TECHNICAL FIELD

[0001] The present application relates to the technical field of assembly equipment, in particular to an automatic grouping and shielding assembly mechanism for long pins of an electrical connector. BACKGROUND

[0002] Currently, the assembly of GF5M long pins is a very difficult process in the product assembly process. This process requires the assembly of 72 long pins with two pieces of shielding mesh. The long pins are dense and slender, and there is no double-end positioning, making assembly difficult. Specifically, the 72 long pins need to be assembled into a 4-row 18-column array and assembled with the shielding mesh. The size of the long pins is 80mm x 2.2mm x 2.7mm, the needle spacing is extremely small (0.6mm), the shielding mesh thickness is 0.15mm, and there is no positioning after one end is assembled, making the other end difficult to assemble.

[0003] 1. In the prior art, the long pins are usually assembled one by one by hand. This method has the following problems:

[0004] 1) The long pins are dense and slender, making manual operation difficult and prone to bending or damaging the pins.

[0005] 2) The needle spacing is extremely small, making manual assembly inefficient and prone to errors.

[0006] 3) The shielding mesh is thin, and is prone to deformation during manual assembly, making assembly difficult.

[0007] 4) After assembling the single-sided shielding mesh, the other end needs to be assembled with 72 pins, which takes a long time and is inefficient.

[0008] 5) Manual assembly is labor-intensive, and product quality consistency is difficult to guarantee.

[0009] Manual assembly not only consumes time and effort, but also makes it difficult to ensure assembly accuracy and consistency. Therefore, there is an urgent need for an automated assembly device to solve these problems.

[0010] 2. The prior art has the following disadvantages in the assembly process of the long pin array and the shielding mesh:

[0011] 1) Difficulty in assembling the pins one by one by hand: The long pins are dense and slender, making manual operation difficult and prone to bending or damaging the pins.

[0012] 2) No double-end positioning: The long pins have no double-end positioning, making it difficult to maintain stability during assembly and prone to deviation.

[0013] 3) Extremely small needle spacing: The needle spacing is only 0.6mm, making manual assembly inefficient and prone to errors, and making it difficult to ensure assembly accuracy.

[0014] 4) Shielding net thickness is thin: the shielding net thickness is only 0.15mm, which is easy to deform during manual assembly, leading to assembly difficulty.

[0015] 5) Long assembly time: manual assembly of each product requires 720 seconds, the overall assembly time is long, and the efficiency is low.

[0016] 6) Limited production: due to low efficiency of manual assembly, monthly production is only 870 pieces, which is difficult to meet the demand of mass production.

[0017] 7) High labor intensity: manual assembly has high labor intensity, workers are easy to fatigue, which affects the assembly quality and consistency.

[0018] 8) It is difficult to ensure the consistency of product quality: during manual assembly process, due to human factors, it is difficult to ensure the consistency of product quality, and quality problems are easy to occur.

[0019] Through manual assembly, not only time and effort are consumed, but also the precision and consistency of assembly cannot be guaranteed. Therefore, an automatic assembly device is urgently needed to solve these problems. SUMMARY

[0077] As Figure 1 , Figure 2 , Figure 15As shown, an automatic grouping and shielding assembly mechanism for long pin of electrical connector, comprising clamping mechanism 1, long pin carrier mechanism 2, long pin assembly device 3, long pin clamp mechanism 5 controlled by long pin lifting mechanism 4 to realize longitudinal movement, and shielding net overall assembly mechanism 9 arranged in sequence according to process. Long pin clamp mechanism 5 is provided with removable grid through cavity for grouping and installing long pin array 10. One long pin 10-11 is arranged in each grid of grid through cavity. The array structure of grid through cavity is same as the arrangement structure of long pin array. Each layer of grid through cavity is aligned with a long pin grouping 10-1. Longitudinally arranged long pin groupings 10-1 form long pin array 10. Clamping mechanism 1 places longitudinally arranged long pin groupings 10-1 on long pin carrier mechanism 2. Longitudinally arranged long pin groupings 10-1 are multiple long pins arranged in the same plane in transverse direction. Long pin clamp mechanism 5 is arranged in front of long pin carrier mechanism 2. Long pin assembly device 3 positions long pin groupings 10-1 on long pin carrier mechanism 2, and pushes long pin groupings 10-1 into grid through cavity of long pin clamp mechanism 5 along longitudinal direction to realize long pin array 10 grouping according to longitudinal height change of long pin clamp mechanism 5. The structure of long pin assembly device 3 does not affect the pushing and entering of long pin groupings 10-1 into long pin clamp mechanism 5 during positioning. Long pin clamp mechanism 5 with completed long pin array 10 grouping is placed in shielding net installation station. Shielding net overall assembly mechanism 9 realizes the assembly of shielding net at both ends of long pin array. After the assembly of shielding net, the product is removed from the clamping and limiting of the grid through cavity in long pin clamp mechanism 5.

[0078] The application also comprises long pin pitch changing mechanism 6 for changing the pitch of long pin groupings 10-1. Long pin pitch changing mechanism 6 changes the pitch of long pin from raw material pitch to assembly pitch of shielding net. Long pin pitch changing mechanism 6 can realize the pitch change of long pin by using common structures such as pushing and pulling, clamping and expanding, etc.

[0079] As shown, Figure 4 Long pin carrier mechanism 2 is composed of multiple long pin carriers 2-1 arranged in transverse direction. One long pin 10-11 is arranged on each long pin carrier 2-1. For example, if the number of long pins to be inserted is 4, the number of long pin carriers 2-1 is 4. The groove for placing long pin 10-11 on long pin carrier 2-1 should be gap matched with long pin 10-11 to prevent long pin 10-11 from shifting when the position of long pin carrier 2-1 changes. Long pin pitch changing mechanism 6 changes the pitch between long pins 10-11 by pushing and pulling long pin carrier 2-1.

[0080] As shown, Figure 3 , Figure 4As shown, the side of the long pin pitch changing mechanism 6 is provided with a pitch changing pressure block 7 for limiting the long pin group 10-1 being pitch changed upwards, and the pitch changing pressure block 7 is moved by the pitch changing pressure cylinder 8 to control the release or implementation of the limiting. The pitch changing pressure block 7 can also play a role of upward limiting when the long pin group 10-1 is pushed by the long pin assembly device. Before assembling a new round of long pin group 10-1, the pitch changing pressure block 7 is released from the limiting.

[0081] As shown in Figure 3 , Figure 4 , Figure 5 The long pin pitch changing mechanism 6 includes a pitch changing cylinder 6-1, a pitch changing guide shaft fixing block 6-2, a pitch changing guide shaft 6-3, a pitch changing limiting block 6-4 and a pitch changing base 6-5. The pitch changing limiting block 6-4 is fixed between the long pin carriers 2-1 for limiting the pitch changing distance. The pitch changing guide shaft fixing block 6-2, the long pin carrier mechanism 2 and the pitch changing base 6-5 are sequentially installed on the pitch changing guide shaft 6-3. The pitch changing base 6-5 is fixedly arranged. The long pin carriers 2-1 on both sides of the long pin carrier mechanism 2 are respectively fixedly connected with the pitch changing base 6-5 and the pitch changing guide shaft fixing block 6-2. The pitch changing guide shaft fixing block 6-2 is driven by the pitch changing cylinder 6-1 to move along the pitch changing guide shaft 6-3, so as to compress or expand the distance between the long pin carriers 2-1. The pitch changing limiting block 6-4 is composed of two fixed columns fixed on adjacent long pin carriers and a pitch changing ring sleeve sleeved on the two fixed columns. By changing the size of the fixed column and the length of the pitch changing ring sleeve, the distance between the two adjacent long pin carriers can be changed. Similarly, the pitch changing limiting block 6-4 can adopt a connecting rod structure to achieve the same function. The pitch changing cylinder 6-1 can be replaced by other linear reciprocating components.

[0085] 2) The long pin distance changing mechanism 6 drives the long pin carrier 2-1 to change the distance;
