Description

Technical Field

[0001] This invention relates to the field of production equipment technology, and in particular to a folding and retracting device. Background Technology

[0002] A blood glucose meter is an electronic instrument that monitors blood glucose levels. Before monitoring, a needle must first be inserted into a blood vessel; therefore, the needle is an essential component of a blood glucose meter. In the manufacturing process of blood glucose meters, the needles are typically supplied in a row. Steel needles and plastic needle holders are connected by injection molding, and multiple plastic needle holders are connected by a strip, thus forming a row of needles. During assembly, the strip is first folded down to separate the multiple needles, and then each needle is individually assembled with the pulse oximeter body.

[0003] If the aforementioned material strip is broken manually, the breakage consistency is poor, and the breakage position is inconsistent with each operation, which affects the assembly and monitoring accuracy of the blood glucose meter. Moreover, manual breaking is inefficient and labor-intensive, thus increasing product costs. Some existing breaking devices are prone to breaking at the critical point where the gripper holds the product, and the breakage position is difficult to control, which in turn affects the accuracy of the breakage position. Summary of the Invention

[0004] The purpose of this invention is to provide a folding device that can accurately fold the connecting strip at a preset break line, ensuring good folding consistency, avoiding positional errors caused by manual operation, improving folding efficiency, reducing labor costs, and thus lowering product costs.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A breaking and separating device is provided for breaking and separating a workpiece module, the workpiece module comprising interconnected connecting strips and a plurality of workpieces spaced apart along the length direction of the connecting strips, wherein the connection between the connecting strips and the workpieces has a preset break line, and the breaking and separating device includes:

[0007] A feeding device, comprising a movable feeding component, which is capable of carrying the workpiece module and reciprocating it to the breaking station;

[0008] A breaking device, comprising a breaking component capable of clamping the connecting strip and reciprocating around a preset breaking line, so as to detach the connecting strip from the plurality of workpieces.

[0009] As a preferred structure of the present invention, the breaking assembly includes a hollow rotating platform and a gripper mechanism. The rotating shaft of the hollow rotating platform is coaxially arranged with the preset breaking line. The gripper mechanism is used to grip the connecting strip. The gripper mechanism is detachably connected to the hollow rotating platform. The hollow rotating platform is used to drive the gripper mechanism to reciprocate.

[0010] As a preferred structure of the present invention, the gripper mechanism includes two first clamping members that can move closer to or further away from each other. Each first clamping member has a clamping surface, and the two clamping surfaces are respectively disposed on both sides of the connecting strip. There is a buffer gap between the clamping surfaces and the connecting strip. When the gripper mechanism rotates, the connecting strip abuts against at least one of the clamping surfaces.

[0011] As a preferred structure of the present invention, the breaking assembly further includes a fixing hook, which is connected to the gripper mechanism and extends to the lower side of the gripper mechanism. When the gripper mechanism clamps the connecting strip, the end of the connecting strip away from the gripper mechanism is located in the hooking groove of the fixing hook.

[0012] As a preferred structure of the present invention, at least two fixed hooks are provided, and the two fixed hooks are spaced apart at both ends of the gripper mechanism along the length direction of the connecting strip, and the fixed hooks are located between two adjacent workpieces.

[0013] As a preferred embodiment of the present invention, the feeding device further includes a guide rail assembly, the feeding assembly being slidably connected to the guide rail assembly, the guide rail assembly including a feeding station, a breaking station and a discharging station arranged sequentially at intervals.

[0014] As a preferred structure of the present invention, the feeding assembly includes an elastic mechanism and two opposing second clamping members. The second clamping members are connected to the elastic mechanism, and the elastic mechanism always has a tendency to push the second clamping members toward the workpiece, so that the two second clamping members can simultaneously elastically clamp multiple workpieces.

[0015] As a preferred embodiment of the present invention, the feeding device further includes an unlocking component, which is disposed at the feeding station and / or the unloading station. When the feeding component slides along the guide rail assembly to the feeding station or the unloading station, the unlocking component enables the two second clamping members to move away from each other.

[0016] In a preferred embodiment of the present invention, the unlocking component includes an unlocking block having two guide ramps arranged at an angle, the apex of which faces two second clamping members. The two second clamping members are capable of sliding along their respective guide ramps to move away from each other; and / or,

[0017] The feeding assembly further includes at least two cams, which are respectively disposed on the two second clamping members. The cams are capable of rolling along the unlocking assembly to drive the two second clamping members away from each other.

[0018] As a preferred embodiment of the present invention, the folding device further includes a recycling device, wherein the recycling port of the recycling device is disposed on one side of the folding station.

[0019] The beneficial effects of this invention are:

[0020] The folding device provided by this invention has a folding component that can clamp the connecting strip and reciprocate around a preset folding line to detach the connecting strip from multiple workpieces. Because the folding component reciprocates around the preset folding line, it avoids breaking at critical positions during clamping, ensuring that each folding operation breaks around the preset folding line, improving the consistency and accuracy of the folding position. Furthermore, the reciprocating rotation of the folding component simulates the folding action of a human hand, avoiding workpiece damage caused by forcibly breaking the connecting strip. The folding process does not require manual operation, avoiding positional errors from manual operation, improving folding efficiency, reducing labor costs, and thus lowering product costs.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0039] like Figures 1-7 As shown, this embodiment of the invention provides a breaking and separating device for breaking and separating workpiece module 100. Figure 3 As shown, the workpiece module 100 includes interconnected connecting strips 101 and multiple workpieces 102 spaced apart along the length of the connecting strips 101. The connection points between the connecting strips 101 and the workpieces 102 have preset break lines 103. It should be noted that the preset break line 103 is not a solid line, but rather a preset weakest point. It can be formed in various ways, such as thinning the material at the preset break line 103, to increase the accuracy of the break position of the bending device. In this embodiment, the workpieces 102 are steel needles, with eight needles arranged in a row. In other embodiments, the workpieces 102 can be other structural components, and different numbers of workpieces 102 can be arranged in a row, not limited to this embodiment.

[0040] The bending device includes a feeding device 1 and a bending device 2. The feeding device 1 includes a movable feeding assembly 11, which can transfer the workpiece module 100 and reciprocate to the bending station 121. The bending device 2 includes a bending assembly 21, which can clamp the connecting strip 101 and reciprocate around a preset bending line 103 to detach the connecting strip 101 from multiple workpieces 102. Since the bending assembly 21 reciprocates around the preset bending line 103, it can avoid breaking at the critical position of the clamping point, ensuring that each bending operation breaks around the preset bending line 103, improving the consistency and accuracy of the bending position; moreover, the reciprocating rotation process of the bending assembly 21 simulates the bending action of a human hand, avoiding damage to the workpieces 102 caused by the hard breaking of the connecting strip 101. The bending process does not require manual operation, avoiding positional errors caused by manual operation, improving bending efficiency, reducing labor costs, and thus reducing product costs.

[0041] In one embodiment, the breaking assembly 21 includes a hollow rotating platform 211 and a gripper mechanism 212. The rotating shaft of the hollow rotating platform 211 is coaxially arranged with the preset breaking line 103. The gripper mechanism 212 is used to grip the connecting strip 101. The gripper mechanism 212 is detachably connected to the hollow rotating platform 211, and the hollow rotating platform 211 is used to drive the gripper mechanism 212 to reciprocate. The hollow rotating platform 211 is a rotating platform driven by a motor to automate angle adjustment. It has advantages such as high rigidity, high rotational accuracy, and high repeatability, thereby improving the action accuracy of the gripper mechanism 212. The coaxial arrangement of the rotating shaft of the hollow rotating platform 211 and the preset breaking line 103 ensures that the gripper mechanism 212 always reciprocates around the preset breaking line 103, further improving the consistency and accuracy of the breaking position.

[0042] In one embodiment, such as Figure 4 and Figure 5As shown, the gripper mechanism 212 includes two first gripping members 2121. The two first gripping members 2121 can move closer to each other or further away from each other. The actions of the two first gripping members 2121 can be synchronous or asynchronous. In this embodiment, the gripper mechanism 212 controls the synchronous action of the two first gripping members 2121 through a cylinder. The first gripping member 2121 has a gripping surface 21211. The two gripping surfaces 21211 are respectively disposed on both sides of the connecting material strip 101. There is a buffer gap between the gripping surface 21211 and the connecting material strip 101. When the gripper mechanism 212 rotates, the connecting material strip 101 at least abuts against one side of the gripping surface 21211. That is, when the gripper mechanism 212 rotates and breaks, the connecting material strip 101 will never detach from the gripper mechanism 212. Moreover, the gripping surface 21211 can provide a force to the connecting material strip 101, so that the connecting material strip 101 can rotate around the preset break line 103 and then break. In the above process, the buffer gap provides cushioning, preventing the gripper mechanism 212 from forcibly pulling the connecting strip 101, thus avoiding shearing force on the connecting strip 101. It is understood that since the connecting strip 101 has a certain thickness, if the gripper mechanism 212 clamps both sides of the connecting strip 101, it will pull the connecting strip 101 during rotation, subjecting it to shearing force. This shearing force will cause the connecting strip 101 to break at the clamping point rather than at the preset break line 103. Therefore, the existence of the buffer gap allows the connecting strip 101 a certain degree of positional freedom. During reciprocating rotation, the connecting strip 101 can dynamically oscillate, adjusting its relative position with the gripper mechanism 212. This ensures that the connecting strip 101 is always under force and can rotate and break around the preset break line 103, while preventing the connecting strip 101 from being forcibly pulled.

[0043] Optionally, the movement of the two first clamping members 2121 can be achieved by various driving structures. In this embodiment, the two first clamping members 2121 are brought closer to each other or moved away from each other by a cylinder.

[0044] In one embodiment, the breaking assembly 21 further includes a fixing hook 213, such as Figure 4 and Figure 5 As shown, the fixed hook 213 is connected to the gripper mechanism 212 and extends to the lower side of the gripper mechanism 212. When the gripper mechanism 212 clamps the connecting strip 101, the end of the connecting strip 101 away from the gripper mechanism 212 is located in the hook groove 2131 of the fixed hook 213. Because there is a buffer gap between the clamping surface 21211 and the connecting strip 101, the fixed hook 213 can prevent the connecting strip 101 from falling off the gripper mechanism 212.

[0045] Furthermore, at least two fixed hooks 213 are provided, with the two fixed hooks 213 spaced apart at both ends of the gripper mechanism 212 along the length direction of the connecting material strip 101, and the fixed hooks 213 located between two adjacent workpieces 102. Since the workpiece module 100 includes multiple workpieces 102 spaced apart along the length direction of the connecting material strip 101 and has a certain length, the fixed hooks 213 at both ends of the gripper mechanism 212 make the lifting of the connecting material strip 101 more reliable.

[0046] In one embodiment, the feeding device 1 further includes a guide rail assembly 12, such as... Figure 6 As shown, the feeding assembly 11 is slidably connected to the guide rail assembly 12. The guide rail assembly 12 includes a feeding station 122, a breaking station 121, and a discharging station 123 arranged sequentially at intervals. In this embodiment, the guide rail assembly 12 adopts a linear module. The linear module has more accurate positioning and higher repeatability, which can accurately control the positional accuracy of the feeding assembly 11 and ensure that the gripper mechanism 212 can accurately clamp the connecting strip 101. In other embodiments, a structure can also be used where a motor drives a lead screw to rotate, thereby moving the guide rail assembly 12 on the lead screw. This embodiment will not be described in detail here.

[0047] When the guide rail assembly 12 moves to the loading station 122, the picking device 4 of the folding device can sequentially remove the workpiece module 100 from the hopper 41 and place it on the loading assembly 11. The loading assembly 11 carries the workpiece module 100 to the breaking station 121, where the breaking device 2 breaks and removes the connecting strip 101 of the workpiece module 100. Finally, the loading assembly 11 carries multiple workpieces 102 to the unloading station 123, where the unloading device 5 removes the multiple workpieces 102 sequentially for subsequent assembly. The structure and operation of the picking device 4 and the unloading device 5 are not the focus of this embodiment and will not be described in detail here.

[0048] It should be noted that, in this embodiment, the breaking component 21 further includes moving modules in the X and Z directions, such as... Figure 4 The coordinate system shown is as follows: the gripper mechanism 212 can move horizontally above the breaking station 121 via the X-direction moving module, and the gripper mechanism 212 can move vertically towards the feeding assembly 11 via the Z-direction moving module until it can clamp the connecting strip 101. The X-direction and Z-direction moving modules are existing technologies in the art, and will not be described in detail here.

[0049] In one embodiment, such as Figure 7As shown, the loading assembly 11 includes an elastic mechanism 111 and two opposing second clamping members 112. The second clamping members 112 are connected to the elastic mechanism 111. The elastic mechanism 111 always has a tendency to push the second clamping members 112 towards the workpiece 102, so that the two second clamping members 112 can simultaneously elastically clamp multiple workpieces 102. In this embodiment, the elastic mechanism 111 is a compression spring, which can drive the two second clamping members 112 to move closer to each other, thereby clamping multiple workpieces 102 between the two second clamping members 112. This elastic clamping structure of the loading assembly 11 can avoid excessive clamping force from damaging the workpieces 102 and improve clamping reliability.

[0050] In one embodiment, the loading device 1 further includes an unlocking component 13, which is disposed at the loading station 122 and / or the unloading station 123. When the loading component 11 slides along the guide rail component 12 to the loading station 122 or the unloading station 123, the unlocking component 13 can make the two second clamping members 112 move away from each other, so that the picking device 4 can place the workpiece module 100 between the two second clamping members 112, or the unloading device 5 can remove multiple workpieces 102 in sequence.

[0051] Specifically, the unlocking component 13 includes an unlocking block 131, which has two guide ramps 1311. The two guide ramps 1311 are set at an angle, with the apex of the angle facing the two second clamping members 112. The two second clamping members 112 can slide along the corresponding guide ramps 1311 to move away from each other. And / or, the feeding component 11 also includes at least two cams 113, which are respectively set on the two second clamping members 112. The cams 113 can roll along the unlocking component 13 to drive the two second clamping members 112 away from each other.

[0052] In this embodiment, the unlocking component 13 includes an unlocking block 131, and each end of the two second clamping members 112 is provided with a cam 113. One cam 113 assists in unlocking at the loading station 122, and the other cam 113 assists in unlocking at the unloading station 123. As the loading component 11 gradually approaches the unlocking block 131, the cam 113 rolls along the guide slope 1311, allowing the second clamping members 112 to overcome the elastic force of the elastic mechanism 111, and the two second clamping members 112 gradually move away from each other. Correspondingly, as the loading component 11 gradually moves away from the unlocking component 13, under the elastic force of the elastic mechanism 111, the two second clamping members 112 gradually move closer to each other, thereby clamping the workpiece module 100. Through this unlocking structure, the two second clamping members 112 gradually move away or gradually move closer, avoiding sudden clamping of the workpiece module 100 or sudden drop of the workpiece module 100, making the clamping of the workpiece module 100 more reliable.

[0053] In one embodiment, the folding device further includes a worktable 10 and a recycling device 3, such as Figure 2 As shown, the recycling port 31 of the recycling device 3 is located on the workbench 10 and is situated on one side of the breaking station 121. After the breaking device 2 breaks the connecting strip 101, the gripper mechanism 212 moves the connecting strip 101 to the recycling device 3 and places it into the recycling port 31. During the movement, the fixing hook 213 prevents the connecting strip 101 from falling off.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
