Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram illustrating an inflation and charging mechanism 100 according to an embodiment of the present invention; FIG. 2 is a schematic illustration of the inflator mechanism 100 of FIG. 1 from another angle according to the present invention; an embodiment of the present invention provides an inflation and charging mechanism 100, where the inflation and charging mechanism 100 includes: an inflation and charging assembly 120. The inflation and charging assembly 120 includes a guide seat 123, an inflation and charging member 124, and a first driving member 122, wherein the number of the inflation and charging members 124 is at least two. The guide seats 123 are formed with first guide portions 1231, and the number of the first guide portions 1231 corresponds to the number of the inflatable members 124. Each inflation member 124 is correspondingly and correspondingly engaged with one first guiding portion 1231, and the first driving member 122 is used for driving the guiding seat 123 along the first direction S 1 So that the respective inflation members 124 are simultaneously moved in the guide direction of the first guide portions 1231. Wherein, along the first direction S 1 The intervals between the guide directions of the plurality of first guide portions 1231 tend to increase and remain equidistant.
For convenience of description, the evaporator and the condenser are collectively referred to as "two vessels" in the following.
The charging mechanism 100 is used for charging the evaporator and the condenser with nitrogen, for example, the first driving member 122 can drive the guide seat 123 to move relative to the charging member 124, so that the charging member 124 can move along the guiding direction of the first guiding portion 1231. Due to the fact that the first direction S is along 1 The intervals between the guide directions of the plurality of first guide portions 1231 tend to increase and be maintained at equal intervals, and thus the inflator 124 is directed to the guide base 123 in the first direction S 1 In the moving process, the distances among the guide pieces are kept to be equidistant to be increased or reduced, so that the distance between the air inflation and material filling pieces 124 is automatically adjusted, the filling operation of evaporators and condensers of different models is facilitated, the automatic filling efficiency is improved, the nitrogen filling automation and unmanned requirements of the evaporators and the condensers are met, and the production rhythm is improved.
It should be understood that the inflation and charging mechanism 100 described above can be used not only for nitrogen charging of both air conditioners, but also for automated processing of other products, such as batch welding, batch pick and release of workpieces, liquid charging, batch isometric processing, and the like.
For further understanding and explanation of the first direction S 1 Taking FIG. 1 as an example, the first direction S 1 Is a straight line S in FIG. 1 1 In the direction of any arrow, e.g. first direction S 1 The height direction when the guide base 123 is horizontally disposed.
It should be further noted that the first driving member 122 is used for driving the guide seat 123 along the first direction S 1 And moving to enable each inflation member 124 to synchronously move along the guiding direction of the first guiding portion 1231, wherein the relative movement mode is that the first driving member 122 drives the guiding seat 123 to move, the transmission action of the guiding seat 123 enables each inflation member 124 to equally diverge or converge along the guiding direction, the transmission mode may be a link transmission mode, a gear transmission mode, a belt transmission mode, a chain transmission mode or other transmission modes, and the guiding mode of the first guiding portion 1231 and the inflation member 124 may be a guide groove matching mode, a guide pillar matching mode or other guiding modes.
Alternatively, the first drive member 122 may be an electric motor, pneumatic cylinder, hydraulic cylinder, or other drive device.
Specifically, referring to fig. 1, the first driving member 122 is a cylinder. Therefore, the structure is simple, the reliability is high, and the guide seat 123 can move linearly conveniently. The present embodiment provides only one specific implementation of the first driving member 122, but not limited thereto.

Specifically, referring to fig. 1, the first guiding portion 1231 is a strip-shaped groove, and the length direction of the plurality of strip-shaped grooves is the guiding direction of the first guiding portion 1231. For example, there are five inflation members 124, five first guiding portions 1231, and five strip-shaped grooves are respectively disposed at an included angle. The length direction of the middle strip-shaped groove and the first direction S 1 The two parallel strip-shaped grooves are symmetrically arranged on two sides and form an angle with the strip-shaped groove in the middle, and the two strip-shaped grooves are four in total. So that the guide seat 123 is in the first direction S 1 The distance between the plurality of inflatable charging members 124 is equal when the inflatable charging members are lifted at any heightAnd the like. Thus, since the plurality of the nitrogen charging openings on the two air conditioners are arranged at equal intervals, the charging assembly 120 can meet the requirement of charging the plurality of the nitrogen charging openings of the two air conditioners, and can automatically change the distance between the charging members 124 aiming at the two air conditioners with different models, thereby improving the automatic nitrogen charging efficiency.

The charging tube 1243 is drivingly connected to the second driving member 1242, and the second driving member 1242 drives the charging tube 1243 along the first direction S 1 And (5) moving. Specifically, the second drive 1242 is a cylinder. In this way, when the guide base 123 moves, the driving base 1241 moves along the first guide portion 1231, so that the plurality of inflatable members 124 are scattered and gathered at equal distances.
Further, referring to fig. 1 and 2, the inflation mechanism 100 further includes a traverse assembly 110, the traverse assembly 110 includes a first guide 111, the inflation member 124 is guided to engage with the first guide 111, and the inflation member 124 can move along the second direction S on the first guide 111 2 Moving in a second direction S 2 And a first direction S 1 And (4) intersecting. In particular, the second direction S 2 And a first direction S 1 And is vertical. Thus, the inflatable members 124 can move along the first guide 111 in a guiding manner, when the guide base 123 moves up and down, the inflatable members 124 move under the guiding of the first guide 111 and the strip-shaped groove at equal intervals, the first guide 111 limits the downward movement of the inflatable members 124, and the lifting transmission of the guide base 123 is converted into the lifting transmission of the inflatable members 124 in the second direction S 2 And (c) upward.
Wherein the second direction S is described for further understanding and explanation 2 Taking FIG. 1 as an example, the second direction S 2 Is a straight line S in FIG. 1 2 In the direction indicated by any of the above arrows.
Alternatively, the first guide 111 may be a guide slot, a guide post, a guide rod, or other guide structure.

In one embodiment, referring to FIGS. 1 and 2, the traverse assembly 110 further includes a drive link 114. The transmission rod 114 is rotatably connected to the traverse seat 113, the second driving member 1242 is drivingly connected to the transmission rod 114, the mounting seat 121 is in driving fit with the transmission rod 114, and the second driving member 1242 drives the transmission rod 114 to rotate around its own axis to move the mounting seat 121. Specifically, the drive link 114 is a drive screw. The third driving member 112 is a servo motor. Thus, the mounting seat 121 and the transmission rod 114 are in threaded fit to form a screw transmission pair, and the rotation of the third driving member 112 is converted into the linear motion of the mounting seat 121, so as to drive the inflation charging assembly 120 to perform linear motion, and the pneumatic charging assembly is strong in stability and convenient to assemble.
