[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0032] In the PACK (packaging) process of the 3C (computer, communications, and consumer electronics) industry, most battery cells and auxiliary materials are loaded from blister plastic trays. Due to the structural design of the trays and the particularities of the blister process, there will be differences in the edge cuts of the trays. In addition to the characteristics of the draft angle design, the trays may experience transportation errors and instability in the loading mechanism. In addition to causing deviations in the material position, the tray loading instability may also cause collapse during the loading process.

[0033] In addition, considering that the draft angle and blade of the material tray will be produced according to different blister forming processes and design factors, it is impossible to unify the draft angle and blade size. Using the blade surface as a reference position will result in inaccurate positioning. Because the blade is thin and the material tray is light, it is easy to collapse, causing precious materials to scatter and thus resulting in scrap.

[0034] The tray clamping mechanism and the demolding plastic tray loading device of the present application clamp and position the conveyed tray by pressing the tray downward and horizontally, thereby preventing the tray from shaking or even being carried away by the entire tray during subsequent material retrieval.

[0035] Figure 1 The structure diagram of a tray clamping mechanism provided in an embodiment of the present application is shown. Figure 2 An exploded view of a tray clamping mechanism provided in an embodiment of the present application is shown. Figure 3 The structure diagram of a mold-drawing plastic tray loading device provided in an embodiment of the present application is shown. Figure 4 The structure diagram of the tray of a mold-drawing plastic tray loading device provided in an embodiment of the present application is shown, wherein Figure 4 The figure shows the clamping mechanism holding one side of the tray. Figures 1 to 4 As shown, the tray clamping mechanism of the embodiment of the present application is used to clamp the side of the tray 2 without a cutting edge. The clamping mechanism 1 includes:

[0036] The fixed baffle 11 includes a first fixing portion 111 and a second fixing portion 112. The first fixing portion 111 is arranged horizontally, and the second fixing portion 112 is arranged at an angle to the first fixing portion 111. A first chute 1111 is provided on the top surface of the first fixing portion 111 away from the second fixing portion 112. A draft edge 21 is provided on the bottom surface of the side of the tray 2. The draft edge 21 slides along the first chute 111.

[0037] The first mounting plate 12 is connected to the second fixing portion 112 and includes a first positioning portion 121. The first positioning portion 121 is horizontally disposed directly above the first sliding groove 1111 and the first positioning portion 121 and the first positioning portion 121 extend in the same direction.

[0038] The first pressing plate 13 is located between the first positioning portion 121 and the first sliding groove 1111, and the top surface of the first pressing plate 13 is elastically connected to the bottom surface of the first positioning portion 121. The first pressing plate 13 is used to press the draft edge 21 downward when in contact with the top surface of the draft edge 21;

[0039] The second pressing plate 14 has one side elastically connected to the second fixing portion 112 , and the other side is used to press the material tray 2 along the horizontal direction when in contact with the material tray 2 .

[0040] In combination with the above embodiments, Figure 4 As shown, the left and right sides of the material tray are draft edges, and the clamping mechanism 1 is clamped on the corresponding draft edges. Since the two draft edges of the material tray 2 are arranged in parallel, the positioning reference of the clamping mechanism 1 is easier to locate than using the knife edge as the reference edge.

[0041] Furthermore, as the tray 2 slides along the first chute 1111, because the distance between the bottom surface of the first pressure plate 13 and the top surface of the first fixing portion 111 can be set to be less than the thickness of the tray 2's draft edge 21, when the tray 2 slides between the bottom surface of the first pressure plate 13 and the top surface of the first fixing portion 111, the draft edge 21 of the tray 2 presses the first pressure plate 13 upward, thereby causing the first pressure plate 13 to press the tray 2 downward under the action of the elastic force. Similarly, as the tray 2 slides along the first chute 1111, the second pressure plate 14 contacts the side of the tray 2 and, under the action of the elastic force, horizontally compresses the tray 2. By compressing the tray 2 in two directions (horizontally and vertically), the entire tray is less likely to be lifted up during material removal.

[0042] like Figure 1 and Figure 2 As shown, the material tray clamping mechanism of the embodiment of the present application, the clamping mechanism 1 also includes a first elastic structure 15 and a second elastic structure 16, and the first elastic structure 15 includes a first connecting member 151 and a first spring 152; first connecting holes are provided at both ends of the bottom surface of the first positioning portion 121, and second connecting holes are provided at both ends of the top surface of the first clamping plate 13, and the number of the first connecting holes is the same as that of the second connecting holes and corresponds one to one; the number of the first connecting members 151 is the same as that of the first connecting holes or the second connecting holes and corresponds one to one, and the two ends of each first connecting member 151 extend into the corresponding first connecting hole and the second connecting hole respectively; each first spring 152 is sleeved on the corresponding first connecting member 151, and the two ends are respectively pressed on the bottom surface of the corresponding first positioning portion 121 and the top surface of the first clamping plate 13.

[0043] like Figure 2As shown, the number of the first elastic structure 15 and the second elastic structure 16 can be set to one or more. When the number of the first elastic structure 15 and the second elastic structure 16 is one, the first elastic structure 15 and the second elastic structure 16 are respectively arranged between the first positioning portion 121 and the first pressing plate 13. When the number of the first elastic structure 15 and the second elastic structure 16 is multiple, the first elastic structure 15 and the second elastic structure 16 are respectively arranged at both ends of the first positioning portion 121 and the first pressing plate 13. Each second elastic structure 16 includes a second connecting member 161 and a second spring 162; third connecting holes are provided at both ends of the side of the second fixing portion 161 facing the first slide groove 1111, and fourth connecting holes are provided at both ends of the corresponding sides of the second clamping plate 14 and the second fixing portion 112. The number of the third connecting holes is the same as that of the fourth connecting holes and corresponds one to one; the number of the second connecting members 161 is the same as that of the third connecting holes or the fourth connecting holes and corresponds one to one, and the two ends of each second connecting member 161 extend into the corresponding third connecting hole and the fourth connecting hole respectively; each second spring 162 is sleeved on the corresponding second connecting member 161, and the two ends are respectively pressed on the opposite sides of the corresponding second fixing portion 112 and the second clamping plate 14.

[0044] In the tray clamping mechanism of the present embodiment, the outer diameter of each first spring 152 is larger than the inner diameter of the corresponding first and second connecting holes, preventing the end of the first spring from protruding into the corresponding first or second connecting hole, thereby preventing the first spring from effectively deforming. Similarly, the outer diameter of each second spring 162 is larger than the inner diameter of the corresponding third and fourth connecting holes, preventing the end of the second spring from protruding into the corresponding third or fourth connecting hole, thereby preventing the second spring from effectively deforming.

[0045] In combination with the above embodiment, the first connecting member 151 and the second connecting member 161 can be a pin, a height screw, etc. When the first connecting member 151 and the second connecting member 161 are height screws, the first connecting hole and the third connecting hole are respectively threaded through holes. The end of the first connecting member 151 passes through the corresponding first connecting hole and extends into the second connecting hole, and the end of the second connecting member 161 passes through the corresponding third connecting hole and extends into the fourth connecting hole. During the sliding process of the tray 2 along the first slide 1111, the first spring 152 is compressed in the vertical direction, thereby generating a vertical downward rebound force, thereby pressing the first clamping plate 13 against the draft edge 21. The second spring 162 is compressed in the horizontal direction, thereby generating a horizontal rebound force, thereby pressing the second clamping plate 14 against the tray 2.

[0046] In the tray clamping mechanism of the present embodiment, each of the third and fourth connecting holes is disposed on the side of the second fixing portion 121 and the second pressure plate 14, and the axis of each of the third and fourth connecting holes is disposed horizontally. Regardless of whether the angle between the second fixing portion 112 and the first fixing portion 111 is 90°, the pressure exerted by the second spring 162 on the second pressure plate 14 is ensured to be horizontal, so that the pressure exerted by the second spring 162 on the second pressure plate 14 is fully converted into positive pressure on the tray 2.

[0047] In the tray clamping mechanism of the embodiment of the present application, first mounting grooves 131 are provided on both sides of the bottom surface of the first pressure plate 13. The shape and size of the first mounting grooves 131 match those of the second pressure plate 14. The second pressure plate 14 is located within the first mounting grooves 131 and extends from the first mounting grooves 131 on the side away from the second fixing portion 112. Furthermore, the draft edge 21 protrudes horizontally by a set distance relative to the tray 2. As the tray 2 slides along the first slide groove 1111, the protruding draft edge 21 slides and extends between the first pressure plate 13 and the second fixing portion 112. Because the second pressure plate 14 is located within the first mounting grooves 131 and extends from the first mounting grooves 131 on the side away from the second fixing portion 112, the side of the tray 2 without a cutting edge slides into contact with the side of the second pressure plate 14 that extends out. The overall structure is compact, reducing the size of the clamping mechanism.

[0048] In the tray clamping mechanism of the embodiment of the present application, the end of the second clamping plate 14 extending out of the side of the first mounting groove 131 is provided with a slope 141, which contacts the side of the tray 2. The end is the end that is first slidably connected to the tray 2, so as to facilitate smooth sliding of the tray 2. Even if the side of the second clamping plate 14 is not precisely aligned with the first slide groove 1111, the tray 2 can slide along the slope 141 until it is aligned with the side of the second clamping plate 14, thereby preventing the tray 2 from being stuck by the second clamping plate 14.

[0049] Based on the same concept, the embodiment of the present application also provides a demolding plastic tray loading device corresponding to the tray clamping mechanism. Since the principle of solving the problem by the demolding plastic tray loading device in the embodiment of the present application is similar to the above-mentioned tray clamping mechanism in the embodiment of the present application, the implementation of the demolding plastic tray loading device can refer to the implementation of the tray clamping mechanism, and the repeated parts will not be repeated.

[0050] A mold-drawing plastic tray loading device according to an embodiment of the present application includes two tray clamping mechanisms as described above, wherein the two clamping mechanisms 1 are respectively clamped on two sides of the tray 2 where no cutting edge is provided.

[0051] like Figure 1 As shown, the ejection plastic tray feeding device of the embodiment of the present application further includes:

[0052] The loading lifting mechanism 3 is set to rise and fall in the vertical direction, and is used to transport the material tray 2 loaded with materials upward to the loading position;

[0053] The feeding clamping mechanism 4 is arranged relative to the feeding position, and the feeding clamping mechanism 4 includes a feeding clamping cylinder 41. The feeding clamping mechanism 4 presses and positions the material tray 2 at the feeding position in the vertical direction through the feeding clamping cylinder 41;

[0054] The horizontal material moving mechanism 5 is arranged relative to the material loading and clamping mechanism 4, and is used to horizontally move the material tray 2 located at the material loading position to the clamping position;

[0055] The two clamping mechanisms 1 are arranged relative to the clamping position and are respectively used to clamp two sides of the material tray 2 located at the clamping position.

[0056] In combination with the above embodiment, the whole box of material tray 2 is raised to the loading position through the loading lifting mechanism 3, and the loading clamping cylinder 41 drives the loading clamping mechanism 4 to separate a tray of material, and the horizontal material moving mechanism 5 pushes the material to the waiting position. During the pushing process, the clamping mechanism 1 is pressed down by the first clamping plate 13 and the second clamping plate 14. During the horizontal material moving process, the material tray 2 will also be clamped by the clamping mechanism 1. When the horizontal material moving mechanism 5 moves the material tray 2 into place, the clamping mechanism 1 clamps the material tray 2 and realizes the positioning of the material tray 2 at the same time, realizing the function of accurate positioning.

[0057] The rodless cylinder used in the horizontal material moving mechanism 5 of the embodiment of the present application can be replaced with a module if the CT requirement is higher.

[0058] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.
