During the whole process, the operator only needs to manually insert the preform 20 into the corresponding positioning column 121, and one operator can complete the preform loading process, thereby saving labor and reducing labor costs; and since the preform 20 is placed into the entrance of the lower preform slide 10 with the help of the preform loading mechanism 200, compared with manual preform loading, the preform loading efficiency can be improved.

[0039] Preferably, the upper embryo component 220 includes a first robotic arm 221, a second robotic arm 222, a third robotic arm 223 and a connecting piece 224; the connecting piece 224 is rotatably arranged on the base 210 along the A direction, the first end of the first robotic arm 221 is rotatably arranged on the connecting piece 224 along the B direction, the first end of the second robotic arm 222 is rotatably arranged on the second end of the first robotic arm 221 along the B direction, the first end of the third robotic arm 223 is rotatably arranged on the second end of the second robotic arm 222 along the B direction, and the grasping component 230 is connected to the second end of the third robotic arm 223 and can rotate around the axis of the third robotic arm 223.

[0041] Preferably, the grabbing assembly 230 includes a grabbing power member 231 and two clamping plates 232. The grabbing power member 231 is movably arranged on the upper preform assembly 220. The two clamping plates 232 are both transmission-connected to the grabbing power member 231. The two clamping plates 232 are relatively parallel and spaced apart. The opposite sides of the two clamping plates 232 are both provided with clamping curved surfaces. The two clamping curved surfaces cooperate to form a clamping space capable of grabbing the bottle preform 20.

[0042] Specific combination Figures 1 to 3 As shown, the grabbing power member 231 drives the two clamping plates 232 to move closer to or away from each other, so as to realize the grabbing and placement of the preform 20. By setting the clamping curved surface on the sides of the two clamping plates 232 that are close to each other, during the grabbing process of the preform 20, the two clamping plates 232 are ensured to be more closely fitted to the outer wall of the preform 20, and the clamping effect is ensured while reducing the probability of causing grabbing damage to the clamped preform 20 during the grabbing process. In order to improve the connection convenience and connection strength of the two clamping plates 232, the two clamping plates 232 are respectively connected to the grabbing power member 231 through the corresponding connecting plates 233. The grabbing power member 231 is set with reference to the prior art and is not specifically limited here. In some other embodiments, in order to further reduce the probability of the clamped bottle being damaged, flexible parts such as silicone parts, rubber parts, cotton cloth, etc. are set on the corresponding clamping curved surface.

[0043] Preferably, both clamping plates 232 are configured as long strips, and multiple clamping curved surfaces are arranged at intervals on both clamping plates 232 along the extension direction of the clamping plates 232, and each two opposite clamping curved surfaces cooperate to form a clamping space. With such a configuration, the gripping assembly 230 can grip multiple preforms 20 in one gripping process, and the efficiency of preform loading can be further improved by completing the process of loading multiple preforms 20. In this embodiment, four clamping spaces are provided in the gripping assembly 230, and in other embodiments, the number of clamping spaces can be increased or decreased according to actual conditions, and the present invention is not limited thereto.

[0044] Preferably, the storage assembly 120 further includes a storage tray 122 movably disposed on the conveyor belt 110 , a plurality of positioning posts 121 are fixedly disposed on the storage tray 122 in an array, and one end of each positioning post 121 away from the storage tray 122 is disposed as a conical guide portion 1211 .

[0045] Combination Figure 1 and Figure 4 As shown, in order to further improve the convenience and efficiency of embryo loading, a plurality of positioning posts 121 are fixedly arranged on the storage tray 122 in a rectangular array, and the specification of the rectangular array is set corresponding to the number of clamping spaces in the gripping assembly 230. By setting the end of the positioning post 121 away from the storage tray 122 as a conical guide portion 1211, when the bottle mouth of the bottle preform 20 is inserted into the corresponding positioning post 121, the conical guide portion 1211 plays a role of guiding the insertion, so as to further improve the convenience of placing the bottle preform 20 in the storage assembly 120. In some other embodiments, it can also be set that the plurality of positioning posts 121 are fixedly arranged on the storage tray 122 in a circular array.

[0046] Furthermore, the storage assembly 120 further includes a plurality of buffer rings 123, which are sleeved on the plurality of positioning posts 121 in a one-to-one correspondence. In this way, when the mouth of the bottle preform 20 is inserted into the corresponding positioning post 121, the buffer ring 123 can reduce the collision between the mouth of the bottle preform 20 and the upper end surface of the storage tray 122, thereby reducing the bottle mouth of the bottle preform 20 from being damaged, so as to reduce the loss rate of the bottle preform 20 during the embryo loading process, thereby further reducing the cost. The buffer ring 123 can be set as a rubber ring, a silicone ring, a plastic foam ring, etc. according to actual needs. In some other embodiments, a flexible buffer pad can also be directly laid on the upper end surface of the storage tray 122.

[0047] Preferably, the feeding mechanism 100 also includes a conveying frame 130, on which two conveying channels are arranged in parallel, and conveyor belts 110 are arranged in both conveying channels, and the conveying directions of the two conveyor belts 110 are opposite; the conveying channel close to the embryo upper mechanism 200 is provided with a positioning and grasping area corresponding to the embryo upper mechanism 200, and a barrier 132 for limiting the storage component 120 to the positioning and grasping area is provided corresponding to the positioning and grasping area.

[0048] Specific combination Figure 1As shown, by setting two conveyor belts 110 with opposite conveying directions, when loading preforms, the conveyor belt 110 away from the preform loading mechanism 200 is used to place an empty storage component 120, so that the operator can insert the bottle preform 20 into the empty storage component 120, so as to prepare for the subsequent preform loading mechanism 200 to grab the bottle preform 20; then the storage component 120 with the bottle preform 20 inserted is transported to the positioning and grabbing area through the conveyor belt 110 close to the preform loading mechanism 200; and with the assistance of the barrier 132, the storage component 120 with the bottle preform 20 inserted is limited to the positioning and grabbing area, so that the grabbing component 230 can grab the bottle preform 20 on the storage component 120 to complete the preform loading process. The shape and installation position of the barrier 132 are set with reference to the prior art, and are not specifically limited here.

[0049] Preferably, at least one lifting and transplanting assembly (not shown in the figure) is provided on each of the two conveyor belts 110 , and the lifting and transplanting assembly can lift and transplant the storage assembly 120 from the current conveyor belt 110 to another conveyor belt 110 . With such arrangement, after the operator has inserted the preform 20 into the empty storage component 120, the lifting and transplanting component corresponding to the conveyor belt 110 away from the embryo loading mechanism 200 lifts and transplants the storage component 120 with the preform 20 inserted therein to the conveyor belt 110 close to the embryo loading mechanism 200, and then, with the operation of the conveyor belt 110, the storage component 120 with the preform 20 inserted therein is limited to the positioning and grabbing area to complete the embryo loading work, and at the same time, the operator inserts the preform 20 into the empty storage component 120 on the conveyor belt 110 away from the embryo loading mechanism 200; after the preform 20 on the storage component 120 in the positioning and grabbing area is completely grabbed, with the operation of the conveyor belt 110, the lifting and transplanting component corresponding to the conveyor belt 110 close to the embryo loading mechanism 200 lifts and transplants the empty storage component 120 to the conveyor belt 110 away from the embryo loading mechanism 200, so as to prepare for the next insertion of the preform 20. In this way, the embryo placement is realized in a circular path, so as to further improve the efficiency of embryo placement. The lifting and transplanting components are arranged with reference to the prior art, and will not be described in detail here.

[0050] Preferably, the embryo loading device also includes a first sensor (not shown in the figure) and a second sensor (not shown in the figure), both of which are communicatively connected to the embryo loading mechanism 200. The first sensor is arranged at the entrance of the embryo loading chute 10, and is used to sense whether there is a bottle embryo 20 at the entrance of the embryo loading chute 10. The second sensor is arranged in the positioning and grasping area, and is used to sense whether there is a storage component 120 in the positioning and grasping area.

[0051] During the embryo loading process, after the conveyor belt 110 transports the placement assembly 120 with the preform 20 inserted therein to the positioning and grasping area, the second sensor sends a grasping signal to the embryo loading mechanism 200, so that the embryo loading mechanism 200 can grasp the preform 20 in a timely and accurate manner; then the embryo loading mechanism 200 drives the preform 20 to the entrance of the embryo lowering slide 10. If the first sensor senses that there is no preform 20 at the entrance of the embryo lowering slide 10 at this time, the release signal is transmitted to the embryo loading mechanism 200, so that the grasping assembly 230 puts the grasped preform 20 into the entrance of the embryo lowering slide 10, so as to avoid the current preform 20 from colliding with the original preform 20 at the entrance of the embryo lowering slide 10. During the whole process, the first sensor and the second sensor cooperate with the embryo loading mechanism 200, so that the embryo loading mechanism 200 can timely and accurately grab the bottle embryo 20 placed in the positioning grabbing area, and put the grabbed bottle embryo 20 into the entrance of the embryo lowering slide 10, and can avoid the current bottle embryo 20 from interfering with other bottle embryos 20. In this way, automatic embryo loading is achieved while ensuring the embryo loading effect.

[0052] Furthermore, the positioning and grabbing area is provided with a limit column that can be raised and lowered, and the storage tray 122 is provided with a limit hole that allows the limit column to pass through, and the limit column is in communication connection with the second sensor. The second sensor can be set as a weight sensor. In order to further limit the relative position of the built-in component 120 in the positioning and grabbing area, when the storage component 120 with the bottle embryo 20 inserted is located in the positioning and grabbing area, the weight sensor senses the weight increase and transmits the rising signal to the limit column, and the limit column rises and is inserted into the limit hole to further limit the storage tray 122; when the loading is completed, the weight of the storage component 120 is reduced, and the weight sensor transmits the retraction signal to the limit column, and the limit column descends and retracts and disengages from the limit hole, so that the empty storage tray 122 is transported out of the positioning and grabbing area, and the next storage component 120 with the bottle embryo 20 inserted is transported into the positioning and grabbing area. The number of limiting columns can be adaptively set according to actual needs, and can meet the technical effect of further positioning the storage assembly 120 with the bottle embryo 20 inserted in the positioning and grasping area while avoiding interference with multiple positioning columns 121. The number and position of the limiting holes on the storage tray 122 are set corresponding to the limiting columns. The power piece that drives the limiting column to rise and fall can be set to a motor, a cylinder, etc. according to actual needs, and is not specifically limited here.
