[0027] In order to make the purpose, method scheme and advantages of the embodiments of the present invention clearer, the method scheme in the embodiments of the present invention is clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] Example 1: Figures 1-5 As shown, a suction tip filter element pressing device includes: a plurality of adsorbents 1, a pressure plate 2 and an access control assembly, the side wall of the adsorbent 1 is provided with a limit block 11, the adsorbent 1 is used to absorb the filter element; the pressure plate 2 has free movement in the vertical direction, the pressure plate 2 is provided with a plurality of through holes 21, the adsorbent 1 is passed through the through holes 21, and the through holes 21 are provided with an arc groove 211 and a vertical groove 212 that are interconnected; when the adsorbent 1 is in the access state, the limit block 11 is located in the arc groove 211; the access control assembly, the access control assembly is transmission-connected to the adsorbent 1, and the access control assembly is used to drive one or more adsorbents 1 to rotate.

[0029] In the implementation process, the structure of the suction accessory 1 is a prior art, the suction accessory 1 is hollow inside, the bottom of the suction accessory 1 is provided with a suction hole, and the suction accessory 1 is connected with a vacuum device. When the vacuum device is started, negative pressure is generated inside the suction accessory 1, and then the filter element is adsorbed at the suction hole. When the filter element is pressed into the suction head, the vacuum device is turned off, and the suction accessory 1 is withdrawn from the suction head. Each suction accessory 1 can be connected with an independent branch pipe, and then all the branch pipes are connected with a main pipe, and the main pipe is connected with the vacuum device. Whether the suction accessory 1 corresponding to the branch pipe generates suction force is controlled by opening and closing the valve on the branch pipe.

[0030] In the embodiment, the center of the arc-shaped groove 211 can be on the central axis of the through hole 21. The arc-shaped groove 211 can also be directly provided as an annular groove. The suction accessory 1 in the taking state means that the suction accessory 1 is taking the filter element by suction force.

[0031] The operation of rotating the suction accessory 1 by the taking control assembly can make the limiting block 11 on the suction accessory 1 located in the arc-shaped groove 211 or the vertical groove 212. When the limiting block 11 is located in the arc-shaped groove 211, the pressing plate 2 moves up and down, and the suction accessory 1 moves up and down through the groove wall of the arc-shaped groove 211. When the limiting block 11 is located in the vertical groove 212, the pressing plate 2 moves up and down, the limiting block 11 slides in the vertical groove 212, and the suction accessory 1 does not move. Thus, during the operation, the number of suction accessories 1 taken can be controlled by controlling the number of limiting blocks 11 located in the arc-shaped groove 211. The control method is to rotate the suction accessory 1. As shown in Figure 5 The bottom end of the arc-shaped groove 211 communicates with the vertical groove 212, and when the limiting block 11 is turned to the bottom end of the vertical groove 212, the pressing plate 2 is pressed down, and the limiting block 11 slides in the vertical groove 212.

[0032] The suction head can be placed on the suction head placing plate as shown in Figure 10 , Figure 1 Only the structure schematic diagram when the device is provided with one row of suction accessories 1 is shown, the number of suction accessories 1 can be increased by rectangular arrangement, and then the pressing-in efficiency is improved.

[0033] In order to realize the control of the number of suction accessories 1 taken by one driving device, the embodiment is improved on the basis of the embodiment 1, as shown in Figures 6-8 The taking control assembly includes a gear 3 and a driving strip 4. The top end of the suction accessory 1 is connected with one gear 3. The driving strip 4 has a free movement degree in the horizontal direction, and one or more gear rack parts 41 are provided on the driving strip 4 to cooperate with the gear 3.

[0034] In the implementation process, the movement of the driving strip 4 can be realized by a telescopic rod or a telescopic cylinder. The movement of the driving strip 4 drives the gear 3 to rotate, and then drives the suction accessory 1 to rotate. The specific implementation mode has at least the following two modes:

[0035] Implementation method 1: Figure 8 As shown, a rack portion 41 is provided on the driving bar 4 ; the length of the rack portion 41 is smaller than the circumference of the gear 3 .

[0036] In the specific implementation process, when the device is in the initial state, the limit blocks 11 of all adsorption components 1 are located in the arc groove 211 or the vertical groove 212. At this time, the driving bar 4 can be as follows Figure 8 As shown, located on the far left or far right, after a rack portion 41 is provided at the end of the driving bar 4, the rack portion 41 is moved by a telescopic cylinder, and during the movement of the rack portion 41, it will engage with each gear 3 one by one for transmission. After the rack portion 41 completely passes through the gear 3, the rotation angle of the gear 3 causes the limit block 11 to switch between the arc groove 211 and the vertical groove 212. The number of gears 3 passed by the rack portion 41 is the number of adsorption parts 1 whose states are switched.

[0037] In order to prevent the rack portion 41 from meshing with two or even more gears 3 at the same time and reduce the required accuracy for regulation, further improvements can be made so that the spacing between adjacent gears 3 is greater than the length of the rack portion 41 .

[0038] During the specific implementation process, if the adjacent gears 3 are too close, the rack part 41 may engage with multiple gears 3 at the same time during the movement. At this time, it is more complicated to determine which adsorption parts 1 have completely switched, such as the determination of whether the limit block 11 moves from the arc groove 211 to the bottom of the vertical groove 212.

[0039] Implementation method 2: Figures 6-7 As shown, the driving bar 4 is provided with a plurality of rack portions 41 , each gear 3 corresponds to a rack portion 41 , and there is a gap between adjacent rack portions 41 ; the length of the gap gradually increases or decreases during the arrangement along the length direction of the driving bar 4 .

[0040] During the specific implementation process, Figure 6 and Figure 7 The middle gear 3 and the driving bar 4 are shown as being staggered up and down. They are set at the same level to achieve meshing transmission. Figure 6 As shown, the rack portion 41 is not in meshing state with the corresponding gear 3. During the horizontal movement of the driving bar 4, each rack portion 41 is meshed with the corresponding gear 3 in sequence. Figure 6 When the drive bar 4 in this state moves to the left, the leftmost rack portion 41 first meshes with the leftmost gear 3. At this time, the other gears 3 are not in meshing state. When the drive bar 4 continues to move to the left, the second rack portion 41 from the left meshes with its corresponding gear 3, and so on. After the rack portion 41 completely passes the corresponding gear 3, the rotation angle of the gear 3 realizes the switching of the suction element 1 to the use state.

[0041] The structure provided by the second embodiment can reduce the moving distance of the driving strip 4 when the same number of suction accessories 1 are taken, thereby reducing the length of the device and increasing the integration of the device.

[0042] In order to increase the stability of the pressing plate 2 during movement, the embodiment 3 is improved on the basis of the embodiments 1-2, as shown in the figure, the embodiment includes: a shell 5 and a telescopic mechanism 6, the pressing plate 2 is located in the shell 5 and is in sliding connection with the inner wall of the shell 5; the shell 5 is provided with an opening through which the suction accessory 1 passes; the output shaft of the telescopic mechanism 6 is connected with the pressing plate 2. Figures 1-3

[0043] In the specific implementation process, the shell 5 can be a cuboid as shown in the figure, and the telescopic mechanism 6 can be a telescopic air cylinder or a telescopic oil cylinder. The telescopic mechanism 6 is installed at the top of the shell 5, and an opening is formed at the top of the shell 5 for the output shaft of the telescopic mechanism 6 to pass through. After the output shaft passes through the opening, it is connected with the pressing plate 2. The sliding connection structure of the pressing plate 2 and the shell 5 is a prior art, which can be realized by providing two opposite vertical sliding rails on the inner wall of the shell 5 and then providing sliding blocks 52 on the side wall of the pressing plate 2 which cooperate with the sliding rails. It should be noted that, Figure 1 Figure 3 In the specific implementation process, the telescopic mechanism 6 is not shown in the figure.

[0044] In order to increase the stability of the driving strip 4 during movement, the embodiment 4 is improved on the basis of the embodiment 3, as shown in the figure, in the embodiment, the inner wall of the shell 5 is provided with a sliding groove 51, and the driving rack is provided with a sliding block 52 which cooperates with the sliding groove 51. Figure 9

[0045] In the specific implementation process, the sliding groove 51 can be horizontally arranged on the side wall of the shell 5. Under the cooperation of the sliding groove 51 and the sliding block 52, the horizontal movement of the driving strip 4 is more stable. If the suction accessories 1 are arranged in a rectangular shape, it is difficult to arrange the driving strip 4 corresponding to the middle suction accessory 1 on the side wall of the shell 5 due to the multiple suction accessories 1 arranged in the width direction of the shell 5. At this time, the sliding groove 51 can be arranged on the top wall of the shell 5. At this time, it should be noted that the position of the sliding groove 51 needs to avoid the output shaft of the telescopic mechanism 6.

[0046] In order to further reduce the size of the device, the embodiment 5 is improved on the basis of the embodiment 3, as shown in the figure, in the embodiment, the side wall of the suction accessory 1 is provided with a baffle 12, the inner wall of the shell 5 is connected with the bottom end of an elastic member 7, the top end of the elastic member 7 abuts against the bottom wall of the baffle 12, and the length of the vertical groove 212 is less than the maximum length of the moving path of the pressing plate 2. Figures 3-4

[0047] ​​​​In the implementation process, the elastic member 7 can be a spring, and the baffle 12 can be an annular plate coaxial with the suction member 1. Since the length of the filter core suction head has a wide range of specifications, the depth to which the filter core needs to be pressed can be relatively large. If the length of the vertical groove 212 is to completely adapt to the movement of the limiting block 11 in the vertical groove 212 during the pressing process of the pressing plate 2, the length of the vertical groove 212 is relatively large, and the thickness of the pressing plate 2 is relatively thick, thereby increasing the overall height of the shell 5. Therefore, the spring and the baffle 12 are arranged in the embodiment, so that even if the length of the vertical groove 212 is relatively short, the pressing plate 2 still has a certain pressable distance after the limiting block 11 reaches the top end of the vertical groove 212. In addition, the spring in the embodiment can provide a supporting force for the suction member 1 with the limiting block 11 located in the vertical groove 212, and will not hinder the lowering of the suction member 1 with the limiting block 11 located in the arc-shaped groove 211.

[0048] The preferred embodiments of the utility model are merely used for limiting the utility model, and the utility model can have various changes and variations for the person skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
