[0002] As an electronic component, switches are widely used in life. Wall switches are electrical switches installed on the wall to connect and disconnect circuits and control lighting. With the improvement of people's quality of life, wall switches are no longer limited to connecting and disconnecting circuits, but also have home decoration functions.

[0003] The wall switch includes a cover plate. Since the cover plate is exposed to the air, the cover plate will be sprayed during the production process to improve the durability and aesthetics of the cover plate. The existing spraying method is usually to set a number of jigs on a circulating spraying conveyor belt. The cover plate is fixed on the jig and moves with the circulating spraying conveyor belt. The spraying equipment on the spraying line sprays the switch cover plate while the jig moves. The specific structure of the jig is shown in the attached figure. Figure 13 As shown, the fixture includes two elastic sheets, a horizontal sheet and a connecting rod. The lower ends of the two elastic sheets are fixed on the horizontal sheet, and the upper ends are stretched to both sides to support and fix the lower edge of the cover plate. The connecting rod is located below the horizontal sheet, the upper end of the connecting rod is fixedly connected to the horizontal sheet, and the lower end is fixed on the spray conveyor belt.

[0004] Before spraying, the switch cover plate needs to be loaded onto various jigs. After spraying, the switch cover plate needs to be unloaded from various jigs. In the existing spraying assembly line, manual loading and unloading of the switch cover plate is adopted, which has high labor cost and low loading and unloading efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a loading and unloading device for spraying switch cover plates, which can be used for batch loading and unloading of switch cover plates with high loading and unloading efficiency.

[0006] To achieve the above object, the present invention provides the following technical solution: a loading and unloading device for spraying switch cover plates, comprising a loading mechanism and a unloading mechanism, wherein the loading mechanism and the unloading mechanism are both arranged on one side of a spraying conveyor belt;

[0007] The feeding mechanism includes a first mounting frame, a first moving assembly, a first matching assembly and a conveying assembly, wherein the conveying assembly is arranged on the first mounting frame, and a plurality of conveying assemblies are arranged, and the plurality of conveying assemblies are spaced apart along the conveying direction of the spraying transmission belt, and the conveying assembly is used to convey the accumulated switch cover plates one by one to the first moving area in sequence;

[0008] The first moving component is fixed on the first mounting bracket, and the first moving component is used to move the switch cover plate in the first moving area to the jig.

[0009] The first matching component is fixed on the first moving component. A plurality of the first matching components are provided, and the plurality of first matching components are spaced apart along the conveying direction of the spraying conveyor belt. The first matching component is used to squeeze the elastic pieces on the jig when the switch cover plate moves to the jig, so that the two elastic pieces bend inward.

[0010] The blanking mechanism includes a second mounting bracket, a second moving component, a second matching component, and a blanking conveyor component. The second moving component is fixed on the second mounting bracket, and the second moving component is used to move the switch cover plate on the jig to the blanking conveyor component.

[0011] The second matching component is fixed on the second moving component. A plurality of the second matching components are provided, and the plurality of second matching components are spaced apart along the conveying direction of the spraying conveyor belt. The second matching component is used to squeeze the elastic pieces on the jig when the switch cover plate is removed from the jig, so that the two elastic pieces bend inward.

[0012] The blanking conveyor component is fixed on the second mounting bracket, and the blanking conveyor component is used to receive and convey the switch cover plate.

[0013] As a further improvement of the present invention, the conveying component includes a conveying frame, a conveyor belt, a conveying driving member, and a stacking frame. The conveying frame is installed on the mounting bracket, the conveyor belt is installed on the conveying frame, the conveying driving member is installed on the conveying frame, and the conveying driving member is used to drive the conveyor belt to work. The conveying frame includes a baffle, and the baffle is located at the end of the conveying direction of the conveyor belt. The baffle is used to block the switch cover plate from moving out of the conveyor belt along the conveying direction. The stacking frame is fixed on the conveying frame, and the stacking frame is located at the starting end of the conveying direction of the conveyor belt. An accommodation cavity is formed between the side wall of the stacking frame and the conveyor belt. The accommodation cavity is used to accommodate the stacked switch cover plates. The cross-section of the accommodation cavity is adapted to the cross-section of the switch cover plate. A conveying gap is formed between the side wall of the stacking frame and the conveyor belt. The height of the conveying gap is greater than the height of one switch cover plate and less than the height of two switch cover plates. The conveying gap is used to allow the switch cover plate to move out of the accommodation cavity along the conveying direction of the conveyor belt.

[0014] With such a setting, the conveying driving member drives the conveyor belt to work. During the operation of the conveyor belt, the lowermost switch cover plate in the stacked switch cover plates is driven out of the conveying gap by friction and finally conveyed to the position where the switch cover plate abuts against the baffle. This position is the position for the moving assembly to pick up the switch cover plate. Whenever a switch cover plate is driven out of the conveying gap, the conveyor belt will convey the next switch cover plate. This conveying assembly realizes the one-by-one conveying of the switch cover plates and has strong practicability.

[0015] As a further improvement of the present invention, a separating column is provided on the conveying frame. A plurality of conveyor belts are provided, and the plurality of conveyor belts are arranged in parallel. The separating column is provided between adjacent conveyor belts. The separating column is fixed to the conveying frame, and the stacking frames are arranged in one-to-one correspondence with the conveyor belts.

[0016] With such a setting, each conveying assembly can synchronously convey the switch cover plates in multiple stacked frames, improving the conveying efficiency of the switch cover plates.

[0017] As a further improvement of the present invention, a position sensor is fixed on the baffle. The position sensor is used to detect whether the switch cover plate is conveyed to the set position.

[0018] With such a setting, the position sensor is used to detect whether the switch cover plate is conveyed in place. After being conveyed to the designated position, the moving assembly starts to work.

The first Z-direction driving sub-assembly is used to drive the first Z-direction moving platform to slide;

[0023] The first induction sensor is arranged on the first X-direction moving platform. The first induction sensor is used to detect the passing of the jig;

[0024] The second moving assembly includes a second induction sensor, a second X-direction moving platform, a second Y-direction moving platform, a second Z-direction moving platform and a plurality of second adsorption sub-assemblies. The X-direction, Y-direction and Z-direction are mutually perpendicular directions. The X-direction is the conveying direction of the jig and the opposite direction of the conveying direction. The Z-direction is the vertical direction;

[0025] The second X-direction moving platform is slidably connected to the second mounting bracket, and the sliding direction is the X-direction. The second Y-direction moving platform is slidably connected to the second X-direction moving platform, and the sliding direction is the Y-direction. The second Z-direction moving platform is slidably connected to the second Y-direction moving platform, and the sliding direction is the Z-direction;

[0026] The second adsorption sub-assembly is fixed on the second Z-direction moving platform. A plurality of the second adsorption sub-assemblies are distributed at intervals in the X-direction. The distance between adjacent second adsorption sub-assemblies is the same as the distance between adjacent jigs. The second adsorption sub-assembly includes a second air nozzle. The second air nozzle is connected to a gas supply source. The second air nozzle is used to adsorb the switch cover;

[0027] A second X-direction driving sub-assembly is installed on the second mounting bracket. The second X-direction driving sub-assembly is used to drive the second X-direction moving platform to slide. A second Y-direction driving sub-assembly is installed on the second X-direction moving platform.

A second Z-direction driving sub-assembly is installed on the second Y-direction moving platform. The second Z-direction driving sub-assembly is used to drive the second Z-direction moving platform to slide;

[0028] The second induction sensor is arranged on the second X-direction moving platform. The second induction sensor is used to detect the passing of the jig.

[0029] By such an arrangement, the first moving assembly can synchronously adsorb the switch covers at each set position through the first adsorption sub-assembly. After the first induction sensor senses the jig, the first moving assembly drives the switch cover to move in the X-direction, Y-direction and Z-direction, and finally moves the switch cover onto the jig.

[0030] After the second induction sensor senses the fixture, each second adsorption sub-assembly moves above each fixture. The second moving assembly can synchronously adsorb each switch cover plate through the second adsorption sub-assembly and can drive the switch cover plate to move in the X, Y, and Z directions, and finally move the switch cover plate on the fixture to the blanking conveyor assembly.

[0031] As a further improvement of the present invention, the first induction sensor is arranged on one side of the first Y-direction moving table. When the fixture is conveyed, it sequentially passes in front of the first induction sensor and the first adsorption sub-assembly. The first induction sensor is also used to count the fixtures passing through.

[0032] The second induction sensor is arranged on one side of the second Y-direction moving table. When the fixture is conveyed, it sequentially passes in front of the second induction sensor and the second adsorption sub-assembly. The second induction sensor is also used to count the fixtures passing through.

[0033] By setting like this, the first induction sensor counts the fixtures. When the number of fixtures passing through the first induction sensor is equal to or greater than the number of adsorption sub-assemblies, each first adsorption sub-assembly synchronously drives each switch cover plate to be placed on each fixture.

[0034] The second induction sensor counts the fixtures. When the number of fixtures passing through the second induction sensor is equal to or greater than the number of adsorption sub-assemblies, each adsorption sub-assembly synchronously moves the switch cover plate on each fixture to the blanking conveyor assembly.

[0035] As a further improvement of the present invention, the first matching assembly is arranged in one-to-one correspondence with the first adsorption sub-assembly. The first matching assembly includes a first clamping rod, a first limiting block, and a first linear motion output member. There are two first clamping rods. The first clamping rods are slidably connected to the first Y-direction moving table, and the sliding direction is the X direction. The first linear motion output member is fixed on the first clamping rod. The first linear motion output member is used to drive the two first clamping rods to approach or separate from each other. The first limiting block is fixed on the first Y-direction moving table. There are two first limiting blocks. The first limiting blocks are used to limit the first clamping rods so that the two first clamping rods slide between the two first limiting blocks. When the first linear motion output member drives the two first clamping rods to approach each other, the first clamping rods clamp and drive the elastic sheet on the fixture to deform;

[0036] The second mating component is arranged in one-to-one correspondence with the second adsorption sub-component. The second mating component includes a second clamping rod, a second limiting block, and a second linear motion output member. There are two second clamping rods, which are slidably connected to the second Y-direction moving table in the X-direction. The second linear motion output member is fixed to the second clamping rod and is used to drive the two second clamping rods to approach or separate from each other. The second limiting block is fixed to the second Y-direction moving table. There are two second limiting blocks, which are used to limit the second clamping rod so that the two second clamping rods slide between the two second limiting blocks. When the second linear motion output member drives the two second clamping rods to approach each other, the second clamping rod clamps and deforms the elastic sheet on the fixture.

[0037] With such an arrangement, when the first Y-direction moving table moves along the Y-direction so that the two first clamping rods are respectively located on both sides of the fixture, the first linear motion output member drives the first clamping rods to approach each other, and the two first clamping rods will press the two elastic sheets on the fixture, so that the elastic sheets are deformed, facilitating the elastic sheets to enter the cavity of the switch cover when the switch cover is placed on the fixture.

[0038] When the second Y-direction moving table moves along the Y-direction so that the two second clamping rods are respectively located on both sides of the fixture, the second linear motion output member drives the second clamping rods to approach each other, and the two second clamping rods will press the two elastic sheets on the fixture, so that the elastic sheets are deformed, facilitating the elastic sheets to no longer have a spreading force on the switch cover when the switch cover is removed from the fixture, so that the switch cover can be smoothly separated from the fixture.

[0039] As a further improvement of the present invention, the first linear motion output member is a cylinder, the cylinder is installed on one of the first clamping rods, the output shaft of the cylinder is fixed to the other first clamping rod, and the axial direction of the output shaft of the cylinder is the X-direction;

[0040] The second linear motion output member is a cylinder, the cylinder is installed on one of the second clamping rods, the output shaft of the cylinder is fixed to the other second clamping rod, and the axial direction of the output shaft of the cylinder is the X-direction.

[0041] With such an arrangement, the cylinder realizes driving the two first clamping rods to approach or separate from each other, and the cylinder realizes driving the two second clamping rods to approach or separate from each other. The structure is simple and the practicability is strong.

[0042] As a further improvement of the present invention, the blanking conveyor component includes a blanking conveyor belt and a blanking driving member. The blanking conveyor belt and the blanking driving member are both installed on the second mounting bracket, and the blanking driving member is used to drive the blanking conveyor belt to move.

[0043] With such a setting, the blanking driving member drives the blanking conveyor belt to work. When a switch cover plate is placed on the blanking conveyor belt, the blanking conveyor belt will drive the switch cover plate to be conveyed, so that the switch cover plate after spraying can be conveyed out.

[0044] As a further improvement of the present invention, the blanking conveyor belt is located on the side of the mounting rack facing the spraying conveyor belt. The length direction of the blanking conveyor belt is consistent with the conveying direction of the spraying conveyor belt. Limit plates are provided on both sides in the length direction of the spraying conveyor belt. The limit plates are used to limit the switch cover plate, and the distance between the limit plates is adapted to the width of the switch cover plate.

[0045] With such a setting, the setting of the limit plates can prevent the switch cover plate from falling from both sides of the blanking conveyor belt. The distance between the limit plates being adapted to the width of the switch cover plate can make the conveying of the switch cover plate more orderly.

[0046] Beneficial effects of the present invention: Multiple conveying components convey each stack of stacked switch cover plates to the designated positions one by one. Then, the first moving component on the loading mechanism takes each switch cover plate from each designated position and places it on the fixture. During the placement process, the first matching component squeezes the elastic pieces on the fixture, so that the two elastic pieces can enter the cavity of the switch cover plate. When the first matching component no longer squeezes the elastic pieces, the two elastic pieces expand outwards, thereby clamping the side wall of the cavity of the switch cover plate, thus realizing the fixation between the switch cover plate and the fixture. After the switch cover plate follows the fixture through the spraying equipment on the spraying production line for spraying, it enters the blanking mechanism. The second moving component on the blanking mechanism takes down several switch cover plates from each fixture at one time and moves them to the blanking conveying component. During the process of taking down the switch cover plate, the second matching component squeezes the elastic pieces on the fixture, so that the elastic pieces and the switch cover plate can be smoothly separated. After receiving the switch cover plate, the blanking conveying component conveys the switch cover plate out. Therefore, through the settings of the loading mechanism and the blanking mechanism, the device can be used for batch loading and unloading of switch cover plates, reducing the labor cost and being beneficial to the loading and unloading efficiency.

[0077] Referring to Figure 4 、 Figure 9The specific structure of the unloading conveyor assembly 21 is as follows: the unloading conveyor assembly 21 includes an unloading conveyor belt 211 and an unloading driving member 212. The unloading conveyor belt 211 and the unloading driving member 212 are both installed on the second mounting frame 22. The unloading driving member 212 is used to drive the unloading conveyor belt 211 to move. The unloading driving member 212 is a device capable of driving the unloading conveyor belt 211 to work, such as a motor. The unloading conveyor belt 211 is located on the side of the second mounting frame 22 facing the spraying conveyor belt. The length direction of the unloading conveyor belt 211 is consistent with the conveying direction of the spraying conveyor belt. The terminal of the unloading conveyor belt 211 may be provided with a switch cover plate storage device for storing the switch cover plate, or the unloading conveyor belt 211 directly transports the switch cover plate to the next processing station. Limiting plates 213 are arranged on both sides of the spraying transmission belt in the length direction. The limiting plates 213 are used to limit the switch cover plate. The distance between the limiting plates 213 is slightly larger than the width of the switch cover plate, so that the switch cover plate can be easily placed on the unloading conveyor belt 211, and the unloading conveyor belt 211 can transport the switch cover plate more orderly.

[0078] Working principle:

[0079] The switch cover plates are manually stacked in the stacking frame 124, and each conveying drive component 123 is started. The multiple conveying components 12 transport each stacked switch cover plate to the designated position one by one, and the first adsorption subcomponent 135 of the first moving component 13 of the first feeding mechanism 1 adsorbs the switch cover plates from each designated position. The jig moves following the spraying transmission belt. When the jig passes through the first induction sensor 131, the first induction sensor 131 counts the jig. When the number of jigs passing is equal to or greater than the number of first adsorption subcomponents 135, the first X-axis driving subcomponent 136 drives the first X-axis moving table 132 to move, so that each first adsorption subcomponent 135 follows the movement of each jig. When each first adsorption subcomponent 135 catches up with each jig, the first Y-axis driving subcomponent 137 drives the first Y-axis moving table 133 to move, so that the two first clamping rods 141 of each first matching component 14 are respectively located on both sides of the jig. Then, each first linear motion output component 143 works so that the two The first clamping rods 141 are moved closer to each other to clamp the elastic sheet of the fixture, so that the elastic sheets are deformed and moved closer to each other, and then the first Z-direction driving subassembly 138 drives the first Z-direction moving table 134 to move, so that the switch cover plate adsorbed by the first adsorption subassembly 135 is placed on the fixture, and the first linear motion output member 143 drives the first clamping rod 141 to reset, at which time the elastic sheet opens and fixes the switch cover plate, and the first adsorption subassembly 135 no longer provides adsorption force, and then the first X-direction driving subassembly 136, the first Y-direction driving subassembly 137 and the first Z-direction driving subassembly 138 respectively drive the first X-direction moving table 132, the first Y-direction moving table 133 and the first Z-direction moving table 134 to reset. Repeat the above actions, and the feeding mechanism 1 will continuously feed the switch cover plates in batches.

[0080] When the jig after spraying moves to the blanking mechanism 2 along with the spraying conveyor belt, when the jig passes through the second induction sensor, the second induction sensor counts the jig. When the number of jigs passing through is equal to or greater than the number of adsorption sub-assemblies, the second X-direction driving sub-assembly drives the second X-direction moving table to move, so that each second adsorption sub-assembly moves following each jig. After each second adsorption sub-assembly catches up with each jig, the second Y-direction driving sub-assembly drives the second Y-direction moving table to move, so that the two second clamping rods of each second matching assembly 24 are respectively located on both sides of the jig. Then the second Z-direction driving sub-assembly drives the second Z-direction moving table to move, so that each second adsorption sub-assembly approaches each switch cover plate, and the second adsorption sub-assembly provides an adsorption force to adsorb the switch cover plate. Then each second linear motion output member works to make the two second clamping rods approach each other to clamp the elastic piece of the jig, so that the elastic pieces deform and approach each other. At this time, the elastic pieces no longer provide a supporting force to the switch cover plate. Then the second moving assembly 23 of the blanking mechanism 2 drives the switch cover plate to move out from the jig, and the second clamping rods on the second matching assembly 24 reset. Then the second moving assembly 23 moves the switch cover plate to the blanking conveyor belt 211. The second adsorption assembly no longer provides an adsorption force, and the switch cover plate will be separated from the second adsorption assembly. Finally, the switch cover plate will be conveyed to the switch cover plate storage device or the next working station along with the blanking conveyor belt 211.
