Description

Technical Field

[0001] This utility model relates to the field of ceramic heating element production technology, and in particular to a encoder robot 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, PTC ceramic heating elements need to be stacked one by one onto a copper plate (this process is called stacking plate) and then the printing process is carried out. Traditional stacking plate operation relies entirely on manual operation, which has the following disadvantages: (1) manual stacking is inefficient and labor-intensive; (2) labor costs are high, especially in batch production, multiple operators need to be configured; (3) manual operation is prone to fatigue, which can lead to stacking position deviation and affect printing accuracy.

[0004] Therefore, it is necessary to automate the disk stacking process by designing a robotic arm to address the shortcomings of current manual disk stacking operations. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a coding robot for PTC ceramic heating elements, so as to replace manual coding in coding operations and overcome the shortcomings of current manual coding operations.

[0008] A variable-pitch module is used to drive each of the adsorption modules to move by synchronously increasing or decreasing the spacing between them.

[0009] Before the adsorption module adsorbs the PTC ceramic heating element, the variable-pitch module first causes each adsorption module to synchronously reduce its spacing, so that each adsorption module corresponds one-to-one with multiple PTC ceramic heating elements linearly arranged in the first designated area; after the adsorption module adsorbs the PTC ceramic heating element from the first designated area, the variable-pitch module drives each adsorption module to synchronously increase its spacing, so that each adsorbed PTC ceramic heating element corresponds one-to-one with the slot on the copper disk in the second designated area.

[0020] The variable pitch module is connected to the bottom of the lifting mechanism, and the adsorption module is connected to the variable pitch module.

[0021] The first axis and the second axis are located at the two ends of the cantilever, and both are vertically extending axes.

[0022] Furthermore, the variable pitch module includes a motor, a module housing, and multiple sliders;

[0024] Each of the adsorption modules is fixedly connected to each of the sliders.

[0025] Furthermore, each of the adsorption modules is equipped with a suction nozzle for adsorbing PTC ceramic heating elements.

[0026] Furthermore, each of the adsorption modules is equipped with two suction nozzles, which are used to adsorb the two ends of the upper surface of the PTC ceramic heating element along its length.

[0039] 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.

[0040] See Figure 1 and Figure 2 This utility model provides a code disk robot for PTC ceramic heating elements, which includes an adsorption module 310, a lifting mechanism 320, a multi-axis motion module 330, and a variable pitch module 340.

[0041] The adsorption modules 310 are multiple and equally spaced along a linear direction, with each adsorption module 310 corresponding to adsorb one PTC ceramic heating element. Each adsorption module 310 includes a fixing block 312 and two suction nozzles 311. The fixing block 312 is mounted on the variable-pitch module 340, and the suction nozzles 311 are located at the bottom of the fixing block 312. The two suction nozzles 311 are used to adsorb the two ends of the upper surface of the PTC ceramic heating element along its length. Typically, the number of adsorption modules 310 is greater than or equal to two and less than or equal to eight. In the example shown in the figure, the number of adsorption modules 310 is four.

[0042] The variable-pitch module 340 is an existing device that can be used to achieve high-precision spacing adjustment and is widely used in fields such as automation equipment, precision machinery, and semiconductor manufacturing. In this invention, its function is to drive the various adsorption modules 310 to synchronously increase or decrease their spacing. The main structure of the variable-pitch module 340 includes a motor 341, a module housing 342, and multiple sliders 343. The motor 341 is mounted on the side of the module housing 342, and the sliders 343 are mounted on the bottom of the module housing 342, with each slider 343 arranged at equal intervals along a linear direction. When the motor 341 operates, it drives a worm gear (not shown in the figure) inside the module housing 342 to rotate. The rotation of the worm gear, in turn, drives the sliders 343 to move via a helical track on its surface, causing the sliders 343 to synchronously increase or decrease their spacing. The fixing blocks 312 of each adsorption module 310 are fixedly connected to each slider 343. Therefore, when the motor 341 is working, the movement of the slider 343 can drive the adsorption modules 310 to move synchronously to increase or decrease the spacing between them, thereby adjusting the spacing between the adsorption modules 310.

[0043] The lifting mechanism 320 is used to drive the variable pitch module 340 and the adsorption module 310 to move vertically, so that the adsorption module 310 can move down to approach the PTC ceramic heating element or move up after releasing the PTC ceramic heating element. The lifting mechanism 320 can be a worm gear lifting mechanism, which is a relatively common lifting mechanism and is therefore not specifically shown in the figure.

[0044] The multi-axis motion module 330 is used to drive the adsorption module 310 to move between above the first designated area 1a and above the second designated area 2a. The multi-axis motion module 330 includes a fixed frame 331, a first motion mechanism 332, a cantilever 333, a housing 334, and a second motion mechanism 335. The fixed frame 331 is used to fix the multi-axis motion module 330 in a predetermined position. The first motion mechanism 332 is installed inside the fixed frame 331. One end of the cantilever 333 is located at the top of the fixed frame 331 and is driven by the first motion mechanism 332 to rotate in the horizontal plane about the first axis 3a. The housing 334 is disposed at the end of the cantilever 333 away from the fixed frame 331 and is located above the cantilever 333. The second motion mechanism 335 is installed in the housing 334 and connected to the end of the cantilever 333 away from the fixed frame 331, and is used to drive the housing 334 to rotate in the horizontal plane about the second axis 3b. The lifting mechanism 320 is also installed in the housing 334 and is spaced a predetermined distance from the second motion mechanism 335. The variable pitch module 340 is connected to the bottom of the lifting mechanism 320, and the adsorption module 310 is connected to the variable pitch module 340. The first axis 3a and the second axis 3b are axes located at both ends of the cantilever 333, and both are vertically extending axes. The aforementioned multi-axis motion module 330 is an existing device widely used in automated production lines. The first motion mechanism 332 and the second motion mechanism 335 in this multi-axis motion module 330 can both be implemented using a structure where a motor drives a rotating shaft through a gear set (or pulley combination) (the specific structures of the first motion mechanism 332 and the second motion mechanism 335 are not shown in the figure).

[0045] Before the adsorption module 310 adsorbs the PTC ceramic heating element 800, the variable-pitch module 340 pre-emptively causes each adsorption module 310 to synchronously reduce its spacing, so that each adsorption module 310 corresponds one-to-one with the multiple PTC ceramic heating elements 800 linearly arranged in the first designated area 1a. After the adsorption module 310 adsorbs the PTC ceramic heating element 800 from the first designated area 1a, the variable-pitch module 340 drives each adsorption module 310 to synchronously increase its spacing, so that the adsorbed PTC ceramic heating element 800 matches the spacing of the slots 910 on the copper disk 900 in the second designated area 2a.

[0046] The purpose of setting up the variable pitch module 340 is that, since the PTC ceramic heating elements 800 are arranged in a linear array when they are stationary in the first designated area 1a, that is, each PTC ceramic heating element 800 is arranged one on top of the other (see...). Figure 4 When the PTC ceramic heating element 800 is transferred to the copper disk 900, there is a gap between the slots 910 of the copper disk 900 (see...). Figure 6Therefore, when adsorbing the PTC ceramic heating element 800, the adsorption modules 310 need to be close together to ensure that each adsorption module 310 can accurately adsorb the PTC ceramic heating element 800. After adsorption, the adsorption modules 310 need to be separated to match the spacing of the slots 910 on the copper disk 900, ensuring that the PTC ceramic heating element 800 can be accurately placed into the slots 910. For this purpose, the present invention specifically configures the aforementioned variable spacing module 340 to adjust the spacing of the adsorption modules 310 to match different needs during adsorption and placement.

[0047] The specific working process of the encoder robot of this utility model is as follows:

[0048] The multi-axis motion module 330 drives the adsorption module 310 to move above the first designated area 1a. Before the adsorption module 310 adsorbs the PTC ceramic heating element 800, the variable-pitch module 340 pre-emptively causes each adsorption module 310 to synchronously reduce its spacing, so that each adsorption module 310 corresponds one-to-one with the multiple PTC ceramic heating elements 800 linearly arranged in the first designated area 1a. Then, the lifting mechanism 320 operates, causing the adsorption module 310 to move downwards until the suction nozzle 311 is close to the PTC ceramic heating element 800. Immediately, the suction nozzle 311 draws air, adsorbing the PTC ceramic heating element 800. Afterwards, the lifting mechanism 320 operates in the opposite direction, causing the adsorption module 310 to move upwards. At the same time, the variable-pitch module 340... The adsorption modules 310 are driven to synchronously increase their spacing so that the spacing of the adsorbed PTC ceramic heating elements 800 is consistent with the spacing of the slots 910 on the upper surface of the copper disk 900. Then, the first motion mechanism 332 operates, and the second motion mechanism 335 works in conjunction, moving the adsorption module 310 directly above the copper disk 900 in the second designated area 2a. Afterwards, the lifting mechanism 320 operates, causing the adsorption module 310 to move downwards until each PTC ceramic heating element 800 is close to the corresponding slot 910 of the copper disk 900, at which point the suction nozzle 311... Stop the air intake and place each PTC ceramic heating element 800 into its corresponding slot 910; this completes one round of PTC ceramic heating element 800 stacking; then, the first motion mechanism 332, the second motion mechanism 335, and the lifting mechanism 320 drive the adsorption module 310 back above the first designated area 1a to begin the second round of PTC ceramic heating element 800 stacking; then, continue repeating until all PTC ceramic heating elements 800 have been stacked, or until all slots 910 on the copper disk 900 are filled with PTC ceramic heating elements 800.

[0049] The following are specific applications of the encoder robot of this utility model.

[0050] like Figure 3 and Figure 5As shown, an automatic encoder device for PTC ceramic heating elements is provided. The automatic encoder device includes a heating element conveyor belt 100, a copper disc conveyor belt 200, and an encoder robot 300 provided by this utility model.

[0051] The heating element conveyor belt 100 transports PTC ceramic heating elements 800 horizontally, with a predetermined first designated area 1a at a designated position. The PTC ceramic heating elements 800 stop linearly in the first designated area 1a on the heating element conveyor belt 100. Figure 4 .

[0052] The copper disk conveyor belt 200 transports the copper disk 900 horizontally, and a second designated area 2a is provided at a predetermined position. The second designated area 2a is a temporary stopping area for the copper disk 900 as it moves on the copper disk conveyor belt 200, see... Figure 6 .

[0053] The task of the encoder robot 300 is to grasp the PTC ceramic heating element 800 that is stationary in the first designated area 1a, and transfer it to the copper disk 900 that is stationary in the second designated area 2a. The encoder robot 300 grasps four PTC ceramic heating elements 800 at a time and transfers them into the pre-set slots 910 on the surface of the copper disk 900 that match the shape of the PTC ceramic heating elements 800.

[0054] Among them, such as Figure 4 As shown, the conveyor belt 100 for heating elements has a first belt body 150. The first belt body 150 is narrower, slightly wider than the PTC ceramic heating element 800, and has baffles 140 on both sides. During conveying, the length direction of the PTC ceramic heating element 800 is consistent with the extension direction of the first belt body 150. The width of the first belt body 150 restricts the PTC ceramic heating elements 800 to a single-row arrangement, preventing them from being arranged side-by-side. Typically, as... Figure 4 As shown, the heating element conveyor belt 100 may include two or more first belt bodies 150 arranged in parallel to improve transmission efficiency.

[0055] Among them, such as Figure 6As shown, the copper disc conveyor belt 200 includes two parallel second belt bodies 220, with the copper disc 900 spanning across the two second belt bodies 220. Furthermore, the slot 910 of the copper disc 900 on the copper disc conveyor belt 200 has the same orientation angle as the PTC ceramic heating element 800 on the heating element conveyor belt 100, meaning their length and width are consistent. This consistency allows the robotic arm 300 to transfer the PTC ceramic heating element 800 without angle adjustment. It only needs to grab the element from the first designated area 1a, move it along a reasonable path to the copper disc 900 in the second designated area 2a, and then release it. During this process, there is no need to adjust the angle of the PTC ceramic heating element 800 due to the different orientation angles of the slot 910 and the PTC ceramic heating element 800.

[0056] Usually, such as Figure 3 As shown, the first designated area 1a is equipped with a first positioning device 110, which is used to restrict the moving endpoint of the PTC ceramic heating element 800, forcing it to stay in a linear queue in the first designated area 1a.

[0057] Specifically, such as Figure 4 As shown, the first positioning device 110 is disposed at the front end of the first designated area 1a and fixed to the frame of the heating element conveyor belt 100. The bottom of the first positioning device 110 is provided with a protruding portion 111, which extends from top to bottom to be close to the upper surface of the heating element conveyor belt 100. It forms a barrier by contacting the PTC ceramic heating element 800 located at the front end, so that a number of PTC ceramic heating elements 800 are linearly arranged and stationed in the first designated area 1a.

[0058] See Figure 4 It should be noted that the lower surface of the protrusion 111 needs to be lower than the upper surface of the PTC ceramic heating element 800, and at the same time, it should maintain a gap with the first belt body 150 of the heating element conveyor belt 100 to ensure that the protrusion 111 can both block the PTC ceramic heating element 800 and not compress the first belt body 150 below, so as to avoid affecting its normal operation.

[0059] Further, see Figure 4 The first designated area 1a is also equipped with a pressure plate 120 and a third cylinder 130. The pressure plate 120 is located at the rear end of the first designated area 1a, and a protruding pressure block 121 is provided at its bottom. The third cylinder 130 is fixed to the frame of the heating element conveyor belt 100, and its piston rod is connected to the pressure plate 120 to drive the pressure plate 120 to move vertically, so that the protruding pressure block 121 presses or releases the PTC ceramic heating element 800 below.

[0060] Figure 4As shown, the distance between the pressure plate 120 and the first positioning device 110 is slightly greater than the sum of the lengths of the four PTC ceramic heating elements 800, allowing four PTC ceramic heating elements 800 on a single first belt 150 to be arranged in the first designated area 1a. The encoder robot 300 can simultaneously grasp these four PTC ceramic heating elements 800 each time.

[0061] In this design, the number of protrusions 111 in the first positioning device 110 matches the number of first belt bodies 150, and the number of protruding pressure blocks 121 in the pressure plate 120 also matches the number of first belt bodies 150. That is, if there are two first belt bodies 150, then the number of protrusions 111 and protruding pressure blocks 121 is also two, and they correspond to the two first belt bodies 150 respectively.

[0062] During operation, when the encoder robot 300 grasps the PTC ceramic heating element 800 that is stationary in the first designated area 1a, the third cylinder 130 will drive the pressure plate 120 to move downward in advance, so that the protruding pressure block 121 presses the PTC ceramic heating element 800 below (i.e., the fifth PTC ceramic heating element 800 from the front in the figure) firmly, so as to avoid the adjacent fifth PTC ceramic heating element 800 being moved and misaligned when the encoder robot 300 grasps the first four PTC ceramic heating elements 800.

[0063] Usually, such as Figure 5 and Figure 6 As shown, the second designated area 2a is equipped with a second positioning device 210, which is used to clamp and stably hold the copper disk 900 in the second designated area 2a.

[0064] Specifically, such as Figure 7 As shown, the second positioning device 210 includes two clamping blocks 211, a first cylinder 212, and a second cylinder 213. The two clamping blocks 211 are located between the two second belt bodies 220 of the copper disc conveyor belt 200 and are arranged at intervals facing each other along the conveying direction of the copper disc conveyor belt 200. The first cylinder 212 is a double piston rod cylinder, which is disposed between the two clamping blocks 211. Its two piston rods are respectively connected to the two clamping blocks 211 and are used to drive the two clamping blocks 211 to move towards or away from each other, so as to clamp or release the copper disc 900 that is stationary in the second designated area 2a. The piston rod of the second cylinder 213 is connected to the first cylinder 212 and is used to drive the first cylinder 212 to perform vertical lifting and lowering movements, so that the clamping blocks 211 are lower or higher than the copper disc 900 that is stationary in the second designated area 2a.

[0065] Furthermore, such as Figure 7As shown, the bottom of the first cylinder 212 is fixed to a mounting base 214. The second cylinder 213 is located below the first cylinder 212 and is fixed to a corresponding mounting bracket 215. The piston rod of the second cylinder 213 extends vertically and is connected to the bottom of the mounting base 214, which is used to drive the mounting base 214 to perform vertical lifting and lowering movements.

[0066] During operation, when the copper disc conveyor belt 200 transports the copper disc 900 between the two clamping blocks 211, the copper disc conveyor belt 200 pauses its operation. Then, the second cylinder 213 operates, pushing the mounting base 214 upwards, so that the two clamping blocks 211 are positioned on either side of the copper disc 900. Afterwards, the first cylinder 212 operates, causing the two clamping blocks 211 to move towards each other, firmly clamping the copper disc 900. Subsequently, the stacking robot arm 300 can grasp the disc that is stationary in the first designated area 1. The PTC ceramic heating element 800 is then transferred to the slot 910 of the copper disk 900. After all the slots 910 on the copper disk 900 are filled with PTC ceramic heating elements 800, the first cylinder 212 reverses its operation, causing the two clamping blocks 211 to move in opposite directions and release the copper disk 900. Then, the second cylinder 213 reverses its operation, causing the two clamping blocks 211 to descend. After that, the copper disk conveyor belt 200 starts running, transporting the copper disk 900 to the subsequent process.

[0067] The working principle of the above-mentioned automatic encoder is as follows:

[0068] During operation, the heating element conveyor belt 100 successively transports multiple PTC ceramic heating elements 800 horizontally towards the first designated area 1a. Under the obstruction of the first positioning mechanism 110, the multiple PTC ceramic heating elements 800 are linearly lined up and remain in the first designated area 1a. At the same time, the copper disk conveyor belt 200 successively transports multiple copper disks 900 horizontally towards the second designated area 2a. When the foremost copper disk 900 moves to the second designated area 2a, the copper disk conveyor belt 200 stops running, and then the second positioning device 210 works to clamp the copper disk 900 securely (the working process of the second positioning device 210 clamping the copper disk 900 has been described above).

[0069] Afterwards, the encoder robot 300 works by first grabbing four PTC ceramic heating elements 800 from the first designated area 1a, then transferring them to the second designated area 2a, and releasing the grabbed PTC ceramic heating elements 800 into the slots 910 of the copper disk 900 (the process of the encoder robot 300 transferring the PTC ceramic heating elements 800 has been described above). During the transfer, the heating element conveyor belt 100 will transport the next batch of PTC ceramic heating elements 800 to the first designated area 1a and stop there. After completing one grab-transfer-release action, the encoder robot 300 returns to the first designated area 1a and continues to perform the second grab-transfer-release action. Then, the grab-transfer-release action is repeated until all the slots 910 on the copper disk 900 are filled with PTC ceramic heating elements 800.

[0070] Subsequently, the second positioning device 210 releases the copper disk 900, and the copper disk conveyor belt 200 starts running, conveying the copper disk 900 to the subsequent printing process, while also conveying the next copper disk 900 to be stacked to the second designated area 2a; then, the previous action is repeated to fill all the slots 910 of the next copper disk 900 with PTC ceramic heating elements 800.

[0071] In summary, the encoder provided by this utility model, by setting up an adsorption module 310, a lifting mechanism 320, a multi-axis motion module 330, and a variable pitch module 340, can replace manual encoders, realize automatic encoders for PTC ceramic heating elements, improve encoder efficiency and accuracy, reduce labor costs, and effectively solve the problems of low efficiency, high labor intensity, high labor costs, and potential stacking position deviations due to fatigue that exist in traditional manual encoder operations.

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.
