[0027] The utility model will be further described in detail in combination with specific embodiments, but the implementation mode of the utility model is not limited to this.

[0028] Referring to Figure 1 and Figure 2 , the utility model provides a kind of air-drying post-discharge device for PTC ceramic heating sheet, it includes link channel 100, arc baffle 200 and downhill passage 300.

[0029] The link channel 100 is connected with the end of previous process air-drying unit passage 800, and the surface roughness Ra of the surface of the link channel 100 passage is ≤0.5 μm.

[0030] The arc-shaped baffle 200 is arranged in the connecting channel 100 and connects with the air-drying unit channel 800 in a tangential connection mode, and the arc-shaped baffle 200 converts the PTC ceramic heating sheet a from a vertical posture to a horizontal posture by contacting the PTC ceramic heating sheet a output from the air-drying unit channel 800 and turns back into the downhill channel 300. The surface roughness Ra of the part of the arc-shaped baffle 200 contacting the PTC ceramic heating sheet a is less than or equal to 0.5 microns.

[0031] The top end of the downhill channel 300 connects with the outlet end of the connecting channel 100, and the bottom end connects with the subsequent feeding channel 900, so as to guide the PTC ceramic heating sheet a entering the downhill channel 300 into the feeding channel 900. The surface roughness Ra of the upper surface of the downhill channel 300 is less than or equal to 0.5 microns.

[0032] Wherein, referring to Figure 1 , the connecting channel 100 is formed by connecting the L-shaped structure block 1a with the end of the air-drying unit channel 800. The arc-shaped baffle 200 is arranged at the corner inside the L-shaped structure block 1a.

[0033] It should be noted that the PTC ceramic heating sheet a in the patent has a structure as shown in Figure 4 , which is a sheet-shaped cubic structure with a certain thickness and large upper surface a2 and lower surface area. Therefore, the vertical posture mentioned above refers to the posture when the thickness surface a1 (specifically, the thickness surface in the length direction) of the PTC ceramic heating sheet a serves as a support surface (see the partial enlarged view in Figure 1 ), and the horizontal posture refers to the posture when the large upper surface a2 or lower surface of the PTC ceramic heating sheet a serves as a support surface (see the PTC ceramic heating sheet a on the downhill channel 300 in Figure 1 ).

[0034] Wherein, the width of the air-drying unit channel 800 is relatively narrow, and the PTC ceramic heating sheet a passes through the air-drying unit channel 800 in a vertical posture. The air-drying unit channel 800 is used for air-drying the PTC ceramic heating sheet a which has completed surface cleaning (using high-pressure water washing).

[0035] The working principle of the air-drying and discharging device is as follows:

[0036] When the PTC ceramic heating sheet a is output from the end of the air-drying unit passage 800 in a vertical posture, after leaving the air-drying unit passage 800, the PTC ceramic heating sheet a will contact the arc-shaped baffle 200. At the time of contact, the arc-shaped baffle 200 will force the PTC ceramic heating sheet a to change from a vertical posture to a horizontal posture, and then simultaneously turn to enter the subsequent downhill passage 300, and then slide into the feeding passage 900, and be sent to the subsequent work station by the feeding passage 900, and wait for the mechanical hand to stack it on the copper disc.

[0037] Since the surface roughness Ra of the part in contact with the PTC ceramic heating sheet a is ≤0.5 μm, a high smoothness is ensured, and scratches on the surface of the PTC ceramic heating sheet a can be avoided when in contact.

[0038] The design of the arc-shaped baffle 200 can make the turning and the change from a vertical posture to a horizontal posture of the PTC ceramic heating sheet a more smooth, and avoid collision and scratches as much as possible.

[0039] In a preferred embodiment, the upper surface of the downhill passage 300 uses a mirror surface stainless steel plate as the supporting plate 310 in contact with the PTC ceramic heating sheet a.

[0040] The supporting plate 310 is detachably installed on the upper surface of the downhill passage 300, for example, the supporting plate 310 is installed on the upper surface of the downhill passage 300 by clamping and covering. The supporting plate 310 is designed to be detachable, which is beneficial to replacement after long-term use.

[0041] Referring to Figure 1 and Figure 2 , the end of the downhill passage 300 is lapped on the two limiting baffle strips 910 on both sides of the feeding passage 900. The end of the supporting plate 310 extends and is lapped on the feeding conveyor belt 920 between the two limiting baffle strips 910.

[0042] The end of the supporting plate 310 extends and is lapped on the feeding conveyor belt 920, which can extend the guide passage, reduce the falling height of the PTC ceramic heating sheet a, and avoid collision and damage of the PTC ceramic heating sheet a.

[0043] In addition, the end of the supporting plate 310 has the freedom of up and down movement, and can be raised upward when subjected to an upward force.

[0044] The end of the supporting plate 310 can be raised upward, and the purpose is that in actual application, a plurality of grinding machines (used for grinding the PTC ceramic heating sheet formed by pressing) will correspond to one full-automatic disc stacking machine, so there will be a plurality of air-drying and discharging devices, and the PTC ceramic heating sheet a discharged by each air-drying and discharging device will enter the feeding passage 900 (see Figure 3), while the number of feeding channels 900 is fixed (for example Figure 1 As shown, there are two, so there can be a case where one PTC ceramic heating sheet a is discharged from one air-drying and discharging device and passes under the other air-drying and discharging device; for this reason, in the utility model, the end of the supporting plate 310 is designed to have a certain degree of freedom and can be raised upward, when a PTC ceramic heating sheet a passes under the supporting plate 310, the PTC ceramic heating sheet a can push the end of the supporting plate 310 upward, so that the end of the supporting plate 310 is raised upward, thereby ensuring that the PTC ceramic heating sheet a can pass smoothly under the supporting plate 310, see the partial enlarged view in Figure 3 .

[0045] Preferably, the surface roughness Ra of the upper surface of the supporting plate 310 is 0.4 μm, so as to reduce the abrasion and scratches on the PTC ceramic heating sheet a as much as possible.

[0046] In a preferred embodiment, the top end of the downhill channel 300 is connected to the outlet end of the connecting channel 100 by magnetic attraction, and the end of the downhill channel 300 can be switched to connect to different feeding channels 900 based on the magnetic attraction. The different feeding channels 900 are arranged side by side and parallel to each other, see Figure 1 .

[0047] Based on the above-mentioned magnetic attraction, the worker can change lanes for the downhill channel 300 more conveniently, that is, during operation, the end of the downhill channel 300 can be connected to a certain feeding channel 900 according to the situation.

[0048] In a preferred embodiment, the arc-shaped baffle 200 is bent from a mirror stainless steel plate, and the surface roughness Ra of the part of the arc-shaped baffle 200 that contacts the PTC ceramic heating sheet a is 0.4 μm, so as to reduce the abrasion and scratches on the PTC ceramic heating sheet a as much as possible.

[0049] In a preferred embodiment, the air-drying and discharging device of the utility model further comprises a turning protrusion 400. As shown in Figure 1 , the turning protrusion 400 is arranged at the end of the air-drying unit channel 800 and is used to assist the PTC ceramic heating sheet a to turn into the downhill channel 300.

[0050] The above only describes the preferred embodiments of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
