[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] Embodiment: This embodiment provides an automatic feeding device for blister trays, see Figure 1 - Fig.14 Specifically, it includes a horizontal and vertical conveying mechanism, which includes a first bracket 1, and the left and right ends of the first bracket 1 are respectively rotatably installed with a first roller 101 and a second roller 102 arranged longitudinally, a transmission belt 103 is connected between the first roller 101 and the second roller 102, a first motor 104 is fixedly installed on the first bracket 1, and the driving shaft of the first motor 104 is connected to the first roller 101, the outer surface of the transmission belt 103 is provided with evenly distributed square grooves 2, and each square groove 2 is fixedly covered with an elastic rubber 201, a first annular groove 202 arranged around is provided in the transmission belt 103, and the first annular groove 202 is connected with a plurality of square grooves 2, and a plurality of circular grooves 2 are distributed around the cylindrical surface of the first roller 101 A first through hole 203 is arranged corresponding to the first annular groove 202, and the first through hole 203 is connected to the inside of the first roller 101. A plurality of second through holes 204 connected to the first annular groove 202 are distributed around the inner surface of the transmission belt 103, and the second through holes 204 are arranged corresponding to the first through holes 203. The outer side of the end of the second through hole 204 away from the first roller 101 is covered with a first cover plate 205, and the first cover plate 205 is installed in the first annular groove 202 through an elastic spring sheet. An air pump 3 is installed below the first bracket 1, and a vacuum generator 301 is installed on the first bracket 1, and the air inlet of the vacuum generator 301 is connected to the air outlet of the air pump 3. A flip conveying mechanism cooperating with the horizontal and vertical conveying mechanism is arranged on the outer side of the right end of the first bracket 1.

[0046] When the device is in use, the spare parts used in the production of new energy vehicles are placed in the corresponding blister trays, and the staff can use the device to transport the blister trays, thereby realizing automatic feeding operations on the blister trays and the new energy vehicle spare parts therein. When in use, the device can be installed on both sides of the new energy vehicle assembly production line, and automatically perform transportation operations to the corresponding assembly stations on both sides of the production line.

[0047] During use, the first motor 104 is powered on and started, driving the first roller 101 connected to its drive shaft to rotate, thereby driving the transmission belt 103 on the outside of the first roller 101 and the second roller 102 to rotate, and the blister tray carrying automotive parts is placed on the transmission belt 103 from the left side of the device, and transported to the right through the rotation of the transmission belt 103. During the transportation process, in order to avoid problems such as deflection, shaking, and displacement due to the soft texture of the blister tray, the air pump 3 installed under the first bracket 1 is powered on and started, and a high-speed airflow is filled into the vacuum generator 301. The airflow is ejected through the air outlet of the vacuum generator 301 and then enters the first roller 101. During the first roller 101 drives the transmission belt 103 to rotate, the first through hole 203 opened around the first roller 101 will be aligned with the second through hole 204 opened around the inner surface of the transmission belt 103. During the alignment process, the air in the first roller 101 The airflow passes through the first through hole 203 and the second through hole 204, pushes open the first cover plate 205, enters the first annular groove 202, and then enters each square groove 2 through the first annular groove 202. Under the filling of airflow, the elastic rubber 201 covering the numerous square grooves 2 expands and bulges outward. When the blister tray is placed on the top of the transmission belt 103, the edge position of the blister tray is stuck between adjacent elastic rubbers 201, and the elastic rubber 201 that expands and bulges outward due to the filling of airflow will fill and support the vacant space in the blister tray. The numerous elastic rubbers 201 that bulge outward after being inflated can not only limit the movement of the blister tray, but also form an adaptive stable support for the inside of the blister tray, which is beneficial to improving the stability of the blister tray when it is placed on the transmission belt 103 for transportation, and can effectively reduce the problems of deviation, collapse, shaking, etc. caused by the soft texture of the blister tray during automatic feeding, thereby improving the stability of the transportation production to a certain extent.

[0048] When the airflow in the first roller 101 passes through the first through hole 203 and the second through hole 204 that are connected, since the first cover plate 205 is installed in the first annular groove 202 through the elastic spring and covers the second through hole 204, the first cover plate 205 can form a one-way opening structure at the end of the second through hole 204 away from the first roller 101. When the first through hole 203 and the second through hole 204 are connected, the opening direction of the first cover plate 205 at the corresponding position is in the same direction as the airflow direction. The push of the airflow can overcome the support of the elastic spring, so that the airflow smoothly enters the first annular groove 202, while the first cover plates 205 at the remaining positions will be closed because the opening direction is opposite to the airflow direction, so that the airflow filled into the first annular groove 202 in the first roller 101 can finally be smoothly and stably filled into the square groove 2, driving the elastic rubber 201 to bulge outward adaptively, restricting and supporting the blister tray, which is conducive to ensuring the stability of the device during operation.

[0049] When the blister tray carrying auto parts is conveyed to the right by the conveyor belt 103, after the flipping conveying mechanism is started, the auto parts in the blister tray can be flipped and conveyed, so that the auto parts are separated from the blister tray, and the auto parts are grabbed and put into the assembly line for subsequent processing.

[0050] In the specific implementation process, Figure 7 - Fig.12 As shown, the outer surface of the elastic rubber 201 is provided with air holes 4, the transmission belt 103 is provided with a second annular groove 401 which is arranged around, and the second annular groove 401 is connected with many air holes 4, and the cylindrical surface of the second roller 102 is provided with many third through holes 402 which are arranged corresponding to the second annular groove 401, and the third through holes 402 are connected with the inside of the second roller 102, and the inner surface of the transmission belt 103 is provided with many fourth through holes 403 which are connected with the second annular groove 401, and the fourth through holes 403 are arranged corresponding to the third through holes 402, and the outer side of one end of the fourth through hole 403 close to the second roller 102 is covered with a second cover plate 404, and the second cover plate 404 is installed on the inner surface of the transmission belt 103 through an elastic spring sheet, and the inner diameter of the third through hole 402 is set to 1.2 times the outer diameter of the second cover plate 404.

[0051] When the device is used, in order to further improve the stability of the automatic feeding process of the blister tray, the negative pressure suction port on the vacuum generator 301 is connected to the inside of the second roller 102. In this state, a suction airflow can be formed in the second roller 102. When the second roller 102 drives the transmission belt 103 to rotate, the third through hole 402 formed around the second roller 102 will be aligned with the fourth through hole 403 formed around the inner surface of the transmission belt 103. During the alignment process, the airflow in the second roller 102 is sucked into the second annular groove 401 through the docking of the first through hole 203 and the second through hole 204. Then, through the connection between the air hole 4 and the second annular groove 401, the negative pressure adsorption effect formed by the air flow suction is formed at the air hole 4. Due to the filling of air flow, the elastic rubber 201 covered on the plurality of elastic rubbers 201 expands and bulges outward and fits with the inner end wall of the blister tray. This allows the adsorption connection formed by the air flow suction to act on the inner end wall of the blister tray through the air hole 4 opened on the outer surface of the elastic rubber 201. With the help of the negative pressure adsorption formed by the air flow suction, the blister tray can be firmly connected with the corresponding elastic rubber 201, which can further improve the stability and accuracy of the automatic feeding process of the blister tray.

[0052] During the above operation, since the second cover plate 404 is installed on the inner surface of the transmission belt 103 through the elastic spring sheet and covers the fourth through hole 403, the second cover plate 404 can form a one-way opening structure at the end of the fourth through hole 403 close to the second roller 102. When the third through hole 402 and the fourth through hole 403 are connected, the opening direction of the second cover plate 404 at the corresponding position is the same as the flow direction of the airflow. The driving force formed by the airflow suction can overcome the support of the elastic spring sheet, so that the airflow in the second annular groove 401 passes through the connected third through hole 402 and fourth through hole 403 and smoothly enters the second roller. 102, while the second cover plate 404 at the rest of the positions will be in a closed state because the opening direction is opposite to the air flow direction, so that stable airflow suction can be formed at each air hole 4, and the blister tray is stably and firmly connected. At the same time, by setting the inner diameter of the third through hole 402 to 1.2 times the outer diameter of the second cover plate 404, the outer diameter of the second cover plate 404 is smaller than the inner diameter of the third through hole 402. When the third through hole 402 and the fourth through hole 403 are connected, sufficient position space can be provided for the opening of the second cover plate 404. Under the cooperation with each other, the stability of the device during operation can be effectively improved.

[0053] In the specific implementation process, Figure 3 , Figure 6 , Figure 8 and Fig.10 - Fig.12 As shown, one end of the first roller 101 and the second roller 102 are both arranged as a through structure, and the first inner cylinder 206 and the second inner cylinder 405 are respectively slidably inserted in the first roller 101 and the second roller 102, and the first inner cylinder 206 and the second inner cylinder 405 are both fixedly connected to the first bracket 1, and a first through groove 207 corresponding to the first through hole 203 is provided on the side of the cylindrical surface of the first inner cylinder 206 away from the second inner cylinder 405, and a second through groove 406 corresponding to the third through hole 402 is provided on the side of the cylindrical surface of the second inner cylinder 405 away from the first inner cylinder 206, the interior of the first inner cylinder 206 is connected to the air outlet of the vacuum generator 301, and an electric control valve is connected between the interior of the second inner cylinder 405 and the negative pressure exhaust port of the vacuum generator 301.

[0054] When the device is used, the first inner cylinder 206 and the second inner cylinder 405 are inserted into the first roller 101 and the second roller 102 respectively. One end of the first roller 101 inserted into the first inner cylinder 206 and one end of the second roller 102 inserted into the second inner cylinder 405 are set as a through structure, and the other end is set as a closed structure, so that the first roller 101 cooperates with the first inner cylinder 206 to form a relatively closed space inside, and the second roller 102 cooperates with the second inner cylinder 405 to form a relatively closed space inside. During operation, the first roller 101 and the second roller 102 are connected to the first inner cylinder 206. The two rollers 102 rotate, and the first inner cylinder 206 and the second inner cylinder 405 remain in a fixed connection with the first bracket 1. This can not only ensure the stability of the first roller 101 and the second roller 102 rotating and driving the transmission belt 103 to rotate and transport, but also ensure the stable connection of the airflow in the first inner cylinder 206 and the second inner cylinder 405 in the first roller 101 and the second roller 102. The first through groove 207 is opened on the left side of the cylindrical surface of the first inner cylinder 206, and the right side of the cylindrical surface of the first inner cylinder 206 is in a closed state, which makes the first roller 101 rotate in the process In the embodiment, only the first through hole 203 on the left side of the cylindrical surface of the first roller 101 connected with the first through groove 207 can have airflow passing through, and the first through groove 207 on the right side of the cylindrical surface of the first roller 101 is in a closed state to prevent airflow from leaking through the first through groove 207 on the right side of the cylindrical surface of the first roller 101. Similarly, the second through groove 406 is opened on the right side of the cylindrical surface of the second inner cylinder 405, and the left side of the cylindrical surface of the second inner cylinder 405 is in a closed state, so that during the rotation of the second roller 102, only the first through hole 203 on the right side of the cylindrical surface of the second roller 102 connected with the second through groove 406 docked with the third through hole 402 for air to pass through, the second through groove 406 on the left side of the cylindrical surface of the second roller 102 is in a closed state, to prevent the airflow from leaking through the second through groove 406 on the left side of the cylindrical surface of the second roller 102. Under the cooperation with each other, the first roller 101 makes the airflow in the first annular groove 202 more concentrated, and the second roller 102 makes the airflow in the second annular groove 401 more concentrated, further improving the effect of supporting the inflation of the elastic rubber 201 during the operation of the device, and the effect of negative pressure suction at the air hole 4 for connection.

[0055] In the specific implementation process, Figure 1 and Fig.14As shown, a collecting box 5 is arranged below the right end of the first bracket 1, and a proximity sensor located below the transmission belt 103 is arranged at the right end of the first bracket 1. When the device is in use, the proximity sensor installed below the right end of the first bracket 1 can detect the approach of the blister tray on the transmission belt 103. When the staff uses the device to automatically feed the blister tray from left to right, when the blister tray carrying automobile parts moves to the right side of the transmission belt 103, the flip conveying mechanism arranged on the right side takes out the automobile parts in the blister tray, and the blister tray is continued to be conveyed to the right. Due to the connection formed by negative pressure adsorption at the air hole 4, when the flip conveying mechanism grabs the automobile parts, the blister tray will not move with the automobile parts under the action of electrostatic adsorption, contact friction, etc., and the blister tray can be separated from the automobile parts smoothly during the flip feeding process.

[0056] When the blister tray is transported to the bottom of the right end of the transmission belt 103, the blister tray will not fall down easily due to the adsorption connection formed by the air flow suction at the air hole 4. At this time, the proximity sensor can detect the blister tray moving to the bottom of the right end of the transmission belt 103, and transmits the detected relevant signal to the control device of the device. The control device controls the electric control valve between the inside of the second inner cylinder 405 and the negative pressure suction port of the vacuum generator 301 to be temporarily closed. The closing time can be set according to actual needs, generally 2s. When the electric control valve here is closed, the air flow suction at the air hole 4 is interrupted. In this state, the blister tray moved to the bottom of the right end of the transmission belt 103 can be smoothly dropped into the collection box 5 for collection, which is convenient for the staff to use it again later.

[0057] In the specific implementation process, Figure 1 , Fig.13 and Fig.14 As shown, the flipping and conveying mechanism includes a second bracket 6 arranged on the right side of the first bracket 1, and a swing frame 601 is rotatably installed at the top middle position of the second bracket 6 and is flipped to the left above the transmission belt 103. A second motor 602 is fixedly installed on the second bracket 6, and the driving shaft of the second motor 602 is transmission-connected to the rotating shaft of the swing frame 601. A moving platform 603 is installed on the swing frame 601, and a supporting plate 604 is fixedly installed on the bottom of the moving platform 603, and a plurality of suction cups 605 are fixedly installed on the bottom of the supporting plate 604, and an electric-controlled valve is connected between the suction cup 605 and the negative pressure suction port of the vacuum generator 301. The moving platform 603 is slidably installed in the swing frame 601, and transversely arranged electric slide rails are fixedly installed in the front and rear end walls of the swing frame 601, and the moving platform 603 is fixedly connected to the sliding end of the electric slide rail, and a support column 606 located on the right side of the swing frame 601 is fixedly installed on the second bracket 6.

[0058] When the device is in use, the staff uses the flipping conveying mechanism to cooperate with the horizontal and vertical conveying mechanisms on the left to complete the automatic feeding operation of the blister tray. The swing frame 601 is driven by the second motor 602 to flip to the left to the upper position of the right end of the transmission belt 103, and then the suction cup 605 is pressed on the auto parts in the blister tray. The negative pressure adsorption formed by the airflow suction in the suction cup 605 makes the auto parts and the suction cup 605 firmly connected. Then the second motor 602 drives the swing frame 601 to drive the auto parts to flip to the right, and finally the auto parts are located at the upper right position of the second bracket 6. During the flipping process, the long-distance transportation of the auto parts is completed, and the turning over of the auto parts is completed. It is suitable for conveying and loading in which the auto parts in the blister tray need to be turned over.

[0059] An upright support column 606 is installed on the right side of the second bracket 6, and the support column 606 can support the swing frame 601 that is flipped to the right, so that the swing frame 601 carrying the auto parts is in a horizontal and stable state after flipping to the right for transportation. The left side of the second bracket 6 is not provided with a structure to support the swing frame 601, so that the flip angle of the swing frame 601 to the left can be flexibly adjusted according to actual needs. By adjusting the flip angle of the swing frame 601 to the left, the suction cup 605 can absorb and grab auto parts of different thicknesses in the blister tray transported on the transmission belt 103. At the same time, when installing, the flip conveying mechanism can not only be set on the same straight line on the right side of the horizontal and vertical conveying mechanisms, but it can be adjusted at different angles relative to the right end of the transmission belt 103. It is only necessary to ensure that the suction cup 605 can be above the right end of the transmission belt 103 after the swing frame 601 is flipped to the left. By adjusting the installation position of the flip conveying mechanism, the feeding operation on the curved path can be realized, which is conducive to improving the flexibility of the device during actual use.

[0060] During the operation of the device, the position of the movable platform 603 in the swing frame 601 can be flexibly adjusted. During the flipping of the swing frame 601, the movable platform 603 can be driven to move by the electric slide rails installed in the front and rear end walls of the swing frame 601. This makes it convenient to flexibly adjust the position of the suction cup 605 to grab the automotive parts and the feeding position of the automotive parts after the swing frame 601 is flipped according to actual use requirements, which is conducive to further improving the flexibility of the device during operation.

[0061] In the specific implementation process, Figure 1 - Figure 2 , Figure 7 and Fig.14As shown, the right end of the first bracket 1 is fixedly mounted with a side plate 7 symmetrically arranged on the front and rear sides of the transmission belt 103, and a plurality of laterally distributed nozzles 701 are fixedly mounted on the side of the side plate 7 close to the transmission belt 103, and the nozzle 701 is located above the suction cup 605, and the nozzle 701 is connected to the air outlet of the vacuum generator 301. When the device is in use, a high-speed airflow is ejected from the plurality of nozzles 701. Since the nozzle 701 is arranged above the suction cup 605, the suction cup 605 grabs the auto parts in the blister tray and is driven by the swing frame 601 to flip to the right. Under the influence of relative movement, the auto parts will be swept from top to bottom by the airflow ejected from the plurality of nozzles 701 during the flipping process, and the auto parts are simultaneously cleaned by air blowing during the flipping and conveying process.

[0062] Specifically, the working principle and operation method of the present invention are as follows:

[0063] The staff places the blister tray loaded with auto parts on the transmission belt 103 from the left side, and then the first motor 104 is powered on and started, driving the first roller 101 to rotate, and then driving the transmission belt 103 to rotate, and the blister tray is transported to the right to perform automatic feeding operation. During the feeding process, the air pump 3 is started, and air flow is provided to the first inner cylinder 206 through the air outlet of the vacuum generator 301. When the first roller 101 drives the transmission belt 103 to rotate, the first through groove 207, the first through hole 203 and the second through hole 204 are connected and connected, and air flow is filled into the first inner cylinder 206. The first annular groove 202 is then entered into the square groove 2, driving the elastic rubber 201 to inflate and bulge outward, restricting the blister tray and supporting the blister tray from the inside. Synchronously, the negative pressure suction port of the vacuum generator 301 is used to provide air suction to the second inner cylinder 405. When the second roller 102 drives the transmission belt 103 to rotate, the second through groove 406, the third through hole 402 and the fourth through hole 403 are connected and connected. The suction airflow acts on the air hole 4 through the second annular groove 401, and the blister tray is adsorbed and connected to ensure the feeding stability.

[0064] When the blister tray is conveyed to the right end of the transmission belt 103, the second motor 602 drives the swing frame 601 to flip leftward onto the auto parts in the blister tray, and grabs the auto parts by suction of the airflow in the suction cup 605. Then the second motor 602 drives the swing frame 601 to drive the auto parts to flip rightward. During the flipping process, the airflow ejected from the nozzle 701 sweeps over the auto parts from top to bottom. During the conveying process, the auto parts are cleaned before installation, and the empty blister tray falls and is collected in the collection box 5.

[0065] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
