[0002] A switch is an electronic component that can open a circuit, interrupt the current, or cause it to flow to other circuits. Common switches include micro switches, rocker switches, toggle switches, push button switches, key switches, etc. Switches generally have multiple components, and during the production process, multiple components need to be assembled into an integral product. Taking a key switch as an example, a common switch key generally includes a base, a shaft, a spring, a moving piece, a static piece, and other components. During the production process, each component needs to be assembled in a certain order. During the assembly process, the base is generally placed on the jig of the corresponding station at the beginning, and then a component is installed into the base through the corresponding equipment. After the component is installed, the combination of the two is transferred to the jig of the next work station, and another component is installed through another device, and so on. In the traditional operation process, each workstation / equipment is generally separated, that is, after the installation of a component is completed, it needs to be collected and then transferred to the next workstation by the staff to install the next component. This method has poor continuity and low efficiency. In order to improve the assembly efficiency, multiple workstations need to be combined together. Therefore, a conveying device is needed that can quickly and accurately transport the switch components to the corresponding workstation. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0023] Reference Figures 1 to 3The utility model provides a conveying device for switch assembly, comprising a base 1, a support frame 11 arranged on the base 1, a conveying path 2 for product movement arranged on the support frame 11, a pushing mechanism 3 arranged on the support frame 11 for pushing the product to move along the conveying path 2, and a product positioning mechanism 4 arranged on the conveying path; the conveying path 2 is provided with a conveying trough 21 for product movement; the pushing mechanism 3 comprises a sliding assembly 31 arranged on the support frame 11, a moving plate 32 connected to the sliding assembly 31, a plurality of material-dipping members 33 evenly arranged on the moving plate 32, and a driving assembly 34 for pushing the moving plate 32 to move, the material-dipping member 33 is located above the conveying path 2, the material-dipping member 33 is rotatably connected to the moving plate 32, and an elastic reset member is connected between the material-dipping member 33 and the moving plate 32. In this embodiment, the elastic reset member can adopt a torsion spring, and the sliding assembly 31 adopts a slider guide assembly.

[0024] There are several product positioning mechanisms 4, and the spacing between adjacent product positioning mechanisms 4 corresponds to the spacing between adjacent material-digging members 33; the product positioning mechanism 4 includes a fixing member 41 connected to the outer wall of the conveying path 2, and a pressing member 42 for pressing the product, one end of the pressing member 42 is inserted from the inner wall of the conveying path 2 and extends through the inner wall of the conveying groove 21 to the conveying groove 21, and the other end of the pressing member 42 is connected to the fixing member 41 through a spring 43. Under the elastic force of the spring 43, the pressing member 42 applies a force to the product component, so that the product component is pressed at the current position, and the limit is achieved. At this time, another product component can be installed.

[0025] A limiting boss 35 is arranged between the adjacent material-digging members 33, and the material-digging member 33 contacts the limiting boss 35 on one side, and there is a gap between the material-digging member 33 and the limiting boss 35 on the other side, that is, the material-digging member 33 is locked in one direction, and when the movable plate 32 moves from the starting end to the end of the conveying path 2, the material-digging member 33 is restricted by the limiting boss 35 and cannot rotate, so that the product component can be pushed to move, and when the movable plate 32 moves in the reverse direction, because there is a gap between the other side of the material-digging member 33 and the limiting boss 35, there is a certain activity space, and the product component is pressed and limited by the product positioning mechanism 4, so that after the material-digging member 33 contacts the product component, the material-digging member 33 can rotate a certain angle (at this time, the elastic reset member is compressed) to avoid the product component and avoid the position of the product component from moving, and after the material-digging member 33 passes the product component, the elastic reset member makes the material-digging member 33 return to the initial position, that is, the whole realizes the one-way transmission of the product component. In this embodiment, a pressing plate 36 is arranged on the movable plate 32.

[0026] The driving assembly 34 includes a driving seat 341, a driving member 342 disposed on the driving seat 341, and the moving plate 32 is provided with a connecting member 343, and the output end of the driving member 342 is connected to the connecting member 343. The driving member 342 adopts a cylinder, and each movement of the cylinder can push the product component forward a set distance, that is, move the product component from one station to another station.

[0027] The support frame 11 is provided with a buffer assembly 5 matched with the connecting member 343, and the buffer assembly 5 includes a buffer frame 51 provided on the support frame 11, and a buffer 52 provided on the buffer frame 51, and the position of the buffer 52 corresponds to the connecting member 343. The buffer assembly 5 can play a buffering and limiting role for the movable plate 32.

[0028] The support frame 11 is provided with a vibration plate 6 for feeding the conveyor 2. In this embodiment, the vibration plate 6 is used to provide a base 1 of a key switch. After the base 1 enters the conveyor 2, it is pushed by the pushing mechanism 3 and moves to each work station in turn to install different components.

[0029] The support frame 11 is provided with a lifting assembly 7 at the starting end corresponding to the conveyor 2, and the lifting assembly 7 includes a lifting cylinder 71 and a receiving seat 72 connected to the lifting cylinder 71 for receiving materials from the vibration plate 6. The vibration plate 6 has a discharge channel, which extends to the starting end of the conveyor 2, and the receiving seat 72 is located between the discharge channel and the conveyor 2. Since the discharge channel is not provided with a product positioning mechanism 4, it is necessary to first send the product parts into the receiving seat 72. After the product parts enter the receiving seat 72, the receiving seat 72 moves downward under the drive of the lifting cylinder 71. At this time, the moving plate 32 of the pushing assembly can move to one side of the vibration plate 6, and the material-digging piece 33 on the front side moves to the discharge channel of the vibration plate 6. Then the lifting cylinder 71 is reset, and the receiving seat 72 rises to a height corresponding to the conveyor 2. At this time, the moving plate 32 moves back, and the material-digging piece 33 can push the product parts into the conveying trough 21.

[0030] The end of the conveying channel 2 is connected to a lower material channel 22. The assembled products flow out from the lower material channel 22, and a material receiving box or a conveyor belt can be arranged below the lower material channel 22.

[0031] The conveying device for switch assembly includes a defective product sorting component 8, the defective product sorting includes a sorting cylinder 81 arranged on the support frame 11, a stopper 82 connected to the output end of the sorting cylinder 81, the conveying path 2 has a through hole 23 that penetrates the conveying path 2 along the width direction near the end, the stopper 82 is plugged into the through hole 23, and a discharge port 24 is arranged at the bottom of the conveying path 2 corresponding to the position of the stopper 82. A discharge channel is arranged below the discharge port 24, and in specific implementation, the discharge channel can be connected to a defective product collection box. After completing the predetermined assembly process, the product will be tested before arriving at the defective product sorting component 8. If it is detected to be unqualified, the stopper 82 will be pulled out from the conveying path 2 under the drive of the sorting cylinder 81, exposing the discharge port 24, and the key will flow out from the discharge port 24 when it continues to move. If it is detected to be qualified, the sorting cylinder 81 will not act, and the key will flow into the discharge channel 22.

[0032] During specific operations, multiple installation stations can be set up along the conveyor 2, and each installation station is provided with corresponding equipment or mechanisms corresponding to the installation of different product components. The specific length of the conveyor 2 can be adaptively set according to the specific assembly process required. If there are many components involved, it is necessary to extend the length of the conveyor 2 so that there is more space to set up the installation station and the corresponding equipment. In the process of assembling the switch button, the vibration plate 6 first sends the base 1 of the switch button into the receiving seat 72, and then the pushing mechanism 3 pushes the base 1 to move along the conveying groove 21, and moves the same distance each time. Taking the first installation station as an example, after the base 1 moves to the first installation station, the base 1 is pressed by the product limit assembly, and the installation equipment or mechanism installs the first product component to the base 1. After the installation is completed, the pushing mechanism 3 pushes the base 1 to continue to move. At this time, the next base 1 also enters the first installation station at the same time, and so on, until all the predetermined assembly processes are completed and the material flows out of the discharge channel 22.
