[0002] Parts are metal or plastic parts with a volume less than 30·30mm. The characteristics of this type of parts are small size, light weight, and difficult to operate and control manually, but mechanical operation can easily cause them to rush out due to inertia or splash out when falling;

[0003] During the production process, parts need to be packaged according to a set weight. However, the parts are small in size, and manual weighing and packaging are not only labor-intensive, but also prone to errors. The traditional method of weighing with a conveying device and a weighing device is that the traditional conveying device is a transmission belt or a vibration device, which cannot accurately control small and light parts such as parts. Due to inertia, the parts are easily conveyed to the weighing device when the weighing device has reached the preset value. Too many parts fall into the packaging device, which not only causes losses to the manufacturer, but also too many parts easily damage the packaging, causing packaging damage that affects transportation.

DETAILED DESCRIPTION

[0025] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0026] like Figure 1 and Figure 2 As shown, a conveying device based on a point counting camera is used to deliver small parts. It has a feed bin 1 as an inlet and a storage hopper 2 as an outlet. The feed bin 1 is configured as a funnel shape and is connected to a shell 3 through L-shaped brackets on both sides. A first vibrating feeding unit 4 is provided at the end of the feed bin 1 in the shell 3, and a second vibrating feeding unit 5 is provided at the end of the first vibrating feeding unit 4. The storage hopper 2 is provided with a cover door driven by an opening and closing connecting rod. When the number of parts in the storage hopper 2 reaches the required number, the opening and closing connecting rod drives the cover door to open and deliver the parts inside.

[0027] The first vibration feeding unit 4 includes a first rough vibration trough 41 and a first fine vibration trough 42 arranged in parallel, and the second vibration feeding unit 5 is provided with a second rough vibration trough 51 and a second fine vibration trough 52. The first rough vibration trough 41 and the first fine vibration trough 42 simultaneously receive parts from the feed bin 1, and the cross-sections of the first fine vibration trough 42 and the second fine vibration trough 52 are set to a V-shaped structure and have the same width dimension and the width dimension is much smaller than the width dimension of the first rough vibration trough 41 and the second rough vibration trough 51, so that the first fine vibration trough 42 and the second fine vibration trough 52 can convey at most one part at any position in the length direction.

[0028] like Figure 3As shown, the feeding end of the first fine vibration trough 42 is also provided with an adjustment mechanism 43, and the adjustment mechanism 43 includes a flow-limiting baffle 431 arranged perpendicular to the length direction of the first fine vibration trough 42, and one end of the flow-limiting baffle 431 is hinged to the edge of the first fine vibration trough 42, so that the flow-limiting baffle 431 can swing around the hinged end to prevent too many parts from entering the first fine vibration trough 42 at the same time and causing blockage. In addition, an indicator plate 432 is vertically connected to the side of the flow-limiting baffle 431 away from the feeding end of the first fine vibration trough 42, and a notch is provided at one end of the indicator plate 432 away from the flow-limiting baffle 431, and a pointer is fixed on the first fine vibration trough 42 in the vertical direction, and the pointer passes through the notch and cooperates with the indicator plate 432 to display the opening angle of the flow-limiting baffle 431.

[0029] like Figure 4 As shown, the first vibration feeding unit 4 and the second vibration feeding unit 5 are connected with a vibration device for driving the movement of parts, including a first coarse vibrator 44 and a first fine vibrator 45 respectively connected to the first coarse vibration groove 41 and the first fine vibration groove 42, and a second coarse vibrator 53 and a second fine vibrator 54 respectively connected to the second coarse vibration groove 51 and the second fine vibration groove 52.

[0030] like Figure 2 As shown, an anti-splash channel 6 is provided between the discharge end of the second vibrating feeding unit 5 and the feed end of the storage hopper 2. In the present embodiment, there is a gap between the end of the anti-splash channel 6 away from the second vibrating feeding unit 5 and the feed end of the storage hopper 2. The detection end of the counting camera 7 provided in the shell 3 is provided corresponding to the gap for recording the number of parts passing through the gap.

[0031] The material quantity recorded by the counting camera 7 is set to A, and the incrementing preset values ​​A1, A2, and A3. In this embodiment, A1=0.9A3, and A2 is set to any value between A1 and A3.

[0032] When A2>A≥A1, the first coarse vibrator 44 and the second coarse vibrator 53 stop working, and the first fine vibrator 45 and the second fine vibrator 54 drive the parts in the first fine vibration trough 42 and the second fine vibration trough 52 into the storage hopper 2 respectively.

[0033] When A3>A≥A2, the first fine vibrator 45 also stops working, and only the second fine vibrator 54 drives the parts in the second fine vibration trough 52 into the storage hopper 2 one by one. Until the material quantity A recorded by the counting camera 7 reaches the preset value A3.

[0034] In other embodiments of the present application, one end of the anti-splash channel 6 close to the counting camera 7 is made of a transparent acrylic material, so that the counting camera 7 can directly record the number of parts passing through the anti-splash channel 6 through the acrylic material.

[0035] When using:

[0036] 1. Adjust the angle of the current limiting baffle 431 in the first fine vibration groove 42 to a suitable position.

[0037] 2. After the parts are put into the funnel-shaped feeding bin 1 by external equipment, a part of them falls into the first rough vibration trough 41 and the other part falls into the first fine vibration trough 42.

[0038] 3. The first rough vibrator 44 and the first fine vibrator 45 are started, so that the parts in the first rough vibration groove 41 and the first fine vibration groove 42 move toward the second rough vibration groove 51 and the second fine vibration groove 52 .

[0039] 4. The second rough vibrator 53 and the second fine vibrator 54 are started to deliver the parts in the second rough vibration trough 51 and the second fine vibration trough 52 into the storage hopper 2 through the anti-splash channel 6. At the same time, the counting camera 7 counts the parts passing through the anti-splash channel 6.

[0040] 5. When the number of parts A recorded by the counting camera 7 is between the preset values ​​A1 and A2, the first coarse vibrator 44 and the second coarse vibrator 53 stop working, and the first fine vibrator 45 and the second fine vibrator 54 respectively drive the parts in the first fine vibration trough 42 and the second fine vibration trough 52 into the storage hopper 2.

[0041] 6. When the number of parts A recorded by the counting camera 7 is between the preset values ​​A2 and A3, the first fine vibrator 45 also stops working, and only the second fine vibrator 54 drives the parts in the second fine vibration trough 52 to enter the storage hopper 2 one by one. Until the number of materials A recorded by the counting camera 7 reaches the preset value A3, then the cover door is opened to complete the accurate feeding of parts.

[0042] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
