Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, and in particular to a screw-driving machine. Background Technology

[0002] In the current field of automated assembly, the use of automatic screw-driving equipment for fastening low-torque screws has become a common process. This type of operation typically requires relatively low holding force on the workpiece, and the equipment structure is relatively simple, meeting routine assembly needs. However, when dealing with workpieces that require a higher pre-tightening holding force before screw fastening to prevent displacement or ensure the pre-tightening effect, existing equipment cannot provide or stably maintain the required high holding force. During the initial stages of releasing the workpiece pre-tightening or screwing it in, the workpiece is highly prone to misalignment. This misalignment not only prevents the screw from being smoothly inserted into the threaded hole, causing machining defects such as stripping and misalignment, but more seriously, it necessitates frequent interruptions of the automated process for manual correction and realignment, significantly reducing overall processing efficiency and the first-pass yield of products.

Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of those features. In the description of this utility model, unless otherwise stated, "several" means two or more.

[0020] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0021] The following is as follows Figures 1 to 11 A screwdriver according to an embodiment of the present invention is described.

[0022] like Figure 1 As shown, the screw-driving machine according to an embodiment of the present invention includes a moving mechanism 100, a clamping mechanism 200, a pin-pulling mechanism 300, a locking mechanism 500, and a feeding mechanism 600. The clamping mechanism 200 includes a cover pressure member 210 and a lifting module 220 arranged vertically. The cover pressure member 210 has a plurality of first through holes 211. The lifting end of the lifting module 220 is adapted to place the workpiece, and the lifting end of the lifting module 220 is adapted to move upward to cooperate with the cover pressure member 210 to clamp the workpiece. The first through holes 211 are adapted to accommodate the preload on the workpiece. The pin-pulling mechanism 300 is located at the transmission end of the moving mechanism 100. The moving mechanism 100 is adapted to drive the pin-pulling mechanism 300 to move above the first through hole 211. The pin-pulling mechanism 300 is adapted to pull out the pre-tightened part. The locking mechanism 500 is located at the transmission end of the moving mechanism 100. The output end of the feeding mechanism 600 is adapted to feed the fastener. The moving mechanism 100 is adapted to drive the locking mechanism 500 to move between the feeding mechanism 600 and the first through hole 211. The locking mechanism 500 is adapted to drive the fastener to pass through the first through hole 211 to process the workpiece.

[0023] When the device is running, the workpiece is placed on the lifting module 220, which lifts the workpiece upward and cooperates with the cover clamp 210 to hold the workpiece. During the upward movement, the pre-tightening pin on the workpiece passes through the cover clamp 210 through the first through hole 211. The moving mechanism 100 drives the pin-pulling mechanism 300 to move above the workpiece and pull out the pre-tightening pin. After the pre-tightening pin is pulled out, the workpiece remains stable under the clamping of the lifting module 220 and the cover clamp 210. The moving mechanism 100 drives the locking mechanism 500 to obtain the fastener screw (not shown in the figure) from the feeding mechanism 600 and moves the fastener screw to the original position where the pre-tightening pin was pulled out. The fastener screw is then locked onto the workpiece through the first through hole 211. Then the lifting module 220 moves down to release the clamping of the workpiece. Under the action of the fastener screw, the workpiece's own structure will not shift. The workpiece is then removed, thus completing the processing.

[0024] It is understandable that, for a workpiece of the same type, since the processing position is the same, the movement trajectory of the moving mechanism 100 can be set in advance using a control system (not shown in the figure), so that the moving mechanism 100 can drive the pin pulling mechanism 300 and the locking mechanism 500 to move to the processing position, and can also drive the locking mechanism 500 to obtain fasteners from the feeding mechanism 600.

[0025] It is understandable that the locking mechanism 500 can be a common electric locking tool such as a screwdriver or electric bolt screwdriver, and can be selected accordingly to match fasteners.

[0026] It is understandable that preloaded parts can also be common connecting parts such as screws and bolts, and fasteners can also be common parts such as bolts and pins, and the selection can be adapted according to the needs of the workpiece.

[0027] It is understandable that, given the different positions of the pre-tightening components for different types of workpieces, the appropriate cover pressure component 210 can be replaced to improve the applicability of the device.

[0028] It is understandable that, such as Figure 2 As shown, when the pre-tightening component is a pin, the pin-pulling mechanism 300 includes a first cylinder drive module 310, and a second cylinder drive module 320 is provided at the drive end of the first cylinder drive module 310. The second cylinder drive module 320 is provided with a first clamping part 321 and a second clamping part 322. The first clamping part 321 and the second clamping part 322 can move relative to each other left and right, thereby clamping and fixing the pin in the horizontal direction.

[0029] It is understandable that, such as Figure 3As shown, the screw-driving machine also includes a housing 800, which can cover the moving mechanism 100, clamping mechanism 200, pin-pulling mechanism 300, pre-tightening component output mechanism 400, locking mechanism 500 and feeding mechanism 600, providing a certain degree of protection. In addition, the housing 800 can provide a support structure (not shown in the figure), making the whole device more compact.

[0030] In some specific embodiments of this utility model, a visual positioning mechanism 700 is also included. The visual positioning mechanism 700 and the pin-pulling mechanism 300 are arranged side by side from left to right on the transmission end of the moving mechanism 100.

[0031] like Figure 1 As shown, in this embodiment, the visual positioning mechanism 700 uses a CCD camera and is positioned between the locking mechanism 500 and the pin-pulling mechanism 300, so that the image acquired by the visual positioning mechanism 700 can be simultaneously applied to both the locking mechanism 500 and the pin-pulling mechanism 300. It is understood that this arrangement of the visual positioning mechanism 700 can improve the accuracy of processing. It is also understood that the visual positioning mechanism 700 can be equipped with multiple CCD cameras, each corresponding one-to-one with the locking mechanism 500 and the pin-pulling mechanism 300, resulting in even more precise alignment, but at a higher cost.

[0032] In some specific embodiments of this utility model, the lifting module 220 includes a lifting component 221, a fixing member 222, and a movable platform 223. The output end of the lifting component 221 passes through the fixing member 222 and is connected to the movable platform 223. The movable platform 223 is movably connected to the fixing member 222 through a transmission guide component 224. A product placement member 225 is provided on the upper surface of the movable platform 223. The product placement member 225 is suitable for placing workpieces and is located below the cover pressure member 210.

[0033] like Figure 1 and Figure 4 As shown, in this embodiment, the transmission end of the lifting assembly 221 is fixedly connected to the movable platform 223 via a fixing member 222, which can drive the movable platform 223 to move up and down relative to each other, thereby driving the product placement member 225 with the workpiece installed to move up and down. The movable platform 223 is located below the cover pressure member 210, and can drive the product placement member 225 with the workpiece installed to cooperate with the cover pressure member 210 to form a clamp, thereby ensuring that the workpiece can remain stable after the pre-tightening member on the workpiece is removed, providing processing conditions for the next processing and locking. The upper end of the transmission guide assembly 224 is fixedly connected to the movable platform 223, and the lower end of the transmission guide assembly 224 is fixedly connected to the fixing member 222 via a fixing member 222, which can assist the relatively stable up and down movement of the movable platform 223.

[0034] It is understandable that the movable platform 223 may also be equipped with elastic pads 2231 to provide a certain buffering capacity for the connection with the product placement component 225, preventing excessive clamping and damage to the workpiece when it is clamped with the cover clamping component 210. It is also understandable that the movable platform 223 may be equipped with positioning protrusions 2232 to stably connect to the product placement component 225 and achieve accurate positioning. Furthermore, it is understandable that the lifting assembly 221 may use a cylinder or motor to drive the telescopic element. In some specific embodiments of this utility model, the clamping mechanism 200 further includes a workpiece transmission assembly 230, which is located below the cover pressure member 210. The lifting module 220 passes through the workpiece transmission assembly 230, and the transmission end of the workpiece transmission assembly 230 is adapted to contact the product placement member 225. The workpiece transmission assembly 230 is adapted to drive the product placement member 225 to move below the cover pressure member 210.

[0035] like Figure 1 and Figure 5 As shown, in this embodiment, the workpiece transmission assembly 230 is a conveyor belt structure. It can move the product placement piece 225, on which the workpiece is mounted, from the left or right side to between the movable platform 223 and the cover member 210 via a motor-driven conveyor belt structure at both ends. This facilitates the next clamping step. It can also move the product placement piece 225 to the left or right side after the workpiece has been processed, making it convenient to remove the processed workpiece and place a new workpiece. The lifting module 220 is located between the two conveyor belt structures, ensuring that the product placement piece 225 does not collide with the workpiece transmission assembly 230 when the movable platform 223 moves the product placement piece 225 upwards.

[0036] It is understandable that, such as Figure 3 As shown, when a housing 800 is provided, a window can be opened on the housing 800 to facilitate placing the workpiece to be processed on the left side of the workpiece transmission assembly 230, and processing is carried out in the middle. After processing is completed, the workpiece is output from the right side, thus forming a cycle.

[0037] In some specific embodiments of this utility model, the moving mechanism 100 includes a front-to-back moving module 110, a left-to-right moving module 120 is provided at the transmission end of the front-to-back moving module 110, a first support 130 is provided at the transmission end of the left-to-right moving module 120, the first support 130 has an L-shaped structure, the horizontal section of the first support 130 is connected to the transmission end of the left-to-right moving module 120, the vertical section of the first support 130 is provided with an up-and-down moving module 140, the transmission end of the up-and-down moving module 140 is provided with a connecting plate 150, and the pin-pulling mechanism 300 and the locking mechanism 500 are arranged side by side on the connecting plate 150.

[0038] like Figure 1 and Figure 6As shown, in this embodiment, the forward and backward moving module 110 can drive the left and right moving module 120, the first support 130, the up and down moving module 140, the connecting plate 150, the pin-pulling mechanism 300, and the locking mechanism 500 to move in the forward and backward direction. The left and right moving module 120 can drive the first support 130, the up and down moving module 140, the connecting plate 150, the pin-pulling mechanism 300, and the locking mechanism 500 to move in the left and right direction. The up and down moving module 140 can drive the connecting plate 150, the pin-pulling mechanism 300, and the locking mechanism 500 to move in the up and down direction. In this way, the forward and backward moving module 110, the left and right moving module 120, and the up and down moving module 140 can achieve the precise movement of the pin-pulling mechanism 300 above the workpiece and the precise movement of the locking mechanism 500 between the workpiece and the feeding mechanism 600.

[0039] It is understandable that, such as Figure 2 As shown, the pin-pulling mechanism 300 and the locking mechanism 500 can be arranged on the front and rear sides of the connecting plate 150 to reduce space occupation and make the overall structure more compact.

[0040] In some specific embodiments of this utility model, the front-to-back moving module 110 includes a first moving component 111, a first transmission component 112 and a first connecting member 113. The first moving component 111 and the first transmission component 112 are arranged side by side, the first connecting member 113 is straddling the first moving component 111 and the first transmission component 112, and the left-to-right moving module 120 is arranged on the first connecting member 113.

[0041] like Figure 6 and Figure 7 As shown, in this embodiment, the first moving component 111 is a guide rail slider structure with a motor drive. The motor can drive the moving end of the guide rail slider to move the first connecting member 113 in the front-back direction. The first transmission component 112 is a guide rail slider structure that can cooperate with the first moving component 111 to support and connect the first connecting member 113. In addition, it can cooperate with the first moving component 111 to allow the first connecting member 113 to move more smoothly in the front-back direction.

[0042] It is understandable that the forward and backward moving module 110 may also be provided with a plurality of first limiting members 114, which are respectively located at the front and rear ends of the first moving component 111 and the first transmission component 112. The setting of the first limiting members 114 can limit the moving distance of the first connecting member 113 and prevent it from overtraveling. It is also understandable that the first moving component 111 may also adopt a cylinder-driven guide rail slider structure.

[0043] In some specific embodiments of this utility model, the left and right moving module 120 includes a second moving component 121 and a second transmission component 122 arranged side by side. The second moving component 121 and the second transmission component 122 are fixedly arranged on the front and rear moving module 110. The horizontal section of the first bracket 130 is connected to the second moving component 121 and the second transmission component 122.

[0044] like Figure 6 and Figure 8 As shown, in this embodiment, the second moving component 121 is a guide rail slider structure with a motor drive. The motor can drive the moving end of the guide rail slider to move the first bracket 130 in the left and right directions. The second transmission component 122 is a guide rail slider structure, which can cooperate with the second moving component 121 to support and connect the first bracket 130. In addition, the cooperation with the second moving component 121 can make the first bracket 130 move more smoothly in the left and right directions on the second transmission component 122.

[0045] It is understandable that the left and right moving module 120 may also be provided with a number of second limiting members 123, which are respectively located at the left and right ends of the second moving component 121 and the second transmission component 122. The setting of the second limiting members 123 can limit the moving distance of the first bracket 130 and prevent it from overtraveling. It is also understandable that the second transmission component 122 may also adopt a cylinder-driven guide rail slider structure.

[0046] In some specific embodiments of this utility model, the up-down moving module 140 includes a second connecting member 141. The rear side of the second connecting member 141 is connected to the vertical section of the first bracket 130. The front side of the second connecting member 141 is provided with a third moving component 142 and a third transmission component 143 arranged side by side. The connecting plate 150 spans the third moving component 142 and the third transmission component 143.

[0047] like Figure 6 and Figure 9 As shown, in this embodiment, the third moving component 142 and the third transmission component 143 are disposed on the second connector 141. The third moving component 142 is a guide rail slider structure with motor drive. The motor can drive the moving end of the guide rail slider to move the connecting plate 150 in the vertical direction. The third transmission component 143 is a guide rail slider structure, which can cooperate with the third moving component 142 to support and install the connecting plate 150. In addition, the third moving component 142 can make the connecting plate 150 move more smoothly in the vertical direction on the third transmission component 143.

[0048] It is understandable that the second connecting member 141 facilitates the formation of an integrated structure for the vertical moving module 140 and allows for the placement of the third moving component 142 and the third transmission component 143. It is also understandable that the vertical moving module 140 may be equipped with several third limiting members 144, located at the upper and lower ends of the third moving component 142 and the third transmission component 143 respectively. The third limiting members 144 limit the movement distance of the connecting plate 150, preventing it from overtraveling. It is also understandable that the third moving component 142 may also employ a cylinder-driven guide rail slider structure.

[0049] It is understandable that the first moving assembly 111, the second moving assembly 121, and the third moving assembly 142 can adopt the same structure but different sizes of motor sliding rails to improve assembly convenience. It is also understandable that the first transmission assembly 112, the second transmission assembly 122, and the third transmission assembly 143 can adopt the same structure but different sizes of guide rail sliders to improve assembly convenience. Furthermore, it is understandable that the first limiting member 114, the second limiting member 123, and the third limiting member 144 can use the same parts to improve interchangeability.

[0050] In some specific embodiments of this utility model, a pre-tensioning component output mechanism 400 is also included. The pre-tensioning component output mechanism 400 is disposed on the side close to the pin pulling mechanism 300. The pre-tensioning component output mechanism 400 includes a fourth transmission assembly 410. The input end of the fourth transmission assembly 410 is provided with a guide receiving member 420, and the output end of the fourth transmission assembly 410 is provided with a storage box 430.

[0051] like Figure 1 and Figure 10 As shown, in this embodiment, the fourth transmission component 410 is a conveyor belt structure driven by a motor, which can receive the pre-tensioned component and transport it into the storage box 430. The guide receiving component 420 is set at an obtuse angle to the transmission direction of the fourth transmission component 410, and can cooperate with the fourth transmission component 410 to receive the pre-tensioned component and prevent the pre-tensioned component from falling out when it enters the fourth transmission component 410.

[0052] Understandably, a stand 440 can also be provided below the storage box 430 to facilitate adjusting the height of the storage box 430, thereby facilitating the reception of the pre-tensioning component transmitted from the fourth transmission assembly 410.

[0053] In some specific embodiments of this utility model, the feeding mechanism 600 includes at least one circular vibrating feeder 610. The output end of the circular vibrating feeder 610 is provided with a feeding track 620. The bottom end of the feeding track 620 is provided with a vibrator 630. The output end of the feeding track 620 is provided with a material distribution structure 640, which is suitable for placing fasteners.

[0054] like Figure 1 and Figure 11 As shown, in this embodiment, a total of six circular vibrating feeders 610 are provided, and each circular vibrating feeder 610 is equipped with a feeding track 620. Each feeding track 620 is equipped with a vibrator 630, and its output end is provided with a material distribution structure 640.

[0055] When the equipment is running, the required fasteners are placed into the corresponding circular vibrating feeder 610. The circular vibrating feeder 610 can orderly convey the fasteners to the feeding track 620, and the vibrator 630 vibrates the fasteners on the feeding track 620 to keep them upright and stably convey them to the distribution structure 640, so that the moving mechanism 100 can drive the locking mechanism 500 to pick up the fasteners, and after the locking mechanism 500 takes away a fastener, a new fastener can be immediately added to the distribution structure 640.

[0056] Understandably, by setting up multiple circular vibratory feeders 610, various screw sizes can be accommodated, thereby improving the applicability of the device. When performing locking operations on different types of workpieces, it is not necessary to empty the existing fasteners within the feeding mechanism 600 before starting the operation. Understandably, the feeding mechanism 600 can adopt a screw feeding mechanism based on the JOFR-828ZMC.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model 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 the present utility model.
