Description

Technical Field

[0001] This application relates to the field of needle ejection machine technology, and in particular to a double-tablet needle ejection device and system. Background Technology

[0002] In the existing technology, the most widely used is the semi-automatic needle ejection equipment. It usually has only one workstation for needle ejection and insertion. Therefore, after the needle ejection or insertion is completed, the equipment needs to be paused to remove the loaded material box after the needle is ejected or inserted before restarting the equipment to perform the next round of needle ejection or insertion. During the pause of the equipment, no needle ejection or insertion operation is performed, which makes the overall needle ejection and insertion efficiency of the equipment relatively low. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a needle ejection device and system capable of alternating needle ejection at two stations, thereby improving the efficiency of needle ejection.

[0004] A dual-table unloading needle device according to a first aspect embodiment of this application includes a worktable, the worktable having a first station, a second station, and a working area, the first station and the second station being respectively located at opposite ends of the worktable, and the working area being located between the first station and the second station; a driving assembly disposed on the worktable; and a feeding assembly including a first carrier plate, a second carrier plate, and a connecting plate, the first carrier plate being located at one end of the connecting plate near the first station, and the second carrier plate being located at one end of the connecting plate near the second station. The driving assembly is used to drive the needle in a horizontal direction. The connecting plate drives the first carrier plate to reciprocate between the first station and the working area, and also drives the second carrier plate to reciprocate between the second station and the working area. The first and second carrier plates are used to load fixtures. When the first carrier plate moves to the working area, the second carrier plate is located at the second station, and when the second carrier plate moves to the working area, the first carrier plate is located at the first station. A needle loading and unloading assembly is located above the working area and is used to perform needle loading or unloading operations on the fixture.

[0005] The needle removal device according to the embodiments of this application has at least the following beneficial effects: by setting a workbench to divide the work area into a first station, a second station, and a working area, the needle removal operation can be carried out in an orderly manner. The first and second stations are used for loading and unloading fixtures, while the working area is used for needle fitting and removal operations. The coordinated arrangement of the first carrier plate, the second carrier plate, the connecting plate, and the drive assembly allows the drive assembly to horizontally drive the connecting plate, moving the first and second carrier plates towards the first station. When the first carrier plate reaches the first station, the second carrier plate will be positioned in the working area, allowing for loading and unloading of fixtures from the first carrier plate at the first station. In the working area, the needle loading and unloading assembly can be used to perform needle removal or needle fitting operations on the second carrier plate. After the second carrier plate completes the needle removal or fitting operation, the drive assembly horizontally drives the connecting plate to move the first and second carrier plates towards the second station. When the second carrier plate moves to the second station, the first carrier plate will be located in the working area. At this time, the fixture on the second carrier plate that has completed the needle removal or fitting operation can be loaded and unloaded at the second station. Meanwhile, in the working area, the needle loading and unloading assembly can be used to perform needle removal or fitting operations on the first carrier plate. This achieves alternating needle removal and fitting operations at two stations without stopping the equipment, thus greatly improving the efficiency of needle removal and fitting.

[0022] Currently, most needle ejection devices on the market are semi-automatic, and typically only have one workstation for employees to perform needle ejection operations. Therefore, after each needle ejection or insertion operation at this workstation, the employee needs to pause the machine, remove the used needle tray, replace it with a new batch of trays for needle ejection or insertion, and then restart the machine. It can be seen that during the pause of the machine, the needle ejection operation also stops accordingly. Therefore, the efficiency of traditional needle ejection equipment in performing needle ejection operations is relatively low.

[0023] Based on this, this application proposes a needle ejection device and system that can realize alternating needle ejection at two stations, thereby improving the efficiency of needle ejection.

[0024] It is understood that the dual-tablet needle ejection device of this application includes a worktable 100, a drive assembly, a feeding assembly, and a needle loading and unloading assembly. The worktable 100 has a first station, a second station, and a working area. The first station and the second station are respectively located at opposite ends of the worktable 100, and the working area is located between the first station and the second station. The drive assembly is located on the worktable 100. The feeding assembly includes a first material carrier plate 120, a second material carrier plate 130, and a connecting plate 110. The first material carrier plate 120 is located at the end of the connecting plate 110 near the first station, and the second material carrier plate 130 is located at the end of the connecting plate 110 near the second station. The moving component is used to drive the connecting plate 110 in the horizontal direction to move the first material carrier plate 120 back and forth between the first station and the working area, and to move the second material carrier plate 130 back and forth between the second station and the working area. The first material carrier plate 120 and the second material carrier plate 130 are used to load the fixture. When the first material carrier plate 120 moves to the working area, the second material carrier plate 130 is located at the second station. When the second material carrier plate 130 moves to the working area, the first material carrier plate 120 is located at the first station. The needle loading and unloading component is located above the working area. The needle loading and unloading component is used to perform needle loading or unloading operations on the fixture.

[0025] The beneficial effects of the dual-tablet needle ejection device in this application embodiment are as follows: By dividing the worktable 100 into a first station, a second station, and a working area, the orderly operation of the needle ejection process is ensured. The first and second stations are used for loading and unloading fixtures, while the working area is used for needle insertion and ejection operations. The coordinated arrangement of the first carrier plate 120, the second carrier plate 130, the connecting plate 110, and the drive assembly allows the drive assembly to horizontally drive the connecting plate 110, moving the first and second carrier plates 120 and 130 towards the first station. When the first carrier plate 120 reaches the first station, the second carrier plate 130 will be positioned in the working area. At this point, the fixtures on the first carrier plate 120 can be loaded and unloaded at the first station. In the working area, the needle loading and unloading assembly can be used to perform needle removal or needle fitting operations on the second carrier plate 130. After the second carrier plate 130 completes the needle removal or needle fitting operation, the drive assembly horizontally drives the connecting plate 110 to move the first carrier plate 120 and the second carrier plate 130 towards the direction of the second station. When the second carrier plate 130 moves to the second station, the first carrier plate 120 will be located in the working area. At this time, the fixture on the second carrier plate 130, which has completed the needle removal or needle fitting operation, can be loaded and unloaded at the second station. In the working area, the needle loading and unloading assembly can be used to perform needle removal or needle fitting operations on the first carrier plate 120. This realizes the alternating needle removal and fitting operation between the two stations without stopping the equipment, which greatly improves the efficiency of needle removal and fitting.

[0026] For example, in some embodiments, reference is made to Figure 1In this embodiment, the workbench 100 is divided into a first station and a second station at both ends, with a working area between the first station and the second station. Both the first station and the second station are used for loading and unloading fixtures, while the working area is used for fitting or unloading needles from the fixtures. This division of areas facilitates a more orderly needle fitting and unloading process. A first material carrier plate 120 and a second material carrier plate 130 are provided on one side of the connecting plate 110. The first material carrier plate 120 is located at the end of the connecting plate 110 near the first station, and the second material carrier plate 130 is located at the end of the connecting plate 110 near the second station. The other side of the connecting plate 110 is connected to the drive assembly. This is to drive the connecting plate 110 to reciprocate between the first and second workstations, thereby driving the first carrier plate 120 to reciprocate between the first workstation and the working area, and driving the second carrier plate 130 to reciprocate between the second workstation and the working area. The specific operation process is as follows: In the first workstation area, a fixture requiring needle removal is assembled onto the first carrier plate 120. At this time, the first carrier plate 120 is located in the first workstation, and the second carrier plate 130 is located in the working area. The needle loading and unloading assembly then performs needle removal operations on the fixture located on the second carrier plate 130. When all fixtures on the second carrier plate 130 have completed removal... After the needle fitting operation, the drive assembly moves the connecting plate 110 towards the second station, thereby moving the second carrier plate 130 from the working area to the second station. Simultaneously, it moves the first carrier plate 120 from the first station to the working area. At this time, the needle loading and unloading assembly performs a needle unfitting operation on the fixture on the first carrier plate 120 in the working area. Meanwhile, the second carrier plate 130 at the second station simultaneously unloads the fixtures that have completed the needle unfitting operation and assembles a new batch of fixtures requiring needle unfitting. Once all fixtures on the first carrier plate 120 have completed the needle unfitting operation, the drive assembly again moves the connecting plate 110 towards the second station. The workstation moves in the direction of movement to move the first material carrier 120 from the work area back to the first workstation, and at the same time moves the second material carrier 130 from the second workstation to the work area. Thus, at the first workstation, the fixtures that have completed the needle unloading operation on the first material carrier 120 are unloaded, and a new batch of fixtures that need to be unloaded are then assembled. In the work area, the needle loading and unloading assembly performs the needle unloading operation on the second material carrier 130. This back-and-forth movement realizes the needle unloading operation on both workstations. Compared with traditional needle unloading equipment, the dual-workstation needle unloading device of this application does not require stopping the equipment and performs needle unloading operation at all times, thereby improving the efficiency of needle unloading.

[0027] It is understood that the drive assembly includes a cylinder and a drive unit. The cylinder includes a cylinder body 161, a piston, and a first connecting member 160. The cylinder body 161 is located on the side of the worktable 100 near the first material carrier plate 120. The cylinder body 161 extends in a direction parallel to the line connecting the first and second workstations. The piston is movably located inside the cylinder body 161. The drive unit is connected to both ends of the cylinder body 161. The drive unit is used to drive the piston to move along the cylinder body 161. The first connecting member 160 is movably sleeved on the outer side wall of the cylinder body 161. The side of the connecting plate 110 away from the first material carrier plate 120 is fixedly connected to the first connecting member 160. The piston is used to drive the first connecting member 160 to move along the outer side wall of the cylinder body 161 toward the line connecting the first and second workstations.

[0028] For example, in some embodiments, reference is made to Figure 2 In this embodiment, the piston is located inside the cylinder 161, and the first connecting member 160 is sleeved outside the cylinder 161. The piston and the first connecting member 160 are magnetically attracted to each other through the cylinder 161. Therefore, when the driving unit drives the piston to move along the cylinder 161, the piston will drive the first connecting member 160 to move along the outer wall of the cylinder 161, thereby driving the connecting plate 110 to move in the direction of the line connecting the first station and the second station, thereby realizing the alternating operation of the first material plate 120 and the second material plate 130 on the worktable 100.

[0029] It is understood that the double-sided table needle unloading device of this application also includes a first guide rail 102, with the two ends of the first guide rail 102 respectively located on both sides of the worktable 100. The first guide rail 102 extends along a direction perpendicular to the line connecting the first workstation and the second workstation. The needle loading and unloading assembly is located on the first guide rail 102 and can move along the first guide rail 102.

[0030] For example, in some embodiments, reference is made to Figure 1 In this embodiment, the first guide rail 102 is disposed above the worktable 100. The two ends of the first guide rail 102 are bent and extended and fixed to the opposite sides of the worktable 100. The first guide rail 102 extends in a direction perpendicular to the line connecting the first station and the second station. Therefore, the needle loading and unloading assembly can move back and forth along the first guide rail 102 in a direction perpendicular to the line connecting the first station and the second station, so that the needle loading and unloading assembly can more flexibly perform needle unloading operations on the fixtures on the first material plate 120 or the second material plate 130 in the working area.

[0031] It is understood that the double-sided table needle ejection device of this application also includes two second guide rails 101. The two second guide rails 101 are respectively located on both sides of the worktable 100. The two ends of the first guide rail 102 are respectively connected to the worktable 100 through the second guide rails 101. The second guide rails 101 extend in a direction parallel to the line connecting the first station and the second station. The first guide rail 102 can move along the second guide rails 101.

[0032] For example, in some embodiments, reference is made to Figure 1 In this embodiment, the second guide rail 101 extends parallel to the line connecting the first and second workstations. The two ends of the first guide rail 102 are movably connected to the two second guide rails 101, allowing the first guide rail 102 to move along the second guide rails 101. This, in turn, drives the needle loading and unloading assembly to reciprocate in a direction parallel to the line connecting the first and second workstations. The cooperation of the first guide rail 102 and the second guide rail 101 allows the needle loading and unloading assembly to reciprocate in a direction parallel or perpendicular to the line connecting the first and second workstations, improving the flexibility of the needle loading and unloading assembly and facilitating needle unloading operations in the work area, thereby further improving the efficiency of needle unloading. It is understandable that the first carrier plate 120 and the second carrier plate 130 are both provided with a first limiting hole 121, and the fixture is provided with a protrusion, with the first limiting hole 121 corresponding to the protrusion.

[0033] For example, in some embodiments, reference is made to Figure 1 In this embodiment, the first carrier plate 120 and the second carrier plate 130 are provided with a first limiting hole 121, and the fixture is provided with a protrusion that matches the first limiting hole 121, so that the fixture can be more securely installed on the first carrier plate 120 or the second carrier plate 130, preventing the fixture from detaching from the first carrier plate 120 or the second carrier plate 130, thereby affecting the efficiency of the ejection pin. At the same time, the protrusion also plays a certain guiding role. That is, the cooperation between the protrusion and the first limiting hole 121 makes it easier to install the fixture on the first carrier plate 120 or the second carrier plate 130 during feeding, thereby improving the feeding rate.

[0034] It is understandable that the first guide rail 102 is also equipped with a detection component 150. The detection component 150 is located on the same side as the needle loading and unloading component. The detection component 150 is used to detect the diameter of the needle to be loaded on the needle loading and unloading component when performing needle loading and unloading operation.

[0035] For example, in some embodiments, reference is made to Figure 1 In this embodiment, the detection component 150 is located on the side of the first guide rail 102 where the needle loading and unloading component is located. When the needle loading and unloading component performs needle removal or needle fitting operations, the detection component 150 will detect the diameter of the needle to be fitted or removed on the needle loading and unloading component to prevent needles of different diameters from being mixed in and affecting the processing of subsequent products.

[0036] It is understandable that the first carrier plate 120 and the second carrier plate 130 are also provided with second limiting holes, and the fixture is provided with locking parts, which are engaged with the second limiting holes.

[0037] For example, in some embodiments, the locking element (not shown in the figures) is a press-type quick-locker to enable quick installation and removal of the fixture, while also securing the connection between the fixture and the first carrier plate 120 or the second carrier plate 130.

[0038] It is understood that the needle loading and unloading assembly includes a needle loading and unloading unit 140, a third guide rail 141, and a second connector. The third guide rail 141 is connected to the first guide rail 102 through the second connector. The third guide rail 141 extends in a direction parallel to the extension direction of the first guide rail 102. The needle loading and unloading unit 140 is located on the side of the third guide rail 141 away from the second connector. The needle loading and unloading unit 140 can move along the third guide rail 141.

[0039] For example, in some embodiments, reference is made to Figure 1 In this embodiment, multiple needle loading and unloading units 140 are provided. The second connector can move along the first guide rail 102. The extension direction of the third guide rail 141 is parallel to the extension direction of the first guide rail 102. Multiple needle loading and unloading units 140 are movably connected to the third guide rail 141, so that multiple needle loading and unloading units 140 can move independently along the third guide rail 141 in a direction parallel to the extension direction of the first guide rail 102. This allows the needle loading and unloading units 140 to be more accurately positioned at the fixture where needles need to be withdrawn or fitted, thereby improving the accuracy and efficiency of needle withdrawal and fitting operations.

[0040] It is understandable that the cylinder is a rodless cylinder.

[0041] For example, in some embodiments, reference is made to Figure 2 In this embodiment, the cylinder is a rodless cylinder, which requires less space than a traditional rod cylinder, saving space costs. Moreover, compared with a rod cylinder, the rodless cylinder can more accurately position the connecting plate 110 to slide, further ensuring the accuracy of the needle removal operation.

[0042] It is understandable that: the workbench 100 is provided with a fourth guide rail 103 on both sides parallel to the line connecting the first station and the second station. The first material carrier 120 can move back and forth between the first station and the work area along the fourth guide rail 103, and the second material carrier 130 can move back and forth between the second station and the work area along the fourth guide rail 103.

[0043] For example, in some embodiments, reference is made to Figure 1 and Figure 2In this embodiment, the two sides of the first material carrier plate 120 are movably connected to the fourth guide rails 103 distributed on both sides of the worktable 100. This allows the first material carrier plate 120 to move along the fourth guide rails 103 when the drive assembly drives the connecting plate 110 to move back and forth between the first station and the worktable 100. This makes the reciprocating motion of the first material carrier plate 120 smoother and more efficient, thereby reducing the energy consumption required for the drive assembly to drive the connecting plate 110 to move the first material carrier plate 120 back and forth to a certain extent. Yes; similarly, the two sides of the second material carrier plate 130 are movably connected to the fourth guide rails 103 distributed on both sides of the worktable 100, so that when the drive assembly drives the connecting plate 110 to drive the second material carrier plate 130 to move back and forth between the second station and the worktable 100, the second material carrier plate 130 can move along the fourth guide rail 103, making the back and forth movement of the second material carrier plate 130 smoother and more efficient, and thus reducing the energy consumption required for the drive assembly to drive the connecting plate 110 to drive the second material carrier plate 130 to move back and forth to a certain extent.

[0044] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
