Description

Technical Field

[0001] This application relates to the technical field of terminal block assembly, and in particular to an automated device for parallel assembly of terminal blocks. Background Technology

[0002] The automated production of traditional terminal blocks (consisting of a base shell, spring clips, toggle switches, and an upper shell) typically employs a series assembly line: the base shell is conveyed sequentially, the spring clips are installed, the toggle switches are installed, and finally the upper shell is installed.

[0003] Each step is performed sequentially, resulting in a long total assembly time for a single terminal block. If an error occurs in an intermediate step (such as installing a toggle switch or the upper casing), the assembled bottom casing and spring clips will also be scrapped, causing material waste. Summary of the Invention

[0004] In order to improve the problems of low assembly efficiency and scrapping of the entire unit due to single point of error in the prior art, this application provides an automated parallel assembly device for terminal blocks.

[0005] This application provides an automated parallel assembly device for terminal blocks, which adopts the following technical solution: An automated parallel assembly device for terminal blocks, comprising: The bottom shell feeding assembly is located at the first end of the equipment and is used to convey the bottom shell; The upper shell feeding assembly is located at the second end of the equipment and is used for synchronous conveying of the upper shell; The spring clip feeding and installation assembly is located on the bottom shell conveying path and is used to install the spring clips in the bottom shell; The toggle switch feeding and mounting assembly is located on the upper housing conveying path and is used to mount the toggle switch inside the upper housing. The bottom shell and upper shell assembly assembly is located in the middle of the equipment and is used to finally press and assemble the bottom shell with the spring clips installed and the upper shell with the toggle switch installed. The bottom shell feeding assembly, the upper shell feeding assembly, and the spring clip feeding and mounting assembly and the toggle switch feeding and mounting assembly all include a vibratory feeder; The bottom shell feeding assembly includes a first bottom shell conveying track and a second bottom shell conveying track. A bottom shell pushing assembly is provided between the first bottom shell conveying track and the second bottom shell conveying track. The bottom shell pushing assembly is used to push the continuously arranged bottom shells at intervals to the spring clip feeding and mounting assembly. The first drive assembly includes a first drive rod, a first reciprocating drive member, and a first forward / backward drive member; the first drive rod is provided with bottom shell clearance grooves at intervals along its length; the first forward / backward drive member is used to drive the first drive rod to move closer to or further away from the second bottom shell conveying track, so that the bottom shell is located in the bottom shell clearance groove during conveying and is disengaged from the bottom shell clearance groove before the first drive rod is reset; the first reciprocating drive member is used to drive the first drive rod to move back and forth along the conveying direction, and the distance of each movement is the distance between two adjacent bottom shells; The spring clip feeding and installation assembly includes a spring clip gripper and a first pressing member, wherein the first pressing member drives the spring clip gripper to press the spring clip into the bottom shell on the second bottom shell conveying track; The upper shell feeding assembly includes a first upper shell conveying track and a second upper shell conveying track. An upper shell pushing assembly is provided between the first upper shell conveying track and the second upper shell conveying track. The upper shell pushing assembly is used to push the continuously arranged upper shells at intervals to the toggle switch feeding and installation assembly. The second drive assembly includes a second drive rod, a second reciprocating drive member, and a second forward / backward drive member. The second drive rod has upper shell clearance grooves spaced apart along its length. The second forward / backward drive member drives the second drive rod to move closer to or further away from the second upper shell conveying track, such that the upper shell is located within the upper shell clearance groove during conveying and disengages from the upper shell clearance groove before the second drive rod resets. The second reciprocating drive member drives the second drive rod to reciprocate along the conveying direction, with each reciprocating movement being the distance between two adjacent upper shells. The toggle switch feeding and installation assembly includes a toggle switch gripper and a second pressing member. The second pressing member drives the toggle switch gripper to press the toggle switch into the upper shell on the second upper shell conveying track. The bottom shell and upper shell assembly includes an upper shell gripper and a third pressing member, the third pressing member driving the upper shell gripper to press the upper shell into the bottom shell on the second bottom shell conveying track.

[0006] By adopting the above technical solution, parallel operations on the bottom shell side (bottom shell feeding, spring clip installation) and the top shell side (top shell feeding, toggle switch installation) are achieved, shortening the total assembly time and increasing output per unit time. Stable material supply is achieved through a vibratory feeder, and precise and rhythmic conveying of the bottom shell and top shell is achieved by utilizing the intermittent movement of the first and second drive rods and the clearance groove structure. At the same time, stable pressing force is provided by the pressing components (first, second, and third pressing components) to ensure accurate installation of the spring clips, toggle switches, and top and bottom shells, thereby improving product consistency.

[0007] Optionally, the device further includes a bottom shell transfer track, which is connected to a first upper shell conveying track and a second upper shell conveying track at both ends, respectively. The bottom shell transfer track can only accommodate one bottom shell, and the conveying routes of the first upper shell conveying track and the second upper shell conveying track are arranged parallel to each other. The bottom shell pusher assembly includes: Two bottom-casing actuators, the pushing directions of the two bottom-casing actuators being perpendicular to each other; One of the bottom shell drivers is used to push the bottom shell of the bottom shell transfer track to the entrance of the second bottom shell conveying track, and the other bottom shell driver pushes the bottom shell into the second bottom shell conveying track; The first drive rod is used to drive the spaced-apart bottom shells to move intermittently along the second bottom shell conveyor track.

[0008] By adopting the above technical solution, the transfer track acts as a buffer, ensuring that only one bottom shell is pushed at a time, avoiding congestion caused by multiple bottom shells entering the next process simultaneously. The two perpendicular drives transfer the bottom shell smoothly and accurately from the first track to the parallel second conveying track through a "relay" method, realizing the right-angle conversion of the feeding path and the cycle control. Combined with the intermittent movement of the first drive rod, the bottom shell pushing assembly ensures that the bottom shells can move in a fixed interval (equal to the distance the drive rod moves each time) on the second conveying track, providing a stable workpiece position basis for the precise installation of the subsequent spring clips.

[0009] Optionally, the device also includes an upper shell flipping assembly, installed at the end of the second upper shell conveying track away from the upper shell pushing assembly; the upper shell flipping assembly includes a clamping platform and a flipping drive that drives the clamping platform to rotate 180°, the clamping platform accommodating only one upper shell at a time; the second drive rod pushes the unflipped upper shell into the clamping platform, while simultaneously pushing the flipped upper shell away from the clamping platform; the device also includes a third upper shell conveying track, into which the flipped upper shell is pushed.

[0010] By adopting the above technical solution, the upper shell is automatically rotated 180°, allowing it to enter the subsequent assembly process in the correct assembly posture (e.g., the opening direction matches the bottom shell). The rotation action and the upper shell conveying action are highly integrated. While the second drive rod pushes the new upper shell into the clamping platform, it uses the same power to push the rotated upper shell out of the platform. This "push-in and push-out" linkage design eliminates the need for an additional drive source and complex handling mechanism, resulting in a compact structure and smooth, efficient operation.

[0011] Optionally, the third upper shell conveying track is inclined downwards, and the upper shell moves downwards along the third upper shell conveying track under its own gravity; a transfer assembly is connected to the lower end of the third upper shell conveying track, the transfer assembly includes a transfer platform and a transfer drive, the transfer platform can only hold one upper shell at a time, and the transfer drive pushes the upper shell out of the transfer platform through a piston rod; a receiving platform is connected to the transfer platform, and the upper shell gripper is located above the receiving platform.

[0012] By adopting the above technical solution, the upper shell moves on the inclined track by its own gravity without the need for additional power, saving energy and making the conveying process smooth. The transfer component acts as a buffer and positioning device, receiving only one upper shell at a time, ensuring that the upper shell is accurately and controllably delivered to the predetermined picking position on the receiving platform.

[0013] Optionally, a slide is connected between the third pressing member and the upper shell clamping claw. The bottom shell and upper shell assembly also includes a translation rail, on which the slide is mounted. A moving member is provided on the translation rail, which is used to drive the slide to move above the receiving platform or above the second bottom shell conveying rail.

[0014] By adopting the above technical solution, the material picking position (above the receiving platform) and the pressing position (above the second bottom shell conveyor track) are separated. The slide and the translational track achieve physical isolation between the two actions of material picking and pressing, avoiding component interference and making the equipment layout more flexible and compact. After the gripper completes precise material picking on the stationary receiving platform, it moves horizontally to the top of the bottom shell for pressing. This "first position and grip, then translate and assemble" mode reduces the impact on the workpiece posture during movement and has higher positional accuracy than directly gripping and pressing on the conveyor line.

[0015] Optionally, an upper shell detection assembly is installed on the third upper shell conveying track. The upper shell detection assembly includes an upper shell detection part, a telescopic rod, a first driving component that drives the telescopic rod to extend and retract, and an upper shell detection control center. The first driving component and the upper shell detection part are both electrically connected to the upper shell detection control center. The telescopic rod is installed on one side of the inner wall of the third upper shell conveying track, and the third upper shell conveying track is connected to an upper shell receiving part. When the upper shell detection part reports a problem with the upper shell, the upper shell detection control center controls the telescopic rod to extend, pushing the upper shell into the upper shell receiving part.

[0016] By adopting the above technical solution, the quality of the upper shell is automatically inspected before assembly (e.g., missing materials, deformation, foreign objects, etc.). Once a defective product is detected, the rejection mechanism is immediately triggered to push it into the receiving section, saving time and material costs associated with subsequent operations such as installing toggle switches and pressing on the defective upper shell, thereby improving the overall effective utilization rate of the equipment.

[0017] Optionally, the second bottom shell conveying track is provided with a bottom shell detection unit, a flap, and a second driving component that drives the flap to rotate. The flap is rotatably mounted on the bottom of the second bottom shell conveying track, and the bottom shell is placed on the surface of the flap. The bottom shell detection unit and the second driving component are electrically connected to a bottom shell detection control center. When the bottom shell detection unit reports a problem with the bottom shell, the bottom shell detection control center controls the flap to rotate, causing the bottom shell to leave the second bottom shell conveying track.

[0018] By adopting the above technical solution, online quality inspection of the bottom shell, especially before the spring clips are installed, is realized. When a defect is found in the bottom shell, the defective product is directly dropped and separated from the track by rotating the flip plate. The operation is simple and reliable.

[0019] Optionally, a first push block is installed at intervals on the first drive rod, and the bottom shell clearance groove is provided on the first push block; an insertion rod is fixedly installed at the end of the first drive rod away from the bottom shell pushing assembly, and the insertion rod is used to insert into the inner hole of the bottom shell; when the first forward and backward drive component drives the first drive rod closer to the second bottom shell conveying track, the insertion rod is inserted into the inner hole of the bottom shell; when the first forward and backward drive component drives the first drive rod away from the second bottom shell conveying track, the insertion rod is withdrawn from the inner hole of the bottom shell; the bottom shell and the upper shell are pressed together and assembled by the insertion rod.

[0020] By adopting the above technical solution, after the insert rod is inserted into the inner hole of the bottom shell, the bottom shell is actively gripped and precisely positioned. Compared with simply relying on the track and push block, this "pin-type" positioning can completely eliminate the shaking or displacement that may occur during the movement of the bottom shell; in the final pressing process (when the bottom shell and upper shell assembly components of claim 1 are in operation), since the bottom shell is firmly fixed by the insert rod, the bottom shell will not shift when the upper shell is pressed. This ensures perfect alignment of the snap-fit, positioning post and other structures of the upper shell and the bottom shell, which greatly improves the pressing success rate and the robustness of the product structure.

[0021] Optionally, the device further includes an upper shell receiving component, the upper shell receiving component comprising: The receiving block is slidably mounted on the insertion rod; The conveyor plate is tilted, and its tilted upper end is connected to the receiving block; A reset spring is sleeved on the insertion rod, with one end connected to the receiving block; When the insert rod is inserted into the bottom shell, the receiving block compresses the return spring and avoids the upper shell, so that the upper shell and the bottom shell can be pressed together and assembled; when the upper shell is removed from the insert rod, the receiving block resets. When the bottom shell leaves the second bottom shell conveying track via the flap and the insertion rod is not inserted into the bottom shell, and the insertion rod moves to below the upper shell, the upper shell is placed on the receiving block and leaves the second bottom shell conveying track along the conveying plate.

[0022] By adopting the above technical solution, when the bottom shell is rejected by the flip-plate due to failure in inspection, the insertion rod will be in an unloaded state. At this time, the receiving component will automatically catch the top shell that was originally to be assembled with the missing bottom shell, and guide and collect it through the conveyor plate, preventing the top shell from falling and being damaged or jamming the equipment due to lack of pressure. When the bottom shell is normally inserted, the receiving block is compressed by the bottom shell, making room for pressing and ensuring that the top shell can be pressed smoothly with the bottom shell. After pressing, the return spring resets the receiving block, preparing for the next action. The structural design is highly integrated, and the action logic is clear.

[0023] Optionally, the conveyor plate is mounted on the receiving block via a rotating shaft, and the lower surface of the conveyor plate is always in contact with the first drive rod; the tilt angle of the conveyor plate is changed by sliding the receiving block, and when the receiving block compresses the reset spring and moves closer to the first drive rod, the downward tilt angle of the conveyor plate increases.

[0024] By adopting the above technical solution, the insertion rod is inserted into the bottom shell, the receiving block moves backward, and the conveyor plate rotates around the axis connecting it and the receiving block. Since the lower surface of the conveyor plate is always in contact with the first drive rod, when the receiving block approaches the first drive rod, the free end of the conveyor plate swings downward, increasing its tilt angle with the horizontal plane. Since the insertion rod has no bottom shell, the return spring moves the receiving block away from the first drive rod. The conveyor plate is pulled by the receiving block, and its lower surface still slides against the upper surface of the first drive rod, causing the free end of the conveyor plate to lift upward, reducing the tilt angle and making it more gradual. This facilitates the stable reception of the upper shell falling from the upper shell gripper or other mechanisms, and allows it to slide down smoothly.

[0025] In summary, this application includes at least one of the following beneficial effects: 1. By using parallel and independent production lines for the bottom shell and the top shell, synchronous pretreatment and final pressing are achieved, eliminating process waiting time; 2. Through independent production lines and online inspection and rejection mechanisms, local isolation of faulty workstations and early interception of defective products can be achieved.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 12 This application will be described in further detail.

[0029] This application discloses an automated parallel assembly device for terminal blocks. It aims to solve the problems of low efficiency and complete scrapping due to single-point errors in existing serial terminal block assembly. Generally, the device adopts a dual-path parallel layout with a central convergence: a bottom shell feeding assembly 100 is provided at the first end (e.g., the left end), and an upper shell feeding assembly 200 is provided at the second end (e.g., the right end). A spring clip feeding and installation assembly 300 is provided on the bottom shell conveying path for installing the spring clips into the bottom shell. A toggle switch feeding and installation assembly 400 is provided on the upper shell conveying path for installing the toggle switches inside the upper shell. A bottom shell and upper shell assembly assembly 500 is provided in the middle of the device for final pressing and assembling the bottom shell with spring clip installation and the upper shell with toggle switch installation. The bottom shell feeding assembly 100, the upper shell feeding assembly 200, the spring clip feeding and installation assembly 300, and the toggle switch feeding and installation assembly 400 all include a vibratory feeder 120, which enables orderly feeding.

[0030] Reference Figure 2 First, the pre-processing flow on the bottom shell side is described. The bottom shell feeding assembly 100 includes a first bottom shell conveying track 101 and a second bottom shell conveying track 102, which are arranged parallel to each other. The output end of the first bottom shell conveying track 101 is connected to a bottom shell transfer track 103, which can only accommodate one bottom shell. One end of the bottom shell transfer track 103 is connected to the second bottom shell conveying track 102.

[0031] Reference Figure 3 A bottom shell pushing assembly is provided between the first bottom shell conveying track 101 and the second bottom shell conveying track 102. The bottom shell pushing assembly includes two bottom shell drivers 110, and the pushing directions of the two bottom shell drivers 110 are perpendicular to each other. The vibrating feeder 120 organizes the scattered bottom shells into a queue with the ends connected and feeds them into the first bottom shell conveying track 101. When the first bottom shell enters the bottom shell transfer track 103, the first bottom shell driver 110 (e.g., a transverse cylinder) pushes the bottom shell to the push position near the entrance of the second bottom shell conveying track 102. Then, the second bottom shell driver 110 (e.g., a longitudinal cylinder) pushes the bottom shell into the second bottom shell conveying track 102.

[0032] Reference Figure 3A first drive assembly 600 is provided on the side of the second bottom shell conveying track 102. The first drive assembly 600 includes a first drive rod 601, a first reciprocating drive component 602 (a first reciprocating cylinder in this embodiment), and a first forward / backward drive component 603 (a first forward / backward cylinder in this embodiment). The first forward / backward cylinder is connected to a movable seat, and the first reciprocating cylinder is mounted on the movable seat. The first drive rod 601 is connected to the first reciprocating cylinder. A plurality of first push blocks 605 are installed at intervals along the length direction of the first drive rod 601, and each first push block 605 is provided with a bottom shell clearance groove 604. The first forward / backward cylinder is used to drive the first drive rod 601 to move closer to or away from the second bottom shell conveying track 102, so that the bottom shell is located in the bottom shell clearance groove 604 during conveying and disengages from the bottom shell clearance groove 604 before the first drive rod 601 resets. The first reciprocating cylinder is used to drive the first drive rod 601 to move back and forth along the conveying direction, and the distance moved each time is the design distance between two adjacent bottom shells. The specific operational logic is as follows: The first forward / reverse cylinder drives the first drive rod 601 to approach the second bottom shell conveying track 102, so that the bottom shell is located in the bottom shell clearance groove 604; the first reciprocating cylinder drives the first drive rod 601 forward one station, and the first push block 605 pushes the bottom shell sidewall through the clearance groove, so that all bottom shells move forward synchronously; then, the first forward / reverse cylinder drives the first drive rod 601 away from the second bottom shell conveying track 102, so that the first push block 605 disengages from the bottom shell; the first reciprocating cylinder drives the first drive rod 601 backward to reset; finally, the first forward / reverse cylinder drives the first drive rod 601 to approach the bottom shell again, so that the bottom shell re-enters the clearance groove, completing one conveying cycle. This is repeated to achieve intermittent step conveying of the bottom shell along the second bottom shell conveying track 102.

[0033] Along the second bottom shell conveying path, at the working station where the spring clip feeding and mounting assembly 300 is located, a spring clip gripper 301 and a first pressing member 302 (in this embodiment, a first pressing cylinder) are provided. When the bottom shell is conveyed to this station and positioned, the spring clip gripper 301 grips a spring clip from the discharge port of the vibratory feeder 120. The first pressing cylinder drives the spring clip gripper 301 to move downwards, accurately pressing the spring clip into the preset mounting groove of the bottom shell. The output track of the vibratory feeder 120, from which the spring clips are fed, is close to the second bottom shell conveying track 102. The spring clip gripper 301 needs to grip the spring clip onto the second bottom shell conveying track 102. The spring clip gripper 301 installs the spring clip onto the bottom shell through driven translational and vertical movements. The principle of translational and vertical movements is based on existing technology. Then, through the first pressing member 302, the spring clip and the bottom shell are completely pressed together and assembled.

[0034] After the spring clips are installed, the bottom shell continues to move forward along the second bottom shell conveyor track 102. A bottom shell detection assembly 1000 is installed on the second bottom shell conveyor track 102, located after the spring clip installation station and before the final pressing station.

[0035] Reference Figure 4 The bottom shell detection assembly 1000 includes a bottom shell detection unit 1001 (e.g., a machine vision camera), a flip plate 1002, and a second driving component (e.g., a rotary cylinder or rotary electromagnet for the flip plate 1002) that drives the flip plate 1002 to rotate. The flip plate 1002 is rotatably mounted on the bottom of the second bottom shell conveying track 102, and the bottom shell is normally placed on the upper surface of the flip plate 1002. Both the bottom shell detection unit 1001 and the second driving component are electrically connected to a bottom shell detection control center. When the bottom shell detection unit 1001 detects a defect in the bottom shell (e.g., misaligned spring clips or a broken bottom shell body), the bottom shell detection control center controls the second driving component to flip the flip plate 1002 downwards, causing the defective bottom shell to leave the second bottom shell conveying track 102 under gravity and fall into the collection box below. Subsequently, the flip plate 1002 resets. When the detection is qualified, the flip plate 1002 remains horizontal, and the bottom shell continues to move forward.

[0036] Reference Figure 5 Meanwhile, a synchronous pre-processing process is carried out on the upper shell side. The upper shell feeding assembly 200 includes a first upper shell conveying track 201 and a second upper shell conveying track 202, which are arranged parallel to each other. The pushing structure of its upper shell pushing assembly 210 is similar to that of the bottom shell side: the end of the first upper shell conveying track 201 is connected to an upper shell transfer track 203 that can only accommodate one upper shell. Two drives with mutually perpendicular pushing directions transfer the upper shells one by one from the first upper shell conveying track 201 to the second upper shell conveying track 202.

[0037] The second drive assembly 700 has a similar structure to the bottom shell side, including a second drive rod 701, a second reciprocating drive member 702 (second reciprocating cylinder) and a second forward and backward drive member 703 (second forward and backward cylinder). The second drive rod 701 is provided with upper shell clearance grooves 704 at intervals along its length direction. Its operation logic is the same as that of the first drive assembly 600, and it is used to drive the upper shell to intermittently step forward along the second upper shell conveying track 202.

[0038] Reference Figure 5At the work station where the toggle switch feeding and installation assembly 400 is located, a toggle switch gripper 401 and a second pressing component 402 (in this embodiment, a second pressing cylinder) are provided. When the upper shell is conveyed to this work station, the toggle switch gripper 401 picks up the toggle switch from the vibrating feeder 120, and the second pressing cylinder drives the toggle switch gripper 401 to press the toggle switch into the corresponding slot inside the upper shell. After the toggle switch installation is completed, the upper shell continues to move forward along the second upper shell conveying track 202.

[0039] Reference Figure 5 At the end of the second upper shell conveying track 202 (the end furthest from the upper shell pusher assembly 210), an upper shell flipping assembly 800 is installed. This assembly includes a clamping platform 801 and a flipping drive 802 (e.g., a rotary cylinder) that rotates the clamping platform 801 180°. The clamping platform 801 accommodates only one upper shell at a time. When an upper shell with a toggle switch installed is pushed into the clamping platform 801 by the second drive rod 701, the clamping platform 801 clamps the upper shell, and the flipping drive 802 rotates the platform 180°, thereby adjusting the upper shell's orientation to match the bottom shell's assembly direction (e.g., changing the upper shell opening from upward to downward). Subsequently, the second drive rod 701 pushes the next unflipped upper shell into the clamping platform 801, and this thrust simultaneously pushes out the flipped upper shell from the clamping platform 801.

[0040] Reference Figure 6 and Figure 7 The upper shell clamping platform 801 is connected to a third conveying track, and the upper shell enters the third upper shell conveying track 803. A transfer assembly 810 is connected to the lower end of the third upper shell conveying track 803. This transfer assembly 810 includes a transfer platform 811 and a transfer drive component 812 (e.g., a transfer cylinder). The transfer platform 811 can only hold one upper shell at a time. After good upper shells enter the transfer platform 811 one by one, the transfer cylinder pushes the upper shell out of the transfer platform 811 through its piston rod, pushing it onto a receiving platform 813 connected to the transfer platform 811. An upper shell gripper 501 is provided above the receiving platform 813 for subsequent gripping.

[0041] Furthermore, refer to Figure 8 and Figure 9The third upper shell conveying track 803 is inclined downwards, and the upper shell slides downwards along the track under its own gravity. An upper shell detection assembly 900 is installed on the third upper shell conveying track 803. This assembly includes an upper shell detection unit 901 (e.g., a vision sensor), a telescopic rod 902, a first driving component 903 (e.g., a rejection cylinder) that drives the telescopic rod 902 to extend and retract, and an upper shell detection control center. The first driving component 903 and the detection unit are electrically connected to the upper shell detection control center. The telescopic rod 902 is installed on one side of the inner wall of the third upper shell conveying track 803, which is connected to an upper shell receiving unit 904. When the upper shell detection unit 901 reports a defect in the upper shell (e.g., a missing toggle switch or shell deformation), the upper shell detection control center controls the rejection cylinder to drive the telescopic rod 902 to extend, pushing the defective upper shell into the upper shell receiving unit 904; good shells continue to slide down.

[0042] Reference Figure 10 Finally, the final pressing and assembly process of the bottom shell and the top shell is described. A finished product discharge track 104 is connected to the end of the second bottom shell conveying track 102, i.e., the pressing station, and the finished product discharge track 104 is inclined. A plug 606 is fixedly installed at one end of the first drive rod 601 near the finished product discharge track 104. This plug 606 is used to insert into the inner hole carried on the side of the bottom shell. Since the plug 606 is fixedly installed on the first drive rod 601, when the first advance / retractable cylinder drives the first drive rod 601 closer to the second bottom shell conveying track 102, the plug 606 is inserted into the inner hole of the bottom shell, achieving active gripping and stable fixation of the bottom shell; when the first advance / retractable cylinder drives the first drive rod 601 away from the second bottom shell conveying track 102, the plug 606 is withdrawn from the inner hole of the bottom shell.

[0043] Reference Figure 7 and Figure 8The bottom shell and upper shell assembly 500 includes an upper shell gripper 501, a third pressing member 502 (in this embodiment, a third pressing cylinder), a slide 503, a translational track 504, and a moving member 505 (e.g., a rodless cylinder or a lead screw motor). Specifically, a slide 503 is connected between the third pressing cylinder and the upper shell gripper 501. The slide 503 is mounted on the translational track 504, and the moving member 505 is provided on the translational track 504 to drive the slide 503 to move. Initially, the slide 503 is located above the receiving platform 813, and the upper shell gripper 501 descends to grab the upper shell on the receiving platform 813. Subsequently, the moving member 505 drives the slide 503 to move along the translational track 504, so that the upper shell gripper 501 is located above the second bottom shell conveying track 102, that is, directly above the pressing station. Then, the third pressing cylinder drives the upper shell gripper 501 to move downwards, pressing the upper shell against the bottom shell that has been fixed by the insertion rod 606, completing the final pressing assembly. After pressing, the first forward and backward cylinder drives the first drive rod 601 away from the second bottom shell conveying track 102, and the insertion rod 606 withdraws from the inner hole of the finished product. The upper shell gripper 501 is released, and the first reciprocating cylinder drives the first drive rod 601 to step forward again, pushing the finished product out of the pressing station.

[0044] In addition, refer to Figure 11 and Figure 12 To address the issue of the upper shell falling and getting damaged or jammed during pressing when the bottom shell is removed, this equipment also includes an upper shell receiving assembly 1100 on the insertion rod 606. This upper shell receiving assembly 1100 includes a receiving block 1101, a conveying plate 1102, and a return spring 1103. The receiving block 1101 is slidably mounted on the insertion rod 606. The conveying plate 1102 is inclined, with its inclined upper end connected to the receiving block 1101. The return spring 1103 is sleeved on the insertion rod 606, with one end connected to the receiving block 1101. When the insertion rod 606 is normally inserted with the bottom shell, the bottom shell end face pushes the receiving block 1101 to compress the return spring 1103, causing the receiving block 1101 to avoid the upper shell, creating space for the pressing of the upper and bottom shells. After the upper shell leaves the insertion rod 606, the receiving block 1101 returns to its original position under the action of the return spring 1103.

[0045] When the bottom shell fails the inspection and leaves the second bottom shell conveying track 102 via the flip plate 1002, and the insertion rod 606 is not inserted into the bottom shell, and the insertion rod 606 moves to the bottom shell, the upper shell is placed on the receiving block 1101 and leaves the second bottom shell conveying track 102 along the inclined conveyor plate 1102 and enters the recycling channel.

[0046] Furthermore, referring to Figure 12The conveyor plate 1102 is mounted on the receiving block 1101 via a rotating shaft. The lower surface of the conveyor plate 1102 is always in contact with the upper surface of the first drive rod 601. The tilt angle of the conveyor plate 1102 can be changed by sliding the receiving block 1101: when the receiving block 1101 compresses the reset spring 1103 and approaches the fixed block, the downward tilt angle of the conveyor plate 1102 increases, which helps the finished product to be smoothly removed after pressing; when the receiving block 1101 resets and moves away from the fixed block, the downward tilt angle of the conveyor plate 1102 decreases, which is conducive to stable reception and guiding the upper shell to slide down.

[0047] At this point, the equipment has completed a full work cycle. Through parallel and independent pre-processing of the bottom and top shells, online detection to remove defective products, and precise positioning and error-proofing recycling mechanisms at the final pressing station, this equipment significantly improves the assembly efficiency of terminal blocks while reducing material waste and production costs.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
