Description

Technical Field

[0001] This utility model relates to the field of circuit board processing equipment technology, and in particular to a pin bending and installation device. Background Technology

[0002] Circuit boards typically have connectors with multiple pins. The circuit board has connection holes, and the pins pass through the connection holes from one side of the circuit board to the other side. The cross-section of the pins is usually flat or irregular. The operator needs to use pliers to hold the pins and apply force to make them rotate and bend, so that the pins cannot come out of the connection holes after deformation, ensuring the connection stability between the connector and the circuit board. Then the pins are soldered to the circuit board.

[0003] However, the process of bending the pins one by one is slow, and the force applied to different pins each time results in different bending degrees, which leads to different deformation and different connection tightness of the pins. If the processing personnel apply too much force to bend the pins, it may also cause damage to the pins or subsequent poor contact. Utility Model Content

[0029] like Figures 1 to 6 As shown, a pin 530 bending and mounting device according to a first aspect embodiment of the present invention includes a base frame 100, a bending assembly 200, and a drive module 400. The base frame 100 is provided with a fixed station 110 for placing and fixing a circuit board 500. The bending assembly 200 includes a plurality of bending ends 210, which are rotatably mounted on the base frame 100. Each bending end 210 is provided with a limiting slot 220, into which a pin 530 at the upper end of the circuit board 500 can be inserted, and the limiting slot 220 can limit the rotation of the pin 530. The drive module 400 is disposed on the base frame 100 and is connected to each of the bending ends 210 to drive each of the bending ends 210 to rotate.

[0030] It should be noted that, for example Figure 2 , 3As shown, the circuit board 500 is provided with a connection terminal 510. The connection terminal 510 is provided with a conductor for connecting with external signal transmission lines, wires, core wires or conductive busbars and other components. The connection terminal 510 is provided with multiple pins 530, which are electrically connected to the conductor. The circuit board 500 is provided with a connection hole 520. The pins 530 pass through the connection hole 520 from one side of the circuit board 500 and protrude from the other side. The cross-section of the pins 530 is generally flat or irregularly shaped. After driving the pins 530 to rotate and bend, the pins 530 cannot come out of the connection hole 520, thus realizing the connection between the connection terminal 510 and the circuit board 500.

[0031] The base frame 100 can be made of metal or alloy materials, or connected by sheet metal. The drive module 400 can be equipped with an electrical control device. After the processing worker applies the electrical control command, it automatically executes the bending action to drive the pin 530 to bend. Alternatively, the drive module 400 can only be equipped with a transmission structure and a driven component 410 that allows the processing worker to manually apply force. The processing worker applies force to drive the bending end 210 to rotate, so that the pin 530 is bent.

[0032] This utility model relates to a pin 530 bending and mounting device. A processing operator can place a circuit board 500 on a fixed station 110, which secures the circuit board 500. The pins 530 at the ends of the circuit board 500 that need to be bent are correspondingly inserted into the limiting slots 220. The processing operator operates a drive module 400, which drives each bending end 210 to rotate. As the bending ends 210 rotate, the limiting slots 220 subsequently cause the pins 530 to rotate and be bent. With a single operation, multiple pins 530 on the circuit board 500 can be bent to approximately equal bending angles. This design improves processing efficiency, saves processing time, and ensures a high yield rate for finished products.

[0033] In some embodiments of this utility model, such as Figure 4 As shown, the fixed workstation 110 includes a support plate 130 disposed on the base frame 100 and a limiting member 140 disposed on the base frame 100. The limiting member 140 defines a placement area on the surface of the support plate 130. The support plate 130 is provided with a plurality of insertion holes 120 in the placement area. Some of the insertion holes 120 allow the pins 530 to pass through, and some of the insertion holes 120 are provided with the twisted end 210.

[0034] The circuit board 500 can be placed on the support plate 130, and the limiting member 140 abuts against the side of the circuit board 500, thereby limiting the horizontal displacement of the circuit board 500 and ensuring that the pins 530 are not easily damaged during the bending process. It is understood that there are multiple pins 530 on the connection end 510, and not all pins 530 need to be bent. Therefore, the pins 530 that need to be bent are inserted into the limiting slots 220 on the bending end 210 one by one, while the pins 530 that do not need to be bent can pass through the insertion holes 120 where the bending end 210 is not provided to avoid damage, ensuring that the pins 530 that do not need to be bent are not easily damaged during the bending process.

[0035] In some embodiments of this utility model, such as Figure 1 , 4 As shown, there are multiple limiting members 140, and the multiple limiting members 140 define a fixing groove to form a placement area.

[0036] Specifically, the limiting member 140 can be a protruding rib provided on the surface of the bearing plate 130. According to the specific shape of the circuit board 500, the number of limiting members 140 corresponding to the side of the circuit board 500 can be set to enclose a placement area that matches the shape of the circuit board 500. The circuit board 500 is placed in the placement area, and multiple limiting members 140 abut against the side of the circuit board 500 one by one to limit the position of the circuit board 500.

[0037] In some embodiments of this utility model, such as Figure 4 As shown, the pin 530 bending and mounting device also includes a stationary end 300, which is fixedly disposed on the base frame 100 and passes through the insertion hole 120. The stationary end 300 is provided with an auxiliary slot 310, in which some pins 530 can be inserted and the auxiliary slot 310 can limit the rotation of the pins 530.

[0038] For some pins 530 that do not require bending, they can be inserted into the auxiliary slot 310 after passing through the insertion hole 120. During the bending process of some pins 530, the stationary end 300 will not rotate relative to the base shell. The pins 530 inserted into the auxiliary slot 310 play an auxiliary positioning role, which can limit the sway of the circuit board 500 and the connection end 510 and improve the bending effect of the pins 530.

[0039] In some embodiments of this utility model, such as Figure 5 , 6As shown, the drive module 400 includes a driven component 410 and a transmission assembly 420. The transmission assembly 420 is disposed on the base frame 100 and is connected to a plurality of bending ends 210 respectively. The driven component 410 is connected to the transmission assembly 420. Applying force to the driven component 410 can cause the plurality of bending ends 210 to rotate synchronously.

[0040] The operator operates on the driven part 410, which can drive multiple bending ends 210 to rotate synchronously through the transmission component 420, thereby enabling multiple pins 530 to bend synchronously, ensuring that the bending amplitude is approximately the same and improving the bending effect.

[0041] In some embodiments of this utility model, such as Figure 5 , 6 As shown, the transmission assembly 420 includes a main drive mechanism 430 and a plurality of driven shafts 440. The main drive mechanism 430 is disposed on the base frame 100. The driven member 410 is connected to the main drive mechanism 430. The plurality of driven shafts 440 are connected to the bending end 210 in a one-to-one correspondence. The main drive mechanism 430 is connected to each of the driven shafts 440 respectively so as to drive each of the driven shafts 440 to rotate synchronously.

[0042] Each twisted end 210 is driven by a driven shaft 440, while the main drive mechanism 430 is connected to multiple driven shafts 440 respectively, so that the twisted end 210 can be driven to rotate synchronously by multiple driven shafts 440.

[0043] Specifically, the main drive mechanism 430 includes a first gear 431, a second gear 432, and a plurality of driven gears 433. The driven member 410 is connected to the first gear 431 to drive the first gear 431 to rotate. The first gear 431 and the second gear 432 mesh. The second gear 432 is connected to any one of the driven shafts 440. The plurality of driven gears 433 are connected to the driven shafts 440 in a one-to-one correspondence. Adjacent driven shafts 440 mesh with each other.

[0044] For example, such as Figure 6 As shown, the second gear 432 is sleeved on the driven shaft 440 located in the middle. The driven component 410 drives the first gear 431 to rotate, the first gear 431 drives the second gear 432 to rotate, and the second gear 432 can drive the driven shaft 440 in the middle to rotate. The driven gear 433 on the driven shaft 440 in the middle can drive the driven gears 433 on the driven shafts 440 on both sides to rotate, thereby achieving synchronous rotation.

[0045] In some embodiments of this utility model, the driven component 410 includes a rocker arm 411 and a drive shaft 412. The drive shaft 412 is rotatably mounted on the base frame 100. The rocker arm 411 is connected to the drive shaft 412. The drive shaft 412 is sleeved and connected to the first gear 431. The rocker arm 411 extends the lever arm for the user to apply force, thereby saving the user's effort and making the operation simpler.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
