Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cell preparation, in particular to a gravity type carrier induction switch. Background Art

[0002] In the process of preparing photovoltaic cells, cleaning equipment is indispensable for cleaning the battery wafers. The specific process is as follows: the mechanical arm of the cleaning equipment transfers the flower basket carrier loaded with battery wafers from one liquid medicine tank to another for cleaning; however, in the actual production process, it often occurs that due to the incomplete positioning of the flower basket carrier, the mechanical arm cannot smoothly grasp the flower basket carrier. Therefore, a carrier induction switch needs to be installed on the mechanical arm to detect in real time whether the flower basket carrier is in place, so that the staff can adjust it in time.

[0003] However, during the cleaning process, the use environment of the flower basket carrier is filled with acid-base chemical liquids. Inevitably, the carrier induction switch in the prior art will come into contact with the acid-base chemical liquids, so that chemical crystals adhere to the surface of the carrier induction switch. The carrier induction switch in the prior art includes a housing and a T-shaped connecting rod passing through the housing, making the overall mass of the carrier induction switch relatively light. When too many chemical crystals accumulate on the surface of the carrier induction switch, it is easy to block the connection between the housing and the T-shaped connecting rod, and then the T-shaped connecting rod is prone to the situation that it cannot move up and down in the housing, resulting in the failure of the carrier induction switch to trigger, thus triggering the alarm of the mechanical arm and causing the cleaning equipment to stop running, affecting the operation rate of the cleaning equipment and the qualification rate of photovoltaic cells; and because chemical crystals adhere to the surface of the carrier induction switch, it is necessary to clean it once or twice every week, consuming manpower, material resources and time.

[0028] Next, with reference to the drawings and embodiments, the specific embodiments of the present utility model will be further described in detail. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0029] As Figures 1 to 6 shown, a gravity vehicle sensing switch provided by the present utility model is connected to one side surface of a robotic arm. The gravity vehicle sensing switch includes a housing 1, a connecting rod 2, an upper gravity block 3, a lower gravity block 4, a laser sensor 5, an upper protective cover 6, a lower protective cover 7, two protective sleeves and a controller. Ear seats 11 are connected to both the left and right sides of the housing 1. The housing 1 is detachably connected to one side surface of the robotic arm through the ear seats 11. A through hole 12 is provided through the housing 1 from top to bottom. The connecting rod 2 passes through the through hole 12 vertically. The upper gravity block 3 is detachably connected to the top of the connecting rod 2. The lower gravity block 4 is detachably connected to the bottom of the connecting rod 2. The laser sensor 5 is connected to the inner wall of the through hole 12. The two ends of the upper protective cover 6 are respectively detachably connected to the top of the housing 1 and the bottom of the upper gravity block 3. The two ends of the lower protective cover 7 are respectively detachably connected to the bottom of the housing 1 and the top of the lower gravity block 4. Protective sleeves are wrapped around the outer peripheries of the upper gravity block 3 and the lower gravity block 4. The laser sensor 5 is electrically connected to the controller.

[0030] Specifically, the shapes of the upper gravity block 3 and the lower gravity block 4 in the present utility model are not limited. However, when the vehicle sensing switch is installed, the upper gravity block 3 may be in contact with one side surface of the robotic arm. Therefore, the surface of the upper gravity block 3 in contact with one side surface of the robotic arm should be set as a flat surface.

[0031] In the present utility model, the upper gravity block 3 is threadedly connected to the top of the connecting rod 2, and the lower gravity block 4 is threadedly connected to the bottom of the connecting rod 2.

[0032] In a specific embodiment, when the robotic arm moves downward to prepare to grasp the flower basket carrier, if the connecting rod 2 moves upward within the through hole 12, the laser sensor 5 located within the through hole 12 detects the movement of the connecting rod 2 and transmits a signal to the controller. The controller can determine that the bottom of the lower gravity block 4 is in contact with the top surface of the flower basket carrier at this time, indicating that the flower basket carrier is in place. When the movement of the flower basket carrier is completed and the robotic arm moves upward to unload the flower basket carrier, due to the weight of the lower gravity block 4 and the upper gravity block 3, the connecting rod 2 moves downward within the through hole 12 to prepare for the next detection of whether the flower basket carrier is in place.

[0033] Under the action of the weights of the upper gravity block 3 and the lower gravity block 4, even if chemical crystals adhere to the surface of the housing 1 or within the through hole 12, it will not cause the connecting rod 2 to be unable to move up and down, avoiding the situation where the carrier induction switch cannot be triggered and the robotic arm alarms, reducing the possibility of the cleaning equipment stopping operation, and improving the operating rate of the cleaning equipment and the qualification rate of the photovoltaic cells.

[0034] By connecting the two ends of the upper protective cover 6 to the top of the housing 1 and the bottom of the upper gravity block 3 respectively, and connecting the two ends of the lower protective cover 7 to the bottom of the housing 1 and the top of the lower gravity block 4 respectively, and wrapping protective sleeves around the outer peripheries of the upper gravity block 3 and the lower gravity block 4, the top, bottom, connecting rod 2, upper gravity block 3, and lower gravity block 4 of the through hole 12 can be protected, avoiding the attachment of chemical crystals, reducing the cleaning frequency of the carrier induction switch, and reducing the consumption of manpower and time.

[0035] Furthermore, by setting both ends of the position where the through hole 12 is opened on the housing 1 as planes, it is convenient for the connection between the upper protective cover 6 and the lower protective cover 7 and the housing 1, and can also ensure the sealing performance of the connection between the upper protective cover 6 and the lower protective cover 7 and the housing 1.

[0036] Optionally, a gravity-type carrier induction switch further includes two sets of rolling groups 8, and the two sets of rolling groups 8 are respectively fixedly connected to both sides of the inner wall of the through hole 12; each set of rolling groups 8 includes a plurality of rollers 81, a plurality of support shafts 82, and a plurality of roller brackets 83. Each support shaft 82 passes through both sides of each roller 81, and each roller 81 is rotatably connected to each support shaft 82. One end of each roller bracket 83 is fixedly connected to both ends of each support shaft 82, and the other end of each roller bracket 83 is fixedly connected to one side of the inner wall of the through hole 12; the plurality of roller brackets 83 in each set of rolling groups 8 are spaced apart on the same side of the inner wall of the through hole 12; a rolling groove is circumferentially formed on the rolling surface of each roller 81, one side surface of the connecting rod 2 abuts against the bottom surface of the rolling groove, and the width of the rolling groove is greater than the width of the connecting rod 2.

[0037] When the connecting rod 2 moves up and down, the rollers 81 in the two sets of rolling groups 8 can assist in the movement, making the movement of the connecting rod 2 smoother.

[0038] Optionally, a gravity vehicle induction switch further includes a spring 9, the spring 9 is located between the lower protective cover 7 and the connecting rod 2, and the two ends of the spring 9 are respectively abutted against the bottom of the housing 1 and the bottom of the lower gravity block 4.

[0039] By arranging the spring 9, when the connecting rod 2 moves upward, the spring 9 is compressed, and when the connecting rod 2 moves downward, due to the restoring elastic force of the spring 9, an elastic force can be applied to the connecting rod 2, which is more beneficial to the falling and resetting of the connecting rod 2.

[0040] Optionally, the mass of the lower gravity block 4 is greater than the mass of the upper gravity block 3.

[0041] By increasing the mass of the lower gravity block 4, when the connecting rod 2 moves downward, the lower gravity block 4 provides a greater gravity for the connecting rod 2, so that the connecting rod 2 can break through the blockage of the chemical crystal and fall smoothly.

[0042] Optionally, both of the protective sleeves are made of PVDF material.

[0043] The protective sleeve made of PVDF material has good corrosion resistance and anti-aging performance. During the process of moving the movable flower basket carrier, it can protect the upper gravity block 3 and the lower gravity block 4 from being corroded by chemical drugs.

[0044] Optionally, both the upper protective cover 6 and the lower protective cover 7 are bellows-type protective covers.

[0045] Specifically, the outsides of the upper protective cover 6 and the lower protective cover 7 in the present utility model are both wrapped with nylon cloth, and the insides are both supported by PVC boards.

[0046] Both the upper protective cover 6 and the lower protective cover 7 are bellows-type protective covers, which can elongate or shorten as the connecting rod 2 moves up and down to ensure the sealing and protection effect on the connecting rod 2.

[0047] In summary, for the gravity - induced vehicle switch provided by the present utility model, by setting the upper gravity block 3 and the lower gravity block 4, the connecting rod 2 can move up and down in the through - hole 12 regardless of whether there is chemical crystal attachment, avoiding the situation of triggering the robotic arm alarm, reducing the possibility of the cleaning equipment stopping operation, and improving the operating rate of the cleaning equipment and the qualification rate of the photovoltaic cells; by setting the upper protective cover 6, the lower protective cover 7 and two protective sleeves, it can ensure that the connecting rod 2, the upper gravity block 3 and the lower gravity block 4 are not attached by chemical crystals and are not corroded by chemical drugs, reducing the cleaning frequency of the chemical crystals attached to the present utility model; by setting two sets of rolling groups 8, it can make the connecting rod 2 move more smoothly up and down in the through - hole 12; by setting the spring 9, it can provide elastic force for the connecting rod 2, which is more conducive to the falling and resetting of the connecting rod 2.

[0048] The above - mentioned is only the preferred embodiment of the present utility model and is not used to limit the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
