Detailed Description
In order that the invention may be readily understood, a more complete description of the invention will be rendered by reference to the appended drawings. The drawings illustrate preferred embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only. The terms "first," "second," "third," and "fourth" in this disclosure do not denote a particular quantity or order, but rather are used for distinguishing between similar or identical items.
As shown in fig. 1 and 2, the automatic hinge arm assembly machine according to an embodiment of the present invention includes a frame 100, an index plate 110, a four-hole assembly mechanism 200, a spring assembly mechanism 300, a first rivet assembly mechanism 400, a spring detection mechanism 500, and a finished product blanking sort mechanism 600. The index plate 110 is mounted on the frame 100. The index plate 110 is provided with a plurality of assembly stations 113 (see fig. 4 and 5) for placing the straight arms 701 (see fig. 3). The four-hole assembly mechanism 200, the spring detection mechanism 500, and the finished product blanking sort mechanism 600 are disposed around the index plate 110. The four-hole fitting mechanism 200 is used to fit four-hole pieces to the straight arm 701, the spring fitting mechanism 300 is used to fit springs to the straight arm 701, and the first rivet fitting mechanism 400 is used to fit first rivets to the straight arm 701.
The spring detection mechanism 500 is used to detect whether the spring is located within the straight arm 701. Referring to fig. 14, the finished product blanking sort mechanism 600 includes a hooking assembly 610 and a bin 620. The hooking member 610 has a first operational state and a second operational state. When the hooking component 610 is in the first working state, the hooking component 610 hooks the straight arm 701 on the index plate 110 into the bin 620. When the hooking component 610 is in the second working state, the hooking component 610 hooks the straight arm 701 out of the index plate 110 and does not hook into the bin 620.
In the automatic assembly machine for hinge arm assemblies, the straight arm 701 is mounted on the assembly station 113 on the index plate 110. After the straight arm 701 is assembled with the four-hole piece, the spring, and the first rivet, the straight arm 701 rotates with the index plate 110 to the spring detection mechanism. If the spring detection mechanism detects that the spring is located in the straight arm 701, the hooking assembly 610 hooks the straight arm 701 located on the index plate 110 into the bin 620 as the index plate 110 is rotated to the finished product blanking and sorting mechanism 600. If the spring detection mechanism detects that the spring is not located in the straight arm 701, the straight arm 701 is a defective product, the straight arm 701 is not assembled any more subsequently, and meanwhile, when the straight arm 701 rotates to the finished product blanking and sorting mechanism along with the index plate 110, the hooking component 610 hooks the straight arm 701 out of the index plate 110 and does not hook into the bin 620, so that continuous processing on the defective product is avoided, and materials are saved.
In addition, the hinge arm assembly is assembled by manual work and simple tools in most of the household hardware hinge industry, and the problems of low production efficiency, high manufacturing cost and high labor intensity of staff exist. The traditional assembly machine has an index plate and module linear carrying mode or a foreign annular full-automatic assembly line mode, but the traditional assembly machine has huge machine, high manufacturing cost, no detection function, defective products and good product mixing, and high requirements on stamping of a former process die, and high technical transformation cost. The automatic assembly machine for the hinge arm assembly has the advantages of small machine table size, high benefit and low input cost. Moreover, the automatic assembly machine for the hinge arm assembly is high in automation degree, and one worker can see a plurality of machines.
In one embodiment, in conjunction with fig. 3, the hinge arm assembly robot further includes an arm feed mechanism 120 located beside the indexing plate 110. The arm feeding mechanism 120 comprises an arm vibration disc 121, an arm material channel 122 and a pushing piece 123, wherein the inlet end of the arm material channel 122 is communicated with the outlet of the arm vibration disc 121, a proximity switch 124 is arranged at the outlet end of the arm material channel 122, and the pushing piece 123 is used for pushing a straight arm 701 at the outlet end to the assembly station 113 of the index plate 110. When the arm vibration plate 121 automatically discharges and the straight arm 701 reaches the outlet end of the arm channel 122, the proximity switch 124 detects the straight arm 701, and the pusher 123 pushes the straight arm 701 onto the assembly station 113 of the index plate 110. The proximity switch 124 can be provided with the straight arm 701 on the assembly station 113, so that assembly on the empty assembly station 113 in the subsequent process is avoided, and waste of materials is avoided.
It is understood that the pushing member 123 may be a cylinder, an oil cylinder, or a motor. Wherein, the arm material channel 122 can be a round belt. The arm path 122 is connected to a drive motor 125. The drive motor 125 is used to control the conveying speed of the arm lane 122.
Specifically, referring to fig. 4 and 5, a divider 114 is installed below the dividing plate 110, and the divider 114 is connected with a brake motor 115, so that the brake motor 115 drives the divider 114 to move, and further drives the dividing plate 110 to rotate, so that the straight arm 701 on the assembly station 113 is conveyed to different stations for assembly. Wherein the indexing plate 110 is provided with a positioning hole 116. When the locating posts extend into the locating holes 116, the locating posts can prevent the index plate 110 from rotating, ensuring that the straight arm 701 is stationary so that other parts can be assembled to the straight arm 701.
In one embodiment, referring to fig. 6 and 7, the hinge arm assembly automatic assembling machine further includes an adjusting screw assembling mechanism 130 and a height detecting mechanism 140 sequentially disposed along the rotation direction of the index plate 110. The adjusting screw fitting mechanism 130 and the fixed-height detecting mechanism 140 are located upstream of the four-hole fitting mechanism 200, and the adjusting screw fitting mechanism 130 is used to fit the adjusting screw to the straight arm 701.
The fixed-height detecting mechanism 140 includes a first driving member 141, a screw pressing member 142, a swing rod 143, and a fixing frame 144. The swing rod 143 is rotatably arranged on the fixed frame 144 through a rotating shaft 145, a first end of the swing rod 143 is connected with a screw pressing piece 142, the distance between the screw pressing piece 142 and the rotating shaft 145 is smaller than the distance between a second end of the swing rod 143 and the rotating shaft 145, and the first driving piece 141 is used for driving the screw pressing piece 142 to move so that the screw pressing piece 142 abuts against an adjusting screw arranged on the straight arm 701.
Referring to fig. 7, when the height detection mechanism 140 detects whether the adjusting screw is in place, the first driving member 141 drives the screw pressing member 142 to move so that the screw pressing member 142 abuts against the adjusting screw mounted on the straight arm 701, the first end of the swing link 143 moves along with the screw pressing member 142, and the second end of the swing link 143 swings along with the opposite direction. When the mounting height of the adjusting screw is higher or lower, the travel distance of the screw pressing member 142 is changed, and the travel distance of the second end of the swing rod 143 is also changed. Because the distance between the screw pressing piece 142 and the rotating shaft 145 is smaller than the distance between the second end of the swing rod 143 and the rotating shaft 145, according to the lever principle, the stroke fluctuation of the second end of the swing rod 143 is larger than the stroke fluctuation of the screw pressing piece 142, so that the installation error of the adjusting screw is amplified, whether the adjusting screw is installed in place or not can be detected more conveniently according to the stroke fluctuation of the second end of the swing rod 143, and the installation height is correct or not. Since the mounting height error of the adjusting screw may be in the range of 0.1mm, if it is very difficult to directly measure the mounting height error of the adjusting screw, the height-determining detecting mechanism 140 can conveniently detect whether the adjusting screw is mounted in place by amplifying the error stroke, for example, by 10 times, by means of the swing lever 143.
The end surface of the screw pressing member 142, which is close to the straight arm 701, is provided with an adjustable screw, so that the distance between the screw pressing member 142 and the straight arm 701 is adjustable, and different detection requirements can be met. The screw pressing piece 142 can realize a movement stroke in a mode that the sliding block is matched with the guide rail, so that the screw pressing piece 142 is more stable and reliable in working. The first driving member 141 may be a cylinder, an oil cylinder, or a motor.
Specifically, in connection with fig. 6, the adjusting screw assembly mechanism 130 includes a screw vibration plate 131, a screw distributor block 132, a screw block driver 133, and a screwing tool 134. The screw distributor block 132 is located at the outlet end of the screw vibration plate 131, and a screw block driving member 133 is connected to the screw distributor block 132, and the screw block driving member 133 is used for driving the screw distributor block 132 to slide so that the screw distributor block 132 pushes the adjusting screw to drop into the screwing tool 134. The screwing tool 134 installs the adjusting screw into the threaded hole of the straight arm 701. The screw block driving part 133 may be a cylinder driving part or a motor driving part. The screwing tool 134 may be selected from a power tool (commonly known as an electric screwdriver) and a pneumatic tool (commonly known as a pneumatic screwdriver).
Further, referring to fig. 6, the adjusting screw assembling mechanism 130 further includes a screw clamp 135, a clamp driving member 136, a first guide pin 137, a first pin driving member 138, and a first arm pressing cylinder 139, wherein the screw clamp 135 is located above the straight arm 701, and the screw clamp 135 is configured to receive an adjusting screw pushed down by the screw distributor block 132. The clamp driving member 136 is used for driving the screw clamp 135 to move downwards, the first guide pin 137 is located below the straight arm 701, the first needle driving member 138 is connected with the first guide pin 137, the first needle driving member 138 is used for driving the first guide pin 137 to move so that the first guide pin 137 can abut against an adjusting screw located in the screw clamp 135 after passing through a threaded hole of the straight arm 701, the first arm pressing cylinder 139 is connected with the screw screwing tool 134, the first arm pressing cylinder 139 is used for driving the screw screwing tool 134 to move downwards, and the screw screwing tool 134 is used for installing the adjusting screw in the screw clamp 135 into the threaded hole of the straight arm 701. If the first pin 137 is able to abut the adjustment screw, indicating that the adjustment screw is to the threaded bore of the alignment arm 701, the screw-driving tool 134 is activated and the adjustment screw can be accurately installed into the threaded bore.
