Description

TECHNICAL FIELD

[0001] The utility model relates to electronic component production field especially a conveying belt special for electronic components. BACKGROUND

[0002] The conveying belt is continuously rubbed in the use process, and the rubbing can make the surface of the conveying belt gradually abraded, and the abrasion leads to the increase of the surface roughness of the conveying belt, further leads to the increase of the friction coefficient, further accelerates the abrasion and reduces the service life of the conveying belt, so the conveying belt needs to be oiled and maintained every 3 months.

[0003] In other industries, the shutdown maintenance of the conveying belt can reduce the conveying capacity, so that the product output per unit time decreases. But in the electronic industry, this defect is particularly obvious. Because the electronic components are very small in size, the number of electronic components that can be loaded on the conveying belt per unit area is more, which leads to a large conveying capacity of the conveying belt, so when the conveying belt is shutdown for maintenance, the output rate of the electronic industry decreases several times or even dozens of times more than that of other industries, and thus many manufacturers choose to reduce the maintenance frequency in order not to reduce the output efficiency, which leads to the reduction of the service life of the conveying belt.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] For example, Figure 1The illustrated conveyor belt for electronic components includes conveyor wheels 2 mounted at both ends of a support frame 1 and a belt 3 wound around the conveyor wheels 2. One conveyor wheel 2 is a drive wheel, driven by a motor to rotate and rotate the belt 3. The other conveyor wheel 2 is a driven wheel that operates in conjunction with the belt. The upper part of the support frame 1 is the transport side of the belt 3, used for conveying electronic components, while the lower part of the support frame 1 is the rotation side of the belt 3. On the transport side, multiple support rollers 4 are mounted on the support frame 1 to support the belt 3. The two ends of the support rollers 4 are mounted on the support frame 1 via bearing seats.

[0019] Two first reversing pulleys 5 are symmetrically arranged on the rotating side of the belt 3. The first reversing pulleys 5 are mounted on the lower side of the belt 3, causing the belt 3 to rotate 90° in its extension direction, thus extending the belt 3 downwards. Two second reversing pulleys 6 are symmetrically arranged between the two first reversing pulleys 5. The second reversing pulleys 6 are mounted on the upper side of the belt 3, causing the belt 3 to rotate 90° in its extension direction. This creates a downwardly protruding portion on the rotating side of the belt 3 through the first reversing pulleys 5 and the second reversing pulleys 6, providing installation space for the roller coating device 7.

[0020] A roller coating device 7 is installed on the belt 3 between the two second reversing pulleys 6. For example... Figure 2 As shown, the roller coating device 7 includes a vertical plate 8 fixed to a support frame 1. A horizontal plate 9 is horizontally fixed to the bottom of the vertical plate 8. The horizontal plate 9 has a threaded hole with internal threads, into which a threaded adjusting rod 10 with external threads is screwed. The lower end of the threaded adjusting rod 10 is rotatably connected to an upper housing 11. A lower housing 12 is connected below the upper housing 11 at a distance greater than the thickness of the belt 3. An upper roller 13 is mounted on the bottom surface of the upper housing 11, and a lower roller 14 is mounted on the top surface of the lower housing 12. Because the threaded adjusting rod 10 is threadedly connected to the horizontal plate 9, it can move up and down relative to the horizontal plate 9 when it rotates. Therefore, by rotating the threaded adjusting rod 10, the height of the roller coating device 7 can be changed, allowing the upper roller 13 to contact the belt 3 or the lower roller 14 to contact the belt 3.

[0021] The upper box 11 and the lower box 12 are connected by a side plate 15, so that the upper box 11 and the lower box 12 are relatively fixed. When the roller coating device 7 rises, the lower roller 14 can contact the outer surface of the belt 3. When the roller coating device 7 descends, the upper roller 13 can contact the inner surface of the belt 3.

[0022] like Figure 3As shown, the upper roller 13 is provided with a conveying pipe 16 located in the upper box 11, and a nozzle 17 is arranged on the conveying pipe 16 and faces the upper roller 13. The conveying pipe 16 is provided with an inlet on the side of the upper box 11, and the conveying pipe 16 can be supplied with maintenance oil. The nozzle 17 sprays the maintenance oil to the upper roller 13, so that the maintenance oil can be coated on the inner surface of the belt 3 through the upper roller 13, and the belt 3 is maintained to prolong the service life of the belt 3. The number of the upper roller 13 is at least one, the adjacent two upper rollers 13 are in contact with each other, and the nozzle 17 is located between the adjacent two upper rollers 13.

[0023] The lower roller 14 is provided with a tray 18 located in the lower box 12, and part of the lower roller 14 is located in the tray 18. The lower box 12 is provided with an injection pipe 19, and the outlet of the injection pipe 19 is located above the tray 18. The inlet of the injection pipe 19 is located on the side of the lower box 12, and the injection pipe 19 can be injected with maintenance oil. The maintenance oil is injected into the tray 18 through the injection pipe 19 and forms a certain height of liquid level. The lower vertex of the lower roller 14 is always lower than the liquid level in the tray 18, so that the roller surface of the lower roller 14 can be coated with the maintenance oil when the lower roller 14 rotates and the outer surface of the belt 3 is maintained to prevent the belt 3 from cracking.

[0024] Preferably, the number of the lower roller 14 is at least one, and the plurality of lower rollers 14 are arranged side by side.

[0025] The amount of oil coated on the upper roller 13 and the lower roller 14 can be controlled by controlling the flow of the nozzle 17 and the height of the liquid level in the tray 18.

[0026] Preferably, the belt 3 is provided with two clamping wheels 20 arranged in an upper and lower distribution on both sides of the roller coating device 7, and the belt 3 is located between the two clamping wheels 20. The clamping wheels 20 are used to maintain the height of the belt 3 and prevent the belt 3 from deforming or shifting up and down due to the action force of the roller coating device 7.

[0027] When the conveying belt works, the roller coating device 7 can be lifted and lowered by rotating the threaded adjusting rod 10, and the conveying belt does not stop during the process. During the process, the height of the roller coating device 7 can be adjusted so that the belt 3 does not contact the upper roller 13 or the lower roller 14. At this time, the roller coating device 7 does not work because it does not contact the belt 3. When maintenance is needed, the height of the roller coating device 7 can be adjusted to lower so that the upper roller 13 just contacts the belt 3 without generating a large action force on the belt 3. At this time, the upper roller 13 rotates to coat the maintenance oil on the belt 3 through the upper roller 13. Or the height of the roller coating device 7 can be adjusted to rise so that the lower roller 14 just contacts the belt 3 without generating a large action force on the belt 3. At this time, the lower roller 14 rotates to coat the maintenance oil on the belt 3 through the lower roller 14.

[0028] It is obvious for those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, but that it can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and are not limiting in any way.
