Description

Technical Field

[0001] This application relates to the field of hardware tools technology, and in particular to a jig and marking equipment for mass assembly of workpieces. Background Technology

[0002] After the screwdriver is manufactured, it is usually necessary to mark the handle of the screwdriver to distinguish the screwdriver's specifications and batch.

[0003] Currently, the traditional method of marking screwdrivers generally uses pad printing. Specifically, the screwdriver is placed in a pad printing fixture to fix it, and then the pad printing head presses down on the handle of the screwdriver to mark it. However, the pad printing fixture can only hold 1-2 screwdrivers at a time for pad printing and marking. Moreover, before marking, the staff needs to manually place the screwdrivers one by one in the pad printing fixture, resulting in low marking efficiency and limitations for mass production. Utility Model Content

[0004] Therefore, it is necessary to address the problem of low marking efficiency when using existing technology for batch marking of screwdrivers, and to provide a fixture for batch installation of workpieces and a marking device including the fixture, in order to solve the above problems.

[0005] According to one aspect of this application, a fixture for batch mounting of workpieces is provided, comprising:

[0006] Driver source;

[0007] A turntable is connected to the output shaft of the drive source, and the turntable can rotate around its own central axis under the drive of the drive source;

[0008] Multiple suspension components are spaced apart along the circumference of the turntable. Each suspension component has a mounting end and a suspension end that are arranged opposite to each other. The mounting end is detachably connected to the turntable, and the suspension end is used to suspend the workpiece.

[0009] Multiple positioning components are provided, each corresponding to one of the multiple suspension components. Each positioning component is connected to a corresponding suspension component, and each positioning component has a positioning groove that extends through the positioning component along the axial direction of the turntable. The positioning groove is used for the workpiece to pass through and position the workpiece.

[0010] In one embodiment, each of the suspension members has an extension rod extending radially along the turntable at its suspension end. The extension rod is suspended relative to the turntable for passing through the workpiece, such that the workpiece can be suspended on the extension rod.

[0011] In one embodiment, a plurality of limiting grooves are provided on the upper side of the turntable near the edge of the turntable, and the mounting end of each suspension member is detachably installed in a corresponding limiting groove.

[0012] In one embodiment, the edge of the turntable is provided with a plurality of clearance grooves spaced apart along the circumference of the turntable, and at least a portion of the suspension end of each suspension member is located in a corresponding clearance groove.

[0013] In one embodiment, the fixture further includes a positioning member connected to the suspension member, the positioning member having a positioning groove extending through the positioning member along the axial direction of the turntable, the positioning groove being used for the workpiece to pass through and position the workpiece.

[0014] In one embodiment, the positioning member includes a fixing part and a positioning part that are perpendicularly connected to each other. The fixing part is connected to the suspension end of the suspension member, and the positioning part extends radially away from the central axis of the turntable. The positioning groove is formed on the positioning part.

[0015] In one embodiment, the positioning groove is open at one end away from the fixing part, so that the positioning groove is an open structure.

[0016] In one embodiment, the opening size of the positioning groove gradually decreases in a direction along the radial direction of the turntable and close to the central axis of the turntable, so that the positioning groove is V-shaped.

[0017] In one embodiment, the suspension element is detachably connected to the turntable by fasteners.

[0018] In one embodiment, the drive source is configured to drive the turntable to rotate intermittently and periodically.

[0019] According to another aspect of this application, a marking device is provided, comprising:

[0020] The fixture as described in any of the above embodiments has a marking station on one side;

[0021] A first marking head and / or a second marking head, wherein the first marking head is located above the marking station and the second marking head is located beside the marking station; when the turntable of the fixture rotates, each of the suspended components can pass through the marking station in sequence, so that the first marking head and / or the second marking head can mark the workpieces suspended on the suspended components in sequence.

[0022] The aforementioned fixture for batch mounting of workpieces and the marking equipment including the fixture, by setting a turntable connected to a drive source, arranges multiple suspension members spaced apart along the circumference of the turntable. The mounting end of each suspension member is detachably connected to the turntable, and the suspension end is used to suspend the workpiece. Each suspension member is connected to a positioning member, and each positioning member has a positioning groove that passes through the positioning member along the axial direction of the turntable. This allows multiple workpieces to be suspended on the fixture simultaneously, and each workpiece can be fixed by passing through the positioning groove. Driven by the drive source, the turntable can rotate around its central axis, causing each suspension member to pass through the marking station sequentially without wobbling. This allows the workpieces suspended on each suspension member to be marked sequentially as they pass through the marking station, enabling batch marking of multiple workpieces in a short time. Therefore, it saves labor intensity and significantly improves marking efficiency. Attached Figure Description

[0035] One embodiment of this application provides a fixture for batch mounting of workpieces and a marking device including the fixture. The marking device is used to mark the workpieces so as to distinguish the model or production batch of the workpieces. The fixture is used to batch mount multiple workpieces so as to enable batch marking of multiple workpieces in a short time.

[0036] The following description uses a screwdriver as an example to illustrate the structure of the fixture and marking equipment in this application. The embodiments of this application are only used as examples and do not limit the technical scope of this application. It is understood that in other embodiments, the fixture provided in this application is not limited to batch mounting of screwdrivers, but can also batch mount any workpiece to enable batch marking of the workpieces, and no limitation is made here.

[0037] See Figure 1 , Figure 1 A schematic diagram of a marking device 10 according to an embodiment of this application is shown. The marking device 10 provided in one embodiment of this application includes a fixture 100, a first marking head 200, and a second marking head 300. The fixture 100 has a marking station 11 on one side. The first marking head 200 is positioned above the marking station 11 and can move vertically (Z direction as shown in the figure) to mark the bottom surface of the screwdriver handle 50. The second marking head 300 is positioned beside the marking station 11 and can move horizontally (X direction as shown in the figure) to mark the side of the screwdriver handle 50. The fixture 100 is used to batch install multiple screwdrivers 50, so that the first marking head 200 and the second marking head 300 can conveniently and sequentially mark multiple screwdrivers 50 in a short time.

[0038] exist Figure 1In the illustrated embodiment, the fixture 100 includes a drive source 110, a turntable 120, and multiple positioning components 130. The turntable 120 is disc-shaped. The drive source 110 is positioned below the turntable 120 and is driveably connected to the output shaft of the drive source 110. The multiple positioning components 130 are spaced apart on the turntable 120 around its circumference, forming a circumferential array on the turntable 120. Each positioning component 130 is used to mount a screwdriver 50, allowing multiple screwdrivers 50 to be mounted on the fixture 100. Driven by the drive source 110, the turntable 120 can rotate around its central axis, allowing each positioning component 130 to sequentially pass through the marking station 11, enabling the first marking head 200 and the second marking head 300 to sequentially mark the multiple screwdrivers 50 mounted on the fixture 100.

[0039] In a preferred embodiment, the drive source 110 is a stepper motor configured to drive the turntable 120 to rotate intermittently and periodically, so that each positioning component 130 can temporarily stop when passing the marking station 11. This allows the screwdriver 50 to be easily marked by the first marking head 200 and the second marking head 300 while it is stationary, thereby avoiding misalignment during marking when the screwdriver 50 is not stationary. Figure 1 In the example of the embodiment, there are twelve positioning components 130 in total. Therefore, whenever the turntable 120 rotates 30° around its own central axis, a screwdriver 50 can be marked. Of course, the number of positioning components 130 is not limited and can be any number.

[0040] More specifically, in some embodiments, such as Figure 2 As shown, each positioning component 130 includes a suspension member 131 and a positioning member 132 connected to each other. The suspension member 131 is connected to the turntable 120 and has a mounting end 131a and a hanging end 131b arranged opposite to each other. The mounting end 131a is detachably connected to the turntable 120, and the hanging end 131b is used to hang the screwdriver 50. The positioning member 132 is connected to the hanging end 131b of the suspension member 131 and is used to position and fix the screwdriver 50 to prevent the screwdriver 50 from shaking randomly when it moves with the positioning component 130 and when it is being marked.

[0041] In a preferred embodiment, the suspension member 131 is detachably mounted on the upper side of the turntable 120 near its edge, allowing the positioning component 130 to be easily detached from and replaced. This enables the positioning component 130 to be replaced with a positioning component 130 that can suspend, but is not limited to, the screwdriver 50, thereby making the fixture 100 provided in this application more versatile. As an example, the suspension member 131 is detachably mounted on the turntable 120 using fasteners 400 such as bolts or screws. Of course, the method of detachably mounting the suspension member 131 on the turntable 120 is not limited to this; it can also be magnetically attached or adhesively bonded, etc., and is not limited here.

[0042] Furthermore, to facilitate the suspension of the screwdriver 50, each suspension member 131 has a suspension end 131b with an extension rod 131c extending radially along the turntable 120. The extension rod 131c is suspended relative to the turntable 120 for passing through a tail hole opened in the handle of the screwdriver 50, so that the screwdriver 50 can be suspended on the extension rod 131c.

[0043] See Figure 3 , Figure 3 A schematic diagram of the structure at the connection position between the turntable 120 and the suspension member 131 is shown. In the embodiment shown in the figure, a limiting groove 121 is formed on the upper side of the turntable 120 near the edge of the turntable 120. There are multiple limiting grooves 121, and all limiting grooves 121 correspond one-to-one with all suspension members 131. Therefore, all limiting grooves 121 are also spaced apart along the circumferential direction of the turntable 120. The mounting end 131a of each suspension member 131 is detachably installed in a corresponding limiting groove 121.

[0044] Thus, by opening a limiting groove 121 on the turntable 120, the suspension component 131 can be limited in the limiting groove 121 after being installed on the turntable 120. Even if the fastener 400 is not tightened properly, the suspension component 131 can be prevented from rotating relative to the turntable 120, thereby preventing the screwdriver 50 from rotating with the suspension component 131 relative to the turntable 120 and affecting the marking quality.

[0045] Optionally, the edge of the turntable 120 is also provided with a plurality of clearance grooves 122 spaced apart along the circumference of the turntable 120. The number of clearance grooves 122 is also consistent with the number of suspension members 131. The clearance grooves 122 can avoid interference with the extension rods 131c, so that the extension rods 131c of each suspension member 131 are at least partially located in a corresponding clearance groove 122, thereby reducing the overall size of the fixture 100 in the radial direction of the turntable 120 and saving the space occupied by the fixture 100.

[0046] Regarding the structure of positioning element 132, such as Figure 2 and Figure 3As shown, the positioning member 132 has a positioning groove 132a that extends through the positioning member 132 along the axial direction of the turntable 120. The positioning groove 132a is used for the screwdriver 50 to pass through, so as to position the screwdriver 50 and prevent the screwdriver 50 from shaking when being marked or when the turntable 120 rotates, thereby preventing the marking from being off-center. Specifically, the positioning member 132 includes a fixing part 1321 and a positioning part 1322 that are perpendicularly connected to each other. The fixing part 1321 is connected to the suspension end 131b of the suspension member 131, and the positioning part 1322 extends radially away from the central axis of the turntable 120. Optionally, the positioning groove 132a is formed on the positioning part 1322, and the positioning groove 132a is open at the end away from the fixing part 1321, so that the positioning groove 132a is an open structure. When screwdriver 50 needs to be installed onto positioning assembly 130, simply insert the extension rod 131c of the hanger into the tail hole in the handle of screwdriver 50, and then push screwdriver 50 towards the center of fixture 100. This allows the screwdriver shank of screwdriver 50 to enter the positioning groove 132a through the opening. The groove wall of positioning groove 132a abuts against the screwdriver shank of screwdriver 50, thus positioning screwdriver 50 and preventing it from shaking. In a preferred embodiment, such as... Figure 4 As shown, the positioning groove 132a is V-shaped, that is, in the direction along the radial direction of the turntable 120 and close to the central axis of the turntable 120, the groove size of the positioning groove 132a (i.e., Figure 4 Dimension B in the middle gradually decreases. Thus, as... Figure 4 As shown, the positioning groove 132a can be adapted to tool holders of different thicknesses. Regardless of whether the tool holder is thicker or thinner, it can abut against the groove wall of the positioning groove 132a, thereby making the positioning assembly 130 more versatile.

[0047] Therefore, the fixture 100 provided in this application achieves batch positioning of screwdrivers 50 by using a circumferentially arrayed positioning component 130. Moreover, the positioning component 130 can be easily disassembled and replaced from the turntable 120, thus giving the fixture 100 good versatility. Furthermore, the positioning groove 132a opened in the positioning component 132 of the positioning component 130 has a V-shaped open structure, which can be adapted to screwdriver 50 tool holders of different thicknesses, solving the problem that batch positioning and marking of screwdrivers 50 cannot be performed in a short time during the marking process, thereby saving labor intensity and greatly improving marking efficiency.

[0048] Finally, it should be noted that the marking device 10 provided in this application can also selectively be configured with only one of the first marking head 200 and the second marking head 300. The specific configuration can be made according to the needs and is not limited here.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
