Description

Technical Field

[0001] This utility model belongs to the field of PTC heating block production technology, specifically relating to a ceramic sheet feeding component for a PTC 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 consists of 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 by 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 the adhesive-coated surface is attached to the ceramic heating element 83. The assembly is then fed into a heating and pressurizing device to allow the adhesive to cure, resulting in the PTC heating block. This production method requires workers to place the ceramic heating elements 83 one by one on the upper surface of the adhesive-coated lower aluminum sheet 82, and then attach the adhesive-coated upper aluminum sheet 81 to the upper surface of the ceramic heating element 83. This individual placement method requires a large number of workers and demands a high level of skill; otherwise, it is difficult to effectively increase production capacity. Summary of the Invention

[0003] The purpose of this invention is to provide a ceramic sheet feeding component for a PTC heating block production device, which aims to replace manual labor in the existing PTC heating block production process by placing the ceramic heating elements, thereby reducing labor pressure and product production costs.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] A ceramic sheet feeding assembly for a PTC heating element production device includes a frame, a first vertical motion assembly, a first horizontal motion assembly, a conveying assembly, and a gripping assembly. The first horizontal motion assembly is fixed to the frame, and the first vertical motion assembly is fixed to the output end of the first horizontal motion assembly. The conveying assembly includes a conveyor belt, and multiple gripping assemblies are arranged side-by-side along the conveying direction of the conveyor belt at the output end of the first vertical motion assembly. The frame has a conveying channel along the conveying direction of the conveying assembly, and the conveying channel is located below the gripping assembly. Lower aluminum sheets are intermittently fed into the area below the gripping assembly through the conveying channel. The first horizontal motion assembly drives the gripping assembly to switch between above the conveyor belt and above the conveying channel, and the first vertical motion assembly drives the gripping assembly to move vertically up and down intermittently, so that the gripping assembly grips the ceramic heating element from the conveyor belt and transfers it to the lower aluminum sheet.

[0006] Based on the above solution and as a preferred embodiment of the above solution: it further includes a positioning component, which is fixed on the frame and includes a blocking plate. The blocking plate is located at a set position above the conveyor belt, and its lower end is close to the upper surface of the conveyor belt; the ceramic heating element on the conveyor belt is blocked by the blocking plate.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the first vertical motion component includes a cylinder and a mounting rod, the mounting rod is fixed on the piston rod of the cylinder, and the mounting rod is parallel to the conveying direction of the conveyor belt; the gripping component is detachably and fixedly mounted on the mounting rod.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: a through T-shaped groove is provided on the mounting rod along its axial direction; the gripping component includes a vacuum suction cup, a hollow connecting tube and a mounting base, the mounting base includes a T-shaped snap-fit ​​part that fits with the T-shaped groove with a clearance, the T-shaped snap-fit ​​part is embedded in the T-shaped groove, and a set screw passes through the T-shaped snap-fit ​​part and presses against the inner wall of the T-shaped groove.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the mounting base is provided with a mounting hole at the end away from the T-shaped snap-fit ​​part, the vacuum suction cup is fixedly installed at the lower end of the hollow connecting tube, and the hollow connecting tube is partially inserted and fixedly installed on the mounting hole.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: baffles are provided on both sides of the conveyor belt.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: a support plate is horizontally arranged below the conveyor belt, and the upper end surface of the support plate is in contact with the bottom surface of the conveyor belt.

[0012] The significant and beneficial technical effects of this invention compared to existing technologies are as follows: Workers place ceramic heating elements sequentially on a conveyor belt, which then transports them to below the gripping assembly. A first horizontal motion assembly moves the gripping assembly from above the conveyor channel to above the conveyor belt. When the gripping assembly is above the conveyor belt, a first vertical motion assembly moves it downwards to grip the ceramic heating elements on the conveyor belt, and then upwards. Driven by the first horizontal motion assembly, it moves to above the conveyor channel, where the first vertical motion assembly moves it downwards to release the ceramic heating elements, allowing them to be placed on the lower aluminum plate. Of course, through… The positioning components block the ceramic heating elements on the conveyor belt, ensuring they are arranged sequentially according to their placement order. By adjusting the positions of the gripping components, multiple gripping components simultaneously grab and place the corresponding number of ceramic heating elements onto the lower aluminum plate. In actual production, the working rhythm of the gripping components allows one worker to place ceramic heating elements onto the conveyor belts of at least two machines, thus replacing manual placement. This significantly reduces the number of workers and labor pressure, and improves production efficiency compared to workers aligning and placing each ceramic heating element onto the lower aluminum plate one by one.

[0021] See details Figure 1-5As shown, this application discloses a ceramic sheet feeding assembly for a PTC heating block production device, including 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, and multiple gripping assemblies 50 are arranged side by side on the first vertical motion assembly 20 along the conveying direction of the conveyor belt 43. On the output end; 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, and 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 assembly 20 includes a cylinder 21 and a mounting rod 24, the mounting rod 24 is fixed on the piston rod of the cylinder 21, and the mounting rod 24 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 assembly 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 assembly 32 is parallel to the first guide rail 34, and its lead screw 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 smoothness of the crossbar's movement. 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.

[0022] 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.

[0023] 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... This will cause the ceramic heating element at the front end to be restricted by the blocking plate 63 on the conveyor belt 43. 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 element arranged on the conveyor belt. Of course, it can also be adjusted adaptively according to the actual specifications of the ceramic heating element and the actual position required for gripping and placement.

[0024] 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.

[0025] 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.

[0026] 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.
