Detailed Description
The invention is described in detail below with reference to the figures and examples.
In the first embodiment, referring to fig. 1 and 2, the riveting and stamping device includes a worktable 1, a positioning block 2 is fixedly connected to the worktable 1 through bolts, and the positioning block 2 is in a vertical flat plate-shaped structure.
The positioning block 2 is provided with a positioning groove 21, and the positioning groove 21 penetrates through the positioning block 2 in the thickness direction of the positioning block 2 and is opened at the upper part. The thickness of the positioning block 2 is smaller than the length of the conductive terminal at the end part of the electrode plate and is matched with the diameter of the conductive terminal.
The workbench 1 is fixedly connected with an installation frame 11 through bolts, the installation frame 11 is in an inverted L shape, a base is formed at one end of the installation frame, and the base is fixedly connected to the workbench 1 through bolts. The lateral upper end of the mounting frame 11 extends above the positioning block 2 and is perpendicular to the extending direction of the positioning groove 21.
Above the positioning block 2, a punching assembly 3 is provided, the punching assembly 3 includes a cylinder 32 fixedly mounted at the horizontal upper end of the mounting frame 11, the cylinder body of the cylinder 32 is fixedly connected to the mounting frame 11, and the piston rod extends vertically downward.
A pressing block 31 is fixedly connected to the end of the piston rod of the cylinder 32, and the pressing block 31 is located above the positioning groove 21. The pressing block 31 is transversely provided with a pressing groove 311, the pressing groove 311 is arranged parallel to the positioning groove 21, transversely penetrates through the pressing block 31, and is of an arc-shaped structure with a downward opening.
In order to ensure that the pressing block 31 can move downwards without being interfered by the positioning block 2, the pressing block 31 is positioned on one side surface in the length direction of the pressing groove 311, the positioning block 2 is positioned on one side surface in the length direction of the positioning groove 21, and the two side surfaces are positioned on the same longitudinal plane, namely the positioning block 2 is staggered after the pressing block 31 moves downwards.
When in use, a user holds one end of the electrode plate, and places the conductive terminal connected with the electrode plate in the positioning groove 21, wherein the opening of the conductive terminal faces upwards. The subsequent control cylinder 32 extends to drive the pressing block 31 to move downwards, so that the pressing groove 311 is gradually covered on the upper part of the conductive terminal. Because the pressing slot 311 is arc-shaped and the opening of the conductive terminal is upward, as the pressing slot 311 gradually moves downward, the two sides of the opening of the conductive terminal are gradually closed by the inner wall of the pressing slot 311 to close the conductive terminal, thereby achieving the purpose of clamping and fixing the conductive wire.
Referring to fig. 3, in order to prevent the end of the conductive terminal extending out of the positioning slot 21 from bending downward due to no support at the lower part when the pressing block 31 (labeled in fig. 2) presses and closes the opening of the conductive terminal, an auxiliary supporting block 22 is formed on the side surface of the positioning block 2. The upper end surface of the auxiliary supporting block 22 is flush with the bottom surface of the positioning slot 21, the length of the auxiliary supporting block extends along the extending direction of the positioning slot 21, and the width of the auxiliary supporting block is less than or equal to the width of the conductive terminal.
When in use, the part of the conductive terminal extending outside falls on the auxiliary supporting block 22 to avoid the situation of bending under stress, and meanwhile, the width of the auxiliary supporting block 22 is less than or equal to that of the conductive terminal, so that the pressing block 31 is not hindered.
The use process comprises the following steps: a user holds one end of the electrode plate, places the conductive terminal connected with the electrode plate in the positioning groove 21, and the opening of the conductive terminal faces upwards; the following user puts one end of the conductive wire exposed out into the conductive terminal, and then controls the cylinder 32 to extend to drive the pressing block 31 to move downwards, so that the pressing groove 311 is gradually covered on the upper part of the conductive terminal to gradually press and fold the conductive terminal, so that the conductive terminal clamps and fixes the conductive wire, and the electrode plate is connected with the conductive wire.
The conductive terminals and the wires of the electrode plates can be connected by using the riveting and stamping device, so that the processing efficiency is higher, and the conductive terminals and the wires can be ensured to be connected after equipment is debugged due to mechanical punching and riveting, and the influence of manual operation on the quality of processed products is reduced as much as possible.
In the second embodiment, referring to fig. 4 and 5, the riveting and stamping device is different from the first embodiment in that: the positioning block 2 is located right below the pressing block 31, or two ends of the pressing groove 311 extend to right above two sides of the positioning block 2 respectively; at this time, the worker places the conductive terminal so that the two ends of the conductive terminal fall on the two sides of the positioning block 2 respectively, and the pressing block 31 is stressed uniformly when the conductive terminal is stamped, so that the purpose of preventing the conductive terminal from bending is achieved.
Since the press block 31 falls and the positioning block 2 blocks the fall, the press block 31 is provided with an intermediate groove 312 that fits the positioning block 2, and the intermediate groove 312 is open downward. When the press block 31 presses and closes the conductive terminals, the positioning block 2 is disposed in the slot 312 to ensure that the movement of the press block 31 is not hindered.
Referring to fig. 5 and 6, the press unit 3 is connected to the safety brake mechanism 4 because the press block 31 is pressed against the user's finger or the like due to manual operation required for the riveting press device in actual use, and in this case, if the user carelessly operates the press unit. The safety brake mechanism 4 comprises a sensor 41 and a data processing controller 42 electrically connected with the sensor, wherein the sensor 41 can be a human body infrared sensor, and the data processing controller 42 is an MCU. The sensor 41 is installed and fixed in the pressing block 31, the detection end of the sensor faces the positioning groove 21, and a hole for detecting the detection line of the sensor 41 is formed in the pressing block 31; the data processing controller 42 is electrically connected to the control unit of the air cylinder 32, and has a standard value prestored therein, which represents that the user does not place a finger or the like under the pressure block 31.
When the finger of the user is carelessly placed below the pressing block 31, the detection value output to the data processing controller 42 by the sensor 41 does not conform to the standard value, and at the moment, the data processing controller 42 controls the air cylinder 32 to stop so as to avoid injury to the user
In a third embodiment, a process for manufacturing a PTC heating bar using a riveting and stamping apparatus, according to the first embodiment, includes:
preparing materials S1, including preparing or purchasing PTC sheets, electrode plates, plastic paper and wires;
preliminary treatment S2, including stripping the wire with a wire stripper, connecting the conductive terminal of the electrode plate with one end of the stripped wire with a riveting and punching device, and cutting the plastic paper into a plurality of pieces of plastic paper with a computer belt cutter;
the preliminary forming step S3 includes taking two electrode plates connected with leads and a PTC sheet, clamping the PTC sheet by the two electrode plates connected with the leads, and ensuring the leads to be in the same orientation;
molding S4, taking plastic paper, tightly winding the plastic paper outside the two electrode plates which are molded at the beginning (S3) and performing heat sealing to form a PTC heating strip;
and (5) quality testing S5, wherein an insulation and voltage resistance testing device 5 is arranged to perform insulation and voltage resistance detection on the PTC heating strips.
The preparation S1 further includes preparing or purchasing a sleeve fitting the conductive terminal, where the sleeve is made of plastic and actually fits the conductive terminal with the opening closed. When the cutting machine is used, a user firstly adopts the computer pipe cutting machine to cut the sleeve into a plurality of character sleeves; when the conductive terminal and the lead are connected under the action of the riveting and stamping device, a user takes the sub-sleeve, sleeves the sub-sleeve from the free end of the lead, and gradually slides to the outside of the conductive terminal to sleeve the conductive terminal. At the moment, the conductive terminal can be prevented from being broken open through the sub-sleeve, namely, the conducting wire is loosened, so that the connecting effect of the conductive terminal and the conducting wire can be further ensured, and the product quality is ensured.
Referring to fig. 8, the withstand voltage testing apparatus 5 includes a clamping plate group 51 and a withstand voltage tester 52. The clamping plate group 51 comprises a bottom plate 511 and a pressure plate 512, and the vertical projections of the bottom plate 511 and the pressure plate 512 are rectangular and have substantially the same size. The bottom plate 511 and the pressing plate 512 are hinged to each other at one side by a hinge, and the hinge direction is a longitudinal direction. The base plate 511 is positioned below the platen 512 and is secured in place.
The insulation withstand voltage tester 52 includes a body, a grounding conductive clip connected to the body, and a test bar connected to the body. The upward end surface of the pressing plate 512 is fixedly connected with a conductive ring, a grounding clamp of the insulation withstand voltage tester 52 is clamped on the conductive ring and electrically connected to the pressing plate 512, and the pressing plate 512 has conductivity to complete grounding.
When in use, a user places a plurality of PTC heating strips on the bottom plate 511 side by side, then rotates the pressing plate 512 to press the PTC heating strips, and leads of the PTC heating strips extend out of the pressing plate 512; a subsequent user only needs to hold the test rod of the insulation withstand voltage tester 52 and repeatedly pass the test rod on the lead extending out of the PTC heating strip for multiple times; when a certain PTC heating strip is not qualified, the leakage problem occurs, and the insulation withstand voltage tester 52 sends out prompt information to prompt a user. For convenience of use, the insulation withstand voltage tester 52 is an insulation withstand voltage tester with an audible and visual alarm function.
Since the test bar of the insulation withstand voltage tester 52 is required to be passed over the lead of the PTC heating strip during the above operation, and the lead has a certain rigidity, a part of the PTC heating strip is distorted to interfere the test of the test bar with other PTC heating strips when the test bar is passed over the lead, and thus the pressing block 53 is provided. The pressing block 53 is made of an insulating material, and a handle 531 is fixed to an upper portion thereof.
After the pressing plate 512 presses the PTC heating strip, the user can hold the handle 531 to press the pressing block 53 on the pressing plate 512, and then move the pressing block 53 while moving the test rod, so that the pressing plate 512 presses the PTC heating strip to prevent the movement of the PTC heating strip from affecting the test effect.
When testing the PTC heating strips, since it is necessary to arrange them on the bottom plate 511 in the transverse direction and to avoid the situation that the lead of a certain PTC heating strip is not contacted when the test bar is scratched, a leveling straight plate 54 is further provided, and the leveling straight plate 54 is in the shape of a long plate.
When in use, the leveling straight plate 54 is arranged at the opposite side of the PTC heating strip without the conducting wire and is abutted against the bottom plate 511 to keep the state of being parallel to the side edge of the bottom plate 511; then, a user only needs to arrange the plurality of PTC heating strips and keep the end part of the PTC heating strips in a state of abutting against the leveling straight plate 54, at the moment, the PTC heating strips are arranged orderly, and the lead is relatively orderly, so that the test effect when the follow-up test rod scratches the lead can be ensured.
The thickness of the leveling straight plate 54 is smaller than that of the PTC heating bars so that the leveling straight plate 54 can be directly placed on the base plate 511 after use for the next operation by the user.
The use process comprises the following steps:
1. picking up a plurality of PTC heating strips and placing them on the base plate 511 primarily to ensure that the ends of the PTC heating strips face the same direction (with the ends of the leads facing outward);
2. taking the leveling straight plate 54 up from the upper bottom plate 511, adjusting the position of the leveling straight plate 54 to enable the leveling straight plate to be arranged at the end without the conducting wire of the PTC heating bar, keeping the leveling straight plate parallel to the side edge of the bottom plate 511 and abutting against the bottom plate 511;
3. separating each PTC heating strip, and enabling one end without a lead to respectively abut against the leveling straight plate 54 so as to arrange a plurality of PTC heating strips in order; at this time, the lead portions of the plurality of PTC heating bars protrude out of the pressing plate 512;
4. rotating the pressing plate 512 to press the PTC heating bar, and then holding the handle 531 to move the pressing block 53 onto the pressing plate 512;
5. and starting the insulation withstand voltage tester 52, holding the test rod connected with the insulation withstand voltage tester, and scratching the test rod from the leads of the plurality of PTC heating strips to finish the test. When a certain PTC heating strip has a problem of electric leakage, the insulation withstand voltage tester 52 sends out a prompt message to prompt a user.
Because the riveting and punching device is adopted to realize the connection work at the connection stage of the conductive terminals and the leads of the electrode plate, the connection quality of the electrode plate and the leads can be improved; meanwhile, the PTC heating strips are subjected to voltage withstanding test by using the insulation voltage withstanding test device 5 before the electrode plates leave the factory, so that the quality of the PTC heating strips leaving the factory can be further improved, and the quality of the electrical equipment processed by using the PTC heating strips is ensured.
