[0085] In order to make those skilled in the art better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0086] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0087] See also Figures 1 to 3The embodiment of the present invention provides an upper and lower air knife demoulding mechanism, comprising: an upper demoulding mechanism 10 and a lower demoulding mechanism 20, wherein the upper demoulding mechanism 10 comprises a demoulding device 101 and a demoulding plate 102. The lower demoulding mechanism 20 comprises a product fixture 201 and a support plate 202, wherein the product fixture 201 is mounted on the support plate 202, and an air blowing head 2021 is provided on the support plate 202, wherein the air blowing head 2021 is in communication with the product fixture 201, and the air is output to provide a demoulding force for the demoulded product on the product fixture 201 to move toward the upper demoulding mechanism 10; the demoulding plate 102 is used to adsorb the demoulded product under the action of the demoulding air pressure device, and drive the demoulded product to be demoulded under the control of the demoulding device 101.

[0088] Specifically, after the product is processed by injection molding or other methods, the product is attached to the product jig 201. Therefore, it is necessary to separate the product from the product jig 201 to realize the demoulding process. In order to separate the product that is tightly attached to the product jig 201. In addition to adsorbing the demoulded product through the demoulding plate 102 and pulling up the demoulded product under the action of the upward pulling force of the demoulding device 101, it is also necessary to provide an upward force to the bottom of the demoulded product through the blowing head 2021 and the bottom of the product jig 201. In this way, the demoulded product and the product jig 201 can be better separated by the up and down forces. The demoulded product that has been separated can be driven by the upper demoulding mechanism 10, and the demoulded product can be adsorbed by the support plate 202 and taken away from the product jig 201 to complete the demoulding process of the product. In the embodiment of the present invention, by adding a blow head 2021 joint under the product fixture 201, the blow head 2021 joint can be connected to the air source device, so that the gas can be output to the blow head 2021 through the air source device, and the gas can be output to the bottom of the product fixture 201 through the blow head 2021. The product fixture 201 is provided with a blow hole 2011, and the gas is output to the bottom of the demolded product through the blow hole 2011, thereby providing the demolded product with a demolding force to move in the direction of the upper demolding mechanism 10, and at the same time, combined with the upward pulling force of the demolding plate 102, the film-attached product can be better removed from the product fixture 201, while avoiding excessive pulling force of the demolding plate 102, which will damage the demolded product when pulling it. Among them, in one embodiment of the present invention, Figure 3 As shown in , the blowing head 2021 may be provided in plurality to provide a more uniform thrust to the demolded product. For example, four blowing heads 2021 may be provided, and the four blowing heads 2021 may be located near the four corners of the demolded product, thereby providing a more uniform thrust to the demolded product and better demolding the product.

[0089] See also Figure 3 and Figure 4 The lower demoulding mechanism 20 also includes a clamping device 203, and two of the clamping devices 203 are provided. The two clamping devices 203 are used to clamp and control the product fixture 201 during demoulding; the clamping device 203 includes: a mounting plate 2031, a clamping motor 2032, a slide rail assembly 2033 and a clamping block 2034. The mounting plate 2031 is provided with a mounting fixing column 2035, and the support plate 202 is fixedly connected to the mounting plate 2031 through the mounting fixing column 2035; the clamping motor 2032 is fixedly connected to the support plate 202; the slide rail assembly 2033 is installed on the mounting plate 2031; the clamping block 2034 is respectively connected to the clamping motor 2032 and the slide rail assembly 2033, so as to move along the slide rail assembly 2033 under the control of the clamping motor 2032.

[0090] Specifically, Figure 3 and Figure 4 As shown in , the product fixture 201 placed on the support plate 202 can be clamped and fixed by the clamping device 203 to better separate the product fixture 201 from the demoulded product. Figure 4 As shown in , the clamping motor 2032 can drive the clamping block 2034 to move, so that the clamping block 2034 can move along the extension direction of the slide rail assembly 2033. In this way, the two clamping blocks 2034 that move relative to each other can clamp or release the product fixture 201 placed on the support plate 202.

[0091] See also Figures 5 to 7 The stripping plate 102 is provided with one or more negative pressure suction heads 10222, and the negative pressure suction heads 10222 are interconnected with the air pressure device; the stripping plate 102 is also provided with an air outlet gap 102H1 at the edge of the demolding product on the product fixture 201 opposite to the edge of the demolding product, and the air outlet gap 102H1 is interconnected with the air pressure device to output gas to the surrounding of the demolding product on the product fixture 201 to provide a demolding force for the demolding product on the product fixture 201.

[0092] like Figure 5 and Figure 7 As shown in , the negative pressure suction head 10222 may be provided in plurality, and a more uniform suction force may be generated by the plurality of negative pressure suction heads 10222. In this way, when sucking the demoulded product, the demoulded product may be sucked more tightly, and the problem of being unable to pull the demoulded product away from the product fixture 201 due to insufficient suction force may be prevented.

[0093] In addition, if Figure 5 and Figure 6As shown in , by providing air outlet gaps 102H1 around the stripping plate 102, since the air outlet gaps 102H1 are interconnected with the air source device / air pressure device, gas can be output through the air outlet gaps 102H1 around the stripping plate 102, and the output gas forms an air knife, and when it acts on the gap around the demolded product and between the product fixture 201, the demolded product can be better separated from the product fixture 201. That is, in the embodiment of the present invention, the demolding operation is performed on the demolded product by the adsorption force of the negative pressure suction head 10222 and the action force of the upper and lower air knives, respectively, so that the product demolding operation can be better performed. During the demoulding process, air is first blown from the top to the surroundings of the demoulding product at a set angle through the air outlet gap 102H1. After blowing for 1 second, the air can be blown from the bottom of the demoulding product through the air blowing head 2021 for 1 second. Then, the demoulding product is sucked up by the demoulding plate 102, so that the demoulding product can be pulled away from the product fixture 201, and the demoulding product and the product fixture 201 are separated from each other. Figure 5 and Figure 6 In one embodiment of the present invention, the angle a between the air outlet slit 102H1 and the first direction is between 80 degrees; the width b of the cross section of the air outlet slit 102H1 is between 0.10 mm and 0.13 mm. In this way, a relatively sharp air knife can be formed to assist demoulding.

[0094] See also Figures 5 to 7 The stripping plate 102 includes: a stripping plate shell 1021 and a suction plate 1022. The stripping plate shell 1021 is provided with an air inlet connector 1024 and a negative pressure connector 1023. The air outlet gap 102H1 is interconnected with the air pressure device through the air inlet connector 1024; the negative pressure suction head 10222 is interconnected with the air pressure device through the negative pressure connector 1023; the suction plate 1022 is installed in the stripping plate shell 1021, and the air outlet gap 102H1 is formed between the suction plate 1022 and the stripping plate shell 1021.

[0095] like Figure 5 As shown in , the stripper template shell 1021 and the suction plate 1022 are fixedly connected. An air storage space 102H2 is formed between the stripper template shell 1021 and the suction plate 1022, and the air storage space 102H2 is interconnected with the air outlet gap 102H1. A plurality of air inlet connectors 1024 may be provided around the stripper template shell 1021, and each air inlet connector 1024 is interconnected with the air storage space 102H2. The gas introduced from the air inlet connector 1024 can be output from the air outlet gap 102H1, wherein the width of the cross section of the air storage space 102H2 is greater than the width of the cross section of the air outlet gap 102H1. As shown in Figure 5 As shown in FIG. 1 , the width of the cross section of the air storage space 102H2 is much larger than the width of the cross section of the air outlet slit 102H1 , thereby ensuring the air outlet stability of the air outlet slit 102H1 .

[0096] See also Figure 5 and Figure 7 One or more suction plate grooves 10221 are provided on the suction plate 1022, and one of the negative pressure suction heads 10222 is installed in one of the suction plate grooves 10221; each of the suction plate grooves 10221 is also provided with a negative pressure hole 10221H, and a sealing joint 10223 is also provided at the negative pressure hole 10221H, and the negative pressure hole 10221H is communicated with the negative pressure through hole of the negative pressure suction head 10222 through the sealing joint 10223; the sealing joint 10223 is used to seal the gap between the suction plate 1022 and the negative pressure suction head 10222.

[0097] like Figure 5 and Figure 7 As shown in , one or more negative pressure connectors 1023 may be provided on the demoulding plate housing 1021, and the negative pressure connectors 1023 may be interconnected with each negative pressure hole 10221H. In this way, each negative pressure hole 10221H may generate negative pressure, and the negative pressure may act on the demoulding product through the negative pressure suction head 10222 to adsorb the demoulding product. There may be multiple negative pressure suction heads 10222, so that a uniform adsorption force may be generated to adsorb the demoulding product. Since each of the negative pressure suction heads 10222 is installed in one of the suction plate grooves 10221, in order to seal the gap between the suction plate 1022 and the negative pressure suction head 10222, a sealing joint 10223 may be provided between the suction plate groove 10221 and the negative pressure suction head 10222, and a negative pressure hole 10221H is provided on the sealing joint 10223, and is connected to the negative pressure hole 10221H of the negative pressure suction head 10222.

[0098] See also Figure 2 , Figure 8 and Fig. 9The upper demoulding mechanism 10 also includes a material overweight detection device 103, and the demoulding device 101 is connected to the demoulding plate 102 through the material overweight detection device 103; the material overweight detection device 103 includes: a weight detection component 1031 and a material acquisition component 1032, the weight detection component 1031 is used to connect with the demoulding mechanism, and a tension sensor 10311 is provided on the weight detection component 1031; the material acquisition component 1032 is connected to the tension sensor 10311, and the tension sensor 10311 is used to detect the tension information of the grabbed material through the material acquisition component 1032, and when it is detected that the tension exceeds the set tension value, the demoulding mechanism is controlled to stop taking the material.

[0099] Specifically, Figure 8 and Fig. 9 As shown in , the tension sensor 10311 can detect the tension, so that the tension generated when pulling the demolded product can be detected, and it can be determined whether the tension exceeds the preset maximum tension value. The maximum tension value is usually set to a tension value that may be damaged by the demolded product. Due to the tight adsorption between the demolded product and the fixture or other abnormal conditions, it may cause the demolded product to be difficult to demold. When it is detected that the tension exceeds the maximum tension value, the demolding mechanism is controlled to stop taking materials, thereby avoiding the demolded product from being damaged. An alarm can also be issued to prompt timely processing by the staff.

[0100] See also Figure 8 and Fig. 9 The material acquisition group includes a demoulding connecting plate 10321, and the tension sensor 10311 is connected to the demoulding plate 102 through the demoulding connecting plate 10321; wherein the demoulding connecting plate 10321 can be fixedly connected to the demoulding plate 102 by screws. The weight detection component 1031 also includes: a slide rail mounting block 10312, and the slide rail mounting block 10312 is provided with a slide rail 10313, and the tension sensor 10311 is fixedly connected to the slide rail mounting block 10312, and the material acquisition group also includes a slider 10322, and the demoulding connecting plate 10321 can be slidably connected to the slide rail 10313 through the slider 10322. In this way, during the process of taking the mold and pulling up the demoulding plate 102, the slider 10322 can slide along the extension direction of the slide rail 10313. This allows the weight detection component 1031 and the material acquisition component 1032 to be floatingly connected. When the stripping plate 102 is demolded, a certain buffer force can be provided for the stripping plate 102 to avoid hard contact between the stripping plate 102 and the demolded product.

[0101] See also Figure 8 and Fig. 9The material acquisition group also includes a slider connecting plate 10323, and the slider 10322 is fixedly connected to the demoulding connecting plate 10321 through the slider connecting plate 10323; wherein, the slider connecting plate 10323, the slider 10322 and the slide rail 10313 are respectively provided with two, and the two slider connecting plates 10323, the slider 10322 and the slide rail 10313 are respectively arranged in parallel along the tension direction of the tension sensor 10311; through the slidable connection between the two sliders 10322 and the slide rail 10313, the tension between the weight detection component 1031 and the material acquisition component 1032 is more balanced.

[0102] The weight detection component 1031 further includes: a limit bar 10314, which is fixed on the slide rail mounting block 10312. The slider connecting plate 10323 is provided with a limit groove 103231 at the position corresponding to the limit bar 10314. The limit groove 103231 is used to conflict with the limit bar 10314 to limit the movement of the slider 10322. The limit bar 10314 can limit the slidable distance between the slider 10322 and the slide rail 10313, thereby limiting the maximum floating distance between the weight detection component 1031 and the material acquisition component 1032.

[0103] See also Figure 8 and Fig. 9 The weight detection component 1031 also includes: a sensor connection block 10315 and a flexible module 10316. The tension sensor 10311 is fixedly connected to the mounting block of the slider 10322 through the sensor connection block 10315. The installation of the tension sensor 10311 is facilitated by the sensor connection block 10315. The slide rail mounting block 10312 is connected to the demoulding mechanism through the flexible module 10316. In addition to the automatic centering of the workpiece insertion position error, the flexible module 10316 can also be used in the press-in process to keep the body and the cover plate in the center position, so as to achieve high-precision fine-tuning of the center position when taking materials.
