Description

Technical Field

[0001] This utility model relates to the technical field of dispensing machines, specifically to an assembly box dispensing and pressing molding machine. Background Technology

[0002] In the manufacturing process of some boxes, sealing the lid and the shell with glue is a crucial step. For example, in the field of battery manufacturing, especially in the production of hard-shell batteries, the sealing performance of the assembled box shell and cover is an important indicator to ensure the battery's sealing and structural integrity.

[0003] Currently, the common method for sealing housings with covers is to clamp and process them individually. Specifically, operators or automated equipment need to place each housing in a dedicated fixture, clamp and fix it, then apply adhesive to the opening of the housing or the cover, initially installing the cover onto the housing, and finally completing the sealing operation (such as applying adhesive and pre-positioning) by pressing the cover. Afterwards, the housing needs to be removed from the fixture, transported, positioned, and installed separately at the next process station (such as laser welding or pressure curing) for final processing. This "one-clamp, one-release" cyclical pattern constitutes the core rhythm of traditional production lines.

[0004] However, this traditional single-piece flow production method is inefficient. Each box requires independent clamping, unclamping, and loading / unloading processes, with a significant amount of time wasted on repetitive positioning, transfer, and waiting, severely restricting the overall production cycle and failing to meet the high efficiency demands of large-scale manufacturing. Furthermore, when applying adhesive to the contact surface between the cover and the shell, it is difficult to apply adhesive at the opening edge when the shell to be assembled has a thin wall thickness, such as less than 2.5mm. To ensure a seal, many covers typically have protruding rings that extend into the shell. These rings are inserted into the shell opening for positioning before being pressed and sealed. When the cover is initially placed on top of the shell, adhesive is easily forced into the shell. While adhesive application to the cover is easy to implement with equipment, the assembly structure is relatively complex and prone to adhesive seepage into the shell. When applying adhesive after the shell and cover are pre-installed, the gap between them is generally no more than 5mm, and often only about 3mm. This severely limits the adhesive application width and operating space, making it difficult for existing dispensing equipment to achieve 360° circular dispensing, especially for square assembly boxes. For this type of structure, the current method typically involves applying adhesive to the cover and simultaneously bonding the shell opening and part of the inner wall as one side of the cover is inserted into the shell. This method allows some adhesive to seep into the shell, potentially affecting the properties of the internal materials and thus the overall product quality. Furthermore, existing equipment usually only performs a single compression and sealing before removal, easily leading to inadequate sealing during subsequent vacuuming of the assembly box. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this application is to provide an assembly box dispensing and pressing molding machine that can achieve 360° precise dispensing of adhesive into the gaps between the pre-assembled shell and cover plate, thereby preventing adhesive from seeping into the shell and ensuring a stable sealing effect.

[0030] Compared with the prior art, the beneficial effects of this utility model are as follows: When applying adhesive to seal the shell and cover of the assembly box, the control cabinet sets the equipment parameters and arranges the control components to automatically move, apply adhesive, and maintain pressure on the assembly box to be assembled. This is achieved by controlling the dispensing slide, the peristaltic dispensing assembly, and the pressure-holding assembly. The dispensing carrier can position multiple assembly boxes to be assembled, facilitating continuous and rapid dispensing and sealing operations, thus solving the problem of low production efficiency in traditional production lines. The dispensing slide allows for movement of the dispensing carrier, enabling switching between assembly, dispensing, and pressure-holding processes. The peristaltic dispensing assembly enables 360° circumferential dispensing and sealing of the openings of each assembly box on the dispensing carrier. This achieves the goal of rapid sealing after conventional glue application, avoiding the problem of glue curing due to prolonged contact with air. It also improves the efficiency and accuracy of batch glue application, enabling precise dispensing in small spaces. In particular, with the addition of the pressure-holding assembly, all dispensed and initially sealed assembly boxes on the dispensing carrier can be batch-pressed again, allowing the glue to cure between the shell and the cover under certain pressure. This ensures the stability of the assembly box's sealing effect and avoids air leakage caused by sealing problems during later vacuuming. Attached Figure Description

[0032] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0035] like Figure 1 As shown, an assembly box dispensing and pressing molding machine is used to apply glue and press and seal assembly boxes 100 that need to be glued and sealed between the connecting surfaces of the housing 110 and the cover plate 120. It mainly includes a worktable 1, a dispensing slide 2 mounted on the worktable 1, a detachable dispensing carrier 8 mounted on the dispensing slide 2, a peristaltic dispensing assembly 5 mounted on the worktable 1 for applying glue and pressing the assembly boxes 100 to be sealed on the dispensing carrier 8, a pressure holding assembly 4 for pressing and holding all assembly boxes 100 after initial pressing and sealing for a certain period of time, and a control cabinet 6. The workbench 1 serves as the basic carrier, providing support and positioning for other components. The dispensing carrier 8 is used to install and position the assembly box 100 to be assembled, ensuring it remains in a designated position during the application and pressing processes via the peristaltic dispensing assembly 5. The dispensing slide 2 moves the dispensing carrier 8, moving it below the peristaltic dispensing assembly 5 when adhesive application and pressing are required, and below the pressure-holding assembly 4 when pressure holding and pressing are required. This movement of the dispensing carrier 8 completes the assembly process. The assembly box 100 consists of three processes: dispensing, pressing, and holding pressure. The peristaltic dispensing assembly 5 is used to perform 360° circumferential dispensing and pressing and sealing on the open end of the housing 110 of the assembly box 100 on the dispensing carrier 8. The holding pressure assembly 4 is used to continuously press the cover plate 120 on the assembly box 100 downward for a certain period of time. The control cabinet 6 can set the equipment parameters and control the arrangement of components, so that the dispensing slide 2, the peristaltic dispensing assembly 5 and the holding pressure assembly 4 can automatically move, dispense, and hold pressure on the assembly box 100 to be assembled.

[0036] After structural improvements, the dispensing carrier 8 can simultaneously position multiple assembly boxes 100 to be assembled. This allows for continuous glue application and clamping of each assembly box 100 during the sealing process. After a single assembly box 100 is glued and clamped, the peristaltic dispensing assembly 5 can move directly to process the next assembly, thus saving the time wasted during loading and unloading when two assembly boxes 100 are being processed using the peristaltic dispensing assembly 5. Furthermore, after initial glue application and clamping, all assembly boxes 100 on the same set of dispensing carriers 8 can be processed within a limited time. The dispensing slide 2 moves quickly to the bottom of the pressure holding component 4. The pressure holding component 4 continuously presses the cover plates 120 of all assembly boxes 100 against the housing 110 for a certain period of time, so that the cover plates 120 can cure the adhesive under pressure. By performing initial pressing and bonding immediately after dispensing, and then moving and pressing and holding the pressure for a second time within an effective time, the problem of insufficient sealing after curing that exists in the process of initial pressing and bonding immediately after dispensing can be effectively avoided. This can effectively reduce the probability of local leakage at the bonding point due to sealing problems when performing vacuuming and other operations on the product.

[0037] In this process, after the housing 110 and cover plate 120 are installed on the dispensing carrier 8, the lower part of the cover plate 120 is the opening for initial insertion into the housing 110, ensuring that the gap between the housing 110 and the cover plate 120 is generally no more than 4mm. The peristaltic dispensing assembly 5 performs 360° circular dispensing on the opening end of each assembly box 100 housing 110, ensuring the adhesive is evenly distributed on the top wall of the opening end of the housing 110. After dispensing, a slow, tight seal is applied. This slow pressure prevents impact when the cover plate 120 comes into contact with the adhesive, thus ensuring that the adhesive does not splash and contaminate the work surface, nor does it seep into the inner cavity of the housing 110 along the connection between the cover plate 120 and the housing 110. It also ensures the adhesive is evenly distributed between the two, resulting in better sealing of the assembly box 100. Throughout this process, the problem of low production efficiency in traditional single-piece flow production methods is effectively solved. Even when assembling thin-walled assembly boxes 100, the final position of the glue and its sealing performance can be guaranteed.

[0038] Further improvements include, for example Figure 2 As shown, the dispensing slide 2 includes an electric linear module 22 mounted on the worktable 1, a movable base 23 mounted on the electric linear module 22, and a plurality of position sensors 21 mounted on one side of the electric linear module 22. The dispensing carrier 8 is detachably mounted on the movable base 23, and the dispensing carrier 8 moves back and forth along the electric linear module 22 via the movable base 23.

[0039] The dispensing slide 2 adopts an electric linear module 22 structure with a movable base 23. With the help of multiple position sensors 21 located on one side of the electric linear module 22, the movable base 23 can be moved back and forth quickly and positioned at a specified location. The movable base 23 enables the dispensing carrier 8 to be detachably and quickly installed. When the dispensing carrier 8 needs to be moved at the assembly station, the dispensing + pressing station of the peristaltic dispensing component 5, and the secondary pressing station of the pressure holding component 4, it can achieve rapid and accurate displacement, thereby effectively improving production efficiency.

[0040] Further improvements include, for example Figure 3 and Figure 4 As shown, the dispensing carrier 8 includes a mold base 81, a plurality of storage slots 82 provided on the mold base 81, and a clamping component 83 for clamping and positioning the assembly box 100 housing 110 placed in the storage slots 82. After the assembly box 100 housing 110 to be assembled is placed in the storage slots 82, it is clamped and fixed by the clamping component 83.

[0041] When installing and positioning the assembly box 100, the housing 110 is placed into each storage slot 82. Then, the housing 110 in each storage slot 82 is pressed and positioned by the clamping component 83. The operator can then move multiple assembly boxes 100 in a concentrated manner using the dispensing carrier 8. When the dispensing carrier 8 with the assembly box 100 is installed on the moving base 23 for processing, the operator can fill and fix the assembly box 100 on the next dispensing carrier 8. After the assembly box 100 on the equipment is assembled, the entire dispensing carrier 8 can be removed for quick replacement of the next one. Then, the completed assembly box 100 on the dispensing carrier 8 is removed for reloading. Multiple housings 110 to be assembled are limited by the receiving slots 82 and then clamped and fixed onto the mold base 81 by the clamping component 83. They then enter the production equipment for centralized operation. This solves the problems of low production efficiency and difficulty in ensuring positioning accuracy after multiple processes in the traditional single-piece production method, resulting in stable final packaging quality, high yield, effectively improved production efficiency, and saved loading and unloading time. The overall structure is simple and easy to operate. While multiple receiving slots 82 are used on the mold base 81, only one clamping component 83 is equipped to clamp and position the housings 110 within the receiving slots 82. During the clamping operation, rapid batch positioning can be achieved, resulting in higher operational efficiency.

[0042] The mold carrier 81 includes a base plate 811, a back plate 813 on the base plate 811, and a locking block 812 on the back plate 813. The storage slot 82 is provided on the locking block 812. The back plate 813 has a locking block 812 at both the upper and lower ends, and the locking block 812 is provided with a plurality of storage slots 82 evenly spaced.

[0043] The base plate 811 and back plate 813 are generally L-shaped. The back plate 813 serves both as a stop and as a positioning element for the locking block 812, allowing the height of the locking block 812 and the storage slot 82 to be fixed arbitrarily. To ensure the stability of the housing 110, a locking block 812 with a storage slot 82 is fixed at both the top and bottom of the back plate 813. When the housing 110 is placed into the storage slot 82, the top and bottom ends are limited, thus ensuring the positioning stability and accuracy of the elongated housing 110 even with a shorter length of the storage slot 82, and preventing tilting.

[0044] A further improvement is made in that a quick positioning component 9 is provided between the mold carrier 81 and the movable base 23, and the mold carrier 81 is detachably placed on the mold carrier 81 through the quick positioning component 9; the quick positioning component 9 includes a plurality of limiting blocks 92 spaced apart on the upper end of the movable base 23 and quick positioning protrusions 91 provided on the side of the base plate 811, and the mold carrier 81 is quickly limited and fixed by inserting the quick positioning protrusions 91 between the limiting blocks 92.

[0045] When placing the entire dispensing carrier 8 onto the movable base 23, conventional structures require a clamping mechanism for positioning, resulting in complex structures and cumbersome assembly and disassembly. This application utilizes a quick-positioning component 9 for rapid detachable connection, effectively avoiding the problem of not being able to quickly replace the dispensing carrier 8 in batches during production. This significantly improves production efficiency, saves loading and unloading time, and features a simple overall structure and easy operation. Specifically, several limiting blocks 92 in the quick-positioning component 9 are installed on the movable base 23, forming a horizontal limit through the combination of multiple limiting blocks 92. A quick-positioning protrusion 91 is formed on the side of the base plate 811. The carrier 81 can be quickly positioned and fixed by inserting the quick-positioning protrusion 91 between the limiting blocks 92. During the entire assembly and disassembly process, the dispensing carrier 8 simply needs to be placed directly onto the movable base 23 from top to bottom, with the quick-positioning protrusion 91 positioned between two limiting blocks 92 to achieve automatic positioning and fixation. Furthermore, due to the large overall weight of the dispensing carrier 8, there will be no shaking or displacement after positioning.

[0046] A further improvement is made in that the side of the limiting block 92 is provided with a guide surface 10, the bottom of the base plate 811 is provided with two guide rails 11, and the upper ends of the base plate 811 are also provided with handles 12.

[0047] To facilitate the rapid positioning of the protrusion 91 into the space between the two limiting blocks 92, a guide surface 10 is provided on the side of the limiting blocks 92. When the base plate 811 is placed on the upper surface of the movable base 23, it can be quickly installed within a wider lateral range, thus solving the problem of alignment difficulties during installation. Two long guide rails 11 are provided at the bottom of the base plate 811. These guide rails provide positioning and guidance when placed on an external operating table; furthermore, they prevent adhesion issues at the bottom, ensuring the flatness of the contact surface during repeated assembly and avoiding unevenness after installation. The entire dispensing carrier 8 is made of metal plate, allowing for higher precision in various mechanisms and the storage slot 82. It can also be positioned by its own weight, and the handles 12 on both sides enable rapid movement, especially improving safety and speed of replacement when disassembling and loading the mold base 81.

[0048] A further improvement based on any of the above embodiments is that the pressing assembly 83 includes a driving device 832 disposed on the mold base 81 and a pressure rod 831 that moves back and forth via the driving device 832; the driving device 832 includes a fixed base 8321 and a driver 8322 disposed on the fixed base 8321, and the middle of the pressure rod 831 is fixed on the driver 8322.

[0049] The drive unit 832 is fixed to the base plate 811, while the pressure rod 831 is installed in front of the storage slot 82 via the drive unit 832. When the housing 110 needs to be disassembled, the pressure rod 831 moves away from the storage slot 82 via the drive unit 832. After the housing 110 is installed, the drive unit 832 pushes the pressure rod 831 forward, so that the pressure rod 831 presses against the outside of the battery housing 110, thus clamping it between it and the storage slot 82, making clamping simpler and more convenient. The drive unit 8322 uses a push-pull quick-clamp clamp, making it more convenient and faster to move the pressure rod 831.

[0050] A further improvement based on any of the above embodiments is that a supporting sliding device 13 is symmetrically provided on both sides of the driving device 832, and the pressure rod 831 is fixed on the supporting sliding device 13; the supporting sliding device 13 includes a slide rail 132 and a slide seat 131 provided on the slide rail 132, and the pressure rod 831 is fixed on the slide seat 131.

[0051] When the length of the pressure rod 831 is large, it is prone to tilting or wobbling, causing one end to fail to clamp the housing 110. Therefore, a support sliding device 13 is symmetrically installed on both sides of the drive device 832. The support sliding device 13 ensures that the pressure rod 831 moves smoothly back and forth while avoiding tilting or wobbling at both ends, thus ensuring a stable clamping effect of the pressure rod 831 on the housing 110 in each storage slot 82. The support sliding device 13 consists of a slide rail 132 and an L-shaped slide block 131 mounted on the slide rail 132. The pressure rod 831 is fixed on the slide block 131. When the pressure rod 831 needs to move back and forth, it can move along the slide rail 132 via the slide block 131, ensuring both the accuracy of the movement trajectory and the stability during the clamping process.

[0052] A further improvement is made by providing a flexible silicone strip 14 at the front end of the pressure rod 831. The front end of the pressure rod 831 presses the housing 110 tightly through the flexible silicone strip 14, which can prevent damage to the housing 110. In addition, the soft material allows it to deform and automatically adapt to the slight dimensional differences of each housing 110. This ensures that even with tolerances, each assembly box 100 can be clamped evenly and reliably without the risk of loosening or over-tightening, thereby guaranteeing the consistency of batch processing.

[0053] Further improvements include, for example Figures 5-7 As shown, the peristaltic dispensing assembly 5 includes a frame 55 mounted on the worktable 1, an electric slide 54 mounted on the frame 55, a dispensing machine 53 mounted on the electric slide 54, a pressure plate device 52, and a dispensing device 51. The dispensing machine 53, the pressure plate device 52, and the dispensing device 51 move synchronously laterally via the electric slide 54. The discharge end of the dispensing machine 53 is connected to the dispensing device 51. The glue supplied by the dispensing machine 53 is discharged through the dispensing device 51 and rotates 360° along the opening end of the assembly box 100 housing 110 to be glued. After glue application, the cover plate 120 of the assembly box 100 is pressed by the pressure plate device 52.

[0054] The peristaltic dispensing assembly 5 is installed on the workbench 1 with the overall supply frame 55 positioned above the dispensing slide 2. The dispensing machine 53, the pressure plate device 52, and the dispensing device 51 all move laterally via the electric slide 54. The inlet of the dispensing machine 53 is connected to the glue via a flexible tube such as a silicone tube, and the outlet is connected to the dispensing device 51 via a flexible tube. During dispensing, the dispensing machine 53 controls the amount of glue dispensed, and the dispensing device 51 rotates 360° along the opening of the assembly box 100 housing 110 to be dispensed, completing a precise dispensing operation. After dispensing, the pressure plate device 52 slowly presses the glue, thus completing the application of glue and the closure of the cover plate 120 and the housing 110. The entire operation is simple and convenient.

[0055] A further improvement is made to the pressure plate device 52, which includes a connecting seat 523 on one side of the electric slide table 54, a pressing cylinder 522 on the connecting seat 523, and a first pressure plate 521 at the lower end of the pressing cylinder 522.

[0056] The pressing cylinder 522 is mounted on one side of the electric slide table 54 via the connecting seat 523. The electric slide table 54 can be moved. After the glue application is completed, the first pressure plate 521 can be pressed down on the cover plate 120 by moving the electric slide table 54. During operation, since the connecting seat 523 is not integrated with the glue dispensing device 51, it does not affect the glue application operation of the next glue dispensing device 51.

[0057] A further improvement is made to the dispensing device 51, which includes a lifting cylinder 512 on one side of the electric slide table 54, a rotary motor 513 on the piston rod of the lifting cylinder 512, a rotating seat 514 on the rotating shaft of the rotary motor 513, and an L-shaped dispensing pen 511 on the rotating seat 514. The L-shaped dispensing pen 511 is rotated by the rotary motor 513.

[0058] When adhesive needs to be applied between the housing 110 and the cover plate 120, the lifting cylinder 512 moves the rotary motor 513 downward, so that the adhesive dispensing end of the L-shaped dispensing pen 511 on the rotating seat 514 is located on the horizontal plane of the gap between the housing 110 and the cover plate 120. Then, the electric slide table 54 moves the L-shaped dispensing pen 511 to the space between the cover plates 120 of the first assembly box 100, and then, in conjunction with the dispensing slide table 2, applies adhesive to one side. After the first side is coated, the rotary motor 513 is activated to rotate the rotary seat 514. The base 514 rotates 90°, causing the L-shaped dispensing pen 511 to rotate 90° as a whole, while ensuring that the dispensing nozzle position remains unchanged. Then, it works with the electric slide 54 to apply glue to the second side. After rotating the L-shaped dispensing pen 511 again, it applies glue to the subsequent sides. The entire operation can be completed simply by moving the electric slide 54 and the dispensing slide 2 relative to each other, making the operation simpler and more convenient. It can also achieve right-angle turning glue application. When the assembly box 100 is polygonal, the rotation angle can also be set for control.

[0059] A further improvement based on the above embodiment is that a correction rod 16 is provided on one side of the rotating seat 514, and the correction rod 16 is provided with a waist-shaped hole 17, so that the replaced L-shaped dispensing pen 511 can be quickly positioned through the correction rod 16.

[0060] When the L-shaped dispensing pen 511 needs to be replaced, although the insertion and removal speed between the L-shaped dispensing pen 511 and the hose is very fast, the dispensing position accuracy requirement is high and the pipeline also needs to be kept smooth. Therefore, the downtime needs to be kept as short as possible. If there is no calibration rod 16, manual calibration is required, which takes a long time. If the calibration is not completed in a short time, the hose will become blocked due to prolonged lack of flow or glue will flow onto the operating table. After adding the calibration rod 16 with the waist-shaped hole 17, in normal working condition, the calibration rod 16 can be slid upward through the waist-shaped hole 17 and locked in place, thus not affecting the operation of the L-shaped dispensing pen 511. When the L-shaped dispensing pen 511 needs to be replaced and the dispensing port needs to be quickly calibrated, simply loosen the locking screw, move the calibration rod 16 downward to the bottom, and then align the end of the L-shaped dispensing pen 511 with the calibration center point on the lower side of the calibration rod 16 to achieve quick calibration. The entire calibration process can be completed above the glue receiving groove 3, thus ensuring the smoothness of the glue and improving the efficiency of the L-shaped dispensing pen 511 dispensing port positioning.

[0061] Further improvements include, for example Figure 5 As shown, a limiting box 7 for placing glue bottles is also provided on one side of the electric slide table 54.

[0062] A limiting box 7 for placing glue bottles is fixed on one side of the electric slide table 54. When applying glue, the glue bottle can be fixed by simply placing it in the limiting box 7. The dispensing machine 53 and the glue bottle are connected by a hose. When the peristaltic dispensing component 5 needs to apply glue, the glue bottle can move left and right synchronously. It is also simpler and more convenient to replace the glue.

[0063] Further improvements include, for example Figures 6-7 As shown, the workbench 1 is also provided with a glue receiving groove 3, which is located below the L-shaped glue dispensing pen 511 in the initial position.

[0064] Since the peristaltic dispensing assembly 5 applies glue by injecting glue, its delivery pipe is a small-diameter flexible tube, with an inner diameter generally not exceeding 2mm. The end size of the L-shaped dispensing pen 511 is even smaller, leading to blockage problems even with short periods of non-flow. Product replacement inevitably involves a certain interval; if no glue flows out during this time, it can easily cause glue not to be dispensed during subsequent applications. Therefore, to ensure the fluidity of the pipe and the accuracy of dispensing, the L-shaped dispensing pen 511 needs time to dispense glue when changing materials. The addition of the glue receiving groove 3 allows the L-shaped dispensing pen 511 to continue dispensing glue even in standby mode, thus ensuring the smooth flow of the entire pipe and the L-shaped dispensing pen 511, as well as the cleanliness of the work surface, preventing glue spillage and contamination.

[0065] Further improvements include, for example Figure 7 As shown, the pressure holding assembly 4 includes a pressure holding cylinder 42 vertically mounted on the frame 55 and a second pressure plate 41 located at the lower end of the pressure holding cylinder 42. The second pressure plate 41 is located above the dispensing slide table 2. After the assembly box 100 is initially pressed by the pressure plate device 52, the pressure holding cylinder 42 controls the second pressure plate 41 to move downward and then performs a second pressure holding and sealing for a certain period of time.

[0066] The bottom of the pressure-holding cylinder 42 is mounted on the frame 55, and its piston rod extends downward. The second pressure plate 41 is mounted on the piston rod of the pressure-holding cylinder 42. When the dispensing carrier 8 moves to directly below the second pressure plate 41 via the dispensing slide 2, the pressure-holding cylinder 42 controls the second pressure plate 41 to move downward, thereby achieving a continuous pressure-holding and sealing of the assembly box 100 after initial compression for a certain period of time. This allows the housing 110 and cover plate 120 of the assembly box 100 to achieve adhesive curing and sealing under pressure, preventing the cover plate 120 from being misaligned due to reverse force before the adhesive has cured.

[0067] A further improvement is made in that the bottom of the first pressure plate 521 and the second pressure plate 41 are provided with downward protruding rubber blocks 15, the bottom of the first pressure plate 521 is provided with one of the rubber blocks 15, and the number of the rubber blocks 15 at the bottom of the second pressure plate 41 is the same as that of the storage groove 82.

[0068] When the cover plate 120 is pressed by the first pressure plate 521 and the second pressure plate 41, the rubber pressure block 15 protruding downward from the bottom contacts the cover plate 120, which can prevent surface damage to the cover plate 120 due to rigid contact. The first pressure plate 521 has one rubber pressure block 15 at its bottom, while the second pressure plate 41 has the same number of rubber pressure blocks 15 as the storage groove 82. By using multiple rubber pressure blocks 15 to maintain pressure on multiple assembly boxes 100 one by one, the pressure holding effect of each assembly box 100 can be made more uniform and stable.

[0069] Meanwhile, two guide rods 43 are provided between the second pressure plate 41 and the frame 55, and the guide rods 43 are symmetrically arranged on both sides of the pressure holding cylinder 42.

[0070] The guide rod 43 is guided by the combination structure of the guide rod and the guide sleeve, which makes the second pressure plate 41 more flat when it is holding pressure. Even if only the outermost storage slot 82 on the dispensing carrier 8 is equipped with the assembly box 100, it will not tilt during the holding pressure.

[0071] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
