Description

Technical Field

[0001] The present application relates to the field of glue dispensing technology, and in particular to a cleaning device and glue dispensing equipment. Background Art

[0002] Currently, the nozzle used in the underfill process is a flat nozzle, and its cleaning device is designed to clean glue residue on the nozzle during dispensing operations to prevent excessive glue residue on the nozzle from affecting the underfill quality. The cleaning method is to move the flat nozzle over the cleaning sponge until the two come into contact, then move the flat nozzle to the right, and clean through the rotational friction between the flat nozzle and the cleaning sponge. However, due to the upgrading of the underfill process, it is necessary to introduce a pointed nozzle. The previous nozzle cleaning device has poor cleaning effect, which will affect the quality of the underfill. There is also the risk of damage to the nozzle and the cleaning device, which will also increase the cost of fixture repair. Utility Model Content

DETAILED DESCRIPTION

[0028] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0030] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0031] like Figure 1 and Figure 2 As shown, the cleaning device according to the embodiment of the present application is used to clean the dispensing nozzle, including a driving component 10 and two wiping members 20, the wiping member 20 includes a fixed portion 21 and an elastic wiping portion 22 provided on the fixed portion 21, the wiping portion 22 is used to contact the dispensing nozzle, the driving component 10 is connected to the fixed portion 21 of at least one wiping member 20 and drives it to move so that the distance between the two wiping members 20 increases or decreases to squeeze the dispensing nozzle.

[0032] Specifically, the driving assembly 10 is in transmission connection with at least one wiper 20 to drive it to move. When the driving assembly 10 is in transmission connection with one wiper 20, for the convenience of description, one of the two wipers 20 is defined as the first wiper 20, and the other is defined as the second wiper 20. For example, when the driving assembly 10 is in transmission connection with the first wiper 20, it drives the first wiper 20 to approach or move away from the second wiper 20. When the dispensing nozzle moves to abut against the second wiper 20, the driving assembly 10 drives the first wiper 20 to approach the second wiper 20 until they jointly squeeze the dispensing nozzle. When the dispensing nozzle moves upward, the two wiping parts 22 generate frictional force on the dispensing nozzle, thereby achieving the effect of cleaning the dispensing nozzle. Since the wiping part 22 is elastic, when the two wiping parts 22 are squeezed, the wiping part 22 will deform by extrusion to wrap the dispensing nozzle, so as to ensure that all positions of the dispensing nozzle along the circumferential direction can be cleaned in place. At the same time, there is no need to repeatedly rub and wipe the dispensing nozzle, which can prevent the dispensing nozzle from being damaged. After the dispensing nozzle leaves the two wipers 20, the driving assembly 10 drives the first wiper 20 to move away from the second wiper 20 for the next cleaning of the dispensing nozzle.

[0033] Similarly, when the driving assembly 10 is in transmission connection with both wipers 20, it drives the two wipers 20 to approach or move away from each other. When the dispensing nozzle moves between the two wipers 20, the driving assembly 10 drives the two wipers 20 to approach each other until the two wipers 20 jointly squeeze the dispensing nozzle. When the dispensing nozzle moves upward, the two wiping parts 22 generate frictional force on the dispensing nozzle, thereby achieving the effect of cleaning the dispensing nozzle. Since the wiping part 22 is elastic, when the two wiping parts 22 are squeezed, the wiping part 22 will deform by extrusion to wrap the dispensing nozzle, so as to ensure that all positions of the dispensing nozzle along the circumferential direction can be cleaned in place. At the same time, there is no need to repeatedly rub and wipe the dispensing nozzle, which can prevent the dispensing nozzle from being damaged. After the dispensing nozzle leaves the two wipers 20, the driving assembly 10 drives the first wiper 20 to move away from the second wiper 20 for the next cleaning of the dispensing nozzle.

[0034] In the dispensing device provided by the embodiment of the present application, when the two wiping parts 22 are squeezed, the wiping part 22 will deform by extrusion to wrap the dispensing nozzle, so as to ensure that all positions of the dispensing nozzle along the circumferential direction can be cleaned in place. At the same time, there is no need to repeatedly rub and wipe the dispensing nozzle, which can prevent the dispensing nozzle from being damaged. After the dispensing nozzle leaves the two wipers 20, the driving assembly 10 drives the first wiper 20 to move away from the second wiper 20 for the next cleaning of the dispensing nozzle.

[0035] Among them, the driving assembly 10 driving the wiper 20 to move can be powered manually or by the device.

[0036] Such asFigure 2 As shown, in a specific embodiment, a base 30 is provided below the wiper 20.

[0037] As Figures 2 - 4 shown, for the cleaning device according to an embodiment of the present application, the driving assembly 10 includes a driving part 11 and a transmission group 12, and the driving part 11, the transmission group 12, and at least one fixing part 21 are sequentially connected in transmission.

[0038] Specifically, the driving part 11, the transmission group 12, and at least one fixing part 21 are sequentially connected in transmission. In this way, the fixing part 21 is driven by the power of the device, which is convenient for realizing automation and improving production efficiency and action rhythm.

[0039] As Figure 1 and Figure 2 shown, in some embodiments, the driving part 11 is configured as a cylinder group. The cylinder group includes a first piston 111 and a second piston 112. The first piston 111 is connected to one fixing part 21, and the second piston 112 is connected to another fixing part 21.

[0040] Among them, the cylinder group includes a first piston 111 and a second piston 112. The first piston 111 is connected to one fixing part 21, and the second piston 112 is connected to another fixing part 21. That is to say, the two fixing parts 21 are driven by the cylinder group, so that the two fixing parts 21 can approach or move away from each other, increasing the diversity of structural solutions and facilitating the user to select according to needs.

[0041] As Figures 3 - 5 shown, in some embodiments, the transmission group 12 includes a first transmission gear 121 and a transmission member 122 that mesh with each other. The driving part 11 is configured as a motor. The first transmission gear 121 is in transmission connection with the motor, and the transmission member 122 is connected to one fixing part 21. The transmission member 122 includes one of a rack and a screw.

[0042] The first transmission gear 121 is in transmission connection with the motor, and the transmission member 122 is connected to one fixing part 21. The first transmission gear 121 and the transmission member 122 mesh with each other. During the rotation of the first transmission gear 121, the transmission member 122 will be driven to rotate or move. Among them, the transmission member 122 includes one of a rack and a screw, so as to convert the rotational motion of the first transmission gear 121 into a linear motion of the fixing part 21, thereby realizing the approach or separation between the two fixing parts 21, increasing the diversity of structural solutions, and facilitating the user to select according to needs.

[0043] As Figure 3 and Figure 4As shown, in a specific embodiment, the transmission group 12 further includes a second transmission gear 123 , the second transmission gear 123 is connected to the output shaft of the motor, and the second transmission gear 123 is meshed with the first transmission gear 121 .

[0044] like Figure 6 and Figure 7 As shown, in some embodiments, a plurality of protrusions 221 are provided on a side of the wiping portion 22 facing away from the fixing portion 21 .

[0045] It is understandable that the wiping portion 22 is provided with a plurality of protrusions 221 on the side facing away from the fixing portion 21, which can increase the friction between the wiping portion 22 and the dispensing nozzle and improve the cleaning effect of the cleaning device on the dispensing nozzle.

[0046] In some embodiments, the wiping portion 22 comprises at least one of rubber, silicone, and sponge. That is, in some embodiments, the wiping portion 22 comprises rubber, in some embodiments, the wiping portion 22 comprises silicone, and in some embodiments, the wiping portion 22 comprises sponge. In some embodiments, the wiping portion 22 comprises both rubber and sponge, with the rubber and sponge being layered, and the sponge being in direct contact with the dispensing nozzle. This increases the diversity of structural solutions for the cleaning device.

[0047] like Figure 1 As shown, in some embodiments, the cleaning device further includes a detection member 60 , which is electrically connected to the driving unit 11 , and is used to detect the position of the dispensing nozzle.

[0048] According to the cleaning device of the embodiment of the present application, the detection part 60 is used to detect the position of the dispensing nozzle. When it is detected that the dispensing nozzle moves to the specified position, the detection part 60 is electrically connected to the driving part 11. The driving part 11 controls the movement of the wiping part 20 based on feedback, thereby wiping the dispensing nozzle, thereby achieving precise control of the cleaning device.

[0049] like Figure 2 and Figure 4 As shown, in some embodiments, the cleaning device further includes a first power assembly 50, which is transmission-connected to the driving assembly 10 to drive the driving assembly 10 to move along at least one direction of the X-axis, the Y-axis, and the Z-axis.

[0050] Specifically, the cleaning device also includes a first power component 50. When the cleaning device is used in a dispensing device, in order to adapt to the position of the dispensing nozzle and reduce the moving path of the dispensing nozzle, the first power component 50 is used to drive the driving component 10 and the wiping component 20 to move to the corresponding position, and then the driving component 10 drives the wiping component 20 to move to wipe the dispensing nozzle. The first power component 50 can synchronously drive the driving component 10 to move to avoid the dispensing component, thereby facilitating the dispensing nozzle to leave the wiping component 20 and move to the next workstation.

[0051] In some embodiments, the first power assembly 50 includes a first power unit, which is transmission-connected to the drive assembly 10 to drive the drive assembly 10 to move in one direction among the X-axis, Y-axis and Z-axis; further, the first power assembly 50 also includes a second power unit, which is transmission-connected to the first power unit, and the second power unit and the first power unit respectively drive the drive assembly 10 in two directions among the X-axis, Y-axis and Z-axis; further, the first power assembly 50 also includes a third power unit, and the third power unit, the second power unit and the first power unit are transmission-connected in sequence, and the third power unit, the second power unit and the first power unit respectively drive the drive assembly 10 to move in one direction among the X-axis, Y-axis and Z-axis.

[0052] In some specific embodiments, the first power unit, the second power unit, and the third power unit can all be a motor or a cylinder. For example, the first power unit is configured as a sliding module driven by a motor, the second power unit is configured as a sliding module driven by a motor, and the third power unit is configured as a sliding module driven by a motor.

[0053] like Figure 2 and Figure 4 As shown, in some embodiments, the cleaning device further includes a pneumatic indexing plate 40 , and the first power assembly 50 , the pneumatic indexing plate 40 and the drive assembly 10 are sequentially connected in transmission, and the pneumatic indexing plate 40 can drive the drive assembly 10 to rotate.

[0054] Specifically, the pneumatic indexing plate 40 can drive the drive assembly 10 to rotate. After the dispensing equipment is assembled, the pneumatic indexing plate 40 can be used to calibrate the positions of the drive assembly 10 and the wiper 20, ensuring that the wiper 20 is aligned with the dispensing nozzle during subsequent operations. Thus, the use of the pneumatic indexing plate 40 can simplify equipment commissioning, while also improving the adaptability of the cleaning device and increasing the diversity of its layout positions.

[0055] According to an embodiment of the present application, the dispensing equipment includes a dispensing nozzle, a second power assembly and the above-mentioned cleaning device. The second power assembly is transmission-connected to the dispensing nozzle to drive the dispensing nozzle to move.

[0056] The dispensing device according to the embodiments of the present application uses two wiping members 20 to jointly squeeze the dispensing nozzle. When the dispensing nozzle moves upward, the two wiping parts 22 generate frictional force on the dispensing nozzle, thereby achieving the effect of cleaning the dispensing nozzle. Since the wiping part 22 has elasticity, when the two wiping parts 22 are squeezed, the wiping part 22 will deform by extrusion to wrap the dispensing nozzle, so as to ensure that all positions of the dispensing nozzle along the circumferential direction can be cleaned in place. At the same time, there is no need to repeatedly rub and wipe the dispensing nozzle, which can prevent the dispensing nozzle from being damaged.

[0057] In some specific embodiments, the second power assembly includes at least one of a motor or a cylinder.

[0058] In some specific embodiments, the second power assembly includes a robotic arm, and the robotic arm drives the dispensing nozzle to move.
