Description

Technical Field

[0001] This utility model relates to the field of SMT tape splicing technology, and in particular to a compatible tape pressing structure and tape clip. Background Technology

[0002] The core equipment of SMT (Surface Mount Technology) is the SMT pick-and-place machine, which can automatically pick up components and accurately place them on the PCB through an electronic eye recognition device. When the tape in the pick-and-place machine is about to run out, a tape receiving machine is needed to connect the new tape head in the storage cartridge with the old tape tail in the pick-and-place machine. Therefore, the tape receiving machine is usually equipped with a cartridge for temporarily storing new tape trays. In order to transport the tape head of the new tape tray toward the receiving platform, each cartridge is equipped with a storage platform and a rotatable conveyor ratchet. The tape head of the new tape tray is placed on the storage platform, and the teeth of the conveyor ratchet need to be manually inserted into the corresponding clamping hole on the tape head. The feeding drive drives the conveyor ratchet to rotate to complete the conveying of the tape head of the new tape tray.

[0003] In the process of placing the strip head of the new material tray onto the storage platform, the strip head of the new material tray needs to be manually led out and pressed onto the storage platform by the pressing mechanism. The existing pressing mechanism includes a pressing block that can be detachably installed on the pressing platform. The pressing block presses the strip head of the new material tray onto the storage platform. However, the gap between the existing pressing block and the storage platform is fixed, so it can only be used for one type of strip and cannot reliably press strips of different thicknesses.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Please see Figures 1 to 6 As shown in the embodiment of this application, a compatible strip pressing structure is provided, which includes a carrier 10 and a pressing assembly 20, wherein:

[0038] The support member 10 is provided with a first horizontal direction ( Figure 1 A limiting groove 11 extending in the direction of X is configured to carry the material strip drawn out from the material tray;

[0039] The pressing assembly 20 includes a base 21 and a pressing element 22. The base 21 is detachably mounted on the support member 10. The pressing element 22 is mounted on the base 21 and can float up and down. The bottom end of the pressing element 22 extends into the limiting groove 11. The pressing element 22 is configured to float and press against the top surface of the material strip in the limiting groove 11 to position the material strip on the support surface of the limiting groove 11.

[0040] By setting a vertically floating pressing element 22 below the base 21, the pressing element 22 can always float and press against the top surface of the strip in the limiting groove 11, thereby reliably pressing strips of different thicknesses and having good compatibility.

[0041] In one embodiment, the pressing assembly 20 further includes a spring plate 23 and a plurality of compression springs 24, wherein:

[0042] A limit component 25 is provided between the base 21 and the pressure member 22. The limit component 25 is configured to limit the downward movement of the pressure member 22.

[0043] Several compression springs 24 are spaced apart between the base 21 and the pressure member 22 along the first horizontal direction. The spring pressure plate 23 is detachably installed on the top surface of the base 21 and covers all the compression springs 24. The top end of the compression spring 24 abuts against the spring pressure plate 23, and the lower end of the compression spring 24 abuts against the top surface of the pressure member 22 to apply a downward elastic force to the pressure member 22.

[0044] Specifically, a number of compression springs 24 are evenly spaced along the first horizontal direction to provide a uniform downward elastic force to the pressure member 22.

[0045] By setting a detachable spring pressure plate 23 on the base 21, it ensures stable contact with several compression springs 24 while facilitating the installation of compression springs 24, thereby improving the overall working efficiency of the mechanism.

[0046] In one embodiment, the pressing assembly 20 further includes a plurality of compression springs 24, and a limit assembly 25 is provided between the base 21 and the pressing member 22. The limit assembly 25 is configured to limit the downward movement of the pressing member 22.

[0047] Several compression springs 24 are spaced apart between the base 21 and the pressure member 22 along the first horizontal direction. Several limiting holes 214 are opened on the bottom surface of the base 21. Each limiting hole 214 corresponds to a compression spring 24. The upper end of the compression spring 24 abuts against the bottom surface of the limiting hole 214, and the lower end of the compression spring 24 abuts against the top surface of the pressure member 22 to apply a downward elastic force to the pressure member 22.

[0048] By setting limiting holes 214 on the base 21 corresponding to the compression springs 24, it is ensured that several compression springs 24 are stably abutted, and the upper end of the compression springs 24 is prevented from shifting. At the same time, the overall structure of the pressing assembly 20 is simplified and the operation is convenient.

[0049] In one embodiment, the top surface of the pressure member 22 is provided with a plurality of mounting holes 221 evenly spaced along the first horizontal direction. Each mounting hole 221 corresponds to a compression spring 24, and the lower end of the compression spring 24 is inserted into the corresponding mounting hole 221.

[0050] By setting a number of mounting holes 221 on the top surface of the pressure member 22 corresponding to the compression spring 24, it is ensured that the compression spring 24 is stably abutted on the pressure member 22, which avoids displacement of the compression spring 24 and ensures that the compression spring 24 provides elastic force in the vertical direction, thus ensuring the pressing effect of the pressure member 22.

[0051] In one embodiment, the limiting component 25 includes a limiting boss 250 and a limiting protrusion 251, wherein:

[0052] The limiting boss 250 is provided on the bearing member 10. The pressure member 22 extends at both ends along the first horizontal direction and is provided with limiting protrusions 251. The limiting boss 250 and the limiting protrusions 251 interfere with each other in the vertical direction. When the pressure member 22 floats to the lowest end, the bottom surface of the limiting protrusion 251 abuts against the top surface of the limiting boss 250.

[0053] Specifically, a single limiting boss 250 and a single limiting protrusion 251 are set in a vertical direction.

[0054] Specifically, when the strip without material passes through the limiting groove 11, the bottom surface of the limiting protrusion 251 abuts against the top surface of the limiting protrusion 250; when the strip with material passes through the limiting groove 11, the top surface of the strip abuts against the bottom surface of the pressing component 22, and the pressing component 22 is lifted up by the strip.

[0055] By cooperating with the limiting boss 250 and the limiting protrusion 251, the pressing part 22 is limited in the vertical direction, which prevents the pressing part 22 from falling or being pressed down excessively, and further ensures the safety and stability of the pressing process.

[0056] In one embodiment, a magnetic attraction component is installed on the base 21 and / or the carrier 10, and the base 21 is attracted and mounted on the carrier 10 by the magnetic attraction component.

[0057] By setting up magnetic attraction components to magnetically attract the base 21 and the carrier 10, a simple and easy-to-implement connection method is provided while ensuring that the base 21 and the carrier 10 are relatively fixed.

[0058] In one embodiment, the magnetic component is mounted on the carrier 10, and the base 21 is made of iron.

[0059] Specifically, the magnetic attraction component includes a magnetic block 212, and the carrier 10 has a receiving groove 15, in which the magnetic block 212 is detachably installed.

[0060] The receiving groove 15 is opened on the upper end surface of the support member 10 on the side of the limiting groove 11 extending along the first horizontal direction. The magnetic block 212 is disposed on the receiving groove 15. The bottom surface of the base 21 is provided with a rectangular protrusion 213, and a receiving cavity is provided in the rectangular protrusion 213. The rectangular protrusion 213 is adapted to the receiving groove 15 and the magnetic block 212 is adapted to the receiving cavity. When the base 21 is placed on the support member 10, the rectangular protrusion 213 fits into the receiving groove 15, ensuring that the base 21 can be accurately placed at the preset position on the support member 10.

[0061] By setting the base 21 to an iron material and setting the magnetic part on the carrier 10, a convenient and quick magnetic attraction method is provided.

[0062] In another embodiment, the magnetic component is mounted on the base 21, and the support member 10 is made of iron.

[0063] In another embodiment, magnetic components are installed on both the base 21 and the carrier 10, with the magnetic components on the base 21 having opposite polarities to those on the carrier 10.

[0064] In one embodiment, the carrier 10 is disposed at the discharge end of the material strip clip, and an avoidance gap 12 extending in the first horizontal direction is provided between the base 21 and the carrier 10. The avoidance gap 12 is connected to the limiting groove 11. The avoidance gap 12 is configured to avoid the conveying ratchet. The avoidance gap 12 corresponds in the height direction to the material clamping hole of the material strip located in the limiting groove 11.

[0065] Specifically, the bottom surface of the base 21 is provided with a limiting protrusion 210 extending downward and in the first horizontal direction. When the base 21 is placed on the bearing member 10, the side wall of the limiting protrusion 210 away from the avoidance gap 12 abuts against the side wall of the limiting groove 11, which further ensures the accuracy of the position of the base 21 in the first horizontal direction.

[0066] Specifically, the upper end face of the bearing member 10 is detachably provided with a pad 13 located on the second side of the limiting groove 11 in the first direction, and the base 21 is provided with a notch 211 to avoid the pad 13. The base 21 is located along the second horizontal direction. Figure 1 A clearance gap 12 is formed between the Y direction and the pad 13, and the first horizontal direction is perpendicular to the second horizontal direction.

[0067] By setting an avoidance gap 12 between the carrier 10 and the base 21 and connecting the gap with the limiting groove 11, the conveying ratchet can be effectively avoided during the material belt transmission process, thus avoiding interference. This not only saves space but also improves the collaborative working ability between the pressing structure and the feeding mechanism, ensuring the stable transportation of the material belt.

[0068] In one embodiment, a relief groove 110 extending in a first direction is provided on the bearing surface of the limiting groove 11 corresponding to the relief gap 12. The relief groove 110 is configured to avoid the teeth of the conveying ratchet when the conveying ratchet is inserted into the clamping hole of the conveying belt, so that the teeth of the conveying ratchet can be inserted into the clamping hole of the conveying belt head.

[0069] By setting an avoidance groove 110 on the bearing surface of the limiting groove 11, an avoidance space is provided for the teeth of the conveying ratchet to enter the material clamping hole, ensuring that the ratchet teeth can be smoothly inserted into the material belt hole during the feeding process, thereby improving the feeding accuracy and smoothness.
