Abstract
Description
Technical Field
[0001] This application relates to the field of strip unloading, and in particular to a jig for strip unloading. Background Technology
[0002] During the operation of electrical equipment, electrical connections are often made through connectors. A connector consists of a connector head and several pins 4, which are fixedly connected to one end of the connector head to facilitate electrical connection.
[0003] In existing related technologies, refer to Figure 1 To facilitate manufacturing, transportation, and sales, the PIN pin 4 is usually integrated with the scrap section 5 as a strip. Therefore, when using the PIN pin 4 to produce connectors, workers need to use tools to remove the strip so that the PIN pin 4 can be removed from the scrap section 5.
[0004] Regarding the aforementioned technologies, when workers are stripping materials, the PIN pin 4 is thin and soft, making it easy for workers to bend it with their hands or tools, thus damaging the PIN pin 4. Summary of the Invention
[0005] In order to reduce the damage to the pins during the strip unloading process, this application provides a jig for strip unloading.
[0006] The jig for stripping material provided in this application adopts the following technical solution:
[0007] A jig for strip unloading includes a jig base, a stripping punch, and a punch drive. The jig base has a strip groove for placing the strip, and the outline of the strip groove corresponds to the outline of the strip.
[0008] The stripping punch is located at the top of the strip trough. The stripping punch includes a punch mounting block, a strip pressing block, and a punch body. The strip pressing block is elastically connected to the punch mounting block in the vertical direction. The punch body is mounted on the punch mounting block. The punch driving component is used to move the punch mounting block in the vertical direction.
[0009] When stripping material, the punch body will press against the waste part of the strip, and the strip pressing block will contact the strip before the punch body.
[0010] By adopting the above technical solution, when stripping the material, the material is placed in the strip trough to prevent it from shaking. Then, the stripping punch is driven by the punch drive to move the strip vertically towards the strip. When the stripping punch approaches the strip, the strip clamping block first presses against the strip, and then the punch body presses against the waste section of the strip. This prevents the pins of the strip from bending or sticking out during the removal of the waste section, thereby reducing the possibility of damage to the pins during the stripping process.
[0011] Optionally, the punch mounting block has a pressure block groove inside, and the material strip pressure block slides vertically to engage with the pressure block groove.
[0012] By adopting the above technical solution, it is beneficial to improve the stability of the material strip block when it moves in the vertical direction and reduce the occurrence of poor limiting conditions caused by the shaking of the material strip block.
[0013] Optionally, the material strip pressing block is provided with a punch guide groove, the punch body is located inside the pressing block groove, and the punch body is attached to the inner wall of the pressing block groove.
[0014] By adopting the above technical solution, it is beneficial to further improve the stability of the material strip block when it moves in the vertical direction and reduce the occurrence of poor limiting conditions caused by the shaking of the material strip block.
[0015] Optionally, the strip pressing block and the punch mounting block are elastically connected by a linear spring, with the two ends of the linear spring respectively mounted on the strip pressing block and the punch mounting block, and the linear spring is arranged in the vertical direction.
[0016] By adopting the above technical solution, the material strip pressing block can be stably reset by a linear spring after it moves away from the material strip.
[0017] Optionally, the fixture base is provided with a limiting strip, which slides horizontally to engage with the fixture base;
[0018] When unloading the material strip, the limiting strip is located at the top of the material strip groove and is attached to the top of the material strip.
[0019] By adopting the above technical solution, when stripping material, the limiting strip is pushed horizontally so that it moves to the top of the strip. This makes it less likely for the end of the strip to lift up, thus facilitating the PIN needle to be punched out of the waste section and reducing the generation of burrs on the punching surface.
[0020] Optionally, the punch drive component is a cylinder.
[0021] By adopting the above technical solution, it is beneficial to improve the response speed of the punch drive component.
[0022] Optionally, the punch body is mounted to the punch mounting block by bolts.
[0023] By adopting the above technical solution, it is convenient to replace the punch body according to the specifications of the material strip.
[0024] Optionally, the fixture base is provided with a punch slider, the punch slider slides vertically and engages with the fixture base, the punch drive unit moves the punch mounting block vertically through the punch slider, and the punch mounting block is adjustablely mounted on the punch slider horizontally.
[0025] By adopting the above technical solution, it is easy to adjust the punching position of the punch body according to the specifications of the strip, thereby ensuring the stripping accuracy.
[0026] Optionally, the punch mounting block has a punch adjustment hole extending horizontally, and the punch mounting block is mounted on the punch slider by an adjustment bolt passing through the punch adjustment hole.
[0027] By adopting the above technical solution, when it is necessary to adjust the punching position of the punch body, simply loosen the adjusting bolt and let the punch mounting block slide horizontally to align with the material strip, which is convenient and quick.
[0028] Optionally, the fixture body is provided with a material picking groove, which extends horizontally toward the location of the material strip groove;
[0029] The material picking chute is slidably fitted with a needle picking component, which has a plurality of needle picking holes, each of which is used to insert a PIN pin of the material strip.
[0030] By adopting the above technical solution, workers can easily remove all the pins at once after unloading, which helps to improve work efficiency.
[0031] In summary, this application includes at least one of the following beneficial technical effects:
[0032] 1. When stripping the material strip, place the strip in the strip trough to prevent it from shaking. Then, use the punch drive to move the stripping punch vertically towards the strip. As the stripping punch approaches the strip, the strip clamping block first presses against the strip, and then the punch body presses against the scrap section of the strip. This prevents the pins of the strip from bending or sticking up during the scrap removal process, thus reducing the chance of damage to the pins during stripping.
[0033] 2. When stripping, push the limiting strip horizontally so that the limiting strip moves to the top of the strip. This will prevent the end of the strip from lifting up, making it easier to punch the PIN pins off from the waste section and reducing the generation of burrs on the punched surface.
[0034] 3. It facilitates the adjustment of the punch body's cutting position according to the specifications of the strip, thereby ensuring the stripping accuracy. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0045] Example 1:
[0046] Embodiment 1 of this application discloses a jig for stripping material from a conveyor belt. (Refer to...) Figure 2 The jig used for stripping material includes a jig base 1, a stripping punch 2, and a punch drive 3.
[0047] Reference Figure 2The fixture base 1 is provided with a punch slider 11, which slides vertically and engages with the fixture base 1. The punch drive 3 is a cylinder, and the cylinder body of the punch drive 3 is fixedly installed on the fixture base 1. The piston rod of the punch drive 3 is fixedly installed on the punch slider 11 so that the punch slider 11 can be moved vertically by the punch drive 3.
[0048] Reference Figure 2 and Figure 3 The stripping punch 2 includes a punch mounting block 21, a strip pressing block 22, and a punch body 23. The punch mounting block 21 is fixedly mounted on the punch slider 11 so that the stripping punch 2 can be driven to move vertically by the punch drive 3. Figure 4 The punch mounting block 21 has a pressure block groove 201 inside, which extends vertically downwards. The strip pressure block 22 slides vertically within the pressure block groove 201, and its outer wall fits against the inner wall of the groove, allowing it to move stably vertically within the groove. Two linear springs 211 are installed inside the pressure block groove 201, distributed horizontally. The linear springs 211 are vertically positioned, with their ends fixed to the inner wall of the groove and the strip pressure block 22, respectively. This allows the strip pressure block 22 to elastically connect to the punch mounting block 21 vertically, facilitating its extension and reset after contacting the fixture seat 1.
[0049] Reference Figure 4 The strip pressing block 22 has a punch guide groove 202, which extends vertically upwards and downwards. The top of the punch body 23 is fixedly mounted to the punch mounting block 21 by bolts (not shown in the figure), and the punch body 23 is located inside the punch guide groove 202. The outer circumferential surface of the punch body 23 is in contact with the inner wall of the punch guide groove 202, so as to further ensure that the strip pressing block 22 moves stably in the vertical direction. In addition, when the strip pressing block 22 is not retracted into the pressing block groove 201, the bottom end of the punch body 23 is located inside the punch guide groove 202. Furthermore, when the strip pressing block 22 retracts into the pressing block groove 201, the bottom end of the punch body 23 is located outside the punch guide groove 202, so that when stripping the strip, the punch body 23 presses against the waste part 5 of the strip, and the strip pressing block 22 contacts the strip before the punch body 23, thereby making the strip less likely to bend or lift under the action of the punch body 23.
[0050] Reference Figure 5The fixture body 1 has a strip groove 101 located at the bottom of the punch body 23. The strip groove 101 is used to hold the strip. The outline of the strip groove 101 corresponds to the outline of the strip; that is, after the strip is placed in the strip groove 101, the pins 4 and scrap parts 5 of the strip are closely fitted against the inner wall of the strip groove 101, making it less likely for the strip to wobble within the strip groove 101. Figure 1 In this embodiment, the strip groove 101 is used to hold the strip with six pins 4. In addition, a waste trough is provided through the bottom of the fixture body 1, and the waste trough is connected to the strip groove 101 so that the waste part 5 can fall into the waste trough after unloading.
[0051] The fixture base 1 is provided with a limiting strip 12. The limiting strip 12 slides horizontally and engages with the fixture base 1 through a through hole, so that when the strip is unloaded, the limiting strip 12 slides to the top of the strip groove 101 and adheres to the top of the strip, making it easier for the strip to lift up.
[0052] Reference Figure 5 and Figure 6 The jig base 1 has a material-retrieving chute 102 on the side facing the worker, extending horizontally towards the location of the material strip groove 101. A needle-retrieving component 13 is slidably fitted into the material-retrieving chute 102, and the needle-retrieving component is detachably disposed within the material-retrieving chute 102. The needle-retrieving component 13 has several needle-retrieving holes 131, each used to insert a PIN needle 4 from the material strip, allowing the worker to remove all PIN needles 4 at once after unloading, thereby improving work efficiency. Furthermore, in this embodiment, the needle-retrieving holes 131 are arranged in two sets, upper and lower, respectively, for retrieving PIN needles 4 of different specifications, thus improving the applicability of the needle-retrieving component 13.
[0053] The implementation principle of a jig for strip unloading in Embodiment 1 of this application is as follows: When unloading the strip, the strip is placed in the strip groove 101, and then the limiting strip 12 is pushed towards the location of the strip to prevent the strip from shaking. Then, the punch drive 3 causes the unloading punch 2 to approach the strip vertically, thereby causing the pin 4 to separate from the waste part 5. The pin 4 remains in the strip groove 101, and the waste part 5 falls into the waste trough. Finally, the pin take-up member 13 is placed in the take-up slide 102 and then pushed towards the location of the pin 4, so that all the pins 4 are transferred into the pin take-up member 13, thereby reducing the occurrence of the pins 4 bending due to worker contact. When the stripping punch 2 approaches the strip, the strip clamping block 22 first presses against the strip, and then the punch body 23 presses against the waste section 5 of the strip, so that the pins 4 of the strip are not easily bent or lifted during the process of removing the waste section 5, thereby reducing the damage of the pins 4 during the stripping process.
[0054] Example 2:
[0055] Embodiment 2 of this application discloses a jig for strip unloading, which differs from Embodiment 1 in that the fitting relationship between the punch mounting block 21 and the punch slider 11 is different.
[0056] Reference Figure 7 The punch slide block 11 has a mounting block groove 111 extending horizontally. The punch mounting block 21 is slidably fitted into the mounting block groove 111 in the horizontal direction to adjust the position of the punch mounting block 21 and the punch body 23, thereby aligning the punch body 23 with the material strip in the strip groove 101. The punch mounting block 21 has a punch adjustment hole 203 extending horizontally. The punch mounting block 21 is mounted on the punch slide block 11 by an adjustment bolt 212 passing through the punch adjustment hole 203. This allows the punch mounting block 21 to be securely mounted on the punch slide block 11 by tightening the adjustment bolt 212, or to be adjusted horizontally by loosening the adjustment bolt 212.
[0057] The implementation principle of a jig for strip unloading in Embodiment 2 of this application is as follows: after changing the specifications of the punch body 23, the specifications of the strip, or after the jig ages, the direction of the punch body 23 can be adjusted in the horizontal direction, thereby improving the applicability and durability of the punch body 23.
[0058] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
