For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] like Figure 1 As shown, a slider 2 and an adjusting component 4 are provided on the base 1; a fixed block 3 is provided at one end of the slider 2; one side of the fixed block 3 is in contact with the adjusting component 4; a baffle 5 is provided at the end of the slider 2 away from the fixed block 3; a sensing component 6 is provided at the side of the baffle 5 close to the slider 2; a feed rail 8 is provided at the side of the baffle 5 away from the slider 2; a feed clamp 7 is provided at one end of the feed rail 8; a pushing rod 9 is provided in the feed rail 8; and a pressing rod 10 is provided above the feed rail 8.
[0023] Specifically, the base 1 is used to be installed on the processing equipment, and a slider 2 is provided on the base 1, and a slide groove 201 is provided on the slider 2. The slider 2 is slidably connected with the base 1 through the slide groove 201. Under the action of force, the slider 2 slides on the base 1 along the direction guided by the slide groove 201. In some embodiments, a return spring is provided on the slider 2, and under the elastic force of the return spring, the slider 2 makes intermittent reciprocating motion along the slide groove 201 under the push of external force.
[0024] A fixing block 3 is provided at one end of the slider 2, and the fixing block 3 is integrally connected to the slider 2. The fixing block 3 is used to clamp the push rod 403 in the adjustment component 4 to limit the sliding stroke of the slider 2. The extension length of the push rod 403 is adjusted by the adjustment component 4 to control the moving distance of the slider 2. According to the length of the guide needle of different models, the extension amount of the push rod 403 is adjusted accordingly to adapt to the detection of different models of guide needles, thereby improving adaptability.
[0025] A baffle 5 is disposed at one end of the slider 2 away from the fixed block 3 ; a sensing component 6 is disposed at one side of the baffle 5 close to the slider 2 .
[0026] The side of the baffle 5 is vertically fixed to the end of the slider 2, and the baffle 5 moves together with the slider 2. Driven by the slider, the baffle 5 moves away from the side wall of the slider 2 to intermittently approach or move away from the guide needle 13 to be detected, so as to push and limit the guide needle 13 to be detected. The baffle 5 is provided with a needle stopper 502 away from the slider 2. The needle stopper 502 can be set in an arc shape or at an inclined angle, so as to reduce damage to the guide needle 13 when feeding with the guide needle 13, and slide into the feed slide rail 8 on the side of the baffle 5 more accurately.
[0027] A feed rail 8 is provided on the side of the baffle 5 away from the slider 2; a feed fixture 7 is provided at one end of the feed rail 8. The type of the feed rail 8 is not limited and will not be described in detail here. The feed rail 8 of this embodiment is preferably a plate with a smooth and flat surface, and a feed fixture 7 is provided at one end of the feed rail 8. The feed fixture 7 is a manipulator or a flip clamp, which is mainly used to clamp or suck the guide needle 13 to be detected from the upstream station and place it on the feed rail 8.
[0028] A push rod 9 is provided in the feed slide 8. Specifically, the push rod 9 is movably provided on the side wall of the feed slide 8 or on the feed slide 8. A U-shaped opening 901 is provided at the end of the push rod 9. When pushing, the U-shaped opening 901 abuts against the guide pin 13 to be tested. Driven by an external force, the push rod 9 is pushed along the feeding direction of the feed slide 8 to push the guide pins 13 to be tested on the feed slide 8 one by one to the sensing component 6. The guide pins 13 to be tested slide horizontally along the surface of the feed slide 8 into the sensing component 6. A pressing rod 10 is provided above the feed slide 8. An L-shaped opening is provided at the end of the pressing rod 10, wherein the L-shaped opening is used to clamp the guide pin 13 to be tested, and is used to squeeze and fix the guide pin 13 to be tested on the feed slide 8, so that the guide pin 13 to be tested remains in a parallel state and enters the sensing component 6 detection process.
[0029] The adjusting assembly 4 is fixed on the base 1 by a fixing seat 401 ; the adjusting member 402 is movably connected with the top rod 403 ; the adjusting member 402 is used to adjust the extension length of the top rod 403 , and the extension end of the top rod 403 faces one side of the fixing block 3 .
[0030] The specific adjustment component 4 includes a fixed seat 401, an adjustment member 402, and a push rod 403; the fixed seat 401 fixes the adjustment component 4 on the base 1. The adjustment component 4 and the fixed seat 401 play the role of clamping the moving stroke of the slider 2. In some other embodiments, the adjustment component 4 is fixed on the slider 2, and the adjustment component 4 and the fixed seat 401 also play the role of clamping the moving stroke of the slider 2. In some embodiments, the adjustment component 4 can be directly replaced by a known micrometer, which also plays the role of accurately adjusting the moving stroke of the slider 2. In this embodiment, the adjustment member 402 is movably connected with the push rod 403. The extension length of the push rod 403 is controlled by adjusting the adjustment member 402, so that the extended end of the push rod 403 is close to or away from one side of the fixed block 3. When the slider 2 moves, the fixed block 3 will block the movement of the slider 2 and the baffle 5 when it is clamped to the push rod 403. When the push rod 403 is extended longer, the travel of the slider 2 to push the baffle 5 to move is shorter, and when the push rod 403 is extended shorter, the travel of the slider 2 to push the baffle 5 to move is longer. The travel of the baffle 5 is thereby adjusted to be suitable for detecting guide needles 13 of different lengths.
[0031] An opening 501 is provided at the edge where the baffle 5 is connected to the sensing component 6; a stopper 601 is movably provided inside the opening 501. The sensing component 6 includes a first contact piece 602 connected to the stopper 601 and a second contact piece 603 spaced apart from the first contact piece 602; an elastic member 604 is provided between the first contact piece 602 and the second contact piece 603.
[0032] Specifically, Figure 1-4As shown, the guide pin 13 to be tested moves along the feed slide rail 8 under the push of the push rod 9, and the end of the guide pin 13 close to the baffle 5 slides along the side wall of the baffle 5 and finally slides into the opening 501 at the edge of the baffle 5, and enters the detection area of the sensing component 6. The guide pin 13 squeezes the block 601 in the opening 501, so that the block 601 moves toward the test, and the block 601 drives the first contact piece 602 to approach and squeeze the second contact piece 603, so that the first contact piece 602 and the second contact piece 603 are electrically connected. The trigger warning light 12 flashes, and the guide pin 13 is determined to be a qualified product. The next nailing station can be entered to nail the guide pin 13 with aluminum foil.
[0033] A push pin baffle 11 is provided on the side of the feed slide rail 8 away from the baffle 5. The push pin baffle 11 makes intermittent reciprocating motions approaching or moving away from the baffle 5. The push pin baffle 11 pushes the guide pin 13 to be tested to squeeze the side wall of the baffle 5, so that the guide pin 13 to be tested contacts one end of the baffle 5 and slides into the opening 501 and squeezes the stopper 601, triggering the sensing component 6 to work. If the length of the guide pin 13 to be tested is insufficient and is not within the preset length range, the stopper 601 cannot be squeezed, and the sensing component 6 cannot be triggered to work. At this time, the guide pin 13 to be tested is judged to be unqualified, and the equipment can continue to operate only after the unqualified guide pin 13 is eliminated. On the other hand, when the guide pin 13 to be tested is bent, resulting in insufficient total length of the guide pin 13, and the guide pin 13 cannot trigger the sensing component 6, it is also judged to be unqualified, and the equipment stops running.
[0034] The guide pins 13 are detected one by one by the induction component 6, and unqualified products caused by bent guide pins or mixed materials are eliminated, so that the guide pins 13 flowing into the nailing station are all qualified products. The quality and processing efficiency of the product are improved, abnormal guide pins are automatically eliminated, and abnormal guide pins are prevented from being nailed to the aluminum foil, which reduces the loss of aluminum foil and increases the utilization rate of materials. The guide pin detection suitable for different models is fine-tuned by adjusting the component 4, and the precise adjustment reduces the number of machine adjustments and the waste of raw materials. The guide pins that have been screened and eliminated can be nailed accurately to the preset position of the aluminum foil, which improves the nailing efficiency and solves the problem of uneven height of the capacitor leads.
[0035] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
