Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nozzle cleaning device, in particular to a stable clamping base. BACKGROUND

[0002] In the prior art, such as the patent application No. CN201480080738.1 patent document discloses a nozzle station setting device, please refer to the description of the drawings Figure 1 And Figure 2 It provides a nozzle transfer carrier - nozzle station NS, which is used for clamping a plurality of nozzles and can carry a plurality of nozzles in and out of the nozzle cleaning machine; and a support base is provided for fixing the nozzle station NS in the nozzle cleaning machine. After the nozzle station NS is fixed by the support base, it is driven by the moving mechanism to be transported into the cleaning chamber together with the support base, and the plurality of nozzles fixed in the nozzle station NS are cleaned. After the cleaning of the nozzle is completed, the moving mechanism drives the nozzle station NS and the support base to come out of the cleaning chamber, and the support base is operated to release the fixation of the nozzle station NS.

[0003] However, the support base provided by the technical scheme is "positioned and fixed on the intermediate base 62 in a detachable manner by the engagement fitting 71, the pressing fitting 72, the engagement block 75, the engagement pin 76, etc. The engagement fitting 71 and the pressing fitting 72 actually include a pressing piece and a screw structure, which cooperate with the intermediate base 62 to surround and clamp the base plate 31, and the screw is tightened to fix the nozzle station NS on the support base.

[0004] This screwing and disassembling method not only has a slow operation speed, but also has an impact and a high-frequency vibration when the cleaning machine cleans the nozzle, which can cause the screw thread connection between the screw and the intermediate base 62 to be "loose", resulting in the displacement of the nozzle station NS together with the cleaned nozzle, poor cleaning accuracy, and reduced cleaning cleanliness. Therefore, in the technical scheme, three switches S1-S3 sensors must be provided to detect whether the nozzle station NS1 is correctly seated on the intermediate base 62A, so that the displacement caused by the loosening of the screw can be adjusted in time.

[0005] Therefore, the support base for the nozzle station NS is not reasonable, and the cost of setting the sensor is high. CONTENT OF THE UTILITY MODEL

[0032] Please refer to Figure 3 Figure 7 The embodiment provides a stable clamping base, which comprises:

[0033] A support seat plate 1;

[0034] ​Linkage rotating shaft 2, which is arranged adjacent to one side surface of the support base plate 1 and rotationally connected with the support base plate 1; the outer wall of the linkage rotating shaft 2 is fixedly connected with a driving connecting rod 3 and a pressing connecting rod 4, and the driving connecting rod 3 and the pressing connecting rod 4 are arranged in a staggered manner; when the driving connecting rod 3 is driven by external force to drive the linkage rotating shaft 2 to rotate, the pressing connecting rod 4 rotates with the linkage rotating shaft 2; the suction nozzle intermediate transfer carrier (not shown) is provided with a pressure receiving portion (not shown) corresponding to the pressing connecting rod 4.

[0035] Limiting baffle 5, which is arranged on the opposite side of the linkage rotating shaft 2 and encloses a clamping area 6 corresponding to the suction nozzle intermediate transfer carrier with the pressing connecting rod 4.

[0036] Working principle: place the suction nozzle intermediate transfer carrier loaded with the to-be-cleaned suction nozzle into the clamping area 6; before placement, the driving connecting rod 3 can be driven by manual or automatic driving equipment to make the linkage rotating shaft 2 rotate, so that the pressing connecting rod 4 on the linkage rotating shaft 2 rotates away from the support base plate 1 to avoid obstacles, and the suction nozzle intermediate transfer carrier is placed into the clamping area 6 without obstruction.

[0037] Then, the driving connecting rod 3 is moved by the automatic driving equipment beside the support base plate 1, the pressing connecting rod 4 rotates with the linkage rotating shaft 2 until the set rotating limit of the linkage rotating shaft 2 is reached, and the pressing connecting rod 4 stably presses the pressure receiving portion; then one end of the suction nozzle intermediate transfer carrier is blocked by the pressing connecting rod 4 and pressed by the pressing connecting rod 4, and the other end of the suction nozzle intermediate transfer carrier is blocked by the limiting baffle 5 and stably fixed in the clamping area 6.

[0038] When the suction nozzle intermediate transfer carrier needs to be taken out of the clamping area 6, the driving connecting rod 3 is moved by the automatic driving equipment, the linkage rotating shaft 2 connected with the driving connecting rod 3 rotates, the driving connecting rod 3 is moved away from the pressure receiving portion, and the suction nozzle intermediate transfer carrier can be taken out of the clamping area 6 without obstacles.

[0039] Therefore, compared with the existing technology that uses screw tightening adjustment to fix the suction nozzle intermediate transfer carrier, the support base plate 1 has the advantages of being more convenient and fast, having high fixing stability, being easy to operate and saving time when disconnection, not needing to set a sensor to occupy space, and being lower in cost.

[0040] The driving connecting rod 3 is arranged opposite to the pressing connecting rod 4, which facilitates reasonable layout of the position of the automatic driving device, so that the linkage rotating shaft 2 is driven to rotate. In some embodiments, the automatic driving device can be a linear cylinder, a linear module or other prior art device capable of providing driving force to move the driving connecting rod 3. The limiting baffle 5 is located at the opposite side surface of the linkage rotating shaft 2 relative to the side surface of the support base plate 1. The limiting baffle 5 can be connected to the support base plate 1 as a whole, or can be located at a fixed position relative to the support base plate 1.

[0041] Please refer to Figure 4 and Figure 5 , the upper end of the limiting baffle 5 is provided with a bending plate 510 bent towards the direction of the linkage rotating shaft 2, and the suction nozzle intermediate transfer device is provided with a positioning groove (not shown) corresponding to the bending plate 510.

[0042] With the structure of the bending plate 510, compared with the straight plate structure of the limiting baffle 5, the resistance and positioning of the suction nozzle intermediate transfer device are more stable.

[0043] After the limiting baffle 5 is connected to the support base plate 1, it does not need to be repeatedly disassembled, and mainly needs to move the pressing connecting rod 4 to fix or release the suction nozzle intermediate transfer device.

[0044] Please refer to Figure 3 - Figure 5 , the upper end surface of the support base plate 1 is provided with a plurality of positioning columns 7, and the lower end surface of the suction nozzle intermediate transfer device is provided with a positioning groove (not shown) corresponding to the positioning columns 7; the end of the positioning column 7 is chamfered.

[0045] With this design, when the suction nozzle intermediate transfer device is placed into the clamping area 6, the positioning of the chamfered end of the positioning column 7 is facilitated, and the cleaning accuracy is improved.

[0046] Please refer to Figure 4 and Figure 5 , the support base plate 1 is provided with an avoidance groove 110 corresponding to the pressing connecting rod 4.

[0047] With this design, during the debugging stage, when the clamping area 6 of the support base plate 1 is not connected to the suction nozzle intermediate transfer device, the automatic driving device drives the linkage rotating shaft 2 to rotate excessively, and the pressing connecting rod 4 damages the support base plate 1.

[0048] Please refer to Figure 6 and Figure 7 , comprising a first ear plate group 8, the linkage rotating shaft 2 is connected to the support base plate 1 through the first ear plate group 8.

[0049] The linkage rotating shaft 2 is connected with the support base plate 1 through the first lug plate set 8, and is arranged adjacent to one side surface of the support base plate 1 with a distance, so as to facilitate the arrangement of the driving link 3 and the pressing link 4.

[0050] Please refer to Figure 6 and Figure 7 , which comprises the second lug plate set 9 and the third lug plate set 10, the driving link 3 is connected with the linkage rotating shaft 2 through the second lug plate set 9, and the pressing link 4 is connected with the linkage rotating shaft 2 through the third lug plate set 10.

[0051] Please refer to Figure 6 and Figure 7 , two first lug plates of the first lug plate set 8 are connected with two ends of the linkage rotating shaft 2 respectively, the second lug plate set 9 is arranged adjacent to the first lug plate set 8, the third lug plate set 10 is located between two second lug plates of the second lug plate set 9, the length directions of the linkage rotating shaft 2, the driving link 3 and the pressing link 4 are parallel, and a reinforcing rod 11 is connected between two third lug plates of the third lug plate set 10.

[0052] The reinforcing rod 11, the third lug plate set 10, the pressing link 4 and the linkage rotating shaft 2 form a "day" shaped structure, which is stable.

[0053] Preferably, an elastic member (not shown) is arranged, which is used to drive the driving link 3 and keep the pressing link 4 away from the support base plate 1.

[0054] In some embodiments, the elastic member is a torsion spring. In this way, after the automatic device cancels the driving of the driving link 3 to drive the linkage rotating shaft 2, so that the pressing link 4 presses the pressed part, the pressing link 4 is automatically kept away from the support base plate 1 under the elastic force of the torsion spring, the clamping area 6 is opened, and the suction nozzle intermediate transfer carrier is conveniently taken and placed.

[0055] Please refer to Figure 3 - Figure 5 , which comprises a driving device 12 and a push plate 13 arranged on the power output end of the driving device 12, and the driving device 12 is used to drive the push plate 13 to press the sliding cover plate (not shown) of the suction nozzle intermediate transfer carrier or to push the sliding cover plate to move.

[0056] Thanks to the improved structure, the space is sufficient to arrange the driving device 12 and the push plate 13 without the sensor, and through the driving device 12, the push plate 13 can be kept pressing the sliding cover plate of the suction nozzle intermediate transfer carrier during the cleaning process of the suction nozzle, so that the suction nozzle is tightly fixed to the suction nozzle intermediate transfer carrier and the position accuracy is maintained.

[0057] Please refer to Figure 3 and Figure 4The support base plate 1 is provided with a mounting groove 120, and the changeable baffle 14 is arranged in the mounting groove 120 and detachably connected with the support base plate 1.

[0058] With the increase of the use amount of the suction nozzle and the improvement of the suction nozzle cleaning machine, the suction nozzle cleaning machine can clean more suction nozzles at a time, however, there are also less suction nozzles to be cleaned, and the previous small amount of suction nozzles corresponding to the suction nozzle intermediate transfer carrier is directly eliminated, which is relatively wasteful. Therefore, in the case that the length of the support base plate 1 corresponds to clamping a large amount of suction nozzle intermediate transfer carriers, the changeable baffle 14 is used to make the support base plate 1 also correspond to clamping a small amount of suction nozzle intermediate transfer carriers.

[0059] In other words, the changeable baffle 14 plays a role of the limiting baffle 5, and holds and positions the end of the suction nozzle intermediate transfer carrier away from the linkage rotating shaft 2. The universality of the equipment is improved.

[0060] In the specification and claims of the present application, the words "comprise / comprising" and the words "have / having" and their conjugates, are used to specify the presence of stated features, numbers, steps or components, but do not exclude the presence or addition of one or more other features, numbers, steps, components or combinations thereof.

[0061] Some features of the present application are described in different embodiments for clarity, however, these features can also be combined in a single embodiment. Conversely, some features of the present application are described in a single embodiment for simplicity, however, these features can also be described in different embodiments alone or in any suitable combination.

[0062] The above is only the preferred embodiment of the present application, and does not limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
