[0025] An object of the present invention is to further provide a material distributing mechanism that does not directly impact the low-voltage electrical appliance when stopping it, protecting the low-voltage electrical appliance from damage.

[0026] To achieve this object, the present invention adopts the following technical solutions:

[0027] A material distribution mechanism includes a conveyor line, a stop baffle, and a stop unit. The stop baffle is fixedly arranged on one side of the conveyor line, and the stop unit is arranged on the other side of the conveyor line. The stop unit includes a first stop assembly and a second stop assembly. Both the first stop assembly and the second stop assembly include a stop driving member and a stop block. The stop driving member of the first stop assembly is used to drive the stop block, and the stop block makes the first low-voltage electrical appliance on the conveyor line along the conveying direction of the conveyor line abut against the stop baffle. The stop driving member of the second stop assembly is used to drive the stop block, and the stop block makes the second low-voltage electrical appliance adjacent to the first low-voltage electrical appliance on the conveyor line abut against the stop baffle. The surface of the stop block in contact with the low-voltage electrical appliance is an inclined surface, and the distance between the inclined surface and the stop baffle decreases along the conveying direction of the conveyor line.

[0028] Advantages of the present invention:

[0029] For the pin assembly device provided by the present invention, the conveyor line is used to convey low-voltage electrical appliances to the position of the feeding mechanism. The feeding mechanism pushes the low-voltage electrical appliances on the conveyor line to the pin assembly position. The pin assembly mechanism assembles pins to the low-voltage electrical appliances placed at the pin assembly position. The material transfer mechanism pushes the low-voltage electrical appliances with pins assembled to the pin detection position for detection. After the detection is completed, the pushing mechanism pushes the detected low-voltage electrical appliances to the conveyor line. The feeding mechanism, the pin assembly mechanism, the material transfer mechanism, and the pushing mechanism cooperate with each other during operation, and multiple mechanisms will act simultaneously at the same time, realizing the high-efficiency assembly of pins. In addition, the automatic pin assembly replaces manual operation, reduces labor costs, avoids the occurrence of missing assembly problems, and improves the qualified rate of products.

[0030] For the material distribution mechanism provided by the present invention, the surface of the stop block in contact with the low-voltage electrical appliance is an inclined surface, and the distance between the inclined surface and the stop baffle decreases along the conveying direction of the conveyor line. The stop driving member of the first stop assembly is used to drive the stop block, and the stop block makes the first low-voltage electrical appliance on the conveyor line abut against the stop baffle, so that the first low-voltage electrical appliance cannot move along the conveying direction of the conveyor line. The stop driving member of the second stop assembly is used to drive the stop block, and the stop block makes the second low-voltage electrical appliance on the conveyor line abut against the stop baffle. When the second stop assembly presses the second low-voltage electrical appliance and the first stop assembly no longer presses the first low-voltage electrical appliance, the first low-voltage electrical appliance can move along the conveying direction of the conveyor line, thereby realizing the automatic feeding of low-voltage electrical appliances. The inclined surface of the stop block cooperates with the stop baffle to realize the blocking of the low-voltage electrical appliance, rather than directly applying pressure to the low-voltage electrical appliance. This material distribution mechanism will not cause impact on the low-voltage electrical appliance and protects the low-voltage electrical appliance from damage. Description of the drawings

It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only parts related to the present invention are shown in the drawings, rather than all structures.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0055] like Figures 1 to 3 As shown, this embodiment provides a pin assembly device, which includes a conveyor line 1, a loading mechanism 2 is provided on one side of the conveyor line 1, a pin assembly platform 3 is provided on the other side of the conveyor line 1, the pin assembly platform 3 has a pin assembly position and a pin detection position, a pin assembly mechanism 4 is provided above the pin assembly position, and a material moving mechanism 5 and a material pushing mechanism 6 are provided on the side of the pin assembly platform 3 away from the conveyor line 1. The material shifting mechanism 5 is used to move between the pin assembly position and the pin detection position, and when moving to the pin detection position, the low-voltage electrical appliance 100 with the pin assembled at the pin assembly position is pushed to the pin detection position; while the low-voltage electrical appliance 100 is being detected at the pin detection position, the material shifting mechanism 5 moves from the pin detection position to the pin assembly position, and the loading mechanism 2 is used to push the low-voltage electrical appliance 100 on the conveyor line 1 to the pin assembly position, and the material pushing mechanism 6 is used to push the low-voltage electrical appliance 100 with the pin detection position detected to the conveyor line 1; the pin assembly mechanism 4 is used to assemble pins into the low-voltage electrical appliance 100 placed at the pin assembly position, and the material pushing mechanism 6 moves to the initial position.

[0056] The conveyor line 1 is used to convey the low-voltage electrical appliance 100 to the position of the feeding mechanism 2. The feeding mechanism 2 pushes the low-voltage electrical appliance 100 on the conveyor line 1 to the pin assembly position. The pin assembly mechanism 4 assembles pins on the low-voltage electrical appliance 100 placed at the pin assembly position. The material moving mechanism 5 pushes the low-voltage electrical appliance 100 with assembled pins to the pin detection position for detection. After the detection is completed, the low-voltage electrical appliance 100 that has been detected is pushed to the conveyor line 1 by the pushing mechanism 6. The feeding mechanism 2, the pin assembly mechanism 4, the material moving mechanism 5 and the pushing mechanism 6 cooperate with each other during operation. At the same time, multiple mechanisms will act simultaneously, realizing high-efficiency assembly of pins. In addition, automatic assembly of pins replaces manual operations, reduces labor costs, avoids the occurrence of missing installation problems, and improves the qualified rate of products.

[0057] In some embodiments, Figure 4 and Figure 5As shown, the pin assembly platform 3 includes a first mounting plate 31 and a second mounting plate 32, the first mounting plate 31 and the second mounting plate 32 are parallel and spaced apart, and a pin assembly position and a pin detection position are formed between the first mounting plate 31 and the second mounting plate 32. The feeding mechanism 2 pushes the low-voltage electrical appliance 100 on the conveyor line 1 into the space between the first mounting plate 31 and the second mounting plate 32. The pin assembly position and the pin detection position are spaced apart along the second direction, so that in the second direction, both ends of the first mounting plate 31 are connected to the second mounting plate 32 through the first blocking block 35, the height of the first blocking block 35 is the same as the spacing between the first mounting plate 31 and the second mounting plate 32, and the two first blocking blocks 35 also play the role of limiting the low-voltage electrical appliance 100 in the second direction, so as to prevent the low-voltage electrical appliance 100 from detaching from the first mounting plate 31 when the material shifting mechanism 5 pushes the low-voltage electrical appliance 100 that has completed the pin assembly at the pin assembly position to the pin detection position.

[0058] A second stopper 36 and a third stopper 37 are provided on the side of the second mounting plate 32 facing the first mounting plate 31. The second stopper 36 extends in the second direction. One end of the second stopper 36 extends to the first stopper 35 near the pin detection position. One end of the third stopper 37 is connected to the other end of the second stopper 36. The other end of the third stopper 37 extends in the second direction. The third stopper 37 is placed on the side of the pin assembly position away from the pin detection position. When the feeding mechanism 2 pushes the low-voltage electrical appliance 100 on the conveyor line 1 to the pin assembly position, the third stopper 37 and the second stopper 36 play a role in limiting the low-voltage electrical appliance 100 in the first direction and the second direction, so as to ensure that the material shifting mechanism 5 can accurately push the low-voltage electrical appliance 100 to the pin detection position. In order not to hinder the movement of the material moving mechanism 5 and the material pushing mechanism 6, the second blocking block 36 and the third blocking block 37 are spaced apart from the first mounting plate 31 for the material moving mechanism 5 and the material pushing mechanism 6 to pass through. At the same time, the height of the second blocking block 36 and the third blocking block 37 can also serve to resist the low-voltage electrical appliance 100.

[0059] In some embodiments, Figure 6 and Figure 7As shown, the assembly device of the pin further includes a positioning mechanism 7. The positioning mechanism 7 includes a positioning block 71 and a positioning driving member 72. When the feeding mechanism 6 moves to the initial position, the positioning driving member 72 is used to drive the positioning block 71 to move, so that the positioning block 71 is placed on one side of the pin detection position. When the transfer mechanism 5 pushes the low-voltage electrical appliance 100 at the pin assembly position to the pin detection position, in the direction of being pushed, the concave portion on the top surface of the low-voltage electrical appliance 100 abuts against the positioning block 71, that is, the positioning block 71 is placed between the low-voltage electrical appliance 100 and the conveyor line 1. While the low-voltage electrical appliance 100 is being detected at the pin detection position, the positioning driving member 72 drives the positioning block 71 to move away from the pin detection position, so that the feeding mechanism 6 can push the low-voltage electrical appliance 100 to the conveyor line 1. The positioning block 71 can limit the low-voltage electrical appliance 100 in the first direction and the second direction. At the same time, the first blocking block 35, the second blocking block 36 cooperate with the positioning block 71, and the bottom of the low-voltage electrical appliance 100 contacts the second blocking block 36 to accurately position the low-voltage electrical appliance 100 at the pin detection position, ensuring the accuracy of the detection of the low-voltage electrical appliance 100.

[0060] Optionally, the positioning driving member 72 is arranged below the pin assembly platform 3. Specifically, the positioning driving member 72 is arranged below the first mounting plate 31, without interfering with the installation of other components. The first mounting plate 31 is provided with a positioning hole. The positioning driving member 72 drives the positioning block 71 to rise and pass through the positioning hole. The positioning block 71 is arranged higher than the first mounting plate 31, and the positioning block 71 can be placed in the concave portion on the top surface of the low-voltage electrical appliance 100 to realize the positioning of the low-voltage electrical appliance 100 in the first direction and the second direction. The positioning driving member 72 drives the positioning block 71 to descend so that the positioning block 71 is placed below the first mounting plate 31, or the positioning block 71 is flush with the surface of the first mounting plate 31, so that the feeding mechanism 6 can push the low-voltage electrical appliance 100 to the conveyor line 1.

[0061] See Figure 5 As shown, a pin detection member 9 is arranged at the pin detection position. The pin detection member 9 can be a photoelectric sensor. The pin detection member 9 is used to detect whether a pin is installed on the low-voltage electrical appliance 100. The feeding mechanism 6 pushes the qualified low-voltage electrical appliances 100 to the conveyor line 1. The unqualified low-voltage electrical appliances 100 can be taken out manually, or a rejection device can be set to reject the unqualified low-voltage electrical appliances 100.

[0062] In some embodiments, continue to refer to Figure 6 and Figure 7As shown, the feeding mechanism 2 includes a feeding drive member 21 and a feeding drive block 22. The feeding drive member 21 is fixed to one side of the conveyor line 1, and the feeding drive block 22 is connected to the feeding drive member 21. The feeding drive block 22 is arranged above the conveyor line 1. The feeding drive member 21 drives the feeding drive block 22 to move along the first direction, so that the feeding drive block 22 drives the low-voltage electrical appliance 100 on the conveyor line 1 to move to the pin assembly position of the pin assembly platform 3. The feeding drive member 21 can be a cylinder with a simple structure, which can realize stable driving of the feeding drive block 22 to move along the first direction.

[0063] A material detection component 23 is provided at a position on the conveyor line 1 corresponding to the feeding mechanism 2. The material detection component 23 is used to detect whether there is a low-voltage electrical appliance 100 at this position. When there is a low-voltage electrical appliance 100 at this position, the feeding drive component 21 drives the feeding drive block 22 to push the low-voltage electrical appliance 100 onto the pin assembly platform 3.

[0064] In some embodiments, Figure 8 and Figure 9 As shown, the material moving mechanism 5 includes a first material moving drive unit 51, a second material moving drive unit 52 and a toggle member 53. The first material moving drive unit 51 and the second material moving drive unit 52 are both arranged on the side of the pin assembly platform 3 away from the conveyor line 1, and the toggle member 53 is placed above the pin assembly platform 3. Specifically, the toggle member 53 is placed between the first mounting plate 31 and the second mounting plate 32. The first material moving drive unit 51 is used to drive the second material moving drive unit 52 to move from the pin detection position to the pin assembly position, and the second material moving drive unit 52 is used to drive the toggle member 53 to extend along the first direction, so that the toggle member 53 is located on the side of the pin assembly position away from the pin detection position, or the first material moving drive unit 51 is used to drive the second material moving drive unit 52 to move from the pin assembly position to the pin detection position, so that the toggle member 53 drives the low-voltage electrical appliance 100 at the pin assembly position to move to the pin detection position. When the pin detection position of the low-voltage electrical appliance 100 is detected, the second material moving drive unit 52 placed at the pin detection position drives the toggle member 53 to retract in the first direction, and the first material moving drive unit 51 drives the second material moving drive unit 52 to move from the pin detection position to the pin assembly position, and when the pushing mechanism 6 moves to the initial position, the second material moving drive unit 52 placed at the pin assembly position drives the toggle member 53 to extend in the first direction. Multiple mechanisms act simultaneously at the same time, achieving efficient pin assembly.

[0065] See also Figures 6 to 9As shown, when the pin assembling device is working, the first material transferring driving unit 51 drives the second material transferring driving unit 52 to move from the pin detecting position to the pin assembling position. The second material transferring driving unit 52 drives the toggling member 53 to extend along the first direction. The toggling member 53 is located on the side of the pin assembling position away from the pin detecting position. The first material transferring driving unit 51 drives the second material transferring driving unit 52 to move from the pin assembling position to the pin detecting position, and pushes the low-voltage electrical appliance 100 assembled with pins at the pin assembling position to the pin detecting position. After the low-voltage electrical appliance 100 is pushed to the pin detecting position, the concave portion on the top surface of the low-voltage electrical appliance 100 abuts against the positioning block 71. While the low-voltage electrical appliance 100 is being detected at the pin detecting position, the positioning driving member 72 drives the positioning block 71 to move and away from the pin detecting position. The second material transferring driving unit 52 drives the toggling member 53 to retract along the first direction. The feeding mechanism 2 pushes the low-voltage electrical appliance 100 on the conveying line 1 to the pin assembling position. The feeding mechanism 2 resets. At the same time, the first material transferring driving unit 51 drives the second material transferring driving unit 52 to move from the pin detecting position to the pin assembling position, and the pushing mechanism 6 pushes the low-voltage electrical appliance 100 that has been detected at the pin detecting position to the conveying line 1. Then by Figure 2 The pin assembling mechanism 4 shown assembles pins to the low-voltage electrical appliance 100 placed at the pin assembling position. At the same time, the pushing mechanism 6 moves to the initial position. The second material transferring driving unit 52 drives the toggling member 53 to extend along the first direction. The toggling member 53 is again located on the side of the pin assembling position away from the pin detecting position. And while the pushing mechanism 6 moves to the initial position, the positioning driving member 72 drives the positioning block 71 to move, so that the positioning block 71 is placed on the side of the pin detecting position, and this cycle is carried out accordingly.

[0066] Optionally, the first material transferring driving unit 51 includes a first material transferring driving cylinder 511, the second material transferring driving unit 52 includes a second material transferring driving cylinder. The movable end of the first material transferring driving cylinder 511 is connected with a material transferring slider 512.

[0067] In some embodiments, the pushing mechanism 6 includes a pushing driving member 61 and a pushing block 62. The pushing driving member 61 drives the pushing block 62 to move along the first direction. The pushing driving member 61 can be a cylinder or a linear motor, which is not specifically limited herein.

[0068] In some embodiments, refer to Figure 2 、 Figure 3 and Figure 4As shown, the pin assembly mechanism 4 includes a pin conveying unit 41, a pin installing unit 42, and an intermediate transmission unit 43. The pin conveying unit 41 and the pin installing unit 42 are arranged above the pin assembly platform 3, and the pin installing unit 42 is correspondingly arranged with the pin assembly position. The intermediate transmission unit 43 is used to receive the pins conveyed by the pin conveying unit 41 and convey the pins to the lower part of the pin installing unit 42. The pin installing unit 42 is used to install the pins conveyed by the intermediate transmission unit 43 onto the low-voltage electrical appliance 100 located at the pin assembly position, realizing the automatic installation of pins, replacing manual operation, avoiding the problem of missing installation, and improving the qualified rate of products.

[0069] On the side of the second mounting plate 32 facing away from the first mounting plate 31, a third mounting plate 33 is arranged in parallel and at intervals. Optionally, the third mounting plate 33 is connected to the second mounting plate 32 through positioning columns. Optionally, the intermediate transmission unit 43 includes a turntable 431 and a turntable driving member 432. The turntable 431 is arranged between the second mounting plate 32 and the third mounting plate 33, and the turntable 431 is in contact with the second mounting plate 32. The second mounting plate 32 and the third mounting plate 33 cooperate to limit the position of the turntable 431 in the third direction, preventing the turntable 431 from moving in the third direction. The turntable driving member 432 is arranged on the third mounting plate 33. The turntable 431 is provided with pin bearing holes 433. At the position of the second mounting plate 32 corresponding to the pin installing unit 42, pin installation holes are provided. The turntable driving member 432 is used to drive the turntable 431 to rotate, so that the pin bearing holes 433 receive the pins conveyed by the pin conveying unit 41, or align the pin bearing holes 433 with the pin installation holes. The pins in the pin bearing holes 433 pass through the pin installation holes and fall onto the low-voltage electrical appliance 100 placed at the pin assembly position. The pin installing unit 42 is used to install the pins that have fallen onto the low-voltage electrical appliance 100 through the pin bearing holes 433 and the pin installation holes onto the low-voltage electrical appliance 100. The structure of this intermediate transmission unit 43 is simple and easy to implement. The turntable driving member 432 can be a rotary cylinder or a motor, and no specific limitation is made here.

[0070] The pin conveying unit 41 includes a vibrating bowl 411 and a pin conveying pipe 412. Pins are placed in the vibrating bowl 411. The discharge port of the vibrating bowl 411 is connected to one end of the pin conveying pipe 412. The other end of the pin conveying pipe 412 can be arranged corresponding to the pin bearing hole 433. Specifically, the other end of the pin conveying pipe 412 passes through the third mounting plate 33 and is located above the turntable 431, and the distance between the end of the pin conveying pipe 412 and the surface of the turntable 431 is less than the length of the pin. A conveying pipe fixing sleeve 413 is provided on the third mounting plate 33. One end of the conveying pipe fixing sleeve 413 passes through the third mounting plate 33 and is located above the turntable 431. The other end of the pin conveying pipe 412 is inserted into the conveying pipe fixing sleeve 413. The conveying pipe fixing sleeve 413 serves the purpose of fixing the pin conveying pipe 412, ensuring that the pins can accurately fall into the pin bearing hole 433.

[0071] The vibration of the vibrating bowl 411 causes the pins to be arranged in sequence in the pin conveying pipe 412. The pin at the end of the other end of the pin conveying pipe 412 falls into the pin bearing hole 433. During the rotation of the turntable 431, the pins falling into the pin bearing hole 433 can be cut out. During the process that the turntable 431 rotates and the pin bearing hole 433 moves towards the pin installation hole, the turntable 431 blocks the end of the other end of the pin conveying pipe 412, and the second mounting plate 32 blocks one end of the pin bearing hole 433 facing the second mounting plate 32 until the pin bearing hole 433 is aligned with the pin installation hole, and the pin in the pin bearing hole 433 can pass through the pin installation hole and fall onto the low-voltage electrical appliance 100 placed at the pin assembly position. The structure of the turntable 431 is set to realize the conveying of pins, which does not occupy space and improves the compactness of the structure of the pin assembly mechanism 4.

[0072] Further optionally, as shown in Figure 10 At least two pin bearing holes 433 are provided on the turntable 431, and at least two pin bearing holes 433 are symmetrically arranged relative to the axis of the turntable 431. When one of the two symmetrically arranged pin bearing holes 433 bears the pins conveyed by the pin conveying unit 41, the other pin bearing hole 433 is aligned with the pin installation hole, that is, the pin conveying unit 41 and the pin installation unit 42 can work simultaneously, improving the production efficiency.

[0073] The thickness of the turntable 431 is less than the length of the pin, which is beneficial to the separation of the pins in the pin bearing hole 433 from the pin conveying unit 41.

[0074] A weight-reducing hole 434 is also provided on the turntable 431 to reduce the weight of the turntable 431, thereby reducing the driving load of the turntable driving member 432 and improving the rotation stability of the turntable 431.

[0075] In some other embodiments, the intermediate transfer unit includes a receiving block and a receiving block driving member. The receiving block driving member drives the receiving block to linearly move between the pin conveying unit 41 and the pin mounting unit 42. The receiving block is provided with a pin receiving hole. The movement of the receiving block can place the pin receiving hole below the pin conveying unit 41 to receive the pins, or align the pin receiving hole with the pin mounting hole. The receiving block driving member can be a cylinder or a linear motor, and no specific limitation is made here.

[0076] Continuing to refer to Figure 2 、 Figure 3 and Figure 4 As shown, on the side of the third mounting plate 33 facing away from the second mounting plate 32, a fourth mounting plate 34 is arranged in parallel and at intervals. The turntable driving member 432 is arranged between the third mounting plate 33 and the fourth mounting plate 34. The fourth mounting plate 34 and the third mounting plate 33 can be connected by positioning posts. Optionally, the pin mounting unit 42 includes a pin driving member 421 and an assembly needle 422. The pin driving member 421 is arranged on the side of the fourth mounting plate 34 facing away from the third mounting plate 33. The driving end of the pin driving member 421 penetrates through the fourth mounting plate 34 and is connected to one end of the assembly needle 422. The other end of the assembly needle 422 penetrates through the third mounting plate 33 and is located above the turntable 431. The pin driving member 421 is used to drive the assembly needle 422 to pass through the pin bearing hole 433 and the pin mounting hole. The assembly needle is set according to the characteristics of the pins and the mounting structure of the pins on the low-voltage electrical appliance 100. The pin driving member 421 drives the assembly needle 422 to press the pins into the low-voltage electrical appliance 100.

[0077] Optionally, a guide sleeve 423 is provided on the third mounting plate 33. One end of the guide sleeve 423 penetrates through the third mounting plate 33 and extends towards the turntable 431. The assembly needle 422 is arranged inside the guide sleeve 423. The guide sleeve 423 provides guidance for the movement of the assembly needle 422, ensuring that the assembly needle 422 can accurately pass through the pin bearing hole 433.

[0078] In some embodiments, referring to Figure 3 As shown, the pin assembly device further includes a material distribution mechanism 8. Along the conveying direction of the conveying line 1 (i.e., the second direction), the material distribution mechanism 8 is arranged upstream of the feeding mechanism 2. The material distribution mechanism 8 is used to convey the low-voltage electrical appliances 100 on the conveying line 1 to the feeding mechanism 2 one by one, so as to realize the automatic feeding of the low-voltage electrical appliances 100.

[0079] Optionally, the material distributing mechanism 8 includes a stop baffle 81 and a stop unit 82. The stop baffle 81 is fixedly arranged on one side of the conveyor line 1, and the stop unit 82 is arranged on the other side of the conveyor line 1. The stop unit 82 includes a first stop assembly 821 and a second stop assembly 822. Along the conveying direction of the conveyor line 1, the first stop assembly 821 is used to make the first low-voltage electrical appliance 100 on the conveyor line 1 abut against the stop baffle 81. The first low-voltage electrical appliance 100 is the low-voltage electrical appliance 100 on the conveyor line 1 close to the feeding mechanism 2. The second stop assembly 822 is used to make the second low-voltage electrical appliance 100 on the conveyor line 1 abut against the stop baffle 81. The second low-voltage electrical appliance 100 is the low-voltage electrical appliance 100 adjacent to the first low-voltage electrical appliance 100. When the first low-voltage electrical appliance 100 is conveyed along the conveying direction of the conveyor line 1, the second stop assembly 822 presses against the second low-voltage electrical appliance 100, and the first stop assembly 821 no longer presses against the first low-voltage electrical appliance 100, so that the first low-voltage electrical appliance 100 is separated from the second low-voltage electrical appliance 100. When the first low-voltage electrical appliance 100 does not need to be conveyed, the first stop assembly 821 presses against the first low-voltage electrical appliance 100, and the second stop assembly 822 may not press against the second low-voltage electrical appliance 100.

[0080] Further optionally, both the first stop assembly 821 and the second stop assembly 822 include a stop driving member 8211 and a stop block 8212. The stop driving member 8211 is used to drive the stop block 8212 to abut against the low-voltage electrical appliance 100 on the conveyor line 1, and the surface of the stop block 8212 in contact with the low-voltage electrical appliance 100 is an inclined surface 82121. The distance between the inclined surface 82121 and the stop baffle 81 decreases along the conveying direction of the conveyor line 1. The stop driving member 8211 of the first stop assembly 821 is used to drive the stop block 8212, and the stop block 8212 makes the first low-voltage electrical appliance 100 on the conveyor line 1 along the conveying direction of the conveyor line 1 abut against the stop baffle 81. The stop driving member 8211 of the second stop assembly 822 is used to drive the stop block 8212, and the stop block 8212 makes the second low-voltage electrical appliance 100 adjacent to the first low-voltage electrical appliance 100 on the conveyor line 1 abut against the stop baffle 81. The stop driving member 8211 may be a cylinder, and no specific limitation is made here.

[0081] After the first low-voltage electrical appliance 100 is conveyed along the conveying direction of the conveyor line 1, the first stop assembly 821 acts and is in a state of pressing against the low-voltage electrical appliance 100, and the second stop assembly 822 no longer presses against the second low-voltage electrical appliance 100. The conveyor line 1 conveys the low-voltage electrical appliance 100 to move along the conveying direction. The low-voltage electrical appliance 100 is stopped by the first stop assembly 821, and the inclined surface 82121 is used to stop the low-voltage electrical appliance 100. Compared with the mechanism that directly applies pressure to the low-voltage electrical appliance 100, this structure will not cause impact on the low-voltage electrical appliance 100 and protects the product from damage.

[0082] A product detection member 83 is provided above the position of the first low-voltage electrical appliance 100 near the feeding mechanism 2 on the conveyor line 1. The product detection member 83 is used to detect whether there is a low-voltage electrical appliance 100 on the conveyor line 1. When the product detection member 83 detects that there is a low-voltage electrical appliance 100 at this position and the second stopper assembly 822 is in a state of pressing the second low-voltage electrical appliance 100, the first stopper assembly 821 will no longer press the first low-voltage electrical appliance 100. The product detection member 83 can be an optical fiber probe, and a bracket 84 is connected to the stopper driving member 8211 of the first stopper assembly 821. The bracket 84 extends to the top of the first low-voltage electrical appliance 100, and the product detection member 83 is fixedly mounted on the bracket 84.

[0083] In some other embodiments, the stop unit includes a first stop assembly and a second stop assembly, wherein the first stop assembly includes a baffle plate and a baffle driving member, wherein the baffle driving member is used to drive the baffle plate to extend to stop the first low-voltage electrical appliance 100. The second stop assembly includes a pressing block and a pressing driving member, wherein the pressing driving member drives the pressing block to press the top surface of the second low-voltage electrical appliance 100, so that the bottom surface of the low-voltage electrical appliance 100 contacts the stop plate 81, thereby limiting the position of the second low-voltage electrical appliance 100.

[0084] When assembling a pin using the pin assembly device provided in the present application, the following steps are included:

[0085] First, the conveyor line 1 conveys the low-voltage electrical appliance 100 , and the first stop assembly 821 of the material distribution mechanism 8 stops the first low-voltage electrical appliance 100 close to the feeding mechanism 2 .

[0086] Second, the low-voltage electrical appliance 100 is transported to the upper feeding mechanism 2, the second stop component 822 of the dividing mechanism 8 stops the second low-voltage electrical appliance 100 adjacent to the first low-voltage electrical appliance 100, the first stop component 821 no longer stops the first low-voltage electrical appliance 100, the conveyor line 1 transports the first low-voltage electrical appliance 100 to the dividing mechanism 8, and at the same time the first stop component 821 is in a state of stopping the low-voltage electrical appliance 100, the second stop component 822 no longer stops the second low-voltage electrical appliance 100, so as to continue to transport the low-voltage electrical appliance 100.

[0087] Third, after the low-voltage electrical appliance 100 is transported to the feeding mechanism 2, the pin assembly mechanism 4 assembles pins on the low-voltage electrical appliance 100. The specific assembly method is as described above and will not be repeated here.

[0088] Fourth, the first material moving drive unit 51 drives the second material moving drive unit 52 to move from the pin detection position to the pin assembly position, and the second material moving drive unit 52 drives the shifting member 53 to extend along the first direction. The shifting member 53 is located on the side of the pin assembly position away from the pin detection position.

[0089] Fifth, the first material transfer driving unit 51 drives the second material transfer driving unit 52 to move from the pin assembly position to the pin detection position, pushing the low-voltage electrical appliance 100 assembled with pins at the pin assembly position to the pin detection position. After the low-voltage electrical appliance 100 is pushed to the pin detection position, the concave part on the top surface of the low-voltage electrical appliance 100 abuts against the positioning block 71.

[0090] Sixth, while the low-voltage electrical appliance 100 is being detected at the pin detection position, the positioning driving member 72 drives the positioning block 71 to move away from the pin detection position, and the second material transfer driving unit 52 drives the toggling member 53 to retract along the first direction. The feeding mechanism 2 pushes the low-voltage electrical appliance 100 on the conveyor line 1 to the pin assembly position.

[0091] Seventh, the feeding mechanism 2 resets. While the first material transfer driving unit 51 drives the second material transfer driving unit 52 to move from the pin detection position to the pin assembly position, the feeding mechanism 2 pushes the low-voltage electrical appliance 100 on the conveyor line 1 to the pin assembly position, and the pushing mechanism 6 pushes the low-voltage electrical appliance 100 that has been detected at the pin detection position to the conveyor line 1.

[0092] Eighth, the pin assembly mechanism 4 assembles pins to the low-voltage electrical appliance 100 placed at the pin assembly position. At the same time, the pushing mechanism 6 resets and moves to the initial position. The second material transfer driving unit 52 drives the toggling member 53 to extend along the first direction, and the toggling member 53 is again located on the side of the pin assembly position away from the pin detection position. The feeding mechanism 2 resets, and while the pushing mechanism 6 resets and moves to the initial position, the positioning driving member 72 drives the positioning block 71 to move so that the positioning block 71 is placed on one side of the pin detection position.

[0093] Cycle according to the above steps to realize the installation of pins for the low-voltage electrical appliance 100.
