Description

Technical Field

[0001] This utility model relates to the field of ceramic heating element production technology, and in particular to a plate changing device for PTC ceramic heating elements. Background Technology

[0002] PTC ceramic heating elements are heating elements made of ceramic materials based on the positive temperature coefficient (PTC) effect. Their core characteristic is that their resistance increases significantly with increasing temperature, thus enabling self-temperature control.

[0003] In the production process of PTC ceramic heating elements, after printing, the heating elements need to be baked in an oven. However, because a copper tray is used to support the heating elements during printing, the tray deforms after prolonged exposure to heat, rendering it unusable. Therefore, the copper tray must be replaced with a heat-resistant tray before baking. Currently, this tray-changing process typically relies on manual or semi-automated operation, requiring the heating elements to be removed or sucked out of the copper tray one by one and then transferred to the heat-resistant tray. This method is not only labor-intensive but also suffers from high labor costs and low work efficiency. Utility Model Content

[0035] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0036] See Figure 1 and Figure 2 This utility model provides a plate changing device for PTC ceramic heating elements, which includes: a multi-axis robot 100, a support 200, a suction cup assembly 300, a relative motion device 400, and a flipping mechanism 500.

[0037] The fixed end of the robotic arm 100 is mounted on a base 800.

[0038] The bracket 200 is installed on the movable end of the robotic arm 100.

[0039] The suction cup assembly 300 is fixed to the bottom of the bracket 200.

[0040] The relative motion device 400 is disposed below the support 200 and includes a first fixed seat 410 and a second fixed seat 420 that can move towards each other or away from each other.

[0041] The flipping mechanism 500 includes a first clamping rotating part 510 and a second clamping rotating part 520, which are arranged opposite to each other and are respectively fixed to the first fixed base 410 and the second fixed base 420. The first clamping rotating part 510 and the second clamping rotating part 520 are used to clamp the heat-resistant plate a and the copper plate b, which are closed together, from both sides during the plate changing process, and to flip the two plates by rotating them.

[0042] See Figure 1 The multi-axis robot 100 is typically a six-axis robot. This six-axis robot can achieve six degrees of freedom of movement, precisely adjust position and angle to ensure the efficiency and accuracy of the tray changing process, and can perform actions such as picking up and placing heat-resistant tray a, picking up and placing copper tray b, and moving the trays up and down. This six-axis robot is existing equipment, commonly used in automated production, and can be purchased directly from relevant manufacturers on the market.

[0043] In a preferred embodiment, see Figure 2 The suction cup assembly 300 includes a fixed plate 310 and a suction nozzle 320. The fixed plate 310 is fixed to the bracket 200, and the suction nozzle 320 is disposed on the fixed plate 310 for adsorbing the heat-resistant plate a or the copper plate b.

[0044] Furthermore, there are four suction nozzles 320, which are respectively disposed at the four corners of the fixed plate 310, for adsorbing the four corners of the heat-resistant plate a or the copper plate b. Each suction nozzle 320 is connected to an air pump through an air pipe. During operation, the air pump draws air, allowing the four suction nozzles 320 to adsorb the heat-resistant plate a or the copper plate b.

[0045] The suction cup assembly 300, in cooperation with the multi-axis robot arm 100, can perform the grasping and transfer actions of the heat-resistant plate a and the copper plate b.

[0046] In a preferred embodiment, see Figure 2 The relative motion device 400 includes a first cylinder 430 and a second cylinder 440 fixed below the bracket 200 and located on both sides of the suction cup assembly 300.

[0047] The first fixed seat 410 is fixed relative to the piston rod of the first cylinder 430 and is driven by it to perform linear motion. The second fixed seat 420 is fixed relative to the piston rod of the second cylinder 440 and is driven by it to perform linear motion.

[0048] Furthermore, the first cylinder 430 and the second cylinder 440 are installed back to back, that is, their piston rods are distributed in opposite directions.

[0049] Further, see Figure 2 The piston rod of the first cylinder 430 is connected to the top of the first fixed seat 410 through the first L-shaped connecting plate 450, and the piston rod of the second cylinder 440 is connected to the top of the second fixed seat 420 through the second L-shaped connecting plate 460.

[0050] In a preferred embodiment, see Figure 2 The first clamping and rotating part 510 includes a rotating pneumatic gripper 511, which is fixed to the bottom of the first fixing base 410 and is used to clamp one side of the disc body and flip the disc body by its own rotation.

[0051] The second clamping and rotating part 520 includes a rotary cylinder 521 and a pneumatic gripper 522 (a non-rotating pneumatic gripper). The rotary cylinder 521 is fixed to the bottom of the second fixed base 420, and its rotation axis is collinear with the rotation axis of the rotary gripper 511. The pneumatic gripper 522 is used to clamp the other side of the disc and is driven by the rotary cylinder 521 to rotate, thereby flipping the disc.

[0052] For more details, see Figure 2 The second clamping and rotating part 520 also includes a fixing plate 523, which is U-shaped and connected to the rotating shaft of the rotating cylinder 521. The pneumatic gripper 522 is installed in the U-shaped structure of the fixing plate 523.

[0053] Among them, the rotary gripper 511 and rotary cylinder 521 have a rotational degree of freedom of not less than 180°, which can realize the flipping action.

[0054] The flipping mechanism 500, through the coordinated action of the rotating gripper 511 and the rotating cylinder 521, can quickly and stably complete the flipping operation of the disc, ensuring the smooth replacement of the copper disc b and the heat-resistant disc a, and improving the disc replacement efficiency.

[0055] The aforementioned rotary pneumatic gripper 511, rotary cylinder 521, and pneumatic gripper 522 are all existing devices and can be purchased directly from relevant manufacturers on the market.

[0056] The following is a detailed description of the working process of this utility model.

[0057] Before starting work, the work scenario is as follows:

[0058] In the production process of PTC ceramic heating elements, after the PTC ceramic heating elements are printed, they need to be baked in an oven; before entering the oven, see... Figure 1 The PTC ceramic heating element is loaded on the copper plate b, which is conveyed by the conveyor belt 600 to move it to a designated position, where a lifting mechanism 700 is provided.

[0059] The plate changing device of this utility model is installed on the side of the conveyor belt 600. The side of the conveyor belt 600 is also divided into a first storage area 8a and a second storage area 8b. The first storage area 8a is used to store the heat-resistant plate a, and the second storage area 8b is used to store the copper plate b. The holes on the heat-resistant plate a and the copper plate b are in one-to-one correspondence.

[0060] During operation, the conveyor belt 600 transports the copper disc b carrying the PTC ceramic heating element to the designated position. Once the disc reaches the designated position, the conveyor belt 600 stops operating.

[0061] Subsequently, the lifting mechanism 700 was activated, raising the copper plate b to a certain height;

[0062] Simultaneously, the multi-axis robotic arm 100 operates, causing the suction cup assembly 300 to pick up a heat-resistant plate a from the first storage area 8a and move the heat-resistant plate a above the designated position; after the copper plate b is lifted, as... Figure 3 As shown, the movable end of the multi-axis robot 100 moves downward to cover the heat-resistant plate a on top of the copper plate b on the lifting mechanism 700; then, the suction nozzle 320 of the suction cup assembly 300 stops adsorbing the heat-resistant plate a.

[0063] Subsequently, the movable end of the multi-axis robotic arm 100 moves upward a certain distance, aligning the rotating gripper 511 and gripper 522 with the two closed discs. (See below) Figure 4 Then, the telescopic rods of the first cylinder 430 and the second cylinder 440 retract synchronously, allowing the claws of the rotating grippers 511 and 522 to engage with the edges of the two discs. The claws of the rotating grippers 511 and 522 then work to clamp the edges of the two discs tightly. (See below) Figure 5 and Figure 6 ;

[0064] Subsequently, the movable end of the multi-axis robotic arm 100 moves upward a certain distance, causing the two discs to be a certain height away from the lifting mechanism 700, in order to perform the flipping action. See [link / reference needed]. Figure 7 Subsequently, the rotary gripper 511 and the rotary cylinder 521 work to rotate the disc body 180°, causing the two disc bodies to flip over, so that the heat-resistant disc a is below and the copper disc b is above.

[0065] Subsequently, the movable end of the multi-axis robot 100 moves downward and places the two discs on the lifting mechanism 700;

[0066] Then, the grippers of rotary grippers 511 and 522 release, and the telescopic rods of the first cylinder 430 and the second cylinder 440 extend synchronously, allowing the grippers of rotary grippers 511 and 522 to move away from the edges of the two discs. See [link / reference]. Figure 8 ;

[0067] Subsequently, the movable end of the multi-axis robotic arm 100 moves downward a certain distance, allowing the suction nozzle 320 of the suction cup assembly 300 to touch the heat-resistant plate a; then, the air pump connected to the suction nozzle 320 operates, causing the suction nozzle 320 to adhere to the copper plate b. (See below) Figure 9 ;

[0068] Then, the movable end of the multi-axis robot 100 moves upward, causing the copper disk b to move away from the heat-resistant disk a. (See below) Figure 10 At this point, all the PTC ceramic heating elements originally mounted on copper plate b are transferred to heat-resistant plate a; then, the multi-axis robot 100 transfers the adsorbed copper plate b and places it in the second storage area 8b.

[0069] This completes one PTC ceramic heating element replacement operation; then, the lifting mechanism 700 descends to a position slightly below the conveyor belt 600, and repeats the previous operation to continue the subsequent PTC ceramic heating element replacement operation.

[0070] The top of the lifting mechanism 700 can be equipped with a corresponding clamping device (not shown in the figure) to clamp the plate when necessary, so as to prevent the plate from shaking and causing the PTC ceramic heating element to become misaligned.

[0071] In summary, this utility model, through the flexible operation of the multi-axis manipulator 100, the stable adsorption of the suction cup assembly 300, the position adjustment of the relative motion device 400, and the rotational flipping action of the flipping mechanism 500, can quickly complete the plate-changing operation of the PTC ceramic heating element from the copper plate b to the heat-resistant plate a, significantly improving production efficiency, reducing labor costs, and reducing labor intensity.

[0072] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
