Description

Technical Field

[0001] This utility model belongs to the field of SMT placement equipment technology, and in particular relates to an impedance detection mechanism and a tape splicing machine. Background Technology

[0002] A pick-and-place machine is a device that uses a moving placement head to accurately place surface mount components onto PCB pads. During production, when the tape in the pick-and-place machine is about to run out, a tape splicer is needed to connect the head of the new tape in the storage cartridge to the tail of the old tape in the pick-and-place machine.

[0003] Before receiving the new material, an LCR meter is needed to measure the inductance (L), capacitance (C), and resistance (R) parameters of the components to determine whether the new material strip is of the same specification as the old material strip. Most existing inspection methods are manual, which involves manually removing the film from the material strip and inserting the detection end of the LCR meter into the new material strip to contact the components. Obviously, manual inspection is not only inefficient and does not meet the requirements of fast-paced production, but also prone to errors and inaccuracies, resulting in low inspection quality. Utility Model Content

[0004] The purpose of this invention is to provide an impedance detection mechanism and a tape splicing machine to solve the problem of low detection efficiency in conventional manual detection methods in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, an impedance detection mechanism is provided, comprising a base, a driving unit, and a detection unit, wherein: The base is located on one side of the strip to be inspected. The detection unit is movably mounted on the base. The fixed end of the drive unit is mounted on the base. The drive end of the drive unit is insulated from the detection unit. The drive unit is at least configured to drive the detection unit to move up or down to a high or low position. The detection end of the detection unit is provided with a puncturing element for puncturing the film on the strip. When the detection unit is in a low position, the piercing element of the detection unit pierces the upper film of the material strip and contacts the detection end of the product in the material hole to perform impedance detection on the product in the material hole.

[0006] Furthermore, the detection unit includes a detection frame, and the piercing element is disposed at the bottom of the detection frame. The piercing element includes two spaced-apart tips. The first end of each tip is detachably mounted on the bottom of the detection frame, and the second end of each tip extends downward. The tip as a whole has an inverted triangular structure that is larger at the top and smaller at the bottom.

[0007] Furthermore, an insulating element is provided at the first end of the pointed tip, a through hole is provided in the middle of the insulating element, a first threaded hole is provided at the first end of the pointed tip, and a second threaded hole adapted to the first threaded hole is provided at the bottom of the testing frame. The bolt passes through the first threaded hole, the through hole and the second threaded hole in sequence and is then tightened at the bottom of the testing frame to screw the insulating element between the first end of the pointed tip and the bottom of the testing frame.

[0008] Furthermore, the insulating element is a rectangular insulating block or a ring-shaped insulating block.

[0009] Furthermore, the driving unit includes a first driving assembly, which includes a first driving member and a lifting member. The detection unit is mounted on the lifting member, which is movably disposed on the base. The fixed end of the first driving member is mounted on the base, and the driving end of the first driving member is connected to the lifting member. The first driving member is configured to drive the lifting member to move up and down, thereby driving the detection unit to move up and down.

[0010] Furthermore, a first transmission pair is provided between the first driving member and the lifting member. The first transmission pair includes a first transmission screw and a first nut. The first transmission screw is rotatably mounted on the base along its own axis. The first nut is fixed on the lifting member and sleeved on the first transmission screw. The driving end of the first driving member is connected to the first transmission screw. The first driving member is configured to drive the first transmission screw to rotate along its own axis. The first driving member drives the lifting member to rise and fall through the transmission cooperation of the first transmission screw and the first nut.

[0011] Furthermore, the drive unit also includes a second drive assembly, which includes a second drive member, a second transmission pair, and a traverse member. The traverse member is reciprocally mounted on the lifting member in a horizontal direction. The detection unit is mounted on the traverse member. The fixed end of the second drive member is mounted on the lifting member. The drive end of the second drive member is connected to the first end of the second transmission pair, and the second end of the second transmission pair is connected to the traverse member. The second transmission pair includes a second transmission screw and a second nut. The second transmission screw is rotatably mounted on the lifting member along its own axis. The second nut is fixed on the transverse member and sleeved on the second transmission screw. The driving end of the second driving member is connected to the second transmission screw. The second driving member is configured to drive the second transmission screw to rotate along its own axis. The second driving member drives the transverse member to move laterally through the transmission cooperation of the second transmission screw and the second nut, thereby causing the detection part to move laterally and thus avoid external mechanisms.

[0012] Furthermore, the drive unit also includes a distance adjustment assembly, which includes a distance adjustment seat, a distance adjustment drive, and two adjustment members. The distance adjustment seat is detachably mounted on the detection frame. The two adjustment members are disposed on the distance adjustment seat and can be close to or far from each other. Each adjustment member corresponds to a pointed tip, and the first end of each pointed tip is mounted on the corresponding adjustment member. The fixed end of the distance adjustment drive is mounted on the distance adjustment seat, and the drive end of the distance adjustment drive is connected to one or both adjustment members. The distance adjustment drive is configured to drive the two adjustment members to move closer to or further away from each other to adjust the distance between the two pointed tips.

[0013] Furthermore, a sliding guide pair is provided between the lifting component and the base. The sliding guide pair includes a linear guide rail and a slider. The linear guide rail is laid on the base along the height direction, and the slider is fixed on the lifting component and slidably sleeved on the linear guide rail.

[0014] Secondly, a material strip splicing machine is provided, which includes the aforementioned impedance detection mechanism.

[0015] Compared with the prior art, the advantages of the impedance detection mechanism and the tape splicing machine are as follows: 1) Through the cooperation of the drive unit and the detection unit, the detection end of the detection unit is equipped with a piercing element for piercing the film on the material strip. The drive unit drives the detection unit to a low position. The piercing element of the detection unit pierces the film on the material strip and contacts the detection end of the product in the material hole, and performs impedance detection on the product in the material hole. The detection method is simple and easy to implement, which greatly improves the detection efficiency. At the same time, the detection unit descends to the same height each time, avoiding errors during detection and further improving the detection quality. 2) By setting the puncture component as two inverted triangular structures with the upper part larger than the lower part, it is easier for the puncture component to puncture the upper film of the material strip when the detection part is in a low position, which reduces the contact time between the detection end and the detection end of the product and further improves the detection efficiency.

[0020] Please see Figures 1 to 4 As shown, in this embodiment, an impedance detection mechanism includes a base 10, a driving unit 20, and a detection unit 30. The base 10 is located on one side of the strip to be tested. The detection unit 30 is movably mounted on the base 10. The fixed end of the driving unit 20 is mounted on the base 10. The driving end of the driving unit 20 is insulated from the detection unit 30. The driving unit 20 is configured to drive the detection unit 30 to a high or low position. The detection end of the detection unit 30 is provided with a piercing element 31 for piercing the film on the strip. When the detection unit 30 is in the low position, the piercing element 31 of the detection unit 30 pierces the film on the strip and contacts the detection end of the product in the material hole to perform impedance detection on the product in the material hole.

[0021] Specifically, the testing section 30 is an LCR meter, which can measure the inductance (L), capacitance (C), and resistance (R) parameters of the product.

[0022] As can be seen, through the cooperation of the drive unit 20 and the detection unit 30, the detection end of the detection unit 30 is provided with a piercing element 31 for piercing the film on the material strip. The drive unit 20 drives the detection unit 30 to a low position, and the piercing element 31 of the detection unit 30 pierces the film on the material strip and contacts the detection end of the product in the material hole, and performs impedance detection on the product in the material hole. The detection method is simple and easy to implement, which greatly improves the detection efficiency. At the same time, the detection unit 30 descends to the same height each time, avoiding errors during detection and further improving the detection quality.

[0023] In one embodiment, the detection unit 30 includes a detection frame 32, and a piercing member 31 is disposed at the bottom of the detection frame 32. The piercing member 31 includes two spaced-apart tips 33. The first end of each tip 33 is detachably mounted on the bottom of the detection frame 32, and the second end of each tip 33 extends downward. The tip 33 as a whole has an inverted triangular structure that is larger at the top and smaller at the bottom.

[0024] It can be seen that by setting the puncturing element 31 as two inverted triangular structures with the upper part larger than the lower part, when the detection part 30 is in a low position, it is easy for the puncturing element 31 to puncture the upper film of the material strip, thereby reducing the contact time between the detection end and the detection end of the product and further improving the detection efficiency.

[0025] In one embodiment, an insulating member 40 is provided at the first end of the tip 33, and a through hole is provided in the middle of the insulating member 40.

[0026] Specifically, the insulating component 40 is a rectangular insulating block or a ring-shaped insulating block.

[0027] Of course, as another implementation method, the insulating element 40 can also be an insulating gasket.

[0028] It is evident that by setting the insulating component 40, the electrical conduction of current can be effectively blocked, preventing electrical faults such as short circuits caused by accidental contact between the tip 33 and the testing frame 32, thus ensuring electrical safety during the testing process and the normal operation of related electrical equipment.

[0029] In one embodiment, the drive unit 20 includes a first drive assembly, which includes a first drive member 21 and a lifting member 22. The detection unit 30 is mounted on the lifting member 22. The lifting member 22 is movably mounted on the base 10. The fixed end of the first drive member 21 is mounted on the base 10, and the drive end of the first drive member 21 is connected to the lifting member 22. The first drive member 21 is configured to drive the lifting member 22 to move up and down, thereby driving the detection unit 30 to move up and down.

[0033] It can be seen that the cooperation of the first driving component 21 and the lifting component 22 enables the detection unit 30 to be driven to a high or low position, providing a first driving component with a simple structure and high driving accuracy.

[0034] In one embodiment, a first transmission pair 23 is provided between the first driving member 21 and the lifting member 22. The first transmission pair 23 includes a first transmission screw 230 and a first nut 231. The first transmission screw 230 is rotatably mounted on the base 10 along its own axis. The first nut 231 is fixed on the lifting member 22 and sleeved on the first transmission screw 230. The driving end of the first driving member 21 is connected to the first transmission screw 230. The first driving member 21 is configured to drive the first transmission screw 230 to rotate along its own axis. The first driving member 21 drives the lifting member 22 to rise and fall through the transmission cooperation of the first transmission screw 230 and the first nut 231.

[0035] As can be seen, through the cooperation of the first transmission screw 230 and the first nut 231, the first driving member 21 drives the first transmission screw 230 to rotate along its own axis, effectively driving the lifting member 22 to rise and fall, providing a transmission pair with high transmission accuracy and high transmission efficiency.

[0036] In one embodiment, the drive unit 20 further includes a second drive assembly, which includes a second drive member 24, a second transmission pair 25, and a lateral movement member 26. The lateral movement member 26 is reciprocally mounted on the lifting member 22 in a horizontal direction. The detection unit 30 is mounted on the lateral movement member 26. The fixed end of the second drive member 24 is mounted on the lifting member 22.

Nut 251 and second transmission screw 250 are rotatably mounted on lifting member 22 along their own axis. The second nut 251 is fixed on transverse member 26 and sleeved on second transmission screw 250. The driving end of second drive member 24 is connected to second transmission screw 250. Second drive member 24 is configured to drive second transmission screw 250 to rotate along its own axis. Second drive member 24 drives transverse member 26 to move laterally through the transmission cooperation of second transmission screw 250 and second nut 251, so as to drive detection unit 30 to move laterally and thus avoid external mechanism.

[0037] Specifically, the second driving component 24 is a drive motor.

[0038] Specifically, the second drive component can be a cylinder, a motor, or a drive module with linear stroke.

[0039] Specifically, the transverse component 26 is a transverse plate.

[0040] As can be seen, through the cooperation of the second transmission screw 250 and the second nut 251, the second driving member 24 drives the second transmission screw 250 to rotate along its own axis, effectively driving the transverse member 26 to move laterally, providing a transmission pair with high transmission accuracy and high transmission efficiency.

[0041] In one embodiment, the drive unit 20 further includes a pitch adjustment assembly, which includes a pitch adjustment seat, a pitch adjustment drive 27, and two adjustment members. The pitch adjustment seat is detachably mounted on the detection frame 32. The two adjustment members are arranged on the pitch adjustment seat with their distance from each other.

The fixed end of the pitch adjustment drive 27 is mounted on the pitch adjustment seat. The drive end of the pitch adjustment drive 27 is connected to one or both adjustment members. The pitch adjustment drive 27 is configured to drive the two adjustment members to move closer or further apart to adjust the distance between the two tips 33.

[0042] Specifically, the pitch control drive component 27 is a drive motor.

[0043] It can be seen that by cooperating with the pitch adjustment drive 27 and the two adjustment components, the distance between the two pointed tips 33 can be adjusted, which can be used to inspect strips of different specifications, further improving the versatility of the inspection.
