Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a moving contact detection device. Background Technology

[0002] A switch is an electronic component that can open a circuit, interrupt current, or divert current to another circuit. A microswitch is a type of switch, characterized by its tiny contact spacing, quick-acting mechanism, and switching action with a specified stroke and force. It is enclosed in a housing and has an external actuator. Because of its small contact spacing, it is called a microswitch, also known as a sensitive switch. A typical microswitch includes a base, a housing, a moving contact (also called a spring) positioned between the base and housing, and conductive terminals. These components need to be assembled into a product during manufacturing. During the soldering process of the moving contact, it is difficult to guarantee 100% soldering quality, and defects such as detachment or misalignment may occur. These defects affect the operational reliability and lifespan of the final product. To ensure that the final product meets design requirements, the moving contact needs to be inspected before assembly to determine if it conforms to design standards, thus ensuring the conductivity and lifespan of the subsequent product. Traditionally, this inspection is done manually, but manual inspection is arduous, inefficient, and prone to significant errors due to fatigue. Utility Model Content

[0023] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0024] Reference Figures 1 to 4 This utility model provides a moving piece contact detection device, including a housing 1, a support frame 11 mounted on the housing 1, a moving piece guiding mechanism 2 mounted on the support frame 11, a moving piece detection mechanism 3 mounted on the support frame 11, a defective product discharge mechanism 4 mounted on the moving piece guiding mechanism 2, and a traction mechanism 5 mounted on the housing 1 for moving the moving pieces. The moving piece detection mechanism 3, the defective product discharge mechanism 4, and the traction mechanism 5 are arranged sequentially. Multiple moving pieces are connected to the same conveyor belt; the traction mechanism 5 moves the conveyor belt, and the moving pieces move accordingly.

[0025] The moving piece detection mechanism 3 includes a detection bracket 31 mounted on the support frame 11, a vision sensor 32 connected to the detection bracket 31, and a supplementary lighting component 33 mounted on the support frame 11, the supplementary lighting component 33 being located below the vision sensor 32. When the moving piece reaches below the vision sensor 32, the vision sensor 32 acquires an image of the current moving piece and compares it with a pre-stored standard product image to determine whether the current moving piece contact meets the design requirements.

[0026] The defective product discharge mechanism 4 includes a defective product support base 41 disposed on the moving piece guide mechanism 2, and a discharge cylinder 42 disposed on the defective product support base 41. When the moving piece detection mechanism 3 detects a defective contact of the moving piece, it marks the moving piece. When the moving piece moves to below the discharge cylinder 42 of the defective product discharge mechanism 4, the piston rod of the discharge cylinder 42 extends and presses down the moving piece until the moving piece disengages from the conveyor belt, thus completing the discharge of the defective product. In specific implementation, a pressing component or a cutter can be connected to the piston rod of the discharge cylinder 42 to ensure that the moving piece disengages from the conveyor belt.

[0027] The moving sheet guiding mechanism 2 includes a guide plate 21 mounted on the support frame, a first pressure plate 22 and a second pressure plate 23 mounted on the guide plate 21, with a gap between the first pressure plate 22 and the second pressure plate 23. A guide groove 24 is provided at the corresponding gap position on the guide plate 21. Specifically, the material strip can move along the guide groove 24, while the first pressure plate 22 and the second pressure plate 23 limit the material strip in the vertical direction to prevent it from detaching from the guide groove 24. In this embodiment, there are two guide grooves 24, and the second pressure plate 23 is positioned between the two guide grooves 24. Simultaneously, there are two first pressure plates 22, respectively positioned outside the two guide grooves 24. Furthermore, two moving sheet detection mechanisms 3 and two defective product discharge mechanisms 4 are also required, meaning that this embodiment can simultaneously perform detection operations on two material strips.

[0028] The supplementary lighting component 33 includes a fixing block 331 connected to the support frame 11, a fixing plate 332 disposed on the fixing block 331, and a light source 333 connected to the fixing plate 332. The light source 333 is a ring light source 333 with a through hole in the middle.

[0029] The support frame 11 is provided with a discharge channel 12 corresponding to the defective product discharge mechanism 4, and the chassis 1 is provided with a receiving box 13 corresponding to the discharge channel 12. The support frame 11 includes a column on the chassis 1 and a support plate on the top of the column. The discharge channel 12 is connected to the bottom surface of the support plate, and the support plate has an opening corresponding to the discharge channel 12. After the defective product is separated from the conveyor belt by the discharge cylinder 42, it falls into the discharge channel 12 and finally enters the receiving box.

[0030] The traction mechanism 5 includes a traction bracket 51, a traction seat 52 mounted on the traction bracket 51, a traction shaft 53 connected to the traction seat 52, a traction wheel 54 mounted on the traction shaft 53, and a traction motor 55 mounted on the traction bracket 51 for driving the traction shaft 53 to rotate. The traction wheel 54 has several traction parts on its outer periphery, and the material belt has holes matching the traction parts. Thus, when the traction wheel 54 rotates, it can pull the material belt to move. The traction wheel 54 performs a step-like movement with a specific rhythm, that is, it rotates the same angle each time, and then stops for a certain period of time to wait for the moving piece detection mechanism 3 to perform detection. The rotation angle and the specific stopping time can be adaptively set according to actual needs. In this embodiment, there are two traction wheels 54, each corresponding to one of the two guide grooves 24.

[0031] The moving contact detection mechanism further includes a feeding mechanism 6 and a receiving mechanism 7 mounted on the chassis 1. The feeding mechanism 6, the moving contact detection mechanism 3, the defective product discharge mechanism 4, the traction mechanism 5, and the receiving mechanism 7 are arranged sequentially. Both the feeding mechanism 6 and the receiving mechanism 7 include a fixed bracket 61, a rotating shaft 62 mounted on the fixed bracket 61, a material tray 63 mounted on the rotating shaft 62, and a drive motor 64 mounted on the fixed bracket 61 for driving the rotating shaft 62 to rotate. The material strip to be tested is pre-wound onto the material tray 63 to form a material strip roll. After the material tray 63 is installed onto the rotating shaft 62, the drive motor 64 can drive the rotating shaft 62 to rotate, thereby causing the material tray 63 to rotate, realizing unwinding or rewinding. The feeding mechanism 6 is used to place the material strip roll to be tested, while the receiving mechanism 7 is used to wind the tested material strip.

[0032] A sensing component 8 is provided on the fixed bracket. The sensing component 8 includes a connector 81 connected to the fixed bracket 61 and a sensing rod 82 disposed on the connector 81. The sensing rod 82 can sense whether the material belt is in contact with it. That is, when the material belt is not detected, it is necessary to replenish the material. At this time, a prompt can be issued to remind the staff to replenish the material.

[0033] The support frame 11 is equipped with a sensing mechanism 9 for sensing the moving piece. The sensing mechanism 9 is located between the moving piece detection mechanism 3 and the defective product discharge mechanism 4. The sensing mechanism 9 includes a sensing bracket 91 mounted on the support frame 11 and a sensor 92 connected to the sensing bracket 91. The sensor 92 is a laser sensor that can sense whether the conveyor belt has moved into position. The conveyor belt moves the distance of one moving piece at a time. After the sensor 92 senses the moving piece below, it can determine how long it will take for the marked defective product to reach the discharge cylinder 42, allowing the discharge cylinder 42 to discharge the defective product.

[0034] A controller 14 is installed on the chassis 1. The controller 14 has function buttons and a display screen, which can set and display processing parameters and control the operation of the equipment.

[0035] In actual operation, the tray 63 containing the strip to be tested is first installed on the feeding mechanism 6, and an empty tray 63 is simultaneously installed at the receiving mechanism 7. After the end of the strip to be tested enters from one end of the guide groove 24, it extends from the other end of the guide groove 24 and connects to the empty tray 63 of the receiving mechanism 7. During testing, the feeding mechanism 6 pre-releases a certain length of strip, and the traction mechanism 5 pulls the strip one moving piece at a time. The moving piece detection mechanism 3 detects the moving piece contacts. If a defective product is detected, it is marked. When the moving piece reaches the defective product discharge mechanism 4, the discharge cylinder 42 presses down the marked defective product, causing the defective product to separate from the strip. Then the strip leaves the guide groove 24 and is wound up by the tray 63 of the receiving mechanism 7, completing the testing.

[0036] This invention features a moving sheet guiding mechanism 2 and a moving sheet detection mechanism 3. With the assistance of a traction mechanism 5, the conveyor belt carrying the moving sheet passes under the vision sensor 32 of the moving sheet detection mechanism 3 at a specific rhythm for automatic detection, eliminating the need for manual operation, thus improving work efficiency and ensuring detection accuracy. Furthermore, the defective product discharge mechanism 4 of this invention can separate defective products from the conveyor belt, preventing them from being carried to subsequent processes and ensuring product quality.
