Description

Technical Field

[0001] This utility model belongs to the technical field of PTC production equipment, specifically relating to a feeding device for the production of insulated heating blocks. Background Technology

[0002] PTC heating elements, also known as PTC heaters, consist of a PTC ceramic heating element and an aluminum tube. They offer advantages such as low thermal resistance and high heat exchange efficiency, making them an automatic temperature-controlled, energy-saving electric heater. A key feature is their safety performance; unlike electric heating tube heaters, they do not exhibit the surface "reddening" phenomenon under any application, thus avoiding burns, fires, and other safety hazards. Common PCT heating element structures include... Figure 1 As shown, it comprises an upper aluminum sheet 81, a lower aluminum sheet 82, and a ceramic heating element 83. The upper aluminum sheet 81 and the lower aluminum sheet 82 are fixedly bonded to the upper and lower end faces of the ceramic heating element 83 with conductive adhesive. Currently, the process for this type of PTC heating element involves placing a strip-shaped lower aluminum sheet 82 on a workbench, applying adhesive to the lower aluminum sheet 82, and then arranging ceramic heating elements of different specifications on the lower aluminum sheet 82 according to the designed sequence. Next, adhesive is applied to the lower surface of the upper aluminum sheet 81, and its adhesive-coated surface is adhered to the ceramic heating element 83. The assembly is then fed into a heating and pressurizing device, where the adhesive cures to obtain the PTC heating block. Currently, our company has developed an automatic placement device to replace manual placement of the ceramic heating elements, thus solving the problem of high labor pressure. However, this automatic feeding device requires a reliable feeding system to ensure stable material supply during the production process. Summary of the Invention

[0006] The feeding assembly includes a top feeding assembly and a second transfer assembly. The top feeding assembly is located below the second transfer assembly. The output end of the top feeding assembly enters the feeding box through the top feeding channel below the feeding box and contacts the ceramic heating element located at the bottom. The second transfer assembly grabs the ceramic heating element at the top of the feeding box and transfers it. Each time the second transfer assembly transfers the ceramic heating element, the output end of the top feeding assembly pushes it up a set distance.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the given embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0020] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0021] See details Figure 2-5 As shown, this application discloses a feeding device for producing insulated heating blocks, including a feeding box 30 and a feeding assembly. See [link to details]. Figure 2-5As shown, ceramic heating elements are stacked inside the feed box 130. Specifically, in this embodiment, a support base 13 is provided on the frame 10 at the location of the feed box 130. The support base 13 has an insertion channel for the feed box 130, and the upper outer dimension of the feed box 130 is larger than the insertion channel. This allows the feed box 130 to be positioned and aligned with the installation position after it is inserted into the insertion channel, with its outer edge limiting its movement. Therefore, the feed box 130 is detachable. That is, after sufficient ceramic heating elements are loaded into the feed box 130 and it operates for a period of time until the ceramic heating elements in the feed box 130 are exhausted, the old feed box 130 can be removed and replaced with a new feed box 130 filled with sufficient ceramic heating elements.

[0022] The feeding assembly includes a top feeding assembly 90 and a second transfer assembly. The top feeding assembly 90 is located below the second transfer assembly. The output end of the top feeding assembly 90 enters the feeding box 130 through the top feeding channel below the feeding box 130 and contacts the ceramic heating element located at the bottom. The second transfer assembly grabs the ceramic heating element at the top of the feeding box 130 and transfers it onto the conveyor belt 43. Each time the second transfer assembly transfers, the output end of the top feeding assembly 90 is pushed up a set distance. Specifically, the top feeding assembly 90 includes a top feeding drive 91, a top feeding plate 92, and a guide assembly 93. The top feeding drive 91 includes a servo motor and a lead screw and nut assembly. The nut of the lead screw and nut assembly is connected to the top feeding plate 92 through a connector. The servo motor rotates forward or backward, driving the top feeding plate 92 to move up a set distance intermittently according to a set rhythm, thus lifting the ceramic heating element located in the feeding box 130 upward. The guide assembly 93 includes symmetrically arranged guide rods and guide sleeves. The guide sleeves are fixedly installed on the frame, and the guide rods pass through the guide sleeves. One end of the guide rods is connected to the top plate 92, thereby providing stable guidance and support for the top plate 92, enabling the top plate 92 to operate smoothly and stably.

[0023] See Figure 3 and Figure 4As shown, in this embodiment, the second transfer component includes a second horizontal motion component 120, a second vertical motion component 110, and a second gripping component 70. The movement direction of the second horizontal motion component 120 is parallel to the movement direction of the first horizontal motion component 30. The second horizontal motion component 120 is fixed to the output end of the second vertical motion component 110, and the second gripping component 70 is fixed to the output end of the second horizontal motion component 120. The second gripping component 70 is located above the feed box 130, and the second horizontal motion component 120 drives the second gripping component 70 to switch between above the feed box 130 and the conveyor belt 43. When the second gripping component 70 is located above the feed box 130 and the conveyor belt 43 respectively, the second vertical motion component 110 drives the second gripping component 70 to move vertically downward, and then returns to the initial height. Preferably, both the second horizontal motion component 120 and the second vertical motion component 110 are cylinders, and the second horizontal motion component 120 is fixedly installed on the output end of the second vertical motion component 110 by a mounting plate or other support. A second mounting rod 140 is fixedly provided at the output end of the second horizontal motion component 120; the second gripping component 70 includes a plurality of vacuum suction cup components 71, and a second T-slot 143 is provided on the second mounting rod 140; it also includes a second mounting plate 72 corresponding to each vacuum suction cup component 71, each vacuum suction cup component 71 is fixedly mounted on one end of the corresponding second mounting plate 72, and the other end of the second mounting plate 72 is connected to the second mounting rod 140 through a T-nut assembly 144 installed in the second T-slot, thereby realizing that the vacuum suction cup component 71 can be detachably mounted on the second mounting rod 140. In the actual working process, initially, the vacuum suction cup assembly 71 is located directly above the feeding box 130 at a set height. The piston rod of the second vertical motion assembly 110 drives the second horizontal motion assembly 120 downward, causing the vacuum suction cup assembly 71 to contact the uppermost ceramic heating element on the feeding box 130. Simultaneously, the vacuum generator of the vacuum device activates, causing the vacuum suction cup assembly 71 to adsorb the ceramic heating element. Subsequently, the second vertical motion assembly 110 drives the second horizontal motion assembly 120 upward, picking up the ceramic heating element, and then the second horizontal motion assembly 120... The piston rod of the motion component 120 extends, driving the vacuum suction cup component 71 and the ceramic heating element to move upwards on the conveyor belt 43. After moving above the conveyor belt 43, the piston rod of the second vertical motion component drives the second horizontal motion component 120 to move downwards, causing the ceramic heating element to fall onto the conveyor belt. Then, the vacuum generator of the vacuum device cuts off the vacuum, and the ceramic heating element is released by the vacuum suction cup component 71 and falls onto the conveyor belt 43. This replaces manual placement of the ceramic heating element onto the conveyor belt, and in conjunction with the placement component, realizes automated downward aluminum sheet feeding.

[0024] Furthermore, in order to simplify the connection pipeline between the vacuum device and the vacuum suction cup assembly 71, this embodiment preferably provides a hollow channel 141 on the second mounting rod 140, which is connected to the vacuum device. Multiple vacuum connectors 142 connected to the hollow channel 141 are arranged side by side on the second mounting rod 140. Each vacuum connector 142 is connected to the corresponding vacuum suction cup assembly 71. Thus, the hollow channel 141 of the second mounting rod 140 is directly used to replace the traditional three-way or multi-way, simplifying the gas path structure.

[0025] Furthermore, since the vacuum suction cup assembly 71 obstructs the feed box 130 when it is in the working position, interference may occur during the replacement of the feed box 130, making it inconvenient to replace the feed box 130. To address this, this embodiment also includes a third horizontal motion assembly 100. The second transfer assembly is fixed to the output end of the third horizontal motion assembly 100, and the movement direction of the third horizontal motion assembly 100 is parallel to the movement direction of the second horizontal motion assembly 120. The third horizontal motion assembly 100 drives the second transfer assembly to switch between the standby position and the working position. When in the standby position, the feed box 130 is fully exposed to the outside for easy installation and removal of the feed box 130. Specifically, the second vertical motion component 120 is fixedly mounted on the connecting support plate 101. Preferably, the third horizontal motion component 100 is a cylinder, and the connecting support plate 101 is fixedly connected to the piston rod of the third horizontal motion component 100. Preferably, slide rails 14 are provided between the two ends of the connecting support plate 101 and the frame, so that the piston rod of the third horizontal motion component 100 extends and drives the second vertical motion component 120 to move towards the direction of the feeding box 130, so that the vacuum suction cup component 71 switches to the top of the feeding box 130 to perform the above-mentioned gripping action. When in standby mode or when the material needs to be changed, the piston rod of the third horizontal motion component 100 retracts, driving the second vertical motion component 110, the second horizontal motion component 120 and the second gripping component 70 to move to the standby position. At this time, the second gripping component 70 will be completely moved out from the top of the feeding box 130, fully exposing the feeding box 130 to the outside, so as to facilitate the replacement of the feeding box 130.

[0026] Of course, in order to ensure reasonable feeding efficiency, this application preferably has two sets of symmetrical feeding boxes and feeding components, which can feed simultaneously to meet the requirements of the number of ceramic heating elements to be placed. Alternatively, an alternating working method can be adopted, where the feeding box of one set needs to be replaced, and the other set is switched to feed. This way, the feeding component can be operated continuously without stopping.

[0027] Therefore, the device of this application realizes the feeding of materials to the automated placement device, which has a stable and reliable structure and low maintenance cost. The feeding device of this application realizes a stable and reliable feeding of materials to the placement device, so that the placement device can stably and reliably place the ceramic heating element on the lower aluminum plate, which reduces the demand for production workers, alleviates labor pressure, and can also effectively improve the efficiency of feeding.

[0028] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
