Description

Technical Field

[0001] This utility model belongs to the technical field of picking devices, and relates to an automatic picking device for molded products in a vacuum forming machine. Background Technology

[0002] A vacuum forming machine, also known as a thermoforming machine, is a machine that uses heated and plasticized rolls of thermoplastic materials such as PVC, PE, PP, PET, and HIPS to form various shapes of high-end packaging boxes, frames, and other products. After processing, because the products retain a certain temperature, a pick-up device is needed to remove them.

[0003] An automatic material handling device for an integrated injection molding and blow molding machine disclosed in Chinese Patent CN209454096U includes a machine base, a translation mechanism on the upper side of the machine base, a lifting mechanism on the upper side of the translation mechanism, a rotating mechanism on the upper side of the lifting mechanism, a flipping plate on the rotating mechanism, and a suction cup at one end of the flipping plate.

[0004] The current material handling device requires separate operation of a double-cylinder, a pneumatic cylinder, and a rotary cylinder to move, lift, and rotate the product, making operation cumbersome and increasing production costs. Whether the rotation can be automated while moving the product to reduce production costs has become a new research direction for those skilled in the art. Furthermore, during product transport, the product's temperature poses a risk of damaging other transfer and collection tools or accidentally burning workers.

[0005] To solve the above problems, this utility model proposes an automatic picking device for molded products from a vacuum forming machine. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes an automatic picking device for molded products from a vacuum forming machine.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a base plate, and a sliding plate is horizontally slidably provided on the top of the base plate via an electric telescopic rod. An airbag is fixedly connected between one side of the sliding plate and the end of the base plate.

[0008] A connecting frame is vertically slidably mounted directly above the skateboard. A rotating plate is rotatably mounted on the connecting frame. An electric suction cup is fixedly connected to the end of the rotating plate away from the skateboard. Several spray holes are opened on the rotating plate, and the spray holes are connected to the airbag.

[0009] A drive assembly is provided on the top of the base plate. When the electric telescopic rod drives the slide plate and the rotating plate to move horizontally on the top of the base plate, the drive assembly drives the rotating plate to rotate.

[0010] Furthermore, a groove is provided on the top of the base plate, and the bottom end of the slide plate is slidably connected to the inside of the groove;

[0011] The electric telescopic rod is fixedly connected to the top of the base plate, and the output end of the electric telescopic rod is fixedly connected to one side of the slide plate.

[0012] Furthermore, a fixing plate is fixedly connected to one end of the top of the base plate, and the end of the airbag away from the slide plate is fixedly connected to one side of the fixing plate.

[0013] Furthermore, the rotating plate has an air passage inside, one end of which is connected to several nozzles. The nozzles are arranged in a circumferential array about the electric suction cup. The other end of the air passage is fixedly connected to a hose, which passes through the slide plate and extends into the airbag.

[0014] Furthermore, hydraulic rods are fixedly connected to both ends of the bottom of the slide plate, and the output ends of the two hydraulic rods are fixedly connected to the bottom of the connecting frame.

[0015] Furthermore, a mounting groove is provided in the middle of the top surface of the connecting frame, and a rotating shaft is rotatably connected inside the mounting groove. One end of the rotating plate is fixedly sleeved on the rotating shaft.

[0016] Furthermore, the drive assembly includes two racks, which are symmetrically fixed to the top of the base plate, and both racks are located on the side of the slide groove;

[0017] Both ends of the rotating shaft rotatably pass through the connecting frame, and both ends of the rotating shaft are coaxially fixedly connected with gears. The gears correspond one-to-one with the racks, and the gears mesh with the corresponding racks.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The automatic picking device for vacuum forming machine products is equipped with a rack and pinion. The rack and pinion mesh with a gear. When the electric telescopic rod pushes the slide plate to move, the slide plate drives the connecting frame and the rotating plate to move. When the gear and the rack and pinion come into contact, the rack and pinion drive the gear to rotate, which in turn drives the rotating shaft and the rotating plate to rotate, thereby causing the electric suction cup and the vacuum forming machine product to rotate. This allows the vacuum forming machine product to be automatically driven to rotate while it is being moved, eliminating the need for separate drives, simplifying operation, and reducing production costs.

[0020] 2. The automatic product handling device of this vacuum forming machine is equipped with an airbag. The airbag is connected to several spray holes through a hose and air channel. When the electric telescopic rod pushes the slide plate to move, the slide plate will push one end of the airbag, causing the airbag to be compressed. The gas inside the airbag will be sprayed out through the spray holes, and then sprayed onto the vacuum forming product on the electric suction cup, thereby accelerating the cooling efficiency of the vacuum forming product and improving safety.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: an automatic picking device for molded products of a vacuum forming machine, including a base plate 1, and a sliding plate 3 is horizontally slidably arranged on the top of the base plate 1 via an electric telescopic rod 4.

[0027] The top of the base plate 1 has a groove 2, and the bottom end of the slide plate 3 is slidably connected to the inside of the groove 2. The groove 2 limits the sliding of the slide plate 3, thereby increasing the stability of the slide plate 3.

[0028] The electric telescopic rod 4 is fixedly connected to the top of the base plate 1, and the output end of the electric telescopic rod 4 is fixedly connected to one side of the slide plate 3. The slide plate 3 is moved by the electric telescopic rod 4.

[0029] An airbag 13 is fixedly connected between one side of the skateboard 3 and the end of the base plate 1. Moving the skateboard 3 will stretch or compress the airbag 13.

[0030] A fixing plate 14 is fixedly connected to one end of the top of the base plate 1, and the end of the airbag 13 away from the slide plate 3 is fixedly connected to one side of the fixing plate 14.

[0031] A connecting frame 15 is vertically slidably mounted directly above the slide plate 3. Hydraulic rods 5 are fixedly connected to both ends of the bottom of the slide plate 3, and the output ends of both hydraulic rods 5 are fixedly connected to the bottom of the connecting frame 15. The two hydraulic rods 5 work together to drive the connecting frame 15 to move vertically up and down.

[0032] A rotating plate 6 is rotatably mounted on the connecting frame 15.

[0033] A mounting groove 16 is provided in the middle of the top surface of the connecting frame 15. A rotating shaft is rotatably connected inside the mounting groove 16, and one end of the rotating plate 6 is fixedly sleeved on the rotating shaft. When the rotating plate 6 is in a horizontal state, one side of the rotating plate 6 contacts the bottom surface of the mounting groove 16, increasing the stability of the rotating plate 6.

[0034] An electric suction cup 8 is fixedly connected to the end of the rotating plate 6 away from the sliding plate 3. The electric suction cup 8 mainly works by controlling the airflow inside the electric suction cup 8 to create an air pressure difference, thereby adsorbing objects onto the suction cup surface. The electric suction cup 8 is an existing product.

[0035] The rotating plate 6 has several nozzles 10, which are connected to the airbag 13.

[0036] An air passage 11 is provided inside the rotating plate 6, with one end of the air passage 11 connected to several nozzles 10. A flexible hose 12 is fixedly connected to the other end of the air passage 11, passing through the slide plate 3 and extending into the airbag 13. This allows the rotating plate 6 to move the flexible hose 12 as it rotates. The nozzles 10 are arranged in a circumferential array around the electric suction cup 8, allowing gas to be sprayed onto the vacuum-formed product on the electric suction cup 8. This cools the vacuum-formed product, preventing it from overheating and causing significant deformation upon impact during subsequent processing. It also prevents accidental burns to workers or damage to other transport and collection tools caused by overheated vacuum-formed products, thus improving safety.

[0037] A drive assembly is provided on the top of the base plate 1. When the electric telescopic rod 4 drives the slide plate 3 and the rotating plate 6 to move horizontally on the top of the base plate 1, the drive assembly drives the rotating plate 6 to rotate.

[0038] The drive assembly includes two racks 9, which are symmetrically fixed to the top of the base plate 1. Both racks 9 are located on the side of the slide groove 2.

[0039] Both ends of the rotating shaft rotatably pass through the connecting frame 15. Gears 7 are coaxially and fixedly connected to both ends of the rotating shaft, with each gear 7 corresponding to a rack 9, and the gears 7 meshing with their corresponding racks 9. This allows the slide plate 3 to drive the gears 7 to move to the rack 9.

[0040] Working principle:

[0041] When in use, fix the base plate 1 to the discharge point of the vacuum forming machine. Start the electric telescopic rod 4, so that the output end of the electric telescopic rod 4 pulls the slide plate 3 to the side away from the fixed plate 14, driving the connecting frame 15 and the rotating plate 6 to move until the electric suction cup 8 is moved directly under the vacuum forming product.

[0042] At the same time, the slide plate 3 will pull one end of the airbag 13, causing the airbag 13 to extend. This allows gas to enter the interior of the airbag 13 through the nozzle 10, air passage 11, and hose 12.

[0043] Start hydraulic rod 5. The output end of hydraulic rod 5 pushes connecting frame 15 upward, causing rotating plate 6 and electric suction cup 8 to move upward until the top of electric suction cup 8 contacts the molded product. The molded product is then adsorbed by electric suction cup 8.

[0044] The electric telescopic rod 4 pushes the slide plate 3 and the rotating plate 6 to move closer to the fixed plate 14, so that the electric suction cup 8 and the vacuum forming product move together.

[0045] The slide plate 3 pushes one end of the airbag 13, compressing the airbag 13. The gas inside the airbag 13 is ejected through the hose 12, air passage 11, and nozzle 10, and the gas is sprayed onto the vacuum-formed product on the electric suction cup 8 to cool the vacuum-formed product.

[0046] When gear 7 moves to mesh with rack 9, rack 9 drives gear 7 to rotate. This causes the rotating shaft and rotating plate 6 to rotate, which in turn drives the electric suction cup 8 and the vacuum-formed product to rotate. When gear 7 disengages from rack 9, rotating plate 6 rotates exactly 180 degrees, causing the vacuum-formed product to face downwards.

[0047] The hydraulic rod 5 pulls down the electric suction cup 8, which releases the vacuum-formed product and allows it to fall into the receiving area, thus achieving automatic retrieval of the vacuum-formed product.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
