Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to a tape punching equipment. Background Art

[0002] Tape used for mounting related equipment components (for example, tape used for securing components in electronic products, primarily used for securing and bonding LCD display frames, nameplates, and LCD buffers, as well as cable trays; tape used in production applications such as power distribution cabinets, for bonding and securing lightweight monitoring sensors). In some production areas, tape may require intermittent perforations to enhance heat dissipation.

[0003] In the prior art, for the punching operation of the tape, the staff generally holds the punching device and aligns the lower punching part (pointed cone, hollow circle, etc., hereinafter referred to as the punching head) with the punching surface of the tape, and then punches a hole at the corresponding part of the upper end of the tape, or the punching head of the electrically driven punching device moves downward to punch the corresponding part of the tape. Although the existing punching equipment meets the punching needs to a certain extent, it still has the following technical problems due to structural limitations. Specifically, the number of punching heads of the existing punching equipment is fixed. Sometimes, when it is necessary to change the different punching spacing of the tape, then only punching equipment with different punching head spacing can meet the actual needs. In this way, due to the relatively large number of punching equipment equipped, it will bring relatively more equipment and capital investment to the manufacturer. In addition, the existing electric punching equipment controls the upward and downward movement of its punching head by manually operating the power switch and controlling the forward and reverse rotation of the motor shaft that drives the punching head (for example, the driving motor shaft rotates forward and the related mechanism drives the punching head downward, and the driving motor shaft rotates reversely and the related mechanism drives the punching head upward); the above-mentioned operation method, especially for continuous and uninterrupted punching of the tape, will bring great inconvenience to the relevant operators, and is correspondingly not conducive to improving efficiency.

The heating shell 64 is a hollow structure. The two sets of electric heating plates RT are longitudinally installed on both sides of the heating shell 64. The upper end of the cylinder of the electric push rod M1 is vertically distributed and installed in the middle of the lower side of the support frame 65. The upper ends of the bearing seats of the two sets of guide linear bearings 62 are respectively welded to the front and rear parts of the lower side of the support frame 65. The push column of the electric push rod M1 and the shafts of the two sets of guide linear bearings 62 The lower ends of the supporting rods are welded to the outer side of the upper end of the heating shell 64 at a distance from each other; the temperature control switch S1 is installed on the outer side of the upper end of the heating shell 64 and its temperature sensing surface is close to the outer side of the upper end of the heating shell 64. The lower end of the heating shell 64 is distributed with a plurality of continuous wire holes 66 from left to right, and there are multiple punching heads 63. A screw rod 631 is welded to the middle part of the upper end of each punching head 63, wherein the upper ends of the plurality of punching heads are respectively screwed into the plurality of wire holes 66 at the lower end of the heating shell through the upper end of the screw rod 631 and installed on the outer side of the lower end of the heating shell 64; a "Π"-shaped door frame 10 is respectively welded on the front and rear sides of the fixing plate on the middle part of the bottom plate 3, and the lower ends of the front and rear sides of the support frame 65 are respectively welded to the outer middle part of the upper ends of the two door frames 10;The power module A1 and control circuit 5 are mounted on a circuit board within a component box 9, which is mounted on the front left end of the base plate 3. Pins 1 and 2 of the power input of the power module A1 and the power input of the electric heating plate RT are connected in series via a temperature control switch S1 and are connected to the two poles of the AC 220V power supply via wires. Pins 3 and 4 of the power output of the power module A1 are connected to pins 1 and 2 of the control circuit's power input, time-controlled switches A2, A3, and A4, respectively, via wires. Pins 3 and 4 of the control circuit's power output, time-controlled switch A2, are connected to the positive and negative power inputs of the motor reduction mechanism M, respectively, via wires. Pins 3 and 4 of the time-controlled switches A3 and A4 are connected to the positive and negative, and negative and positive, power inputs of the electric push rod M1, respectively, via wires.

[0018] Figure 1 、 2 As shown in Figures 3 and 4, the control circuit includes three time-controlled switches A2, A3, and A4 connected via circuit board wiring. The power input pins 1 and 2 of the three time-controlled switches A2, A3, and A4 are connected via wires. The lower end of each punching head 63 is a circular, open structure with a tapered blade on the lower outer side. The lower ends of multiple punching heads 63 are horizontal. The leading ends of the multiple loops of tape 81 wound on the tape roll are guided rightward through the lower ends of the two guide mechanisms' rotating drums 42 (which guide and limit the tape's movement) and wound onto the reel 21 of the reel. The longitudinal width of the multiple punching heads 63 at the lower end of the heating shell is slightly smaller than that of the tape 81. The heating shell is also equipped with multiple screw plugs 11, which are threadedly mounted within the threads at the lower end of the heating shell 64.

[0019] Figure 1 、 2As shown in Figure 3, after the main power switch is turned on and the power module A1 is energized, its 3rd and 4 pins output a stable DC 12V power supply which enters the power input terminal of the control circuit. At the same time, the AC 220V power supply enters the power input terminal of the two electric heating plates RT through the temperature control switch S1. The two electric heating plates RT are energized to heat the heating shell, and the high heat radiated by the heating shell acts on the multiple punching heads 63, and the multiple punching heads gradually heat up (about 250°C); when the temperature of the heating shell is lower than 250°C, the internal contacts of the temperature control switch S1 are closed, and then the two electric heating plates RT are energized to heat up. When the temperature of the heating shell is higher than 250°C, the internal contacts of the temperature control switch S1 are open, and then the two electric heating plates RT lose power and do not heat up. Through the above, the present invention can ensure that the temperature of the multiple punching heads is about 250°C during operation. After the time-controlled switch A2 is energized, it will output 2 seconds (time is adjustable) of power at intervals of 6 seconds to the positive and negative power input terminals of the motor reduction mechanism M. Then, the motor reduction mechanism M is energized and its shaft drives the reel 21 to rotate and rewind the punched tape (the section of tape reeled at the front end of the reel is not punched and can be used for other purposes or opened manually later); after the time-controlled switches A3 and A4 are energized, during the 6-second power output time of the time-controlled switch A2, the 3rd and 4th pins of the time-controlled switch A3 will output power for 3 seconds. A power source (adjustable time) is supplied to the positive and negative power input terminals of the electric push rod M1. Pins 3 and 4 of the time-controlled switch A4 then output power (adjustable time) for 3 seconds to the positive and negative power input terminals of the electric push rod M1. During the time the positive and negative power input terminals of the electric push rod M1 are energized, its push rods push the multiple punching heads 63 downward to their stop point (just enough to contact the engineering plastic fixing plate 7). The multiple punching heads then, through heat fusion and the action of the tapered blades at their lower ends, form multiple holes in a row longitudinally along the tape. During the time the positive and negative power input terminals of the electric push rod M1 are energized, its push rods drive the multiple punching heads 63 upward to their stop point, thereby separating the multiple punching heads from the top of the tape, preparing for the next punching. Through this process, the present invention can continuously punch holes in the tape roll horizontally, left and right. In actual situations, the staff can add or reduce the number of 63 punching heads according to actual needs through threads at the lower end of the heating shell, thereby achieving the purpose of punching holes with different longitudinal spacing on the surface of the tape (if more 63 punching heads are used, the number of longitudinal holes punched is relatively large and the spacing between each two holes is close; on the contrary, if fewer 63 punching heads are used, the number of longitudinal holes punched is relatively small and the spacing between each two holes is large. A screw plug is installed through threads at the position where no punching head is installed. The height of the lower end of the screw plug is 1 cm higher than the lower end of the punching head, and it will not touch the upper end of the tape when descending).After all the holes in the tape of one circle of the tape roll 8 of the present invention are punched, the staff unscrews the screw on the front side of the right end for installing the bearing seat 24, removes the bearing seat 24, then pulls out the bearing toward the front end, removes the reel 21 (there are multiple sets), and then inserts a new reel and bearing seat, and rotates the shaft 81 in the middle of the left and right ends of the new tape roll 8 respectively to install it in the guide grooves 71 of the two support frames, and then starts the next batch of tape punching work.

Operating the seven setting buttons separately can set the power output time and interval output power time of the two power output terminals; the electric heating plate RT is a 300W constant temperature ceramic PTC heating plate (heating temperature 300℃); the motor reduction mechanism M is a coaxial motor gear reducer with a working voltage of DC 12V and a power of 100W; the electric push rod M1 is a finished product of a reciprocating electric telescopic rod with a power of 50W.
