Fig. 1 is a schematic perspective view of an automatic spot-weld machine for electrode plates and terminals in the embodiment, where the automatic spot-weld machine 1 includes: the electrode plate feeding mechanism comprises a bracket, an electrode plate guide groove 10 arranged on the bracket, and an electrode plate feeding mechanism 20, a terminal feeding mechanism 30, a butt-welding mechanism 40 and a blanking mechanism 50 which are sequentially arranged along the + x direction.
As shown in the figure, the rightmost end of the guide groove is an electrode plate introduction port, a prepared and molded electrode plate 60 is manually or automatically introduced into the electrode plate introduction port, an induction device is arranged at the electrode plate introduction port, when the induction device detects that an electrode plate is introduced, the electrode plate feeding mechanism 20 feeds the electrode plate to the butt-welding mechanism 40 through the electrode plate guide groove, and when the electrode plate feeding mechanism 20 reaches the right end of the butt-welding mechanism 40, the terminal feeding mechanism 30 feeds the terminal to the electrode plate feeding mechanism 20, so that the terminal and the electrode plate 60 are overlapped; the overlapped terminals are then fed together with the electrode sheet 60 by the electrode sheet feeding mechanism 20 into the butt-welding mechanism 40 and welded. The welded terminal and electrode sheet 60 are taken out of the butt-welding mechanism 40 by the blanking mechanism 50 and blanked.
In order to realize the automation of the butt-welding of the electrode tab 60 and the terminal, the electrode tab 60 and the terminal are specially designed, and fig. 2 and 3 are respectively schematic structural views of the electrode tab and the terminal in the present embodiment. As shown in fig. 2, the electrode plate 60 has a conventional elongated structure adapted to various types of PTC heating elements, but a vertical edge protrusion 61 is provided on each side of one end of the electrode plate 60, the vertical edge protrusion 61 is used for mating with a terminal, and a portion surrounded by the vertical edge protrusion is a butt-welding region 62. The protruding piece thickness of stile in this embodiment is 0.2mm, and its piece thickness can carry out the setting of other specifications according to actual need. As shown in fig. 3, the terminal 70 is composed of three sections having gradually decreasing widths, and is integrally formed. The center of the third section 73 is provided with a traction hole 731 used for matching with the blanking mechanism 50; the second section 72 is a butt-welded region of the terminal, and the second section 72 cooperates with one end of the electrode tab 60 in conjunction with the first section 71. Since the electrode tab 60 and the terminal 70 are butt-welded, one end of the electrode tab 60 is overlapped with the terminal 70; when the terminal 70 is stacked on one end of the electrode tab 60, the two standing projections 61 of the electrode tab are enclosed outside the second section 72 of the terminal, and the rear side (-x direction) of the standing projection abuts on the front side of the first section 71 of the terminal. With the terminal and the electrode tab constructed as above, when they are overlapped together, they can be collectively and stably fed into the butt-welding mechanism by the electrode tab feeding mechanism 20. In this embodiment, the electrode plate and the terminal are made of stainless steel.
Fig. 4 is a schematic structural diagram of an electrode plate feeding mechanism, wherein the electrode plate feeding mechanism 20 includes a first pushing unit 21 and a second pushing unit 22, and the first pushing unit 21 is connected to a first braking mechanism (not shown in the figure) for individually pushing electrode plates; the second pushing unit 22 is connected to a second brake mechanism (not shown) for feeding electrode sheets and terminals to the butt-welding mechanism. When the electrode plate feeding mechanism independently pushes the electrode plates, the first pushing unit 21 and the second pushing unit 22 move forward together; after the terminal feeding mechanism feeds the terminals to the electrode plate feeding mechanism, the second pushing unit 22 is displaced relative to the first pushing unit 21 and moves forward to push the terminals and the electrode plates to the butt-welding mechanism together.
Specifically, as shown in fig. 5 and 6, the second pushing unit 22 includes an ejector 221, and the ejector 221 is pushed by the second stopper mechanism to eject the stacked terminal and electrode tab toward the butt-welding mechanism, and to cause the butt-welding regions of the electrode tab and the terminal to fall into the butt-welding mechanism. In fig. 5-7, the ejector 221 is omitted to provide visual access to the electrode pads, and in fact, the electrode pads fall beneath the terminals and the ejector, and the terminals are pushed by the ejector and are driven by the fixed engagement of the electrode pads and the terminals to eject the electrode pads forwardly.
In order to enable the electrode plate to slide forwards in the electrode plate guide groove more stably before the terminal feeding mechanism feeds the terminal to the electrode plate feeding mechanism and enable the electrode plate and the terminal to slide forwards or be ejected out more stably after the terminal feeding mechanism feeds the terminal to the electrode plate feeding mechanism, an elastic pressing piece is arranged above the ejecting piece. As shown in fig. 7, the elastic pressing member includes a steel ball fixing member 222, steel balls 223 and an elastic pressing plate 224, the steel ball fixing member 222 is used for fixing the steel balls above the ejecting member, the width of the steel ball fixing member 222 is adapted to the width of the electrode plate and can cover the width of the electrode plate, the size and number of the steel balls are determined according to the size and area of the terminal, and only 1 steel ball is shown in the figure. The elastic pressing plate 224 is pressed on the steel balls 223, and applies a downward pressing force to the electrode plate or the terminal. Before the terminal feeding mechanism feeds the terminal to the electrode plate feeding mechanism, the elastic pressing piece presses the electrode plate; and after the terminal feeding mechanism feeds the terminal to the electrode plate feeding mechanism, the elastic pressing piece presses the terminal. The electrode plate or the terminal is applied with downward force through the elastic pressing piece, so that the electrode plate or the terminal is more stable in the forward movement process and cannot jump out of the electrode plate guide groove.
Fig. 8 is a schematic structural view of the terminal feeding mechanism, and as shown in fig. 8, the terminal feeding mechanism includes a vibrating plate 31 and a third pushing unit 32. The vibration plate 31 is used for orderly arranging the terminals to the terminal guide groove 33, and comprises a linear vibration plate and/or a rotary vibration plate. The third pushing unit 32 is used for feeding the terminals in the terminal guide grooves 33 into the electrode plate feeding mechanism 20.
In fig. 1 and 8, the terminal guide groove 33 is disposed at the edge near the butt-welding mechanism 40, and the third pushing unit 32 feeds the terminal into the electrode plate feeding mechanism, which includes the following specific processes: the first pushing unit 21 in the electrode plate feeding mechanism 20 is braked by the first braking mechanism to feed the electrode plate to a position parallel to the terminal guide groove 33, and at this time, the elastic pressing piece (including the steel ball fixing piece 222, the steel ball 223 and the elastic pressing plate 224) is pressed on the electrode plate; then, the terminal is pushed by a third pushing unit in the terminal feeding mechanism 30 to push the steel ball upwards and is pushed to a position between the steel ball and the electrode plate; when the terminal is completely pushed into the space between the two vertical edge bulges of the electrode plate, the terminal falls down due to the pressing effect of the elastic pressing plate, is superposed on the electrode plate and is matched and fixed with the 2 vertical edge bulges of the electrode plate.
When the terminal is fed to the region between the elastic pressing piece and the electrode plate, as shown in fig. 6 and 7, the ejecting piece 221 of the electrode plate feeding mechanism is pushed by the second brake mechanism to eject the terminal and the electrode plate stacked together to the butt-welding mechanism, and the butt-welding region of the electrode plate and the terminal falls into the butt-welding mechanism.
The terminal feeding mechanism is for feeding the terminal to the electrode sheet feeding mechanism, and the terminal guide groove 33 may be provided at an edge close to the butt-welding mechanism as shown in fig. 1 and 8, or may be provided at any position between the electrode sheet introduction port and the butt-welding mechanism. When the terminal guide groove is arranged at other positions, the first pushing unit of the electrode plate feeding mechanism has a part of processes of independently pushing the electrode plate, and the other part of processes of pushing the electrode plate and the terminal.
As shown in fig. 9, the butt welding mechanism 40 includes a butt welding upper copper bar 41 and a butt welding lower copper bar 42 provided above and below the electrode sheet guide groove, respectively, and the butt welding upper copper bar and the butt welding lower copper bar are connected to the electronic box. When the overlapped electrode plates and terminals are pushed to the butt-welding area between the butt-welding upper copper rod and the butt-welding lower copper rod, the butt-welding upper copper rod and the butt-welding lower copper rod discharge through the electric box so as to carry out butt-welding on the electrode plates and the terminals.
After the butt welding is completed, the blanking mechanism 50 performs blanking. Specifically, the blanking mechanism 50 includes a material taking traction unit and a blanking unit. As shown in fig. 10 and 11, the reclaiming traction unit 51 includes a movable hook 511, the hook 511 is matched with the traction hole 731 of the third section of the terminal, the hook 511 is in a downward pressing state in fig. 10, and the hook is in a lifting state in fig. 11. After the butt-welding of the terminal and the electrode plate is completed, the hook 511 is pressed down and fixed with the traction hole 731 of the terminal, and then moves forwards (+ x direction) under the brake of the fourth brake mechanism, so that the butt-welded electrode plate and the terminal are completely pulled out. After the drawing is completed, the hook 511 is lifted, and the air finger 52 fixed above the bracket is braked by a fifth brake mechanism (in fig. 1, the fifth brake mechanism is a horizontal air cylinder 53 and a vertical air cylinder 54) to blank the electrode plate and the terminal which are subjected to butt welding and send the electrode plate and the terminal to equipment of the next process. In fig. 10-11, for ease of illustration, only the terminals, actually the butt-welded terminals and electrode tabs, are shown.
In order to further improve the efficiency of mechanized production, the first braking mechanism connected with the electrode plate feeding mechanism and the fourth braking mechanism connected with the material taking traction unit can be the same braking mechanism, such as: push-and-pull synchronous cylinder, and electrode slice feeding mechanism and getting material traction unit are connected through hold-in range 11 (shown in figure 1). The electrode plate feeding mechanism and the material taking traction unit are respectively connected with two sides of the synchronous belt, and when the push-pull synchronous cylinder works, the electrode plate feeding mechanism and the material taking traction unit move in the opposite direction or move in the opposite direction under the action of the synchronous belt. When the electrode plate feeding mechanism drives the electrode plate to move towards the butt-welding mechanism, the material taking traction unit also moves towards the butt-welding mechanism, and after the butt-welding is finished, the electrode plate feeding mechanism and the material taking traction unit simultaneously depart from the butt-welding mechanism and return to respective initial positions. When the electrode sheet is introduced again, the above operation is repeated. Through hold-in range and push-and-pull synchronizing cylinder, can further promote mechanized production's efficiency to reduce the volume of whole equipment.
In addition, it is understood that: after the butt-welding of the electrode plate and the terminal is finished, the blanking can be carried out in a manual mode, a blanking mechanism can be omitted, the butt-welding process is still automatically finished by equipment, so that the butt-welding yield of the terminal and the electrode plate is not influenced, the overall structure and the occupied area of the equipment can be further reduced, and the efficiency is relatively reduced.
The automatic butt-welding machine for the electrode plate and the terminal has the advantages that the automation of the fixed connection of the electrode plate and the terminal is realized, the butt-welding efficiency is high, the production cost is low, the large-scale batch production can be realized, in addition, due to the mechanized production, the errors caused by manual operation are avoided, and the yield of products is improved.
The present embodiment also provides a PTC thermistor production apparatus including the automatic spot-weld machine for electrode tabs and terminals as described above.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific/preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. For those skilled in the art to which the invention pertains, a plurality of alternatives or modifications can be made to the described embodiments without departing from the concept of the invention, and these alternatives or modifications should be considered as belonging to the protection scope of the invention.
