A high-precision positioning device for terminal crimping

Abstract

This utility model discloses a high-precision positioning device for terminal crimping, including a base, a base plate, a carrier, and a locking and positioning structure. The bottom of the base has a first vacuum adsorption chamber, and the top of the base has a through groove communicating with the first vacuum adsorption chamber. The base plate is fixedly connected to the bottom of the base. This utility model initially positions and fixes the FPC / FFC ribbon cable terminal in the contour positioning groove of the carrier. Then, by operating a vacuum generator and opening a solenoid valve, a vacuum is drawn into the first and second vacuum adsorption chambers, generating suction at the vacuum adsorption holes. This suction force is then used to adsorb and fix the FPC / FFC ribbon cable terminal in the contour positioning groove, ensuring the flatness of the FPC / FFC ribbon cable terminal at the crimping position and avoiding relative displacement of the FPC / FFC ribbon cable terminal during the clamping process of the clamping mechanism, which could cause problems such as ribbon cable crimping offset or abnormal length.

Description

Technical Field

[0001] This utility model relates to the field of terminal crimping and positioning technology, specifically a high-precision positioning device for terminal crimping. Background Technology

[0002] Existing FPC / FFC cable terminal crimping machines require the FPC / FFC cable terminals to be fixed before crimping. Currently, this is done using a mechanical shape positioning platform, which positions the cable based on its shape. After positioning, the machine's clamping mechanism holds the product in place. However, uneven product surfaces can cause relative displacement during clamping, resulting in cable crimping misalignment or abnormal length. Therefore, a high-precision positioning device for terminal crimping needs to be designed to address these issues. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a high-precision positioning device for terminal crimping, which aims to solve the problem that when FPC / FFC cable terminals are crimped and fixed, uneven product surfaces can cause relative displacement of the product during the clamping process, resulting in cable crimping offset or abnormal length.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-precision positioning device for terminal crimping, comprising:

[0006] The base has a first vacuum adsorption chamber at its bottom and a through groove at its top that communicates with the first vacuum adsorption chamber.

[0007] A base plate, which is fixedly connected to the bottom of the base;

[0008] The carrier is mounted on the top of the base. The top of the carrier has a contour positioning groove, and the bottom of the carrier has a second vacuum adsorption chamber. A plurality of vacuum adsorption holes are provided between the second vacuum adsorption chamber and the contour positioning groove. The through groove is placed inside the second vacuum adsorption chamber.

[0009] A locking and positioning structure is provided between the carrier and the base and bottom plate, and is used for positioning and detachable installation of the carrier.

[0010] Preferably, an air pipe communicating with the first vacuum adsorption chamber is fixedly connected to the outer wall of the base, and an electromagnetic valve is provided on the air pipe.

[0011] Preferably, the bottom of the base has a first sealing groove outside the first vacuum adsorption chamber, and a first sealing ring is installed in the first sealing groove.

[0012] Preferably, a second sealing groove is provided at the bottom of the carrier outside the second vacuum adsorption chamber, and a second sealing ring is installed in the second sealing groove.

[0013] Preferably, the locking and positioning structure includes four rectangularly distributed guide posts fixedly connected to the bottom of the vehicle and four guide sleeves embedded in the base. The guide sleeves correspond one-to-one with the guide posts, and the guide posts are inserted into the guide sleeves.

[0014] Preferably, the locking and positioning structure further includes threaded posts fixedly connected to both sides of the bottom of the carrier. The base has a first through hole corresponding to the position of the threaded post, and the bottom plate has a second through hole corresponding to the position of the threaded post. The bottom end of the threaded post passes through the first through hole and the second through hole and is threadedly connected to a locking nut. The locking nut is pressed against the bottom of the bottom plate.

[0015] Preferably, extension plates are fixedly connected to both sides of the carrier.

[0016] Preferably, mounting plates are fixedly connected to both sides of the base plate, and the mounting plates are provided with fixing holes.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model initially positions and fixes the FPC / FFC ribbon cable terminals in the contour positioning groove of the carrier. Then, by operating the vacuum generator and opening the solenoid valve, a vacuum is drawn into the first and second vacuum adsorption chambers, generating suction at the vacuum adsorption holes. This adsorbs and fixes the FPC / FFC ribbon cable terminals in the contour positioning groove, ensuring the flatness of the FPC / FFC ribbon cable terminals at the crimping position. This avoids relative displacement of the FPC / FFC ribbon cable terminals during the clamping process of the clamping mechanism, which could cause problems such as ribbon cable crimping offset or abnormal length.

[0019] 2. This utility model, through its locking and positioning structure, ensures the accuracy of the alignment between the carrier and the base by inserting the guide post on the carrier into the guide sleeve on the base during assembly of the carrier, base, and bottom plate. The threaded post passes through the first and second through holes and is connected to the threaded post by a locking nut, which is then pressed against the bottom of the bottom plate to fix the carrier and base in place. This also allows the carrier to be pressed towards the base, facilitating disassembly and replacement of the carrier. Different shaped contour positioning grooves can be used, making it suitable for positioning and fixing FPC / FFC cable terminals of different specifications, thus improving its applicability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example: Please refer to Figures 1-4This embodiment provides a high-precision positioning device for terminal crimping, including a base 1, a base plate 2, a carrier 4, and a locking and positioning structure. The base 1 has a first vacuum adsorption cavity 101 at its bottom and a through groove 102 communicating with the first vacuum adsorption cavity 101 at its top. The base plate 2 is fixedly connected to the bottom of the base 1 by bolts. The carrier 4 is mounted on the top of the base 1. The top of the carrier 4 has a contour positioning groove 401 adapted to the shape of the FPC / FFC cable terminal. The bottom of the carrier 4 has a second vacuum adsorption cavity 403. Several vacuum adsorption holes 402 are formed between the second vacuum adsorption cavity 403 and the contour positioning groove 401. The through groove 102 is placed within the second vacuum adsorption cavity 403 and connects the first vacuum adsorption cavity 101 and the second vacuum adsorption cavity 403. The locking and positioning structure is positioned between the carrier 4 and the base 1 and base plate 2. For the positioning and detachable installation of the carrier 4, an air pipe 5 communicating with the first vacuum adsorption chamber 101 is fixedly connected to the outer wall of the base 1. A solenoid valve 6 is provided on the air pipe 5. The end of the air pipe 5 away from the first vacuum adsorption chamber 101 is connected to the vacuum generator. In use, the FPC / FFC ribbon cable terminal is placed in the contour positioning groove 401 of the carrier 4 for initial positioning and fixation. Then, the vacuum generator works and the solenoid valve 6 is opened to evacuate the first vacuum adsorption chamber 101 and the second vacuum adsorption chamber 403. A suction force is generated at the vacuum adsorption hole 402, thereby adsorbing and fixing the FPC / FFC ribbon cable terminal in the contour positioning groove 401. This ensures that the FPC / FFC ribbon cable terminal is tightly attached to the contour positioning groove 401, ensuring that the FPC / FFC ribbon cable terminal is flat at the crimping position. This avoids the relative displacement of the FPC / FFC ribbon cable terminal during the clamping process of the clamping mechanism, which could cause problems such as ribbon cable crimping offset or abnormal length.

[0027] In this embodiment, as Figure 4 As shown, the bottom of the base 1 is provided with a first sealing groove outside the first vacuum adsorption chamber 101, and a first sealing ring 11 is installed in the first sealing groove. The first sealing ring 11 improves the sealing between the base 1 and the base plate 2, thereby ensuring the sealing of the first vacuum adsorption chamber 101. The bottom of the carrier 4 is provided with a second sealing groove outside the second vacuum adsorption chamber 403, and a second sealing ring 12 is installed in the second sealing groove. The second sealing ring 12 improves the sealing between the carrier 4 and the base 1, thereby ensuring the sealing of the second vacuum adsorption chamber 403.

[0028] In this embodiment, as Figure 3 and Figure 4As shown, the locking and positioning structure includes four rectangularly distributed guide posts 9 fixedly connected to the bottom of the carrier 4 and four guide sleeves 10 embedded in the base 1. The guide sleeves 10 correspond one-to-one with the guide posts 9, and the guide posts 9 are inserted into the guide sleeves 10. The locking and positioning structure also includes threaded posts 7 fixedly connected to both sides of the bottom of the carrier 4. The base 1 has a first through hole 103 corresponding to the position of the threaded post 7, and the base plate 2 has a second through hole 201 corresponding to the position of the threaded post 7. The bottom end of the threaded post 7 passes through the first through hole 103 and the second through hole 201 and is threadedly connected to a locking nut 8. The locking nut 8 is pressed against the bottom of the base plate 2. When the carrier 4 is assembled with the base 1 and the base plate 2, the carrier 4 is... The guide post 9 is inserted into the guide sleeve 10 on the base 1 to ensure the accuracy of the assembly and alignment of the carrier 4 and the base 1. The threaded post 7 is aligned and passes through the first through hole 103 and the second through hole 201. It is connected to the threaded post 7 by the locking nut 8. The locking nut 8 is pressed against the bottom of the base plate 2 to install and fix the carrier 4 and the base 1. It can also press the carrier 4 towards the base 1, which is convenient for disassembly and replacement of the carrier 4 to replace the contour positioning groove 401 of different shapes. It is suitable for positioning and fixing FPC / FFC ribbon cable terminals of different specifications, improving applicability. It should be noted that even if the carrier 4 of different specifications is replaced, the through groove 102 must be placed inside the second vacuum adsorption chamber 403 of the carrier 4.

[0029] In this embodiment, as Figure 3 As shown, extension plates 404 are fixedly connected to both sides of the vehicle 4. The extension plates 404 are integrally formed with the vehicle 4. The extension plates 404 extend to the outside of the base 1 and the bottom plate 2. The extension plates 404 act as handles, making it easy to hold the extension plates 404 and move the vehicle 4.

[0030] In this embodiment, as Figure 1 As shown, mounting plates 3 are fixedly connected to both sides of the base plate 2. The mounting plates 3 are fixed to the base plate 2 by welding or integral casting. The mounting plates 3 have fixing holes. The mounting plates 3 form an operating space under the base plate 2, which facilitates the connection and disassembly of the locking nuts 8. The mounting plates 3 are fixed in the use position by passing the fixing bolts through the fixing holes.

[0031] Working principle: During use, the FPC / FFC ribbon cable terminal is initially positioned and fixed in the contour positioning groove 401 of the carrier 4. Then, the vacuum generator operates, and the solenoid valve 6 is opened, evacuating the first vacuum adsorption chamber 101 and the second vacuum adsorption chamber 403. Suction is generated at the vacuum adsorption hole 402, thereby adsorbing and fixing the FPC / FFC ribbon cable terminal in the contour positioning groove 401. This ensures the flatness of the FPC / FFC ribbon cable terminal at the crimping position and prevents relative displacement of the FPC / FFC ribbon cable terminal during the clamping process, which could cause crimping misalignment or abnormal length. When changing the carrier 4, the locking nut 8 is removed. Then, by moving the carrier 4 upward through the extension plate 404, the carrier 4 can be disassembled and separated from the base 1. Then, the new carrier 4 is assembled with the base 1 and the base plate 2. The guide post 9 on the carrier 4 is aligned and inserted into the guide sleeve 10 on the base 1 to ensure the accuracy of the alignment between the carrier 4 and the base 1. The threaded post 7 is aligned and passes through the first through hole 103 and the second through hole 201. It is connected to the threaded post 7 by the locking nut 8. The locking nut 8 is pressed against the bottom of the base plate 2 to install and fix the carrier 4 and the base 1. This facilitates the disassembly and replacement of the carrier 4 to replace the contour positioning groove 401 of different shapes. It is suitable for positioning and fixing FPC / FFC ribbon cable terminals of different specifications, thus improving applicability.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
