Description

Technical Field

[0002] In the related art, manual assembly is typically used to assemble workpieces such as left and right side covers and headrests to form an assembly. During the assembly process, the operator needs to use external tools such as a mallet to strike the left and right side covers. If the operator applies too much force, the left and right side covers may break, resulting in significant wear and tear. If the operator applies too little force, the left and right side covers may become loose, resulting in a low yield rate for the assembly. Therefore, how to effectively address the issues of high wear and tear and low yield rate caused by manual assembly of workpieces has become an urgent issue to be addressed. Utility Model Content

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0036] Please refer to Figure 1-Figure 5 As shown, the present application proposes a workpiece assembly device 1 with high production efficiency, low loss, and high yield rate.

[0037] The workpiece assembly device 1 includes a frame 10, a jig 20, a pressing mechanism 30, and an assembly mechanism 40. The jig 20 is mounted on the frame 10 and is used to carry a first workpiece to be assembled and a second workpiece to be assembled. The pressing mechanism 30 is mounted on the frame 10 and is configured to press the second workpiece to be assembled when the first workpiece to be assembled and the second workpiece to be assembled are carried on the jig 20, so as to position the second workpiece to be assembled on the first workpiece to be assembled. The assembly mechanism 40 is mounted on the frame 10 and is configured to assemble the first workpiece to be assembled and the second workpiece to be assembled into a combined body after the pressing mechanism 30 has positioned the second workpiece to be assembled on the first workpiece to be assembled.

[0038] The following combination Figures 1-9 The specific structure of the workpiece assembly device 1 is introduced in detail. It should be noted that the workpiece assembly device 1 in the embodiment of the present application can be used to assemble a first workpiece to be assembled and a second workpiece to be assembled of different product forms, and can also be used to assemble a first workpiece to be assembled and a second workpiece to be assembled of the same product form. For example, when the product forms of the first workpiece to be assembled and the second workpiece to be assembled are different, the first workpiece to be assembled can include but is not limited to the headrest 2b to be assembled (such as Figure 3As shown in the figure), buttons or gaskets to be assembled, etc.; the second workpiece to be assembled may include, but is not limited to, left and right side covers 2a to be assembled, latches to be assembled, buttons to be assembled, etc. For another example, when the first workpiece to be assembled and the second workpiece to be assembled have the same product form, the first workpiece to be assembled may include, but is not limited to, male buckles to be assembled, etc.; the second workpiece to be assembled may include, but is not limited to, female buckles to be assembled, etc.

[0039] like Figure 1-Figure 3 As shown, the workpiece assembly equipment 1 includes a frame 10 , a fixture 20 , a pressing mechanism 30 and an assembly mechanism 40 .

[0040] The frame 10 serves as the frame of the workpiece assembly apparatus 1. The specific structure of the frame 10 is not limited here, and designers can reasonably design it according to actual needs. For example, the frame 10 includes a workbench 11 and a cover 12. The fixture 20, the limit mechanism 50 (described below), and the rivet gun mechanism 60 (described below) are all mounted on the workbench 11. The pressing mechanism 30 and the assembly mechanism 40 are mounted on the cover 12. The cover 12 is connected to the workbench 11 and covers the workbench 11 surface. The cover 12 can be a semi-enclosed structure with an opening on one side, or a fully enclosed structure with a door on one side.

[0041] The fixture 20 serves as a carrying mechanism of the workpiece assembly device 1 and is used to carry the first workpiece to be assembled and the second workpiece to be assembled. The specific structure of the fixture 20 will be described in detail below.

[0042] The fixture 20 is mounted on the rack 10. The specific connection method between the fixture 20 and the rack 10 is not limited here, and designers can reasonably design it according to actual needs. For example, the fixture 20 can be, but is not limited to, detachably connected to the rack 10 by at least one of screwing, snapping, or plugging. For another example, the fixture 20 can also be, but is not limited to, non-detachably connected to the rack 10 by welding, gluing, or riveting.

[0043] The pressing mechanism 30 serves as a positioning structure of the workpiece assembly device 1 and is used to position the second workpiece to be assembled carried on the fixture 20 on the first workpiece to be assembled. The specific structure of the pressing mechanism 30 will be described in detail below.

[0044] The pressing mechanism 30 is mounted on the frame 10. The specific connection method between the pressing mechanism 30 and the frame 10 (specifically, the aforementioned cover 12) is not limited herein, and designers may reasonably design it based on actual needs. For example, the pressing mechanism 30 may be, but is not limited to, detachably connected to the frame 10 via at least one of screwing, snapping, or plugging. For another example, the pressing mechanism 30 may be, but is not limited to, non-detachably connected to the frame 10 via welding, gluing, or riveting.

[0045] like Figure 4-Figure 5 As shown, the pressing mechanism 30 is configured to press the second workpiece to be assembled when the first workpiece to be assembled and the second workpiece to be assembled are carried on the jig 20 , so as to position the second workpiece to be assembled on the first workpiece to be assembled.

[0046] The assembly mechanism 40 is a structure in the workpiece assembly device 1 for assembling a first workpiece to be assembled and a second workpiece to be assembled, which are independent of each other, into a combined body. The specific structure of the assembly mechanism 40 will be described in detail below.

[0047] The assembly mechanism 40 is mounted on the frame 10. The specific connection method between the assembly mechanism 40 and the frame 10 (specifically, the cover 12 described above) is not limited herein, and designers may reasonably design it based on actual needs. For example, the assembly mechanism 40 may be, but is not limited to, detachably connected to the frame 10 via at least one of screwing, snapping, or plugging. For another example, the assembly mechanism 40 may be, but is not limited to, non-detachably connected to the frame 10 via welding, gluing, or riveting.

[0048] The assembly mechanism 40 is configured to assemble the first workpiece to be assembled and the second workpiece to be assembled into a combination after the pressing mechanism 30 positions the second workpiece to be assembled on the first workpiece to be assembled. It should be noted that, taking the second workpiece to be assembled as the left and right side covers 2a to be assembled and the first workpiece to be assembled as the headrest 2b to be assembled as an example, the left and right side covers 2 to be assembled include at least one of a buckle and a clamping hole, and the headrest 2b to be assembled includes at least the other of a buckle and a clamping hole; the left and right side covers 2a to be assembled and the headrest 2b to be assembled are placed on the jig 20, and the pressing mechanism 30 presses the left and right side covers 2a to be assembled to position the left and right side covers 2a to be assembled on the headrest 2b to be assembled; at this time, the buckle and the clamping hole are aligned, and the left and right side covers 2a to be assembled are engaged with the buckle and the clamping hole under the action of the assembly mechanism 40, thereby being assembled into a combination with the headrest 2b to be assembled.

[0049] Based on the workpiece assembly equipment 1 in the embodiment of the present application, the operator places the first workpiece to be assembled and the second workpiece to be assembled on the jig 20, the pressing mechanism 30 presses the second workpiece to be assembled to position the second workpiece to be assembled on the first workpiece to be assembled, and then the assembly mechanism 40 assembles the first workpiece to be assembled and the second workpiece to be assembled into an assembly; in this way, batch production of workpieces to be assembled is achieved, which can effectively reduce assembly errors caused by manual assembly, reduce the loss of workpieces to be assembled, improve the yield rate of the assembly, and can also effectively reduce personnel input and reduce costs.

[0050] like Figure 4-Figure 6As shown, the assembling mechanism 40 comprises a first driving member 41 and an assembling member 42; the first driving member 41 is installed on the frame 10; the assembling member 42 is installed on the driving end of the first driving member 41. After the pressing mechanism 30 positions the second workpiece to be assembled on the first workpiece to be assembled, the driving end of the first driving member 41 moves to the first preset direction OO' to make the assembling member 42 extrude the second workpiece to be assembled, so as to assemble the first workpiece to be assembled and the second workpiece to be assembled into a combination.

[0051] The first driving member 41 is used as the power source of the assembling mechanism 40 to drive the assembling member 42 to move along the first preset direction OO'; the specific form of the first driving member 41 is not limited here, and the designer can make reasonable design according to actual needs; for example, the first driving member 41 can include a pneumatic cylinder or a linear motor. The specific connection mode between the first driving member 41 and the frame 10 is not limited here, and the designer can make reasonable design according to actual needs; for example, the first driving member 41 can be fixedly connected with the frame 10 (specifically, the above-mentioned cover 12) by screwing, but is not limited to this.

[0052] The assembling member 42 is used as the extruding member of the assembling mechanism 40 to apply extrusion force to the second workpiece to be assembled, so that the second workpiece to be assembled is assembled with the first workpiece to be assembled into a combination under the action of the extrusion force; the assembling member 42 can be, but is not limited to, an assembling plate or an assembling block. The specific connection mode between the assembling member 42 and the driving end of the first driving member 41 is not limited here, and the designer can make reasonable design according to actual needs; for example, when the first driving member 41 includes a pneumatic cylinder, the telescopic rod of the pneumatic cylinder is connected with the assembling member 42 as the driving end of the first driving member 41, and the assembling member 42 can be, but is not limited to, fixedly connected with the telescopic rod of the pneumatic cylinder by at least one of screwing, clamping or inserting; for another example, when the first driving member 41 includes a linear motor, the mover of the linear motor is connected with the assembling member 42 as the driving end of the first driving member 41, and the assembling member 42 can be, but is not limited to, fixedly connected with the mover of the linear motor by at least one of screwing, clamping or inserting. It should be noted that, in order to avoid hard extrusion between the assembling member 42 and the second workpiece to be assembled, the assembling member 42 can be, but is not limited to, made of materials such as elastic rubber, elastic silica gel or elastic resin, so that the possibility of scratching the surface of the second workpiece to be assembled by the assembling member 42 can be effectively reduced or even avoided. Of course, the assembling member 42 itself can also be made of materials such as stainless steel or plastic, at this time, components such as elastic rubber pads (not shown in the figure), elastic silica gel pads (not shown in the figure) or elastic resin pads (not shown in the figure) can be additionally provided on the extruding surface of the assembling member 42, so as to effectively reduce or even avoid the possibility of scratching the surface of the second workpiece to be assembled by the assembling member 42 directly contacting the surface of the second workpiece to be assembled.

[0053] After the pressing mechanism 30 positions the second workpiece to be assembled on the first workpiece to be assembled, the driving end of the first driving member 41 moves along the first preset direction OO' to cause the assembly member 42 to squeeze the second workpiece to be assembled, and the second workpiece to be assembled is assembled into a combination with the first workpiece to be assembled under the squeezing action of the assembly member 42 to complete the assembly.

[0054] like Figure 3-Figure 6 As shown, the first and second workpieces to be assembled have multiple assembly locations 2c, and the projection of the assembly member 42 along the first preset direction OO' onto the first and second workpieces to be assembled covers all of the assembly locations 2c. The assembly mechanism 40 also includes multiple guide members 43, each corresponding to a location 2c to be assembled, and each guide member 43 is connected to the assembly member 42 and the frame 10. The driving end of the first driving member 41 moves in the first preset direction OO' to drive the assembly member 42 in the first preset direction OO', thereby causing all guide members 43 to move relative to the frame 10 in the first preset direction OO'.

[0055] The "pre-assembly positions 2c" are the corresponding connection points on the first and second workpieces to be assembled, used to assemble the first and second independent workpieces into a combined assembly. For example, if the second workpieces to be assembled are the left and right side covers 2a to be assembled, and the first workpiece to be assembled is the headrest 2b to be assembled, the "pre-assembly positions 2c" are the corresponding locations of the buckles and / or holes on the left and right side covers 2a to be assembled. The corresponding "pre-assembly positions 2c" are also the corresponding locations of the holes and / or buckles on the headrest 2b to be assembled.

[0056] The guide member 43 may include, but is not limited to, a guide rod or a guide block; for example, when the guide member 43 includes a guide rod, each guide rod extends along a first preset direction OO' and is slidably connected to the top wall of the cover shell 12, and the end of each guide rod may be, but is not limited to, fixedly connected to the assembly 42 by means of a locking screw; for another example, when the guide member 43 includes a guide block, each guide block may be, but is not limited to, fixedly connected to the assembly 42 by means of a locking screw, and the side wall of the cover shell 12 is provided with a plurality of guide rails that are slidably connected to the plurality of guide blocks in a one-to-one correspondence.

[0057] By designing the guide member 43, while the driving end of the first driving member 41 drives the assembly member 42 to move along the first preset direction OO' toward the second workpiece to be assembled, the guide member 43 also moves along the first preset direction OO'. The guide member 43 provides support for the movement of the assembly member 42 in the first preset direction OO', thereby enhancing the stability of the assembly member 42 in the first preset direction OO', thereby achieving effective extrusion of the second workpiece to be assembled by the assembly member 42. It should be noted that by designing the projection of the assembly member 42 along the first preset direction OO' on the first workpiece to be assembled and the second workpiece to be assembled to cover all the positions 2c to be assembled, so that when the assembly member 42 squeezes the second workpiece to be assembled under the action of the driving end of the first driving member 41, the assembly member 42 can effectively squeeze all the positions 2c to be assembled, thereby improving the yield rate of the assembly.

[0058] like Figure 4-Figure 6 As shown, the first driving member 41 includes a first cylinder 411 mounted on the frame 10; the telescopic rod of the first cylinder 411 serves as the driving end of the first driving member 41 and is connected to the assembly member 42. The telescopic rod of the first cylinder 411 extends along a first preset direction OO' to drive the assembly member 42 to move toward the second workpiece to be assembled and squeeze the second workpiece to be assembled, thereby assembling the first workpiece to be assembled and the second workpiece to be assembled into a combination. The first cylinder 411 can be fixed to the top wall of the housing 12 by, but is not limited to, screwing. By designing the first driving member 41 as the first cylinder 411, the telescopic rod of the first cylinder 411 is driven to extend along the first preset direction OO' to drive the assembly member 42 connected thereto to move along the first preset direction OO' toward the second workpiece to be assembled, the assembly member 42 squeezes the second workpiece to be assembled, and the second workpiece to be assembled is assembled into a combination with the first workpiece to be assembled under the squeezing action of the assembly member 42 to complete the assembly.

[0059] like Figure 4-Figure 6 As shown, the pressing mechanism 30 includes a second driving member 31 and a pressing member 32; the second driving member 31 is mounted on the frame 10; the pressing member 32 is mounted on the driving end of the second driving member 31. When the first workpiece to be assembled and the second workpiece to be assembled are supported on the jig 20, the driving end of the second driving member 31 moves along a second predetermined direction until the pressing member 32 presses the second workpiece to be assembled, thereby positioning the second workpiece to be assembled on the first workpiece to be assembled.

[0060] The second drive member 31 serves as the power source of the pressing mechanism 30 and is used to drive the pressing member 32 to move along the second predetermined direction. The specific form of the second drive member 31 is not limited here, and designers can reasonably design it according to actual needs. For example, the second drive member 31 can include a cylinder or a linear motor. The specific connection method between the second drive member 31 and the frame 10 is not limited here, and designers can reasonably design it according to actual needs. For example, the second drive member 31 can be, but is not limited to, fixedly connected to the frame 10 (specifically, the aforementioned cover 12) by screws.

[0061] The pressing member 32 is used as a positioning member of the pressing mechanism 30 to apply pressure to the second workpiece to be assembled so as to position the second workpiece to be assembled on the first workpiece to be assembled; the pressing member 32 can be, but is not limited to, a pressing plate or a pressing block. The specific connection method between the pressing member 32 and the driving end of the second driving member 31 is not limited here, and designers can make reasonable designs according to actual needs; for example, when the second driving member 31 includes a cylinder, the telescopic rod of the cylinder is connected to the pressing member 32 as the driving end of the second driving member 31, and the pressing member 32 can be, but is not limited to, fixedly connected to the telescopic rod of the cylinder by at least one of screw connection, clip connection or plug connection; for another example, when the second driving member 31 includes a linear motor, the mover of the linear motor is connected to the pressing member 32 as the driving end of the second driving member 31, and the pressing member 32 can be, but is not limited to, fixedly connected to the mover of the linear motor by at least one of screw connection, clip connection or plug connection. It should be noted that, in order to avoid a hard press between the pressing piece 32 and the second workpiece to be assembled, the pressing piece 32 can be made of, but is not limited to, materials such as elastic rubber, elastic silicone, or elastic resin. This can effectively reduce or even avoid the possibility of the pressing piece 32 scratching the surface of the second workpiece to be assembled. Of course, the pressing piece 32 itself can also be made of materials such as stainless steel or plastic. In this case, components such as another elastic rubber pad (not shown in the figure), another elastic silicone pad (not shown in the figure), or another elastic resin pad (not shown in the figure) can be added to the pressing surface of the pressing piece 32 to effectively reduce or even avoid the possibility of the pressing piece 32 directly contacting the surface of the second workpiece to be assembled and scratching the surface of the second workpiece to be assembled.

[0062] When the first workpiece to be assembled and the second workpiece to be assembled are placed on the jig 20, the driving end of the second driving member 31 moves along the second preset direction to make the pressing member 32 press the second workpiece to be assembled, and the second workpiece to be assembled is positioned on the first workpiece to be assembled under the pressing action of the pressing member 32 to achieve relative fixation of the positions between the first workpiece to be assembled and the second workpiece to be assembled.

[0063] like Figure 4-Figure 6As shown, the second driving member 31 includes a second cylinder 311 mounted on the frame 10; the telescopic rod of the second cylinder 311 serves as the driving end of the second driving member 31 and is connected to the pressing member 32. The telescopic rod of the second cylinder 311 extends along a second predetermined direction to drive the pressing member 32 toward the second workpiece to be assembled and press the second workpiece to be assembled, thereby positioning the second workpiece to be assembled on the first workpiece to be assembled. The second predetermined direction intersects with the first predetermined direction OO'. The second cylinder 311 can be fixed to the top wall of the housing 12 by, but is not limited to, screws. By designing the second driving member 31 as the second cylinder 311, the telescopic rod of the second cylinder 311 is driven to extend along the second predetermined direction to drive the pressing member 32 connected thereto to move along the second predetermined direction toward the second workpiece to be assembled. The pressing member 32 presses the second workpiece to be assembled, and the second workpiece to be assembled is positioned relative to the first workpiece to be assembled under the pressing action of the pressing member 32, thereby achieving relative fixation between the first and second workpieces to be assembled.

[0064] like Figure 7-Figure 8 As shown, the workpiece assembly device 1 also includes a limiting mechanism 50, which is mounted on the frame 10. When the first workpiece to be assembled is placed on the jig 20, a portion of the first workpiece to be assembled rests on the limiting mechanism 50, and the limiting mechanism 50 is used to limit the movement of the first workpiece to be assembled relative to the jig 20 along the third preset direction QQ'. By designing the limiting mechanism 50, when the first workpiece to be assembled is placed on the jig 20, a portion of the first workpiece to be assembled rests on the limiting mechanism 50, and the limiting mechanism 50 serves to limit the movement of the first workpiece to be assembled relative to the jig 20 along the third preset direction QQ'. In this way, the limiting mechanism 50 cooperates with the pressing mechanism 30 to effectively enhance the stability of the first workpiece to be assembled when placed on the jig 20.

[0065] Specifically, the limiting mechanism 50 includes a limiting seat 51, which can be fixed to the frame 10 by, but is not limited to, screws. The limiting seat 51 has a limiting groove 51a. When the first workpiece to be assembled is placed on the jig 20, a portion of the first workpiece to be assembled is embedded in the limiting groove 51a, and the first workpiece to be assembled rests on the bottom surface of the limiting groove 51a. The side surfaces of the limiting groove 51a, which are arranged relative to each other along the third preset direction QQ', abut against the second workpiece to be assembled, thereby limiting the movement of the second workpiece to be assembled relative to the jig 20 along the third preset direction QQ'. The third preset direction QQ' is perpendicular to the first preset direction OO'.

[0066] like Figure 2 、 Figure 4 、 Figure 5 and Figure 9As shown, the jig 20 includes a jig body 21 and a detection piece 22; the jig body 21 is installed on the frame 10, and the jig body 21 is used to carry the first workpiece to be assembled and the second workpiece to be assembled; the detection piece 22 is set on the jig body 21, and the detection piece 22 is configured to detect whether there is a burr 2d at a specified position of the first workpiece to be assembled after the pressing mechanism 30 positions the second workpiece to be assembled on the first workpiece to be assembled.

[0067] The jig body 21 is used to carry a first workpiece to be assembled and a second workpiece to be assembled, and the shape of the jig body 21 is adapted to the shape of the first workpiece to be assembled.

[0068] The detection member 22 is used as a detection unit of the jig 20 to detect whether there is a burr 2d at a designated position of the first workpiece to be assembled; the specific form of the detection member 22 will be described in detail below. The "designated position" can be understood as a processing position such as a glue injection port on the first workpiece to be assembled (e.g. Figure 9 As shown); it is understandable that when the melt of the plastic particles is injected in excess, after the melt of the plastic particles in the mold is cooled and formed, it is easy to cause burrs such as protrusions to be formed at the injection port 2d.

[0069] The detection member 22 is provided on the jig body 21. The operator places the first workpiece to be assembled and the second workpiece to be assembled on the jig body 21. The pressing mechanism 30 positions the second workpiece to be assembled on the first workpiece to be assembled. The detection member 22 then detects whether a burr 2d is present at a specified position on the first workpiece to be assembled. This enables the workpiece assembly device 1 to automatically identify burrs 2d.

[0070] like Figure 2 、 Figure 4 、 Figure 5 and Figure 9 As shown, the workpiece assembly equipment 1 also includes an early warning mechanism (not shown in the figure) and a control mechanism (not shown in the figure); the early warning mechanism is configured to issue an early warning prompt; the control mechanism is installed on the frame 10, and the control mechanism is electrically connected to the detection member 22, and the control mechanism is configured to control the early warning mechanism to issue an early warning prompt when the detection member 22 detects that there is a burr 2d at a designated position of the first workpiece to be assembled.

[0071] The control mechanism serves as the control center of the workpiece assembly device 1 and may include, but is not limited to, an MCU (Microcontroller Unit) and may be, but is not limited to, electrically connected to the detection member 22 via a wire.

[0072] The warning mechanism serves as an alarm module for the workpiece assembly apparatus 1. The warning mechanism is used to issue a warning prompt, and the operator, in response to the warning prompt, removes the first workpiece / assembly to be assembled from the jig 20 that has a burr 2d. The warning prompt may be, but is not limited to, a voice prompt, a light prompt, a text prompt, etc. It is understood that the specific manifestation of the corresponding warning mechanism varies depending on the form of the warning prompt. For example, when the warning prompt is a voice prompt, the warning mechanism may include, but is not limited to, a buzzer. When the detection component 22 detects a burr 2d at a designated location on the first workpiece to be assembled, the control mechanism controls the buzzer to sound. For another example, when the warning prompt is a light prompt, the warning mechanism may include, but is not limited to, an indicator light. When the detection component 22 detects a burr 2d at a designated location on the first workpiece to be assembled, the control mechanism controls the indicator light to flash. For another example, when the warning prompt is a text prompt, the warning mechanism may include, but is not limited to, a display. When the detection component 22 detects a burr 2d at a designated location on the first workpiece to be assembled, the control mechanism controls the display to display a warning message such as "Caution, Unqualified" or the like. On the contrary, when the detection member 22 does not detect the presence of the burr 2d at the designated position of the first workpiece to be assembled, the control mechanism will not control the warning mechanism to issue a warning prompt.

[0073] The warning mechanism can be installed on the rack 10, in which case the warning mechanism can be, but is not limited to, electrically connected to the control mechanism via wires; the warning mechanism can also be used alone, in which case the warning mechanism can be, but is not limited to, communicating with the control mechanism via Bluetooth.

[0074] By designing a control mechanism and an early warning mechanism, when the detection member 22 detects the presence of a burr 2d at a designated position of the first workpiece to be assembled, the control mechanism controls the early warning mechanism to issue an early warning prompt. The operator then removes the first workpiece / assembly to be assembled with the burr 2d carried on the jig 20 according to the early warning prompt, and performs manual or automatic mechanical deburring 2d on the removed first workpiece / assembly to be assembled. This can effectively reduce or even avoid the possibility of the burr 2d scratching the fabric in subsequent processes, thereby effectively improving the product yield.

[0075] Specifically, the specific forms of the detection element 22 may include, but are not limited to, the following embodiments.

[0076] In the first embodiment, the jig body 21 has a mounting hole, and the detection member 22 includes a button, which is at least partially arranged in the mounting hole, and the button is electrically connected to the control mechanism; when there is a burr 2d at the specified position of the first workpiece to be assembled, the button is pressed by the burr 2d and triggered, and the alarm circuit in the control mechanism is turned on. At this time, the control mechanism controls the early warning mechanism to issue an early warning prompt, and the operator removes the first workpiece / assembly to be assembled with the burr 2d carried on the jig 20 according to the early warning prompt, and performs manual or mechanical automatic deburring 2d processing on the removed first workpiece / assembly to be assembled; on the contrary, when there is no burr 2d at the specified position of the first workpiece to be assembled, the button is not triggered, the alarm circuit in the control mechanism is not turned on, and the control mechanism will not control the early warning mechanism to issue an early warning prompt.

[0077] In a second embodiment, the jig 20 has a mounting hole, and the detection member 22 includes a pressure sensor, which is at least partially arranged in the mounting hole, and the pressure sensor is electrically connected to the control mechanism; when there is a burr 2d at the specified position of the first workpiece to be assembled, the pressure sensor is squeezed and generates a warning signal. At this time, the control mechanism controls the warning mechanism to issue a warning prompt according to the warning signal, and the operator removes the first workpiece / assembly to be assembled with the burr 2d carried on the jig 20 according to the warning prompt, and performs manual or mechanical automatic deburring 2d processing on the removed first workpiece / assembly to be assembled; on the contrary, when there is no burr 2d at the specified position of the first workpiece to be assembled, the pressure sensor is not squeezed and no warning signal is generated. At this time, the control mechanism will not control the warning mechanism to issue a warning prompt.

[0078] like Figure 6 、 Figure 7 and Figure 9 As shown, the first workpiece to be assembled also has a position 2e for pulling nails; the workpiece assembly equipment 1 also includes a nail gun mechanism 60, which is installed on the frame 10. The nail gun mechanism 60 is configured to pull nails inserted in the position 2e for pulling nails after the pressing mechanism 30 positions the second workpiece to be assembled on the first workpiece to be assembled.

[0079] The "position 2e for inserting rivets" is the position for inserting rivets on the first workpiece to be assembled.

[0080] The rivet gun mechanism 60 includes a rivet gun 61 , which can be fixed to the frame 10 (specifically the above-mentioned workbench 11 ) by means of, but not limited to, screws.

[0081] By designing the rivet gun mechanism 60, the rivet gun mechanism 60 can pull the rivets inserted in the rivet position 2e after the pressing mechanism 30 positions the second workpiece to be assembled on the first workpiece to be assembled, so that the workpiece assembly equipment 1 has an automatic rivet pulling function.

[0082] It should be noted that the assembly operation of the assembly mechanism 40, the burr 2d detection operation of the detection piece 22, and the rivet pulling operation of the rivet gun mechanism 60 are all performed after the pressing mechanism 30 positions the second workpiece to be assembled on the first workpiece to be assembled, and the assembly operation of the assembly mechanism 40, the burr 2d detection operation of the detection piece 22 and the rivet pulling operation of the rivet gun mechanism 60 can be performed simultaneously or in sequence according to a preset order; there is no limitation here, and designers can make reasonable designs according to actual needs.

[0083] like Figure 1 As shown, the workpiece assembly apparatus 1 further includes a dual activation button 70, which is disposed on the frame 10. After the first and second workpieces to be assembled are placed on the jig 20, an operator can activate the dual activation button 70 with both hands, and the apparatus will resume normal operation. The dual activation button 70 is advantageous in that it prevents the operator from accidentally activating one of the buttons, potentially leading to accidents.

[0084] like Figure 1 As shown, the workpiece assembly device 1 further includes an emergency stop button 80, which is provided on the frame 10. During the operation of the device, if an accident occurs, the operator can trigger the emergency stop button 80 to immediately pause the device, thereby reducing the losses caused by the accident.

[0085] The following describes the working principle of the workpiece assembly device 1 by taking the second workpiece to be assembled as the left and right side covers 2a to be assembled and the first workpiece to be assembled as the headrest 2b to be assembled (the headrest 2b is used in a child safety seat) as an example, as follows:

[0086] Step 1: The operator places the headrest 2b and the left and right side covers 2a to be assembled on the jig body 21. The headrest 2b is partially embedded in the limiting groove 51a of the limiting seat 51, and the rivets are inserted into the rivet positions 2e of the headrest 2b. The operator then triggers the dual start button 70.

[0087] Step 2: The telescopic rod of the second cylinder 311 extends along a second preset direction to cause the pressing member 32 to press the left and right side covers 2a to be assembled, so as to position the left and right side covers 2a to be assembled on the headrest 2b to be assembled;

[0088] Step 3: The telescopic rod of the first cylinder 411 extends along the first preset direction OO' so that the assembly part 42 squeezes the left and right side covers 2a and the headrest 2b to be assembled. The left and right side covers 2a to be assembled are assembled into a combined body with the headrest 2b to be assembled under the squeezing action of the assembly part 42. The telescopic rod of the first cylinder 411 contracts along the first preset direction OO'; the detection part 22 detects whether there is a burr 2d at a specified position of the headrest 2b to be assembled; the rivet gun 61 pulls the rivets inserted in the rivet positions 2e of the headrest 2b to be assembled;

[0089] Step 4: The telescopic rod of the second cylinder 311 contracts along a second preset direction, and the operator takes the assembly out of the fixture body 21 .

[0090] This cycle repeats to achieve batch assembly.

[0091] It should be noted that in the above step 3, the first cylinder 411 drives the assembly part 42 to perform the assembly operation, the burr 2d detection operation of the detection part 22, and the rivet pulling operation of the rivet gun 61 can be performed simultaneously or in sequence according to a preset order. In the above step 3, if the detection part 22 detects that there is a burr 2d at the designated position of the headrest 2b to be assembled, the control mechanism will control the warning mechanism to issue a warning prompt, but the equipment will continue to work and will not pause midway; and after the assembly is completed, step 5 can also be included after step 4: the operator manually or mechanically removes the burrs 2d of the assembly. In any of the above steps 1 to 4, if an accident occurs, the operator can trigger the emergency stop button 80 in time to put the equipment into a pause state.
