Technical Field

[0001] This utility model belongs to the technical field of PTC production equipment, specifically relating to a ceramic sheet feeding component for a PTC high-efficiency heating block production device. 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. This production method currently requires a large number of workers to effectively increase production capacity. However, this also leads to difficulties in recruiting workers, and with rising labor costs, this method undoubtedly increases the product's production cost, hindering its market competitiveness.

[0029] See details Figure 1-9 As shown, this application discloses a ceramic sheet feeding assembly for a PTC high-efficiency heating block production device, including a placement assembly, a feeding assembly, and a loading assembly. For details, see [link to details]. Figure 5-9As shown, the placement assembly includes a frame 10, a first vertical motion assembly 20, a first horizontal motion assembly 30, a conveying assembly 40, and a gripping assembly 50. The first horizontal motion assembly 30 is fixed on the frame 10, and the first vertical motion assembly 20 is fixed on the output end of the first horizontal motion assembly 30. The conveying assembly 40 includes a conveyor belt 43. Multiple gripping assemblies 50 are arranged side by side on the output end of the first vertical motion assembly 20 along the conveying direction of the conveyor belt 43. The frame 10 has a conveying channel 10a along the conveying direction of the conveying assembly 40. The conveying channel 10a is located below the gripping assembly 50, and the lower aluminum sheet is intermittently fed into the gripping assembly 50 through the conveying channel 10a. The first horizontal motion assembly 30 drives the gripping assembly 50 to switch between above the conveyor belt 43 and above the conveying channel 10a. The first vertical motion assembly 20 drives the gripping assembly 50 to move vertically up and down intermittently, so that the gripping assembly 50 grips the ceramic heating element from the conveyor belt 43 and transfers it to the lower aluminum sheet. Specifically, in this embodiment, the first vertical motion component 20 includes a cylinder 21 and a mounting rod 24. The mounting rod 24 is fixed to the piston rod of the cylinder 21 and is parallel to the conveying direction of the conveyor belt 43. The first horizontal motion component 30 includes a servo motor 31, a lead screw and nut pair 32, and a crossbar 33. The two ends of the crossbar 33 are slidably mounted on the frame 10 via parallel first guide rails 34 and second guide rails 35. The lead screw and nut pair 32 is parallel to the first guide rail 34, and its lead screw and nut 321 is fixedly connected to one end of the crossbar 33. The forward or reverse rotation of the servo motor 31 drives the crossbar 33 to move horizontally. Preferably, two parallel second guide rails 35 are arranged to improve the stability of the crossbar's operation. A mounting plate 331 is fixedly installed in the middle of the crossbar 33. The cylinder 21 is fixedly installed on the mounting plate 331, and a parallel vertical guide rail 22 is installed on the mounting plate 331. A lower mounting plate 23 is installed on the vertical guide rail 22. The lower mounting plate 23 is detachably fixedly connected to the piston rod of the cylinder 21. For example, the piston rod 211 of the cylinder 21 is threaded at its end. By opening a threaded hole on the end face of the lower mounting plate 23 facing the piston rod 211, the piston rod 211 is screwed into the threaded hole. Of course, to prevent the connection from loosening, a nut is provided on the piston rod 211. After the piston rod 211 is screwed into the threaded hole, the nut is turned to press it against the lower mounting plate 23 to achieve loosening. Of course, this structure can also adjust the height of the lower mounting plate 23, and after adjustment, the nut is tightened to fix it in place. The mounting rod 24 is fixedly installed on the lower mounting plate 23. Therefore, the height of the mounting rod 24 can be adjusted, which means that the height of the gripping assembly 50 can be adjusted.

[0030] The gripping component 50 is detachably and fixedly mounted on the mounting rod 24. Preferably, a through T-slot 241 is provided on the mounting rod 24 along its axial direction. The gripping component 50 includes a vacuum suction cup 51, a hollow connecting tube 52, and a mounting base 53. The mounting base 53 includes a T-shaped snap-fit ​​portion 531 that fits with the T-slot 241 with a clearance. The T-shaped snap-fit ​​portion 531 is embedded in the T-slot 241, and a set screw passes through the T-shaped snap-fit ​​portion 531 and presses against the inner wall of the T-slot 241. Furthermore, in order to facilitate the connection between the vacuum suction cup 51 and the vacuum generator, in this embodiment, a mounting hole 532 is preferably provided at the end of the mounting base 53 away from the T-shaped snap-fit ​​portion 531. The vacuum suction cup 51 is fixedly mounted on the lower end of the hollow connecting tube 52, and the hollow connecting tube 52 is partially inserted and fixedly mounted on the mounting hole 532. The upper end of the hollow connecting tube 52 is connected to the vacuum suction cup 51 through a pipeline.

[0031] It also includes a positioning component 60, which is fixed on the frame 10. The positioning component 60 includes a bracket 61 and a blocking plate 63. The blocking plate 63 is fixedly connected to the bracket 61 via a mounting plate 62. The bracket 61 is fixedly installed on the frame 10. The blocking plate 63 is located at a set position above the conveyor belt 43, with its lower end close to the upper surface of the conveyor belt 43. The ceramic heating element is conveyed by the conveyor belt 43. Since the ceramic heating element is conveyed through friction with the conveyor belt 43, when the ceramic heating element on the conveyor belt 43 is blocked by the blocking plate 63, the ceramic heating element... It will then slide against the conveyor belt 43, and the foremost ceramic heating element will be restricted on the conveyor belt 43 by the blocking plate 63. Then the ceramic heating elements on the conveyor belt will be arranged sequentially on the conveyor belt for the gripping component to grip. It should be noted that in this embodiment, the blocking plate 63 is preferably located near the last end of the gripping component 50. Its position needs to ensure that each gripping component 50 corresponds one-to-one with the ceramic heating elements arranged on the conveyor belt. Of course, it can also be adjusted adaptively according to the actual specifications of the ceramic heating elements and the actual position required for gripping and placement.

[0032] To prevent the ceramic heating element from being squeezed together after being blocked by the baffle plate 63, which could cause it to deviate and fall to the side of the conveyor belt, this embodiment preferably provides baffles 45 on both sides of the conveyor belt 43. The baffles 45 can be fixedly installed on the frame, for example, by laser cutting a stainless steel sheet of a certain thickness according to the actual required shape, and then fixing it to the frame with bolts.

[0033] Of course, since the ceramic heating element has a certain weight, when there are many ceramic heating elements on the conveyor belt 43, their gravity will cause the conveyor belt 43 to sag, and excessive deformation will make it difficult for the gripping component to grip the ceramic heating element accurately and stably. Therefore, in this embodiment, a support plate 44 is preferably horizontally arranged below the conveyor belt 43. The upper end surface of the support plate 44 contacts or maintains a small gap with the bottom surface of the conveyor belt 43, so as to support the bottom of the conveyor belt 43 when it sags without affecting the normal operation of the conveyor belt, thereby solving this problem.

[0034] See Figure 2-5 As shown, the feeding assembly includes a feeding box 130, in which ceramic heating elements are stacked. Specifically, in this embodiment, a support base 13 is provided on the frame 10 at the location of the feeding box 130. The support base 13 has an insertion channel for the feeding box 130, and the upper outer dimension of the feeding box 130 is larger than the insertion channel, so that after the feeding box 130 is inserted into the insertion channel, its outer edge limits and positions the feeding box 130 in the installation position. Therefore, the feeding box 130 is detachable. That is, after filling the feeding box 130 with enough ceramic heating elements and operating it for a period of time, the ceramic heating elements in the feeding box 130 will be exhausted, and the old feeding box 130 can be removed and replaced with a new feeding box 130 filled with enough ceramic heating elements.

[0035] 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.

[0036] In this embodiment, the second transfer assembly includes a second horizontal motion assembly 120, a second vertical motion assembly 110, and a second gripping assembly 70. The movement direction of the second horizontal motion assembly 120 is parallel to the movement direction of the first horizontal motion assembly 30. The second horizontal motion assembly 120 is fixed to the output end of the second vertical motion assembly 110, and the second gripping assembly 70 is fixed to the output end of the second horizontal motion assembly 120. The second gripping assembly 70 is located above the feed box 130, and the second horizontal motion assembly 120 drives the second gripping assembly 70 to switch between above the feed box 130 and the conveyor belt 43. When the second gripping assembly 70 is located above the feed box 130 and the conveyor belt 43, the second vertical motion assembly 110 drives the second gripping assembly 70 to move vertically downward, and then returns to the initial height. Preferably, both the second horizontal motion assembly 120 and the second vertical motion assembly 110 are cylinders, and the second horizontal motion assembly 120 is fixedly mounted on the output end of the second vertical motion assembly 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. At the same time, the vacuum device (vacuum generator) 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 downwards, causing the ceramic heating element to fall onto the conveyor belt. Then, the vacuum device (vacuum generator) 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.

[0037] 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.

[0038] 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.

[0039] Of course, in order to ensure reasonable feeding efficiency, this application preferably has two sets of symmetrical feeding components and feeding components, which can feed materials at the same time to meet the needs of the number of items 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 materials. This way, the feeding components can work continuously without stopping.

[0040] Therefore, the device of this application can automate the placement of ceramic heating elements onto the lower aluminum plate, thereby reducing the need for production workers, alleviating labor pressure, and effectively improving the efficiency of material feeding.

[0041] 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.
