[0039] See also Figures 1 to 19The present embodiment provides an assembly device, including a workbench 1, on which two assembly plates 2 are distributed along the left and right sides. A circuit board carrier 201 is provided on the opposite sides of the two assembly plates 2. A vertically extending slide 202 is provided in the middle of the circuit board carrier 201. A notch 203 is provided on the side of the slide 202 away from the assembly plate 2. The slide 202 can be used to place a circuit board 11; a circuit board positioning mechanism 3 and a circuit board support mechanism 4 are provided on the opposite sides of the two assembly plates 2. The circuit board positioning mechanism 3 is provided with a positioning column 301, and the circuit board support mechanism 4 is provided with a support block. 401, the circuit board positioning mechanism 3 can drive the positioning column 301 to pass through the assembly plate 2, so that the positioning column 301 can form a positioning effect on the circuit board 11 in the slide 202, and the circuit board support mechanism 4 can drive the support block 401 to pass through the assembly plate 2, so that the support block 401 can form an upward support for the circuit board 11 in the slide 202; a circuit board locking mechanism 5 is provided at the bottom of one of the assembly plates 2, and the circuit board locking mechanism 5 can drive one of the assembly plates 2 to approach the other assembly plate 2, so that the circuit boards 11 in the two slides 202 can be locked together through the slot 203. Function: (1) By including a workbench, the workbench is provided with two assembly plates distributed along the left and right, and the two assembly plates are respectively provided with circuit board carriers on the opposite sides, and the middle part of the circuit board carrier is provided with a vertically extending slide, and the side of the slide away from the assembly plate is provided with a slot, and the slide can be used to place the circuit board; so that the operator can put the two circuit boards into the slides of the two circuit board carriers respectively, and the circuit boards can slide down along the slide. (2) A circuit board positioning mechanism and a circuit board support mechanism are provided on opposite sides of the two assembly plates. The circuit board positioning mechanism is provided with a positioning column, and the circuit board support mechanism is provided with a support block. The circuit board positioning mechanism can drive the positioning column through the assembly plate so that the positioning column can form a positioning effect on the circuit board in the slide groove. The circuit board support mechanism can drive the support block through the assembly plate so that the support block can form an upward support for the circuit board in the slide groove; thereby, the two circuit board support mechanisms can respectively carry the support blocks to support the two circuit boards upward to prevent the circuit boards in the slide groove from continuously sliding downward. Then, the two circuit board positioning mechanisms can respectively carry the positioning columns to position the two circuit boards to improve the position accuracy of the circuit boards. (3) A circuit board fastening mechanism is provided at the bottom of one of the assembly plates. The circuit board fastening mechanism can drive one of the assembly plates close to the other assembly plate so that the circuit boards in the two slide grooves can be fastened together through the notch; thereby, the circuit board fastening mechanism can drive one of the assembly plates close to the other assembly plate so that the two circuit boards will be fastened together through the notch during the process of approaching each other.From the above analysis, it can be seen that compared with the traditional manual fastening method, the present invention has accurate control of the assembly force and position of the corresponding mechanism in the process of fastening two circuit boards together, and the fastening is stable and reliable, which greatly reduces the risk of circuit board failure (while the traditional scheme of manual circuit board fastening has uneven force, inaccurate force, and the circuit board is easily deformed by force; finger pressing can easily cover the chip, causing the chip to be deformed or damaged by force, and the risk of circuit board deformation is high).

[0040] Specifically, a first drive cylinder 302 and a second drive cylinder 402 are respectively provided on the side of the circuit board positioning mechanism 3 and the circuit board support mechanism 4 away from the assembly plate 2. The circuit board positioning mechanism 3 is drivingly connected to the first drive cylinder 302, and the circuit board support mechanism 4 is drivingly connected to the second drive cylinder 402. The first drive cylinder 302 and the second drive cylinder 402 on the outer side of one assembly plate 2 are mounted on the circuit board fastening mechanism 5, while the first drive cylinder 302 and the second drive cylinder 402 on the outer side of the other assembly plate 2 are mounted on the workbench 1. Function: The first drive cylinder 302 and the second drive cylinder 402 can respectively drive the left and right movement of the circuit board positioning mechanism 3 and the circuit board support mechanism 4, while the circuit board fastening mechanism 5 can drive the first drive cylinder 302 and the second drive cylinder 402 mounted thereon to move synchronously.

[0041] Specifically, a third cylinder 501 is provided on the outside of one assembly plate 2. One assembly plate 2 and the third cylinder 501 are driven and connected via a connecting block 502. The connecting block 502 slides left and right with the first linear guide 503 on the circuit board fastening mechanism 5, and the circuit board fastening mechanism 5 slides left and right with the second linear guide 101 on the workbench 1, so that the third cylinder 501 can drive the circuit board fastening mechanism 5 to move left and right. The circuit board positioning mechanism 3 and the circuit board support mechanism 4 on the outside of one assembly plate 2 slide left and right with the first linear guide 503 on the circuit board fastening mechanism 5, and the circuit board positioning mechanism 3 and the circuit board support mechanism 4 on the outside of the other assembly plate 2 slide left and right with the second linear guide 101 on the workbench 1. Function: The third cylinder 501 can drive one assembly plate 2 to move left and right through the connecting block 502, while the other assembly plate 2 remains stationary, while the second linear guide 101 and the first linear guide 503 facilitate the left and right movement of the corresponding circuit board positioning mechanism 3, circuit board support mechanism 4, and circuit board fastening mechanism 5.

[0042] Specifically, the workbench 1 is provided with a working opening 102, which is located below between the two assembly plates 2. A hovering mechanism 6 is provided at the bottom of the slide 202, which is located below the positioning column 301 and the support block 401, so that the hovering mechanism 6 can receive the circuit board 11 that falls from the slide 202. A bottom shell moving mechanism 7 is provided below the workbench 1, which can move the bottom shell 12 to below the working opening 102. A circuit board insertion mechanism 8 is provided above the workbench 1, which can press the two circuit boards 11 on the two hovering mechanisms 6 down through the working opening 102 and insert them into the bottom shell 12 on the bottom shell moving mechanism 7. Function: After the circuit board assembly formed by the two circuit boards are buckled together loses its support, it falls onto the hovering mechanism due to gravity. Then the circuit board insertion mechanism descends to insert the circuit board assembly into the bottom shell.

[0043] Specifically, the suspension mechanism 6 includes two swing arms 601 distributed along the front and rear sides. The tops of the two swing arms 601 are rotatably mounted on the front and rear ends of the bottom of the chute 202, respectively. The bottoms of the two swing arms 601 are rotatably mounted with first deep groove ball bearings 602. A first spring 603 is connected between the bottoms of the two swing arms 601. The two first deep groove ball bearings 602 can receive the circuit board 11 that has fallen from the chute 202. When the circuit board insertion mechanism 8 presses down on the circuit board 11, the circuit board 11 can overcome the elastic tension of the first springs 603, moving the two first deep groove ball bearings 602 away from each other and allowing the circuit board 11 to pass downward. Function: The first spring 603 pulls the two first deep groove ball bearings 602 through the two swing arms 601, overcoming the gravity of the circuit board assembly and supporting the circuit board assembly to prevent it from falling into the bottom shell. Therefore, the force pressing down on the circuit board 11 must overcome the tension of the first springs 603.

[0044] Specifically, the bottom shell moving mechanism 7 includes a third linear guide 701 extending horizontally and a fourth drive cylinder 702. A bottom shell carrier 703 is mounted on the third linear guide 701, and the fourth drive cylinder 702 drives the bottom shell carrier 703 to move horizontally along the third linear guide 701. The bottom shell carrier 703 is provided with an upwardly protruding mounting groove 704, which accommodates the bottom shell 12. Function: The fourth drive cylinder 702 drives the bottom shell carrier 703 to move horizontally along the third linear guide 701, while the upwardly protruding mounting groove 704 facilitates the mating of the bottom shell with the circuit board assembly or the front shell.

[0045] Specifically, the circuit board insertion mechanism 8 includes a fourth linear guide 801 extending left and right, and a fifth drive cylinder 802. A sixth drive cylinder 803 extending vertically is slidably mounted on the fourth linear guide 801. The fifth drive cylinder 802 drives the sixth drive cylinder 803 to move on the fourth linear guide 801 to above the working opening 102. A circuit board pusher 804 is mounted at the bottom of the sixth drive cylinder 803. The sixth drive cylinder 803 drives the circuit board pusher 804 downward, allowing the pusher 804 to push the two circuit boards 11 on the two hovering mechanisms 6 downward through the working opening 102 and into the bottom shell 12 on the bottom shell moving mechanism 7. Function: The fifth drive cylinder 802 drives the sixth drive cylinder 803 to move above the working opening 102. The sixth drive cylinder 803 then drives the circuit board pusher downward, overcoming the supporting force of the hovering mechanism 6 (such as the tension of the first spring 603) and inserting the circuit board assembly into the bottom shell.

[0046] Specifically, a cover shell fastening mechanism 9 is provided on one side of the workbench 1. The cover shell fastening mechanism 9 includes a vertically extending fixed plate 901, on which a fifth linear guide 902 is provided. A sliding plate 903 is slidably provided on the fifth linear guide 902. A cover shell carrier 904 is provided on the sliding plate 903. The sliding plate 903 can move the cover shell carrier 904 downward. A bottom shell moving mechanism 7 extends left and right to below the cover shell carrier 904. The bottom shell moving mechanism 7 can move the bottom shell 12 and the circuit board 11 inside the bottom shell 12 below the cover shell carrier 904, so that the cover shell carrier 904 can fasten the cover shell 13 downward to the bottom shell 12 on the bottom shell moving mechanism 7. Function: Due to the inaccurate control of the force used to fasten the bottom shell and the cover shell of the protective housing, the fastening effect is inconsistent and may even be disengaged in severe cases. Manual assembly relies heavily on human skills, the fastening operation is cumbersome, the reliability is insufficient, and the process quality control is unstable. Therefore, the present invention uses a bottom housing moving mechanism to move the bottom housing assembly, consisting of the bottom housing and circuit board, below the front housing. The front housing fastening mechanism then descends, fastening the front housing into the bottom housing assembly, completing product assembly with a highly effective fastening. The operator removes the fastened product, and the various mechanisms return to their initial states. The equipment then waits for the next operation.

[0047] Specifically, the face shell carrier 904 includes a limiting pressure plate 905 on the upper left and upper right sides and a limiting support plate 906 on the lower left and lower right sides. The limiting pressure plates 905 on the upper left and upper right sides respectively slide left and right with the sixth linear guide rail 907 on the sliding plate 903, and the limiting support plates 906 on the lower left and lower right sides respectively slide left and right with the sixth linear guide rail 907 on the sliding plate 903; the opposite sides of the limiting pressure plates 905 on the upper left and upper right sides are respectively driven and connected with the seventh driving cylinder 908 on the sliding plate 903, and the opposite sides of the limiting support plates 906 on the lower left and lower right sides are respectively connected with the fixed block 909 on the sliding plate 903 through the second spring 910. The limiting pressure plates 905 on the upper left and upper right sides and the limiting support plates 906 on the lower left and lower right sides can clamp the face shell 13 together. Function: The lower left and lower right limit support plates 906 approach each other under the elastic force of the second spring 910, and the lower left and lower right sides of the face shell are placed on the lower left and lower right limit support plates 906 respectively. Then the upper left and upper right limit pressure plates 905 approach each other under the drive of the seventh drive cylinder 908 and move to the upper left and upper right sides of the face shell respectively, thereby limiting the upper and lower directions of the face shell.

[0048] Specifically, the facing sides of the lower left and lower right limiting support plates 906 are respectively provided with downwardly protruding surface shell release control blocks 911, and the bottom ends of the facing sides of the two surface shell release control blocks 911 are respectively provided with inclined surfaces 912; two second deep groove ball bearings 913 distributed along the left and right sides are rotatably arranged on the fixed plate 901, and the two second deep groove ball bearings 913 are respectively located below the two surface shell release control blocks 911, so that the two surface shell release control blocks 911 can be respectively guided downward to cooperate with the two second deep groove ball bearings 913 to drive the lower left and lower right limiting support plates 906 away from each other; a vertically extending eighth drive cylinder 914 is provided on the side of the fixed plate 901 away from the sliding plate 903, and the eighth drive cylinder 914 is drive-connected to the sliding plate 903, and the eighth drive cylinder 914 can drive the sliding plate 903 to move up and down. Function: After the two surface shell release control blocks 911 touch the two second deep groove ball bearings 913, the surface shells are slowly released as the inclined surfaces 912 come into contact, and the surface shells and bottom shell components are completely released after being fastened together.

[0049] Furthermore, circuit boards are sensitive devices and are susceptible to static damage when touched. Preferably, a safety shield 10 is installed on the outside of the assembly equipment. This shield is equipped with an eliminator 1001 and a safety light barrier 1002. The shield provides basic safety features, including dust protection, external isolation, and an observation window. The eliminator eliminates static electricity within a certain range, preventing dust from escaping. The safety light barrier provides feedback to the programmable controller when external interference occurs, which, through program control, shuts off all hazardous inputs and outputs, halting all operations.

[0050] The assembly steps of the product are as follows Figure 16-19 As shown, the product assembly step one: snap the two circuit boards 11 together; the product assembly step two: install the two circuit boards 11 together into the bottom shell 12; the product assembly step three: snap the four elastic buckles 1301 of the surface shell 13 with the four elastic buckle points 1201 of the bottom shell 12 together, and the product assembly is completed.

[0051] In summary, the present invention uses a pneumatic cylinder to position and fasten two circuit boards. The fastened circuit board assembly falls onto a suspension mechanism by gravity, and the bottom shell is moved below the circuit board assembly by the pneumatic cylinder. The pneumatic cylinder pushes the circuit board assembly into the bottom shell. The cylinder then drives the bottom shell and circuit board assembly to below the top shell, where the pneumatic cylinder presses the top shell into engagement with the bottom shell. When the two circuit boards are fastened, a pressure sensor can be provided to monitor and provide feedback on the stress state, ensuring that it is within the allowable stress and deformation range. Various sensors and alarms can also be provided as needed, and these are not listed here.

[0052] Therefore, the present invention can control the movement of the cylinder through a program to automatically assemble the product circuit board and the product protective shell in a specified order. During the assembly process, the fastening status of the product can be monitored and feedback can be provided (such as by setting various laser sensors, etc.). The product assembly is completed by the mutual fastening of the elastic buckles between the product components. The assembly of this equipment is more stable than the traditional manual assembly method, the detection feedback is reliable, it is free and flexible, and it eliminates the risks of electrostatic damage, inadequate fastening, collision, wrong parts, and excessive stress. The equipment automatically fastens, has high production efficiency, low worker fatigue, small size, and saves space.
