Description

Technical Field

[0001] This utility model belongs to the field of terminal placement rack technology, and in particular relates to a terminal placement rack for automotive wiring harness production. Background Technology

[0002] In electrical engineering, terminals often refer to wiring terminals, also called wire terminals. Their main function is to transmit electrical signals or conduct electricity. Therefore, in the production process of automotive wiring harnesses, terminals need to be connected to plastic bodies and wires. Terminals are generally adhered in an orderly manner to a strip to form a long strip of terminal material. This terminal material strip is then rolled into a turntable of a roller to form a terminal tray. This terminal tray is then placed on the feeding rack of a terminal pressing machine. After that, the end of the terminal material strip is pulled to separate the terminal strip from the adhered paper strip, and then the end of the terminal strip is pressed into the terminal pressing die of the terminal pressing machine, thus realizing the feeding of terminals.

[0003] Chinese patent CN217597066U discloses a terminal placement rack for automotive wiring harness production. The patent states that it "includes a frame, on which a terminal tray placement area and a terminal mold placement area are provided. The number of terminal tray placement areas and terminal mold placement areas are the same. The terminal tray placement area includes a first limiting mechanism to restrict the rolling of the terminal tray and a second limiting mechanism to restrict the tilting of the terminal tray. The terminal mold placement area includes a horizontally arranged shelf. This rack has both terminal tray placement areas and terminal mold placement areas, and the number of both is the same. Terminal molds corresponding to the terminal trays can be placed on adjacent shelf panels, facilitating simultaneous access to the terminal trays and corresponding terminal molds, effectively improving production efficiency."

[0004] However, in the above solution, the vertical support can only hold one terminal plate at a time. When a terminal plate is used up, it needs to be removed from the vertical support and then replaced with a new terminal plate. Therefore, the process of replacing the terminal plate increases the labor time of workers. Most of the terminal plate placement racks commonly found on the market are simply for placement, with a relatively small number of terminal plates that can be placed. They are also not easy to pick up and can easily deform the terminals if not handled carefully. Therefore, it is necessary to design a terminal placement rack for automotive wiring harness production. Utility Model Content

[0005] This utility model provides a terminal placement rack for automotive wiring harness production, which aims to solve the problems of a small number of terminal trays that are difficult to handle and can easily deform if not handled carefully.

[0006] This utility model is implemented as follows: a terminal placement rack for automotive wiring harness production includes a frame and a terminal tray; connecting trays are mounted on the upper and lower sides of the frame; a mounting cylinder is fixed to one side of the connecting tray; limiting blocks arranged in a horizontal array are fixed to both sides of the inner cavity of the mounting cylinder; a synchronization plate is slidably connected to the surface of the limiting blocks; a locking plate arranged in a horizontal array is fixed to one side of the synchronization plate; the locking plate has protruding teeth on its outer side; and tension springs are fixed to both sides of the synchronization plate; an unlocking mechanism is mounted on the other side of the synchronization plate, used to retract the locking plate to remove the terminal tray from the mounting cylinder; two guard plates are fixedly mounted on one side of the frame; a first synchronous electric cylinder is fixedly mounted on the top of the guard plate; and a second synchronous electric cylinder is mounted on the bottom of the guard plate and the bottom of the frame; the extension end of the first synchronous electric cylinder is fixedly mounted with a lower arc-shaped support plate, and the extension end of the second synchronous electric cylinder is fixedly mounted with an upper arc-shaped pressure plate; and a rotation limiting mechanism is fixedly mounted on one side of the connecting tray, used to limit the feeding rotation of the connecting tray and the terminal tray.

[0007] Preferably, the unlocking mechanism includes: multiple sets of connecting seats fixedly connected to one side of the synchronization plate, and multiple... The inner side of each connecting seat is rotatably connected to a connecting rod. A through groove is opened in the middle of the connecting rod. An unlocking rod is slidably sleeved on the inner side of the through groove. One end of the unlocking rod passes through the mounting cylinder and is bolted to a pressing piece.

[0008] Preferably, the rotation limiting mechanism includes: a connecting shaft seat fixedly mounted on the back of the connecting disc. The other side of the connecting shaft seat is rotatably connected to the outer wall of the frame. The inner sides of the connecting shaft seat and the connecting plate are provided with limiting holes arranged in a ring array. The inner side of the limiting holes is slidably connected with a plug rod, and the middle of the plug rod is fixed with a limiting ring.

[0009] Preferably, a rectangular groove is formed in the middle of the terminal block, and the side shape of the mounting cylinder is the same as that of the rectangular groove.

[0010] Preferably, locking grooves are provided on both sides of the inner cavity of the terminal block, and the locking grooves have the same shape as the protruding teeth.

[0011] Preferably, the mounting cylinder has horizontally arrayed shrinkage grooves on both sides, and the locking plate and the interior of the shrinkage grooves form an insertion structure.

[0012] Preferably, both the lower arc-shaped support plate and the upper arc-shaped pressure plate have arc-shaped grooves inside, and the arc-shaped grooves and the outer wall of the terminal block form a sleeve structure.

[0013] Preferably, the two connecting rods have the same shape and are fixed to the upper and lower sides of the unlocking rod, respectively.

[0014] Compared with related technologies, the terminal placement rack for automotive wiring harness production provided by this utility model has the following advantages: By manually pushing the unlocking lever into the inner cavity of the mounting cylinder, the connecting rods on both sides move the synchronous plates connected to them in opposite directions, causing the locking plates on both sides to retract into the mounting cylinder. The locking plates move into the retraction grooves, and through the synchronous drive of the unlocking lever, the outer wall of the mounting cylinder is no longer obstructed by the locking plates. The terminal plate can then be inserted through the rectangular groove on its inner side into the outer side of the mounting cylinder. Pushing the terminal plate to the desired fixing position and releasing the unlocking lever allows the tension spring to push the locking plate back to its original position, so that the protruding teeth on the outer side of the locking plate insert into the locking groove to complete the fixing. The synchronous locking or unlocking method makes installation convenient and facilitates quick loading and replacement of the terminal plate.

[0015] By controlling the first and second synchronous electric cylinders on the upper and lower sides, after the terminal plate on the mounting cylinder is pushed to the fixed position and locked, the first synchronous electric cylinder is first activated, causing it to push the lower arc-shaped support plate at the corresponding position on the bottom of the terminal plate upward. Since the cavity on the inner side of the lower arc-shaped support plate has the same shape as the outer wall of the terminal plate, the terminal plate is inserted into the lower arc-shaped support plate. Then, the second synchronous electric cylinder pushes the upper arc-shaped pressure plate at the corresponding position, so that the upper and lower arc-shaped plates respectively position the terminal plate longitudinally. After the terminal plates are arranged and installed, the terminal plates on the mounting cylinder are parallel to each other and do not contact each other, avoiding damage caused by collision due to rotation and shaking during the rotating feeding process. It also prevents the terminal plates from falling off the surface of the mounting cylinder, improving the safety of the terminal plates in use. Attached Figure Description

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. Example 1

[0020] A preferred embodiment of the terminal placement rack for automotive wiring harness production provided by this utility model is, for example... Figures 1 to 5As shown: A terminal placement rack for automotive wiring harness production includes a frame body 1 and a terminal plate 2; connecting plates 3 are mounted on the upper and lower sides of the frame body 1, a mounting cylinder 4 is fixedly connected to one side of the connecting plate 3, and limiting blocks 5 arranged in a horizontal array are fixedly connected to both sides of the inner cavity of the mounting cylinder 4. A synchronization plate 6 is slidably connected to the surface of the limiting block 5, and a locking plate 7 arranged in a horizontal array is fixedly connected to one side of the synchronization plate 6. The outer side of the locking plate 7 is provided with protruding teeth 8, and tension springs 9 are fixedly connected to both sides of the synchronization plate 6; an unlocking mechanism 10 is mounted on the other side of the synchronization plate 6, and the unlocking mechanism 10 is used to retract the locking plate 7 to remove the terminal plate 2 from the mounting cylinder 4; two guard plates 11 are fixedly installed on one side of the frame body 1, a first synchronous electric cylinder 12 is fixedly connected to the top of the guard plate 11, and a second synchronous electric cylinder 13 is mounted on the bottom of the guard plate 11 and the bottom of the frame body 1. A lower arc-shaped support plate 14 is fixedly connected to the telescopic end of the first synchronous electric cylinder 12, and an upper arc-shaped pressure plate 15 is fixedly connected to the telescopic end of the second synchronous electric cylinder 13. A rotation limiting mechanism 16 is fixedly installed on one side of the connecting plate 3. The rotation limiting mechanism 16 is used to limit the feeding rotation of the connecting plate 3 and the terminal plate 2.

[0021] It should be noted that some existing terminal placement racks used in automotive wiring harness production still have certain shortcomings in actual use. In the comparison documents, during use, the process of replacing terminal plate 2 increases the worker's labor time, the number of terminal plates 2 placed is relatively small, and they are not easy to pick up. Furthermore, slight negligence can cause the terminals to deform.

[0022] In this embodiment, during the installation of the terminal block 2, the unlocking lever 104 is first manually pushed into the inner cavity of the mounting cylinder 4, causing the connecting rods 102 on both sides to move towards each other, i.e., causing the locking plates 7 on both sides to retract into the mounting cylinder 4, so that the locking plates 7 move into the retraction groove 18. Through the synchronous drive of the unlocking lever 104, the outer wall of the mounting cylinder 4 is no longer blocked by the locking plates 7, and the terminal block 2 can be inserted into the outer side of the mounting cylinder 4 through the rectangular groove on its inner side. The terminal block 2 is pushed to the desired fixing position, and the unlocking lever 104 is released. The spring force of the tension spring 9 pushes the locking plate 7 to reset, so that the protruding teeth 8 on the outer side of the locking plate 7 are inserted into the locking groove 17 to complete the fixing. Then the second opening is activated. A first synchronous electric cylinder 12 pushes the lower arc-shaped support plate 14 at the corresponding position on the bottom of the terminal plate 2 upward. Since the cavity on the inner side of the lower arc-shaped support plate 14 has the same shape as the outer wall of the terminal plate 2, the terminal plate 2 is inserted into the lower arc-shaped support plate 14. Then, the second synchronous electric cylinder 13 pushes the upper arc-shaped pressure plate 15 at the corresponding position, so that the upper and lower arc-shaped plates respectively position the terminal plate 2 longitudinally. After the terminal plates 2 are arranged and installed, the terminal plates 2 on the mounting cylinder 4 are parallel to each other and do not contact each other, which avoids the terminal plates 2 from colliding and being damaged due to rotation and shaking during the rotation feeding process. At the same time, it can also prevent the terminal plates 2 from falling off the surface of the mounting cylinder 4, thus improving the safety of the terminal plates 2 in use.

[0023] In a further preferred embodiment of the present invention, a rectangular groove is provided in the middle of the terminal block 2, and the side shape of the mounting cylinder 4 is the same as that of the rectangular groove.

[0024] In this embodiment, the rectangular groove has the same shape as the side cross-section of the mounting cylinder 4, but the inner diameter of the rectangular groove is larger than the side cross-section of the mounting cylinder 4. This design allows the terminal plate 2 to pass through the rectangular groove through the mounting cylinder 4 and slide on its surface, while retaining a certain amount of space to reduce the friction generated during its sliding process.

[0025] In a further preferred embodiment of the present invention, locking grooves 17 are provided on both sides of the inner cavity of the terminal plate 2, and the locking grooves 17 have the same shape as the protruding teeth 8.

[0026] In this embodiment, the locking plate 7 can lock the terminal plate 2 in the horizontal direction by using the locking groove 17 and the protruding tooth 8 to lock each other in a mutually locking manner.

[0027] In a further preferred embodiment of the present invention, the mounting cylinder 4 has horizontally arrayed shrinkage grooves 18 on both sides, and the locking plate 7 and the interior of the shrinkage grooves 18 form an insertion structure.

[0028] In this embodiment, the locking plate 7 can enter the shrinkage groove 18 when it retracts into the mounting cylinder 4.

[0029] Example 2 Based on Embodiment 1, a preferred embodiment of the terminal placement rack for automotive wiring harness production provided by this utility model is, for example... Figures 1 to 5 As shown: The unlocking mechanism 10 includes: a fixed connection to Multiple sets of connecting seats 101 are located on one side of the synchronization plate 6. Each set of connecting seats 101 is rotatably connected to a connecting rod 102. A through groove 103 is provided in the middle of the connecting rod 102. An unlocking rod 104 is slidably sleeved on the inner side of the through groove 103. One end of the unlocking rod 104 passes through the mounting cylinder 4 and is bolted to a pressing piece 105.

[0030] In this embodiment, one end of the connecting rod 102 is fixed to one side of the synchronous plate 6 using the connecting seat 101. Then, the horizontal movement of the unlocking rod 104 causes the connecting rods 102 on both sides of its surface to move synchronously, and the synchronous plates 6 on both sides are pushed to expand to the sides or contract inwards by shearing force. In a further preferred embodiment of this utility model, the rotation limiting mechanism 16 includes: fixedly installed... The connecting shaft seat 161 on the back of the connecting plate 3 is rotatably connected to the outer wall of the frame 1 on the other side. Both the connecting shaft seat 161 and the inner side of the connecting plate 3 are provided with limiting holes 162 arranged in a ring array. The inner side of the limiting hole 162 is slidably connected with the insertion rod 163, and the middle part of the insertion rod 163 is fixedly connected with the limiting ring 164.

[0031] In this embodiment, the connecting plate 3 is connected to the outer wall of the frame 1 using the connecting shaft seat 161. At the same time, the bidirectional opening allows the insertion rod 163 to pass through the limiting hole 162 through the connecting shaft seat 161 and the connecting plate 3, thereby limiting its rotation and preventing the terminal plate 2 from continuing to rotate during non-working periods.

[0032] In a further preferred embodiment of the present invention, both the lower arc-shaped support plate 14 and the upper arc-shaped pressure plate 15 are provided with arc-shaped grooves inside, and the arc-shaped grooves and the outer side wall of the terminal block 2 form a sleeve structure.

[0033] In this embodiment, by utilizing the arc-shaped groove cavity structure corresponding to the outer wall of the terminal plate 2, the lower arc-shaped support plate 14 and the upper arc-shaped pressure plate 15 can simultaneously limit the position of the terminal plate 2.

[0034] In a further preferred embodiment of this utility model, the connecting rods 102 on both sides have the same shape and are respectively fixed on the upper and lower sides of the unlocking rod 104.

[0035] In this embodiment, the unlocking lever 104 drives the connecting rod 102 to push and pull the synchronization plates 6 on both sides simultaneously, providing driving force to the synchronization plates 6.

[0036] In summary, the synchronous locking or unlocking method facilitates installation, enabling quick feeding and replacement of the terminal blocks 2. The terminal blocks 2 on the mounting cylinder 4 are parallel to each other and do not contact each other, preventing damage caused by collisions due to rotation and shaking during the feeding process. It also prevents the terminal blocks 2 from falling off the surface of the mounting cylinder 4, thus improving the safety of the terminal blocks 2 in use.
