Description

Technical Field

[0001] This utility model relates to the technical field of bamboo and wood furniture processing equipment, specifically to an automatic assembly machine for a square frame made of bamboo or wood. Background Technology

[0002] In the production process of bamboo or wooden square frames, the processing and assembly of partitions and partition strips are crucial steps to ensure frame quality and production efficiency. However, existing processing equipment has significant technical shortcomings in terms of automation and processing precision, specifically as follows:

[0003] In the processing of partition panels, traditional equipment generally adopts a single-process manual or semi-automatic operation mode, requiring drilling, gluing, and installing wooden dowels to be completed step by step. Drilling relies on a single drill bit to work sequentially, resulting in large errors in hole spacing and low efficiency; gluing relies on manual application or single-tube injection, leading to uneven glue application and easy leakage; installing wooden dowels requires manual alignment and insertion into the holes, resulting in inconsistent dowel protrusion lengths, which affects the subsequent splicing accuracy with the partition strips. As the core connector of the frame, the accuracy of hole positions, glue application control, and the quality of wooden dowel assembly directly determine the overall stability of the frame. Defects in any of these aspects can lead to loosening or deformation of the frame splicing.

[0004] Regarding frame assembly, existing equipment primarily relies on manual positioning and splicing, making automated synchronous operation impossible. The gluing of the partition strip holes also depends on manual operation, resulting in poor precision and inconsistent glue volume control. During splicing, manual alignment of the partition stops and partition strip holes is required, and relative positional deviations between the stops and strips are difficult to avoid. Furthermore, uneven pressure during fixing leads to some wooden dowels not being fully inserted into the holes, increasing the risk of frame collapse. In reality, these semi-finished frames caused by splicing deviations could be reused if reinforced with secondary pressure, but due to the lack of automated correction and reinforcement mechanisms in existing equipment, they can only be reworked manually or scrapped directly, increasing production costs and material waste.

[0005] Therefore, how to provide a method that can automate the processing of partitions and reduce the impact of manual operation on accuracy and efficiency during the frame assembly stage through precise positioning, automatic glue dispensing, and stable splicing mechanisms, in order to solve the problems of insufficient processing accuracy, poor assembly stability, and low production efficiency in the existing technology, is a problem that urgently needs to be solved by those skilled in the art.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] like Figures 1-9 The diagram shows the preferred embodiment of this utility model. The automatic frame assembly machine in this embodiment mainly includes core components such as a frame assembly 1, a partition plate processing unit 2, and a frame assembly unit 3. These components are precisely laid out and connected by transmission to achieve fully automated processing and assembly of the bamboo and wood square frame. Multiple partition strips and two partition plates are perpendicular to each other. During installation, the two partition plates are pressed together at both ends of the partition strips to form a complete frame. The specific structure, connection method, and working principle of each component are described in detail below.

[0047] The structure and connection relationship of each core component are as follows:

[0048] Rack assembly 1: Reference Figure 1 As shown, the frame assembly 1 serves as the basic support for the equipment, integrating a partition plate processing area 1a and an assembly work area 1b. The partition plate processing area 1a is used to install the partition plate processing unit 2, and the assembly work area 1b is used to install the frame assembly unit 3. A support platform 1c is also provided on the top of the frame assembly 1 for temporary support during frame reinforcement. Each functional unit is fixed to the frame assembly 1 by bolts or guide rails to ensure overall stability. The frame assembly 1 can also be divided into two independent parts, used to house the partition plate processing area 1a and the assembly work area 1b, respectively.

[0049] Partition plate processing unit 2: Reference Figure 2 As shown, the partition processing unit 2 is arranged along the production line direction in the partition processing area 1a to realize the continuous processing of partitions. Each complete frame requires two partitions. The partition processing unit 2 includes a feeding station 4, a drilling station 5, a glue dispensing station 6, a wooden dowel assembly station 7, and a station transfer component 8, etc.

[0050] Material loading station 4: Reference Figure 2As shown, the loading station 4 is equipped with a partitioned loading bin 4a. The internal contour of the loading bin 4a is adapted to the partitioned baffle and is used to stack and store unprocessed partitioned baffles. There are notches 4a1 on both sides of its bottom. The height of the notch is slightly greater than the thickness of the partitioned baffle, so that the partitioned baffle can be moved out laterally.

[0051] Drilling station 5: Reference Figure 2 As shown, the feeding station 4 is equipped with multiple drill bits 5a. The number of drill bits 5a matches the mounting hole requirements on the partition. The holes are arranged at intervals along the length of the partition and fixed side by side on the drilling base 5b. The drilling base 5b is slidably connected to the frame assembly 1 through the first guide rail structure 5c. The first guide rail structure 5c can be a combination of a slider and a guide rail. The sliding direction is perpendicular to the conveying direction of the production line. The feeding action is driven by the first drive component 5d, which can be a cylinder or a servo motor. The drill bits 5a are connected to the first motor 5e through the transmission component 5f to ensure that all drill bits rotate synchronously. The transmission component 5f can be a gear or belt drive. A first clamping mechanism 5g is also provided to clamp the partition from above during drilling to prevent vibration from causing the hole position to shift. The first clamping mechanism 5g can be achieved by a cylinder driving the pressure block from top to bottom.

[0052] Dispensing Station 6: Reference Figure 2 As shown, the dispensing mechanism 6a is fixed on the dispensing base 6b and has a dispensing port 6a1 that corresponds one-to-one with the mounting hole. The dispensing base 6b is slidably connected to the frame assembly 1 through the second guide rail structure 6c. Its sliding direction is perpendicular to the production line. The position is adjusted by the second drive component 6d to ensure that the dispensing port 6a1 is accurately aligned with the mounting hole. The structure of the second pressing mechanism 6e is similar to that of the first pressing mechanism. It is used to fix the partition during dispensing to prevent uneven glue application.

[0053] Wood dowel assembly station 7: Reference Figure 2As shown, the dowel assembly station 7 integrates a dowel feeding mechanism 7a, a dowel positioning component 7b, a pressing actuator 7c, a dowel assembly seat 7d, a guide drive component 7e, and a third pressing mechanism 7f. The dowel feeding mechanism 7a includes a vibratory feeder 7a1 and a conveying pipe 7a2. One end of the conveying pipe 7a2 is connected to the outlet of the vibratory feeder 7a1, and the other end extends to the side assembly position of the partition, used to orderly convey the dowels to the assembly position. The dowel positioning component 7b has multiple dowel grooves 7b1 arranged side by side at intervals. The spacing of the dowel grooves 7b1 is consistent with the spacing of the mounting holes on the partition, and they are located on the side of the partition and laterally correspond to the mounting holes, used to receive the dowels conveyed by the conveying pipe 7a2. The pressing actuator 7c includes components corresponding to the dowel grooves 7b1. The corresponding push rod 7c1 and the third drive component 7c2 that drives the push rod 7c1 to move laterally are used to press the wooden dowel laterally into the mounting hole from the side of the partition. The wooden dowel assembly seat 7d, the discharge end of the wooden dowel feeding mechanism 7a, the wooden dowel positioning component 7b and the pressing execution mechanism 7c are all fixedly installed on it. The guide drive component 7e includes a third guide rail structure 7e1 and a fourth drive component 7e2. The wooden dowel assembly seat 7d is slidably connected to the frame assembly 1 through the third guide rail structure 7e1, and the sliding direction is perpendicular to the production line conveying direction. The fourth drive component 7e2 drives the wooden dowel assembly seat 7d to move along the third guide rail structure 7e1 to achieve alignment. A third pressing mechanism 7f is also provided to press the partition from top to bottom during the wooden dowel pressing process to prevent it from shifting.

[0054] Workstation Transfer Component 8: Reference Figure 2 As shown, the workstation transfer assembly 8 includes a gripper group 8a, a transfer carriage 8b, and a first drive assembly. The transfer carriage 8b spans from the loading station 4 to the wood dowel assembly station 7 and is connected to the frame assembly 1 via a bidirectional guide rail structure, allowing it to slide back and forth and left and right relative to the frame assembly 1 as needed. The gripper group 8a has three pairs, with the gripper parts of the gripper group 8a adapted to both ends of the partitions and fixed to the transfer carriage 8b, with their positions corresponding to the three adjacent workstations. The first drive assembly drives the transfer carriage 8b to move, enabling the gripper group 8a to simultaneously grip and transfer the two partitions belonging to the two workstations.

[0055] Here is an additional explanation: The first drive component in this embodiment adopts existing technology and is not shown in the attached drawings. It is a dual-axis drive unit, which is equipped with a servo motor and a ball screw transmission pair along the production line direction to realize the precise translation of the transfer carriage 8b; a high-precision cylinder is configured perpendicular to the production line direction to control the lateral picking and placing action of the gripper group 8a. The dual-axis drive, together with the linear guide rail slider group at the bottom of the transfer carriage 8b, ensures that the three pairs of gripper groups 8a move synchronously.

[0056] Another point is that after the partition block processing unit 2 completes the drilling, gluing, and wooden dowel assembly, the partition block is transferred to the discharge end of the partition block processing unit 2 through the station transfer component 8. At this time, the processed partition block can be manually placed layer by layer into the partition block placement bin 13 of the frame assembly unit 3, and it must be ensured that the exposed end of the wooden dowel of the partition block is facing down, so as to facilitate the assembly with the subsequent partition strips.

[0057] Frame assembly unit 3: Reference Figure 3 As shown, the frame assembly unit 3 is located in the assembly work area 1b and is used to realize the vertical assembly of multiple partition strips and two partition blocks. It includes a feeding table 9, a partition strip placement chamber 10, a first transfer mechanism 11, a transverse pushing component 11a, a longitudinal pushing component 11b, a partition strip dispensing module 12, a partition block placement chamber 13, a second transfer mechanism 14, a pressing mechanism 15, and a discharge conveyor belt 16, etc.

[0058] Feeding table 9: reference Figure 3 , Figure 4 and Figure 7 As shown, the upper surface of the feeding table 9 is provided with multiple positioning grooves 9a. The positioning grooves 9a are arranged at intervals along the moving direction of the feeding table, and the spacing is adapted to the spacing of the pre-machined mounting holes of the partition bars. Each positioning groove 9a is mainly used to receive and position multiple partition bars, which are placed at intervals along the length of the feeding table. The feeding table 9 moves horizontally through the feeding table drive mechanism 9b. The feeding table drive mechanism 9b includes a second motor 9b1 and a lead screw 9b2 connected to the output shaft of the second motor 9b1. The lead screw 9b2 cooperates with the threaded hole 9c at the bottom of the feeding table 9. When the second motor 9b1 rotates, it drives the feeding table 9 to slide horizontally along the preset guide rail.

[0059] Partition bar placement compartment 10: Reference Figure 3 and Figure 4 As shown, there are two partition strip placement chambers 10, which are respectively located on both sides of the feeding table 9 and staggered along the moving direction of the feeding table 9. The staggered distance between the two is equal to the distance between two adjacent positioning slots 9a. Both partition strip placement chambers 10 are used to stack and store multiple partition strips with pre-drilled holes. The length direction of the partition strips is perpendicular to the moving direction of the feeding table 9.

[0060] First Transfer Agency 11: Reference Figure 4As shown, each partition bar placement chamber 10 is equipped with a first transfer mechanism 11, which includes a transverse pushing component 11a and a longitudinal pushing component 11b. The transverse pushing component 11a includes a first cylinder 11a1, with a push plate connected to the end of the piston rod, for pushing the partition bar laterally out of the placement chamber; the longitudinal pushing component 11b includes a second cylinder 11b1, which is arranged perpendicularly to the first cylinder 11a1, for receiving the laterally moved partition bar and pushing it into the positioning slot 9a, ensuring that multiple partition bars are arranged parallel along the length of the feeding table. Through the staggered arrangement of the partition bar placement chambers 10, the partition bars in two partition bar placement chambers 10 can be pushed simultaneously into two adjacent positioning slots 9a.

[0061] Partition strip dispensing module 12: Reference Figure 4 As shown, the partition strip dispensing module 12 is fixed on the bracket above the feeding table 9, and the bracket is fixedly connected to the frame assembly. The dispensing port of the partition strip dispensing module 12 is aligned with the reserved holes at both ends of the partition strip in the positioning groove 9a. There can be two or more dispensing ports here, which are used to inject adhesive into multiple reserved holes on the same side at one time. The reserved holes here are mainly used to connect with the wooden dowels of the partition.

[0062] Partition barrier for storage compartment 13: Reference Figure 5 and Figure 6 As shown, there are two partition block placement compartments 13, which are respectively located on both sides of the feeding table 9. They are used to store two partition blocks that have been loaded with wooden pegs. The length direction of the partition block is consistent with the moving direction of the feeding table, while it is perpendicular to the partition strip.

[0063] Second transfer agency 14: Reference Figure 6 As shown, the second transfer mechanism 14 includes a horizontal pushing assembly 14a and a clamping and transferring assembly 14b. The horizontal pushing assembly 14a includes a third cylinder 14a1, used to push the bottommost partition block in the partition block placement compartment 13 to a preset position; the clamping and transferring assembly 14b includes two sets of fourth cylinders 14b1, which can be finger cylinders, arranged opposite each other on both sides of the feeding table, used to clamp the two ends of two partition blocks respectively, and transfer the corresponding partition blocks to the top of the two ends of multiple partition strips, ensuring that the wooden dowels are vertically aligned with the reserved holes of the partition strips.

[0064] Pressing mechanism 15: Reference Figure 3 As shown, the pressing mechanism 15 includes a pressing drive assembly 15a and a pair of pressure plates 15b. The pressing drive assembly 15a is fixed to the crossbeam of the frame assembly 1, and its output end is connected to the pressure plates 15b. The pressure plates 15b are respectively positioned opposite two partition stops and are used to drive the partition stops to move downwards, pressing them against the two ends of multiple partition strips, so that the wooden dowels are embedded in the reserved holes to form a vertically intersecting complete frame. The drive assembly 15a can be a hydraulic cylinder or a servo electric cylinder.

[0065] Discharge conveyor belt 16: Reference Figure 8 As shown, the conveying path of the discharge conveyor belt 16 and the moving path of the feeding table 9 partially overlap in the vertical projection direction. A pair of conveyor belt lifting mechanisms 16a are provided on the drive shaft of the discharge conveyor belt 16. The discharge conveyor belt 16 is connected to the frame assembly 1 through the conveyor belt lifting mechanism 16a, which can realize vertical lifting and lowering, and is used to receive and transport the assembled frame.

[0066] Frame reinforcement mechanism 17: Reference Figure 8 As shown, the frame reinforcement mechanism 17 is located above the discharge conveyor belt 16 and includes a fixed bracket 17a and a reinforcement plate 17c. The fixed bracket 17a is fixed to the frame assembly and has four vertical guide columns 17b. The reinforcement plate 17c has guide holes 17c1 that cooperate with the guide columns 17b. The driving end of the reinforcement drive component 17d drives and connects to the reinforcement plate 17c, which is used to perform secondary pressure stabilization at the vertical joints of the frame. The reinforcement drive component 17d can be a pneumatic cylinder or an electric cylinder, which is used to perform secondary pressure stabilization at the vertical joints of the frame.

[0067] The working principle of the automatic frame assembly machine in this embodiment is as follows:

[0068] 1. Partition plate processing

[0069] Feeding: The gripper assembly 8a of the station transfer component 8 grabs the bottom partition from the gap 4a1 of the partition feeding bin 4a and transfers it to the drilling station 5.

[0070] Drilling: The first clamping mechanism 5g presses down to fix the partition plate, the first motor 5e drives multiple drill bits 5a to rotate synchronously, and the first driving component 5d drives the drill seat 5b to feed along the first guide rail structure 5c, completing the processing of multiple mounting holes in one go;

[0071] Transfer and dispensing: The transfer carriage 8b drives the gripper assembly 8a to move the perforated partition to the dispensing station 6. After the second clamping mechanism 6e is fixed, the second drive component 6d adjusts the position of the dispensing seat 6b, and the dispensing port 6a1 injects a quantitative amount of adhesive into the mounting hole.

[0072] Wood dowel assembly: The transfer carriage 8b moves the glued partition to the wood dowel assembly station 7, and the third pressing mechanism 7f presses down to fix the partition; the vibratory plate 7a1 transports the wood dowels in an orderly manner through the conveying pipe 7a2 to the wood dowel groove 7b1 on the side of the partition, and the wood dowel groove 7b1 corresponds laterally to the mounting hole; the fourth driving component 7e2 drives the wood dowel assembly seat 7d to move along the third guide rail structure 7e1 to achieve precise alignment; the third driving component 7c2 drives the push rod 7c1 to move laterally, pressing the wood dowels laterally into the mounting hole from the side of the partition to ensure that the exposed length of the wood dowels is consistent.

[0073] 2. Frame assembly

[0074] Partition bar feeding: The first cylinder 11a1 of the first transfer mechanism 11 pushes the partition bar out laterally from the placement chamber, and the second cylinder 11b1 pushes it longitudinally into the positioning groove 9a of the feeding table 9. Multiple partition bars are arranged in parallel along the length of the feeding table.

[0075] Partition strip dispensing: The feeding platform drive mechanism 9b drives the feeding platform 9 to move below the partition strip dispensing module 12, and after completing the dispensing of the pre-drilled holes at both ends, it continues to move to the assembly position;

[0076] Partition plate transfer and alignment: The third cylinder 14a1 of the second transfer mechanism 14 pushes the two partition plates out of the placement chamber, and the fourth cylinder 14b1 clamps the two ends of the two partition plates respectively and transfers them to the top of the two ends of the multiple partition strips. Here the partition plates and partition strips are perpendicular to each other and ensures that the wooden dowels are accurately aligned with the reserved holes.

[0077] Pressing: Pressing drive assembly 15a drives pressure plate 15b to move downward, pressing the two partition plates onto both ends of the multiple partition strips respectively, so that the exposed parts of the wooden dowels are fully embedded in the reserved holes, forming a complete vertically intersecting frame T. See details. Figure 9 As shown, T1 is a partition barrier and T2 is a partition strip.

[0078] 3. Discharge and reinforcement

[0079] Discharge: The conveyor belt lifting mechanism 16a drives the discharge conveyor belt 16 to rise, lifting the assembled frame out of the positioning groove 9a and transporting it to the reinforcement station;

[0080] Secondary pressure stabilization: When the compressed frame is transported to the reinforcement station, the conveyor belt lifting mechanism 16a drives the discharge conveyor belt 16 to descend, so that the frame is separated from the conveyor belt and placed on the support platform 1c of the frame assembly 1. The reinforcement drive component 17d drives the reinforcement plate 17c to press down, and performs secondary pressure stabilization on the frame joint. After the pressure stabilization is completed, the reinforcement plate 17c returns to its original position, the discharge conveyor belt 16 rises to reset and continues to transport the frame to the next stage.

[0081] This embodiment solves the problems of deviation in the vertical relationship between partition strips and partition barriers and weak splicing in traditional manual assembly by using "continuous operation of partition processing unit + vertical alignment and pressing of frame assembly unit". It realizes fully automated production of bamboo and wood frames from raw materials to finished products, significantly improving production efficiency and product consistency.
