shown, the outer edge surface of the driven rotating disk 32 may be adjacent to the arc hole surface of each positioning hole 314. As shown in one preferred embodiment of the figure, the outer edge surface of the driven rotating disk 32 is tangent to the extended surface of the arc hole surface of each positioning hole 314. Furthermore, each magnet 33 is mounted on the first ring plate 312 of the guide plate 31, and each magnet 33 corresponds to each positioning hole 314.

[0030] See also Figure 7 and Figure 8 As shown, the guide plate 31 is provided with a first pin hole 315 at the non-rotation center position, and the driven rotating plate 32 is provided with a second pin hole 321 at the non-rotation center position. The first pin hole 315 and the second pin hole 321 can be aligned with each other. The hole shape of the first pin hole 315 and the second pin hole 321 is a convex shape as shown in one specific embodiment of the figure;

[0031] The latch assembly 34 includes a rod body 340, a spring 343 and a baffle 344. The rod body 340 is a long rod, one end of which has a rod head 341 protruding, and the other end of which has a protruding block 342 protruding radially from the circumference. The baffle 344 is a hollow ring. The spring 343 and the baffle 344 can be sleeved on the rod body 340. One end of the spring 343 abuts against the rod head 341, and the other end abuts against one side of the baffle 344. The other side of the baffle 344 is abutted by the protruding block 342.

[0032] See also Fig. 9 As shown, the first pin hole 315 of the guide plate 31 and the second pin hole 321 of the driven rotating plate 32 are aligned with each other, and the rod body 340 has an end portion of the protrusion 342 that penetrates the first pin hole 315 and the second pin hole 321, and the blocking piece 344 abuts against one side of the guide plate 31. After compressing the spring 343, the end with the protrusion 342 can pass through the other side of the guide plate 31. When the rod body 340 is rotated, the protrusion 342 can be stuck against the other side of the guide plate 31, and at this time, the guide plate 31 and the driven rotating plate 32 can be combined with each other.

[0033] The guide assembly 30 is assembled above the pressing transmission assembly 20, wherein the driven turntable 32 corresponds to the rolling belt 14, so that the rolling belt 14 can be pressed against the outer edge of the driven turntable 32 relative to the side of the upper guide arc surface 111, and the screw 40 to be processed is located in the positioning hole 314 and can be sucked and fixed by the magnet 33, but the screw 40 can still be rotated in the positioning hole 314. When the guide plate 31 rotates, each of the screws 40 located in each of the positioning holes 314 can be transferred to the belt lining 11 of the pressing transmission assembly 10. At this time, each of the moving screws The wire 40 contacts the rolling belt 14 to form a non-rotating translation or generate self-rotation. In addition, each of the screws 40 to be processed located in the positioning hole 314 is pushed down by the outer edge of the driven turntable 32 located above, in addition to being pushed upward by the rolling belt 14. This ensures the displacement of each screw 40. Furthermore, the driving wheel 12 can be adjusted to rotate so that the rolling belt 14 can rotate, and the rotation speed of the rolling belt 14 and the rotation speed of the guide plate 31 can be adjusted to control the self-rotation speed of the screw 40.

[0034] Also see Figure 8 , Fig.10 and Fig.11 As shown, the bayonet assembly 40 is removed from the guide disk 31 and the driven disk 32, so that the guide disk 31 and the driven disk 32 can rotate relative to each other. When the moving speed of the rolling belt 14 driven by the driving wheel 12 is greater than the tangential speed of the guide disk 31, the screw 40 will rotate and move over the glue box 20. The driven disk 32 abuts against each of the screws 40. The screw 40 can make the driven disk 32 passively rotate relative to the guide disk 31. When the thread of each of the screws 40 passes through the opening 21 and contacts the liquid glue, the entire circumference of the thread can be adhered to the liquid glue to complete the gluing operation on the entire circumference, and the finished product of each of the screws 40 that has been glued can be taken out to proceed to the next process. In addition, since each of the screws 40 will form resistance to the moving and rotating screws 40 when in contact with the liquid glue, each of the screws 40 is abutted by the driven disk 32 and the rolling belt 14, as shown in FIG. Figure 6 As shown, the displacement during rotation can still be improved to improve the quality of the screws produced.

[0035] See also Fig. 9 , Fig.10 and Fig.11As shown, when the present invention implements 1 / 2 circumference gluing or 3 / 4 circumference gluing, the first pin hole 315 of the guide plate 31 is aligned with the second pin hole 321 of the driven turntable 32 to be inserted and positioned in combination with the bayonet group 40, and the moving speed of the rolling belt 14 is adjusted and controlled to be constant with the tangential speed of the guide plate 31. At this time, each screw 40 can translate through the opening 21 of the glue box 20 without rotating and contact with the liquid glue. When the glue liquid level in the glue box 20 is adjusted to be located at 1 / 2 diameter of the screw 40, 1 / 2 circumference gluing can be implemented on the threads of each screw 40. Furthermore, when the glue liquid level in the glue box 20 is adjusted to be located at 3 / 4 diameter of the screw 40, 3 / 4 circumference gluing can be implemented on the threads of each screw 40.

[0036] As mentioned above, in addition to being able to adjust and control the speed of the rolling belt 14 and the guide plate 31, the present invention can also increase the speed of the rolling belt 14 and the guide plate 31 according to actual production capacity requirements to increase production capacity.

[0037] like Figure 1 As shown, the liquid glue coating device of the present invention can be further provided with a feeder 50 for implementation, and the feeder 50 has a vibration mechanism 51, and a feed track 52 is arranged above the vibration mechanism 51. The feed track 52 is arranged horizontally or slightly inclined horizontally, and one end thereof is a discharge end 521. This feeder 50 is a prior art and will not be further described. The specific embodiment shown in the figure is used for conveying a plurality of screws 40, each of the screws 40 is horizontally located on the feed track 52, and after the vibration mechanism 51 generates a vibration for conveying forward, each of the screws 40 can be moved forward in sequence for conveyance, and the discharge end 521 is located between the guide plate 31 and the belt lining plate 11, so that each of the screws 40 is conveyed into each of the positioning holes 314 and is adsorbed by the magnet 33 and is pushed upward by the rolling belt 14.
