Description

Technical Field

[0001] The invention belongs to the technical field of circuit board dust sticking equipment, and in particular relates to a dust sticking machine and a dust sticking paper roll component and a dust sticking roller component thereon. Background Art

[0002] The dust collecting machine is a special equipment customized for the current circuit board industry. When testing the circuit board, it needs to pass through the dust collecting machine for dust collection. However, some circuit boards have seesaw phenomenon at the edges, which causes the thickness of each circuit board to have certain fluctuations. In the existing dust collecting machine, the gap size of the circuit board dust collecting channel is fixed. When testing the circuit board with warped edges, it is easy to cause the board to get stuck.

[0003] At the same time, the existing dust sticking machine is not convenient for replacing the dust sticking paper roll, and is not convenient for cleaning and replacing the dust sticking roller. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, one of the purposes of the present invention is to provide a dust collecting machine that can avoid the phenomenon of circuit boards being stuck when they are fed into the circuit board.

[0005] The present invention solves the above-mentioned first object of the invention, and the technical solution adopted is:

[0006] A dust sticking machine comprises a box frame, an upper dust sticking roller assembly, a lower dust sticking roller assembly, an upper dust sticking paper roll assembly, and a transmission assembly;

[0007] The lower dust sticking roller assembly is fixed on the box frame, and a guide rail device is provided on the lower dust sticking roller assembly; the upper dust sticking roller assembly is slidably connected with the lower dust sticking roller assembly through the guide rail device, and the upper dust sticking roller assembly can be close to the lower dust sticking roller assembly or far away from the lower dust sticking roller assembly; the gap between the upper dust sticking roller assembly and the lower dust sticking roller assembly is a dust sticking channel for the circuit board;

[0008] The upper sticky paper roll assembly is located above the upper sticky roller assembly, and the upper sticky paper roll assembly is provided with an upper paper roll cylinder for sticking dust; the upper sticky paper roll assembly can be fixed on the box frame in an upward and downward manner;

[0009] When the upper sticky paper roll assembly is pressed downward, the upper sticky paper roll assembly abuts against the upper sticky roller assembly and drives the upper sticky roller assembly to move downward along the guide rail device, so that the sticky roller of the upper sticky roller assembly can stick to the circuit board, and at the same time, the upper paper roll can stick to the sticky roller of the upper sticky roller assembly; the reset device is used to reset the upper sticky roller assembly when the upper sticky paper roll assembly is away from the upper sticky roller assembly;

[0010] The transmission assembly is used for transmission connection with the lower dust sticking roller assembly and / or the upper dust sticking roller assembly to drive the circuit board to move at the circuit board dust sticking channel.

When one side edge of the circuit board enters the circuit board dust sticking channel, the upper dust sticking paper roll assembly presses down, driving the upper dust sticking roller assembly to press down. At this time, regardless of whether the circuit board has warped, the upper dust sticking roller assembly directly presses down on the upper side of the circuit board, thus preventing the phenomenon of card board. While the upper dust sticking roller assembly and the lower dust sticking roller assembly are sticking dust on the circuit board, the upper paper roll cylinder of the upper dust sticking paper roll assembly also contacts and sticks dust with the dust sticking roller of the upper dust sticking roller assembly; when the circuit board has finished sticking dust and the upper dust sticking paper roll assembly moves up, the upper dust sticking roller assembly resets under the action of the reset device.

In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0050] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0051] Such as Figure 1-15As shown in the figure, a dust sticking machine includes a box frame 1, an upper dust sticking roller assembly 2, a lower dust sticking roller assembly 3, an upper dust sticking paper roll assembly 4, and a transmission assembly 6;

[0052] The lower dust sticking roller assembly 3 is fixed on the box frame 1, and a guide rail device 5 is provided on the lower dust sticking roller assembly 3; the upper dust sticking roller assembly 2 is slidably connected to the lower dust sticking roller assembly 3 through the guide rail device 5, and it is possible for the upper dust sticking roller assembly 2 to be close to or away from the lower dust sticking roller assembly 3; the gap between the upper dust sticking roller assembly 2 and the lower dust sticking roller assembly 3 is the circuit board dust sticking channel;

[0064] The first lower dust sticking roller 34 and the second lower dust sticking roller 35 are arranged in parallel on the same horizontal plane; the lower conveying roller shaft 36 is located between the first lower dust sticking roller 34 and the second lower dust sticking roller 35; dust sticking rubber sleeves for sticking dust are sleeved on the first lower dust sticking roller 34 and the second lower dust sticking roller 35 at intervals; a transition wheel piece 361 for preventing clamping is arranged on the lower conveying roller shaft 36, and the transition wheel piece 361 is arranged corresponding to the intervals of the dust sticking rubber sleeves; the first lower conveying wheel piece shaft 37 is arranged on one side of the first lower dust sticking roller 34 away from the lower conveying roller shaft 36; the second lower conveying wheel piece shaft 38 is arranged on one side of the second lower dust sticking roller 35 away from the lower conveying roller shaft 36; the conveying wheel pieces 362 arranged on the first lower conveying wheel piece shaft 37 and the second lower conveying wheel piece shaft 38 are arranged corresponding to the intervals of the dust sticking rubber sleeves;

[0065] Both of the two lower dust sticking roller bearing seats 31 are fixed on the inner slide rail of the lower dust sticking roller pull-out slide rail 32, and the outer slide rail of the lower dust sticking roller pull-out slide rail 32 is fixedly connected to the box body frame 1; a lower dust sticking roller pulling device 33 for pulling out the lower dust sticking roller assembly 3 is connected to one of the lower dust sticking roller bearing seats 31.

[0066] The above technical solution is a setting mode of the lower dust sticking roller assembly 3. The lower dust sticking roller assembly 3 can be pulled out through the lower dust sticking roller pulling device 33, so as to clean and replace the dust sticking roller. For the convenience of replacement, the main shaft of the dust sticking roller can be installed and connected by a coupling that is convenient for disassembly and assembly; as Figure 7 and Figure 8 shown, a transmission wheel of the transmission assembly can be arranged at one end of the lower dust sticking roller assembly 3 away from the lower dust sticking roller pulling device 33. Specifically, in the embodiment of Figure 8 , it is a magnetic transmission wheel.

[0067] Combined with Figure 9As shown, in some embodiments, the upper dust adhering roller assembly 2 includes two upper dust adhering roller bearing seats 21, and a first upper dust adhering roller 22, a second upper dust adhering roller 23, an upper conveying roller shaft 24, a first upper conveying wheel piece shaft 25, and a second upper conveying wheel piece shaft 26 rotatably installed between the two upper dust adhering roller bearing seats 21; the first upper dust adhering roller 22 and the second upper dust adhering roller 23 are arranged in parallel on the same horizontal plane; the upper conveying roller shaft 24 is located between the first upper dust adhering roller 22 and the second upper dust adhering roller 23; dust adhering rubber sleeves for adhering dust are sleeved on the first upper dust adhering roller 22 and the second upper dust adhering roller 23 at intervals; a transition wheel piece for preventing clamping is arranged on the upper conveying roller shaft 24, and the transition wheel piece is arranged corresponding to the intervals of the dust adhering rubber sleeves; the first upper conveying wheel piece shaft 25 is arranged on one side of the first upper dust adhering roller 22 away from the upper conveying roller shaft; the second upper conveying wheel piece shaft 26 is arranged on one side of the second upper dust adhering roller 23 away from the upper conveying roller shaft 24; an electromagnet adsorption block 27 for magnetically adsorbing and connecting with the upper dust adhering paper assembly 4 and having a positioning function is arranged on the upper dust adhering roller bearing seat 21. The electromagnet adsorption block 27 in this embodiment is an implementation manner of the reset device; when the electromagnet adsorption block 27 is adsorbed to the upper dust adhering paper assembly 4, a magnetically adsorbed connection is formed. After the upper dust adhering roller assembly 4 is pressed close to the upper dust adhering roller assembly 2, under the action of magnetic force, the two assemblies are magnetically adsorbed together; when displaced in the up and down direction, the upper dust adhering roller assembly 4 and the upper dust adhering paper assembly 2 can be synchronized; at the same time, this magnetically adsorbed connection can be disassembled and separated under the action of an external force, so it does not prevent the upper dust adhering paper assembly 4 from being set in a pulling mode. In some embodiments, the upper dust adhering paper assembly 4 can be set in a pulling mode; however, the present application is not limited thereto, and in some embodiments, it may not be set in a pullable mode either.

[0068] Combined Figure 3 、 4 、7, 9 As shown, in some embodiments, the guide rail device 5 includes a lower guide rail connection seat 51, a linear guide rail 53, and an upper guide rail connection seat 52; the lower guide rail connection seat 51 is fixed on the inner side surface of the lower dust adhering roller bearing seat 31; the upper guide rail connection seat 52 is correspondingly fixed on the inner side surface of the upper dust adhering roller bearing seat 21; linear guide rail mounting holes are provided on both the lower guide rail connection seat 31 and the upper guide rail connection seat 21; one end of the linear guide rail 53 is fixedly connected to the lower guide rail connection seat 31 or the upper guide rail connection seat 21, and the other end of the linear guide rail 53 is slidably connected to the upper guide rail connection seat 21 or the lower guide rail connection seat 31; when an external force pulls out the lower dust adhering roller assembly 3 through the lower dust adhering roller pulling device 33, it is possible for the upper dust adhering roller assembly 2 to be pulled out of the box body frame 1 synchronously through the limit of the guide rail device 5.

[0069] This is an implementation of the guide rail device 5. In some embodiments, a compression spring (not shown in the figure) can be sleeved on the linear guide rail 53 between the upper and lower guide rail connectors 52, 52 of the guide rail device 5, so as to form a simple reset device. Of course, the compression spring here or the magnetic adsorption connection method with the electromagnet adsorption block 27 described above can be set simultaneously or only one of them can be adopted; the magnetic adsorption connection method also has a positioning function, which is convenient for aligning the upper dust sticking paper assembly 4 and the upper dust sticking roller assembly 2. Sleeving a compression spring on the linear guide rail 53 also has a buffering function.

[0070] As Figure 11-13 shown, in some embodiments, one end of the lower dust sticking roller assembly 3 and the upper dust sticking roller assembly 2 away from the lower dust sticking roller pulling device 33 is a magnetic wheel drive connection end. The magnetic wheel drive connection end, that is, the end for setting the magnetic wheel assembly, its drive mode belongs to magnetic wheel drive; magnetic wheel drive is a setting method of the drive assembly. The drive mode of the magnetic wheel is prior art, but in this application, by adopting the magnetic wheel drive mode and applying it to the dust sticking machine field, the noise of the dust sticking machine can be reduced, the service life can be enhanced. At the same time, it should be noted that the magnetic wheel drive is a non-contact drive mode. Therefore, by adopting the magnetic wheel drive, it is more convenient to set the upper dust sticking roller assembly 2 and the lower dust sticking roller assembly 3 into a pull-out mode, so as to facilitate the replacement and cleaning of the dust sticking rollers.

[0071] Combined with Figure 13 、 15 shown; in some embodiments, an electrostatic eliminator rod for removing the static electricity of the circuit board is provided on the upper side and / or the lower side at the entrance of the circuit board dust sticking channel. The electrostatic eliminator rod can be fixed on the box frame 1. When the circuit board enters the dust sticking channel, the circuit board is de-electrified, so that the dust sticking is more thorough and the dust sticking effect is better; electrostatic eliminator rods 8 are arranged on both the upper and lower sides at the entrance of the dust sticking channel, and the electrostatic elimination effect is better.

[0072] The second object of the invention of this application: to provide an upper dust sticking paper assembly 4, which can be used in the above-mentioned dust sticking machine; at the same time, the upper dust sticking paper assembly 4 can also be pulled out of the box frame of the dust sticking machine to facilitate the replacement of the dust sticking paper roll.

[0073] Combined with Figure 1 、 3, as shown in Figures 5, 10 - 13, a top dust - sticking roll paper assembly 4 is illustrated, which can be used in the above - mentioned dust - sticking machine. It includes a top roll paper cylinder 41, a top adjustment positioning block 42, a top positioning plate 43, a top pull - out slide rail 44, a top handle device 45, a top paper cylinder lifting cylinder 46, and a top dust - sticking assembly lifting cylinder 47. The two ends of the top roll paper cylinder 41 are respectively rotatably connected to the top adjustment positioning block 42. The top adjustment positioning block 42 is slidably connected to the top positioning plate 43 through a crossed roller guide and can move up and down. The top positioning plate 43 is fixed on the inner slide rail of the top pull - out slide rail 44, and the outer slide rail of the top pull - out slide rail 44 is fixedly connected to the telescopic rod of the top dust - sticking assembly lifting cylinder 47. The main body of the top dust - sticking assembly lifting cylinder 47 is fixed on the box - body frame 1. The top paper cylinder lifting cylinder 46 is fixed on the box - body frame 1 and is used to control the top adjustment positioning block 42 to move downward so that the top roll paper cylinder 41 performs dust - sticking on the dust - sticking roller of the top dust - sticking roller assembly 2. A top dust - sticking roller pressing block 431 is provided at the lower end of the top positioning plate 43. The top dust - sticking roller pressing block 431 is used to abut against the top dust - sticking roller assembly 2 when the top positioning plate 43 presses down to provide a pressing force for the top dust - sticking roller assembly 2 to move downward. A compression spring 421 for providing a restoring force for the top adjustment positioning block 42 is provided between the top adjustment positioning block 42 and the top dust - sticking roller pressing block 431. A top handle device 45 for pulling out the top roll paper cylinder from the box - body frame to facilitate the replacement of the top roll paper cylinder is connected to the top positioning plate 43.

[0074] In this embodiment, the top dust - sticking assembly lifting cylinder 47 controls the entire top dust - sticking roll paper assembly 4 to move up and down. Before the circuit board enters the dust - sticking machine, the top dust - sticking roll paper assembly 4 needs to be lifted. After one side edge of the circuit board enters, it is pressed down. This makes the use somewhat inconvenient. In order to more conveniently and continuously perform dust - sticking on the circuit board, there is the following embodiment;

[0075] In some embodiments, a connecting bottom plate 48 is fixedly connected to the inner slide rail of the top pull - out slide rail 44. One side of the top positioning plate 43 close to the top roll paper cylinder 41 is connected to the connecting bottom plate 48 through a linear slide rail and can float up and down. The top adjustment positioning block 42 is arranged on the side of the top positioning plate 43 far from the connecting bottom plate 48. Both the connecting bottom plate 48 and the top positioning plate 43 are provided with hollow parts for the connecting shaft between the top adjustment positioning block 42 and the top roll paper cylinder 41 to perform up - and - down displacement. One end of a tension spring 431 is connected to the top positioning plate 43, and the other end of the tension spring 431 is connected to the upper part of the connecting bottom plate 48 (specifically, such as Figure 12As shown in the figure, a tension spring 431 can be installed by arranging a tension spring connecting rod on the upper positioning plate 43 and the connecting bottom plate 48; the tension spring 431 is used to provide a restoring force for the upper positioning plate 43; a sucker electromagnet for magnetically adsorbing and connecting with the upper dust-removing roller assembly is arranged on the upper positioning plate. As described above, an electromagnet adsorption block 27 corresponding to the sucker electromagnet 431 is arranged on the upper dust-removing roller assembly 2. In this embodiment, the upper positioning plate 43 is connected to the connecting bottom plate 48 through a linear slide rail so as to be floating up and down. In this way, the upper positioning plate 43 has the function of floating up and down. When the circuit board enters the board, the upper dust-removing roller assembly 2 can also float up and down, so that the board can enter more stably and smoothly without always controlling the lifting cylinder 47 of the upper dust-removing assembly to lift the entire upper dust-removing roll paper assembly 4; it is more convenient to use; the structure is more stable. When the lifting cylinder 47 of the upper dust-removing assembly controls the entire upper dust-removing roll paper assembly 4 to press down, this floating structure can also generate a buffering force.

[0076] In some embodiments, the upper paper cylinder lifting cylinder 46 can be as Figure 13 shown, set as a single lifting cylinder 46, and the cylinder expansion rod transmits power to the upper adjusting positioning block 42 through a Z-shaped steel frame; however, in this setting method, the stroke of the upper paper cylinder lifting cylinder 46 is very long; therefore, in some embodiments, the method shown in Figure 12 can be adopted, that is, a setting method of multiple upper paper cylinder lifting cylinders 46 is adopted. The expansion rod of the first upper paper cylinder lifting cylinder 46 is connected to one end of the Z-shaped steel frame 461; the other end of the Z-shaped steel frame 461 is fixed to the second upper paper cylinder lifting cylinder 46, and the expansion rod of the second paper cylinder lifting cylinder 46 directly drives the upper adjusting positioning block 42; in this way, two cylinders are set, and the stroke of a single cylinder can be shorter; therefore, there is no need to set a long cylinder, and in this case, the overall height of the dust-removing machine can be reduced. Of course, in some embodiments, the overall height of the dust-removing machine can also be reduced through other structural settings.

[0077] The third object of the present invention: Provide a dust-removing roller assembly that can be used in the above-mentioned dust-removing machine and can be pulled out of the dust-removing machine box frame to facilitate cleaning or replacing the dust-removing roller.

[0078] The dust-removing roller assembly of the third object of the present invention is composed of the upper dust-removing roller assembly 2 and the lower dust-removing roller assembly 3 in the above text; the structures of the upper dust-removing roller assembly 2 and the lower dust-removing roller assembly 3 will not be described repeatedly here.

[0079] Based on the above-mentioned ideal embodiments of the present invention as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
