DETAILED DESCRIPTION

[0028] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0029] The utility model discloses a sheet feeding device, which enables a first sheet feeding mechanism to place two sheets on a second sheet feeding mechanism each time, and then a flow channel removal mechanism performs flow channel removal work on the two sheets each time, thereby greatly reducing the volumes of the second feeding mechanism and the flow channel removal mechanism, and solving the problem of the large overall volume of existing semiconductor automated injection molding equipment.

[0030] like Figure 1 The blank unloading device shown is installed on the injection molding machine 400 through the mounting plate of the frame, and the blank unloading device includes: a first blank unloading mechanism 100, a second blank unloading mechanism 200 and a runner removal mechanism 300 which are arranged in sequence.

[0031] The first blank unloading mechanism 100 comprises: a first blank displacement component 101, a first blank lifting component 102 and a first blank clamping component 103 connected in sequence, one end of the first blank displacement component 101 extends into the injection molding machine 400, wherein the first blank lifting component 102 is as shown in FIG. Figure 1-3 The cylinder or hydraulic cylinder shown, such as Figure 3 The two first web lifting assemblies 102 are connected to the first web clamping plates 1031 of the first web clamping assembly 103 via a crossbeam.

[0032] The second sheet feeding mechanism 200 comprises: a second sheet displacement assembly 201 and a lower fixture 202 for removing the flow channel connected in sequence, and the lower fixture 202 for removing the flow channel is provided with two sets of sheet positioning parts.

[0033] The deflowing mechanism 300 includes: a deflowing lifting component 301 and a deflowing upper fixture 302 connected in sequence, and the deflowing upper fixture 302 is provided with two groups of deflowing cutting parts, and the two groups of deflowing cutting parts cooperate with two groups of sheet positioning parts, wherein the deflowing lifting component 301 is a cylinder or a hydraulic cylinder.

[0034] The first sheet material unloading mechanism 100 is used to place two sheets on the lower deflow fixture 202, the second sheet material unloading mechanism 200 is used to move the two sheets to below the upper deflow fixture 302, and the deflow lifting assembly 301 is used to drive the upper deflow fixture 302 to perform deflow work on the two sheets.

[0035] In this embodiment, two groups of sheet positioning parts are arranged side by side along the width direction of the two sheets, and two groups of flow channel removal cutting parts are arranged side by side along the width direction of the two sheets.

[0036] Regarding the first sheet displacement component 101, as Figure 1-3 The first web displacement assembly 101 shown includes: a first web displacement motor 1013 , a first web displacement lead screw mechanism 1011 and a first web displacement guide rail 1012 .

[0037] The first web displacement motor 1013 , the first web displacement lead screw mechanism 1011 and the first web displacement guide rail 1012 are installed on the injection molding machine 400 , and the first web displacement lead screw mechanism 1011 is connected to the first web displacement motor 1013 .

[0038] The two first web displacement guide rails 1012 are respectively disposed on two sides of the first web clamping assembly 103 .

[0039] One of the first web displacement guide rails 1012 is disposed above the first web displacement lead screw mechanism 1011 and is connected to the first web displacement lead screw mechanism 1011 .

[0040] Another first web displacement guide rail 1012 is disposed above the second web displacement assembly 201 .

[0041] like Figure 1 As shown, the first sheet displacement motor 1013, the first sheet displacement screw mechanism 1011 and the first sheet displacement guide rail 1012 are installed on the injection molding machine 400 through the mounting plate of the frame. Figure 1-3 The first web displacement guide rail 1012 is arranged above the second web displacement assembly 201 through a pad, and the two first web displacements are connected through the first web lifting assembly 102 and the first web clamping assembly 103 .

[0042] By arranging the first sheet displacement guide rail 1012 above the second sheet displacement assembly 201, the sheet on the first sheet clamping assembly 103 can be placed on the deflow channel lower fixture 202 without arranging a cantilever. The space above the deflow channel lower fixture 202 is utilized to further reduce the horizontal plane area occupied by the sheet feeding device and improve the stability of the sheet feeding device.

[0043] Regarding the first web clamping assembly 103 , the first web clamping assembly 103 includes: a first web clamping plate 1031 , a first web clamping guide rail 1032 , a first web clamping claw 1033 and a first web clamping cylinder 1034 .

[0044] The first material clamping plate 1031 is installed on the first material lifting assembly 102, the first material clamping guide rail 1032 and the first material clamping cylinder 1034 are installed on the first material clamping plate 1031, the first material clamping jaw 1033 is installed on the first material clamping guide rail 1032, the first material clamping jaw 1033 is connected to the first material clamping cylinder 1034, and the end of the first material clamping jaw 1033 away from the first material clamping cylinder 1034 passes through the first material clamping plate 1031, and the end thereof passing through the first material clamping plate 1031 is used to clamp the material.

[0045] The number of the first sheet clamping jaws 1033 is eight groups, and the number of the first sheet clamping cylinders 1034 matches the number of the first sheet clamping jaws 1033. The first sheet clamping cylinders 1034 are used to drive the first sheet clamping jaws 1033 to clamp the eight sheets in the injection molding machine 400, wherein each group of the first sheet clamping jaws 1033 includes two jaws, with a total of sixteen jaws. The number of the first sheet clamping cylinders 1034 can be four, eight or sixteen, which matches the number of the first sheet clamping jaws 1033.

[0046] The eight groups of first sheet clamps 1033 can be used to take out the sheets in the injection molding machine 400 at one time. When the first sheet clamping assembly 103 places the sheets in groups of two on the runner lower fixture 202, the injection molding machine 400 performs the next group of sheet packaging work, which enables the sheet unloading device to use the strategy of exchanging time for space without affecting the working efficiency of the entire semiconductor automated injection molding equipment.

[0047] In such Figure 4 In the further embodiment shown, the first web clamping assembly 103 further includes: a web clamping connecting rod 1035 , which is used to connect two adjacent first web clamping jaws 1033 .

[0048] The number of the first web clamping cylinders 1034 is four, so that each first web clamping cylinder 1034 drives two groups of first web clamping jaws 1033 to work at the same time.

[0049] The first sheet clamping assembly 103 puts down two sheets at a time at one position through the first sheet clamping cylinder 1034, thereby improving the efficiency of sheet placing, reducing the number of first sheet clamping cylinders 1034, reducing the cost of the material unloading device, reducing the weight of the first sheet clamping assembly 103, and enabling the first sheet lifting assembly 102 to select a low-load and low-cost cylinder, further reducing the cost of the material unloading device.

[0050] Regarding the second sheet displacement assembly 201, as Figure 1-3 The second web displacement assembly 201 shown includes: a second web displacement motor 2013 , a second web displacement synchronous belt mechanism 2011 and a second web displacement guide rail 2012 .

[0051] The second web displacement motor 2013 , the second web displacement timing belt mechanism 2011 and the second web displacement guide rail 2012 are installed on the injection molding machine 400 , and the second web displacement timing belt mechanism 2011 is connected to the second web displacement motor 2013 .

[0052] like Figure 2 and 3 The lower fixture 202 for removing the flow channel is installed on the second sheet displacement synchronous belt mechanism 2011 and the second sheet displacement guide rail 2012.

[0053] Working principle: First, through the cooperation of the first sheet displacement component 101, the first sheet lifting component 102 and the first sheet clamping component 103 of the first sheet unloading mechanism 100, the eight sheets in the injection molding machine 400 are moved to the top of the second sheet unloading mechanism 200, and through the cooperation of the first sheet displacement component 101 and the second sheet displacement component 201, the runner lower fixture 202 is moved to a position that cooperates with the first sheet clamping component 103.

[0054] Then, the two sheets on the first sheet clamping assembly 103 are placed on the deflow channel lower fixture 202 through the cooperation of the first sheet lifting assembly 102 and the first sheet clamping assembly 103, and then the second sheet displacement assembly 201 moves the two sheets on the deflow channel lower fixture 202 to the position below the deflow channel upper fixture 302.

[0055] Then, the flow channel removal lifting component 301 drives the flow channel removal upper fixture 302 to perform flow channel removal on the two sheets on the flow channel removal lower fixture 202 .

[0056] After four times of cooperation between the first sheet unloading mechanism 100 and the second sheet unloading mechanism 200, the second sheet displacement assembly 201 moves the eight sheets on the first sheet clamping assembly 103 to the position below the de-runner upper fixture 302 in four times, so that the de-runner upper fixture 302 performs de-runner work on the eight sheets in four times, which greatly reduces the volume of the second unloading mechanism and the de-runner mechanism 300, thereby reducing the overall volume of the semiconductor automated injection molding equipment.

[0057] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
