Description

Technical Field

[0001] This utility model relates to the field of ceramic heating element production technology, and in particular to a copper disc conveying device. 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, the PTC ceramic heating elements need to be stacked one by one onto a copper plate (this process is referred to as plate stacking) before the printing process. Traditional plate stacking operation relies entirely on manual operation, which has the following disadvantages: (1) The copper plate is picked up and placed and the PTC ceramic heating elements are stacked manually, which is inefficient and labor-intensive; (2) The labor cost is high, especially in mass production, multiple operators are required; (3) Manual operation is prone to fatigue, which can lead to deviation in the stacking position and affect the printing accuracy.

[0004] Therefore, it is necessary to automate the disk stacking process to address some of the shortcomings of the current manual disk stacking operation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a copper disk conveying device that allows copper disks located in predetermined positions to be conveyed one by one to a designated position in the PTC ceramic heating element stacking process, so as to wait for the PTC ceramic heating elements to be stacked on the copper disk.

[0006] The technical solution adopted by this utility model to solve its technical problem is: to provide a copper disc conveying device, which includes a lifting device, a copper disc transfer device and a conveyor belt;

[0007] The lifting device includes a lifting platform and a lifting drive mechanism; the upper surface of the lifting platform is used to support stacked copper disks; the lifting drive mechanism is used to drive the lifting platform to move vertically up and down, and during the process of the copper disk being transferred by the copper disk transfer device, the lifting drive mechanism cooperates with the transfer action of the copper disk transfer device to drive the lifting platform to move up intermittently, so that each time the transfer is carried out, the next copper disk to be transferred moves to the predetermined disk retrieval position in advance;

[0008] The copper tray transfer device is located on the side of the lifting device and is used to pick up the copper tray located at the tray picking position on the lifting platform and transfer it to the conveyor belt;

[0009] The conveyor belt is located downstream of the lifting device and is used to receive the copper disk released by the copper disk transfer device and transport it to a subsequent designated location.

[0010] Furthermore, the copper tray conveying device also includes a copper tray temporary storage area configured in conjunction with the lifting platform;

[0011] The copper tray storage area is equipped with guide rails, and stacked copper trays can be guided from the copper tray storage area to the lifting platform at the loading position via the guide rails.

[0012] Furthermore, there are two guide rails, which are arranged on the left and right sides of the lifting platform.

[0013] Furthermore, the guide rail includes multiple rollers arranged in a straight line and at the same height, so that the copper disk is driven by an external force to slide above the rollers, so as to move from the copper disk temporary storage area to the lifting platform at the loading position.

[0014] Furthermore, a limit baffle is provided around the periphery of the lifting platform to limit the copper plate so that it does not deviate during the upward movement.

[0015] Furthermore, there are two limiting baffles distributed on the left and right sides of the lifting platform, and the cross-section of the limiting baffles is L-shaped, with the two sides of the L-shape used to limit the long side and the wide side of the copper disk, respectively.

[0016] Furthermore, the copper disk transfer device includes a suction cup assembly, a cylinder, and a linear motion module;

[0017] The suction cup assembly is used to adsorb the copper disk;

[0018] The piston rod of the cylinder is connected to the suction cup assembly and is used to drive the suction cup assembly to move up and down.

[0019] The slider of the linear motion module is fixed relative to the cylinder, and is used to drive the cylinder and the suction cup assembly to reciprocate in the horizontal direction, so that the suction cup assembly moves between the lifting platform and the conveyor belt.

[0020] Furthermore, the suction cup assembly is provided with four suction nozzles, which are used to adsorb the four corners of the copper disk respectively.

[0021] Furthermore, the linear motion module is a lead screw module.

[0022] Furthermore, the lifting device is equipped with an infrared sensor, which is used to position the uppermost copper disk on the lifting platform when the copper disk transfer device picks up the copper disk, so that it is in the disk picking position.

[0023] The beneficial effects of this utility model are as follows:

[0031] 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.

[0032] See Figures 1 to 3 This utility model provides a copper disc conveying device, which includes a lifting device 100, a copper disc transfer device 200, and a conveyor belt 300.

[0033] The lifting device 100 includes a lifting platform 110 and a lifting drive mechanism 120. The upper surface of the lifting platform 110 is used to support stacked copper disks a. The lifting drive mechanism 120 is used to drive the lifting platform 110 to move vertically up and down. During the process of the copper disk a being transferred by the copper disk transfer device 200, the lifting drive mechanism 120 will cooperate with the transfer action of the copper disk transfer device 200 to drive the lifting platform 110 to move up intermittently, so that each time the next copper disk a to be transferred is moved to the predetermined pick-up position in advance; that is, during the process of the copper disk transfer device 200 picking up the previous copper disk a and completing the transfer of the copper disk a, the lifting drive mechanism 120 will drive the lifting platform 110 to move up one unit height, so that the next copper disk a moves to the pick-up position, waiting for the copper disk transfer device 200 to pick it up.

[0034] The copper plate transfer device 200 is disposed on the side of the lifting device 100 and is used to pick up the copper plate a located at the plate picking position on the lifting platform 110 and transfer it to the conveyor belt 300.

[0035] The conveyor belt 300 is disposed on the downstream side of the lifting device 100 and is used to receive the copper disk a released by the copper disk transfer device 200 and transport it to a subsequent designated position.

[0036] In a preferred embodiment, see Figure 2 The copper tray conveying device of this utility model also includes a copper tray temporary storage area 400 that is configured in conjunction with the lifting platform 110. The copper tray temporary storage area 400 is provided with a guide rail 410, and the stacked copper trays a can be guided from the copper tray temporary storage area 400 onto the lifting platform 110 which is in the loading position by means of the guide rail 410.

[0037] Preferably, there are two guide rails 410, and the corresponding lifting platform 110 is arranged on the left and right sides of them.

[0038] Furthermore, the guide rail 410 includes a plurality of rollers 411 arranged in a straight line and of the same height, so that the copper disk a is driven by an external force to slide above the rollers 411, so as to move from the copper disk temporary storage area 400 to the lifting platform 110 which is in the loading position.

[0039] Among them, see Figure 2 The guide rail 410 further includes a guide rail groove 412, and the roller 411 is rotatably disposed in the guide rail groove 412. The two guide rail grooves 412 are fixed on a mounting platform 500 at a predetermined distance and parallel to each other.

[0040] The loading position is the lowest point of the vertical movement of the lifting platform 110 (e.g., ...). Figure 2The position of the lifting platform 110 is the highest point during the vertical movement of the lifting platform 110 (e.g., the position of the lifting platform 110). Figure 5 The position of the lifting platform 110). And when in the loading position, the upper surface of the lifting platform 110 is slightly lower than the upper surface of the guide rail 410 (see...). Figure 2 This ensures that after the copper plate a in the copper plate temporary storage area 400 moves horizontally along the guide rail 410, it can move to the top of the lifting platform 110, so that the lifting platform 110 can lift the copper plate a later.

[0041] During operation, in the initial state, the lifting platform 110 is in the loading position at the lowest point of its stroke (i.e., ...). Figure 2 (as shown in the image). At this time, the operator manually places a stacked copper plate a in the copper plate temporary storage area 400, and then manually pushes the copper plate a, which will slide above the roller 411 and move it above the lifting platform 110. Then, the lifting platform 110 can lift the copper plate a, raising the uppermost copper plate a to the plate retrieval position.

[0042] In a preferred embodiment, see Figure 2 The lifting platform 110 is provided with a limit baffle 130 on its periphery to limit the copper disk a so that it does not deviate during the upward movement, thus ensuring the stable movement of the copper disk a.

[0043] Preferably, there are two limiting baffles 130, which are located on the outside of the two guide rails 410 and fixed at the bottom to the mounting platform 500.

[0044] Furthermore, the cross-section of the limiting baffle 130 is L-shaped, and the two sides of the L-shape are used to limit the long side and the wide side of the copper disk a, respectively.

[0045] In a preferred embodiment, see Figure 2 The lifting device 100 also includes a base plate 150, a guide rod 160, a sliding sleeve 170, a movable plate 180, and a connecting rod 190. The lifting drive mechanism 120 includes a first motor 121, a transmission mechanism, a lead screw 122, and a lead screw nut 123.

[0046] The base plate 150 is spaced below the mounting platform 500.

[0047] There are four guide rods 160 arranged in a rectangular shape. The top of each guide rod 160 is fixed to the lower surface of the mounting platform 500, and the bottom is fixed to the upper surface of the base plate 150.

[0048] There are four sliding sleeves 170, which are slidably sleeved on four guide rods 160 respectively.

[0049] The movable plate 180 is sleeved on the four guide rods 160 and fixed to the four sliding sleeves 170. Thus, the movable plate 180 can move up and down along the guide rods 160 with the help of the sliding sleeves 170.

[0050] There are four connecting rods 190 arranged in a rectangular shape. The top of each connecting rod 190 passes through the mounting platform 500 and is fixed to the lower surface of the lifting platform 110, while the bottom is fixed to the upper surface of the movable plate 180, so that the lifting platform 110 and the movable plate 180 form a whole that can move up and down together.

[0051] The first motor 121 is mounted on the base plate 150.

[0052] The lead screw 122 passes through the base plate 150 and the movable plate 180 from bottom to top, and is rotatably connected to the bottom of the mounting platform 500.

[0053] The lead screw nut 123 is threadedly fitted onto the lead screw 122 and is fixed to the movable plate 180.

[0054] The transmission mechanism (not shown in the figure) is located below the base plate 150. The transmission mechanism is connected between the output shaft of the first motor 121 and the bottom end of the lead screw 122, and is used to transmit the torque of the output shaft of the first motor 121 to the lead screw 122, thereby driving the lead screw 122 to rotate.

[0055] Therefore, when the first motor 121 operates, it drives the lead screw 122 to rotate via the transmission mechanism. The rotation of the lead screw 122, in turn, drives the movable plate 180 to move up or down along the guide rod 160 via the lead screw nut 123. Since the lifting platform 110 is connected to the movable plate 180 via the connecting rod 190 to form a whole that can move up and down together, the rotation of the first motor 121 ultimately realizes the up and down movement of the lifting platform 110.

[0056] In a preferred embodiment, see Figure 3 The copper disk transfer device 200 includes a suction cup assembly 210, a cylinder 220, and a linear motion module 230.

[0057] The suction cup assembly 210 is provided with four suction nozzles 211, which are distributed and fixed on the four corners of a suction cup plate 212, respectively for adsorbing the four corners of the copper disk a.

[0058] The piston rod of the cylinder 220 is connected to the suction cup plate 212 and is used to drive the suction cup assembly 210 to move up and down.

[0059] The sliding block 231 of the linear motion module 230 is connected to a vertically arranged fixed plate 240, and the cylinder 220 is fixed to the fixed plate 240. Thus, the linear motion module 230 can drive the fixed plate 240, the cylinder 220, and the suction cup assembly 210 to reciprocate horizontally, so that the suction cup assembly 210 moves between above the lifting platform 110 and above the conveyor belt 300.

[0060] Preferably, the linear motion module 230 is a commonly used lead screw module. Of course, the linear motion module 230 can also be a synchronous belt module, which is also a commonly used linear motion module.

[0061] Additionally, see Figure 2 In this utility model, the lifting device 100 is also equipped with an infrared sensor 140. The infrared sensor 140 is used to position the uppermost copper disk a on the lifting platform 110 when the copper disk transfer device 200 picks up the copper disk a, so that it is in the disk picking position.

[0062] The working principle of the copper disc conveying device of this utility model is as follows:

[0063] Initially, the lifting platform 110 is at its lowest point of travel, ready to be loaded, and the suction cup assembly 210 is positioned directly above the lifting platform 110; the operator places a stack of copper trays a into the copper tray storage area 400 (see...). Figure 4 Subsequently, the operator manually pushes copper plate a, allowing it to slide above roller 411 and move above lifting platform 110.

[0064] After the copper plate a in the copper plate temporary storage area 400 is pushed above the lifting platform 110, the first motor 121 of the lifting drive mechanism 120 starts to work, and drives the lead screw 122 to rotate, causing the lifting platform 110 to rise vertically, so that the uppermost copper plate a moves up to the plate retrieval position.

[0065] Then, cylinder 220 operates in the forward direction, driving the suction cup assembly 210, which is positioned directly above the lifting platform 110, to move downwards. After moving downwards, the four suction nozzles 211 of the suction cup assembly 210 move to the disk-retrieving position and attach to the four corners of the uppermost copper disk a. Subsequently, the air pump connected to the suction nozzles 211 draws air, causing the four suction nozzles 211 to hold the copper disk a. (See below) Figure 5 ;

[0066] Then, cylinder 220 reverses its direction, driving suction cup assembly 210 upward to a predetermined height; subsequently, linear motion module 230 operates, causing suction cup assembly 210 to move horizontally above conveyor belt 300. During this process, the adsorbed copper disk a moves along with suction cup assembly 210 above conveyor belt 300; then, cylinder 220 operates in the forward direction, driving suction cup assembly 210 downward. When copper disk a moves close to conveyor belt 300, the air pump connected to suction nozzle 211 stops suction, causing suction nozzle 211 to release copper disk a, allowing it to fall onto conveyor belt 300 (see...). Figure 6 Then, the copper plate a will be conveyed by the conveyor belt to the next designated position to wait for the PTC ceramic heating element to be engraved.

[0067] Therefore, the copper disc conveying device of this invention, in the PTC ceramic heating element stacking process, enables the stacked copper discs a to be transferred one by one onto the conveyor belt 300, and then transported by the conveyor belt 300 to a designated position awaiting PTC ceramic heating element stacking. It automates the process of picking up and placing copper discs in the stacking process, thus improving work efficiency, reducing manual labor intensity, and lowering labor costs. It can also be used in conjunction with other further developed automated equipment to achieve fully automated stacking operations that replace manual labor.

[0068] 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.
