Description

Technical Field

[0001] The invention belongs to the technical field of industrial manufacturing equipment, and in particular relates to an automatic feeding device for filter screen assembly. Background Art

[0002] In the production and assembly process of fully automatic washing machines, the water inlet filter is an important component that filters impurities in the incoming water and protects the internal parts of the washing machine. The water inlet filter is generally composed of a stainless steel filter body and a plastic frame that fixes the filter through injection molding. In the process of manufacturing the water inlet filter on an automated production line, the stainless steel filter body first needs to be accurately placed on the jig of the feeding equipment, and then the stainless steel filter body is transported one by one to the injection molding machine through the automated feeding device for injection molding of the frame.

[0003] However, in the production process of the water inlet filter, due to the overall thin thickness of the stainless steel filter body, deformation problems such as bending, creases or warping may occur during the manufacturing, transportation and placement on the loading fixture. When the deformation degree of the stainless steel filter body exceeds the allowable range, these deformations will affect the combination of the filter and the frame, resulting in the overlap width of the filter and the frame (that is, the width of the overlapping part of the filter and the frame is insufficient), causing the filter and the frame to be poorly locked, thereby reducing the yield rate and service life of the product.

[0004] In the prior art, when placing the stainless steel filter body inside the feeding fixture, in order to avoid the phenomenon of poor locking of the stainless steel filter and the frame, it is mostly necessary to check the flatness of the stainless steel filter by manual inspection or visual inspection system. However, the above two inspection methods still have the following problems in actual application:

[0005] 1. When the degree of bending is close to the upper limit of the allowable range, it is difficult to distinguish by human eyes (for example, the allowable range of the height difference of the bending part of the stainless steel filter body is 0-3mm. When the height difference of the bending part of the stainless steel filter body is 4mm, it is difficult to distinguish manually), which leads to missed detection or misdetection. In addition, long-term manual inspection is prone to inattention and visual fatigue, and it is difficult to completely eliminate the stainless steel filter body with unqualified flatness, which ultimately makes it difficult to further improve the yield rate of the water inlet filter for a long time;

[0006] 2. When the stainless steel filter body with qualified flatness is placed inside the jig manually, if the stainless steel filter body cannot be aligned with the storage position inside the jig, the stainless steel filter body will touch the outer wall of the jig first. In this process, there is a certain probability that the flat stainless steel filter body will be slightly bent (for example, during the placement process, the feeding force or speed when inserting the stainless steel filter body into the jig is large), and in the actual production process, the bending of the stainless steel filter body caused by this phenomenon is often not detected in time;

[0007] 3. Although the introduction of the visual inspection system has improved the level of quality control, it has also significantly increased equipment investment, operating costs and maintenance costs.

[0008] In view of the above problems, there is an urgent need for an automatic feeding device for filter assembly that is cost-effective, can avoid deformation caused by manual operation, and does not require an expensive visual inspection system. This device will provide a solution to ensure the flatness of the filter body, reduce deformation caused by manual operation, improve assembly efficiency and product yield, control production costs, and improve the manufacturing quality of the water inlet filter of fully automatic washing machines.

The housing 102 has a positioning cavity 103 formed inside the housing 102, and reset cavities 104 are formed inside the housing 102 and on both sides of the positioning cavity 103. A conductive ejector pin 105 is fixed at one end of each of the two reset cavities 104, and one end of the conductive ejector pin 105 passes through the reset cavity 104 and extends to the outside of the reset cavity 104. A warning element 106 is fixed at the upper end of the housing 102, and guide bars 107 are fixed at both sides of the positioning cavity 103. The cross-sectional shape of the guide bar 107 is L-shaped, and a guide surface 108 is obliquely formed at one end of the guide bar 107 away from the warning element 106. The filter body entering the positioning cavity 103 can be guided and positioned by the two guide bars 107.

[0068] A plurality of detection parts 200, wherein the plurality of detection parts 200 are assembled on both sides of the interior of the positioning cavity 103, the detection part 200 comprises a plurality of guide rods 201, a plurality of conductive pillars 202, and two wiring sleeves 203, the guide rods 201 are slidably connected to the interior of the housing 102 and are located in the side wall of the positioning cavity 103, a rotation-stopping surface is arranged on the outer side of the guide rods 201, a chamfered surface is arranged inside the positioning cavity 103, and the rotation-stopping surface and the chamfered surface are matched, the plurality of conductive pillars 202 are respectively fixed to one side of the plurality of guide rods 201 and are located inside the positioning cavity 103, and two adjacent conductive pillars 202 located inside the same detection part 200 are slidably connected, the two wiring sleeves 203 are respectively fixed to the upper end and the lower end inside the reset cavity 104, and the guide rod 201 located at the uppermost end and the guide rod 201 located at the lowermost end are respectively slidably connected to the two wiring sleeves 203;

[0069] A plurality of reset parts 300, wherein the plurality of reset parts 300 are respectively assembled inside the plurality of reset cavities 104, and the plurality of reset parts 300 and the plurality of reset cavities 104 correspond one to one;

[0070] The reset driving part 400 is assembled on the upper end of the fixture body 101, and the reset driving part 400 is adapted to the reset part 300;

[0071] Among them, multiple detection parts 200, two conductive pins 105 and warning elements 106 located inside the same shell 102 are connected in series through wires to form a detection circuit. In the initial state, the detection part 200 is in a closed state. When the uneven filter body is inserted into the positioning cavity 103, any two adjacent guide rods 201 are away from each other, and the detection part 200 and its corresponding detection circuit are changed from a connected state to an open state.

[0072] It should be noted that a positioning boss is provided at the upper end of the loading workbench 100, a power supply male head is provided inside the positioning boss, a power supply female head is provided at one end of the fixture body 101, the power supply female head and the power supply male head are adapted to each other, a plurality of conductive contacts 109 are provided inside the fixture body 101, and the power supply female head and the plurality of conductive contacts 109 are electrically connected in parallel through wires, and the plurality of conductive contacts 109 and the plurality of conductive ejector pins 105 are adapted one by one.

[0073] Furthermore, when the flatness of the filter body is detected by the detection circuit, the voltage and current values ​​connected to the detection circuit are within the safe range and will not cause personal injury to the staff. At the same time, in order to further improve safety, the staff can also place the filter body inside the fixture body 101 by wearing insulating gloves. Of course, other methods can also be used to improve the personal safety of the staff, which are not listed here one by one.

[0074] Furthermore, in the present embodiment, the end surfaces of the two guide bars 107 located inside the same shell 102 that are close to each other are recorded as limit surfaces, the distance between the two limit surfaces is recorded as L1, the thickness of the filter body is recorded as L2, L1=L2+L3, L3 is the gap value, and the gap value range is 0 to 3 mm. In the present embodiment, the gap value L3 is 3 mm. In the initial state, when the flat filter body enters the positioning cavity 103 under the guidance of the guide bar 107, the filter body will not touch the conductive column 202. Only when the filter body is bent and the height difference of the bent part is greater than or equal to 3 mm, the bent filter body will touch the conductive column 202 and cause the detection circuit to change from the on state to the off state.

[0075] It should be noted that, for washing machines of different brands, models and production processes, during the production process of the water inlet filter, the acceptable range of the bending degree of the filter body varies, and the value range of the gap value L3 also varies, which does not constitute a specific limitation here.

[0076] Here, the warning method of the warning element 106 includes but is not limited to light warning and sound warning. In the present embodiment, the warning method of the warning element 106 is preferably light warning. Specifically, when the power supply male connector and the power supply female connector are connected and the detection unit 200 is in a circuit state, the warning element 106 can emit light. When the power supply male connector and the power supply female connector are disconnected from each other or the detection unit 200 is in a circuit-breaking state, the warning element 106 is in a closed state.

[0077] Specifically, a lifting belt module, a first belt module and a second belt module are provided inside the double-layer belt module 110. The first belt module is located at the upper end of the second belt module, and the lifting belt module is located at one end of the first belt module and the second belt module. The lifting belt module can drive the jig body 101 to move between the first belt module and the second belt module. When producing the water inlet filter screen product, the jig body 101 loaded with the filter screen body is placed on the first belt module, and the jig body 101 is driven to move by the first belt module, and the filter screen bodies are taken out one by one by the material taking module 120. After the filter screen body is taken out, the jig body 101 is transported to the upper end of the lifting belt module by the first belt module, and the jig body 101 is transported to the second belt module by the lifting belt module. The double-layer belt module 110 is an existing mature application, and its specific working principle will not be further described here.

[0078] In this embodiment, the jig body 101 on which the filter body is to be placed is placed on the upper end of the loading workbench 100, and the power supply male head on the loading workbench 100 is connected to the power supply female head on the jig body 101, and a closed circuit is formed between the power supply male head, the power supply female head, the conductive contact sheet 109 and the detection circuit. The operator inserts the filter body into the plurality of positioning cavities 103 one by one. When the filter body is creased, bent or warped during transportation or insertion, resulting in an uneven surface of the filter body, the uneven filter body will touch the conductive column 202 during the insertion process of the uneven filter body into the positioning cavity 103, and drive the conductive column 202 that contacts to touch. Movement occurs. When the moving conductive column 202 is separated from the adjacent conductive column 202, the corresponding detection circuit and the detection unit 200 are changed from the on state to the off state. The operator can judge that the corresponding filter body is uneven and needs to be removed by whether the warning element 106 emits light. When the filter body is placed inside the jig body 101 and all the warning elements 106 can emit light, the filter body is placed inside the double-layer belt module 110. The jig body 101 carrying the filter body is transported to the designated position by the double-layer belt module 110 so that the material taking module 120 can take out the filter bodies one by one and perform subsequent frame injection molding.

[0079] It should be noted that in this embodiment, the detection parts 200 are all arranged in a vertical direction. In order to improve the accuracy of flatness detection, the detection parts 200 can also be placed horizontally or tilted. The specific placement direction can be adjusted according to usage requirements, which does not constitute a specific limitation here.

[0080] Next, please refer to Figure 8 and Fig. 9 As shown, a connecting column 204 is integrally formed at the upper end of the conductive column 202 , a conductive groove 205 is opened at the lower end inside the conductive column 202 , and two adjacent conductive columns 202 are slidably connected through the cooperation of the connecting column 204 and the conductive groove 205 .

[0081] It should be noted that the uppermost conductive pillar 202 is not provided with a connecting pillar 204 .

[0082] Furthermore, a protective sleeve 206 is sleeved on the outer side of the conductive pillar 202 , and the material of the protective sleeve 206 is an insulating material.

[0083] In this embodiment, the provision of the protective sleeve 206 can prevent the stainless steel filter body from having a wire phenomenon, thereby causing the corresponding warning element 106 to remain in a luminous state after the detection unit 200 changes from a circuit state to a circuit-breaking state.

[0084] Next, please refer to Fig.10The reset portion 300 includes two first guide pillars 301, a reset plate 302 and a transmission rod 303. The two first guide pillars 301 are respectively fixed at the two ends inside the reset cavity 104. The reset plate 302 is slidably connected to the outer sides of the two first guide pillars 301. The upper and lower ends of the reset plate 302 are inclined to open a reset driving surface 304, and the reset driving surface 304 is adapted to the guide rod 201. The transmission rod 303 is fixed to the upper end of the reset plate 302.

[0085] Furthermore, a linkage pile head 305 is integrally formed at the upper end of the transmission rod 303 . The cross-sectional shape of the linkage pile head 305 in the vertical direction is an I-shape, and the linkage pile head 305 is matched with the reset driving part 400 .

[0086] Furthermore, the reset plate 302 is made of insulating material.

[0087] In this embodiment, when the uneven filter body drives the conductive column 202 to move, so that the detection circuit and the detection unit 200 are changed from the open state to the open state, the uneven filter body is taken out from the positioning cavity 103 and removed, and the reset drive unit 400 is operated to operate, and the linkage pile head 305 is driven to move upward by the reset drive unit 400. Through the fixed connection between the linkage pile head 305 and the transmission rod 303 and the fixed connection between the transmission rod 303 and the reset plate 302, the reset drive unit 400 drives the reset plate 302 and the transmission rod 303 to move upward synchronously. When the reset drive surface 304 contacts the displaced conductive column 202, the conductive column 202 is driven to move and reset by the reset drive surface 304, thereby restoring the detection circuit and the detection unit 200 in the open state to the open state, so as to detect the flatness of the subsequent filter body.

[0088] Please refer again Fig.11 As shown, the reset drive unit 400 includes two second guide pillars 401, a cross beam 402, a plurality of cross bars 403 and a plurality of clamping plates 404. The two second guide pillars 401 are respectively slidably connected to the two sides inside the fixture body 101, the cross beam 402 is fixed between the two second guide pillars 401, a handle is fixed to the upper end of the cross beam 402, and an anti-slip sleeve is sleeved on the outer side of the handle. The plurality of cross bars 403 are all fixed to one end of the cross beam 402 close to the shell 102, and the plurality of clamping plates 404 are respectively slidably connected to one end of the plurality of cross bars 403 away from the cross beam 402, and the clamping plates 404 are adapted to the linkage pile heads 305.

[0089] In this embodiment, when the uneven filter body causes the detection circuit and the detection part 200 to change from the passage state to the disconnection state, the handle is held and the cross beam 402 is driven to move upward by the handle. The cross beam 402 and the cross bar 403 are fixedly connected and the cross bar 403 and the card plate 404 are slidably connected, so that the cross beam 402 drives the cross bar 403 and the card plate 404 to move synchronously. Since the card plate 404 and the linkage pile head 305 are adapted to each other, the linkage pile head 305 is driven to move by the card plate 404, thereby causing the reset part 300 to operate. The reset part 300 drives the detection circuit and the detection part 200 to change from the disconnection state to the passage state. After the detection circuit and the detection part 200 are restored to the passage state, the cross beam 402 is moved downward by the handle so that the cross bar 403, the card plate 404 and the reset part 300 are restored to the initial state.

[0090] Please refer again Fig.12 A linkage rod 405 is fixed to one end of the card plate 404 close to the cross bar 403, and one end of the linkage rod 405 extends to the inside of the cross bar 403. An elastic element 406 is installed between the linkage rod 405 and the cross bar 403, and the cross bar 403 and the card plate 404 are slidably connected through the linkage rod 405.

[0096] The working principle of the present invention is:

[0097] Place the fixture body 101 on which the filter body is to be placed on the upper end of the loading workbench 100, and make the power supply male and female heads electrically connected. The operator inserts the filter bodies into the multiple positioning cavities 103 one by one. During the insertion of the uneven filter body into the positioning cavity 103, the uneven filter part will touch the conductive column 202 and drive the conductive column 202 to move. After the two adjacent conductive columns 202 are separated from each other, the corresponding detection circuit and the detection unit 200 are changed from the on state to the off state. The operator can judge whether the corresponding filter body is uneven and needs to be repaired by whether the warning element 106 emits light. After the uneven filter is removed, pull the handle to drive the reset plate 302, the transmission rod 303 and the linkage pile head 305 to move upward synchronously through the clamping plate 404, and drive the moving conductive column 202 to reset through the reset plate 302, so as to facilitate subsequent detection. After the filter body is placed inside the jig body 101, and all the warning elements 106 can emit lights, the filter body is placed inside the double-layer belt module 110, and the jig body 101 carrying the filter body is transported to the designated position by the double-layer belt module 110, so that the material taking module 120 can take out the filter bodies one by one and perform subsequent frame injection molding.
